Key Takeaways
- Cariboo Gold has 5.3 Moz of Measured & Indicated resources in a historic gold district of central BC, with a completed feasibility study.
- The FS demonstrates an after-tax IRR of 22% and NPV(5%) of CAD$1.1B at US$2,000/oz gold materially better at current prices above US$3,200/oz.
- BC Environmental Assessment Certificate is expected by Q3 2026; a construction decision follows in Q4 2026.
- Management team has deep ties to Osisko Mining, which has a track record of building and monetizing large-scale gold projects.
British Columbia’s Cariboo region was one of the world’s great gold rush destinations in the 1860s, and the underlying geology has remained compelling for professional geologists ever since. Osisko Development Corp (ODV.V) is advancing the Cariboo Gold project with 5.3 million ounces of M&I resources at 4.0 g/t gold toward what would be one of BC’s most significant new gold mines in a generation.
The Resource and Geology
Cariboo Gold is centred on the Quesnel Trough in central BC, a prolific gold-bearing terrain that has historically produced millions of ounces. The project’s 5.3 Moz Measured & Indicated resource at ~4.0 g/t gold is hosted in shear-hosted quartz vein systems amenable to underground mining. The high grade compared to typical BC gold project grades of 1.5–2.5 g/t is a significant economic advantage. An additional 1.1 Moz of Inferred resources provides conversion upside through infill drilling.
Feasibility Study Economics
The November 2025 feasibility study outlined a 5,000 tpd underground operation with a 12-year initial mine life. At US$2,000/oz: after-tax IRR of 22%, NPV(5%) of CAD$1.1B, initial capex of CAD$650M, and AISC of approximately US$1,200/oz. Annual steady-state free cash flow of approximately CAD$180M implies a 3.6-year payback. At current gold prices, the payback period compresses to approximately 2 years and the IRR approximately doubles to ~38%.
BC Permitting: Status and Timeline
The BC Environmental Assessment Office completed its technical review in May 2026. Osisko received draft EA certificate conditions in June, with a final EA Certificate expected Q3 2026. Following receipt of the EA Certificate, a Mines Act permit (approximately 6 months) is required before construction. Impact and Benefit Agreements have been signed with two of three First Nations groups; negotiations with the third continue.
Financing and M&A Considerations
The CAD$650M initial capital plan combines approximately CAD$400M of project debt, CAD$100M of royalty/streaming financing, and CAD$150M of equity. Osisko Mining Corp holds a strategic interest and provides credibility and potential backstop support. At current gold prices with permitting nearing completion, Cariboo Gold has attracted M&A speculation Agnico Eagle, B2Gold, and Kinross are among the majors understood to have evaluated the asset, though no formal process has been announced.
| Cariboo FS Metric | Base Case (US$2,000/oz) | Current Price (~US$3,200/oz) |
|---|---|---|
| After-Tax NPV (5%) | CAD$1.1B | ~CAD$2.1B |
| After-Tax IRR | 22% | ~38% |
| Initial CapEx | CAD$650M | CAD$650M |
| AISC | US$1,200/oz | US$1,200/oz |
| Annual Production | ~185,000 oz/yr | ~185,000 oz/yr |
| Mine Life | 12 years | 12 years |
| Payback Period | 3.6 years | ~2.0 years |
The Bottom Line
Osisko Development’s Cariboo Gold project is one of BC’s most advanced large-scale gold development stories, and the current gold price environment has transformed its economics from attractive to exceptional. The EA Certificate (expected Q3 2026) is the critical near-term catalyst, allowing management to finalize financing and announce a construction decision. At current gold prices, the project’s NPV at US$3,200/oz represents a significant premium to the current enterprise value the classic development-stage discount waiting to close.
