0: Allies Copper Mine
Other names: Allies 2 - Sisengo - Changwe
The Allies Mine was first worked between 1914 and 1922, when 12 shallow shafts were sunk.Between 1962 and 1965, Charteredex sampled the shafts and returned grades of up to 5.49m averaging 3.23% Cu. Geochemical sampling outlined a north-south, 152m long anomaly >10,000ppm Cu. A 910m long 50ppm to 100ppm Cu anomaly to the north of historical workings was found to be underlain by laterite. Turam, self-potential electrical geophysical and magnetic surveys identified continuous linear targets over 180m in length, with strong anomalies to the north of the workings. Pitting and trenching within laterite over the northern anomaly was unsuccessful due to a shallow water table. A total of 14 diamond drillholes were completed within the main zone and into the northern anomaly, mostly to shallow depth (~100m). The best reported result within the main zone was 6.5m averaging 5.09% Cu, whilst no significant results are reported from the northern anomaly. Underground channel sampling at –60RL returned a best result of 1.52m averaging 8.31% Cu. Chartedex estimated an “indicated reserve” of oxide and sulphide ore, calculated with a 1% Cu cutoff, of 164,000t averaging 3.76% Cu.Recent artisnal activity has resulted in the identification of oxide copper mineralisation within shallow pits up to 200m south of the existing open pit.

17: Bwana Mkubwa (BMML FirstQuantum)
July 28, 2010 - Production will be suspended later in August. (Reuters)
Bwana Mkubwa had exhausted the copper ore oxide it imported from neighbouring Democratic Republic of Congo [Lonshi] and operations would be suspended until the plant sourced other economically viable raw materials.
HISTORY
• In May of 1997, the facility at Bwana was issued a large scale mining license for copper mining in the Ndola area by the government of Zambia, replacing the original mining license granted to the Company in 1996. In 1998, the Company completed construction of a 10,000 tpa copper cathode SX/EW tailings retreatment and sulphuric acid plant.
• In 2000, the Company discovered the Lonshi copper deposit and, in 2001, began construction and expansion at Bwana to enable the processing of ore from Lonshi. Further expansion in 2002 resulted in an increase in grade “A” copper cathode production capacity by 30,000 tpa. Tailings at Bwana were principally depleted in 2002 and Bwana,after completion of a modification program, began sourcing ore from Lonshi for the production of copper cathode.
• Further expansion, including the construction of the Bwana-Lonshi division’s acid plant in Solwezi, allowed Bwana to increase both its copper cathode and sulphuric acid production. On July 26, 2006, Bwana entered into a Development Agreement with the GRZ. In November 2007, the RDC-Zambian border between Lonshi and Bwana was closed for the export of ore from the RDC by the Governor of the Katanga Province. Mining continued at Lonshi and ore was stockpiled pending the expected opening of the border. The oxide resource was substantially depleted at Lonshi in August 2008. However, Bwana continued to source alternate sources of oxide ore in Zambia. In October 2008, Bwana announced the temporary suspension of copper cathode production, but continued to operate its acid plant. The Lonshi border was finally re-opened on November 5, 2009. The transfer of ore from Lonshi re-commenced on November 9, 2009 with Copper processing re-commencing on January 4, 2010.
PROCESSING
Bwana processes oxide ore [Lonshi-DRC exhausted] to produce copper cathode. Copper cathode is produced through a process of millings, leaching and SX/EW. Bwana owns four sulphuric acid plants, two of which are located at Kansanshi. Sulphuric acid plants incorporate sulphur burning to produce sulphur dioxide gas, gas cleaning and drying, conversion to sulphur trioxide and absorption, all of which result in the production of sulphuric acid.
FISHTIE OPEN PIT MINE PROJECT
In July 2009 Zambia approved First Quantum's plan to open a new copper mine in central Zambia to provide feedstock for the Bwana Mkubwa processing plant. First Quantum plans to mine 2.4 million tonnes of copper ore at the Fishtie deposit to supply feedstock to the Bwana Mkubwa plant at an estimated feed rate of 100 000 tonnes for month

18: Bwana Mkubwa Open Pit
Bwana Mkubwa was first worked around 700 AD and more recently during two periods, 1930-31 and 1971-1984. The latter 14-year period of production consisted of open-pit mining of mixed sulfide/oxide ore.
The level of mining in the area created large copper tailings and waste dumps, the largest of which, No. 4, covers 45 hectares. These dumps have been the initial focus of First Quantum's activities in the area. Various studies including a Bateman Engineering feasibility study completed in August 1996 concluded that there remains significant concentrations of recoverable copper on the property from tailings, waste and hard rock sources. Drill testing of only the No. 4 oxide tailings dump defined a reserve of 8.4 million tonnes grading 0.73% copper. In addition, Zambia Consolidated Copper Mines (ZCCM) reported 230,000 tonnes grading 2.54% copper in the west wall of the pit. A Watts, Griffiths and McOuat (WGM) 1990 report identified 900,000 tonnes grading 2.85% copper in the pit floor. Furthermore, WGM reported an additional resource of 3 million tonnes grading 1.4% copper in the immediate vicinity of the pit.

20: Chakwenga Gold Mine (ZRL)
Rhodesian Minerals Concession Company (RMCC) surveyed the Chakwenga area during a regional geological mapping campaign in 1934. Soil geochemical surveying and trenching lead to the discovery of numerous gold occurrences, including Chakwenga where trench results included up to 30m averaging 19g/t Au.Underground exploration via two shafts and an adit commenced in 1935. Results from sampling ofstrike drives returned intervals including 30m averaging 8.2g/t Au at 24m depth and 40m averaging 6.6g/t Au at 45m depth. At 115m depth the zone split into two smaller shoots grading 8g/t Au and 4g/t Au.
On the basis of “reserves” of 20,000t estimated at between 5.6g/t and 7.0g/t Au, mining was commenced in 1939. Intermittent mining between 1940 and 1942 reportedly produced 2,077oz Au and 78oz Ag. RMCC sold on its interest in the mine in 1943.No significant exploration at Chakwenga is documented until 1980, when a prospector estimated the tailings at 14,500t averaging 3.3g/t Au.Zamanglo is reported to have conducted copper exploration within the Chakwenga area during the early 1960’s, included trenching and diamond drilling, however no documentation of this work has been recovered.
From historical data, the region within a 10 km radius of Chakwenga is known to contain in excess of 20 other gold and/or copper prospects.

21: Chalalobouka Cu (ZRL)
AREA
RESOURCE BASE - HISTORIC
2.36Mt at 2.96% Cu Sulphides
0.7Mt at 1.87% Cu Oxides
HISTORY
Chalalobouka was reportedly discovered by Charteredex in 1959 via regional geochemistry, as a peak anomaly of 1,250ppm Cu. Soil sampling and mapping identified a 200m long anomaly >500ppm Cu.Pitting, Banka drilling and mapping defined oxide mineralisation at the 4/0/78 anomaly over a strike length of 900m. Diamond drilling on a 120m spacing led to a sulphide “reserve” estimate of 1.37Mt averaging 3.38% Cu.
Soil sampling located a second anomaly, A/90/18, 2km to the southwest of 4/0/78. Turam and selfpotential electrical geophysical surveys identified strong anomalies and resulted in the discovery of blind mineralisation estimated at 0.5Mt averaging 1.3% Cu. Mineralisation was traced up to 400m east and west of 4/0/78, and by 1965 an indicated and possible sulphide “ore reserve” was estimated of 943,100t averaging 3.06% Cu (2% Cu cutoff) plus an oxide “ore reserve” estimated at 272,000t averaging 1.5% Cu.
Between 1969 and 1972, ZAMEX completed additional diamond drilling and established a revised estimate of the “reserves” of 0.5Mt averaging 1.83% Cu in oxide mineralisation, and 3.3Mt averaging 2.12% Cu as sulphide mineralisation (1% Cu cutoff). A feasibility study on the deposits was completed, but no mining undertaken. The reasons for not proceeding to mining are not well documented, however RSG Global notes that options for metallurgical processing were limited relative 58 to modern processing, and that the timing of the study coincided with Government moves to nationalise the industry.
Between 1974 and 1975, Metalimex Mining Limited (Metalimex) completed limited diamond drilling at the 50/59 and 4/0/78 deposits. Revised “reserves” are reported, although the associated documentation is limited. Metalimex estimated oxide “reserves” at 0.7Mt averaging 1.87% Cu, and sulphide “reserves” of 2.36Mt averaging 2.96% Cu.

HISTORY
The first reported exploration at Chalimbana was by Rhodesian Selection Trust (RST) in 1955, when limited diamond drilling is reported. Between 1962 and 1965, RST completed diamond drilling and sampling of shafts (Figure 7) to establish an “indicated reserve” of 7.7Mt averaging 0.95% Cu, with a best intersection of 74.98m averaging 1.63% Cu.
Between 1970 and 1975, a winze was excavated to 67m vertical depth from which four horizontal diamond holes were drilled. Samples from the winze excavation and drilling were sent to Roan Consolidated Mines Research and Development Department for flotation and recovery test work.Results indicated that concentrates in excess of 25% Cu and generally containing 20% insoluble compounds, could be achieved with copper recovery greater than 90% or better. A feasibility study was completed, estimating “reserves” of sulphide mineralisation at 3.74Mt averaging 0.89% Cu,however the “computer” based estimation was subject to a number of uncertainties. No further work is documented.

May 13, 2010 - Interim Statement
The acquisition of
Chambishi was completed on 6 April 2010, whilst Comit was completed on 11 May
2010.
Acquisition of Chambishi Metals and Comit Resources
Eurasian Natural Resources Corporation PLC - ENRC today announces that it has entered into a conditional agreement to acquire 100% of Enya Holdings BV - Enya which holds a 90% interest in Chambishi Metals PLC, a Zambian copper and cobalt producer, together with a 100% interest in Comit Resources FZE, a Dubai-based marketing and sales company that historically has handled Chambishi’s copper and cobalt sales. The aggregate consideration for the Transaction amounts to US$300 million, which will be
wholly funded from ENRC’s existing cash resources. The Transaction remains
subject to the satisfaction or waiver of certain conditions precedent and is expected to be completed no later than the end of June 2010.
Chambishi is a mineral processing facility which produces copper and cobalt. It is the intention of the management of ENRC to combine Chambishi with the Group’s existing operations in the Democratic Republic of the Congo - DRC. ENRC currently plans to invest approximately US$80 million into Chambishi by the end of 2011, in new and upgraded production facilities. The investment should increase Chambishi’s copper production capacity to 55 kt per annum of London Metal Exchange (‘LME’)
Grade A copper cathode.
The integrated copper and cobalt mining and smelting businesses of Chambishi and those in the DRC, when combined, should have an improved cost position over time.The acquisition also enables ENRC to fast-track its copper and cobalt expansion and to achieve a higher planned level of combined total capacity, of 130 kt per annum of LME Grade A copper cathode and 12 kt per annum of cobalt contained metal salts and concentrates by 2012.
Chambishi’s current facilities comprise a roast leach electro-winning plant - for the processing of oxide concentrate, sulphide concentrate or intermediate metal salts - and an electric arc furnace and a pressure oxidation leach plant for furnace slag treatment. Chambishi also owns a slag dump of approximately 16.6 million tonnes, with an average grade of 1.10% copper and 0.71% cobalt
Current copper production capacity at Chambishi is 25 kt per annum of blister grade copper. Chambishi is also a substantial producer of cobalt, one of the largest in the world, with a current capacity to produce 6 kt per annum of refined cobalt metal. The cobalt metal produced at Chambishi is high-grade and has strong brand recognition in the industry.

3.2.1.7 Production Capacity
The NFCA concentrator at Chambishi Mine was designed to crush 6,500 tons of ore per day, mill 6,500 tons of ore per day and concentrate 379 tons of copper concentrates per day with a grade of 40%. The concentrator's production recovery is 95.5%. However, the plant is currently operating at half capacity because only about3,500 tons of ore per day are received from the underground operations. The copper concentrate production output is anticipated to improve with increasing ore output from the underground operations.
3.3 Potential Future Developments at Chambishi Mine
NFCA is committed to increasing its investment in Zambia by widening its scope of mineral development. The company intends to undertake the following developments in the future:
Extension of the underground mining rights area to cover a 100 km2 area;
· Increasing mining and processing rates;
· Development of the Chambishi west ore body;
· Development of the Footwall reserves;
· Construction of a sulphuric acid plant;
· Construction of a leach plant for reclamation of copper from low-grade ore;
· Construction of a smelter.
With regard to the reclamation of copper from low-grade ore, it is envisaged that copper will be reclaimed as follows:
Low grade oxide ore from ore stock piles No.'s 3 and 4 will be reclaimed by a process involving heap leaching, solvent extraction, and electro-winning;
· Fine oxide ore from tailings dams No.'s 7, 7A, 8, 9, and 15 will be reclaimed by a process involving agitation, solvent extraction and electro-winning; and
· A process involving heap leaching, solvent extraction and electro-winning will reclaim vat leach tank residue from tailings dam No. 10.

Tailings Dam 6 is a pollution control facility used to clarify effluent from both the NFCA and Chambishi Metals plc operations. The effluent is transported from the NFCA mine site and the Chambishi Metals plc site via a series of open drains that empty into one main canal leading to the TD 6 inlet.
Originally, the Chambishi stream, which ran through the Chambishi Mine site, was diverted so that it would carry effluent from the mine site to TD 6. In case of floods, provision has been made to bypass flood flows so that only part of the discharge is diverted onto the dump whilst the remainder is routed in a channel around the dump to rejoin the diverted Chambishi stream at the TD 6 decant outlet. Effluent from the TD 6 outlet is discharged to the New Dam, which in turn discharges into the Chambishi stream.

CSU Marches into Zambia for Tailings Exploitation
The Central South University inked agreement with Zambia's Ministry of Mining Industry & Mineral Products Exploitation on the morning of June 23 in Changsha, and both sides are to conduct comprehensive collaboration. Maxwell, minister of the Ministry of Mining Industry & Mineral Products of Zambia, Gao Wenbing, secretary of the Party Committee of the Central South University, and Huang Boyun, president of the university, attended the signing ceremony.
As the fourth biggest state in copper production in the world, Zambia's accumulative tailings amounted to several billion tons, causing not only heavy metal pollution but also huge waste containing several million tons of copper. The Central South University takes the lead in biological copper extraction in the world, and its technology in this field can improve the copper extraction rate from the tailings for Zambia by over 30%.
With the technological support of the Central South University, the used-to-be "burden of Zambia" may be transformed into a treasure to safeguard the resource security of China.
According to the agreement, the Central South University will provide technological support to Zambia in terms of fully utilizing the tailings, solving the environmental problems and tapping mineral sources, and cultivate local senior talents for the state.

The Musakashi Tailings Dam (TD 19) is an active, classified dump situated about 10 km north of the Plant Area. It consists of an earthfill embankment which was 360 m long and 15.5 m high
since 1996. The dam is due to be extended in two phases, so as to increase its tailings containment capacity. During the first phase, which is on-going, the embankment wall is being extended to 700 m long, and to 21.5 m high. During the second phase of extension the dam, the height of the dam will be extended by a further 4 metres to 25.5 metres. The crest width is 3m. The TD was originally designed to have a capacity of 5.7 million tonnes, but provisions were made to raise the embankment to increase storage capacity to 23 million tonnes of material. The tailings dam receives tailings from the concentrator at the NFCA mine site, and the tailings are transported to the dam through a refurbished tailings pipeline

Chayinda was discovered in 1934 when pitting and trenching by Rhodesia Minerals Concessions Ltd (RST) returned up to 62.9g/t Au. In 1960, RST conducted geological mapping, geochemical sampling and magnetic and radiometric surveying. Trenching showed mineralisation to be thin, with intervals up to 0.6m averaging 2.12g/t Au. In 1976, the Zambian Ministry of Mines conducted mapping, panning,magnetic and gravity surveying, soil sampling, trenching and pitting. Eleven vertical diamond drillholes were completed for a total of 544m. Samples were analysed by atomic absorption spectrometry (AAS) methods. The work led to the estimation of “proven reserves” of 79,300t averaging 5g/t Au plus a “probable reserve” of 77,600t averaging 5g/t Au.

