VANCOUVER, British Columbia and SYDNEY, Australia, June 14, 2023 (GLOBE NEWSWIRE) --
Patriot Battery Metals Inc. (the “Company” or “Patriot”) (TSX-V: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA)
is pleased to announce core assays for the next series of drill holes completed as part of the 2023 winter drill program, which recently concluded at its wholly owned Corvette Property (the “Property”), located in the Eeyou Istchee James Bay region of Quebec. The winter phase of the 2023 drill campaign was focused on the CV5 Pegmatite, located approximately 13.5 km south of the regional and all-weather Trans-Taiga Road and powerline infrastructure.
Core assays, for the drill holes reported herein (Figure 1), cover the CV5 Pegmatite’s recently defined eastward extension (see news releases dated
February 5
and
March 23, 2023
) (Figure 2), the high-grade Nova Zone (see news release dated
May 16, 2023
) (Figure 2), and the recently defined westward extension (see news release dated
May 1, 2023
) (Figure 3).
Drill hole CV23-148 targeted the Nova Zone and returned a wide and high-grade intercept of
95.3 m at 1.62% Li
2
O
, including
47.6 m at 2.09% Li
2
O
or
4.1 m at 4.44% Li
2
O
. The high-grade result affirms the interpretation that the Nova Zone extends continuously over a strike length of at least 1.1 km – from drill holes CV23-132 to 108 (Figures 1 and 2).
Strong grades and widths were returned in drilling over the recently defined westward extension (Figure 3), highlighted by drill hole CV23-160A, which returned
127.7 m at 1.78% Li
2
O
, including
50.1 m at 2.43% Li
2
O.
Other drill holes in this area, with assays reported herein, include CV23-172 (
13.2 m at 1.14% Li
2
O
,
and
15.7 m at 0.94% Li
2
O
), CV23-182 (
14.8 m at 1.06% Li
2
O
), and CV23-187 (
14.1 m at 1.19% Li
2
O
). Additionally, drill hole CV23-174, located proximal to the westward extension, returned a strong intercept of
44.2 m at 0.99% Li
2
O
, including
15.3 m at 2.58% Li
2
O
.
Drill core sample assays for two (2) holes remain to be reported over the westward extension area of the CV5 Pegmatite (Figure 1). This includes a continuous 93 m interval of dominantly spodumene-bearing pegmatite in the most westerly drill hole completed through the end of the winter program (CV23-184), and a continuous 139 m interval of dominantly spodumene-bearing pegmatite in the final drill hole of the 2023 winter program (CV23-190).
Assay results for holes reported herein over the far eastern portion of CV5 (Figure 2), as is currently defined, returned variable grades and widths of lithium mineralized pegmatite. Results include 51.2 m at 0.59% Li
2
O, including
10.1 m at 0.87% Li
2
O
and
9.3 m at 0.91% Li
2
O
(CV23-154), and 27.5 m at 0.40% Li
2
O, including
3.2 m at 2.22% Li
2
O
(CV23-156). Internal fractionation commonly leads to lower-grade pegmatite being immediately adjacent to higher-grade pegmatite. Considering the wide and continuous widths of pegmatite in these holes (CV23-154 and 156), at 49.9 m and 27.5 m, respectively, the grades returned are very encouraging with respect to the potential for additional and proximal higher-grade zones to be present. The pegmatite in this area remains open up-dip, down-dip, and along strike eastwardly.
Through the 2023 winter drill program, the CV5 Pegmatite has
been traced continuously by drilling
(at approximately 50 to 150 m spacing) as a principally continuous spodumene-mineralized body
over a lateral distance of at least 3.7 km
and
remains open
along strike at both ends and to depth along most of its length.
The Company remains on target for a July 2023 announcement for the initial mineral resource estimate at CV5, which will include all drill holes completed through April 17, 2023 (i.e., the recently completed winter drill program). The timing of the announcement remains dependent on timely receipt of the final outstanding core sample assays from the laboratory, as well as final database and model validation.
Core sample assay results for drill holes reported herein are presented in Table 1. Core assay results remain to be reported for twelve (12) drill holes completed during the winter program, with all drill core samples having arrived at the analytical lab (SGS). Drill holes locations are available from the Company’s website as well as news release dated
May 16, 2023
. Select core photos are presented in Figures 4 and 5.
Figure 1: Drill holes completed at the CV5 Pegmatite through the 2023 winter drill program
A Quality Assurance / Quality Control protocol following industry best practices was incorporated into the program and included systematic insertion of quartz blanks and certified reference materials into sample batches, as well as collection of quarter-core duplicates, at a rate of approximately 5%. Additionally, analysis of pulp-split and coarse-split sample duplicates were completed to assess analytical precision at different stages of the laboratory preparation process, and external (secondary) laboratory pulp-split duplicates were prepared at the primary lab for subsequent check analysis and validation.
