CAPSTONE GOLD CORP.: INITIAL RESOURCE ESTIMATES FOR COZAMIN COPPER-SILVER-ZINC MINE, ZACATECAS STATE, MEXICO
Capstone Gold Corp. has released its initial resource estimates for Cozamin copper-silver-zinc mine.
Highlights
Initial independent resource estimate was completed for Cozamin copper-silver-zinc mine.
Cozamin mine resource estimate at a 1.5 per cent copper equivalent (1) cut-off grade totals:
measured category -- 650,000 tonnes containing 26.1 million pounds of copper and 1.8 million ounces of silver;
indicated category -- 2.74 million tonnes containing 103.3 million pounds of copper and 6.2 million ounces of silver; and
inferred category -- 4.2 million tonnes containing 139.8 million pounds of copper and 7.8 million ounces of silver.
An initial current resource estimate for the Cozamin mine has been completed by independent qualified person Gary H. Giroux, PEng, MASc, of Giroux Consultants Ltd., of Vancouver, B.C. The resource estimate was based on a three-dimensional geologic model of the mineralization using over 25,000 metres of drilling in 37 surface and 66 underground core holes. Also, 48 underground channel samples were included in the model. Grades for the model were estimated using ordinary kriging procedures and mineralization was composited on two-metre intervals with high-grade samples capped using lognormal probability plots.
The resource estimate includes measured and indicated resource of 3.4 million tonnes grading 73.5 grams per tonne silver, 1.7 per cent copper, 1.4 per cent zinc and 0.7 per cent lead, and containing 129.4 million pounds of copper and 8.0 million ounces of silver at a 1.5 per cent copper equivalent cut-off grade. The inferred resource totals 4.2 million tonnes grading 57.7 g/t silver, 1.5 per cent copper, 1.5 per cent zinc and 0.3 per cent lead containing 139.8 million pounds of copper and 7.8 million ounces of silver at a 1.5 per cent copper equivalent cut-off grade.
The following summary tables 1, 2 and 3 show overall project resource estimates at incremental copper equivalent cut-offs of 1.2 per cent, 1.5 per cent and 2.0 per cent respectively. Copper equivalent grades are based both on assumed metal prices and estimated recoveries based on extensive metallurgical test data from the Cozamin mine. |
