This is a direct consequence of Kamoa-Kakula being the highest-grade major copper mine globally. However, we are leaving a significant amount of copper behind… copper that this planet so desperately needs right now for our energy transition. \"If we can recover this copper, the production profile following the Phase 3 expansion could be in excess of 700,000 tonnes per annum. Not only would this provide additional revenue and cash flow, but also it would reduce even further our tailings footprint. \"We are targeting total copper recoveries in the mid-nineties from this breakthrough as well as from the other concurrent workstreams. Our experienced team, with a proven track record of execution and delivery, are leaving no stone unturned to improve the efficiency of extraction from this incredible endowment.\" Kamoa-Kakula is the highest-grade major copper mine; further improvement in recoveries can result in significantly increased copper productionIn 2022, Kamoa Copper's process engineering team, together with a number of internationally recognized external metallurgy specialists, initiated work to investigate ways to economically recover additional copper units from the tailings stream of the Phase 1 and 2 concentrators. During 2022, the Kamoa-Kakula Copper Complex milled approximately 7.1 million tonnes of ore at an average feed grade of 5.5% copper, producing 333,497 tonnes of copper in concentrate. Based on the metallurgical recovery of 8...