HISTORY
The first documented exploration of the Cheowa and Neningombwe prospects was by RMCC, which completed regional mapping in the early 1930’s. Exploration within the Cheowa shear zone is reported by later investigators, although details of this work are currently unavailable. In the 1960’s, Charteredex completed drainage and soil sampling surveys, sampling of old workings,geophysical surveying, trenching, and a programme of 11 diamond drillholes (Figure 8). Soil sampling defined an anomaly of greater than 200ppm Cu approximately 300m in width and extending for 14km along the shear zone. Sampling of RMCC shaft and adit cross-cuts returned up to 2.0% Cu over 3.7m and 2.2% Cu over 5.4m. Gold values varied from trace to 3.75g/t Au. At Neningombwe, narrow mineralisation exposed within adits included up to 0.34m averaging 6.0% Cu with gold up to 0.9m averaging 9.9g/t Au.Trench sampling over soil anomalies at Cheowa and Neningombwe identified up to 13.7m averaging 1.12% Cu and 3.8m averaging 1.11% Cu, respectively. Diamond drilling was completed at the Cheowa prospect with a best intersection of 2.96m averaging 5.41% Cu from 70m depth. Selective gold assaying of core containing in excess of 1% copper showed a maximum of 0.48m averaging 7.78g/t Au. Mineralisation was reported to remain open at depth

Copper mineralisation is hosted by quartzite in the footwall of the OS1 Member at the Chingola ‘B’, Mwambashi ‘B’ (Mwambashi Copper Project), Chibuluma, Fitula and Mimbula mines. The host units are located in fault bounded sub-basins to which the overlying shale has acted as an impermeable barrier and reductant for mineralised fluids. It has been postulated that hydrocarbons trapped in the arenaceous footwall sediments may also have acted as reductants that have controlled precipitation of sulphide minerals from mineralised fluids. Whilst having smaller resources than the ore shale deposits, typically several tens of millions tonnes, the grades are generally higher at 2.5% to 4% Cu, with varying Co grades.

The Chibuluma Mine complex is situated near the town of Kalulushi, which is approximately 12 km west of the Kitwe, one of the metropolitan and industrial centres of the Zambian Copperbelt. The current mining area is Chibuluma South, some 13 km from the town of Kalulushi.
The topography is generally flat, with elevations above mean sea level of 1 220m to 1 300m at Kalulushi. As with the rest of the Zambian Copperbelt, the weather is tropical with the rains occurring in summer, and are particularly heavy in April. Potable water is supplied to the town of Kalulushi.
Electricity is readily available on the Copperbelt, and supplied by Copperbelt Energy Corporation to the mine and town. The Copperbelt itself is well supported by road, rail and air services. An international airport at Ndola, an hour's drive from Kitwe, services the Copperbelt.
The main road links are all tarred, and Kitwe and the Chibuluma Mines are linked by rail to the Zambian rail network as well as to the countries to the south of Zambia. Copper from the smelters and refineries on the Copperbelt is exported mainly through Durban in South Africa, however other links exist to both Tanzania and Mozambique. This infrastructure has been in place since the early days of the copper mining industry.
HISTORY
Chibuluma Mine began production in 1955 as a self-contained unit producing copper concentrates, which were treated at the Mine concentrator. However the concentrator was closed in 1991 and the ore has been treated locally. The Chibuluma South deposit was discovered in 1969.
Chibuluma Mine began production in 1955 as a self-contained unit producing copper concentrates, which were treated at the Mine concentrator. However the concentrator was closed in 1991 and the ore has been treated locally. The Chibuluma South deposit was discovered in 1969.
The Copperbelt Mines were nationalised and merged into Zambia Consolidated Copper Mines (ZCCM) in 1982. Subsequently, Chibuluma was the first mine to be privatised, being acquired by a Metorex consortium in October 1997 with ZCCM/Zambian Government retaining a 15% interest. Chibuluma South is the first new underground mine to open on the Zambian Copperbelt in 30 years.
The town of Kalulushi was developed to support Chibuluma Mines in the early 1950's. When the Chibuluma East mine was closed, the excess housing and facilities became available for use by ZCCM corporate and technical officials. The town of Kalulushi thus houses a number of ZCCM corporate divisions, and on the privatisation of ZCCM, many of these employees purchased the houses they resided in and still continue to live in the area.
Kalulushi is a mining village with approximately 3 300 houses, situated some 12 km west of Kitwe, the principal town on the Copperbelt, was developed to support Chibuluma Mines. It has its own recreation club, golf course, hospital, school and clinic as well as a small shopping facility, and the town is accessed by a tar road from Kitwe. The town is supplied with electricity by ZESCO and receives a potable water supply from Kitwe. Kalulushi has its own sewerage works and internal water reticulation. It is linked into National Zamtel telephone network.

July 15, 2010 - Chingola copper dumps project
The largest rock dump at Luano, OB18, comprises mineralized overburden of the Lower Roan Group sediments which comprise mineralized arkose sandstones, grits and schists. Given the synclinal nature of the ore bodies that were stripped, and the pervasive nature of the copper mineralisation throughout the stratigraphy, there is extensive oxide copper mineralization in the overburden dump. Visual inspection of the rocks comprising the dump confirms the presence of copper oxide minerals including extensive malachite as the dominant copper mineral and chalcocite as the sulphide coppermineral.

Mr Kumar said KCM had employed 100 more workers to operate the reclamation project at TD3. "When the Fitwaola Mine is re-opened, we shall create more jobs because we are looking at engaging 300 employees to work there, so jobs will be created at the mine,"Mr Kumar said.
He said they expected to produce 2000 tonnes of cop a month from the reclamation project at TD3. Meanwhile, Mr Kumar said KCM has pumped $10 million into the reclamation project at TD3.
He said reclamation was the cheapest way of extracting copper but that the project would help in sustaining the running of the mines. The project at TD3 was expected to run for 15 years and that they had re-opened TD3 in advance because the current one would run out in the next two years.

95: TD7 - Chingola (FraserAlexander KCM Vedanta)
Tailings Dam 7
Fraser Alexander™s tailings operations in Zambia are based in Chingola, where various hydro-sluicing projects are operated for Konkola Copper Mine. Initially, the mine only used the TD2 tailings dam as a deposition facility for its copper tailings, while the runoff water ran into the pollution control dam (PCD). Since the dam was proving to be inadequate to handle the tailings volumes, further dams were built.
Fraser Alexander was asked to put together a plan to re-mine the TD7 tailings dam, which was implemented within three weeks, an aspect which gave us the edge over our competitors with regard to delivery time. The high-pressure water pumps and slurry pumps were installed within three days.
Currently 10 000 tons of tailings are pumped from TD7 per day, amounting to 300 000 tons per month.
A new approach was suggested for the removal of slime from the PCD, which was not producing the required volumes. The installation of a barge with a new pump and the use of the latest hydro-sluicing equipment have improved the recovery of slime from the PCD to such an extent that the dam has surpassed its target beyond expectation.
Based on Fraser Alexander’s successes with the Konkola tailings dams, the mine requested that the company establish re-mining solutions for TD3a and 3b. All the planning has been completed to start operations in February 2009. The last phase will involve implementation of the TD5 re-mining solution. The next step is the implementation of an overall maintenance plan for the entire tailings site.
The Konkola project has been characterised by exceptional delivery times, good working relationships and transparency in all communications. We believe that our approach has proven that Fraser Alexander has the cutting edge expertise to provide an innovative solution to any tailings challenge.

Update April 30, 2010
Assaying of a significant backlog of drill samples from Kangalui and Chisawa projects from the last field season’s work program commenced during the quarter and interpretation of the assay work is underway. The results of this work will be reported when the geological analysis and data validation is completed in the next few months. This work may produce an initial JORC compliant resource estimate for this project.
August 20, 2008
Commenting on the announcement, Julian Ford, Managing Director of Zambezi Resources, said:
“These excellent drill results from Chisawa over a 2km strike length confirm our opinion that the Kangaluwi Copper Project has the potential to develop as a world-class copper asset and a company-making project..."
New RC drillhole intercepts from Chisawa include: 14m at 1.52% copper, 12m at 1.36% copper, 10m at 1.23% copper, and 14m at 0.65% (Table 1, Figs 1, 2 and 3). Further assays are awaited to confirm strong zones of visual mineralisation observed in drilling. The mineralised zone remains open down dip and along strike to the east and west.
Mineralisation at Chisawa consists of chalcopyrite, bornite, malachite, azurite and secondary chrysocolla in the oxide zone. The host sequence consists of sheared metasediments, metavolcanics and a late stage, conformable coarse grained felsic pegmatite. Mineralisation is hosted within strongly foliated garnet-quartz-biotite-muscovite schist and feldspar-quartz-muscovite-kyanite pegmatite. Mineralisation dips moderately to the south west at approximately 30-40o and occurs within the sheared southern limb of an overturned ESE-plunging regional synformal fold.
Initial drilling at Chisawa targeted surface malachite mineralisation coincident with a >250ppm copper in soils geochemical anomaly over a north west – south east trending strike length of 7.2km. The significant results reported here come from the core of this anomaly which consists of a 3.1km strike length at >1000ppm copper in soils. The soil geochemistry conforms to a mapped and interpreted lithological and structural corridor. A strong correlation between the >1000ppm Cu contour and higher grade copper mineralisation is evident in the RC drilling. Drill testing of this zone to date is via widely spaced drill sections with a nominal distance between sections of 200-400m.
The greater Kangaluwi project covers in excess of 28km of strike length (see Fig 1) and detailed drilling has tested only approximately 3.5km strike length to date at Kangaluwi. At the neighbouring Chisawa prospect, drilling has sparsely tested only approximately 3.5km strike length. 75% of the estimated total prospective strike length of the greater Kangaluwi project remains to be drill tested.

The new results confirm the discovery of significant grades and thicknesses of sandstone-type uranium mineralisation. Mineralisation is near surface and likely to be amenable to open pit extraction.
Two parallel mineralised zones have been identified, with strike lengths of up to 800m. Both zones remain open along strike. Additional RC drilling is scheduled to commence in the second quarter of 2008, after the seasonal rains have ceased.

Tin, together with tantalum, was being mined on an irregular basis by small-scale workers from the Tin Belt of southern Zambia, east of Choma. Tin occurs as cassiterite in pegmatites and in placers. Stanniferous quartz-muscovite-feldspar-tourmaline pegmatites intruding schistose metasediments occur over a strike length of 100km centred on Masuku Mission and approximately 150 separate occurrences have been recorded. The average annual production was around 10t of tin-tantalum concentrate and was sold as such to local processors.

Early 2007 we began mapping and sampling at our 400 hectare manganese project at Chiwefwe, near Mkushi in Zambia. This was followed by a 15 hole shallow RAB drill programme to test for good grade mineralisation extending to depth. The results enhanced our understanding of the deposit, and some holes ended in mineralisation. The grades encountered were variable, as were those from a sampling programme on the several thousand tons contained in old stockpiles on site. A scoping study was carried out by CSA Consultants Ltd ("CSA"), which concluded that production was likely to be practicable and economic, provided that reliance could be placed on the assumptions made on tonnage and grade.

History:
The first reported exploration of the Chongwe South deposits is by Chartedex in 1962. The Lucky Jim and Kanakantapa Prospects were detected in systematic soil geochemistry surveying and electrical 57 geophysical and magnetic surveys undertaken. Drill testing of oxide mineralisation returned results from 1.5m averaging 1.30% Cu to 4.3m averaging 2.40% Cu over a strike length of 290m. On-going programmes of detailed geochemical and geophysical surveys extended the zone of mineralisation and located the Porcupine and Robuko prospects (subsequently referred to as the ‘A’ and ‘B’ Lenses). By 1972, exploration has identified “reserves” at the various prospects totalling 1.55Mt averaging 1.55% Cu as sulphide mineralisation (1% Cu cutoff grade), and a further 0.55Mt averaging 1.62% Cu in oxide mineralisation (0.4% Cu cutoff grade).

Zambias Collum coal mine to quadruple output by 2008
Mr Xu Jian Xue, chairman of privately-owned Collum Coal Mining Industries Ltd, told Reuters in an interview his firm expected to double its production to 240,000 tonnes in 2007 and then lift it to 480,000 tonnes the following year. "There is high demand for coal from the copper mines and we currently cannot meet that demand as we are still growing. The business atmosphere is looking good and, coupled with a friendly investment atmosphere we should be able to grow" Mr Xu said.
Mr Xu said demand for coal was also rising from Zambia's largest cement producer, Chilanga Cement Plc, due to the government's plans to start constructing two new power plants and many housing units this year.
Collum Coal Mining Industries is owned and run by five Chinese brothers who each invested a total of $5 million to start mining coal in Kandabwe, 400 kilometers south of the Zambian capital Lusaka. Collum Coal Mining Industries started production with output of 10,000 tonnes of coal per month last January

Mkushi Exploration completed to date:
The original claims for Mkushi were transferred to Falcon Mines (Falcon) in 1926. Falcon carried out a programme of geophysical prospecting, identified a series of anomalies which were subsequently confirmed to be mineralised and reported an “in situ resource” of some 100,000 t at 4.5% Cu. Falcon, however, considered this to be too small and suspended operations.
In 1956, a pilot scale plant was brought in to conduct metallurgical test work. Reportedly, some 2,300 t of copper were recovered from some 70,000 t of ore milled, equating to a recovered grade of 3.5% Cu. Operations were suspended due to low copper prices until 1966, when L.G. Nichols obtained an option over the property. Two additional mineralised zones were located using geophysics and subsequent diamond drilling showed the deposits could be worked profitably by open pit methods. Financial difficulties, however, precluded Nichols from developing the property.
In 1968, Mkushi Copper Mines together with an Italian Mining company, Miniera di Fragne Chialamberto, began open pit mining at Munshiwemba. The pit reached a depth of 30m and yielded 2.2 Mt of ore at 1.0% Cu until operations ceased in 1975.
Work by African Eagle Resources, since it acquired Mkushi in 1998, has included Landsat and aeromagnetic interpretation, soil sampling, rock chip sampling and geological mapping. The soil sampling programme covers most of the licence area. At the Coloquo prospect, the sampling defined a consistent copper anomaly of greater than 100 ppm over 500m long by 130m wide, with some low order zinc anomalism peripheral to the main anomaly. At the Mtugu Prospect, infill soil sampling returned assays up to 305 ppm Cu, 72 ppm Zn and 30 ppm Pb, although no consistent anomalies were defined.Limited rock chip sampling undertaken at both the Mtuga and Coloquo prospects returned values up to 14 g/t Au, and samples of tailings returned values of up to 0.48 g/t Au, indicating a potential coppergold association.

Zambian deposits such as the Dunrobin mine (Au), Kansanshi (Cu, Au),Nampundwe mine (pyrite, Cu, Au?) and Kasumbalesa (Fe, Au?) on the Zambia D.R.Congo border also display characteristics of IOCG deposits. Relation to granitoids at these four operating mines is not evident. They are all fracture-controlled and display evidence of strong hydrothermal activity. Intrusive rocks that heated the systems are thought to be nearby and under cover. Many small IOCG prospects have been explored around the Zambian Hook Granite during the past ten years. None have been large or rich enough to warrant large -scale mining. Sites like the Hippo, Kalengwa and Lewis-Marie mines and the Luiri Hills, Shimyoka and Lou Lou prospects contain IOCG mineralization and determine a large prospective province.

A solitary ore schist horizon of 8 – 14 m thickness was intersected, and it remains open to the north, south and west. Sulphide mineralogy is exclusively chalcopyrite and rare trace uraninite, and in terms of sulphide assemblage and copper grades the mineralization bears similarity to the ore zone at Chimiwungo rather than Malundwe. The mineralization is hosted in a different thrust sheet from Malundwe.

S. African zinc mine start stalled (page 3/21)
June 18, 2008
Zambia's High Court has cleared South Africa-based Alberg Mining and Minerals Exploration to proceed with the revival of mining operations at the closed Kabwe zinc and lead mine following the dismissal of a suit filled by a rival company early this year over mining rights.
March 8, 2007
Silver Lining Ventures plans to restart the mining and processing of zinc, which was abandoned in 1994 when the Kabwe mine - one of the oldest in Zambia - was abruptly shut due to poor management and lack of capitalisation.
"We are rehabilitating some of the equipment which was abandoned and all we have to do is to clean it up because the steel structures in the plant are very strong and can be used for many more years," he added. Nabulyato gave no timeline on when the zinc and lead operations would start but said Silver Lining Ventures planned to open three mining shafts at its zinc mine. "We will also be processing lead on a small scale," he added.

