Vancouver — Metallurgical testing on material taken from the Huevos Verdes gold-silver vein in southern Argentina has resulted in encouraging recoveries for 49-51 partners
The vein is part of the San Jose project, where an ongoing feasibility study, slated for completion in late 2004, is aimed at developing reserves in the high-grade veins.
Tests show that 96% of the gold is recoverable using both chemical leach and flotation. Silver recoveries are 93% and 95.7%, respectively.
Four veins with a strike of about 32 km have been identified on the project. The Huevos Verdes vein has a known strike length of 5 km, less than half of which has been drill-tested. The mineralization outlined remains open at depth and along strike.
Gold and silver mineralization is epithermal and hosted in a series of low-sulphidation, en echelon quartz veins up to 11 metres wide.
Indicated resources at Huevos Verdes stand at 1.5 million tonnes grading 212 grams silver and 2.6 grams gold. There is an additional inferred resource of 2.1 million tonnes of 252 grams silver and 2.8 grams gold.
Minera Andes has been exploring for minerals in Argentina since the mid-1990s. The company has a dozen projects in the country containing gold, silver and copper targets.
