Mar 29, 2007 (Mark Puumala) - This occurrence is based on a reported anomalous zinc assay (8000 ppm) reported from Cominco diamond drill hole ML81-4 (AFRO# 52O11SW0016). The anomalous assay was obtained from material logged as tuffaceous chert and chert that contains 5% medium-grained pyrite as stringers and small lenses in bedding planes. Other lithologies reported in this drill hole included mafic metavolcanics and banded magnetite iron formation. Some pyrrhotite and pyrite mineralization (up to 3% reported for each) was noted in the iron formation horizons. No precious metal assays are reported on the diamond drill log.
