The process of ore reserve estimation is discussed. The added complication that each of the joint partners had a different perception of the deposit is considered., The process of ore reserve estimation is discussed.

Primary mineralisation intersected is finely disseminated or associated with quartz veins and consists of pyrite, pyrrhotite, chalcopyrite, minor molybdenite, arsenopyrite and scheelite and rare free gold, tetrahedrite and stibnite. The only significant mineralisation occurs in the intermediate to felsic volcanic and the diorite intrusives., Primary mineralisation intersected is finely disseminated or associated with quartz veins and consists of pyrite, pyrrhotite, chalcopyrite, minor molybdenite, arsenopyrite and scheelite and rare free gold, tetrahedrite and stibnite.

In the profiles studied, components can be divided into those which are generally leached (Ba, Co, La, Mn, Ni, Rb, Sr, Ta, Y, Zn, CaO, K2O, MgO, and Na2O); those which are mobilised and reprecipitated within the profile (Au, Ce, Cr, Cu, Mo, and Fe2O3) and those which are essentially residual (Nb, Sn, Th, V, W, Zr, A12O3 and TiO2). Residual components have been mobilised in the profile but have not been transported any great distance. Anomalous concentrations of As, Au, Cr, Cu, Mo, Nb, Sn, Th, V and W, retained at the surface within recognisable lateral distance (100-150 m) of their bedrock sources, appear suitable as either direct or indirect indicators of bedrock mineralisation. Significant concentration of gold occurs within the lower part of the lateritic hardcap and upper part of the underlying nodular B-zone. Local concentrations of gold lower in the profile are attributed to still-stands of the water table during periods of generally increasing aridity over the last 30 million years., In the profiles studied, components can be divided into those which are generally leached (Ba, Co, La, Mn, Ni, Rb, Sr, Ta, Y, Zn, CaO, K2O, MgO, and Na2O); those which are mobilised and reprecipitated within the profile (Au, Ce, Cr, Cu, Mo, and Fe2O3) and those which are essentially residual (Nb, Sn, Th, V, W, Zr, A12O3 and TiO2).
