Red Chris Exploration and Mount Polley Update

Vancouver | December 8, 2021 | Imperial Metals Corporation (the “Company”) (TSX:III) reports further drilling results

continue to expand the mineralization at the East Ridge zone at the Red Chris mine. Hole RC739 returned 390 metres at

0.48% copper and 0.63 g/t gold from 1,088 metres, including 44 metres at 1.3% copper and 2.0 g/t gold from 1,402 metres.

This hole is located 100 metres east of RC727 (previously reported). Hole RC745 located a further 100 metres east of RC739,

returned 366 metres of 0.57% copper and 0.45 g/t gold from 728 metres, including 36 metres at 1.2% copper and 1.4 g/t

gold from 960 metres. The mineralization at East Ridge is open to the east and at depth with ongoing drilling to define the

extents.

Brian Kynoch, President of Imperial Metals, said, “The East Ridge zone is well located, as the exploration ramp being driven

to access the top of the deep East Zone is about 200 met res to the north of the East Ridge zone and could provide access

for both underground drilling and potentially underground development. Drilling continues to expand the zone, with

drillhole RC739 located 100 met res east of RC727 returning 390 metres grading 0.48% copper and 0.63 g/t gold, including

a 44 metre interval grading 1.3% copper and 2.0 g/t gold.”

The East Ridge zone, located in the porphyry corridor about 300 metres along strike east of the East Zone, is outside of the

current Mineral Resource estimate . The drilling has confirmed continuity of the East Ridge zone mineralization (>0.4%

copper and >0.4 g/t gold) over dimensions of 600 metre high, 500 metre long and 125 metre wide, and with the higher

grade (>0.8% copper and >0.8 g/t gold) over 500 metre high, 300 metre long and 100 metre wide. The mineralization

remains open to the east and at depth. Drilling is ongoing with 18 holes completed and four in progress. The follow up

drilling is being completed with angle holes on a nominal 100 metre by 100 metre grid.

The Company has taken initial steps towards recommencement of operations at Mount Polley mine. Stripping operations

began in November and about 344,000 tonnes of material were mined during the month. This work is being undertaken to

complete the stripping required to enable milling operations to restart in 2022. Mechanical and electrical contractors

continue to work on refurbishing the plant, including work on tailings slurry and reclaim water pipeline s and pumps,

crushers, conveyors, screens, grinding mills and plant water systems. In early December, the crushing plant was

commissioned and a trial of the crushing plant was successfully completed providing crush material for winter road

maintenance. The Mount Polley management team is targeting the plant to be ready for a Spring 2022 restart of plant

operations.

blanks, standards and duplicates was completed for all diamond drilling samples submitted to the labs. Significant assay

intervals reported represent apparent widths. Insufficient geol ogical information is available to confirm the geological

model and true width of significant assay intervals.
