Ann: CNQ acquires ATA tailings dewatering technology, page-36

Copper
Work on copper recovery from the Kamoa Kakula flotation tailings was initiated during this reporting period. A series of tests
have been conducted using chemical and physical methods to recover copper units from the flotation tailings.
The ongoing tests will determine the success and economic viability of this approach. If the results prove promising, the scope
of the project will be expanded to demonstrate the technology at a larger scale.
Both mechanical and chemical activation have shown improved outcomes, and the results are currently being evaluated for
potential full-scale applications. This progress represents a significant step towards maximising copper recovery and optimising
resource utilisation in the mining process.
