Greenstone to test mill at Millie Mack

The property is in southeastern British Columbia, about 18 miles east of the town of Burton.

The mill is to be used in conjunction with a test-mining program for determining gold grades, definitive metal recoveries and production costs at the potential open pit property. Up to 4,000 tons of material will be processed from nine separate mineralized zones within a flat-laying bed of carbonaceous argillite.

According to Greenstone President Ian Park, the program has three objectives.

“First, we want to establish two million tons of mineable reserves with a grade exceeding 0.15 oz per ton, and a stripping ratio of less than 2:1.”

Park believes a tonnage figure of that size would justify a 1,500- ton-per-day operation at the site. “Second, we want to confirm, and if possible, improve upon the latest testing which indicates a gold recovery of 92.5%, and a silver recovery of 86.7% in a bulk flotation concentrate.”

The company’s third objective is to assess production costs and methods with a view to reducing the currently estimated economic break- even grade of 0.05 oz gold (or equivalent). The first results from the new test-mining program are expected in February, the company said.

Elsewhere, Greenstone is planning a spring work program to define drill targets on its Tiger polymetallic property, 28 miles north of Cranbrook, B.C.

The property, which hosts copper-gold-silver occurrences in the Jubilee limestone formation, is 50% owned by Dragoon Resources. The most recent assays range up to 24.8% copper, 62.4 oz silver and 0.337 oz gold. “Even the low-grade samples average more than 1% copper and 0.02 oz gold,” according to Park.
