Hudbay Provides an Update on Snow Lake Operations due to Wildfire Evacuation Order

TORONTO, July 10, 2025 (GLOBE NEWSWIRE) -- Hudbay Minerals Inc. ("Hudbay" or the "Company") (TSX, (TSX, NYSE:HBM) continues to respond to the wildfire situation in northern Manitoba and is working closely with local and provincial authorities to ensure its employees remain safe as well as comply with the mandatory wildfire evacuation order effective today for the town of Snow Lake. As a result, the Company has enabled a controlled, safe and orderly temporary suspension of operations in Snow Lake.

Through the Company's emergency preparedness procedures, all assets have been secured, and a limited workforce remains at site to conduct ongoing monitoring programs and assist with emergency activities. Hudbay believes its infrastructure and facilities in Snow Lake are well-protected from the wildfires and have a low risk of being damaged. Activities in Flin Flon continue unaffected given the current wildfires are not located near the city of Flin Flon. Some exploration activities near Snow Lake have been paused.

"We remain committed to ensuring the safety of our employees, their families, local First Nations members and the communities we serve. With the current unprecedented dry conditions in northern Manitoba, our team continues to manage through the intermittent wildfire situation, and we are proud of the proactive actions taken to minimize impact to our people and our facilities," said Rob Carter, Hudbay's Senior Vice President, Canada. "We expect a quick and safe return to full operations as soon as possible, and we will continue to work with local and provincial authorities to ensure continued rebuilding of our communities after this difficult wildfire season."

Hudbay expects operations to resume efficiently once the wildfire situation improves, given the effectiveness of the Company's emergency preparedness procedures and the insights gained from previous wildfire experiences. The Company continues to expect to achieve its annual guidance metrics for Manitoba in 2025 despite the temporary wildfire impacts.
