Kamoa-Kakula Phase 1 concentrator plant fully operational

The Kamoa-Kakula Phase 1 concentrator plant is fully operational. Ivanhoe Mines made the announcement and said the plant’s commissioning is well advanced, and preparation for final performance tests is underway.

First truckloads of copper concentrate were delivered to a local smelter on June 1, 2021, with concentrate dispatch continuing daily. To date, more than 10,500 dry metric tonnes of concentrate have been delivered to the local smelter, and first blister copper ingots have been received.

First ore was fed into the concentrator plant on May 20 and the start of copper concentrate production occurred on May 25, several months ahead of schedule. As of June 30, 313,000 tonnes of ore grading 4.85% copper had been conveyed to the run-of-mine (ROM) stockpile. The team currently is preparing for the final plant performance tests, which will conclude the C4 (or “hot”) commissioning activities. Feed grades are expected to increase during the month of July.

Arm’s-length commercial terms

On June 9, Ivanhoe Mines announced that Kamoa Copper SA had signed copper concentrate and blister copper off-take agreements, on competitive arm’s-length commercial terms, with CITIC Metal (HK) Limited (CITIC Metal) and Gold Mountains (H.K.) International Mining Company Limited, a subsidiary of Zijin Mining Group, for 50% each of the copper products from Kamoa-Kakula’s Phase 1 production. The company also secured all necessary authorizations to commence exports of copper products from the Kamoa-Kakula mine to international markets.

A total of 338,000 tonnes grading 4.59% copper was mined in June and comprised 295,000 tonnes grading 4.76% copper from the Kakula Mine, including 66,200 tonnes grading 7.71% copper from the mine’s high-grade centre, and 43,000 tonnes grading 3.43% copper from the Kansoko Mine.

Overall copper grades were slightly lower than the previous month, in part due to the requirement to feed lower-grade material directly to the plant during commissioning. The project’s pre-production surface stockpiles now contain approximately 3.4 million tonnes of high-grade and medium-grade ore at an estimated, blended average of 4.78% copper.

Contained copper in the stockpiles at the end of May now totals more than 162,000 tonnes (the current copper price is approximately US$9,430 per tonne). As the plant ramps up to full Phase 1 design capacity, and the mine towards Phase 2 production capacity, the surface stockpiles are expected to continue to build at a reduced rate.
