To investigate the possible Cu-Ni-PGE mineral sulphide mineralisation potential of a known buried mafic / ultramafic layered igneous intrusive complex situated within the Cambrian Kanmantoo Trough near Ki Ki in the upper South-East, the licensee and its joint venture partners variously undertook reprocessing and modelling / interpretation of existing aeromagnetic data, rotary mud/diamond core drilling (3 holes for a total penetration of 746.4 m, including 255.1 m cored : holes KK01 and KK02 were partly PACE Initiative - funded during 2005 as Project DPY1-32), geochemical assaying and petrological studies of drill cores, and also acquired and processed / interpreted a gravity survey of 560 stations. The last diamond drillhole, KKD-07-05, was completed in February 2007, reaching a total depth of 348.4 m. It encountered dense mafic/ultramafic volcanic rocks (amphibolites, schists) and banded metasediments carrying elevated nickel and chromium contents, but no significant sulphides were seen. This outcome was very disappointing after the earlier success of PACE drilling carried out on the Ki Ki prospect by Vintage Exploration & Mining Pty Ltd in July 2005, when hole KK02 penetrated an ultramafic rock that contains visible nickel sulphides and magnetite, which yielded assays of up to 0.135% Ni, 0.125% Cr and 34.3% Mg.
