Patriot Achieves 79% Recovery in Dense Media Separation Test
Work on the CV5 Pegmatite, Corvette Property, Quebec
December 19, 2022 – Vancouver, BC, Canada
Highlights
• Preliminary Dense Media Separation (“DMS”) followed by magnetic separation on drill core from the CV5
Pegmatite produces marketable spodumene concentrate at high lithium recovery
o 79% recovery to produce 5.8% Li2O spodumene concentrate with low Fe2O3 (0.60%)
• Results affirm previous Heavy Liquid Separation (“HLS”) tests and indicate a strong potential for a DMS
driven flowsheet without the need of flotation
• An HLS screening program is nearing completion and will assess the liberation and recovery characteristics
at different locations of the CV5 Pegmatite along strike and at depth
Patriot Battery Metals Inc. (the “Company” or “Patriot”) ( TSX-V: PMET) (ASX: PMT) (OTCQX: PMETF)
(FSE: R9GA) is pleased to announce the results of preliminary Dense Media Separation (“DMS”) testwork on drill
core material collected from the CV5 spodumene pegmatite at the Corvette Property (the ‘Property’ or ‘Project’),
located in the James Bay Region of Quebec.

The metallurgical test program for the Project is being completed by SGS Canada Inc. at their facility in Lakefield,
ON, and is focused on industry standard and cost-effective processing techniques applicable to spodumene pegmatite.
The prior scoping Heavy Liquid Separation (“HLS”) test work indicates strong potential for DMS to be applicable to
the process flowsheet for the CV5 Pegmatite (see news release dated August 4 th, 2022) and therefore, a DMS
operational run was subsequently completed (Figure 2).
A total of approximately 143 kg of composited drill core, from drill holes CF21-001 and 002, was processed through
a DMS and magnetic separation circuit, producing approximately 20 kg of marketable spodumene concentrate
grading 5.8% Li2O at 79% recovery, and with a low iron content (0.60% Fe2O3) (Figure 1 and 2). Therefore, the
DMS process run was highly successful and affirms the preliminary results from the HLS tests as first reported in
news release dated August 4th, 2022.
Mineral Process Consultant and Project Steering Group member, Brett Grosvenor, comments:
“The results of this preliminary DMS testwork are impressive and more importantly they strongly support a simple
DMS processing plant without the need for flotation. The high recovery and grade achieved during this preliminary
DMS are on par or better than some of the world’s leading hard rock lithium developments that I have previously
been involved in. Maintaining a simple process flowsheet will ultimately assist with the approvals process and de-
risking of the operation of the Corvette Lithium Project.”
The coarse-grained nature of the mineralization at CV5 allows for strong mineral liberation and recovery at relatively
coarse crush sizes. For the CV5 Pegmatite this has resulted in high spodumene recoveries into the final DMS (+ non-
magnetic) concentrate at a coarse crush size of -9.5 mm. In lithium pegmatite mineral processing, a coarse crush size
is strongly preferred to a smaller crush size ( or grinding) as it requ ires a reduced power consumption and less
equipment. Additionally, the benefits of DMS (± magnetic separation) compared to flotation are considerable and
include relatively lower CAPEX and OPEX, reduced reagent needs, coarser product and tailings, quicker operational
start-up, and overall, less technical risk. Additionally, DMS is a much more environmentally sustainable process when
compared to traditional flotation intensive processes.
The next phase of the flowsheet development has been initiated and includes the collection of eleven (11), ~10 m core
length, quarter-core composite samples from different depths and locations laterally along the CV5 Pegmatite . The
samples will be used for a preliminary evaluation of process variability (spodumene liberation and recovery) at a
coarse crush size using the HLS test method. The results will provide a good indication as to the applicability of DMS
throughout the CV5 Pegmatite body as is currently defined.

About the CV Lithium Trend
The CV Lithium Trend is an emerging spodumene pegmatite district discovered by the Company in 2017 and spans
more than 25 -km across the Corvette Property. The core area includes an approximate 2 .2 km long spodumene
pegmatite (the ‘CV5 Pegmatite’) and multi ple proximal secondary spodumene pegmatite lenses. This corridor has
returned drill intercepts of 159.7 m at 1.65% Li 2O and 193 ppm Ta 2O5 (CV22-042), 152.8 m at 1.22% Li 2O and
138 ppm Ta2O5 (CV22-030), 86.2 m at 2.13% Li2O and 163 ppm Ta 2O5 (CV22-044), and 70.1 m at 2.22% Li2O and
147 ppm Ta2O5, including 40.7 m at 3.01% Li2O and 160 ppm Ta2O5 (CV22-017).
To date, six (6) distinct clusters of lithium pegmatite have been discovered across the Property – CV5 Pegmatite and
associated lenses , CV 4, CV8 -12, CV9, CV10, and the recently discovered CV13. Given the proximity of some
pegmatite outcrops to each other, as well as the shallow till cover in the area, it is probable that some of the outcrops
may reflect a discontinuous surface exposure of a single, larger pegmatite ‘outcrop’ subsurface. Further, the high
number of well -mineralized pegmatites along the trend indicate a strong potential for a series of relatively closely
spaced/stacked, sub -parallel, and sizable spodumene -bearing pegmatite bodi es, with significant lateral and depth
extent, to be present.