HISTORY
Zambia's recent lead and zinc production came from the Kabwe mine operated by ZCCM. The ore grade of this old mine, over 80 years in production, was 23% Zn and 10% Pb. The mine was closed in 1994. However, the level of resource in the Kabwe mine area is estimated at 50Mt with 3.8% Zn and 1.8% Pb.
GEOLOGY
The Kabwe zinc deposits, in central Zambia, produced approximately 12.3 million tonnes of ore containing 25.2% Zn and 10.7% Pb. The mines were, at times, also a source of Ag, Cd, V2O5 and Cu. The Kabwe deposits occur in metasedimentary rocks of the late Proterozoic Katangan Supergroup. In the Kabwe area these metasedimentary rocks appear to have been subjected to at least two major periods of folding, as well as later faulting. The first phase of deformation resulted in the formation of tight WNW- to E -W-trending, isoclinal folds with amplitudes up to several kilometers and low-angle reverse faults. These folds are cut by a number of generally NE-trending, high-angle faults. Both the reverse faults and the NE-trending faults are important controls on mineralization.
The Kabwe district contains three distinct styles of mineralization: 1) irregular bodies of massive sulfides and/or willemite; 2) zones of veinlet-controlled sphalerite and willemite with small, irregular pods of more massive mineralization; and 3) supergene “blankets” overlying subcropping massive or veinlet-controlled sulfide and willemite zones. The Kabwe deposit consists of seven clustered bodies within the Main Zone and the No. 2 orebody located approximately one kilometer southeast of the MainZone. The Main Zone orebodies occur as pipe-like to vein- like shapes, generally plunging to the northeast at 30 to 50° with down-plunge extents from 20 m to greater than 800 m. In plan view the bodies have dimensions from less than 100 m to greater than 200 m in length and 10 m to 40 m in width. Massive sulfide ore in the Kabwe Main Zone orebodies consists of sphalerite, galena, and pyrite with minor to trace chalcopyrite. Willemite is rare in these sulfide assemblages; where present it forms small grains enclosed by sphalerite. Pyrite occurs throughout the orebodies and also forms massive zones on the edges of some orebodies. The sulfides are medium- grained and display
granoblastic, polygonal textures suggestive of recrystallization during strain.

Pyrite tails (Sable) could also contain 443,600t of Ore (39,900t of Zn and 12,000t of Pb). Other Dumps (Sable) could also contain 169,900t Ore (16,800t of Zn and 6,800t of Pb).
In total, 168,900t of Zinc and 46,500 of Lead could be contained in the BMR and Sable Sections. At a processing rate of 50,000 tons per month the life of these Dumps will be approximately 4 years.
The head grade of these Dumps is 215,400 tons of metal (8.94% mineralization). Of this total, the amount of metal attributable to BMR is 124,941 tons (98,140t of Zn and 26,801t of Pb).
At a LME metal price of US$1,800/ton the sales value of the metal attributable to BMR in this resource would be US$235 million over the 4 year processing period.
At a 70% recovery rate (30% processing loss), 87,459 tons of Zn and Pb could be recovered and sold by BMR.
Leaching or toll milling of the ore and sales of product as concentrate are considered to be the initial best production options for the Company.

10 January 2006
Spirit of the River, a Canadian firm that has done alluvial sapphire mining in Madagascar and other alluvial mining in South Africa, has now turned its attention to looking for diamonds in the riverbeds of Barotseland in Zambia’s Western Province, reports the Lusaka Post.
Zambia’s Western Province borders on Angola, and Spirit of the River President Dave Schaffer pointed out in an interview with the newspaper that rivers tend to flow from Angola into Zambia, presumably bringing diamonds with them that could be buried deep under the river sediments, where they can best be reached with dredging technology like his firm’s. Feasibility studies have already been carried out on the Barotse River floodplain, using hovercraft.
Schaffer said full-scale mining will start in January, with about 60 local people already employed. His company has invested $3.5 million (U.S.) in the venture, including $1.5 million for “aqua-mining” equipment from South Africa. The focus of attention is areas like Kalabo and Shangombo, near the Angolan border.
Spirit of the River has been in business for 18 years, including eight years mining sapphire in Madagascar. Schaffer said his firm’s technology is environmentally friendly

Hetro Mining?
1971:
The Kalengwa mine, situated in a remote area of Zambia in Central Africa, has presented some unique problems to the planners engaged in developing the deposit. This small, high grade copper deposit contains some 1,688,000 tons of ore at a grade of 9.3% contained copper. Of this 362,000 tons is classified as high grade ore at 27.2% Cu, the coarse fraction of which can be fed directly to converters; 733,000 is classed as intermediate grade ore averaging 6.3% Cu, and 593,000 tons classed as low grade ore containing 2.1% Cu. The geology of the deposit and the establishment of the mining operation is fully described. A concentrator is being built at Kalengwa to treat the high grade fine product, intermediate, and low grade ore, whilst the coarse high grade ore will be trucked to the Copperbelt smelters for direct smelting. Details of metallurgical processing are given. The decision to truck the coarse high grade ore to the smelters on the Copperbelt necessitated the construction of a new 200-mile road, the setting up of a fleet of heavy ore transport trucks and associated equipment. The remoteness of the area from established communication facilities on the Copperbelt necessitated the provision of radio communications between Kalengwa and the head office at Kalulushi, and the establishment of a regular mine air service. The paper also describes the training of an unsophisticated local population in the operation of heavy plant and machinery, the establishment of the township, and the provision of health services.

At Karibarembi, Anglo completed extensive geophysical surveys including drilling (13 diamond drill holes) with the best intersection of 0.75 meters at 22% copper reported. No analysis for gold seems to have been completed however there is scheelite, copper and pyrite and refractured quartz veining within breccias in the area.
Shirembwe hosts numerous malachite stained boulders. Some trenching has been completed but results are not known at this stage. Further investigation is continuing. Chimena has over 140 wagon wheel drillholes and three diamond drillholes with copper mineralisation visible. In 1991 Watts Griffis McOuat, an independent firm of consulting geologists and engineers, considered in an independent review that the area may have potential for Carlin-style gold mineralisation based upon the widespread hydrothermal silicification and sulphide mineralisation. Additionally the carbonate rocks in Kundelungu, with high levels of sulphidation and late tectonic acid intrusive may lead to high grade skarn mineralisation not yet explored for.

CHIMAN Manufacturing Company - CMC of Kabwe has asked squatters encroaching on its manganese mining land in Kampumba area to move out failure to which the company will use force. CMC sales manager Tina Cui said in an interview in Kabwe yesterday that a Mr Andrew Mazimba and his workers had encroached on their designated land and were engaging in illegal mining. “We have sought legal redress through court orders asking this Mr Mazimba to vacate our premises and stop carrying out illegal mining activities on our land. He is occupying about 400,000 square metres of our mine land illegally,” Ms Tina said.She said her company came to Zambia to do business and she was saddened that Mr Mazimba wanted to disturb the company operations by illegally occupying the mine land. The company has invested about US$5 million in its manganese plant. The firm, which resumed production in February this year, plans to increase investment to a total of $8 million in its operations in the once-famous mining town. “It is sad that we are being treated in this manner even when we have a court redress and a mining licence. I am therefore appealing to the Zambian Government to assist us persuade these people to move failure to which we shall be forced to use force,” Ms Tina said. The company produces about 15 tonnes of manganese everyday for export to South Africa based on demand.
“Our intended investment is U$8 million but we have so far put in U$5 million in our operations. We are getting our raw materials from our Kampumba mine which is 83 kilometres from our processing plant,” she said. It was hoped that the company would increase the workforce from the current 100, once expansion works were completed. It was still struggling to settle down as Zambia lacked the market for manganese metals. It was hoped that once the Kafue Steel Plant became operational, a local market for manganese would be found. The firm also has no intention to pollute townships surrounding its processing plant and that was why it has procured filter elements to deal with the problem. CMC has been in existence for about five years and only commenced production late last year.

GEOLOGY
Several occurrences of graphite and manganese are reported from the project area, notably the Kampumba manganese mine in the northeast of the licence. The manganese orebodies occur over a distance of 2.5 km along the top of the Kampumba Hills, and form a residual capping over strongly folded manganiferous dolomites, intercalated with schists, gneisses and quartzites. The manganese (Mn) content of the wad ores varies from 38% to 61% Mn, with up to 69% iron (Fe).

HISTORY
The Kampumba licence contains multiple prospects and geochemical anomalies, over which relatively little exploration has yet been carried out. They include many historical gold prospects and the old Kampumba manganese mine. The 5.5km long Tandalwe copper geochemical anomaly was tested in the 1960s by extensive trenching which revealed up to 2% copper over widths of 3m. At that time a solitary diamond drill hole at the location of the better trench results on Tandalwe Hill gave a mineralised intersection of 57m. Significant silver content was recorded but no gold assays were made at the time.

148: Kansanshi History (First Quantum)
History:
The Kansanshi deposit is the site of one of the oldest known mines in Zambia, with evidence of direct copper smelting dating back to the fourth century. Since the rediscovery of these ancient workings in 1899, the deposit has been mined intermittently for recovery of high grade copper ore.From 1903 until 1914, copper was recovered by underground mining of high-grade veins, followed by hand sorting and direct smelting. Mining activities terminated with the onset of World War I, resumed in 1927, but were shut down again in 1932 due to the world wide economic depression.
In 1952, further exploration and mine development commenced, with production resuming in 1956. Rich oxide ore from the upper levels of the underground mine was shipped to Nkana on the Copperbelt for direct smelting. Sulphide concentrates were also produced on site from rich vein ore from lower mine levels through a small concentrator. The concentrates were shipped to the Nkana smelter for processing until October 1957.
In 1969, Zambia Consolidated Copper Mines (ZCCM) approved development of an open pit mine at Kansanshi to treat high grade oxide ore in a leach plant to be constructed at the Kansanshi site. Construction commenced in 1974 with the building of houses and an office block but the project was shelved at the end of 1975 due to low copper prices. In June 1977, a “mining only” option was initiated at Kansanshi to deliver oxide ore to the Copperbelt for treatment and copper recovery at the Nchanga leach plant. This activity continued through April 1986 when operations ceased for economic reasons. During 1988,ZCCM constructed a small sulphide flotation concentrator at site with a capacity of approximately 200 t/d and recommenced open pit mining activities. Concentrate from the facility, containing up to 15 g/t Au, was transported to the Copperbelt for smelting. This operation continued until January 1998, at which time ZCCM formally ceased operations and initiated closure and reclamation activities. Total production of copper from the Kansanshi deposit to date has been approximately 80, 000 t.
In January 1997, as a part of a privatisation programme, Cyprus Amax Minerals Company (Cyprus) entered into an agreement with ZCCM and the Government of the Republic of Zambia to secure majority ownership of surface leases and selected assets associated with the Kansanshi project. Cyprus initiated geological investigations and
metallurgical testwork in May 1997, aimed at developing reserves capable of supporting a major copper mining facility. Cyprus became a part of Phelps Dodge during the undertaking of a Preliminary Feasibility Study (PFS). This PFS examined Cu production of 124 000 t/a over a 24 year life, from mining of a total of 267 Mt of ore. This comprised 101 Mt of Mixed ores requiring flotation and leaching, together with 166 Mt of Sulphide ores requiring only flotation. Following submission of the PFS, Phelps Dodge determined that the Kansanshi Project did not meet its corporate requirements and tendered the Project for sale.
FQM acquired majority ownership and management control of the Project, reviewed a number of options and determined that a progressive development plan, initially focussing on near surface, higher grade, leachable ores, was more appropriate. Phase 1 of the development plan, which is the focus of the DFS, visualises production of 60 000 t of cathode copper per annum, plus variable amounts of copper in flotation concentrates, while minimising capital investment. Future plant upgrades would entail staged expansion of the throughput capacity to allow treatment of lower grade Sulphide ores and, ultimately, installation of facilities for on-site treatment of sulphide concentrates.

Veins are N-S striking and sub-vertical. Some veins are discrete, continuous sheets which are traceable over 100’s of meters. More commonly, individual veins are narrow tension-gash shaped structures which form swarms or corridors. These are continuousover several hundred meters. Individual veins are 1m to 15m wide, but vein swarms may be up to 90m wide. Veining is crowded, with one vein or vein swarm every 50m or so. Veins sit within a 350m wide zone of faulting which is detected in drillhole sections by changes in thicknesses of stratigraphic units, as well as intersections of fault breccia. Veining is continuous through all the upper stratigraphic units, and from limited deeper drilling, appear to penetrate the LPS. Weathering is intense at shallow depths, and partial weathering with supergene mineralisation persists to depths of up to 300m below surface.

KARIBA AMETHYST MINE
50% Gemfields
The Company is currently considering an expansion of production (conceptual study dated April 2007, the Kariba Conceptual Study) at Kariba by 300% from the current (annualised 9 months to 31 December) 1,420kg of amethyst at a cash cost of US$1.83/kg to 4,400kg of amethyst at a cash cost of US$2.50/kg in the 5th year of the expansion. This is to be achieved by
increasing ore processed from the current 32,000tpa (annualised) to 75,000tpa, total material mined from 280ktpa to 3.5Mtpa, RoM grade from 37.1kg/t to 68.1kg/t and human resources from 400 to 733. Total capital expenditure requirements in year 1 are assumed at US$7.3m with annual
sustaining capital expenditures of some US$1.7m thereafter. This expansion scenario is also supported by an assumed increase in the sales price from the current US$1.96/kg to US$3.89/kg.

At the Kashitu West target, disseminated sphalerite (2% Zn to 3% Zn) and minor galena were intersected in the majority of the drillholes. The sulphides occur as disseminated blebs suggesting precipitation in open spaces in the carbonate host-rock. Zinc silicate mineralisation in the form of willemite was also encountered in some drillholes. The willemite appears to overprint or replace the sulphide mineralisation, hosted within faultrelated veins and stringers associated with iron and silica alteration assemblages. Higher zinc grades are encountered in these willemite-enriched zones, lying along the western and northern edges of the drilled resource. The results of these holes are summarised in Table 11.5.1_1. (4.47% Zn from 16-26m)
At Foundary South, no sulphides other than trace amounts of disseminated sphalerite were intersected. All drillholes intersected iron-stained carbonate rocks with disseminated and narrow vein-hosted willemite/smithsonite accumulations. The best intersections are presented in Table 11.5.1_2.

KAWANGA HISTORY
• Rhokana Corporation Limited conducted a regional exploration programme, including the Lumwana West area in the early 1930’s. The company produced reconnaissance maps covering the area at a scale of 1:126,720. Geological mapping was conducted by Mwinilunga Mines from 1953 to 1961; and by AGIP from the mid-1970’s to the late 1980’s. AGIP used airborne magnetic-radiometric surveys, stream sediment sampling, mapping and core drilling (Coats, 2001). Maps of various scales were generated by AGIP (from 1:250,000 to 1:50), as part of an exploration programme for radioactive (especially uranium) minerals.

Maps of various scales were generated by AGIP (from 1:250,000 to 1:50), as part of an exploration programme for radioactive (especially uranium) minerals.
• AGIP discovered the Kawanga uranium deposit during this campaign. AGIP drilling intersected uranium mineralisation at one or more layers, each up to several metres thick, over a strike length of approximately 1 km. A total of 302 rotary and diamond drillholes were drilled to evaluate and delineate the uranium mineralisation, though 51 drillholes did not intersect mineralised zones (AGIP, 1975).
• The deposit consists of lenses of mineralisation with an estimated uranium content of approximately 2,000 tonnes, according to J.S. Coats (2001). A grade has not been established in accordance to an acceptable mining code. Any extrapolation of this figure must be treated with extreme caution. Snowden has not reviewed this historical estimate. Estimating a grade for the Kawanga uranium deposit will be a priority for management.
• AGIP divided the area into the Basement Complex unconformably overlain by Katanga metasediments.The Basement Complex comprised granites, migmatitic gneisses and schists intruded by pegamtites and amphibolites. Belts of mica-schists in the Basement Complex were referred to as a sheared facies.
• Radioactive anomalies were discovered at a number of locations within the Basement Complex and in the overlying Lower Roan Group. Uranium was found in traces of autunite and thorium-free pitchblende in quartz-kyanite-mica-chlorite-schists underlying a quartzite marker horizon, and in fractures (Meneghel, 1979 and 1984).
• AGIP formed a JV with Compagnie Générale Des Matières Nucléaires (COGEMA) in the late 1970’s. From 1980 to 1986, the JV carried out extensive exploration for uranium in the Domes Region of the North-Western Province following initial encouraging results by AGIP exploration groups (Cosi et al, 1992).

