Taseko Mines Limited has entered a strategic partnership with Mitsui & Co. (U.S.A.) Inc. for the development of the Florence Copper project in Arizona. Mitsui will invest an initial US$50 million, channeled into the construction of the commercial production facility. This investment will be via a copper stream agreement on 2.67% of Florence Copper's output. Mitsui can invest an extra US$50 million within three years after the facility's construction, earning a 10% equity interest. If Mitsui chooses this option, the Copper Stream ceases. The companies have also struck an offtake deal for 81% of the copper cathode from Florence in the early production years. This collaboration aims to promote 'green copper' sales in the U.S., given Florence Copper's potential as North America's least carbon-intensive copper producer. The partnership's future vision includes possible efforts to establish Florence Copper as a zero-carbon copper producer. Transaction specifics include Mitsui's first US$10 million deposit following Florence Copper's Underground Injection Control permit acquisition, with quarterly US$10 million installments. If Mitsui chooses the Equity Option, the initial offtake agreement will transform into a marketing agency agreement. If the Copper Stream isn't converted to equity, Taseko can buy-back the full Copper Stream, which ends after delivering 40 million pounds of copper. Mitsui's offtake then diminishes to 30% until the Copper Stream deposit is zeroed.
