The first phase of metallurgical testing at the Omni polymetallic project in the Yukon is complete, reports Wheaton River Minerals (TSE).
At Lakefield Research, a mineral-processor near Peterborough, Ont., a bulk concentrate was produced under the direction of consulting firm Melis Engineering. Melis estimates that, in a continuous flotation operation, recoveries will be about 92% for gold and 94.5% for silver. The test concentrate graded 43 grams gold per tonne, 4,229 grams silver, 0.41% copper, 9.54% lead, 10.4% zinc and 18.5% arsenic.
The second phase involves about 12 weeks of bio-leach tests at Triton Development in Vancouver, B.C. (The concentrate is dissolved in solution, the dissolution being aided by bacterial action.) The company is also canvassing smelters around the world for potential sales of lead or zinc concentrate. In other news, Wheaton River is negotiating with a foreign mining company to buy the controlling interest in a producing North American gold mine.