PRIVATISATION TRANSACTION SUMMARY SHEETS
PRIVATISATION TRANSACTION SUMMARY SHEETS
BACKGROUND:
The ZCCM assets which are the subject of this privatisation comprise the mining, concentrator and metal treatment assets of the Nchanga Divisions together with the Chingola Refractory Ore Dumps and Konkola Divisions including the Konkola Deep Mining Project (KDMP) and the Nampundwe Mine. During the Financial year 1998/99, the Nchanga Division was the largest producer of copper and cobalt in ZCCM with the ore sources including the Nchanga Open Pit and the Nchanga Underground Mine, which form part of the assets in question. Ore from all sources is treated at the Nchanga Concentrator.
At the time the GRZ embarked on the privatisation programme of the ZCCM assets, the company had been going through a critical stage in its operations mainly because of the high costs of production and over employment in these ZCCM Divisions. The ZCCM realised that there was an urgent need to inject fresh investment capital into ZCCM to avoid the possible collapse of the entire mining sector. There was need to rehabilitate the existing operations and development of the Konkola Deep Mining Project (KDMP), exploration drilling and evaluations on the Nchanga deposits both underground and open pit with a possibility of extending its life, and extensive evaluation of the Chingola Refractory Ore Dumps (CROs).
However, the ZCCM did not have access to the capital which was urgently required to rehabilitate and develop the assets. GRZ and ZCI, the two largest shareholders in the company, confirmed that they were not prepared to provide the requisite funding to allow such rehabilitation and capital investment to be undertaken by the company.

NKANA SMELTER, REFINERY AND ACID PLANT OPTION GRANTED TO ANGLO/KCM AND MCM)
ZCI had requested to manage and operate the Nkana Smelter and Refinery on a management contract for a period of 5 years from close. The first 3 years will be with an option to purchase, while the last 2 years will be with a right of first refusal should other bids be received.
The rationale for this request is premised o the fact that KCM would be the largest producer of copper in Zambia and that it would be necessary for them to control their smelting and refining route. During this period they will be evaluating the viability of introducing an alternative long term metal processing route.
The assets belonging to the Nkana Smelter, Acid Plant and Refinery have been incorporated into a wholly owned subsidiary of ZCCM (ZCCM SmelterCo Limited) which being managed by Anglo American Plc.
MCM has been granted a second option on SmelterCo.
b) Option Price/Commercial terms
An option price of US$ 7 million has been agreed.
Further, all the SmelterCo loans/liabilities as at the option date would be assumed by the buyer.
c) Funding of operations
The British Government has given GRZ a grant of US$ 81 million for onward lending to SmelterCo for capital and operating expenditure.

3.5.1.3 Production and Mine Life
The reserves report, updated to August 2005, accounts for only 20.5 Mt of ore reserves. In addition, the total measured, indicated and inferred in situ ore resources of the existing Konkola and the new Konkola Deep Mine sum up to approximately 235 Mt. However, the 17 Mt of inferred resources associated with the existing mine are likely to be inaccessible leaving a practical total of 214 Mt of reserves and mineable resources (allowing for losses and dilution). According to the IMC projections the total ore production until 2035 will be approximately 164 Mt. The remaining 50 Mt ore would allow for another 8 years of mine operation at 6 Mtpa capacity. However, it has to be noted that the mineable resources include approximately 78 Mt of inferred resources. Assuming that all of the remaining 50 Mt of mineable resources at the end of the plan are inferred, the mine plan to 2035 already includes approximately 28 Mt of the production from inferred resources.

According to the IMC projections the total ore production until 2035 will be approximately 164 Mt. The remaining 50 Mt ore would allow for another 8 years of mine operation at 6 Mtpa capacity. However, it has to be noted that the mineable resources include approximately 78 Mt of inferred resources. Assuming that all of the remaining 50 Mt of mineable resources at the end of the plan are inferred, the mine plan to 2035 already includes approximately 28 Mt of the production from inferred resources.

3.3.1 Mining Facilities
The underground mine had two shaft sections, 1 shaft and 3 shaft. These areas were linked but run as separate production units. No 1 Shaft was the first to be sunk and is to a depth of 1,070 m, and 3 shaft is to a depth of 600 m. Both shafts were equipped for hoisting ore and waste plus personnel and materials. The rock hoisting capacity of each shaft was approximately 2.15 Mtpa. However, shaft capacity was not a production constraint as ore generation was significantly below these levels.
Haulage levels were being mined at 60 m vertical spacing, although previously these had been at greater intervals. The lowest haulage level was the 950 m haulage. The mining methods in use were sub-level open stoping (SLOS), and longitudinal room and pillar. SLOS was mechanised, but lack of development in the years prior to 2005 had limited the number of stopes available for production. The mining equipment available was in good condition and well maintained.
Konkola was and remains an extremely wet mine with pumping requirements of around 240,000 m3 of water per day to enable stoping operations to be maintained in a dewatered state. Water control consists of a series of settlers and sumps on various levels. Total installed pumping capacity was reported to be 480,000 m3 per day. Water control within the mine is good and the mining conditions are generally dry.

Mining
The existing No.1 shaft and No.3 shaft systems at Konkola have been managed as separate mines. Underground haulage connections between the two mines were developed mainly for cross tramming and dewatering purposes. The mine pumps about 280 000 m3 of water per day to the surface. All water is pumped out via No 1 Shaft.
Both shafts are used for servicing and for hoisting ore and waste. The underground ore arising from Konkola is treated in the Konkola concentrator situated close to the No.1 shaft
Concentrator
The ore from the mine is treated at the Konkola concentrator situated close to the No.1 shaft. The No.1 shaft material comes directly into the plant while the 3 shaft materials is trucked to the plant. The concentrator has the capacity to process 2.4 million tonnes per annum (about 6500 tpd)

3.3.2 Process Plant
The plant dates from 1958 and, in August 2005, had a capacity of 2.4 Mtpa. No 1 shaft is close to the concentrator and the ore is delivered by conveyor belt. No 3 shaft is some 3 km distant and ore is delivered by 30 t and 50 t truck.
Ore grade was typically 3.5 to 3.8% from No 1 shaft and 2.5 to 2.8% from No 3 shaft. The ore has an average grade of circa 3% copper. The copper is broadly described as being either acid insoluble (predominantly highgrade sulphide minerals) or acid soluble (essentially oxide copper although small amounts of bornite and chalcocite are also soluble in acid). The flotation recovery of the acid insoluble minerals is high at above 90 %,whereas the recovery of the acid soluble fraction is at circa 40% range. Gangue material is predominantly silica with some dolomite.
3.3.2.1 Concentrator
The processing route entailed washing, two stages of crushing, milling, flotation of sulphide mineral and flotation of oxide mineral and finally dewatering.The first stage of processing was washing to remove fines from the minus 150 mm ore. There were two washing plants. The South washing plant took ore from No 1 shaft and the North washing plant took ore from No 3 shaft.
The milling circuit was designed to produce a feed to the flotation circuit with a size of 85% passing 74 micron. The milling circuit consisted of nine Hardinge ball mills and two Vecor ball mills.The main flotation circuit consisted of three banks of primary sulphide rougher cells, secondary sulphide rougher cells and oxide rougher cells. The slimes flotation circuit consisted of one bank of cells. The concentrate was cleaned in a column cell and then re-cleaned whilst the tailings were pumped to two banks of cells for scavenging.
Dewatering of concentrate was by thickening, filtration and thermal drying. There were four thickeners followed by four drum filters. Thermal drying was done in two coal fired rotary dryers.

3.4.3.2 New 3 Mtpa Concentrator
The updated 2005 feasibility study envisages a new concentrator being built adjacent to the new No 4 shaft. The new plant would consist of a 3 Mtpa module comprising a mill feed silo, SAG and ball milling and large flotation cells. This was planned to allow the plant to treat a total of 6 Mtpa ore by 2008. Concentrate from both the new and the old expanded facilities would be thickened using the existing thickeners and then filtered in a new filter plant to be sited near the current concentrate shed. The filtered concentrate would be placed in covered storage prior to despatch by rail or road.

3.3.3 Tailings Disposal
The Konkola Tailings were and still are disposed of at the Lubengele Tailings dam, situated approximately 4 km north of the process plant. The tailings facility was constructed in 1964 in a natural valley into which 4 streams flow.
In August 2005 the tailings generated within the plant were piped to the tailings dam through one of two pipes which operate alternately. The dam consisted of two separate ponds within the dam area through which the water passed until coming to the surface decant point where the water was discharged via a penstock into the Lubengele Stream, which ultimately joins the Kafue River. Drainage from the embankment was collected by filter drains. A spillway was due to be constructed to accommodate emergency runoff.
Erosion of the wall was occurring due to the angle of the dam wall. The erosion gullies that formed were backfilled every two years with course tailings or rockfill. In order to prevent erosion from occurring, vegetation of the walls was being undertaken
3.4.4 Tailings Disposal
At 6 Mtpa the capacity of the Lubengele dam provides in excess of eighty days residence time. This is more than sufficient for natural settlement of the fine material in the increased volumes of waste water to be discharged from the expanded process plant.
However, the wall of the dam has to be raised by approximately 10 metres to provide the necessary capacity for tailings discharge up to 2031 and the existing penstock will be replaced with a spillway. The wall design is based on a 1 in 100 year, 24 hour floodline.

The Konkola North Copper Project is located within the greater Konkola area of the Zambian Copperbelt and consists of a single large scale mining licence covering an area of approximately 44 square kilometres. The development of this project is a high priority for the Company. In the opinion of RSG Global, the greater Konkola area represents one of the largest undeveloped copper resources in the world. Pursuant to a drilling program in excess of 47,000 metres, TEAL has identified inferred mineral resources of 78.8 million tonnes at 2.14% copper. This resource is contained within only the east and south limb areas of the project. Historic records and more recently drilled results relating to other areas of the project indicate a further inferred mineral resource of approximately 107 million tonnes at grades of 2.30% and 63 million tonnes at grades of 3.88% copper. See "Zambia – Copper Projects – Konkola North Copper Project – Mineral Resources". At the south limb, TEAL intends to focus initially on the development of a high-grade region of the deposit and re-equipping of the existing infrastructure, which includes a 423 metre vertical shaft, two ventilation shafts and three ore haulage levels. At the east limb, the Company is considering the sinking of a decline shaft to access the mineralization. The Konkola North Copper Project is adjacent to the existing Konkola Mine, owned by Konkola Copper Mines plc, which has existing operational mining infrastructure. The Konkola North Copper Project is subject to a buy-in right of up to 20% (including a 5% carried interest) by ZCCM Investments Holdings plc ("ZCCM-IH"), a company controlled by the Zambian Government.

Rothschild & Sons Limited on synergies with KCM past 2017
- Use of KCM Shaft No 3 for Konkola North
- Nchanga Tailings Leach Plant in relation to Mwambashi B
Konkola North was sold separately at the time of the privatisation of ZCCM and at the Relevant Date was owned by Teal Exploration and Mining. This company was floated on the Toronto Stock Exchange shortly afterwards.
Konkola North contains the Northern extension of the Konkola ore body. Prior to 1959 this deposit was exploited and there is still a shaft (No.2 Shaft) in existence. However,recommencement of production will require extensive development. In its report, IMCL has indicated that it may be cost efficient to develop this asset using a portion of KCM s existing Konkola infrastructure and, specifically, to use the No.3 Shaft once this becomes surplus to requirements following KDMPs development. If this approach were adopted then KCM could extract some of the economic value through:
- some kind of arrangement involving payment/royalty, NPI or access charge as consideration for the use of its assets; or
- a full or partial (joint venture) acquisition of the deposit which would allow it to extract some of the synergies.
- some kind of arrangement involving payment/royalty, NPI or access charge as consideration for the use of its assets; or
- a full or partial (joint venture) acquisition of the deposit which would allow it to extract some of the synergies.
However, we do not believe that even an aggressive buyer of KCM would have been likely to have placed any material value on this possibility at the Relevant Date because:
- at the time, any development of Konkola North remained uncertain;
- based upon the Listing Particulars of Teal (which were published shortly after the Relevant Date) there is no evidence to suggest that Teal was considering a development that would rely in any material way on KCM s infrastructure;
- IMCL s work has indicated that the development schedule for Konkola means that the shaft would only become available post 2017. We therefore suspect that any NPV benefit to Teal from its use would be more than offset by the NPV loss of the delay in Konkola North s development (albeit it could be used in a subsequent phase); and, more generally,
- based upon the Listing Particulars of Teal (which were published shortly after the Relevant Date) there is no evidence to suggest that Teal was considering a development that would rely in any material way on KCM s infrastructure;
- IMCL s work has indicated that the development schedule for Konkola means that the shaft would only become available post 2017. We therefore suspect that any NPV benefit to Teal from its use would be more than offset by the NPV loss of the delay in Konkola North s development (albeit it could be used in a subsequent phase); and, more generally,
- arrangements of this type, while often considered in the mining industry, are usually difficult to agree and it is quite common, even when considerable demonstrable synergies are available, for the value not to be realised.
Separately, Teal own the majority of the small Mwambashi B deposit. IMCL believes exploitation of this might be more logical if the ore was processed through the Nchanga Tailings Leach Plant. In its Listing Particulars Teal specifically identified the availability of nearby processing facilities as a means of reducing the capital expenditure of a development. We are not aware that at the Relevant Date any significant discussions had taken place regarding this approach and, furthermore, Teal had yet to conduct a Feasibility Study. Given these considerations and the project s relatively small scale we doubt a buyer would have attributed material value to the possibility of extracting value through third party processing of Mwambishi B material.

Government is setting up a railway line from neighboring Angola via Mwinilunga district to Chingola on the Copperbelt Province. North-western Province Minister Kenneth Chipungu who confirmed the development in Solwezi today said the move seeks to ease the pressure on the road network.Mr. Chipungu observed that the roads were being damaged due to heavy equipment ferried by trucks. The minister said the railway will facilitate the transportation of copper by rail to Lobito bay in Angola. He said government through the Ministry of Communications and Transport is negotiating with a possible financier of the project.

190: Luamata (First Quantum)
Area
The Shaba-type Luamata Cu-Co(-Ni) deposit (11°50'S, 24°28'E) is located in a tectonic slice of Katangan Roan Supergroup (Mines Group) sedimentary rocks, surrounded by younger Kundelungu Supergroup lithologies in the external fold and thrust belt of the Lufilian Arc. Luamata is a classic central African copper clearing in dense woodland, visible as a tonal botanical anomaly on Landsat imagery. Supergene Cu-Co mineralization (especially malachite and subordinate chalcocite, digenite, covellite, and copper and cobalt oxides) and, probably hypogene, bornite, and chalcopyrite are hosted by altered, but essentially unmetamorphosed, moderately dipping, dolostones and dolomitic shales. Alteration products include talcose dolomite, sericite rocks and intense silicification and brecciation. Friable yellow shale is best mineralized with cobalt (up to 0.43 wt%), whereas, highest copper grades occur in brecciated, silicified shale (up to 13.5 wt% CuO). Soil copper and cobalt contents are up to 2.2 and 0.6 wt%, respectively. A newly identified nickel zone (where soil contents exceed 0.1 wt% Ni) fringes the Cu-Co deposit. Polymictic, matrix-supported breccias with a calcareous matrix that underlie the Cu-Co deposit are interpreted to be fluidization breccias related to thrust tectonics and the emplacement of the Mines Group slice. Although small compared to the Kolwezi district Shaba deposits in the Democratic Republic of the Congo, Luamata exhibits all the classic features of an ore deposit type (with low calcite contents), whose high metal concentrations could potentially be very profitably exploited by low-cost opencast mining and hydrometallurgical recovery methods.

192: Central Luangwa Valley Uranium-Coal Project (AFR)
The Central Luangwa Valley Project comprises two areas, Munyamadzi and Kakumbi, and is part of the Exploration Agreement with Albidon Limited. The two blocks cover portions of two of Albidon’s Prospecting Licences (Munyamadzi covers part of PLLS.260 Chilonga, Kakumbi covers part of PLLS.246 Kamoto), and have a combined area of 10,085 sq km (Figure 10).
The tenements were pegged by Albidon on the basis that they contain Karoo sediments, and also because they contain basement rocks which may be prospective for base metals. The areas covered by the Exploration Agreement, Munyamadzi and Kakumbi are those parts of the tenements that contain the Karoo sediments which are prospective for uranium, coal and coal-bed methane.
Little previous exploration for uranium has been documented for this area So the Company therefore plans to generate targets on the basis of geological interpretation where this demonstrates the presence of target Karoo sediments above uranium-rich basement rocks and faults which link the two. Any such areas defined will be evaluated with field reconnaissance and spectrometer traverses.

