Imperial Reports Fall of Ground Incident at Red Chris Mine

Vancouver | July 23, 2025 | Imperial Metals Corporation (“Imperial” or the “Company”) (TSX:III) reports that on

July 22, two fall of ground incidents occurred in the access way to an underground work area of a non-producing

project at the Red Chris Mine in British Columbia, Canada. Imperial holds a 30% interest in the Red Chris copper-

gold mine.

At the time of the initial incident, three contractor employees were working more than 500 metres beyond the

affected zone and were asked to relocate to a designated refuge station before a subsequent fall of ground blocked

the access way. Following the first event, contact was established with the individuals and confirmation was received

that they had safely relocated to one of multiple self-contained refuge bays. The refuge stations are equipped with

adequate food, water and ventilation to support an extended stay.

The second fall of ground event subsequently restricted communication. To ensure focus on the response efforts, a

standdown of operations at Red Chris has been implemented. With the support of industry, specialist teams from

nearby mine sites are being assembled to respond to the situation.

All appropriate emergency response protocols were activated immediately. Newmont, the mine operator, is actively

assessing all methods and technologies available to restore communication and safely bring the workers to surface.

The priority remains on ensuring the safety of the three individuals and of the emergency response teams supporting

this effort.

Further updates will be provided as more information becomes available.
