Assay results from shallow drilling have confirmed high-grade gold-silver mineralization at the Huevos Verdes prospect in southern Argentina, reports
The first six angle holes encountered high-grade mineralization along a 400-metre segment of the 2.4-km vein system.
The program is designed to test for continuity of the vein, as outlined by geologic mapping and trenching.
The best interval came from hole 39, which cut 6.3 metres (true thickness) grading 9.74 grams gold and 630.3 grams silver per tonne.
Stepping out 100 metres to the south, holes 38 and 42 cut the vein structure at depths of 30 and 80 metres below the surface, hole 38 hit 7.4 metres grading 2.19 grams gold and 170 grams silver, and hole 42 hit 2.7 metres of 2.17 grams gold and 99.8 grams silver.
Eighty metres north of hole 39, Minera Andes drilled another pair of holes. Hole 40 intercepted the vein at a depth of 46 metres, running 3.85 grams gold and 249.8 grams silver over 4.1 metres (true thickness). At a depth of 99 metres, hole 43 hit a narrower portion of the vein, grading 7.37 grams gold and 769 grams silver over 0.8 metre.
Hole 41 intercepted the vein farther south, with a 2.9-metre interval grading 2.18 grams gold and 175.1 grams silver. Mineralization remains open at depth and along strike.
Overall, the drilling found the vein narrowing slightly at depth, from as thick as 12 metres at the surface to less than a metre at the deepest intersection. However, grade continuity remained consistent.
Minera Andes has completed 22 drillholes, totalling 1,700 metres. Results from the 16 additional holes, including holes drilled on a parallel vein structure to the west and one hole on the El Pluma West target, are pending.
The company also completed geophysical surveys on four other targets, including Saavedra West and Cerro Celular.
The targets are but a few of the many gold-silver prospects in the company’s 92,000-ha El Pluma-Cerro Saavedra project in northwestern Santa Cruz province.
