Golden Dawn Minerals Inc. announced that an updated Mineral Resource Estimate has been completed for the J&L Project, with 1.35 million gold equivalent ounces in the Measured and Indicated categories and 1.08 million gold equivalent ounces in the Inferred category. J&L is therefore one of the largest undeveloped gold Mineral Resources in western Canada. J&L is an advanced stage project located 35 km north of Revelstoke, BC. The project assets include a rail siding and load-out facility for the Canadian Pacific Railway in Revelstoke, and a fully functional 40-man camp as well as a large shop and office facility located at the property, with two mine portals that access 3.1 km of underground mine workings, and a fleet of formerly utilized underground mining equipment. The updated Mineral Resource Estimate includes the Main, Yellowjacket, Hanging Wall (HW) and Footwall (FW) Zones. The most significant are the Main, Footwall and Yellowjacket Zones. The Main Zone extends over 3 km on surface and has been drill-defined over 1.5 km along strike and 850 m down dip and remains open for expansion. In general, the zones consist of gold-silver-lead-zinc-bearing sulfides.
