Nexa Resources is gradually resuming operations at its Cajamarquilla smelter in Peru following an incident on May 13, 2026. Electrolysis lines are fully operational, and one casting line is producing zinc bars, with the remaining lines expected to restart by mid-June. The company estimates a production impact of approximately 7,000 tonnes of refined zinc in Q2 2026, representing about 2% of annual production. This shortfall is expected to be recovered during the second half of the year.
