Hudbay Receives Air Quality Permit for Copper World

Hudbay Minerals Inc. ("Hudbay" or the "Company") ( TSX, NYSE: HBM) is pleased to announce that it has received an Air Quality Permit for the Copper World project ("Copper World") from the Arizona Department of Environmental Quality ("ADEQ"). The issuance of this permit is a significant milestone in the advancement of the project as it is the final major permit required for the development and operation of Copper World. Copper World is expected to produce 85,000 tonnes of copper per year over an initial 20-year mine life. All amounts are in U.S. dollars, unless otherwise noted.

"With the receipt of the Air Quality Permit for Copper World, we firmly believe Hudbay now has the best fully permitted copper development project in the Americas," said Peter Kukielski, President and Chief Executive Officer. "We have completed one of the three key prerequisites in our sanctioning plan for Copper World, and we intend to advance feasibility studies and our prudent financial strategy throughout 2025 as we work toward a sanctioning decision in 2026. Copper World is expected to increase Hudbay's consolidated annual copper production by more than 50% from current levels, and the project will be a key contributor to the domestic U.S. supply chain with our plans to produce Made-in-America copper."

Mr. Kukielski added, "Today, Hudbay is the fourth largest copper producer listed on the NYSE and a majority of our institutional shareholders are based in the U.S. We look forward to continuing to grow our presence in the U.S. with our planned $1.7 billion capital investment to build Copper World. Copper World's Made-in-America copper cathode is expected to be sold entirely to domestic U.S. customers and would make Copper World the third largest cathode producer ⁱ in the U.S. We believe Copper World will help meet the growing need for critical minerals in the U.S. related to increased manufacturing capacity, infrastructure development, increased energy independence, domestic battery supply chain needs and strengthening the nation's security."

  Copper World Permitting Completed  

Hudbay has now received all three key state permits required for Copper World development and operation:

•    Mined Land Reclamation Plan –     Completed   – the Mined Land Reclamation Plan was initially approved by the Arizona State Mine Inspector in October 2021 and was subsequently amended and approved to reflect a larger private land project footprint. This approval was challenged in state court, but the challenge was dismissed in May 2023.
 
•    Aquifer Protection Permit –     Completed   – the Aquifer Protection Permit was received on August 29, 2024 from the ADEQ following a robust process that included detailed analysis by the agency and Hudbay, along with a public comment period that was completed in the second quarter of 2024.
 
•    Air Quality Permit –     Completed   – the Air Quality Permit was received on January 2, 2025 from the ADEQ following a similarly robust process, including a public comment period that concluded in the third quarter of 2024.
  
 

Hudbay received the two remaining permits on schedule and the company is pleased with the level of local support received at the public meetings. Hudbay looks forward to providing significant social and environmental benefits for the community and local economy in Arizona. Over the proposed initial 20-year mine life, the company expects to contribute more than $850 million in U.S. taxes, including approximately $170 million in taxes to the state of Arizona. Hudbay also expects Copper World to create more than 400 direct jobs and up to 3,000 indirect jobs in Arizona. Copper World will offer competitive wages and benefits, and the company intends to engage in partnerships with local apprenticeship readiness programs and community-based workforce training programs across the skilled and technical levels to fill and maintain all positions. The company has received support from several local unions, with the signing of a letter of intent for the project execution phase in May 2024, including The International Brotherhood of Boilermakers, Iron Ship Builders, Forgers and Helpers Local 627, The Laborers International Union of North America Local 1184, and The United Brotherhood of Carpenters and Joiners of America Local 1912.

  Advancing Prudent Financing Plan with Disciplined Capital Allocation  

As part of Hudbay's disciplined financial planning approach to Copper World, in October 2022, the company introduced a three prerequisites plan ("3-P"), as shown in Figure 1, including specific leverage targets and other criteria that would need to be achieved prior to making a project sanctioning decision for Copper World. The 3-P plan has the following components:

1.    Permits   –   Completed   – receipt of all required state level permits.
 
2.    Plan   –   On Track   – completion of a definitive feasibility study ("DFS") with an internal rate of return of greater than 15%. Hudbay commenced activities related to the feasibility study for Copper World in late 2024 and expects to advance definitive feasibility study activities throughout 2025 with completion of the study in the first half of 2026.
 
3.    Prudent Financing Strategy   –   On Track   – multi-faceted financing strategy, including a committed minority joint venture partner, a renegotiated precious metals stream agreement optimized for the current project, a net debt to EBITDA ratio of less than 1.2 times, a minimum cash balance of $600 million, and limited non-recourse project level debt.
   
 

Since the release of the 3-P plan, Hudbay has taken prudent measures to transform its balance sheet in preparation for a sanctioning decision, through strong cash flow generation, deleveraging initiatives and the completion of a successful equity offering. Hudbay has generated $840 million in adjusted EBITDA ⁱⁱ and substantially reduced net debt ⁱⁱ by $506 million for the twelve months ending September 30, 2024. The net debt reduction, together with higher levels of adjusted EBITDA ⁱⁱ , have improved the company's net debt to adjusted EBITDA ratio ⁱⁱ to 0.7x. This improved balance sheet flexibility and accelerated debt reduction significantly advances the company's progress towards its prudent financing strategy as part of its 3-P plan and has resulted in the achievement of the targeted 1.2x net debt to 12-month trailing adjusted EBITDA ratio well ahead of schedule.

Now that the major permits for Copper World have been received, Hudbay intends to commence a minority joint venture partner process early in 2025. It is anticipated that any minority joint venture partner would participate in the funding of definitive feasibility study activities in 2025 as well as in the final project design and construction for Copper World.

The opportunity to sanction Copper World is not expected until 2026 based on current estimated timelines.

  About Copper World  

The 100% owned Copper World project is located in Pima County, Arizona, approximately 50 kilometres southeast of Tucson. Copper World includes seven deposits discovered in 2021, together with the East deposit (formerly known as the Rosemont deposit). A new resource model was completed for the preliminary economic assessment ("PEA") of Copper World in 2022, which contemplated a two-phased mine plan with Phase I as a standalone operation requiring state and local permits only and Phase II expanding onto federal lands requiring federal permits.

In September 2023, Hudbay released its enhanced pre-feasibility study ("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 $1.47 and $1.81 per pound of copper ^{i i i} , respectively. A variable cut-off grade strategy allows for higher mill head grades in the first ten years, which increases annual production to approximately 92,000 tonnes of copper at average cash costs and sustaining cash costs of $1.53 and $1.95 per pound of copper ⁱⁱⁱ , respectively.

Based on the PFS, the estimated initial capital investment for Phase I of Copper World is approximately $1.3 billion with an additional $0.4 billion in year four for the construction of a concentrate leach facility. At a copper price of $3.75 per pound, the after-tax net present value ("NPV") of Phase I using an 8% discount rate is $1.1 billion and the internal rate of return ("IRR") is 19%.

Copper World is one of the highest-grade open pit copper projects in the Americas ^iv with proven and probable mineral reserves of 385 million tonnes at 0.54% copper. There remains approximately 60% of the total copper contained in measured and indicated mineral resources (exclusive of mineral reserves), providing significant potential for Phase II expansion and mine life extension. In addition, the inferred mineral resource estimates are at a comparable copper grade and provide significant upside potential.
