Imperial Provides Production and Red Chris Exploration Update

Vancouver | October 26, 2022 | Imperial Metals Corporation (the “Company”) (TSX:III) reports Red Chris metal production

(100%) for the third quarter of 2022 was 19.2 million pounds copper and 17,51 3 ounces gold, down 1 3% and 10%

respectively from the 22.0 million pounds copper and 19,540 ounces gold produced during the second quarter of 2022.

Gold production of 17,513 ounces was lower than the prior period due to lower recovery and lower throughput. Recovery

is expected to improve in the December 2022 quarter with various improvement initiatives nearing completion including

the cleaner column expansion project. Gold head grade was consistent with the prior period. Copper production was down

13% on lower throughput and grade. Mined grades for copper and gold are expected to decrease with mining now complete

in Phase 5.

Imperial’s 30% portion of the second quarter production was 5.75 million pounds copper and 5,254 ounces gold.

Production at Mount Polley was 2.4 million pounds copper and 5,08 4 ounces gold for the third quarter . During the third

quarter 984,814 tonnes were milled. There has been a steady increase in throughput from 7,268 tonnes per day in July to

11,079 tonnes per day in August to 13,868 tonnes per day in September. Further increases in throughput were hampered

by the trunnion machining that was required to repair Pebble Mill 3. This work is complete and Pebble Mill 3 was put into

operation in early October. All eight mills in the grinding circuit are now operational, and we look forward to increasing the

mill throughput.

Red Chris Exploration Update

During the quarter, there were up to seven diamond drill rigs in operation. A further 20,926 metres of drilling has been

completed from 27 drill holes, with all drill holes intersecting mineralization. Approximately 50,000 metres of drilling is

planned for the second half of 2022 from eight drill rigs . Two of the rigs are drilling from underground stations along the

exploration decline. Drilling from underground will reduce the meterage required to further test the East Ridge and the

surface disturbance required to construct drill pads and roads.

East Ridge drilling is ongoing with 63 holes completed and six in progress. Drilling to date has tested a corridor 900 metres

long and to a vertical extent of 1,000 metres within which zones of higher-grade mineralization have been identified. Drilling

is being completed on a nominal 100 metres x 100 metres grid to determine the extent and continuity of the East Ridge

zone and further define the higher-grade mineralization in the East Ridge zone. The East Ridge zone is not included in the

current Mineral Resource estimate.

Drilling continues to expand the vertical extent of the East Ridge mineralization. The latest drilling results from holes RC819,

RC820 and RC835 extend the higher-grade mineralization by a further 100 metres at depth to more than 600 metres vertical.

The zone remains open to depth on these sections.

RC819 was drilled on section 37N and was drilled to test the down -dip extension of the East Ridge zone. RC819 returned

334 metres of 0.50% copper and 0.35 g/t gold from 1,276 metres, including 56 metres of 0.80% copper and 0.83 g/t gold

(see Figure 32, cross section 37N).

RC820 was drilled on section 36 N to test the down -dip extension of mineralization encountered in RC750W (previously

released). RC820 returned 312 metres of 0.49% copper and 0.49 g/t gold from 1 ,296 metres and 278 meters of 0.44%

copper and 0.74 g/t gold from 1 ,658 metres; these intervals are separated by 50 meters of late-staged barren porphyry

(Phase 3 porphyry). Both intervals included higher-grade intervals; the upper interval included 16 meters from 1,562 meters

of 1.2% copper and 1.7 g/t gold, and the lower interval included 22 metr es from 1,882 metres of 1.8% copper and 3.3 g/t

gold (see Figure 31, cross section 36N).

RC835, which was drilled on section 34N, returned 284 metres of 0.63% copper and 0.75 g/t gold from 1 ,295 metres

including 86 metres from 1,459 metres of 1.2% copper and 1.7 g/t gold. It is the furthest hole down dip on section 34N and

extends the zone at depth (see Figure 29, cross section 34N).

Drilling within the East Ridge continues to confirm the continuity of the zone. As an example, in RC808, on section 38N and

located 100 metres above RC786 (previously reported), intercepted 222 metres of 0.61% copper and 0.44 g/t gold from 818

metres, including a higher-grade intercept of 28 metres of 1.6% copper and 1.5 g/t gold from 936 metres (see Figure 33,

cross section 38N).

Drilling completed between the Main Zone pit and the Gully zone included RC813, located approximately 100 metres west

of the Main Zone pit on section 16N. This hole intersected 298 metres of 0.31% copper and 0.26 g/t gold from 446 metres

that included a higher-grade interval of 52 metres of 0.75% copper and 0.51 g/t gold from 458 metres, and a 346.4 metre

interval of 0.33% copper and 0.31 g/t gold from 852 metres (see Figure 26, cross section 16N).

The East Ridge minerali zed corridor (>0.4% copper and >0.4 g/t gold) extends over 900 metres long, up to 1 ,000 metres

high and 125 metres wide, with higher-grade (>0.8% copper and >0.8 g/t gold) in several smaller pods over an area 500

metres high, 400 metres long and 100 metres wide.

These results demonstrate further support of the upside range of the Exploration Target defined in the June 2022 Newcrest

Quarterly Exploration Report date d 21 July 2022. The Exploration Target potential quantity and grade is conceptual in

nature; there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will

result in the estimation of a Mineral Resource.

Jim Miller-Tait, P.Geo. Vice President Exploration with Imperial Metals , is the designated Qualified Person as defined by

National Instrument 43-101 for the Red Chris exploration program and has reviewed this news release. Red Chris samples

for the 2022 drilling reported were analyzed at Bureau Veritas Mineral Laboratories in Vancouver. A full QA/QC program

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

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

model and true width of significant assay intervals.