The Northern Luangwa Valley Project comprises two Prospecting Licences granted to African Energy and covering a total area of 17,915 sq km. The project is situated at the northern end of the Luangwa Valley in northeast Zambia, extending as far as the international border with Malawi (Figure 10). Access to the eastern side of this project is generally good, with a major road running the length of the project, whereas access to the western side is generally very poor. The tenements were pegged to cover the northern extension of the Karoo sediments in the Luangwa Valley, 30km along strike from the Kayelekera deposit in northern Malawi, where Paladin Resources have outlined a resource containing over 15,000t of U3O8.
Previous exploration has defined a significant multi-point regional radiometric anomaly, over an area of 400 sq km; along with a number of smaller, lower level anomalies. The Company has evaluated this area through an airborne radiometric survey. This has identified six anomalies which require more detailed ground follow-up mapping in mid-2007and, if warranted, reconnaissance drilling

Based on previous exploration one significant radiometric anomaly has been identified at the Myvuwe River prospect. This has been evaluated for its uranium potential through a detailed airborne radiometric survey. Results from this have confirmed this anomaly and identified an additional area of uranium anomalism (Figure 9). These will be evaluated by field mapping and, if warranted, reconnaissance drill testing in 2007.
In addition to the uranium potential, coal bearing horizons up to 60-120m thick have been noted in the Luano Valley, suggesting good CBM potential in the region. A program to evaluate this potential will be implemented in 2007.

The rocks of Karoo Supergroup includes tillites, glacial varves, coal, mudstones, sandstones,marls, grits, conglomerates and basalt. The Supergroup is divided into Lower and Upper Karoo, the former essentially comprise fine clastics and the latter coarse clastics and basalt. They range in age from 300Ma to 150Ma. Major outcrops occur in rift valleys and in western Zambia. The Victoria Falls at Livingstone is floored by basalt which is spasmodically distributed throughout western Zambia beneath the sand cover. Coal is the principal mineral of economic significance in the Lower Karoo while uranium is preferentially distributed in the Upper Karoo.

The site for the proposed decommissioning and closure lies to the immediate west of Luanshya town, and extends west towards the Kafue River for about 11 kilometers, covering an area of approximately 800 hectares. The project will involve flooding the underground mine workings to a level between 5 and 10 metres below ground surface, and rehabilitation of the area. The flooding of the mine will occur through natural recharge of the surrounding aquifers, which in turn will be recharged by rains.
ECZ has approved the project subject to the following conditions:
1. The developer shall comply with the Waste Management, Hazardous Waste Management, and Water Pollution Control Regulations.
2. The plant area - Baluba Road which passes through residential areas shall be re-routed to avoid populated areas.
3. All Polychlorinated biphenyls (PCB) equipment containing oils should be drained and all the oil removed and stored in ECZ approved containers.
4. All equipment in underground working environment that contain oils or other substance with a potential to pollute shall be removed from underground and disposed of on the surface at sites approved by ECZ approved sites.
5. All caving areas shall have warning signs to prevent unauthorised access by members of the public

It is disappointing to report that there has been no further progress in resolving the dispute relating to exploration licence PLLS 239 in Zambia. Weatherly is still awaiting a date to be set for the High Court to hear the matter. In the meantime, the Zambian Government has applied to the courts to have Luanshya Copper Mines Limited joined with the government as co¬defendants. It is anticipated that there will be some resolution to the matter in the coming year. This dispute does not affect Weatherly's nearby PLLS 252 license or its ability to treat the tailings on license PLLS 240 for the recovery of copper

Mine Plan
The Development Case mine plan envisages that the Malundwe and Chimiwungo deposits, which are 7km apart, will be mined sequentially by open-pit mining methods. The ore bodies are 95% sulphide (with only 5% oxide) and very consistent, so large-scale bulk-mining methods are being employed utilizing equipment that includes a total of 27 x 240 tonne capacity diesel-electric drive hybrid haulage trucks and 7 x 518 tonne diesel and electric loaders (excavators and face shovels).

Sulphide ore will be processed on-site by conventional crushing, grinding and flotation to produce copper concentrates for shipment to offsite smelters. Metallurgical test work indicates recoveries of greater than 95% copper, producing average concentrate grades of 43.3% Cu for Malundwe and 29.5% Cu for Chimiwungo. The flotation plant has a design capacity to treat at least 20 million tonnes per year of ore and will, in the first 6 year period, produce in concentrate 172,000 tonnes of copper metal per year (380 million lbs per year).
Life of mine production will average 156,000 tonnes of copper metal per year (340 million lbs year) based on the 20 million tonnes per year throughput
Concentrate Offtake
During 2007 Equinox signed off take contracts for 100% of its copper concentrate production for the first 5 years of the mine life.
During 2007 Equinox signed off take contracts for 100% of its copper concentrate production for the first 5 years of the mine life.
The first offtake contract is with Chambishi Copper Smelter Limited, a joint venture between China Nonferrous Metal Mining (Group) Co. Ltd. and Yunnan Copper Industry (Group) Co. Ltd. to build a new copper smelter at the Chambishi mine on the Zambian Copperbelt. Equinox will supply this new smelter in a 5-year ‘take and pay' contract to commence from Lumwana commissioning, with annual commitments to Chambishi of 100,000 tonnes of copper contained in concentrates or approximately 230,000 tonnes of Lumwana concentrates. While the Chambishi smelter will probably not commission until early 2009, the ‘take & pay' nature of the offtake contract means that Lumwana concentrate will be delivered to the smelter from mine commissioning.
Equinox also signed concentrate sale and purchase agreements with Mopani Copper Mines Plc and Glencore International AG (‘Glencore') for a total minimum contractual ‘take and pay' tonnage of 53,000 tonnes of copper contained in concentrates or approximately 120,000 tonnes of Lumwana concentrates annually.
The agreements also grant Glencore a first option right to process further additional annual quantities of Lumwana copper concentrates in excess of the above commitments

Flow sheet:
Trucks from the mine will tip directly into a 400 t capacity ROM dump hopper. The ROM pad will accept ore that cannot be directly dumped into the crusher feed hopper. The primary gyratory crusher will be used to crush the ROM ore from a nominal top size of 1 500 mm to less than 200 mm. Oversize material will be deposited on the ROM pad to be further broken by a mobile rock breaker. Crusher product is then conveyed via a 4.5 km overland conveyor to a conical crushed ore stockpile with 16 hours live capacity.
Ore is to be reclaimed via apron feeders onto a conveyor belt providing direct feed, at a rate of approximately 2 500 t/h, into the 38 ft x 18 ft SAG mill. The SAG mill trommel undersize discharges into a hopper and is pumped to conventional hydrocyclones,
operating in closed circuit with a 26 ft x 40 ft ball mill. The hydrocyclone overflow (P80 of 280 ?m) reports to flotation, whilst the underflow returns to the ball mill.
operating in closed circuit with a 26 ft x 40 ft ball mill. The hydrocyclone overflow (P80 of 280 ?m) reports to flotation, whilst the underflow returns to the ball mill.
The flotation plant consists of two parallel trains of rougher/scavenger cells. The rougher/scavenger concentrate reports to the regrind circuit to further liberate the copper minerals. Following regrinding, the concentrate is cleaned in a conventional cleaner/recleaner circuit to reach final concentrate grade. Final concentrate grades of approximately 44% and 29% copper are expected from Malundwe and Chimiwungo respectively.
The concentrate will be dewatered in a circuit consisting of high-rate thickening followed by pressure filtration to produce a filter cake suitable for transportation. The concentrate will be stored in a 7 day capacity storage shed from which it will be subsequently loaded onto trucks and transported to market for smelting and refining. Flotation tailings will be thickened and pumped to the tailings dam.
The majority of the Copper Plant water will be recovered and recycled from the thickener overflows and tailings dam return water. Fresh make-up water will be supplied from a river water dam as required.

220: U Process Plant - Lumwana
The uranium ore is proposed to be processed through the Uranium Plant at a rate of 1Mt/a. In the first five years the Uranium Plant is estimated to produce 2.0 Mlb/a of uranium oxide (U3O8) and 12 800 t/a of copper concentrate. Uranium recovery to uranium oxide is estimated to be 93.1% and copper recovery to the Uranium Plant copper concentrate is estimated to be 80.1%.
Flow sheet:
Ore is recovered from high grade and average grade stockpiles at an average blended grade of 0.11% U3O8. The circuit is designed for a maximum head grade of 1.31% Cu and 0.25% U3O8. The ROM ore is crushed and ground to the final size of P80 280 ?m in a jaw crusher and a wet single stage SAG mill circuit. Copper sulfides are removed as a copper concentrate in a flotation circuit prior to the extraction of the uranium. The copperrougher concentrate is reground to 20 ?m to liberate copper and gangue minerals for further flotation and copper concentrate up-grading. Up to 100 tonnes per day of copper concentrate is filtered, bagged and loaded into shipping containers for transport to offsite smelters.
The thickened flotation tailings is leached with sulphuric acid at pH 1.8, and an oxidant (pyrolusite). The leach discharge slurry is dewatered and washed using a horizontal belt filter. The washed filter cake (solids) reports to the tailings neutralisation circuit prior to being pumped to the UTSF at a pH of 9.5 and 50 percent solids. The filtrate (PLS) is clarified and stored in the PLS pond, prior to being pumped to the SX circuit.The SX circuit comprises 4 extract, 2 scrub, 4 strip and one regeneration stage. Uranium is extracted from the PLS solution using an organic reagent. The scrubbing stage is used to remove any build-up of impurities on the organic reagent. The organic reagent is periodically regenerated using sodium hydroxide/sodium carbonate for optimal performance. The uranium is stripped from the organic (into solution) using ammonia and reports to the uranium precipitation circuit as “Strip Solution”. The barren solution (raffinate) is re-used in the circuit to minimise fresh water usage whilst a bleed stream (raffinate bleed) reports to the tailings neutralisation circuit. The uranium in the Strip Solution is precipitated using ammonia. A scrubber is used to capture fugitive ammonia emissions, with excess ammonia recovered and re-used in the process using a lime boil circuit.
The precipitate is dewatered and calcined to form uranium oxide (yellowcake at 99.7% U3O8). The yellowcake will be packaged and sealed in United Nations certified drums, samples taken for analysis, weighed and labelled prior to being stored in sea containers, ready for shipment.Each shipping container stores approximately 45 drums (16 t to 18 t) and will be transported under IAEA guidelines at a frequency of once per week to a shipping port. The shipping container will subsequently be loaded onto a ship and exported to a uranium conversion facility, consistent with the Nuclear Non-Proliferation Treaty (“NPT”).

HISTORY
The Rhodesian Congo Border Concession investigated the area during the 1920s and 1930s, where they claimed the Chifumba and Jumbo copper prospects. Primary copper mineralisation was defined by diamond drilling and shaft sinking at Chifumbo, wheras at Jumbo, a reported 10,000 t of ore with a mean grade of 3.5% Cu was produced from 300m of underground development. The company concluded the mineralisation terminated against a fault and so stopped work.

Primary copper mineralisation was defined by diamond drilling and shaft sinking at Chifumbo, wheras at Jumbo, a reported 10,000 t of ore with a mean grade of 3.5% Cu was produced from 300m of underground development. The company concluded the mineralisation terminated against a fault and so stopped work.
Between 1958 and 1961, Chartered Exploration defined a number of geochemical anomalies including the Kaungashi, Buffalo and Wambo Prospects.At Kaungashi, the exploration outlined lead-zinc and copper-zinc soil anomalies over a substantial strike length. Pitting and wagon drilling revealed that the mineralisation was most likely associated with a series of syenite intrusions, with hydrothermal alteration and mineralisation of surrounding
breccias in phyllites and limestones. Two prospecting shafts were sunk and a limited number of diamond drill holes completed which confirmed that zinc mineralisation was associated with syenite contacts.
At the Buffalo copper prospect, follow-up work to the Chartered Exploration regional prospecting was undertaken by Zamex, who drilled four diamond drillholes in 1961, yielding a number of significant drill intercepts, including one of 28.0m which averaged 1.1% Cu.
At the Wambo Prospect, Chartered Exploration outlined base metal mineralisation (Cu, Pb, Zn) and follow-up work culminated in the drilling of three diamond drillholes by Zamanglo in 1970. These holes intersected significant zinc mineralisation associated with graphitic dolomite breccias, including one intersection of 119.0m which averaged 1.2% Zn. Between 1994 and 1996, Phelps Dodge undertook soil sampling, mapping and chip sampling over the Buffalo, Jumbo and Kaungashi prospects. This work was preliminary, unsystematic and inconclusive,although high grades of copper and zinc were found in the initial rock sampling.
In 2000, Avmin repeated some of the earlier work through a combination of geochemical and geophysical surveys, geological mapping, surface sampling and trenching. One trench at the Kuanhashi prospect yielded a 9m intersection with mean grades of 1.9% Cu and 2.2% Zn. This work was followed up by 4,750m of air core drilling to identify the host lithologies. Two main anomalous zones were identified from the drilling; a southern zone principally developed over a diamictite (Grand Conglomerat) and a northern mineralised zone, possibly structurally controlled, cross cutting the lithologies. Better intersections included 3.6% Zn over 12m and 1.4% Cu over 4m.
In 2001, a 5 hole diamond drill programme, comprising 1,194m, was completed at both the Kuangashi and Buffalo prospects. Although no economic intersections were obtained, stratabound mineralisation associated with the Grand Conglomerat showed the entire horizon to be highly anomalous for both Cu and Zn. One of the holes yielded an uncorrected 90m intersection with average grades of 0.7% Zn and 0.3% Cu. Higher grade intersections include 1.72m at 2.3% Cu. The mineralisation comprised chalcopyrite associated with veins, veinlets, stockworks and small breccia zones filled by carbonate, heamatite and quartz demonstrating an epigenetic component to the mineralisation.

Coal reserves in the Zambezi Basin: Maamba
Zambia's single coal mine at Maamba exploits the near out-crop areas of thick coal development in part of the Siankondobo coalfield, north of Lake Kariba. Major faults divide the coalfield into two main structural units known as the Kazinze and Izuma basins. In the Izuma Basin, single thick seam is developed, while in Kazinze, the seam is split into two components by a laterally persistent sandstone band.
The Maamba Colliery was originally designed to produce over one million tonnes of saleable coal annually. Its actual capacity has never approached this design target and has actually dropped from about 750,000 to 350,000 tonnes. Zambia Consolidated Copper Mines (ZCCM) Nkana and NCZ are Maamba Colliery's largest customers. Most of the coal from Maamba is pyritic inorganic sulphur and only about 40 percent has inherent sulphur that cannot be completely washed.

232: Mapatizya Amethyst (Nyendwa MayfairMining)
AREA
The Mapatizya Amethyst concessions encompass over 600 hectares located in the Kalomo District of Zambia, approximately 115 kilometres from Kalomo Town and 415 kilometres from Kafue. Mapatizya is the principal amethyst mining area in Zambia. Access to the area is possible throughout the dry season by a feeder road branching off seven kilometres before Kalomo. The road is maintained by the Government and can accommodate heavy trucks. There is good infrastructure in the region and good road access to the concessions. Mayfair Mining's concessions surround the property of Kariba Minerals, which hosts the largest amethyst-producing mine in Zambia and one of the largest in the world
HISTORY
Limited work has been previously conducted on Mayfair Mining's Zambian licenses. Between 1960 and 1983, all of the licenses in the Mapatizya area were prospected by Northern Minerals, although no significant production was undertaken and in 1983, small scale trial production was undertaken by a private individual who later abandoned the licenses after producing approximately 30 tons of amethyst. Between 1992 and 2004, Mwaca Mining and Minerals took over the licenses and conducted exploration and small scale mining. Approximately 400 tons of amethyst was produced and sold.

GEOLOGY
Deposit type: Footwall Quartzite Hosted Mineralisation (Type 1b)
Copper mineralisation is hosted by quartzite in the footwall of the OS1 Member at the Chingola ‘B’, Mwambashi ‘B’ (Mwambashi Copper Project), Chibuluma, Fitula and Mimbula mines. The host units are located in fault bounded sub-basins to which the overlying shale has acted as an impermeable barrier and reductant for mineralised fluids. It has been postulated that hydrocarbons trapped in the arenaceous footwall sediments may also have acted as reductants that have controlled precipitation of sulphide minerals from mineralised fluids. Whilst having smaller resources than the ore shale deposits, typically several tens of millions tonnes, the grades are generally higher at 2.5% to 4% Cu, with varying Co grades.

Ndola prospect - 278km²
May 13, 2008
At the nearby Misundu target, the Company drilled three diamond drill holes and nine percussion drill holes for a total of almost 2000 metres, before drilling was suspended to await the results of the detailed geochemical survey and other surface surveys. Unexpectedly, the drilling intersected rocks which appear to belong to the Dipeta Formation, within a structurally complex zone. The Dipeta is part of the Upper Roan and is known to host significant copper deposits in neighbouring DRC.
Diamond drill hole NDE1 was drilled to a depth of 603m with wedged offsets to define the stratigraphic succession and to gain a better understanding of the structural complexity and mineralisation at Misundu. Mineralisation grading 1.1% copper was intersected in this hole at 58 vertical metres over a width of 7m and further drilling is planned.

