Minera San Jorge S.A is an Argentine mining company currently developing the San Jorge porphyry copper-gold project. The project consists of an open-pit mine and concentrator in Uspallata, Mendoza province, with an SXEW plant, in the neighboring San Juan province. Measured and inferred resources are estimated at 900,000t of copper and 1.03Moz of gold contained in 194MMT of ore, with an estimated production of 24,000t/y of copper cathodes during 10 years, plus more than 40,000t/y of copper and close to 40,000oz of gold over 16 years. In 2015, Minera San Jorge was acquired from Coro Mining by Russian investment company Aterra Capital and Swiss firm Solway Investment Group. The project is currently halted due to a pending decision by Argentina's Supreme Court relating to the use of toxic substances in the region's mining processes.
