Trek Metals Limited advised that a review of exploration data from the Valley of the Gossans (VOG) prospect and the greater Pincunah Project in the Pilbara region of WA has resulted in a new mineralisation model for the area. The identification of epithermal mineralisation potential at VOG as part of a likely precious metals system has upgraded the previously identified Conductor `A', which has yet to be tested by drilling. A robust multi-element As, Se, Sb, Bi, Ag, Cd, Pb, In, Cu, Mo, Au, S & Te metal association has been defined in soils at Valley of Gossans Prospect. This metal association also defines subsidiary targets including those located immediately north-east of Valley of the Gossans extending to Conductor `A'. All mafic and sedimentary units are strongly altered. Alteration is more difficult to define in ultramafic samples where the least altered composition is quite close to chlorite. Sericite alteration is most closely associated with mineralisation. A zonation from possible chloritic (propylitic) inwards to sericite (phyllic) alteration was recognised and the widespread presence of chlorite was confirmed
via ASD hyperspectral analysis of two drill-holes (VRC006 & 023). If Valley of Gossans is indeed a high-sulphidation epithermal system, the mineralogy and zonation with a predominance of propylitic alteration (chlorite-sericite-carbonate) with possible minor dickite suggests that current exposure is deep in the system, below potential economic gold mineralisation. Potential for deeper porphyry copper mineralisation may still exist. Although the currently observed absolute gold grades are low (<0.4g/t Au), it is important that gold is correlated with the best mineralisation in the system so far. If there is porphyry copper mineralisation at depth, it is reasonable to expect that it is gold-bearing. The low temperature metal suite that overlies epithermal deposits is Hg-Tl-(As-Sb). While there is very high As and Sb anomalism at VOG, the Hg and Tl are not so pronounced over the main As-
Sb anomaly. Furthermore, "high temperature metals" like Bi and Cu don't fit with low temperature upper levels of an epithermal story. However, at Conductor `A' there is a very pronounced Hg and Tl anomalism in association with a
comparable multi-element geochemical signature to that at the main VOG anomaly. It would be reasonable to interpret that Conductor `A' could represent a higher-level portion of the epithermal system, which should be more prospective for economic accumulations of precious metals.
