Chilean privately owned company Minera Amalia has issued an EIA for a US$2.0mn expansion to the Catemu copper processing plant in region V, reopened by the miner in July 2007.
The project entails enlarging the leach pad area, according to the EIA issued to Chile's environmental regulator Conama, which did not provide tonnage data.
Chilean state miner Enami built the Catemu plant in 1973. The operation was privatized into the hands of Minera Catemu in 1982 and ran under that ownership until 1999, when it was halted due to lack of raw materials.
When it was reopened, the plant was slated to run at a rate of some 50,000t/d and produce roughly 5,000t/y of fine copper for eight years.