HISTORY
Discovered in 1922, the Mkushi project deposits were first mined by underground workings, then developed as an open pit operation in the late 1960’s. The open pit ore was delivered to a conventional copper sulphide concentration plant which successfully produced a concentrate that was sold into the international markets. The majority of the process plant remains on site but it is considered too small to be of use in the future operations conceptualised by CGA. The operation closed due to the nationalisation of the Zambian copper industry in the 1970’s. Available archives indicate that the mine operated at a grade of approximately 1.5% Cu and that there is still abundant material of similar grade left in the ground. The local infrastructure in the Mkushi area is excellent and the brownfield site should allow project development permitting to be straightforward.

RESOURCE BASE - MOKAMBO CENTRAL 2008
Inferred 14.9Mt at 1.22% Cu Sulphide
STATUS - DORMANT
Following an evaluation of the NI 43-101 Report prepared by Coffey Mining on the sulphide mineral resource, and a verbal report from Coffey Mining on the oxide drilling program, the Board is of the opinion that the grade and the tonnage of the sulphide resource and oxide deposit will not support a mining operation and that further drilling will not significantly increase tonnage and grade. Results of the evaluation of the sulphide resource and the 43-101 report prepared by Coffey Mining have previously been reported on and Coffey Mining advise that “results of the mineral resource modeling have indicated that there will be insufficient tonnage and metal concentration and recoveries for the
project to be viable.” The Board has therefore decided to abandon the Mokambo project
HISTORY
• The Mokambo Property and adjoining concessions have had substantial exploration programs completed on them, since 1929.
• In 1970, a joint venture was established between the government of Zambia and the Socialist Republic of Romania to explore the area. Geomin (Romanian Foreign Trade Company for Mines, Oil and Geology – Bucharest), Romanian acquired Prospecting Licence (PL 51) and Exploration Licence (EL 3) and took control of the property. A program of 6 diamond drill holes was completed to fill in gaps from previous drill programs. Geological prospecting, hydrological and geotechnical drill surveys and several new trenches and pits were completed as part of this exploration program.
• An exploratory shaft was constructed in 1974 on the Mokambo Property to further test the largest concentration of sulphide copper mineralization found by drilling. It was sunk to 125 meters and was originally designed to have four levels (120, 190, 260 and 330 meters) as well as an ore storage and loading pocket. This would have given the shaft an ultimate depth of 430 meters. During the construction of the 120-meter level, water-laidened faults were encountered which eventually flooded the mine in February 1975. A new preliminary feasibility study was completed by Geomin in 1976 but Mindeco (co-owners of the Mokambo by now) disagreed with the economic data in the study. The flooded shaft-event, along with a continuing low copper price and political unrest between Romania and Zambia eventually shut the operation down and the project was abandoned in 1977 (Mambwe, 1985).
• In 1987, Paragon Mines Limited (a Canadian-based junior mining company) took on the project but before work commenced, all 4 directors were tragically killed in a motor vehicle accident outside of Lusaka, Zambia.
• The state-owned mining company ZCCM in 1992 carried out a feasibility study to try to amalgamate the Mokambo Property with the Mufulira Division of ZCCM but with impending privatization, the project was abandoned.
• Between 1994 and 1997 two Zambian individuals acquired the property in the hope of re-starting the Mokambo Property but had inadequate capital to re-open the operation. They finally scavenged all the equipment on the property, thereby eliminating the value-added assets.
• In 2005, North Western Plant Hire (NWPH) acquired the Mokambo Property by acquiring a Small-Scale Mining Licence (SML 235). Survey beacons (monuments) were installed and four trenches were hand dug in 2005. Only one of them was sampled due to lack of money for the project.
• ICS Copper Systems Ltd. (ICS) signed a Heads of Agreement with NWPH on July 24th 2006, followed by an Option Agreement dated August 10, 2006 to develop the Mokambo Property.

It was only possible to complete one diamond drill hole at Mokambo North, due to delays in obtaining environmental permitting. Past exploration in this area indicated a deposit of 3.8Mt at 1.7% copper, again pre-JORC standard. The 2008 drill hole (MND1) intersected a substantial zone of mineralisation including 15m at 2.44% copper at a depth of 162 vertical metres. The zone is open along strike and up and down dip. The mineralisation comprises largely malachite and chalcocite and while most is again hosted by the greywacke at the top of the Lower Road and in underlying quartzites, there is also significant mineralisation within a 'Middle Conglomerate' unit.

We made excellent progress during 2008 at Ndola and Mokambo generating a number of drill ready targets at Ndola and receiving promising results including 2.44% copper over 15m and 2.47% copper over 12m from our 3,000m diamond drilling programme at Mokambo. Parallel development of multiple exploration projects using our own funds, however, is no longer sustainable in today's climate. With Dutwa as our top priority for 2009, we are therefore seeking partners to earn interests in our more advanced copper projects at Mokambo, where we increased our interest to 87% at the end of 2008 and at Ndola where we retain a 100% interest in the property.
Since 1950, 22 diamond drill holes have been drilled within the Mokambo South licence area. Of these, 11 intersected significant copper mineralization, to depths of 1400m, over a strike length of 1km. From the results reported from these drill holes, the average grade of the mineralisation is 2.4% copper and the average thickness is about 4.6m, indicating a deposit of about 6 million tonnes with some 1.4 million tonnes of contained metal
HISTORY
• The area was investigated in the 1950s by a team from Mufulira and in the 1970s by Geomin, a Romanian group. Geomin estimated that the area holds a global endowment of some 41Mt grading 1.7% copper.
• Copper mineralisation has been intersected by drilling in the Mokambo South Zone over a strike length of at least 1km, to a maximum depth of 430m. Based on the results reported from these drill holes, the average grade is 2.4% copper over an average thickness of 4.6m indicating a deposit of 6Mt. Similarly, the Mokambo North Zone was estimated to contain at least 3.8Mt @ 1.7% copper.
• Since acquiring the project in August 2007, African Eagle has completed a 3000m drilling programme, soil geochemical surveys, geological mapping and geophysical surveys. It has also digitised maps and sections, and re-logged and re-assayed drill cores from the exploration carried out in the 1960s.

Mufulira Division and the Nkana Mines, Concentrator and Cobalt Plant
BACKGROUND:
The Mufulira copper deposit was discovered in 1922 and started operations in February 1930 as Mufulira Copper Mines Limited. However, the first concentrate was only produced in July 1933 due to a slow down in mining activity resulting from the economic depression, and the copper Smelter was commissioned in 1937 followed by the electrolytic copper refinery in 1952. The Mufulira Mine, Concentrator, Smelter and Refinery constituted what became to be known as Mufulira Division of the Zambia Consolidated Copper Mines Limited (ZCCM). The division=s copper production comes from one large underground mine. The combined ore reserves and underground resources at Mufulira total over 100 million tonnes. With this type of resources, it is clear that with some capital investment, the mine has a long life ahead of it. The Mufulira Concentrator has been in operation since 1933 and over the past 22 years leading to its privatisation, the Concentrator has not received adequate replacement capital for major investments such as secondary and tertiary crushers, conveyance systems, ball mills and waste-handling infrastructure, resulting in poor plant performance.

The Mufulira Smelter has a capacity to treat 420,000 tonnes of concentrate per annum but has only been treating around 300,000 tonnes per annum due to shortage of concentrates. In addition, operational constraints had arisen from inadequate funding for replacement of major capital elements such as converters, electrostatic precipitators, electric furnace transformers, steel structures, front-end loaders and dump trucks. There was an urgent need to rehabilitate the precipitators in order to improve recoveries as well as reduce environmental dust pollution. Therefore, there was an urgent need to inject sufficient capital into the Mufulira Smelter in order to revitalise operations and improve efficiencies.
Mufulira Division was by 1996 a high cost and loss making division of ZCCM and facing a possible closure. The division was starved of cash for investment and was experiencing very high costs of social assets/town services.

Falcon carried out a programme of geophysical prospecting, identified a series of anomalies which were subsequently confirmed to be mineralised and reported an “in situ resource” of some 100,000 t at 4.5% Cu. Falcon,however, considered this to be too small and suspended operations.
In 1956, a pilot scale plant was brought in to conduct metallurgical test work. Reportedly, some 2,300 t of copper were recovered from some 70,000 t of ore milled, equating to a recovered grade of 3.5% Cu. Operations were suspended due to low copper prices until 1966, when L.G. Nichols obtained an option over the property. Two additional mineralised zones were located using geophysics and subsequent diamond drilling showed the deposits could be worked profitably by open pit methods.Financial difficulties, however, precluded Nichols from developing the property.
In 1968, Mkushi Copper Mines together with an Italian Mining company, Miniera di Fragne Chialamberto, began open pit mining at Munshiwemba. The pit reached a depth of 30m and yielded 2.2 Mt of ore at 1.0% Cu until operations ceased in 1975.
Work by AER, since it acquired Mkushi in 1998, has included Landsat and aeromagnetic interpretation, soil sampling, rock chip sampling and geological mapping.The soil sampling programme covers most of the licence area. At the Coloquo prospect, the sampling defined a consistent copper anomaly of greater than 100 ppm over 500m long by 130m wide, with some low order zinc anomalism peripheral to the main anomaly. At the Mtugu Prospect, infill soil sampling returned assays up to 305 ppm Cu, 72 ppm Zn and 30 ppm Pb, although no consistent anomalies were defined. Limited rock chip sampling undertaken at both the Mtuga and Coloquo prospects returned values up to 14 g/t Au, and samples of tailings returned values of up to 0.48 g/t Au, indicating a potential coppergold association.

Reclamation of TD8 and TD10 by SMLZ
The Government has signed a $600 million agreement with China Non-Ferrous Metals Limited (CNMC) for the extraction of copper from the Mufulira Tailings dams to breathe economic life into the liability that was left over during the privatisation of the Zambia Consolidated Copper Mines-Investment Holdings (ZCCM-IH) assets.
ZCCM-IH board chairperson Alfred Lungu and CNMC chairperson Tao Xinghu signed the agreement at the Ministry of Mines in Lusaka that will see tailings dams eight and 10 reprocessed while the environment would be protected.
CNMC is the parent company of Sino Metals Leach Zambia (SMLZ) limited which will run the Mufulira Tailings project but this will be dependant on the results of the feasibility studies to be conducted at a cost of $5 million.
Mr Tao said of the over US$600 million to be invested by CNMC through its subsidiary, SMLZ.

The Kaonde
The Kaonde People can be found in Solwezi, Kasempa and Chizera districts of North Western Province and in Kaoma in the Western province. The Kaonde like the Lunda are the descendants of the famous Luba-Lunda Empire of Zaire. The Kaonde were among the first Zambian tribes to carry out the mining of copper and archaeological evidence at the Kansanshi Mine in Solwezi dating back to the iron age period proves this.

Mulofwe Dome Prospects:

52nd Minesite Presentation May 2008 (slides 9-12)
History:
Mineralisation in the Mulofwe Dome area was first documented in 1912 with the discovery of the Pala-Darg bismuth prospect. Between 1914 and 1934, 4.7t of bismuth was mined from the prospect at average grades between 2.63% and 4% Bi and up to 3oz/t Au. During this time other prospects within the dome, including Kyembe, Kaunga, Shapola, Somerset and Devonshire, were assessed although no record of this work is currently available.
Limited exploration by Charteredex during the early 1960’s resulted in an estimation of remaining “ore reserves” at Pala-Darg of 357t averaging 2.63% Bi. No gold exploration appears to have been conducted.
Between 1983 and 1985, rock chip sampling by Zimco Limited returned grades up to 50g/t Au from the Kaunga Prospect; 50g/t Au and 10,000ppm combined copper, tungsten and bismuth at the Kyebwe Prospect; 7g/t to 15g/t Au associated with anomalous copper, nickel and bismuth at Pala-Darg, 4g/t to 20g/t Au from the Shapola Prospects; and 10g/t Au and 8,000ppm Cu from Devonshire.Ground based magnetic, radiometric and electrical geophysical surveys were completed at Kyebwe, Darg and Kaunga 1 with limited effectiveness. Trenching and pitting at various prospects returned grades up to 0.5m averaging 15g/t Au at Kaunga 1, 0.3m averaging 8.75g/t Au at Devonshire and 0.5m averaging 22.5g/t Au at Pala-Darg.
Systematic rock chip sampling of veins illustrated a positive correlation between tungsten, gold, copper and niobium mineralisation with maximum values greater than 10,000ppm tungsten, 3.25ppm gold, 1000ppm to 2000ppm copper and approximately 1000ppm niobium. An 11 hole drill programme to test the ‘A’ tungsten anomaly returned negative results, however no gold analyses are reported. No further exploration is documented.

RESOURCE BASE
1.22Mt at 12% P2O5
The Mumbwa phosphate ore constitutes of Apatite (43.6wt%) as the major mineral, Feldspar (29.0wt%), Iron oxides (14.4wt%), minor quantities of Quartz (8wt%) and the rest being trace minerals. The chemical composition of the ore averages 22.7 % P2O5 with the other constituents being 22.8% SiO2, 19.0% CaO, 7.0% Fe2O3, 4.0 % Al2O3 and 0.2% MgO. Beneficiation studies were performed to investigate methods of concentrating the phosphate values. Preliminary investigations involved detailed identification of mineralogical and chemical properties of the constituents minerals which would form the basis of selective separation of the phosphate values from the gangue. The results of these studies showed that liberation of apatite occurred below the average grain size of 500 ?m. On the basis of the identified mineralogical and chemical properties of the minerals, heavy media separation using Bromoform and subsequently flotation were applied in the beneficiation tests. The results indicate that heavy media separation techniques could not be used to give a final phosphate concentrate. It has to be a pre-concentration process prior to another concentration process. Encouraging concentrate grades were obtained after flotation with a cationic collector, petroleum sulphonate. The optimum pH being 9.5 and the concentration of petroleum sulphonate 1200 g/ton. Under these conditions, the grade was 40.8% P2O5 with 1.65% SiO2 while the combined grade was 50.2% P2O5. On the basis of this test, a treatment flow sheet for this deposit has been proposed.

Copper mineralisation is hosted by quartzite in the footwall of the OS1 Member at the Chingola ‘B’, Mwambashi ‘B’ (Mwambashi Copper Project), Chibuluma, Fitula and Mimbula mines. The host units are located in fault bounded sub-basins to which the overlying shale has acted as an impermeable barrier and reductant for mineralised fluids. It has been postulated that hydrocarbons trapped in the arenaceous footwall sediments may also have acted as reductants that have controlled precipitation of sulphide minerals from mineralised fluids. Whilst having smaller resources than the ore shale deposits, typically several tens of millions tonnes, the grades are generally higher at 2.5% to 4% Cu, with varying Co grades.

August 29, 2007
At the Mwapula prospect from the polymetallic Mulofwe Dome project area, rock chip sampling and mapping has outlined an area of highly anomalous copper-lead mineralisation, including 11.93% copper, 31.50% lead and 212.4 g/t silver, and 1.55% copper, 8.33% lead and 115.8 g/t silver. The mineralisation occurs in quartz veins up to 1.5m in width, associated with malachite, galena, chalcocite and pyrite. The mineralised zone occurs within a 600m wide quartz-veined sheared corridor comprising predominantly quartzo-feldspathic schists and gneisses. The corridor trends north-west, and has been has been defined by mapping over a strike length of 2.4km to date. 97 rock chip samples have been collected from the area, with results received for 28 samples only to date.

• Macrolink, a Chinese mining firm intends to invest USD 42m in developing a copper mine in Mwekera area, 24km north of the Ndola central business centre. Macrolink Resources Zambia Limited, which is also running a mine in the Democratic Republic of Congo, is a subsidiary of Macrolink Group in China with headquarters in Beijing.
• Macrolink Deputy Chief Executive, Philip Che said that in 2009, Macrolink, who had a 25-year mining licence, invested USD 1m to verify historical geological data for Mwekera copper deposit and is now injecting USD 1.5m in exploration to get geological information, complete the project feasibility study and prepare for project development.
• Mr Che said the flotation plant would have the processing capacity of 2,000t per day and that the ores from the underground mine would first be sent for crushing before being concentrated using the froth flotation process to get copper concentrates of 30% copper. Once fully operational, Macrolink Mine would create 625 jobs broken down as 544 for Zambians and 81 expatriates out of which four would be Zambian managers and six would be expatriate managers.