Section 1 – Sampling Techniques and Data
Criteria JORC Code explanation Commentary
Sampling
techniques
• Nature and quality of sampling (eg cut
channels, random chips, or specific
specialised industry standard
measurement tools appropriate to the
minerals under investigation, such as down
hole gamma sondes, or handheld XRF
instruments, etc). These examples should
not be taken as limiting the broad meaning
of sampling.
• Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any
measurement tools or systems used.
• Aspects of the determination of
mineralisation that are Material to the
Public Report.
• In cases where ‘industry standard’ work
has been done this would be relatively
simple (eg ‘reverse circulation drilling was
used to obtain 1 m samples from which 3
kg was pulverised to produce a 30 g
charge for fire assay’). In other cases
more explanation may be required, such
as where there is coarse gold that has
inherent sampling problems. Unusual
commodities or mineralisation types (eg
submarine nodules) may warrant
disclosure of detailed information.
• Core sampling protocols met or exceeded industry
standard practices
• The DMS sample was comprised of saw-cut,
quarter-core intervals and collected from drill
holes CF21-001 and 002
• The DMS sample was comprised of a total
242.5 m (core length) over (2) drill holes
separated by approximately 100 m (CV21-001
and 002) and is considered representative of the
material directly below the CV5 Pegmatite as it
includes most of the pegmatite intersection(s) in
those two holes.
Drilling
techniques
• Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast, auger,
Bangka, sonic, etc) and details (eg core
diameter, triple or standard tube, depth of
diamond tails, face-sampling bit or other
type, whether core is oriented and if so,
by what method, etc).
• The samples utilized quarter-core NQ size drill
core
Drill sample
recovery
• Method of recording and assessing core
and chip sample recoveries and results
assessed.
• Measures taken to maximise sample
recovery and ensure representative
nature of the samples.
• Whether a relationship exists between
sample recovery and grade and whether
sample bias may have occurred due to
preferential loss/gain of fine/coarse
material.
• N/a – metallurgical testing reported in this release
Logging • Whether core and chip samples have
been geologically and geotechnically
• N/a – metallurgical testing reported in this release

sub-sampling stages to maximise
representivity of samples.
• Measures taken to ensure that the
sampling is representative of the in situ
material collected, including for instance
results for field duplicate/second-half
sampling.
• Whether sample sizes are appropriate to
the grain size of the material being
sampled.
• Core sampling protocols met or exceeded industry
standard practices
• The DMS sample was comprised of saw-cut,
quarter-core intervals and collected from drill
holes CF21-001 and 002
• The DMS sample was comprised of a total
242.5 m (core length) over (2) drill holes
separated by approximately 100 m (CV21-001
and 002) and is considered representative of the
material directly below the CV5 Pegmatite as it
includes most of the pegmatite intersection(s) in
those two holes.
• Sample size is considered appropriate for the test
method at lab scale
Quality of
assay data
and
laboratory
tests

of the assaying and laboratory procedures
used and whether the technique is
considered partial or total.
• For geophysical tools, spectrometers,
handheld XRF instruments, etc, the
parameters used in determining the
analysis including instrument make and
model, reading times, calibrations factors
applied and their derivation, etc.
• Nature of quality control procedures
adopted (eg standards, blanks,
duplicates, external laboratory checks)
and whether acceptable levels of
accuracy (ie lack of bias) and precision
have been established.
• All core samples collected were shipped to SGS
Canada’s Metallurgical laboratory in Lakefield, ON

appropriate analytical method (NaO2 fusion
followed by ICP-OES) and ensuring adequate
QAQC was satisfied, and the Company has relied
upon such practice. SGS (Lakefield) is a well-
established metallurgical and analytical laboratory
serving mineral exploration industry and is
independent of the Company
• The assay techniques are considered appropriate
for the nature and type of mineralization present,
and result in a total digestion and assay for the
elements of interest
Verification
of sampling
and
assaying
• The verification of significant intersections
by either independent or alternative
company personnel.
• The use of twinned holes.
• Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.
• Discuss any adjustment to assay data.
