Hudbay’s US properties are the Copper World Project, located in Arizona, and the Mason project, located in Nevada.

The Copper World deposits were discovered in 2021 and are located predominately on our wholly owned patented mining claims adjacent to our East deposit. The discovery drill program was initiated in 2020 to confirm historic drilling and after receiving encouraging results, we launched a larger drill program in 2021 which results in an initial mineral resource estimate.

Hudbay has been acquiring additional private land in the area to support an operation entirely on private land. The company now holds approximately 5,500 acres of private land and patented mining claims, which is enough to support the first 20 years of production at the Copper World Project.

Following the recent exploration success on patented mining claims and ongoing litigation uncertainty regarding the project design set forth in the 2017 feasibility study for the East deposit, Hudbay began to evaluate alternative design options to unlock value within this prospective district in Arizona. This led to the release of a robust preliminary economic study for the Copper World Complex in June 2022. The study contemplates a two-phased mine plan with the first phase reflecting a standalone operation with processing infrastructure on Hudbay’s private land and mining occurring on patented mining claims with a defined two-phased mine plan. This strategy was designed to split Phase I requiring only state and local permits to advance the project and separate out the federal land permitting requirements needed for expansion in Phase II. In September 2023, Hudbay released the enhanced Pre-Feasibility Study outlining the company's intentions for Phase 1, to develop a standalone open-pit operation requiring only state and local permits for an extended 20-year mine life.

Copper World is a fully permitted project advancing into the final feasibility and planning phase to progress towards the development of the mine in the coming years. In 2021, the State Mine Inspector approved Copper World’s Mined Land Reclamation Plan (MLRP), and more recently, in 2024 the Arizona Department of Environmental Quality (ADEQ) approved both the Aquifer Protection Permit and the Air Quality Permit. These milestones underscore Copper World’s dedication to responsible development. Mining in the United States is highly regulated, and the rigorous review process conducted by Arizona’s state agencies confirms that Copper World’s operations will meet stringent environmental and operational standards.

The Mason deposit, acquired in late 2018, is one of the largest undeveloped copper resources in the Americas. It is similar in scale to Constancia and Hudbay released a robust preliminary economic study on Mason in April 2021.

Fact

The Copper World Project will support U.S. copper supply through onsite production of copper cathode expected to be sold entirely to domestic customers and reduce energy consumption, GHG and sulfur emissions associated with overseas shipping and processing.

Green Economy

From solar panels to electric vehicles—copper is a key element in de-carbonization efforts and the shift to renewable energy sources. Hudbay will support America's transition to a cleaner future, by providing the copper we need to build the innovative products and technologies that will power our new sustainable future.

The Copper World Complex has been designed to meet the growing copper demand in the U.S. through the onsite production of “Made in America” copper cathode which is expected to be sold entirely to domestic U.S. customers.

Environment

Producing copper cathode on-site reduces the operation’s total energy requirements, and greenhouse gas (“GHG”) and sulfur (SO2) emissions by eliminating overseas shipping, smelting and refining activities associated with a typical copper concentrate operation. It is estimated that Copper World will reduce total energy consumption by more than 10% when compared to a project that produces copper concentrates for overseas smelting and refining.

There are several other emission reduction potential opportunities that Hudbay is considering, including to source renewable energy from local providers, the use of autonomous or electric haul trucks at the operation and various post-reclamation land uses such as domestic renewable energy production.

People

As one of the largest copper development projects in the U.S., Copper World will create thousands of high-quality jobs, boost local businesses, and generate substantial tax revenue to support community services and infrastructure. This project represents a long-term investment in Arizona’s economy, driving growth and innovation while providing a stable, domestic supply of copper critical to industries across the nation.

At Copper World, we believe strong communities, quality education, a healthy environment, and a thriving local economy are essential. Our Community Giving and Investment program focuses on supporting the priorities that matter most to our neighbors. We invest in areas where there are pressing needs, and where our contributions can make a meaningful and lasting impact. We are proud to have supported organizations such as the Children’s Advocacy Center, the Santa Cruz County Fair and Rodeo Association, the Tucson Metro Chamber of Commerce, the University of Arizona School of Mining and Mineral Resources, and the Vail School District Foundation.
