Berkara
An operating mining and metallurgical complex: open-pit copper mining, heap leaching and cathode copper production by SX-EW. The group has participated in the project as managing partner since 2026.

SX-EW plant design capacity
Open-pit mining, two operating pits
Life-of-mine average
About 300 employees
1 Design capacity; actual output depends on ore grade and the mining schedule.
An operating business
The complex was built and commissioned by the previous owners: ore mining began in 2021 and the SX-EW plant was commissioned in 2022. Copper is produced and sold every month.
Oxide and mixed ores are stacked on heap-leach pads. Copper is recovered from solution by solvent extraction and electrowon as cathodes (SX-EW). Low-grade (off-balance) ore from the dumps is also fed to the process.
The group entered the project in 2026 as managing partner: it forms the management team, controls the budget and launches growth projects.
