Taseko Starting Up Florence Copper Project in Arizona
At full capacity, the Florence facility will produce an average of 85 million pounds per year (lb/y) of LME Grade A copper cathode over an operating life of about 21 years. The Florence deposit consists of a large porphyry copper sulphide system overlain by a thick and intensely fractured oxidized layer. The oxidized zone is saturated with ground water that is separated from the upper drinking-, agricultural-, and industrial- use aquifer by a thick layer of dense, low-permeability clay and separated from the deep groundwater by the relatively impervious sulphide system. This unusual, perhaps even unique, geological and hydrological combination makes the oxidized zone ideal for in-situ copper recovery.
