PATRIOT DRILLS 122.6 M AT 1.89% LI2O, INCLUDING 8.1 M AT 5.01% LI2O, AND EXTENDS HIGH-GRADE NOVA ZONE, AT THE CV5 PEGMATITE, CORVETTE PROPERTY, QUEBEC, CANADA

Patriot Battery Metals Inc. has released 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, 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 kilometres south of the regional and all-weather Trans-Taiga Road and power line infrastructure.

Highlights

• Additional high-grade zone discovered, marking interpreted western extension of the Nova zone -- drill holes CV23-130, 132, 134 and 138:
  • 122.6 metres at 1.89 per cent Li2O (126.0 m to 248.5 m), including 8.1 m at 5.01 per cent Li2O (CV23-138);
  • 130.3 m at 1.56 per cent Li2O (164.0 m to 294.3 m), including 52.7 m at 2.45 per cent Li2O (CV23-132);
  • 101.3 m at 1.44 per cent Li2O (123.3 m to 224.6 m), including 28.1 m at 3.00 per cent Li2O (CV23-134);
  • 101.2 m at 1.08 per cent Li2O (145.5 m to 246.7 m), including 10.1 m at 2.42 per cent Li2O and 4.0 m at 4.13 per cent Li2O (CV23-130).
• Other significant intercepts
  • 101.2 m at 1.59 per cent Li2O (240.3 m to 341.5 m), including 28.5 m at 4.14 per cent Li2O or 8.8 m of 5.20 per cent Li2O (CV23-141);
  • 56.3 m at 2.34 per cent Li2O (251.4 m to 307.6 m), including 11.1 m at 4.06 per cent Li2O (CV23-114);
  • 57.7 m at 1.46 per cent Li2O (182.0 m to 239.7 m), including 13.3 m at 2.65 per cent Li2O (CV23-168A);
  • 43.5 m at 1.80 per cent Li2O (239.5 m to 283.0 m), and 24.0 m at 2.04 per cent Li2O (372.9 m to 396.9 m) (CV23-127).
• A continuous 93 m interval of dominantly spodumene-bearing pegmatite in most westerly drill hole completed to date at the CV5 pegmatite -- CV23-184 (assays pending).
• A continuous 139 m interval of dominantly spodumene-bearing pegmatite in final drill hole of the 2023 winter program at the CV5 pegmatite -- CV23-190 (assays pending).
• Core sample assay results for 27 drill holes completed during the 2023 winter drill program remain to be reported.

Blair Way, company president and chief executive officer, comments: "The drill bit continues to deliver for us as confirmed by the strong grades and wide widths of mineralized pegmatite reported herein. With our last hole providing the longest pegmatite intersection of the winter drill program (139 m), we are certainly primed for continued success as we approach the beginning of our summer-fall drill program, scheduled to commence later this month. With core sample assays for numerous drill holes remaining to be received, the company's geological team is steadfast focused on final validation of the CV5 pegmatite's geological model, inclusive of all drill holes completed to date, ahead of an initial mineral resource estimate."

Core assays, for the drill holes reported herein, cover the CV5 pegmatite's recently defined eastward extension (see news releases dated Feb. 5 and March 23, 2023), the east-central area proximal to the CV1 outcrop, and the recently defined westward extension (see news release dated May 1, 2023).

The drill holes targeting the east-central area of the CV5 pegmatite were completed during the winter program to take advantage of more practical and cost-effective ground access. These drill holes were highly successful with mineralized pegmatite intervals of 122.6 m at 1.89 per cent Li2O, including 8.1 m at 5.01 per cent Li2O (CV23-138), 130.3 m at 1.56 per cent Li2O, including 52.7 m at 2.45 per cent Li2O (CV23-132), 101.3 m at 1.44 per cent Li2O, including 28.1 m at 3.00 per cent Li2O (CV23-134), and 10.1 m at 2.42 per cent Li2O, and 4.0 m at 4.13 per cent Li2O (CV23-130). These four drill holes define a new high-grade zone, which is interpreted to represent a continuous 200-plus m extension westward of the high-grade Nova zone (see news release dated March 29, 2023). Drill holes CV23-181 (108 m of continuous pegmatite) and CV23-148 (95 m of continuous pegmatite) tested the connection of the zones (in example, the area between), with assays pending for both. However, based on logged modal spodumene content, the high-grade Nova zone is now interpreted to extend continuously from at least drill hole CV23-132 to CV23-108, a distance of approximately 1,100 m.

Assay results for two drill holes completed over the recently discovered westward extension of the CV5 pegmatite (see news released dated May 1, 2023) confirm strong lithium grades over moderate to wide intervals in this area -- 38.4 m at 1.19 per cent Li2O, 7.8 m at 3.01 per cent Li2O, and 8.8 m at 1.29 per cent Li2O (CV23-176), and 33.4 m at 0.87 per cent Li2O, and 12.8 m at 1.25 per cent Li2O (CV23-161).

The CV5 pegmatite remains open along strike westwardly in this area with the westernmost drill hole completed to date (CV23-184) returning a continuous 93 m interval of dominantly spodumene-bearing pegmatite. Additionally, the final hole of the winter program (CV23-190), also completed in this area, returned a continuous 139 m interval of dominantly spodumene-bearing pegmatite -- the widest pegmatite intercept of the 2023 winter program at the CV5 pegmatite. Core sample analysis for both CV23-184 and 190 have not yet been reported. These drill holes were also completed in opposite directions across the CV5 pegmatite body, further attesting to the sizable blow-out (in example, sizable width) of the pegmatite in this area.

The 2023 winter drill program recently concluded with a total of 89 drill holes and 32,367 m completed -- drill holes CV23-105 through 190. Through the 2023 winter program, the CV5 pegmatite has now 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 kilometres (CV23-184 to CV23-125) and remains open along strike at both ends and to depth along most of its length.

Due to the continuity of the pegmatite confirmed by the 2023 winter drill program, all holes completed to date at the CV5 pegmatite (through CV23-190) will be included in the forthcoming mineral resource estimate. The company is targeting a July, 2023, announcement and is dependent on timely receipt of all outstanding core sample assays from the laboratory, as well as final database and model validation.

The company's summer-fall drill exploration program is scheduled to recommence in late May at the CV5 and CV13 pegmatites. The summer-fall surface program is scheduled to begin in early June and continue through late September.

Core sample assay results for drill holes reported herein are presented in the first attached table. Core assay results remain to be reported for 27 drill holes completed during the winter program, with all drill core samples having arrived at the analytical lab (SGS). pegmatite intervals greater than two m (core length) for all drill holes completed during the winter program are presented in the second attached table, and drill hole attributes presented in the third attached table. All three tables will be posted to the company's website shortly.

Quality assurance/quality control (QA/QC)

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 per cent. 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, Que., for standard sample preparation (code PRP89) which includes drying at 105 degrees, crush to 75 per cent passing two millimetres, riffle split 250 grams and pulverize 85 per cent passing 75 microns. The pulps were shipped by air to SGS Canada's laboratory in Burnaby, B.C., where the samples were homogenized and subsequently analyzed for multielement (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 distinct clusters of lithium pegmatite have been discovered across the property -- CV5 pegmatite and associated lenses, CV4, 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, subparallel and sizable spodumene-bearing pegmatite bodies, with significant lateral and depth extent, to be present.
