Mitsui & Co - Tokyo-based conglomerate - Subsidiary Mitsui USA enters into agreements with Florence Copper LLC for copper cathode offtake and an equity conversion right. Says Florence plans to produce low-carbon copper cathode in Arizona, and Mitsui will pay USD50 million to cover part of the development costs. Says Florence plans to produce copper using the in-situ recovery for extracting the metal from underground deposits. This method will "enable mining operation with carbon emissions approximately 80% lower compared with conventional copper mining, and also a low environmental burden, since no shovels, trucks, or other heavy machinery are used to extract copper". Expects construction to take 18 months, and then production will start.
Florence is a subsidiary of Taseko Mines Ltd, a mid-tier copper producer in Canada, which is listed in Toronto, New York and London.
ISR is a method in which diluted acidic solution is injected into the ground to dissolve copper minerals in situ. The resulting solution is then pumped up to the surface.
