The Group’s principal business activities are the production of copper cathode at its Kounrad operationsin Kazakhstanand the production of lead, zinc and silver at its Sasa operations in North Macedonia. CAML owns 100% of the Kounrad SX-EW copper project in Kazakhstan and 100% of the Sasa zinc-lead mine in North Macedonia. The Company also owns two further operations which are currently held for sale and this includes 80% of the Shuak copper exploration property in northern Kazakhstananda 75% equity interest in Copper Bay Limited, which is a private company that has conducted a definitive feasibility study at its copper project in Chañaral Bay, Chile. |

Copper Bay is a private company in which CAML has a 75% interest and owns 100% of the project at Chañaral Bay, in the Atacama region of Chile, some 1,000km north of Santiago.
Summary:
Currently, it is envisaged that the resource will be mined using dredging operations feeding the tailings product to the process plant.

Summary:
Metallurgical test work indicates that the most effective means of extracting the copper from the tailings is by initial acid leach to produce a copper cathode product followed by froth flotation of the leach tails to produce a clean copper concentrate. Indicative metallurgical recovery from the PFS test work is 72.8%.
The DFS utilises a dredging operation to recover the copper tailings, a solvent extraction and electro-winning (SX-EW) plant to produce copper cathode and a flotation circuit to produce a copper in concentrate product that could be marketed to nearby smelters.