HISTORY
Metalimex, an east European company, explored the Mweze prospect in the early 1970’s and considered the potential for the discovery of economic Cu mineralisation to be high. The culmination of their work resulted in a 12-hole diamond drilling programme, 7 of which were drilled in the Mweze area. Several of these intersected significant copper mineralisation with grades of up to 6% copper.None of the holes were tested for their gold content although gold was recorded from limited metallurgical sample test work...

The Mwomboshi Prospect was first explored by Loangwa Concessions Limited between 1930 and 1932. Rock chip sampling of quartz float returned grades of up to 42.7g/t Au. The Zambian Ministry of Mines conducted an examination of the area during the 1970’s. Exploration included geological mapping, soil sampling and trenching. Thirteen shallow inclined diamond drillholes were completed for a total of 1001.8m. Drilling intersected quartz veins within sulphide alteration zones up to 20m in width. Analytical results of this drilling have not been recovered by Zambezi.

200Mt at 57% Fe, < 0.1% P and S
October 15, 2007
Preliminary modelling work showed that there is the potential to obtain an iron mineralized tonnage of 8 million tonnes per 400m strike length or 20 million tonnes per kilometre of strike at a 60% Fe cutoff and 21 million tonnes per 400m strike length or 52 million tonnes per kilometre of strike at a 55% Fe cutoff. Based on an overall strike length of 6km, this could equate to a potential total project tonnage of between 100 million and 300 million tonnes
In the southwest corner of the Luiri Hill Project is the Nambala iron deposit within the Nambala sub-formation of the Katangan Supergroup. The Nambala sub-formation is a well defined iron stratigraphic unit that extends for about 80km. It generally gives rise to prominent topography in an area of mostly flat terrain. The iron-rich mineralisation at Nambala occurs within metasediments which have been folded into an open, west plunging syncline. The geometry of the syncline is marked at surface by ridges and peaks of the Nambala iron unit.
Nambala was investigated by Garlick in 1948 and Philips in 1958. Three types of iron mineralisation were identified: (1) breccia “ore”, (2) shale replacement, and (3) argillaceous ironstone. The grade of the breccia ore was reported to be 62% Fe while the shale replacement was stated to be 57% Fe. The silica content was given as 9% and 18% respectively and phosphorus and sulphur were both stated to be less than 0.1%. Garlick reported the Nambala iron deposit to be 4 miles (6.4km) long with widths of over 200 feet (61 metres).
In the early 1970s the United Nations Development Program (“UNDP”) undertook a detailed study of an area that included Nambala. It was suggested in the study that Nambala has similarities within Algoma-type banded iron formation. There are two unclassified estimates for Nambala mentioned in the literature. Watts, Giffis and McOuat (1991) stated the “mineral potential” to be 200 million tones at 57% Fe. A separate estimate is stated to be 139 million tonnes at 57.7% Fe. These are considered to be historical estimates and should not be relied upon. In the early 1970s, the Zambian Government through Mindeco investigated building a small steel plant in Zambia using iron ore from local sources. The results were summarised in a Feasibility Assessment dated June 1974 by Mindeco. The report noted that Nambala had the best grade mineralisation of all Zambian iron deposits so far identified.

GEOLOGY
Iron oxide-Cu-Au systems also occur within the African Copperbelt. Current exploration suggests they are most common in the area around the Hook granite. These prospects are characterized by vertically oriented, structurally-controlled hematite-rich breccia zones up to several kilometers in length with late pyrite and chalcopyrite. Intrusive and volcanic rocks within these systems have undergone pre- mineralization
potassic alteration characterized by the formation of potassium feldspar. Potassically altered rocks are then cut by magnetite, which is in turn replaced by hematite during a hydrolytic (sericite-chlorite) alteration event. Sulfidation is the final event resulting in the precipitation of pyrite and then chalcopyrite. A number of minor magnetite deposits are present in central and northern Zambia associated with sodic and sodic-calcic
alteration. These massive magnetite bodies are associated with mafic intrusive (“diorites”) stocks or sills that have undergone extreme sodic alteration, resulting in the formation of albite-actinolite-scapolite assemblages

313: Nchanga - North Pit Wall Colapse
Insurance recovery: on 8 April 2001 the north pit wall at the Nchanga open pit collapsed. KCM subsequently made a claim against its insurers in relation to this incident. At the Relevant Date the liability of the insurers to pay and the amount of any such payment were in dispute.
We have reviewed documentation associated with this claim. In particular, we have been provided with a Memorandum of Meeting authored by Pinsent Masons and dated 4 August 2005. This memorandum notes that "nothing had detracted from PM.s overview that KCM have a good claim and could be awarded a sum in the region, subject to a revision of the quantum, of between US$40 . 50m".
We consider that even an aggressive buyer would have discounted the expected insurance recovery to take account of the time, expense and inherent uncertainty associated with any litigation. There is no objective methodology we can adopt to determine the appropriate level of discount that would have been applied by a purchaser, so we have relied on our judgement and experience to conclude that an aggressive buyer might have factored 50% of the value of the claim into its valuation of KCM. Accordingly, we have included in the cashflow projections an amount of US$22.5m, being 50% of the midpoint of the likely recovery range identified in the Pinsent Masons memorandum

4.3.1.1 Nchanga Underground Mine
The mine was and is accessed by two vertical shafts approximately 945 m deep, both equipped to hoist ore,waste, personnel and materials.
The mining method used was block caving; however, since the orebodies were shallow dipping the block caving method applied was a variation on the traditional method. The mining area was undercut by long-hole drilling and blasting and the ore was allowed to cave into a series of finger raises from which it was pulled by scraperwinches into the ore handling system. The rate of caving was carefully controlled to ensure efficient extraction of the ore and limited dilution, a mining method characterised by a high development ratio.
Nchanga Underground was and remains a wet mine pumping 75,000 to 85,000 m3 of water day. Most of this water was pumped from the 2800 level and some from the 1600 level. Water control in the mine was good and did not hamper the mining operations.

319: Ndola East (AfricanEagle)
RESOURCE BASE
40Mt at 0.76% Cu
The Ndola East copper deposit occurs in north-northwest striking Lower Roan sediments on the eastern flank of the Ndola Dome. From the results of exploration during the 1950s and 1970s, the deposit was estimated to contain mineralisation amounting to some 40 Mt at 0.76% copper over a strike length of 3.5km. Structural complications including thrusting and overturning of strata were noted in the north. The reported drill hole intersections suggest that the copper grade increases with depth to a maximum of 1 to 1.5%.
Given that the 1960s drill holes were on a very coarse grid pattern, spaced approximately 1000m by 500m, we believe the deposit has not yet been sufficiently investigated. There is potential for shallow oxide mineralisation and deeper sulphide ores over a strike length of around 7.5km around the Ndola Dome.

AREA
May 13, 2008
At the Ndola South target, geochemical soil sampling completed in late 2007 revealed an extensive low tenor copper anomaly associated with folded Lower Roan strata. 12km to the west, these rocks contain the Bwana Mkubwa mine, one of Zambia's oldest and richest copper mines, now owned by First Quantum Minerals.
The Company recently completed a programme of shallow (30-40m) Reverse Circulation drill holes to test the soil geochemical anomaly. Analysis of drill chippings, using the Company's field XRF analyser, indicates that there is up to 0.2% copper present in the leached saprolite derived from the target horizon. The drill samples have been submitted for assay to a certified laboratory.
The Company is currently conducting an Induced Polarisation (IP) survey of Ndola South and the results received so far show high chargeability at a depth of 50m or more beneath the soil geochemical anomaly. This suggests that stratiform copper sulphide mineralisation may exist at depth.
The Company considers Ndola South to be a significant exploration target and plans a series of deep drill holes once all the results of the IP survey have all been received and interpreted.

NKANA UNDERGROUND OPERATIONS
April 2010
Currently, MCM mines between 3.5 and 4.0 million tpa (tonnes per annum) of ore from its four underground mines. Due to depleting ore reserves in the Central Shaft and Mindola North Shaft, it is projected that the total amount of ore to be mined from the SOB and Mindola Main shafts will be 1.8 million tpa by 2015.
Figures 4-1 and 4-2 show the 10 years projection of Nkana Copper ore and contained copper production respectively. Nkana mine currently produces about 3.5 million tpa of ore (approximately 65 thousand tons of contained copper). It is projected that ore production will drop to approximately below 1.5 million tpa of ore (30 thousand tonnes of contained copper) by 2015 without the implementation of the Synclinorium project. It is also projected that contained copper production will increase to 5.0 million tpa of ore (or 100 thousand tonnes of contained copper) by 2018 with the implementation of the Synclinorium project.

Rock Hoist Shaft
MCM proposes to sink and line a 7m diameter down cast rock hoisting shaft, 1260m deep for the hoisting of 4 million tpa of ore. The rock-hoisting shaft will be constructed by conventional shaft sinking method. The type of actual sinking equipment will be evaluated for
the most efficient sinking cycles e.g. mucking method, drilling method, and lining or means of support.
Ventilation Shaft
The increase in the mining activities in the Synclinorium will require improving the ventilation in the area. Hence, one Ventilation Shaft is proposed to be raise bored to expel used air from underground in order to ensure the health, safety and wellbeing of the workers. The ventilation shaft will be located at 75 metres away of the rock-hoist shaft described above.The shaft will be 6 metres diameter and 1,180 metres deep.

Zambia's Konkola shuts Nkana smelter
NKANA OPERATIONS
KCM Nkana is situated in Kitwe, Zambia.
The Nkana Smelter is the largest primary copper production plant in Zambia. The plant treats concentrates mainly from Nkana, Nchanga and Konkola mines which are wholly owned by KCM to produce up to 150000t of new copper.
Nkana Smelter
The smelter produces high grade anodes, which are electrolytically refined. Sulphur dioxide gas produced by the Converters is converted into sulphuric acid which is then used at the Tailings Leach Plant, Nchanga for recovering oxide copper. The smelter also produces discard slag from the reverbs that is rich in cobalt which is stored for future reclamation.
Nkana Refinery
The Nkana Copper Refinery produces electrolytically refined copper in the form of cathodes. The copper meets the LME premium quality grade. The tankhouse has a capacity of about 180000t of finished copper per annum.
Nkana Acid Plants
There are two single contact sulphuric acid plants at Smelterco, namely No. 3 and No.4 plants. No.3, the largest is still operational. The plant has a design capacity of 1050 t per day acid.

KCM VALUATION - ROTSCHILD
4.4 Third Party Smelting and Refining
Toll treatment of concentrate by smelters is common throughout the world, but had nottraditionally been undertaken in the Zambian Copper Belt as mines tended to be developed with their own associated processing capacity. At the Relevant Date this was changing, and it appeared likely that toll treatment would become more commonplace.
IMCL states that the existing smelter at Nkana was uncompetitive in this market due to its low recoveries (modern smelters typically achieve 97% recoveries but the Nkana smelter only averaged 92% recovery). However, IMCL s assumption is that the smelter would be the subject of a significant upgrade pushing the recovery up to around 95%. Although immediately post the upgrade Nkana would have limited spare capacity, post closure of Nchanga in 2016 it would have the ability to take approximately 30,000 tonnes per annum and it would be commercially reasonable for KCM to seek to toll process third party concentrate.
However, at the Relevant Date it would have been difficult for a prospective buyer to establish with any degree of certainty the viability of toll processing and the benefits that might accrue more than ten years hence:
- Mopani had already committed to the expansion and upgrading of Mufulira and CNNC was also considering a new smelter. There was therefore the prospect of significant competition for concentrates in the Copper Belt and, even post the upgrade, Nkana s cost structure would be high and it would be unlikely to attract material until the other smelters were at capacity; and
- the level of supply was unclear given the uncertain remaining lives of many mines, the absence of final decisions to bring new mines on stream and the uncertainty at the time regarding whether projects in the DRC would proceed and, if so, whether they would produce concentrates or would instead adopt a hydrometallurgical approach.
The availability of material for Nkana was therefore uncertain.
In view of the above, although a buyer might conceivably have identified this as a future source of upside, in our judgment it is unlikely to have resulted in it being willing to offer materially more for KCM.
4.5 New Smelter
Although KCM was clearly considering an upgrade to Nkana, there is no evidence that, prior to the Relevant Date, the Company was considering a completely new smelter (albeit this alternative approach was decided upon shortly thereafter). We nevertheless believe that a buyer of KCM at the Relevant Date might have factored this alternative into its evaluation given:
- the economics of the upgrade are adversely affected by the limited scope for cutting costs because the smelter would still rely on many labour intensive processes and outdated pieces of equipment needing significant ongoing maintenance; and
- the continued costs of transporting the concentrates to Kitwe.
In its report IMCL has estimated the capital costs of a brand new smelter and determined a net present value benefit versus the upgrade of approximately US$50m at a 10% real discount rate.In the context of a (hypothetical) sale of KCM at the Relevant Date, we are sure any buyer
would have spent considerable time and effort thinking through the smelter options, given that the status quo was operationally unsatisfactory and KCM s own thinking had still not fully evolved. With the passage of time and subsequent developments it is difficult for us to judge what conclusion buyers might have reached and hence to what extent they might have identified and reflected all or part of the benefit of a new smelter (or indeed potentially a more attractive upgrading option) into the offer. We conclude, however, that the approach in the IMCL Reference Case is probably conservative and that a buyer may have factored into its analysis smelting options that increased the value.

341: TD13 - Uranium Dump - Nkana
Nkana Tailings Dam 13
July 29, 2009
Abandoned Kitwe uranium mill tailings to be relocated for safe disposal (at TD15)
The Copperbelt Environment Project (CEP) is to spend over $1.3 million to dispose 40,000 metric tonnes of uranium tailings dumped at TD 11 and TD 13 in Kitwe's Mindolo Mine Township.
CEP Communications Speciality Mumbuna Kufekisa told ZANIS in an interview in Kitwe today that CEP, in conjuction with ZCCM-Investment Holdings , has decided to dispose of the uranium tailings dumped at TD 11 and TD 13 from mining activities in the 1960s as they were a health and environmental hazard. Mr Kufekisa said the uranium would be taken for storage where they would be buried in a disposal cell and covered with laterite and vegetation at a Mopani Copper Mine dump site. He disclosed that the exercise, which was being undertaken by Copperfield Mining, would be done over a period of four months and at a cost of $1.3 million (Lusaka Times July 29, 2009)
ZCCM-IH Plc has engaged German consultancy WISUTEC Wismut Umwelttechnik GmbH to undertake an environmental and social impact study at two uranium dumps in the Kitwe area. The dumps are in an area where ZCCM-IH already has a programme in place of resettling residents to a safer area. So far, 600 people who were living near the uranium dumps have been resettled elsewhere.
ZCCM-IH environmental officer Cyril Lukeke told media practitioners who visited the company's projects under the World Bank-supported Copperbelt Environment Project (CEP) that study would cost about 500,000 euros. Lukeke said the consultant has already collected samples from the two dump sites to ascertain the effects of the uranium residue on the community living nearby. The study started in April and is billed for completion next year, after which ZCCM-IH will determine the remedial measures to be taken.
Uranium was mined at Kitwe, where the mine is now operated by Mopani Copper Mines (MCM) Plc, during the 1950s when a company called Amco was contracted to sink shafts at Mindola. The uranium was shipped to the United Kingdom, whose colony northern Rhodesia was then, but since then, the mineral has not been actively mined. (Mineweb June 11, 2007)
"The only uranium production [in Zambia] was done in the early 1950's at the Nkana copper mine, Kitwe, in the copperbelt. From about 100,000 tonnes of uranium ore mined at a grade of 0.19 per cent U, about 100 tonnes U were produced." (NEA/IAEA: Uranium Resources, Production and Demand, 1989)

Slag is excavated from the Nkana slag dump by front-end loader and occasionally by drilling and blasting. The material is concentrated through crushing and passing over a magnetic drum. The concentrated slag is then transported 35 kilometres by road to Chambishi Metals, where it is mixed with various reagents such as anthracite, coal and malachite. It is then fed into the COSAC (Cobalt from Slag and Copper as a by-product) furnace, 40 MW DC single solid graphite electrode electric furnace. The resultant cobalt-copper alloy is tapped and routed through the atomiser and pressure leach, where it is made suitable for electrowinning

Chipirinyuma Resource base:
2Mt at 4% Zn
Prospects: Chipirinyuma, Mpongo and Umba River
A number of companies and government agencies, including Zamanglo, the Geological Survey of Zambia, Mindeco, a Zambian parastatal exploration company, and most recently, RTZ, have carried out exploration in the Nyimba area and several prospects have been identified.
The Chipirinyuma Prospect was discovered by a combination of stream sediment geochemical survey and aeromagnetics undertaken by Mindeco between 1975 and 1979. Trenching revealed massive,possibly stratabound, sulphide bands between 3 and 12m thick occurring within gneisses. The major sulphide is pyrrhotite, with lesser amounts of pyrite, chalcopyrite and sphalerite. The bands outcrop as gossans forming prominent ridges in the area that can be traced along strike for approximately 6 km. Results from four of six diamond drill holes completed to test the gossans at depth include up to 4m at 5.3% Zn and 0.9 % Cu. During the mid 1990s, RTZ drilled 5 RC holes targeting a geophysical anomaly at the extreme western end of the prospect, away from areas of known gossan outcrop. One hole intersected grades of up to 4% Zn and all of the other holes intersected mineralisation of some form.
The gossans of the Mpongo Prospect were initially discovered in the 1930s, but first explored in detail in 1963, when Chartered Exploration re-sampled old trenches and completed 11 diamond drill holes over a 1,500m strike length to investigate a carbonate-rich haematite-magnetite ironstone sequence. One of the holes returned an intersection of 2.5% Cu, 4.3% Zn and 0.8% lead (Pb) over 3.4m from a depth of 61m. The area was further explored in 1995 by RTZ, who undertook a ground magnetic survey and a five hole diamond drilling programme, of which only one hole was completed. Three mineralised horizons were defined by mapping and an exhalative horizon traced for 40 km along strike. The completed hole intersected 24.5m at 0.53% Cu, 3.73% Zn, 1.2% Pb and 52.8 g/t silver (Ag).
The Umba River Prospect was investigated for gold mineralisation prior to 1930. More recently, in 1973, an aeromagnetic survey defined a series of anomalies, and geological and regional geochemical surveys revealed the presence of Cu-Pb-Zn mineralisation. The Chinkombe shear,related to the MDZ, was traced for over 6 km along strike and high gold values were obtained from grab sampling. The high gold grades, however, cannot be verified as there were problems with the laboratory used for this work, and six RC holes drilled by RTZ produced no significant results.

