Hudbay Celebrates Major Milestone with Millionth Ounce of Gold Recovered from Lalor Mine

TORONTO, Jan. 16, 2025 (GLOBE NEWSWIRE) -- Hudbay Minerals Inc. (“Hudbay” or the “Company”) (TSX, NYSE: HBM) is pleased to announce that it has surpassed a total of one million ounces of gold produced at its Lalor Mine in Snow Lake, Manitoba. This milestone reinforces the significant value Hudbay has unlocked by combining its exploration expertise, processing infrastructure and operating efficiency to maximize gold production at its Snow Lake operations.

“We are so pleased with the dedication and hard work of the Manitoba operating team that has led to this outstanding achievement,” said Peter Kukielski, President and Chief Executive Officer. “This milestone underscores Lalor’s robust performance and is the result of strategic investments, continuous operational improvements and exploration success, along with the team’s focus on building a long-term sustainable business. Hudbay’s long standing history in Manitoba and significant future exploration initiatives will continue to drive prosperity in the region and generate significant future cash flows for the business.”

“Reaching one million ounces of gold recovered from Lalor is a momentous achievement,” said Rob Carter, Vice President, Manitoba Business Unit. “This milestone reflects the dedication, hard work, and innovative spirit of our entire team, and I am incredibly proud of their accomplishments. This achievement sets the stage for continued success, demonstrating the enduring value of the Lalor deposit and propelling us towards continued growth and success through innovative and efficient mining and milling solutions."

Key Snow Lake gold highlights:

• 2007 – Hudbay discovered the Lalor deposit with the intersection of a zinc-rich base metal zone.
• 2009 – Hudbay discovered new gold and copper-gold zones down plunge at Lalor and released a conceptual gold resource estimate.
• 2010 – Construction of the Lalor mine commenced.
• 2014 – Lalor achieved commercial production, initially from the upper base metal ore zones, while significant gold resources remained undeveloped at depth.
• 2015 – Hudbay acquired the New Britannia gold mill in Snow Lake to provide a potential gold processing solution that would augment existing base metal processing at the Stall mill.
• 2016 to 2018 – Completed additional work on the Lalor gold zones to confirm and upgrade mineral resource estimates.
• 2019 – Began executing a multi-phased gold strategy in Snow Lake focused on increased annual gold production from optimization initiatives, including the decision to refurbish New Britannia to increase processing capacity and achieve higher recoveries for Lalor’s gold ore.
• 2021 – Successful start-up of the New Britannia mill in late 2021.
• 2022 – First full year of operations at New Britannia delivered an approximate 90% increase in annual gold production from Snow Lake to 146,449 ounces in 2022, compared to 77,376 ounces in 2020.
• 2023 – The New Britannia mill achieved record throughput levels averaging 1,650 tonnes per day, exceeding its design capacity of 1,500 tonnes per day, which contributed to record annual gold production of 187,363 ounces in 2023.
• 2024 – New Britannia continued to achieve new record throughput levels above the budgeted 1,800 tonnes per day, which contributed to the Snow Lake operations achieving record quarterly gold production in the third quarter of 2024. As disclosed in the company’s third quarter 2024 results, Hudbay expects gold production in Manitoba to exceed the top end of the 2024 gold production guidance range of 200,000 ounces.
• December 2024 – The Snow Lake operations achieved historic milestone of one million ounces of gold recovered from ore at the Lalor mine.

With approximately two million ounces of contained gold in current mineral reserve estimates and another 1.4 million ounces of contained gold in inferred mineral resources, Hudbay expects to continue to unlock significant value in Snow Lake and looks forward to further growing the mineral resource base through regional exploration as the company continues to execute one of the largest exploration programs in its history in Snow Lake.
