July 7, 2024 – Vancouver, BC, Canada July 8, 2024 – Sydney, Australia

Highlights

• Significant expansion to the recently discovered high-grade Vega Zone at the CV13 Spodumene Pegmatite. Highlights from the 2024 winter drill program include:
  • 51.7 m at 1.77% Li2O, including 9.7 m at 5.16% Li2O (CV24-525).
  • 35.3 m at 2.40% Li2O, including 17.4 m at 3.12% Li2O (CV24-520).
  • 34.8 m at 1.87% Li2O, including 19.1 m at 3.17% Li2O (CV24-524).
  • 41.5 m at 2.00% Li2O, including 10.6 m at 3.50% Li2O (CV24-510).
• Vega Zone is interpreted to be relatively flat-lying to shallowly dipping and

near-surface, covering an area of ~380 m x 220 m with a true thickness of ~8 to 30+ m, hosted within a wider mineralized pegmatite body. It remains open in several directions.

• Results for all drill holes completed during the 2024 winter program have now been reported – 50,961 m (121 holes) at CV5 and 11,557 m (45 holes) at CV13.
• The Vega Zone is a key target for the ongoing summer-fall drill program, with the mineralization delineated to date remaining open in several directions.
• Patriot remains on schedule for a Mineral Resource Estimate update for the Corvette Project in August 2024, including both the CV5 and CV13 spodumene pegmatites.

Darren L. Smith, Patriot’s Vice President of Exploration comments, “The final holes from our recently completed winter drill program at CV13 confirm a significant discovery of high-grade spodumene pegmatite at the Vega Zone, with high-grade mineralisation now defined over a significant area.”

“With such high grades present at the Vega Zone – akin to what we see at the Nova Zone at CV5 – including a standout 9.7 m intercept grading over 5% Li2O, the new results clearly validate the considerable potential at CV13 as well as that of the larger mineralized system at Corvette. We intend to further delineate this discovery as part of our recently commenced summer-fall drill program”, added Mr. Smith.

Patriot Battery Metals Inc. (the “Company” or “Patriot”) (TSX: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) is pleased to announce the final batch of core assay results from the CV13 Spodumene Pegmatite from its 2024 winter drill program at the Corvette Property, including holes targeting the recently discovered high-grade Vega Zone.

Suite 700 - 838 W. Hastings Street, Vancouver, BC, Canada, V6C 0A6 www.patriotbatterymetals.com TSX: PMET / ASX: PMT / OTC: PMETF / FSE: R9GA The 100%-owned Corvette Property (the “Property” or “Project”) is located in the Eeyou Istchee James Bay region of Quebec. The CV13 Spodumene Pegmatite is located approximately 3 km west-southwest of the CV5 Spodumene Pegmatite, which hosts a maiden Mineral Resource Estimate (“MRE”) of 109.2 Mt at 1.42% Li2O Inferred¹ and is situated approximately 13.5 km south of the regional and all‑weather Trans-Taiga Road and powerline infrastructure.

Core assay results for 16 drill holes, completed during the 2024 winter drill program at the CV13 Spodumene Pegmatite, are reported in this announcement (Figure 2 and Table 1). This is the final batch of core assay results for CV13 drill holes from this program. Highlights, each from the Vega Zone, include:

• 51.7 m at 1.77% Li2O, including 9.7 m at 5.16% Li2O (CV24-525).
• 35.3 m at 2.40% Li2O, including 17.4 m at 3.12% Li2O (CV24-520).
• 34.8 m at 1.87% Li2O, including 19.1 m at 3.17% Li2O (CV24-524).
• 41.5 m at 2.00% Li2O, including 10.6 m at 3.50% Li2O (CV24-510).

These four drill holes (CV24-510, 520, 524, and 525) were completed as follow-up to the discovery hole at the Vega Zone (CV24-470), which returned 34.4 m at 2.90% Li2O, including 21.9 m at 3.58% Li2O (see news release dated May 6, 2024), and drill holes reported on June 10, 2024 (CV24-498, 499, 507, and 513).