Pamba Hills Iron ore Prospect
Zambia imports all its steel and there is no local production of iron. However, the country has substantial resources of iron ores (in excess of 500Mt) and these can be broadly classified into a sedimentary type and a pyro-metasomatic type based on chemical composition and geology.
The sedimentary ores are high in silica (around 25%), but low in phosphorus (0.01-0.03%) as exemplified by Pamba and Kasumbalesa. The pyro-metasomatic ores are high grade ores in respect of iron, but are also high in phosphorus, generally 0.2 to 0.5%. Typical examples are those found in the Mumbwa District. Over 50 individual deposits have been recorded and a few found closer to the line of rail have been studied in some detail. The Nambala deposit near Lusaka is over 200Mt with 57% iron, the Sanje deposit is 10Mt with a grade of over 62%, the Kasempa group with ten deposits has 229Mt with 66% Fe, while the Lubungu deposit is 175Mt with 56% Fe.

The Sasare Mine, situated on the southern side of Lungamondi Hill, was worked sporadically between 1906 and 1942. Although records are sparse, production during this period is recorded as being some 12,280 oz Au (390 kg). Two orebodies, Sasare East and Sasare West, were mined via adits and shafts to a depth of about 100m. The Sasare East orebody strikes east-west, has a strike length of about 400m and comprises a single persistent quartz vein which splits into several veinlets up to 13m apart. Underground sample grades are reported to have averaged between 8.0 and 9.6 g/t Au. The Sasare West orebody lies about 1.6 km to the northwest of Sasare East and consists of a single vein up to 3.0m wide, with an average recorded grade of 8.0 g/t Au.

8. MINERALIZATION
Mineralisation in the southern limb of the Sebembere syncline is restricted to feldspathic quartzite aswell as shale and dolomite horizons. In the northern limb, the feldspathic quartzite is absent and limited mineralisation is present within an andesitic lava (on the same stratigraphic positions as the quartzite within the southern limb). The mineralised zone within the central zone (cf. Section 6.2.3.1) extends from < 30 m to > 100 m. According to Watts et al. (1991) the mineralization package isdivided into three vertical zones.
8.1 Zone 1 - Leached zone (0 m 30 m)
Zone 1 is located within the feldspar – quartzite horizon and supposed to be 1,100 m long at it upper levels with thickness of mineralization ranging from 0.85 m to 7.88 m and the Cu content varies from 0.91 % to 3.39 % (Catana, 1974).
8.2 Zone 2 - Partially leached and oxidised zone (0 m to 100 m)
Zone 1 is also located within the feldspar – quartzite horizon and supposed to be 1,300 m long at it upper levels with thickness of mineralization ranging from 1.23 m to 13.23 m and the Cu content varies from 0.91 % to 2.33 %.
8.3 Zone 3 - Supergene enrichment zone (>100 m)
Limited information is available for zone three, but Catana (1974) states the mineralization in zone 3 to be 2.6 m in thickness and Cu content 1.56 %.

RESOURCE BASE - 2009
Inferred 1380Mt at 0.78% Cu
Snowden’s estimated resource is based on a total of 62 bore holes - 31 drilled by Kiwara and 31 by previous site owners. The resource is close to surface and open on strike to the south west, thus implying an open pittable mine with strong potential for further resource finds.
STATUS - RESOURCE DRILLING
• Resource drilling commenced in March 2010; nearly 50,000 metres completed in 148 holes to date with 14 rigs now on site
• Detailed sections drilled through central part of the resource demonstrate excellent continuity of mineralization
• Wide intercepts of mineralization (>200 metres) encountered down dip of previous drilling
• Drilling emphasis now moving to strike continuity and extensions
• A timeline has been established to complete a mining licence application by Q2 2011
• Preliminary metallurgical testwork has demonstrated that the ore can be concentrated using standard flotation technology typical to most mines in the Copperbelt
• Social and economic studies are in progress with a view to delivering a full Environmental Impact Statement in Q2 2011
• Regional exploration program on potential satellite copper and nickel prospects has been initiated
• A decision to proceed with development of the project is subject to results of these resource and mine studies,securing all relevant permits and approval by the Company’s board of directors
• Significant drill program underway with 71 drill holes for 21,000 metres completed to date
• Visual results suggest excellent continuity of mineralization
• Drilling emphasis now moving to strike continuity and extensions
• Aim to complete 65,000 metres of resource drilling by year-end and generate a new resource model in early 2011
At the time of acquisition Kiwara had begun an in-fill drill program at Kalumbila to determine a mineral resource estimate for the properties. In Q2, six drill rigs were actively focused on two detailed sections over the central resource. These have confirmed excellent continuity of mineralization that will allow for further resource drilling to cover a larger area. Emphasis has now moved on to widely spaced drilling to test the ultimate extent of the Kalumbila ore system. An economic assessment including metallurgical test work, engineering and geotechnical studies are planned in the second half of 2010.
The project [Kalumbila] could be producing as early as 2013 and could churn out as much as 150,000 tonnes of copper a year (Mineweb)

379: Valeria South U3O8 (Equinox)
The Valeria South uranium zone has a north-south strike of 1000 m, and an east-west extent of 220 m. In addition, uranium can also be found in relatively low grade, discontinuous pods in the footwall gneisses, where it is free of copper; this style of occurrence has not been targeted as the potential to generate significant tonnes and continuous ore shoots appears limited. Valeria South is open to the south.

Interesting Goings-On At Zambian Consolidated Copper Mines
There have been some significant developments down in Zambia in the wake of Minesite’s earlier story that the Zambian government might be prepared to reconsider the new levels of mining tax that it’s imposing, if the government’s own 87 per cent owned Zambian Consolidated Copper Mines (ZCCM) started to receive meaningful dividends from its Copperbelt joint ventures. A particular emphasis was laid on the Kansanshi project.
We now understand that First Quantum, the Canadian miner which operates Kansanshi, has entered into discussions with ZCCM about the payment of dividends from ZCCM’s accumulated but undistributed share of Kansanshi’s profits. These, after taking account of ZCCM’s share of Kansanshi development and capital spending, are believed to be well north of US$100 million and rising fast. The problem that has arisen for ZCCM is that when the Zambian copper industry was restructured in the early part of the decade, the joint venture agreements between the new foreign operators, ZCCM, and the government did not address the payment of dividends to the minority shareholder, ZCCM. Some operations, such as Mopani and Konkola, have occasionally paid dividends, but as the copper price has stayed high the profits flowing to the foreign operators have risen sharply, far outpacing any dividends flowing to ZCCM.
In November of last year ZCCM’s then chief executive, Joseph Chikolwa, addressing a conference in London, revealed that he believed that ZCCM’s net asset value was around US$1 billion or US$11 per share. This figure derives from a valuation done for the company by, we believe, Rothschild. ZCCM is mainly traded in Paris where it is priced in Euros. The US$11 figure was then equivalent to around €8.00 per share (the current price is around Euros €2.50; in October 2007 the share price reached Euros €6.40). Those who know both ZCCM and First Quantum generally consider that Kansanshi is the most valuable and profitable of the current Copperbelt mines.
However, in the last week or so, an intriguing transaction has been proposed in India concerning Vedanta’s Konkola copper operation. The Anglo-Indian group now owns a 79 per cent stake in Konkola following the controversial acquisition of ZCI’s 28.4 per cent holding. Following the recently announced re-structuring of the Vedanta group, Sterlite Industries India (SII), 60 per cent owned by Vedanta, is to acquire Vedanta’s 79 per cent stake in Konkola, in exchange for 364 million Sterlite shares. Currently Sterlite shares trade in Bombay at Rs505 (US$11.20), but as part of the Vedanta restructuring SII is getting rid of its stake in Madras Aluminium (MALCO) so, with the issue of new shares to Vedanta as well, SII’s residual value will have to be adjusted.
The Indian broking firm, Emkay Shares, has calculated a residual per share value for SII, once all the restructuring has been completed, of Rs355. MacQuarie suggests a slightly lower figure. This translates into a value for the Konkola asset of Rs355 times 364 million new SII shares, or Rs129 billion. Since that value is for 79 per cent of Konkola, it follows that if a similar value is attributed to ZCCM’s residual 21 per cent stake, the residual stake would be worth Rs34 billion, or €530 million, or €5.88 per ZCCM share.
It’s worth pointing out in passing how these figures compare with Vedanta’s US$213 million take-out price for ZCI’s 28.4 per cent stake in Konkola. In today’s circumstances ZCI’s holding would have been worth around US$990 million! It’s little wonder that ZCI fought so long and hard, if unsuccessfully, to get its’ stake valued on a current market basis, rather than on the 2003 copper price basis that was used.
Getting back to ZCCM, if it was interested in selling its Konkola stake the price would have to reflect current copper prices, as SII stake clearly does. But of course Konkola is not considered the jewel in ZCCM’s crown. That honour undoubtedly falls to Kansanshi. Last quarter ZCCM’s share of Kansanshi’s after tax profits was US$31million, or US$124 million annualised. If one applies the earnings multiple which operator and majority Kansanshi shareholder, First Quantum, currently sells on in the Canadian market - around five times - then ZCCM’s Kansanshi stake is worth US$620m, or €440 million, or €4.90 per share.
So we already have ZCCM, using reasonable market assessed values, with a net asset value of €10.78, against a current share price on the Paris Marche Libre of €2.50, and we have not yet ascribed a value to ZCCM’s holdings in Konkola North, Mufulira/Nkana or any of the other Copperbelt interests, such as Chambishi, Chibuluma and Luanshya, not mention its stakes in Ndola Lime, Maamba Collieries, Copperbelt Energy, Equinox Minerals and Albidon.
So what is ZCCM itself up to in order to try and encourage a higher market value for its shares, and what problems does it face in achieving this? The first thing to say is that ZCCM’s management was only vaguely aware that its shares traded in Paris and did not have up-to-date information on price movements there. This is because the Government has 87 per cent of the company and private shareholders are largely unknown as their holdings are mainly in nominee names. ZCCM shares are also listed in London and ZCCM pays fees to Cazenove to maintain that listing, but don’t hold your breath whilst the switchboard locates the responsible Caz executive! ZCCM is considering what to do about its London listing and whether its Paris trading facility can be expanded, but since it has not filed accounts for 2006, 2007 or 2008 (year to June)it may have difficulty in achieving anything in the near future.
The accounts for both 2006 and 2007 have been prepared but we understand that there is a problem between ZCCM’s board and the company’s auditors regarding certain balance sheet asset valuations. The 2006 accounts are promised in a few weeks, not a new promise unfortunately. Following the publishing of the 2007 accounts it would be possible for ZCCM shares to be elevated to the next rung of Paris trading where there would be continuous session trading rather than the unreliable and quixotic daily call over on the Marche Libre. Whilst the market in ZCCM shares would remain thin in the circumstances of continuous trading, it would, nonetheless, be reasonable to expect daily volume to rise from a few thousand shares at best via the present calling-over facility, to around 50,000, which would be equivalent to around 100 per cent turnover of the minority stake annually.
Another issue that remains unresolved is the level of ZCCM’s debt, which stands at around US$500 million. This all relates to its past role as the operator and owner of Zambia’s copper mines. Whilst this figure appears on the face of it to be an enormous burden to ZCCM in its present reduced circumstances, it needs to be borne in mind that the debt is almost entirely attributable to the Zambian government, and it carries neither repayment date nor interest rate. There are some at ZCCM who believe that since the Zambian government has had most of its foreign debt forgiven by the international community, the Government in turn should cancel ZCCM’s debt. This the government refuses to do, but it has intimated to the company that it would consider converting the debt into preferred capital, which would carry a right to convert into new ZCCM equity. Some of this new equity could then be sold to local and foreign investors to raise cash for the government. ZCCM’s proposals on this have been with the government for over a year now and an early resolution of the issue seems unlikely!
The company has been talking to a group of French investors, the first time it has ever acknowledged the existence of its 13 per cent largely private investor minority. Whilst these discussions have been wide ranging they have laid particular emphasis on matters of investor relations and communications, where ZCCM is very weak. The company has engaged a South African IR firm to do an audit of ZCCM’s current IR practices, such as they are, and make recommendations. This is not the first time that an IR audit has been performed and it is unlikely that the South Africans will come up with anything that is not pretty clear already to the French ginger group.
Whilst is also pretty clear is that ZCCM is being right royally shafted by its foreign partners on the issue of dividends from the Copperbelt mines, the company unfortunately lacks aggressive and motivated management, which doesn’t help. For many years now its staff have acted as administrators dealing with issues, such as pensions, relating to its historic position as operator of the Copperbelt mines. ZCCM is anxious to develop its role as an investment holding company and to manage its current assets. Therefore the imperative now is for ZCCM to strengthen its management in order to fulfil these ambitions.
At the same time the Zambian government is prone to drag its feet and has recently said that it has no intention of selling a share of its 87 per cent holding, even though locals have suggested that this would reinvigorate its practically dormant local quote on the Lusaka Stock Exchange. This refusal, which goes against previous government policy to realise value from the ZCCM stake at the right time, also creates problems with regard to the debt issue and the proposed preferred share swap and subsequent sale...

Funding history:
Northern Rhodesian copper played a crucial role in the economy of the Federation. Even after a dramatic fall in the price of copper during 1956, the industry continued to contribute over fifty percent of the value of the Federation’s exports.12 This dominance led the Federal government to approach Anglo and RST for assistance on when it was struggling to provide the necessary finance for the construction of the Kariba Dam during December 1955. Both copper companies were counting on an increased and more reliable power supply, and so it was in their interests for the dam to be completed on schedule. At the meeting, the Federal government was represented by its prime minister, Lord Malvern, and his deputy Roy Welensky. Ronald Prain, RST’s chairman and Harry Oppenheimer, the managing director of Anglo American, represented the copper industry. Malvern revealed that the shortfall in financing the scheme would be £20 million over the following five year period, and that the railways would require a further £10 million.13 He suggested Anglo and RST should cover this shortfall in the form of loans. Should the companies not agree to this, Malvern proposed instigating an export tax on copper to the value of fifty percent of all profits.
Both RST and Anglo American were in agreement that this would ‘have disastrous effects on the credit of the country’, furthermore it would ‘kill new investment’ and offer no incentive for the companies to keep production costs low.14 As a result of these ‘unnecessary strong-armed tactics’, as Prain later recalled, the companies agreed to provide £10 million each towards financing the Kariba project, and agreed to accept a surcharge on the power produced by Kariba until a further £10 million had been paid.15 To this was added a loan of £4 million from the BSA Company which brought the total amount invested in Kariba to £34 million.16 The tactics adopted by the Federal government illustrates the confidence with which it viewed its position in 1955. As will be demonstrated below, the pressure on the Federal economy brought about by the loss of copper revenue altered the balance of power. While in 1955 it was possible for the government to threaten the copper companies in order to secure their co-operation, this situation would soon change.
