Hudbay Minerals Inc. and Mitsubishi announced a final investment decision to proceed with construction and development of Copper World. Hudbay owns 70% of the project and Mitsubishi owns 30%. First production is targeted for the second half of 2029.
The partners approved approximately $2,070 million in initial growth capital expenditures, net of equipment financing, in 2026 dollars and on a 100% basis. Initial capital is expected to be funded by Mitsubishi’s $600 million initial joint venture equity investment, Wheaton Precious Metals Corp.’s $230 million deposit for the existing precious metals stream, and approximately $650 million in anticipated project-level debt financing. The balance is expected from pro-rata equity capital contributions, which are not expected to be required until 2028. Hudbay expects to fund its share from existing cash and liquidity and projected free cash flow from its other operations. All dollar amounts are U.S. dollars.
The base case contemplates a 15-year mine life using mineral reserves and requiring only state and local permits. The extension case contemplates a 37-year mine life using only measured and indicated mineral resources; mining would extend onto federal lands in year 10, subject to obtaining federal permits.
Hudbay Minerals Inc. (HBM) reported a definitive feasibility study for its 70%-owned Copper World project in Pima County, Arizona. The selected Base Case remains within the patented claims and private landholdings and relies on state, county and local permits. It models a 15-year mine life plus two years of pre-stripping; proven and probable reserves total 390.4 million metric tonnes at 0.47% copper, estimated as of August 1, 2026.
The plant is designed to ramp to 60,000 short tons per day over the first seven months of Year 1, with planned expansion to 90,000 short tons per day in Year 5; an in-pit crushing and conveying system is scheduled for Year 4. Major permits for construction and start of operations have been issued, while modifications are required for the IPCC, throughput expansion and filtered tailings facility. The alternative Extension Case models a 37-year mine life plus two years of pre-stripping; it is not the selected option and would require federal permits before Year 10. It uses measured and indicated mineral resources, which are distinct from mineral reserves.
Hudbay Minerals Inc. (HBM) and Mitsubishi formally approved the final investment decision to build and develop Copper World, a 70%-owned Arizona project, with first production targeted for the second half of 2029. The Base Case has a 15-year mine life, requires only state and local permits, and projects average annual copper production of 102,000 tonnes over its first 10 years. Initial growth capital is $2.07 billion ($1.84 billion net of the precious metals stream deposit). At $5.00 per pound copper, the Base Case estimates after-tax net present value (8%) of $1.2 billion and a 17% internal rate of return; all major permits for construction and initial operations have been obtained.
The Extension Case contemplates a 37-year mine life, with mining onto federal lands in year 10 subject to federal permits, and annual production of 117,000 tonnes in years 11–20. At $5.00 per pound copper, it estimates after-tax net present value (8%) of $2.5 billion and a 19% internal rate of return. Hudbay's expected project capital contributions are approximately $500 million, with contributions not required until 2028.
Hudbay Minerals Inc. (HBM) updated the reserve-based mine plan for its Snow Lake operations in Manitoba, extending the proven and probable reserve mine life by two years to 2043. Together with the four-year extension announced in March 2026, Snow Lake’s reserve mine life has gained six years. As of September 1, 2026, reserves total 27.0 million tonnes containing approximately 2.0 million ounces of gold, an increase of 7.5 million tonnes and 124,000 ounces versus estimates dated January 1, 2026.
The plan projects average annual gold production of 185,000 ounces from 2026 to 2030, 37% more total gold than the same five-year period in the 2021 technical report. Life-of-mine gold production is projected at 2.8 million ounces, up 60% from 1.8 million ounces in the 2021 report; this comparison includes actual production since 2021. The updated plan’s five-year average gold cash costs are $821 per ounce, and average sustaining cash costs are $1,379 per ounce.

Hudbay highlights a copper growth pipeline that could increase annual copper production from approximately 125,000 tonnes to more than 250,000 tonnes by 2030 and later to over 350,000 tonnes with staged Cactus development. The company also points to potential operating synergies between Copper World and Cactus, including shared engineering resources, use of Copper World sulphuric acid to leach Cactus oxide ore, and an estimated $5–$10 million in annual corporate synergies.
