Arizona Sonoran Copper Company

What Arizona Sonoran Copper Company does

Arizona Sonoran Copper Company Inc. is a pre-production copper developer focused on the 100%-owned Cactus Mine Project, a brownfield open-pit heap leach and Solvent Extraction / Electrowinning (SX/EW) operation on the former ASARCO Sacaton mine site in Pinal County, Arizona, with the contiguous Parks/Salyer deposit feeding the same processing circuit. The company was incorporated in 2019 in British Columbia (originally as Elim Mining), listed on the TSX (ASCU) and OTCQX (ASCUF) in 2021, and operates from a Toronto headquarters with a Casa Grande, Arizona project office; it has 11-50 employees. The October 2025 Pre-Feasibility Study outlines a 22-year mine producing an average of 113,000 short tons per year of LME Grade A copper cathode over the first 10 years, with first cathodes targeted for H2 2029, initial capex of US$977M, C1 cash cost of $1.34/lb, AISC of $1.62/lb, after-tax NPV8 of US$2.3 billion and IRR of 22.8% at $4.25/lb Cu, supported by 5.3 billion pounds of contained copper in mineral reserves across a consolidated 7,843-acre land package.

Arizona Sonoran generates no operating revenue; during pre-production it raises capital via bought-deal equity offerings and strategic private placements (including C$19.9M from Hudbay in January 2025, a C$45M Scotiabank offering in June 2025, and a C$86.3M Canaccord-led bought deal in December 2025), with future revenue to be derived from on-site production and sale of LME Grade A copper cathode directly into the U.S. domestic refined copper supply chain. The company's go-to-market combines event-driven capital-markets execution (underwritten by Canaccord Genuity, Raymond James, Scotiabank, and Paradigm Capital) with enterprise relationship development toward tier-1 lenders, export-credit agencies, and strategic acquirers (Hannam & Partners was engaged in June 2025 to arrange project debt). The customer segments addressed by the future product are U.S. downstream copper consumers facing structural supply gaps driven by electrification, EV, AI data-center, and grid demand, and the company maintains a community-engagement program with the Pinal County host community and ASARCO reclamation stewardship.

On March 2, 2026 Arizona Sonoran entered a definitive arrangement to be acquired by Hudbay Minerals in an all-share transaction at 0.242 Hudbay shares per ASCU share (a 30% premium, US$1.48 billion equity value), securityholders approved the deal on May 11, 2026 with over 99% of votes in favor, and Hudbay completed the acquisition on June 24, 2026, making Arizona Sonoran a wholly-owned subsidiary of Hudbay and delisting ASCU from the TSX. The combination is positioned by Hudbay as the third largest copper district in North America, with a stated production growth pathway from ~125,000 tonnes to >250,000 tonnes by 2030 and >350,000 tonnes once Cactus reaches full production.

Core offering

Arizona Sonoran Copper Company is a pre-production copper developer advancing its 100%-owned Cactus Mine Project in Pinal County, Arizona. The flagship project is a brownfield open-pit copper operation (former ASARCO Sacaton mine site) planning to produce LME Grade A copper cathodes via conventional two-stage crushing, heap leach pad processing, and Solvent Extraction/Electrowinning (SX/EW). The October 2025 Pre-Feasibility Study outlines a 22-year operation producing an average of 113,000 short tons of copper cathode per year over the first 10 years, with first cathodes targeted for H2 2029. The company was acquired by Hudbay Minerals on June 24, 2026.

Product overview

Arizona Sonoran Copper Company is a single-asset-focused copper exploration and development company built around one core development project — the Cactus Mine Project — augmented by the contiguous Parks/Salyer Deposit. The portfolio is structured as a flagship project (Cactus) plus an immediately adjacent brownfield deposit (Parks/Salyer) that together support a 22-year open-pit heap leach-SXEW cathode operation, rather than a multi-product software or SaaS platform. The company’s offering is therefore a unified mining project, with Parks/Salyer functioning as a sub-project feeding the Cactus processing circuit, and the Parks/Salyer Feasibility Study drilling program serving as the active resource-definition workstream.

Direct peers

• Hudbay Minerals Inc. Hudbay acquired Arizona Sonoran in June 2026 and is the parent company of ASCU's Cactus Project. Hudbay's Copper World project in Arizona is the most directly comparable peer asset: same jurisdiction (Arizona), same copper-cathode SXEW product, and now part of the same combined copper hub, making Hudbay the single closest operating peer.
• Capstone Copper Corp. Capstone Copper is a mid-tier copper producer with Arizona assets (Pinto Valley, currently studying an expansion to SXEW cathode) and Mexican/Chilean operations. Capstone is highly comparable as a North America-focused copper producer pursuing SXEW cathode growth, with project economics, capital intensity, and permitting approaches directly relevant to Cactus.
• Taseko Mines Limited: Taseko's Florence Copper project in Arizona is an in-situ copper recovery (ISR) operation producing LME Grade A copper cathode in Pinal County — the same county as Cactus. Florence is a direct functional peer: same U.S. jurisdiction, same cathode product, similar heap-leach/SXEW copper recovery pathway, and a directly relevant benchmark for permitting, capital intensity, and U.S. domestic cathode economics.
• Lundin Mining Corporation: Lundin Mining is a mid-tier diversified base metals producer with copper assets including Caserones (Chile) and Neves-Corvo (Portugal). Comparable as a copper-focused mid-tier with development pipelines and SXEW exposure, and a useful peer for capital intensity, AISC benchmarks, and project financing structures relevant to Cactus.
• KGHM Polska Miedź S.A. KGHM is a major integrated copper and silver producer with significant SXEW cathode operations in Poland and overseas assets including the Sierra Gorda copper-molybdenum mine in Chile. KGHM is comparable as a copper producer leveraging SXEW cathode production at scale, with project economics and operating-cost benchmarks relevant to Cactus.

Broad incumbents

• Freeport-McMoRan Inc. Freeport-McMoRan is the largest U.S. copper producer, operating large-scale Arizona open-pit copper mines (Morenci, Bagdad, Safford, Sierrita) that produce copper cathode via SXEW alongside concentrate. Cactus is positioned as a future mid-tier Arizona producer directly into the same U.S. domestic copper market served by Freeport's Arizona operations.
• Southern Copper Corporation: Southern Copper is one of the world's largest integrated copper producers with open-pit mining and SXEW operations across Peru and Mexico. While not a direct U.S. competitor, Southern Copper is a relevant benchmark for open-pit heap-leach SXEW operating costs, copper cathode unit economics, and long-life reserve strategy.
• First Quantum Minerals Ltd. First Quantum is a global copper producer with Cobre Panamá, Sentinel, and Kansanshi operations. While primarily operating outside the U.S., First Quantum is comparable as a copper-focused miner pursuing SXEW cathode production, expansion projects, and project debt financings — a useful peer for large-scale capex, project execution risk, and copper price sensitivity.
• Rio Tinto Group: Rio Tinto's Nuton venture was an active JV partner with ASCU on the Cactus Project (terminated February 2026) and Rio Tinto operates Resolution Copper in Arizona and Kennecott in Utah. Rio Tinto is comparable as a major copper miner with active U.S. growth projects, bio-heap leaching technology, and tier-one capex/project finance capabilities relevant to Cactus.

Emerging players

• Imperial Metals Corporation: Imperial Metals owns the Mount Polley copper-gold mine in British Columbia and is pursuing the Red Chris copper-gold project in partnership with Newcrest/Newmont. Comparable as a smaller, North-America-focused emerging copper producer navigating similar project-finance, permitting, and development-execution dynamics relevant to ASCU's pre-production profile.
