Hudbay Provides an Update on the Wildfire Situation near Flin Flon

TORONTO, May 29, 2025 (GLOBE NEWSWIRE) -- Hudbay Minerals Inc. (“Hudbay” or the “Company”) (TSX, NYSE: HBM) is responding to the evolving wildfire situation in northern Manitoba and is working closely with local authorities to ensure its employees remain safe as well as comply with the regional wildfire evacuation order that includes Flin Flon and the surrounding areas. Only essential Hudbay personnel, authorized by emergency services, will remain in Flin Flon to assist with emergency activities. While Hudbay no longer has active mine production activities in Flin Flon after the closure of the 777 mine in 2022, the Company has ongoing care and maintenance activities in Flin Flon as well as services to support the Snow Lake operations, including concentrate handling, fabrication shops and administration. The Flin Flon community has been an important part of Hudbay’s operations for nearly 100 years.

Hudbay continues to maintain operations in Snow Lake, which is located approximately 200 kilometres east of Flin Flon. The Company expects temporary reduced production levels in Snow Lake as a large portion of its workforce resides in Flin Flon. However, given the strong performance in Snow Lake year-to-date, the Company remains well-positioned to achieve its annual guidance metrics for 2025. Hudbay has paused exploration activities in the Flin Flon and Snow Lake region as fire mitigation efforts are underway.

“The safety of our employees, their families and the communities we serve is our top priority,” said Rob Carter, Vice President of Hudbay’s Manitoba Business Unit. “We are collaborating closely with the City of Flin Flon, local communities and provincial authorities to provide support during this challenging time. We will continue to monitor the situation, ensuring a safe return to full operations as soon as it is advisable.”

As part of its commitment to support Manitoba and the Flin Flon community, Hudbay is taking the following actions:

• Securing additional accommodations in Snow Lake for its evacuated employees and their families.
• Deploying trained emergency personnel to aid firefighting efforts.
• Maintaining communication with the City of Flin Flon, local communities and provincial authorities about the resources Hudbay has available to support emergency response efforts, such as supplies, equipment and water trucks.
• Providing facility infrastructure information to assist with planning and response.
