ZINC-LEAD: Canadian Zinc, Buchans Minerals study central mill facility

NEWFOUNDLAND – Canadian Zinc Corp. of Vancouver and Buchans Minerals Corp. (a subsidiary of Toronto-based Minco Plc) are researching the possibility of building a central mineral processing plant to treat material from their respective zinc-lead properties.

Buchans owns the Lundberg deposit and the former Buchans mine. It has an indicated resource of 23.4 million tonnes at 1.41% Zn and 0.60% Pb, plus copper, silver and gold. The inferred portion is 4.3 million tonnes at 1.29% Zn and 0.54% Pb.

Canadian Zinc holds a number of volcanogenic massive sulphide deposits, including South Tally Pond (adjacent to Teck’s Duck Pond mine), Tulks South, Long Lake, and Lake Douglas plus the former Victoria mine. Most of the properties have indicated and inferred resource estimates, and there are four additional deposits.

Canadian Zinc and Buchans Minerals want to determine the technical and economic possibilities of a shared mill that could significantly enhance the viability of mining at their varied properties. The concept is based on pre-concentrating the ore at the mine sites and trucking it to the central mill where it would be treated either simultaneously or sequentially. The project has been awarded $535,000 from GeoExplore, an industry led R&D demonstration program. Total cost of the Canadian Zinc-Buchans study is $735,000.
