Nov 17, 2009 (A Wilson) - The mineralization consists of sporadic pyrite, quartz, magnetite and a trace of chalcopyrite in small veinlets and lenses. The mineralization is irregular and is fractured en echelon to the northeast. The best assay from a sample collected by the OGS returned 0.01-0.1% Cu, tr Pb, tr Mn, tr Ni, tr Ti. The best gold analysis returned 0.07 oz/t Au.
