HISTORY
• 1930s: Prospectors discovered copper in the Lumwana East River adjacent to the Malundwe copper clearing.
• 1957 to 1961: Roan Selection Trust Limited (“RST”) conducted regional geochemical and geophysical exploration in the Mwinilunga Concession that covers Lumwana.
• 1961 to 1965: RST drilled the Malundwe discovery hole in 1961 and the Chimiwungo discovery hole in December 1962.
• 1966 to 1968: RST fieldwork was limited to the collection of environmental baseline data. A mining scoping study, including the first resource and reserve estimation,was completed by RST in 1968.
• 1969 to 1974: American Metal Climax Inc (“AMAX”) took over RST and a new company called Mwinilunga (1970) Limited was formed to explore Lumwana through a joint venture between AMAX and Anglo American plc. During this period the Chimiwungo South mineralization was discovered.
• 1975 to 1976: The Zambian copper industry was fully nationalised and Lumwana was transferred to Mindeco Limited (precursor to Zambia Consolidated Copper Mines Limited (ZCCM)). Rio Tinto-Zinc Corporation (R.T.Z.) Consultants were commissioned by Mindeco to complete a pre-feasibility study in 1976.
• 1981 to 1990: Azienda Generale Italiana Petroli (“AGIP”) in joint venture with Compagnie Générale des Matières Nucléaires (“COGEMA”) conducted uranium exploration in the Mwombezhi Dome. A drilling program was conducted by the joint venture in the two deposits and the 1990 Pre-feasibility Study was completed by Mining Italiana S.p.A, which focussed on developing the Valeria copper uranium deposit at Malundwe and a small portion of the Chimiwungo deposit.
• 1992 to 1996: Phelps Dodge applied for the Mwombezhi Dome PL in late 1992 and commenced exploration re-focusing on the two copper deposits. Two pre-feasibility studies were also completed applying different development scenarios.
• 1997 to 1999: Phelps Dodge attempted to farm-out the project with a number of limited economic / mining studies completed by both Phelps Dodge and potential joint venture partners.
• 1999 to 2000: Equinox entered into a joint venture with Phelps Dodge in August 1999 and completed a due diligence study which included reporting Mineral Resources in compliance with the JORC Code by consultants, Resource Services Group.
• 2000 to 2001: Equinox commissioned Bateman Engineering Pty Ltd (“Bateman”) to conduct a pre-feasibility study that included reporting Mineral Resources in compliance with the JORC Code and mine design by Mining Resource Technology Pty Ltd (“MRT”).
