Name(s) in local language(s):
Mina San Santiago


This mine formerly called "Solitaria" is in the Quebrada de Cumichango, located about 35 km north of Jagüe city and 280 km to the NW of Chilecito city in General Sarmiento Department.

The area of this mining property consists of amphibole, quartzites, mica, etc..., crystalline schists belonging to the Precambrian; pegmatites and lamprophyre containing ore can be seen in them.

The site consists of a generally NE-SW vein with a dip of 45 ° W, which has a known length of several tens of meters and a thickness of a few decimetres. Within the massive granular calcite, there are lenticular bodies rich in Nickeline - the main ore-, which is closely associated the Pitchblende in thin black-grey films, as well as small proportions of Sphalerite, Pyrite, Chloantite, Galena and Chalcopyrite.

The structure of the grain in the areas of the Nickeline is breccia.
The deposit is epithermal and has no apparent link with visible eruptive rocks of the area.
The content of selected minerals is 15-20% of Ni with 1.0-1.2% U3O8.
