Hudbay to Acquire Arizona Sonoran Creating the Third Largest Copper District in North America
Hudbay Minerals consolidates Arizona copper district with $1.48 billion acquisition of Arizona Sonoran.

On March 2, 2026, Hudbay Minerals Inc. announced a definitive agreement to acquire all outstanding shares of Arizona Sonoran Copper Company (ASCU). The transaction is valued at approximately $1.48 billion. ASCU shareholders will receive 0.242 of a Hudbay common share for each ASCU share held. This represents a 30% premium to the closing price on February 27, 2026. The deal effectively merges ASCU’s flagship Cactus Project with Hudbay’s existing Arizona assets (Copper World), aiming to create the third-largest copper district in North America.
- Materiality: This is a "Game Changer" as it represents the total exit and crystallization of value for ASCU shareholders.
- Strategic Fit: The acquisition follows a series of strategic moves by ASCU, including the termination of the Nuton (Rio Tinto) joint venture in February 2026, which cleared the path for a clean takeover.
- Production Profile: The combined entity targets over 250,000 tonnes of copper per year by 2030, with the Cactus project contributing 92,000 tonnes.
- Financial Accretion: The deal is expected to be accretive to Hudbay’s net asset value and reserves per share, while providing ASCU shareholders with immediate liquidity and exposure to a diversified producer.
ASCU’s flagship is the 100%-owned Cactus Project in Pinal County, Arizona. It is a brownfield project on private land, significantly de-risking the permitting process. - PFS Results (Nov 2025): After-tax NPV8% of US$2.3 Billion, IRR of 22.8%. - Reserves: 5.3 billion pounds of contained copper. - Mine Life: 22 years.
