Nexa Resources Resumes Cajamarquilla Smelter Operations After Fire Incident

Key Facts

In a move that strengthens industrial metal supply stability, Nexa Resources has officially resumed operations at its Cajamarquilla smelter following a temporary shutdown caused by a fire incident. Zinc production lines have restarted after the completion of necessary repairs and safety assessments. The company expects to fully recover the lost output resulting from this disruption by 2026, signaling management's confidence in the facility's return to full capacity.

This resumption comes at a critical juncture for the global zinc market, as major peers such as Glencore and Teck Resources have faced supply chain challenges in recent periods. Per market data, the return of the Cajamarquilla facility—one of the world's largest zinc smelters—is expected to alleviate pressure on global inventories. Previous earnings reports indicate that the mining and smelting segment remains the core driver of Nexa’s growth, making this restart vital for maintaining profit margins.
