Drill Results

Imperial Mining Intersects 308 g//t Sc2O3 over 98.6 m, Including 322

g/t over 52.8 m at Crater Lake, Quebec

Highlights:

• Assay results from the three additional drillholes continue to return impressive grades of 98.6 (323.4’)

grading 308 g/t scandium oxide (Sc 2O3), including 52.8 m (173.2’) grading 322 g/t Sc2O3 and 113.7 m

(372.9) grading 2 78 g/t Sc2O3, including 335 g/t Sc2O3 over 10.5 m (34.4’) and including 301 g/t over

16.75 m (54.9’).

• These are the deepest cuts (150 m vertical) into the TG Zone and confirm a thickening and grade increase to

the mineralization at depth.

• Elevated levels of total rare earth oxides plus yttrium (TREO+Y) of up to 0. 479% characterize the

scandium-bearing horizon.

• At a gold price of $1,7 75US/oz and a scandium oxide price of $1, 500US/kg, the intersections represent a

gold-equivalent value of 7.3 to 8.8 g/t Au.

MONTREAL, QUEBEC – November 17, 2022 – Imperial Mining Group Ltd. ("Imperial") (TSX

VENTURE: IPG; OTCQB: IMPNF) is pleased to announce that it has received additional assays from

the Crater Lake summer drilling program on the TG scandium-rare earth mineralized zone. Assay results

have confirmed the substantial intersection widths of scandium-bearing olivine ferrosyenite (Table 1 and

2) reported earlier ( see Imperial Mining Press Release - OCT 20, 2022 ). The drilling program was

completed in early September. Once all results have been received from the Lab and compilation of the

data completed, Imperial plans to undertake an updated 43-101 Resource Estimate for the Zone. The new

data plans to convert the Inferred Category Resources reported late last year ( see Imperial Mining Press

Release - SEP 23, 2021) into Indicated/Measured Resources.

“The summer drilling results for the Crater Lake property continue to exceed all expectations , as they

continue to confirm wide intervals of scandium and TREO+Y at the T GZ target ,” said Peter Cashin,

Imperial’s President & Chief Executive Officer. “ Drilling has now defined the Zone on 50 m sections

between Sections 350N and 600N and mineralization has been traced by drilling over 600m in total strike

length from surface to a vertical depth of 150 m (Figure 1). Importantly, the zone appears to get wider and

higher grade with depth. We anticipate that the resource will likely increase from what was previously

reported for the TG.”

CURRENT DRILLING

To date, assays for three additional holes for 648.0 m have been received (Table 2, Figure 1). All drillholes

have intersected the target mafic intrusive host rock. The drilling indicates that the TG scandium Zone is

doubly dipping between 83 0 west to 70 0 east, with a north -northeast strike direction. The widths of the

mineralized zone vary between 55 and 135 m (180-443’) in true thickness. Mineralization is open at depth

below the 200 m vertical level and along strike and appears as a thickening, conical-shaped body in cross-

section.

QA-QC Protocol

Strict QA/QC protocols have been implemented for the Crater Lake Project, including the insertion of

certified reference materials (standards), duplicates and blanks at regular intervals throughout the sequence

of samples.

A total of 500 drillcore samples, including 35 QA-QC samples, were sent to Activation Laboratories Ltd.

All sample preparation and analytical work will be carried out at their facilities in Ancaster, Ontario. Several

analytical techniques were used to characterize the samples, which are combined at Actlabs into the

analytical package “8 -REE”. This package inclu des whole -rock and trace element analytic techniques.

Whole Rock analyses are done via a lithium metaborate/tetraborate fusion inductively coupled plasma (ICP)

finish. Trace elements are also analyzed by fusion ICP/MS.

The technical content in this press r elease was prepared, reviewed and certified by Pierre Guay, P. Geo.,

Imperial's Vice-President, Exploration, a Geologist and Qualified Person as defined by NI43-101.
