The updated mine plan significantly de-risks Snow Lake's long-term production profile and extends visibility to 2043. Watch for the NI 43-101 technical report due within 45 days, the site visit on October 1, 2026, and future resource-to-reserve conversion updates from the 1.5 million ounces of inferred gold resources.

Executive Summary
Hudbay Minerals released an updated mine plan for its Snow Lake operations, extending the reserve mine life by two years to 2043 (six years total including a prior extension), increasing life-of-mine gold production by 60% to 2.8 million ounces, and raising five-year average annual gold production to 185,000 ounces (+37% vs the 2021 technical report). Mineral reserves increased 38% to 27 million tonnes containing 2.0 million ounces of gold, and mineral resources rose 26% to 21 million tonnes containing 1.5 million ounces of gold. The plan is based on conservative reserve estimates with significant upside potential from resource conversion, the Britannia Gold Project, and other brownfield initiatives.
Key Facts
- Reserve mine life extended to 2043 (two additional years, six total including March 2026 extension)
- Life-of-mine gold production increased 60% to 2.8 million ounces from 1.8 million ounces in the 2021 technical report
- 2026-2030 five-year average annual gold production of 185,000 ounces, a 37% increase from an additional 250,000 ounces over the period vs the 2021 technical report
- Mineral reserves increased 38% to 27 million tonnes containing 2.0 million ounces of gold vs January 1, 2026 estimate
- Mineral resources increased 26% to 21 million tonnes containing 1.5 million ounces of gold vs January 1, 2026 estimate
- 2026-2030 average gold cash costs of $821/oz and sustaining cash costs of $1,379/oz
- 1901 deposit on track for full production in late 2027; Stall Hot Tails Leaching project commissioning expected early 2028
- Talbot and Rail deposits added as mineral reserves for the first time following 2023 Rockcliff acquisition
- Britannia Gold Project identified as potential new anchor deposit with 8.3 million tonnes of inferred resources at 2.87 g/t gold
Financial Impact
60% increase in life-of-mine gold production to 2.8 million ounces; 37% increase in five-year gold production; 38% increase in mineral reserves; 26% increase in mineral resources
Risk Factors
- Execution risk on 1901 development timeline (full production late 2027) and Stall Hot Tails Leaching project (early 2028)
- Commodity price assumptions ($3,600/oz gold long-term) may not hold; lower prices could impact reserve economics
- Permitting and social license required for satellite deposits (Talbot, Rail, WIM, 3 Zone)
- Inferred resources (1.5 million oz gold) are not reserves and may not convert economically
