Statement from Mitsubishi (translated from Japanese) We are aiming to start production in 2030, and since the resources are abundant and the grade of gold contained in addition to copper is high, it is highly economical. In addition, the copper concentrate to be produced is expected to be a clean ore with few impurities, and a long-term stable supply of copper resources is expected until 2057. With this capital participation, we will establish a Technical and Sustainability Committee with WRN, and will strive to further promote the project while confirming future progress.(source: Mitsubishi Materials Japanese website/ press release)
