Hudbay Resumes Snow Lake Operations Following Wildfire Evacuation Order

TORONTO, June 16, 2025 (GLOBE NEWSWIRE) -- Hudbay Minerals Inc. (“Hudbay” or the “Company”) (TSX, NYSE: HBM) has resumed operations in Snow Lake following the lifting of evacuation orders in the Snow Lake region on June 14, 2025. The Company continues to collaborate closely with local communities and municipal and provincial authorities to provide support to its employees, their families and neighbours as they navigate their return.

Through the Company’s emergency preparedness and extensive community response efforts, there has been no structural damage to Hudbay’s infrastructure and facilities in Snow Lake and Flin Flon as a result of the wildfires. Hudbay resumed mining activities at the Lalor mine over the weekend with a focus on initially prioritizing the gold zones. Milling activities at the New Britannia gold mill are expected to ramp up to full production this week, while milling activities at the Stall base metal concentrator are expected to ramp up to full production next week as the workforce continues to be impacted by the Flin Flon regional evacuations that are still in place. Given the strong year-to-date performance in Snow Lake, the Company continues to expect to achieve its annual guidance metrics for Manitoba in 2025.

“We remain committed to supporting our Manitoba team and recognize the significant impact this crisis has had on our employees, their families and neighbours, and local First Nations,” said Rob Carter, Hudbay’s Senior Vice President, Canada. “Thank you to the essential personnel who remained behind, our employees who were part of the volunteer firefighting efforts, and all the first responders who have been working tirelessly these last several weeks. We look forward to working with local and provincial authorities on the rebuilding efforts to help our communities move ahead.”

Throughout the wildfire evacuation orders, Hudbay has taken the following actions to support Manitoba and the communities near its operations:

• Doubling its prior commitment to more than $2 million in support funding, including $1.6 million in direct financial support for evacuated Hudbay employees and a $500,000 corporate donation to the Canadian Red Cross to provide critical support to those displaced by wildfires in Manitoba and Saskatchewan.
• Established a Community Relief Donations Fund, where Hudbay will donate $2 for every $1 donated by its employees across the Company, tripling the impact of employee donations.
• Securing accommodations for evacuated employees and their families.
• Deploying external firefighters to aid in emergency response firefighting efforts.
• Executing safeguarding plans to protect Hudbay assets.
• Maintaining communication with the local communities and provincial authorities about the resources Hudbay has available to assist emergency response efforts, such as supplies, equipment and accommodations.