All core samples collected were shipped to SGS Canada’s laboratory in Val-d’Or, QC, for standard sample preparation (code PRP89) which includes drying at 105°C, crush to 75% passing 2 mm, riffle split 250 g, and pulverize 85% passing 75 microns. The pulps were shipped by air to SGS Canada’s laboratory in Burnaby, BC, where the samples were homogenized and subsequently analyzed for multi-element (including Li and Ta) using sodium peroxide fusion with ICP-AES/MS finish (codes GE_ICP91A50 and GE_IMS91A50).
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 3.7 km long spodumene pegmatite (the ‘CV5 Pegmatite’) and multiple proximal secondary spodumene pegmatite lenses.
To date, six (6) distinct clusters of lithium pegmatite have been discovered across the Corvette Property – CV5 Pegmatite and associated lenses, CV4, CV8-12, CV9, CV10, and 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 bodies, with significant lateral and depth extent, to be present.

Appendix 1 – JORC Code 2012 Table 1 information required by ASX Listing Rule 5.7.1
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.
Core Sampling is guided by lithology as determined during geological logging (i.e., by a geologist). All pegmatite intervals are sampled in their entirety (half-core), regardless if spodumene mineralization is noted or not (in order to ensure an unbiased sampling approach) in addition to ~1-3 m of sampling into the adjacent host rock (dependent on pegmatite interval length) to “bookend” the sampled pegmatite.
The minimum individual sample length is 0.3 m and the maximum sample length is 3.0 m. Targeted individual pegmatite sample lengths are 1.0 m.
All drill core is oriented to maximum foliation prior to logging and sampling and is cut with a core saw into half-core pieces, with one half-core collected for assay, and the other half-core remaining in the box for reference.
Core samples collected were shipped to SGS Canada’s laboratory in Val-d’Or, QC, for standard sample preparation (code PRP89) which includes drying at 105°C, crush to 75% passing 2 mm, riffle split 250 g, and pulverize 85% passing 75 microns. The pulps were shipped by air to SGS Canada’s laboratory in Burnaby, BC, where the samples were homogenized and subsequently analyzed for multi-element (including Li and Ta) using sodium peroxide fusion with ICP-AES/MS finish (codes GE_ICP91A50 and GE_IMS91A50).
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).
NQ or HQ size core diamond drilling was completed for all holes. Core is not oriented; however, downhole OTV-ATV surveys have been completed on some prior holes to assess overall structure.
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.
All drill core was geotechnically logged following industry standard practices, and includes total core recovery, fracture recording, ISRM rock strength and weathering, and RQD. Core recovery is very good and typically exceeds 90%.
Logging
Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.
The total length and percentage of the relevant intersections logged.
Upon receipt at the core shack, all drill core received is pieced together, oriented to maximum foliation, metre marked, geotechnically logged (including structure), alteration logged, geologically logged, and sample logged on an individual sample basis. Core box photos are also collected of all core drilled, regardless of perceived mineralization. Specific gravity measurements are also collected at systematic intervals for all drill core.
These logging practices meet or exceed current industry standard practices and are of appropriate detail to support a mineral resource estimation.
The logging is qualitative by nature, and includes estimates of spodumene grain size, inclusions, and model mineral estimates.
Sub-sampling techniques and sample preparation
If core, whether cut or sawn and whether quarter, half or all core taken.
If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.
For all sample types, the nature, quality and appropriateness of the sample preparation technique.
Quality control procedures adopted for all 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.
Drill core sampling follows industry best practices. Drill core was saw cut with half-core sent for geochemical analysis and half-core remaining in the box for reference. The same side of the core was sampled to maintain representativeness. Additionally, several intervals over several holes have had quarter-core samples collected for mineral processing programs, thus leaving only a quarter-core in the box for reference over these intervals.
Sample sizes are appropriate for the material being assayed.
A Quality Assurance / Quality Control protocol following industry best practices was incorporated into the program and included systematic insertion of quartz blanks and certified reference materials into sample batches, as well as collection of quarter-core duplicates, at a rate of approximately 5%. Additionally, analysis of pulp-split and course-split sample duplicates were completed to assess analytical precision at different stages of the laboratory preparation process, and external (secondary) laboratory pulp-split duplicates were prepared at the primary lab for subsequent check analysis and validation.
All protocols employed are considered appropriate for the sample type and nature of mineralization and are considered the optimal approach for maintaining representativeness in sampling.
Quality of assay data and laboratory tests
The nature, quality and appropriateness 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.
