IMPERIAL REPORTS THE SAFE RETURN OF WORKERS TO SURFACE AT RED CHRIS MINE

Imperial Metals Corp. has provided an update on the fall-of-ground incident that had isolated three workers underground at the 30-per-cent-owned Red Chris mine in northwestern British Columbia. Mine operator Newmont Corp. announced that, at approximately 10:40 p.m. PST, Kevin Coumbs, Darien Maduke and Jesse Chubaty, three Hy-Tech Drilling workers at the Red Chris mine, were safely brought to surface following a fall-of-ground incident.

Newmont stated its relief to share that all three individuals are safe and in good health and spirits. They had consistent access to food, water and ventilation whilst they remained in place in a refuge chamber underground over the past two days. They are now being supported by medical and wellness teams. Their families have been notified.

Imperial is grateful for the safe outcome of the incident and extends its thanks to Newmont and the rescue teams.

Background on rescue effort from the mine operator

At 8:30 p.m. PST on Thursday, July 24, 2025, following around-the-clock efforts, Imperial Metals' specialized line-of-sight scoop successfully cleared the fallen debris from the access tunnel. With the area stabilized, the emergency response team advanced across the impacted zone using equipment with an engineered falling object protective system.

Upon reaching the refuge chamber, the team found Mr. Coumbs, Mr. Maduke and Mr. Chubaty in stable condition. Together with the emergency response team, they returned to surface using the same protected equipment.

This outcome is the result of tireless collaboration, technical expertise, and, above all, safety and care. Imperial Metals extends its heartfelt gratitude to the rescue teams and all those involved, and to Mr. Coumbs, Mr. Maduke and Mr. Chubaty as they recover from this experience.
