In May, Zijin's Kamoa-Kakula copper mine produced 35,856 tons of copper, a monthly high. Monthly copper production corresponds to an annual output of about 430,000 tons of copper.

The Kamoa copper mine produced 34,826 tons of copper in April, producing 71,000 tons of concentrate containing copper in the second quarter of this year and 94,000 tons in the first quarter of this year.

The phase I and II daily processing of 29,366 tons of ore is a new record. This is equivalent to an annual milling rate of 9.8 million tonnes per annum (after accounting for availability). This record far exceeds the increased milling capacity of 9.2 million tonnes per annum following the debottlenecking program of the Phase 1 and 2 concentrators, which was completed in February 2023. Average copper recoveries for the month were 87%, above the Phase 1 and 2 concentrator nameplate recovery rates.

The Kamoa mine is planning the third phase of the expansion project, including the construction of Africa's largest smelter, which can produce 500,000 tonnes of crude and anode copper containing more than 99% copper per year, and is scheduled to start production in the fourth quarter of 2024.
