Imperial Mining Intersects 378 g/t Sc2O3 over 24.68 m in a New High-Grade Zone at Crater Lake, Quebec
Imperial Mining Intersects 378 g/t Sc2O3 over 24.68 m in a New
High-Grade Zone at Crater Lake, Quebec
Highlights:
• Assay results from the final three drillholes from the summer program have returned impressive grades of
378 g/t scandium oxide (Sc2O3) over 24.68 m (81.0’) in a new mineralized zone within a larger interval
grading 288 g/t scandium oxide (Sc2O3) over 82.57 m (270.9’) and 292 g/t Sc2O3 over 41.95 m (137.6’),
including 320 g/t Sc2O3 over 26.3 m (86.3’).
• These are the deepest and southernmost cuts into the TG Zone and confirm a thickening and grade increase
to the mineralization at depth and the development of a new, parallel, and higher-grade mineralized system.
• Elevated levels of total rare earth oxides plus yttrium (TREO+Y) of up to 0.506% characterize this new
scandium-bearing horizon.
• At a gold price of $1,7 90US/oz and a scandium oxide price of $1, 500US/kg, the intersections represent a
gold-equivalent value of 7.5 to 9.9 g/t Au.
MONTREAL, QUEBEC – December 14, 2022 – Imperial Mining Group Ltd. ("Imperial") (TSX
VENTURE: IPG; OTCQB: IMPNF ) is pleased to announce that it has received the remaining results
from the Crater Lake Summer 2022 drilling program on the TG scandium -rare earth mineralized zone.
Assay results continue to return substantial intersection widths of scandium -bearing olivine rich
ferrosyenite and a new, higher-grade scandium bearing pyroxene-rich ferrosyenite zone (Tables 1 and 2)
reported earlier ( see Imperial Press release - NOV 17-22). With all of the results in, Imperial plans to
undertake an updated 43-101 Mineral Resource Estimate with the goal of converting all of the Inferred
Mineral Resources into the Indicated or Measured Mineral Resources category (see Imperial Mining Press
Release - SEP 23, 2021).
“We are very pleased to see the development of a parallel, higher-grade mineralized scandium system as
we move towards the south towards what we call the Southern Lobe of the TG Zone ,” said Peter Cashin,
Imperial’s President & Chief Executive Officer. “ Importantly, this higher-grade system is showing better
continuity in terms of width and grade and remains open towards the south, at depth and, potentially, closer
to surface. Our future exploration plans will be to better define this new system.”
CURRENT DRILLING
All analytical results for the last three holes of the summer drilling program representing a total of 738.0 m
have been received (Tables 1 and 2, Figure 1). All drillholes have intersected the target scandium bearing
ferrosyenite host rock. The recent drilling indicates that the southern portion of the TG scandium Zone is
composed of two different Sc bearing ferrosyenites and hosts a higher proportion of the higher-grade
pyroxene-rich ferrosyenite. This new pyroxene-rich ferrosyenite mineralization is open to the south west
and at depth. Individual drill assay grades of up to 602 g/t Sc2O3 were returned from this new system. The
mineralization of both Sc -bearing ferrosyenite zones is open at depth below the 200 m vertical level and
along strike and appears to show great potential for additional scandium mineralization between Sections
Lines 0N and 350N, particularly closer to surface.

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 646 drillcore samples, including 45 QA-QC samples, were sent to Activation Laboratories Ltd.
All sample preparation and analytical work w as carried out at their facilities in North Bay and Ancaster,
Ontario. Several analytical techniques were used to characterize the samples, which are combined at
Actlabs into the analytical package “8-REE”. This package includes 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.
