Minera Santa Cruz has commissioned a feasibility study of its San Jose gold-silver project in southeastern Argentina.
The Argentine company is 51%-owned by Mauricio Hochschild & Cia. and 49% by Spokane, Wash.-based
Ten gold-silver targets have been outlined on the property, which comprises 400 sq. km in Santa Cruz province, about 230 km southwest of Comodoro Rivadavia.
The most advanced target is the Huevos Verdes quartz vein system, which in 2002 was estimated to contain an inferred resource of 3.5 million tonnes grading 235.3 grams silver and 2.72 grams gold per tonne, based on a cutoff of 50 grams silver.
The en echelon quartz veins trend north-northwest over at least 2.2 km. The mineralized veins are up to 11 metres wide and crosscut massive and fragmental andesite. The veins are locally covered by basalt and sediments.
Two 45-inclined shafts are under construction, and drilling, bulk sampling and geotechnical studies are under way on two underground levels.
A 28-km all-weather road and a bridge were constructed from a paved highway to the site, where 100 people can be accommodated.
Recent drilling 2 km northeast of Huevos Verdes resulted in grades as high as 53.75 grams gold and 1,711.6 grams silver per tonne over 1 metre.
The feasibility study will be conducted by MTB Project Management Professionals of Denver, Colo.
