Overall construction progress of RP2.0 has exceeded 90%, and the project will double RPZ's production, with completion expected by the end of 2026, followed by a gradual ramp-up. The project will increase annual ore production from 700,000 mt to 1.4 million mt, with average annual zinc equivalent production rising to 170 million pounds.

On May 13, 2026, Nexa Resources announced that an accident occurred in the morning at the Cajamarquilla zinc smelter in Peru, triggering a fire. The fire has been brought under control, and operations have been suspended. It was reported that no fatalities resulted from the incident. Some infrastructure at the smelter sustained damage.