Core samples collected were shipped to SGS Canada’s laboratory in Val-d’Or, QC, for standard sample preparation (code PRP89) which includes drying at 105°C, crush to 75% passing 2 mm, riffle split 250 g, and pulverize 85% passing 75 microns. The pulps were shipped by air to SGS Canada’s laboratory in Burnaby, BC, where the samples were homogenized and subsequently analyzed for multi-element (including Li and Ta) using sodium peroxide fusion with ICP-AES/MS finish (codes GE_ICP91A50 and GE_IMS91A50).
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.
The Company relies on both its internal QAQC protocols (systematic quarter-core duplicates, blanks, certified reference materials, and external checks), as well as the laboratory’s internal QAQC.
For assay results disclosed, samples have passed QAQC review.
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.
Intervals are reviewed and compiled by the VP Exploration and Project Managers prior to disclosure, including a review of the Company’s internal QAQC sample analytical data.
No twinned holes have been completed, apart from CV23-166, which was re-collared as a different core size, as well as some holes that were lost prior to hitting their target depth, which were re-collared a few metres adjacent.
Data capture utilizes MX Deposit software whereby core logging data is entered directly into the software for storage, including direct import of laboratory analytical certificates as they are received. The Company employs various on-site and post QAQC protocols to ensure data integrity and accuracy.
Adjustments to data include reporting lithium and tantalum in their oxide forms, as it is reported in elemental form in the assay certificates. Formulas used are Li2O = Li x 2.1527, and Ta2O5 = Ta x 1.2211
Location of data points
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.
Specification of the grid system used.
Quality and adequacy of topographic control.
Each drill hole’s collar has been surveyed with a handheld GPS or RTK (Topcon GR5 or Trimble Zephyr 3).
The coordinate system used is UTM NAD83 Zone 18.
The Company completed a property-wide LiDAR and orthophoto survey in August 2022, which provides high-quality topographic control.
The quality and accuracy of the topographic controls are considered adequate for advanced stage exploration and development.
Data spacing and distribution
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.
Whether sample compositing has been applied.
Drill hole spacing is dominantly at ~100 m; however, tightens to ~50 m in some places, and widens to ~150 in a small number of places.
Based on the nature of the mineralization and continuity in geological modelling, it is believed that a 100 m spacing will be sufficient to support a mineral resource estimate.
Core sample lengths typically range from 0.5 to 1.5 m and average ~1 m. Sampling is continuous within all pegmatite encountered in drilling.
Sample compositing has not been applied
Orientation of data in relation to geological structure
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.
No sampling bias is anticipated based on structure within the mineralized body.
The mineralized body is relatively undeformed and very competent, although likely has some meaningful structural control.
The mineralized body is steeply dipping resulting in oblique angles of intersection with true widths varying based on drill hole angle and orientation of pegmatite at that particular intersection point. i.e. The dip of the mineralized pegmatite body has variations in a vertical sense and along strike, so the true widths are not always apparent until several holes have been drilled in any particular drill-fence.
Sample security
The measures taken to ensure sample security.
Samples were collected by Company staff or its consultants following specific protocols governing sample collection and handling. Core samples were bagged, placed in large supersacs for added security, palleted, and shipped directly to Val-d’Or, QC, being tracked during shipment along with Chain of Custody. Upon arrival at the laboratory, the samples were cross-referenced with the shipping manifest to confirm all samples were accounted for. At the laboratory, sample bags are evaluated for tampering.
Audits or reviews
The results of any audits or reviews of sampling techniques and data.
A review of the sample procedures for the Company’s 2021 fall drill program (CF21-001 to 004) and 2022 winter drill program (CV22-015 to 034) was completed by an Independent Qualified Person and deemed adequate and acceptable to industry best practices (discussed in an “NI 43-101 Technical Report on the Corvette Property, Quebec, Canada”, Issue date of June 27
th
, 2022.) Additionally, the Company continually reviews and evaluates its procedures in order to optimize and ensure compliance at all levels of sample data collection and handling.

Geology
Deposit type, geological setting and style of mineralisation.
The Property is situated within the Lac Guyer Greenstone Belt, considered part of the larger La Grande River Greenstone Belt and is dominated by volcanic rocks metamorphosed to amphibolite facies. The claim block is dominantly underlain by the Guyer Group (basaltic amphibolite, iron formation) and the Corvette Formation (amphibolite of intermediate to mafic volcanics). Several occurrences of ultramafic rocks (peridotite, pyroxenite, komatiite) as well as felsic volcanics (tuffs) are also mapped over areas of the Property. The basaltic amphibolite rocks that trend east-west (generally south dipping) through this region are bordered to the north by the Magin Formation (conglomerate and wacke) and to the south by an assemblage of tonalite, granodiorite, and diorite. Several regional-scale Proterozoic gabbroic dykes also cut through portions of the Property (Lac Spirt Dykes, Senneterre Dykes).
