Hudbay Minerals Inc. (“Hudbay” or the “company”) (TSX, NYSE: HBM) today announced that it has filed a National Instrument 43-101 technical report containing the results of the preliminary economic assessment of its 100%-owned Copper World Complex in Arizona, which includes the recently discovered Copper World deposits along with the Rosemont deposit. The results were previously released in Hudbay’s news release dated June 8, 2022 and are highlighted below. All dollar amounts are in US dollars, unless otherwise noted.
  • Two-phase mine plan has an after-tax net present value (10%) of $1,296 million and generates an 18% internal rate of return at $3.50 per pound copperi
  • The processing facilities are planned to have annual production capacity of 100,000 tonnes of copper cathode during Phase I and 125,000 tonnes of copper cathode during Phase II, and have been designed to reduce the project's carbon footprint to produce "Made in America" copper
  • Supports U.S. copper supply through onshore production of copper cathode expected to be sold entirely to domestic customers and eliminates GHG and sulfur emissions associated with overseas shipping and processing
  • Phase I reflects a standalone operation on private land and patented mining claims over a 16-year mine life with average annual copper production of approximately 86,000 tonnesii at cash costs and sustaining cash costs of $1.15 and $1.44 per pound of copperiii, respectively, generating an after-tax net present value (10%) of $741 million and an internal rate of return of 17%i
  • Phase I of the Copper World Complex includes a 60,000 ton per day sulfide concentrator, a 20,000 ton per day oxide heap leach, an SX/EW facility and a concentrate leach facility with an initial capital cost estimate of approximately $1.9 billion. The concentrator is intended to expand to 90,000 tons per day in Phase II
  • Phase II expands mining activities onto federal land and extends the mine life to 44 years with average annual copper production of approximately 101,000 tonnesii at cash costs and sustaining cash costs of $1.11 and $1.42 per pound of copperiii, respectively. Phase II provides additional optionality with an after-tax net present value (10%) of $555 million and an internal rate of return of 49% (and a projected after-tax net present value (10%) of $2,806 million at the time of Phase II sanctioning)i
  • Significant increase in copper contained in all mineral resource categories
  • Hudbay is evaluating several opportunities to optimize the project, including potential processing and initial capital optimizations, the potential to expand Phase I beyond 16 years with additions to the company's private land package for tailings and waste rock storage and the potential to accelerate Phase II if federal permits are received earlier than as outlined in the PEA

For additional details on the Copper World Complex, please refer to the technical report titled “NI 43-101 Technical Report, Copper World Complex, Pima County, Arizona USA”, effective May 1, 2022, which was filed today under Hudbay’s profile on SEDAR at www.sedar.com and will be filed on EDGAR at www.sec.gov.

Non-IFRS Financial Performance Measures

Cash cost and sustaining cash cost per pound of copper produced are shown because the company believes they help investors and management assess the performance of its operations, including the margin generated by the operations and the company. These measures do not have a meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS and are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. Other companies may calculate these measures differently. For further details on these measures, please refer to page 39 of Hudbay’s management’s discussion and analysis for the three months ended March 31, 2022 available on SEDAR at www.sedar.com.

Qualified Person and NI 43-101

Mr. Tavchandjian is a qualified person pursuant to Canadian Securities Administrators’ National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”).

Mineral resources that are not mineral reserves do not have demonstrated economic viability. This preliminary economic assessment (“PEA”) is preliminary in nature, includes inferred resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty the preliminary economic assessment will be realized.

i The valuation metrics presented in this news release are based on a preliminary economic assessment that includes an economic analysis of the potential viability of mineral resources. Mineral resources that are not mineral reserves do not have demonstrated economic viability. This preliminary economic assessment is preliminary in nature, includes inferred resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty the preliminary economic assessment will be realized. See “Qualified Person and NI 43-101” below.ii "Tonnes” refers to metric tonnes and “tons” refers to imperial or U.S. short tons. The mine plan assumes external concentrate is sourced in years when spare capacity exists at the SX/EW facility in order to maximize the full utilization of the facility. Copper cathode production from mined resources excludes the production from external concentrate. Average annual copper cathode production from external concentrates is approximately 12,000 tonnes in Phase I and 22,000 tonnes in Phase II. There remains the potential to replace external copper concentrate with additional internal feed.iii Cash cost and sustaining cash cost, net of by-product credits, per pound of copper produced from internally sourced feed and excludes the cost of purchasing external copper concentrate, which may vary in price or potentially be replaced by additional internal feed. By-product credits calculated using the following commodity prices: molybdenum price of $11.00 per pound, silver stream price of $3.90 per ounce and amortization of deferred revenue as per the company’s approach in its quarterly financial reporting. By-product credits also include the revenue from the sale of excess acid produced at a price of $145 per tonne. Sustaining cash cost includes sustaining capital expenditures and royalties. Cash cost and sustaining cash cost are non-IFRS financial performance measures with no standardized definition under IFRS.
