August 2025 — Hudbay Minerals has announced a landmark agreement: Mitsubishi Corporation will acquire a 30% stake in the Copper World project in Arizona through a $600 million investment. This strategic collaboration accelerates the U.S. copper supply chain while significantly easing Hudbay’s financing burden.
Key Highlights
- Deal Structure: Mitsubishi will pay $420 million upfront at closing, with an additional $180 million due within 18 months. The financing moves Hudbay’s own initial capital contribution to as late as 2028, reducing its immediate outlay to approximately $200 million under pre-feasibility assumptions.
- Project Overview: Copper World is a fully permitted, wholly owned Hudbay project located about 50 km southeast of Tucson, Arizona. It is expected to produce 85,000 tonnes of copper annually during its initial 20-year operational phase, with options to expand further under federal permits.
- Strategic Significance: The $600 million deal is expected to channel $1.5 billion directly into the U.S. critical minerals supply chain—a high priority for policymakers aiming to reduce foreign dependence.
- Market Reaction: Shares in Hudbay surged, reaching their highest levels in over a decade—a clear signal of investor confidence following the announcement.
- Operational Next Steps: A Definitive Feasibility Study (DFS) is under way, targeting completion by mid-2026. Hudbay plans to make a sanctioning decision later that year. Additional benefits include expanded local job opportunities, labor union engagement, tax revenue, and leveraging Mitsubishi’s capital and technical expertise.
Strategic Implications
- Advancing U.S. Mineral Security
The deal aligns closely with U.S. economic and national security goals by bolstering domestic copper output—a crucial metal for green energy, infrastructure, and industrial resilience. - De-Risking Development
Securing a major partner like Mitsubishi provides both financial stability and credibility, reducing project risk and improving prospects for eventual financing and construction. - Unlocking Value in A Competitive Market
Copper World is among the most shovel-ready projects in North America. Mitsubishi’s investment underscores its high internal rate of return potential and Hudbay’s strong execution track record. - Strong Market Signaling
Investor reaction—marked by a double-digit surge in Hudbay’s share price—reveals a positive view of Hudbay’s ability to both develop Copper World and expand its growth pipeline.
