30 Second Briefing
Agnico Eagle Mines will invest C$14 billion in Ontario by 2030, backed by the province’s new “One Project, One Process” permitting regime that targets approvals for advanced exploration and mine development within two years. About C$2 billion is earmarked for the Detour Lake underground expansion and the Upper Beaver gold-copper project, both >C$1 billion builds, adding up to 1,600 jobs and nearly C$5 billion to GDP. Detour Lake’s underground mine is designed to extend life to 2054, while Upper Beaver is planned as a 210,000 oz/y gold and 3,600 t/y copper operation over 14 years.
Technical Brief
- Ontario’s “One Project, One Process” framework centralises all permits and authorisations into a single, coordinated stream.
- The 1P1P regime sets a hard cap of two years for advanced exploration and mine development approvals.
- Additional “red tape reduction” measures are being prepared to shorten permitting for expansions of existing mines specifically.
- Detour Lake, ~900 km north of Toronto near the Quebec border, is Canada’s largest gold mine by reserves.
- The Detour Lake underground expansion is budgeted at about C$1 billion beneath the current open pit.
- Upper Beaver, ~20 km east of Kirkland Lake, will combine underground and open-pit mining with an on-site plant.
- Upper Beaver’s redevelopment targets a modern gold–copper operation on the footprint of a historic mine.
- Agnico’s growth plan also depends on expansions at Canadian Malartic and new builds at Hope Bay and San Nicolas.
Our Take
Agnico Eagle Mines’ plan to lift gold output by 20–30% by 2030 in Ontario sits on top of record 2025 reserves of 55.4 million oz reported in our coverage, signalling that Detour Lake and Upper Beaver are being used to convert a strong reserve base into long-duration, tier-one production rather than just incremental growth.
