1999 Annual report of exploration EL 6640 - Batchelor

Abstract

New resource figures were calculated using all boreholes information such that it can be used in a prefeasibility study of the development of the nearly Browns Deposit. The calculations have included high Cu content ie >0.5% with variable Co values thus 4.2 million tonnes @ 0.922% Pb, 1.10% Cu, 0.214% Co, 0.21 Ni, 0.179% Zn. At a low Cu content ie < 0.5% with variable Co values gives 8.2 million tonnes @ 0.377% Pb, 0.167% Cu, 0.103 Co, 0.101 Ni; 0.178 Zn. The combined total is 12.4 million tonnes @ 0.561 Pb; 0.485% Cu; 0.141 Co, 0.138% Ni and 0.178%
