Abstract

Indications of potential Ni-mineralisation at Ombuku, on the western edge of the Kunene Anorthosite Complex in northern Namibia, were obtained from a regional stream sampling program undertaken by Anglo American plc from 1998 to 2003. Ground IP, AMT and subsequent TDEM geophysical surveys and a VTEM survey flown by ANL, have delineated several drill-targets around the new ultramafic satellite intrusions discovered at Ombuku. Drilling to date has intersected 0.4% Ni and 0.15% Cu over 24.66m (0.3% Ni cut-off) and 0.53% Ni and 0.24% Cu over 4.3m (0.5% Ni cut-off), in disseminated sulphides. This paper discusses the geophysical surveys undertaken and the potential for identification of a large Ni-sulphide resource through further exploration.
