Early Crater Lake Drill Results Return Better Than Expected Grades and Intersection Lengths – 79.7 meters at 311 g/t Scandium Oxide, 0.326% Rare Earths Oxides and Yttrium
October 20 2022 - 7:30AM
Imperial Mining Group Ltd. ("Imperial")
(
TSX VENTURE: IPG; OTCQB: IMPNF) is pleased to
announce that it has completed its Summer 2022 exploration and
definition diamond drill program on the Ta-Nb Target and the TG
Zone. Early results are encouraging and give inference to grade and
tonnage increases to the TG North Lobe Deposit resource (see
Imperial Press release - SEP 23, 2021).
The TG scandium mineralized Zone (the “Zone”)
continues to return substantial intersection widths of
scandium-bearing Olivine and Pyroxene Ferrosyenite (Table 1). The
drilling program was performed from July 8th to September 8th, with
a total of 8 drillholes having tested the different targets.
Partial analytical results were received but due to longer
turnaround processing by our laboratory service, several analyses
have yet to be received. All core samples from boreholes CLE22001
and from CL22056 to CL22062 have been sent out for analyses.
Results for the remaining drillholes are anticipated to be
delivered within eight to ten weeks of receipt at the lab.
Summer Drill Program
A total of 8 drillholes for 1,663.0 m have been
completed (Table 1, Figure 1). All drillholes at the TG Zone have
intersected the target mafic intrusive host rock (Ferrosyenite),
host to all scandium-rare earth mineralization on the property. The
drilling indicates that the TG scandium Zone is doubly dipping
between 830 west to 700 east, with a north-northeast
strike direction. The widths of the mineralized intersections
observed from the program vary between 78 and 105 m in true
thickness. Mineralization remains open at depth below the 250 m
vertical level and along strike and appears as a thickening,
conical-shaped body in cross-section.
TG Zone Definition Drilling
Program
The program completed seven diamond drill holes
totaling 1,588.0 m (Figure 1). The intent of the program was to
complete sufficient infilling drillholes to undertake a review of
the 43-101 Preliminary Resource Estimate of the TG Zone and to
convert most of all Inferred Mineral Resources (see Imperial Press
Release – SEP 23, 2021) into the Indicated Mineral Resources
category.
To date, assays have been received for borehole
CL22057, which returned 79.7 m (261.5 feet) grading 311 g/t
scandium oxide
(Sc2O3)
and 0.326% Total Rare Earths and Yttrium (TREO+Y). This
hole was drilled as a deep cut on Section 650N and intersected a
cumulative thickness of 83.7 m of Sc-bearing Olivine-rich
Ferrosyenite (OLFESYN) commencing at 55.5 m in the hole.
Of particular interest was the appearance of
higher frequency of higher-grade PXFESYN (Pyroxene-rich
Ferrosyenite) in the deeper intersections into the TG Zone (see
description of holes CL22061 and CL22062 in Table 2).

Crater Lake Extension Tantalum-Niobium
Target Drilling
CLE22001 – The hole was
drilled vertically (-900) to the north of the scandium target area
and intersected a few 10 to 30 cm thick felsic dikes cross-cutting
the Mistastin Rapakivi Granite. Alteration zones of up to 10 and 20
cm thick are encountered within the vicinity of the dikes. These
dikes are mostly observed at the top of the hole.
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 1,331 drillcore samples, including 92
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 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.
The technical content in this press release 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.

The hole intersected several sections of felsic and intermediate
syenites (mixing zone between syenites and Olivine-rich
Ferrosyenite (OLFESYN) and a continuous section of OLFESYN. |

m down the hole. |
CL22060 |
The upper approximate 100 meters intersected mostly felsic and
intermediate syenites. Several structurally significant zones below
122 m bordering the major intersections of OLFESYN. |
77.3 |
The hole was drilled as a deep cut and intersected OLFESYN
commencing at 98.2 m. The largest intersection returned 67.5 m of
OLFESYN, starting at 154.4 m depth. The hole also intersected a
major fault at 171.9 m. |
CL22061 |
The hole intersected several sections of felsic syenites as well as
a major fault above significant intersections of Pyroxene-Rich
