Toronto-listed Cominco reported a preliminary resource estimate for its polymetallic discovery in the southwestern Yukon.
The deposit was estimated to contain 13 million tonnes grading 5.5% zinc and 1% copper, with silver and gold values of 125 and 1.2 grams per tonne, respectively.
The estimate was based on 40 holes; drilling was spaced on 100-metre centres, except in the southwestern quarter of the deposit where spacing was about 50 metres.
More than half of the reserves may be amenable to open-pit mining; Cominco envisages a yearly production rate of 1 million tonnes.
