value per share
• Copper Mountain is expected to produce 60 ,000 tonnes i of copper by 2027, a greater than 125%
increase over 2024 and a 200% increase from 2024 production levels attributable to Hudbay
• Increases Hudbay's attributable copper production from Canada and reinforces its position as the
second largest copper producer in Canadaii
• Hudbay intends to further invest in Canada's copper and critical minerals sector through the ongoing
optimization program at Copper Mountain and the advancement of the nearby New Ingerbelle
expansion project
• Hudbay gains rights to 15% of the copper concentrate offtake for the next 15 years and 100% thereafter
Toronto, Ontario, March 27, 2025 – Hudbay Minerals Inc. (“Hudbay” or the “ company”) (TSX, NYSE: HBM) is
pleased to announce that it has entered into a n agreement with Mitsubishi Materials Corporation (“MMC”) to acquire
MMC’s 25% interest in Copper Mountain Mine (BC) Ltd. (“CMBC”), the 100% owner of the Copper Mountain mine, for
US$4.5 million in an upfront cash payment and up to US$39.75 million in deferred and contingent cash payments (the

including an intercompany loan owing to Hudbay, of which 25% represents approximately US$104 millioniii.
“This Transaction is aligned with our strategy of growing copper production in mining friendly jurisdictions and further
strengthens Hudbay’s position as a North American copper champion. The Copper Mountain mine is a key asset for
Hudbay and we have been encouraged by the progress of our three-year optimization plan. This Transaction simplifies
the ownership structure of Copper Mountain and provides Hudbay with greater exposure to the mine without adversely
impacting our balance sheet.” said Peter Kukielski, Hudbay’s President and Chief Executive Officer. “Mitsubishi
Materials Corporation has been an outstanding partner, and we look forward to continuing our relationship after the
close of the Transaction.”
The cash consideration of the Transaction consists of:

Continued long-term relationship with MMC:
• Hudbay’s proportion of the copper concentrate offtake from the Copper Mountain mine will increase from 0%
to 15% from the closing date of the Transaction until the 15-year anniversary of such closing date, with MMC

Copper Mountain Mine Overview
The Copper Mountain mine is an open pit copper mine in southern British Columbia, which also produces gold and
silver as by-product metals. Current mineral reserve estimates at Copper Mountain total 346 million tonnes at 0.25%
copper and 0.12 grams per tonne gold with approximately 850 thousand tonnes of contained copper and 1. 3 million
ounces of contained gold. The current mineral reserve estimates support a mine life until 2043, with significant upside
potential for future resource conversion and mine life e xtension beyond 19 years through an additional 125 million
tonnes of measured and indicated resources at 0.21 % copper and 0.10 grams per tonne gold and 372 million tonnes
of inferred resources at 0.25% copper and 0.13 grams per tonne gold, in each case, exclusive of mineral reserves.
Since acquiring Copper Mountain in June 2023, Hudbay has been focused on advancing operational stabilization and
optimization plans, including opening up the mine by re-activating the full mining fleet, adding additional haul trucks,
adding additional mining faces, optimizing the ore feed to the plant and implementing plant improvement initiatives that
mirror Hudbay's successful processes at Constancia. These investments have successfully increased the total tonnes
moved and resulted in stronger mill performance as demonstrated by high mill availability of 92% and copper recoveries
of 82% in 2024, compared to 85% and 80%, respectively, in 2023. In 2025, the planned conversion of the third ball mill
to a second SAG mill is anticipated to result in the ramp-up of mill throughput in the second half of the year . The mill
throughput is anticipated to move towards 50,000 tonnes per day in 2026.
Annual production from Copper Mountain is expected to average approximately 44,000i tonnes of copper and 28,600i
ounces of gold over the next three years. Upon completion of Hudbay’s optimization activities, 2027 copper production
is expected to be 60,000i tonnes, representing a more than 200% increase from attributable production levels in 2024.
