Trek Metals Limited Announces Review Highlights Epithermal and Precious Metals Potential At Valley of the Gossans
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.