The geologic setting is prospective for gold, silver, base metals, platinum group elements, and lithium over several different deposit styles including orogenic gold (Au), volcanogenic massive sulfide (Cu, Au, Ag), komatiite-ultramafic (Au, Ag, PGE, Ni, Cu, Co), and pegmatite (Li, Ta).
Exploration of the Property has outlined three primary mineral exploration trends crossing dominantly east-west over large portions of the Property – Maven Trend (copper, gold, silver), Golden Trend (gold), and CV Trend (lithium, tantalum). Lithium mineralization at the Property is observed to occur within quartz-feldspar pegmatite (LCT Pegmatites), often exposed at surface as high relief ‘whale-back’ landforms. The pegmatite is often very coarse-grained and off-white in appearance, with darker sections commonly composed of mica and smoky quartz, and occasional tourmaline.
The lithium pegmatites at Corvette are LCT Pegmatites. Core assays and ongoing mineralogical studies, coupled with field mineral identification and assays, indicate spodumene as the dominant lithium-bearing mineral on the Property, with no significant petalite, lepidolite, lithium-phosphate minerals, or apatite present. The pegmatites at Corvette also carry significant tantalum values with tantalite indicated to be the mineral phase.
Drill hole Information
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
easting and northing of the drill hole collar
elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
dip and azimuth of the hole
down hole length and interception depth
hole length.
If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.
Drill hole attribute information for the drill holes with core assay data announced herein are available on the Company’s website and in news released dated May 16, 2023.
Grade over width calculations for assays of intervals of <2 m are not typically presented as they are considered insignificant.
Data aggregation methods
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.
Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
The assumptions used for any reporting of metal equivalent values should be clearly stated.
Length weighted averages were used to calculate grade over width.
No specific grade cap or cut-off was used during grade width calculations. The lithium and tantalum average of the entire pegmatite interval is calculated for all pegmatite intervals over 2 m core length, as well as higher grade zones at the discretion of the geologist. Pegmatites have inconsistent mineralization by nature, resulting in most intervals having a small number of poorly mineralized samples throughout the interval included in the calculation. Non-pegmatite internal dilution is limited to typically <3 m where relevant intervals indicated where assays are reported.
No metal equivalents have been reported.
Relationship between mineralisation widths and intercept lengths
These relationships are particularly important in the reporting of Exploration Results.
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).
Geological modelling is ongoing; however, current interpretation supports a large pegmatite body (CV5) of near vertical to steeply dipping orientation, flanked by several secondary pegmatite lenses.
All reported widths are core length. True widths are not well constrained and may vary widely from hole to hole based on the drill hole angle and the highly variable nature of pegmatite bodies, which tend to pinch and swell aggressively along strike and to depth. i.e. The dip of the mineralized pegmatite body has variations in a vertical sense and along strike, so the true widths are not always apparent until several holes have been drilled in any particular drill-fence.
Diagrams
Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.
Please refer to the figures included herein as well as those posted on the Company’s website.
Balanced reporting
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.
Please refer to the table(s) included herein as well as those posted on the Company’s website.
Results for every individual pegmatite interval that is greater than 2 m has been reported.
Other substantive exploration data
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.
The Company is currently completing baseline environmental work over the CV5 Pegmatite area. No endangered flora or fauna have been documented over the Property to date, and several sites have been identified as potentially suitable for mine infrastructure.
The Company has completed a bathymetric survey over the shallow glacial lake which overlies a portion of the mineralized body. The lake depth ranges from <2 m to approximately 18 m, and is typically less than 10 m over the mineralized body.
The Company has completed preliminary metallurgical testing comprised of HLS and magnetic testing, which has produced 6+% Li2O spodumene concentrates at >70% recovery. A DMS test followed returning a spodumene concentrate grading 5.8% Li2O at 79% recovery. The data suggests potential for a DMS only operation to be applicable to the project.
Various mandates required for advancing the Project towards economic studies have been initiated, including but not limited to, metallurgy, geomechanics, hydrogeology, hydrology, stakeholder engagement, geochemical characterization, as well as transportation and logistical studies.
Further work
The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling).
Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
The Company intends to continue drilling the pegmatites of the Corvette Property, focused on the CV5 Pegmatite and adjacent secondary lenses. The mineralized pegmatites remain open along strike, and to depth at most locations along strike. Drilling is also anticipated to continue at the CV13 pegmatite cluster as well as other pegmatite clusters at the Property. The details of these programs are still being developed. An initial mineral resource estimate is anticipated to be completed for the CV5 Pegmatite in 2023.
