Patriot Battery Metals Inc.: New Spodumene Pegmatite Cluster Discovered ~20 km from the CV5 Deposit

March 25, 2025

Highlights

• Significant new spodumene pegmatite cluster discovered from surface exploration within the Shaakichiuwaanaan Property in Quebec, Canada.
• The new discovery, named “CV15”, sits along geological trend from the CV9-CV10-CV14 spodumene pegmatites and ~20 km west of the cornerstone CV5 Deposit:
  • Outcrop sample assays of 11% Li₂O, 1.55% Li₂O, and 1.02% Li₂O.
  • Multiple pegmatite outcrops identified over a 400 m x 200 m area to date.
  • Discovery extends the prospective “Mickel Trend” by ~1.9 km to ~5.5 km in length, which is longer than the CV5 Pegmatite (4.6 km).
  • The ~5 km long Mickel Trend starts ~9.5 km west of the CV13 Pegmatite, demonstrating the enormous scale and prospectivity of the Shaakichiuwaanaan Property.
• New LCT pegmatite outcrop also discovered ~525 m along strike from the CV8 Spodumene Pegmatite with sample assays including 2,282 ppm Ta₂O₅, significantly extending the local prospective LCT pegmatite trend.
• Additional subangular spodumene pegmatite boulders discovered to the northwest and southeast of the CV5 Deposit, highlighting the potential for additional spodumene pegmatites to be discovered under glacial till cover proximal to the currently known CV5 Deposit footprint.
• The 2024 outcrop and boulder discoveries, demonstrate the considerable discovery upside that remains over significant parts of the Shaakachiuwaanaan Property.

Darren L. Smith, Patriot Executive and Vice President of Exploration, comments: “The 2024 surface campaign at Shaakichiuwaanaan has delivered significant results which continue to demonstrate that we have still only scratched the surface in terms of the Property’s broader exploration potential. The discovery of another new spodumene pegmatite occurrence at CV15 – along the prospective Mickel Trend, which encompasses CV9, CV10, CV14, and CV15 – represents another exciting opportunity for the Company.”

“We are eager to follow-up this discovery with systematic surface exploration, including channeling and mapping, as the Mickel Trend has now been extended by ~1.9 km, from ~3.6 km to ~5.5 km. Coupled with the numerous spodumene pegmatite boulders over the Property, these discoveries highlight the extensive nature of the spodumene mineralized system at Shaakichiuwaanaan. There remains strong potential for additional discoveries,” added Mr. Smith.

Patriot Battery Metals Inc. (the “Company” or “Patriot”) (TSX: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) is pleased to announce the discovery of a new spodumene pegmatite cluster, CV15, from its 2024 surface exploration campaign at the wholly-owned Shaakichiuwaanaan Property (the “Property” or “Project”), located in the Eeyou Istchee James Bay region of Quebec.

The Shaakichiuwaanaan Property hosts a consolidated Mineral Resource Estimate[1] (“MRE”) of 80.1 Mt at 1.44% Li₂O Indicated and 62.5 Mt at 1.31% Li₂O Inferred. The CV5 Spodumene Pegmatite, which forms the bulk of the MRE, is accessible year-round by all-season road and is situated approximately 14 km from a major hydroelectric powerline corridor. The CV13 Pegmatite is located <3 km along geological trend from the CV5 Pegmatite, which hosts additional lithium and tantalum resources, as well as a recently discovered zone of cesium mineralisation (see news release dated March 2, 2025).

The 2024 surface exploration campaign included geological mapping, regional prospecting, and surface sampling and was focused on discovery of new lithium pegmatite occurrences across the Property outside of the existing deposits. A total of 647 surface rock grab/chip samples were collected during the course of the program.

CV15 Spodumene Pegmatite Discovery & the Mickel Trend

The 2024 program resulted in the discovery of a significant new spodumene pegmatite cluster at surface, named CV15, with outcrop grab sample assays including 2.11% Li₂O, 1.55% Li₂O, and 1.02% Li₂O. Additionally, grab sample assays from nearby boulders returned grades of 3.10% Li₂O and3.02% Li₂O. The CV15 discovery is situated approximately 1.9 km southwest and along geological trend from CV14, and collectively now forms part of a larger ~5.5 km long prospective trend extending from the CV9 spodumene pegmatite cluster to CV15, now referred to as the Mickel Trend (Figure 1 and Figure 2).

The CV15 discovery consists of multiple pegmatite outcrops spread over an approximate 400 m x 200 m area, with the largest measuring ~7 m x 6 m in size (Figure 3), and remains open in all directions. Like other spodumene pegmatite occurrences on the Property, spodumene crystals at CV15 are large and hosted in a smoky-quartz and feldspar groundmass (Figure 4). The discovery significantly enhances the prospectivity of the Mickel Trend – now ~5.5 km long – which also includes the CV9, CV10, and CV14 spodumene pegmatites.

Of the four (4) lithium pegmatite clusters situated along the ~5.5 km long Mickel Trend, only the CV9 Pegmatite – demarcating the currently known northeastern end of the trend (which remains open) – has been drill tested (see news release dated April 7, 2024). Results include 99.9 m at 0.39% Li₂O, including 30.6 m at 0.80% Li₂O (CV23-345), 10.8 m at 1.00% Li₂O (CV23-267), and 7.7 m at 1.35% Li₂O (CV23-333). The drilling confirmed the presence of widespread spodumene mineralization, which remains open along strike and to depth, while also demonstrating the potential for significant volumes with a thick (up to ~80 m true thickness) pegmatite dyke present.

The Company intends to follow-up at CV15 in 2025 with targeted prospecting and channel sampling.