The highest-grade intercept (of significant width) to date from CV13 is reported in this announcement from drill hole CV24-525 (9.7 m at 5.16% Li2O), which was the last drill hole to target the Vega Zone during the 2024 winter program (Figure 5). This drill hole contains five individual core samples (each ranging from 1.1 m to 2.0 m in width) with assays >5% Li2O, and nine samples >3% Li2O.

Geological modelling (see preliminary cross-sections in Figure 1, Figure 3, and Figure 4) indicates the Vega Zone to be relatively flat-lying to shallow dipping and near-surface (starting at ~100 m vertical depth from surface), covering an area of approximately 380 by 220 m (drill hole intercept to drill hole intercept) with an interpreted true thickness of ~8 to 30+ m, hosted within a wider moderately to strongly mineralized pegmatite body. The Vega Zone remains open in several directions following the 2024 winter drill program.

The high-grade Vega Zone at CV13 Pegmatite is situated approximately 6 km south-west and along geological trend of the high-grade Nova Zone at the CV5 Pegmatite. Both zones share several similarities including lithium grades and very coarse decimetre to metre size spodumene crystals (Figure 6). However, both pegmatite zones have distinct orientations whereby the Vega Zone is relatively flat-lying to shallow dipping while the Nova Zone is steeply dipping to vertical.

Along the western arm of CV13, drill hole CV24-506 demonstrates that the pegmatite remains mineralized and open at depth in this area with an intercept of 8.2 m at 1.14% Li2O (Figure 7). The principal pegmatite in this area dips north-easterly at approximately 25° and ranges in thickness from approximately 7 m to 19 m.

To date, the CV13 Spodumene Pegmatite, through outcrop and drill hole data, is confirmed to extend over a strike length of at least 2.3 km and down-dip for at least 400 m, and remains open at both ends and to depth.

Results for all drill holes completed during the 2024 winter program have now been reported – 50,961 m (121 holes) at CV5 and 11,557 m (45 holes) at CV13. An updated MRE for the Corvette Project, incorporating drilling through April 2024 (i.e., end of the 2024 winter drill program) at both the CV5 and CV13 pegmatites, is scheduled for August 2024.

A follow-up drill program at CV13, focused on further delineation of the high-grade Vega Zone, is currently underway as part of this summer-fall drill program. Approximately 10,000 m of drilling is under consideration targeting the CV13 Spodumene Pegmatite’s Vega Zone and the immediate corridor eastwards towards the CV5 Spodumene Pegmatite.

However, the primary focus and objective of the summer-fall program will be drilling at the CV5 Spodumene Pegmatite to support an increase in MRE confidence from the Inferred category to the Indicated category. This work is designed to underpin a Mineral Resource Estimate of sufficient scale and confidence (i.e., Indicated classification) to support the Feasibility Study for the Project, which is currently scheduled for completion in the second half of 2025.

Core sample assays for drill holes reported herein from the CV13 Spodumene Pegmatite are presented in Table 1 for all pegmatite intersections >2 m. Drill hole locations and attributes are presented in Table 2.

1 The CV5 Mineral Resource Estimate (109.2 Mt at 1.42% Li2O and 160 ppm Ta2O5 Inferred) is reported at a cut- off grade of 0.40% Li2O with effective date of June 25, 2023 (through drill hole CV23-190). Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. Largest lithium pegmatite resource in the Americas based on contained LCE.

Quality Assurance / Quality Control (QAQC)

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 at a rate of approximately 5%. Additionally, analysis of pulp-split sample duplicates was completed to assess analytical precision, 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, or Radisson, QC, for sample preparation (code PRP90 special) which includes drying at 105°C, crush to 90% 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 is interpreted to span more than 50 kilometres across the Corvette Property. The core area includes the approximate 4.6 km long CV5 Spodumene Pegmatite, which hosts a maiden Mineral Resource estimate of 109.2 Mt at 1.42% Li2O Inferred¹.

To date, eight (8) distinct clusters of lithium pegmatite have been discovered across the Corvette Property – CV4, CV5, CV8, CV9, CV10, CV12, CV13, and the recently discovered CV14. 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.
