Capstone Copper, a Canadian company, restarts Chile's Mantoverde Mine while the strike continues

Capstone Copper Corp. resumed its operations at the Mantoverde Copper and Gold Mine in northern Chile despite a strike by a union that represents nearly 22%.

In a filing to the Australian stock exchange dated 1 February, the company reiterated that it expected to continue operating at a level of 50% to 75% normal production throughout this strike.

The shares of Capstone Australia listed depositary receipts fell as much as 4.5 percent to A$15.810 per day, their lowest levels since January 23.

The decision to resume operations was made following a Chilean Court ruling that authorized the removal of striking workers last week from a desalination plant, which supplies water to the mine. This is a vital resource for the day-today operations.

Strike began

In January, after the negotiations with Union No. 2 of Mantoverde broke down. The latest offer of payment from the company was rejected by the unionized workers, leading to the current impasse.

Capstone stated that it is open to dialogue with the union in order to resolve the dispute.

Union No. Union No. The union is leading the strike.

The main conflict is centered on Mantoverde’s desalination facility on the coast, about 40 km (25 miles), from the mine.

The company reported on January 18 that individuals had entered the desalination plant, interfering in the electrical system of the?plant and causing a disruption in the water supply.

The mine was forced to use its own reserves and halt certain operations, including the sulphide-processing. It warned that further closures may occur if this situation persists.

Chile is the world's largest copper producer.

Grabber

Santiago has been forced to consider "unprecedented" water rationing due to the deepening droughts.

Water shortages are intensifying tensions between miners, who traditionally depend on water sources from the continent like rivers, lakes and reservoirs.

Mantoverde will produce 62,308 tonnes of copper concentrate in 2025 and 32,807 tonnes of copper cathodes. This is about 0.4% global production.
