Red Chris Production and Exploration Update

Vancouver | October 28, 2020 | Imperial Metals Corporation (the “Company”) (TSX:III) reports Red Chris metal production

for the 2020 third quarter was 22.2 million pounds copper and 18,052 ounces gold, as compared to 26.5 million pounds

copper and 22,057 ounces gold produced in the 2020 second quarter.

Imperial’s 30% portion of Red Chris third quarter production was 6.66 million pounds copper and 5,415 ounces gold.

Newcrest Red Chris Mining Limited is operator of the Red Chris Joint Venture (Newcrest 70%; Imperial 30%).

Metal production was lower than the prior quarter reflecting a higher proportion of lower grade stockpile material being

fed to the mill due to unseasonal rainfall. This impacted the availability of higher grade mill feed from the pits, and resulted

in lower recoveries. Lower grades and recoveries were partially offset by a 13% increase in mill throughput.

To date, Red Chris has not experienced any COVID-19 related disruptions to the supply of goods or services, to its workforce

or to its operations.

Red Chris - Exploration Update

Results from the East Zone drilling program continue to confirm the presence of multiple discrete high grade pods of

mineralization. Infill resource definition hole RC634 returned 514 metres grading 1.3 g/t gold and 0.77% copper from 650

metres, including 166 metres^^ grading 3.0 g/t gold and 1.5% copper from 806 metres. Hole RC638 returned 488 metres

grading 0.61 g/t gold and 0.50% copper from 536 metres, including 104 metres grading 1.0 g/t gold and 0.76% copper from

646 metres. A total of 86,366 metres of drilling from 69 drill holes has been completed since August 2019.

Drilling during the third quarter continued to confirm the footprint of the western high grade pod, which was first

intersected in RC616. Results from a program of 100 metre spaced holes, designed to confirm the lateral and vertical extent

of this zone, include results from holes RC625 (previously reported) and RC637.

Final results for step-out hole RC625, located 100 metres south west of RC616, returned 426 metres^^ grading 0.62 g/t gold

and 0.48% copper from 640 metres, including 60 metres^^ grading 2.2 g/t gold and 1.3% copper from 736 metres. Results

continued to confirm the high grade mineralization with RC637, located 100 metres above RC625, returning 446 metres

grading 0.51 g/t gold and 0.45% copper from 618 metres, including 60 metres grading 1.5 g/t gold and 1.1% copper from

694 metres. Drilling to define the extent and continuity of this high grade pod is ongoing. These discrete pods sit within the

larger footprint of the overall porphyry system.

The Brownfields Exploration program has been expanded with drilling underway across the East Zone, Main Zone and Gully

Zone, and will follow up on historic drilling results along a 3 kilometre segment of the porphyry corridor in search for zones

of mineralization which could support additional mining fronts.

A property wide Airborne Electro-Magnetic (AEM) and gravity survey have been completed. A high-resolution airborne

magnetics survey was also completed over a portion of the property to provide complete coverage. The survey aims to

generate drill targets across the entire claim package.

Jim Miller-Tait, P.Geo., Imperial VP Exploration, 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 2020 drilling reported were

analysed 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.
