Yacimiento Urcal


Guandacol area with elevation 1383 metres above sea level:
Are a series of uraniferous events hosted by continental sediments of the Panacan training (Carboniferous). In "Sonia" mineralization consists of nodules, guides and lenses "pitchblende" together with sulfides, and secondary minerals U and Cu. In the "Martita" ore also consists of nodules, guides and lenses "pitchblende" along with chalcocite, bornite, chalcopyrite, calcite, and different secondary uranium minerals. While appears as a fill of small fractures in the sandstone, the massive bodies notes replacement of remains of tree trunks. Both mines recorded "pitchblende" with high content of Zr.
In "El Pedregal" mineralization is composed of "pitchblende" scarce sulphides and carbonaceous fossils.

Deposit of Vein Forms of the Sector Urcal:
in this sector, it houses control sedimentary deposits, discovered a series of uraniferous bodies housed along a fracture line, close to contact Ordovicic limestones with carbonated sandstones (site Urcal). After studies, estimated that they may acquire economic interest, having recovered from the exploratory work more than 200 tons of ore selected with average of 1.50% U3O8. The reasonable prospect of development of the district are estimated at 450 tonnes of U3O8 and their potential in 950 tonnes of U3O8. Primary mineralization consists of: Calcite, Limestone and Carnotite, Tyuyamunite.
Uranium Deposit near of Guandacol, La Rioja.

In this district that houses control sedimentary deposits, discovered a number of uranium bodies housed along a fracture line, near the contact of ordovicic limestones with carbonated sandstones. Exploratory works recovered more than 200 tons of selected mineral, with average grade of 1.50% of U3O8. The reasonable possibilities of development of the district is estimated at 450 tonnes of U3O8 and their potential in 950 tonnes of U3O8.
