Patriot Battery Metals Inc. (TSX: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) is pleased to announce core assay results for drill holes completed in 2024 at the CV5 Spodumene Pegmatite. The Corvette Property, wholly owned by the Company, is located in the Eeyou Istchee James Bay region of Quebec. The CV5 Spodumene Pegmatite, with a maiden mineral resource estimate of 109.2 Mt at 1.42% Li₂O inferred¹, is situated approximately 13.5 km south of the regional and all–weather Trans-Taiga Road and powerline infrastructure.

Darren L. Smith, Vice President of Exploration for the Company, comments: “The 2024 resource infill drilling at CV5 advanced very well over the recently completed winter program, with the first batch of assays producing some stellar results. The team has done a phenomenal job, and all remaining core samples are now at the lab for processing. We are now focused on refining the pegmatite geological model and domaining through integration of the core assay data as it comes in.

“The Company remains on schedule for a Q3 2024 update to the June 2023 maiden mineral resource estimate, which will include both the CV5 and CV13 spodumene pegmatites,” added Mr. Smith.

Drill results for 34 drill holes, completed during the recently completed 2024 winter drill program at the CV5 Spodumene Pegmatite, are reported herein (Figure 1). Highlights include:

• 126.3 m at 1.66% Li₂O, including 54.9 m at 2.50% Li₂O (CV24-374).
• 100.8 m at 1.97% Li₂O, including 69.8 m at 2.52% Li₂O (CV24-392).
• 90.2 m at 1.29% Li₂O and 48.5 m at 1.25% Li₂O (CV24-377).
• 94.9 m at 1.10% Li₂O, including 26.1 m at 2.16% Li₂O (CV24-378).
• 70.1 m at 2.44% Li₂O, including 46.9 m at 3.53% Li₂O or 16.1 m at 5.02% Li₂O (CV24-401A).

The 2024 winter drill program at CV5 focused on resource infill and covered ~3.9 km of the total 4.6 km pegmatite strike length defined to date. The primary objective of the infill drilling is to improve the confidence of the geological model at CV5 to support an upgrade of mineral resources from the inferred category to the indicated category. This includes the delineation of a coherent body of indicated mineral resources to support advanced development and pending economic studies at CV5.

The drill hole results announced herein continue to demonstrate strong grades and continuity of spodumene pegmatite at CV5. In particular, drill hole CV24-374 returned a significantly wider interval of pegmatite than initially modelled based on the June 2023 MRE – 126.3 m (at 1.66% Li₂O) intercept versus an expected 86 m intercept, as predicted by the June 2023 MRE’s geological model. This additional metreage was also returned from outside of the conceptual pit constraint used in the June 2023 MRE and indicates an area of potential resource growth along strike at this depth in this area (Figure 2).

Additionally, at the far east end of the high-grade Nova Zone, situated between and at a similar depth to drill holes CV23-107 (37.1 m at 2.09% Li₂O, including 3.0 m at 5.43% Li₂O) and CV23–108 (26.6 m at 2.44% Li₂O, including 5.0 m at 4.30% Li₂O), hole CV24-401A returned a significantly wider, higher-grade intercept than expected – 46.9 m at 3.53% Li₂O including 16.1 m at 5.02% Li₂O within a wider high-grade zone of 70.1 m at 2.44% Li₂O (Figure 3 and Figure 4).

The 2024 winter drill program, which concluded in mid-April at the Property, totalled 62,518 m (166 holes) – 50,961 m (121 holes) at CV5, and 11,557 m (45 holes) at CV13, of which 46,933 m (132 holes) remain to be reported. Core samples for all drill holes completed during the program have now arrived at the laboratory with analytical processing underway. The infill drill program at CV5 is scheduled to resume early summer and continue into the fall of this year.

An updated MRE for the Corvette Project, incorporating drilling through April 2024, is scheduled for Q3 2024. This MRE update will include both the CV5 and CV13 spodumene pegmatites and a total anticipated metreage of 134,129 m (369 holes) and 29,121 m (133 holes), respectively.

Collectively, through April 2024, drilling has traced the CV5 Spodumene Pegmatite over a strike length of 4.6 km, which remains open along strike at both ends and to depth over a significant portion of its length.

Core sample assays for drill holes reported herein from the CV5 Spodumene Pegmatite are presented in Table 1 for all pegmatite intersections >2 m. Drill hole locations and attributes are presented in Table 2.

Quality Assurance / Quality Control

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, for sample preparation (code PRP89 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 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.
