Hudbay Secures Permit to Boost Constancia Mine Capacity to 34M Tonnes
Event summary
- Hudbay received regulatory approval from SENACE to increase Constancia mine's mill throughput capacity to 34M tonnes per annum, up from 31M.
- This is the fifth environmental permit amendment for Constancia since 2026, following a previous increase to 31M tonnes in March 2026.
- The approval allows operational flexibility of up to 10% above nominal daily capacity under Peru's regulatory framework.
- Permit also approves mine plan optimization and extends Constancia's operational life with improved tailings and water management infrastructure.
The big picture
Hudbay's permit expansion aligns with its strategy of continuous operational improvement in Peru's critical minerals sector. The move comes amid growing demand for copper and increasing regulatory scrutiny on environmental sustainability in mining operations. This approval positions Hudbay to potentially increase production while maintaining compliance with Peruvian environmental standards.
