Chisawa Cu (ZRL) - Zambian Copperbelt (sitios de interés)

 

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.

Commenting on the announcement, Julian Ford, Managing Director of Zambezi Resources, said:

 

 

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.
