Hudbay Copper Mountain expansion permit: life‑of‑mine and output lens for engineers
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
Hudbay Minerals has secured amended environmental permits from British Columbia’s Major Mines Office for the three-phased New Ingerbelle expansion at the Copper Mountain open pit, extending mine life into 2040 and targeting a 90% increase in copper output via nested pushback pits into the historical Ingerbelle pit. The project is expected to add about 750,000 tonnes of copper, 900,000 oz gold and 5.5 million oz silver from 2027–2037, before low‑grade stockpile re‑handling and closure from 2036–2040. Copper Mountain currently runs a 45,000‑tonne‑per‑day crushing–grinding–flotation plant and produced 22,445 tonnes of copper in 2025.
Technical Brief
- New Ingerbelle is configured as a sequence of nested pushback pits into the historical Ingerbelle void.
- Expansion is forecast to generate over C$11.5 billion in provincial GDP and preserve 800 direct jobs.
- Hudbay reports participation agreements with two First Nations, embedding collaborative oversight into permitting and operations.
- BC has also fast‑tracked three early‑stage projects (including two copper assets), signalling a more permissive permitting stance.
Our Take
Hudbay Minerals also appears in our coverage as a strategic investor in Osisko Metals’ Gaspé copper project in Quebec, suggesting the Copper Mountain and New Ingerbelle copper push in British Columbia is part of a broader Canada-focused copper growth pipeline rather than a single-asset bet.
With Copper Mountain’s life now stretching into 2040 and Newmont’s Cerro Negro gold operation in Argentina extended beyond 2035, Hudbay and Newmont are both locking in long-dated copper–gold exposure, which could influence how they prioritise sustaining versus growth capital across the Americas.
The 90% copper production uplift and preservation of 800 jobs at Copper Mountain align with British Columbia’s recent fast-tracking of other copper and critical minerals projects, signalling that long-life copper operations near established towns like Princeton may see smoother regulatory pathways than greenfield sites.
