The Blue Mountain prospect is a relatively recent discovery resulting from the follow up of a bedrock lead geochemical anomaly. The prospect has been subject to sporadic exploration by others , including RAB, RC and diamond drilling over the past 20 years with most work completed within the first 3 years of discovery. Blue Mountain has a bedrock lead geochemical anomaly extending over a length of 1,500 metres and width of 460 metres based on the 750ppm lead contour. Anomalous zinc values are coincident with the lead anomaly. Higher lead values within the lead anomaly can be correlated with low grade zones of lead-zinc mineralisation intersected by limited historic RC and diamond core drilling.
Three distinct mineralised zones are interpreted with these being typical of Cobar-style mineralisation. Significant drill intercepts include 29.0 m @ 1.15% zinc and 0.32% lead and 15.2 m @ 0.96% zinc and 0.36% copper. To the east of the lead anomaly, a copper anomaly of similar size is also defined. The copper anomaly has never been drilled.
