El Torno contains a large gold-rich quartz vein system that extends north-south for 14 km and is up to 20 metres wide. The central parts of the system have been worked since the Incas, resulting in about 1 km of underground galleries that are now flooded. The vein system was investigated by Puma Minerals in 1997 who carried out over 2,100 m of drilling. They were followed in 1999 by Peñoles (discoverer of the world’s largest silver mine and Mexico’s largest and richest gold mines) who undertook trenching, grab sampling, and geological surveying as well as a geophysical IP survey. The drilling showed that gold is concentrated in a 2 metre-wide zone on the western side of the main vein. Puma estimated that a 1.3 km length of the vein could have the potential for over 500,000 ounces of gold to a depth of 100 metres or 2 million ounces to a depth of 400 metres at an assumed grade of 10 g/t gold (not NI-43-101 compliant)
