Insights
Hudbay secures transformative $600M Mitsubishi partnership for Copper World, significantly de-risking the project while retaining 70% ownership and improving financial returns.
Hudbay Minerals has struck a $600 million strategic partnership with Mitsubishi Corporation, selling a 30% stake in its Copper World project in Arizona. This transaction represents a major de-risking milestone that validates Copper World as a world-class copper asset.
The deal structure is particularly favorable for Hudbay, with $420 million payable at closing and $180 million within 18 months. Mitsubishi will also contribute its pro-rata 30% share of all future development costs. According to the company, this partnership increases Hudbay's levered project IRR to approximately 90% based on pre-feasibility study estimates - an extraordinary return figure that reflects both the project's intrinsic value and the favorable deal terms.
Critically, this transaction significantly reduces Hudbay's capital burden. The company now estimates its remaining capital contribution at only $200 million, with no payments required until 2028 at the earliest. This provides substantial financial flexibility as Hudbay advances toward a final investment decision in 2026.
Complementing the Mitsubishi deal, Hudbay has agreed to enhance its streaming agreement with Wheaton Precious Metals. The revised terms include an additional contingent payment of up to $70 million tied to future mill expansions, while amending the ongoing precious metals payments from fixed pricing to 15% of spot prices - providing upside exposure in rising metals markets.
With these agreements, Hudbay has effectively completed its "3-P" (prerequisite) financing plan for Copper World. The company already reports $600+ million in cash and a net debt to EBITDA ratio of just 0.4x as of June 30, 2025.
Copper World's projected annual production of 85,000 tonnes over a 20-year mine life represents a significant addition to America's critical minerals supply chain. The fully-permitted project is expected to create over 1,000 construction jobs and 400 direct operational positions.
The involvement of Mitsubishi - which has investments in five of the world's top twenty copper mines - provides strong external validation of both the project's quality and Hudbay's technical capabilities. With definitive feasibility study completion targeted for mid-2026, Hudbay is accelerating detailed engineering and long-lead procurement activities.
- Secures a premier long-term strategic partner in Mitsubishi, which has a long history of joint venture partnerships in the highest quality copper mines globally
- Mitsubishi's strategic partnership validates the attractive long-term value of Copper World as a world-class copper asset and endorses the strong technical capabilities of Hudbay
- Facilitates approximately
$1.5 billion investment in the U.S. critical minerals supply chain to deliver an anticipated 85,000 tonnes of "Made in America" copper production annually for 20 yearsi - Copper World is expected to create more than 1,000 jobs during project construction with 400 direct jobs and up to 3,000 indirect jobs once in full production
- Mitsubishi's initial investment of
$600 million and pro-rata equity capital contributions provide significant financial flexibility by reducing Hudbay's estimated share of the remaining capital contributions to approximately$200 million based on PFS estimates - Defers Hudbay's first capital contribution to 2028 at the earliest based on PFS estimates
- Increases levered project IRR to Hudbay to approximately
90% based on PFS estimatesii - Agreed on terms for an enhanced precious metals stream with Wheaton which contemplates up to
$70 million contingent payment that recognizes long-term potential of Copper World in addition to initial$230 million stream deposit - Transaction would achieve the key funding elements in Hudbay's 3-P prudent financing framework for the development of Copper World

About Copper World
The
In September 2023, Hudbay released its enhanced PFS for Copper World reflecting the results of further technical work on Phase I of the project. Phase I has a mine life of 20 years, which is four years longer than the Phase I mine life that was presented in the PEA, largely due to an increase in the capacity for tailings and waste deposition as a result of optimizing the site layout. Phase II is expected to involve an expansion onto federal lands with a significantly longer mine life and enhanced project economics. Phase II would be subject to the federal permitting process and was not included in the PFS results.
Based on the PFS, Phase I contemplates average annual copper production of 85,000 tonnes over a 20-year mine life, at average cash costs and sustaining cash costs of
