Patriot Battery Metals Inc. announced additional drill results from the 2023 program completed at the CV13 Spodumene Pegmatite, as well as recent infrastructure development supporting the ongoing 2024 drill program at the Corvette Property. The Corvette Property (the Property or Project), wholly owned by the Company, 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 of 109.2 Mt at 1.42% Li2O inferred1 and is situated approximately 13.5 km south of the regional and allweather Trans-Taiga Road and powerline infrastructure.

Drill results for 15 drill holes completed in 2023 at the CV13 Spodumene Pegmatite are reported herein. These holes primarily target the near-surface and downdip extension of the principal pegmatite body along its western limb, as well as the eastern limb. Results include: 22.5 m at 1.10% Li2O, including 15.2 m at 1.57% Li2O (CV23-300).

19.4 m at 1.20% Li2O (CV23-312). 16.1 m at 1.54% Li2O, including 7.2 m at 2.57% Li2O (CV23-319). 13.8 m at 1.16% Li2O (CV23-320).

The drilling continues to trace spodumene pegmatite at CV13 to the west-northwest along geological trend and remains open along strike and downdip in this area. Results remain to be reported for twelve (12) drill holes, covering approximately 300 m of strike, over the far portions of this western limb. The mineralized pegmatite in this area has a shallow northeasterly dip resulting in pegmatite being traced down dip for over 250 m with minimal drilling, while still only being approximately 100 m vertical depth below surface - see geological cross-section in, which includes drill holes CV23-305 and 312 as reported herein.

Results are also reported herein for one (1) hole completed in 2023 (CV23-300, noted below) within the apex of the regional host structure at CV13. One (1) drill hole (CV23-302) completed in 2023 remains to be reported from this area. 22.5 m at 1.10% Li2O, including 15.2 m at 1.57% Li2O (CV23-300).

Results reported herein for drill holes completed over the eastern limb of the CV13 Pegmatite (CV23-293, 299, 301, and 306) returned only minor intervals of pegmatite ranging from <2 m to 5.8 m (core length). However, the pegmatite remains well mineralized in drill holes CV23-299 (4.7 m at 1.38% Li2O) and CV23-293 (2.7 m at 1.10% Li2O). The pegmatite dyke thins in this area of the eastern limb; however, is confirmed to thicken moving northeasterly along strike as evidence from drill holes completed in 2022.

Results for six (6) drill holes completed in 2023 along the eastern limb of CV13 remain to be reported. The CV13 Pegmatite is currently interpreted to be characterized by a principal upper dyke and a secondary "lower" dyke, as well as several subordinate sub-parallel dykes, and are collectively geologically modelled to be shallowly dipping northerly. The principal dyke (the upper dyke), dips typically between 20-25° and has been traced at depth to at least 300 m down-dip (vertical depth from surface of approx.

140 m). The principal dyke at CV13 has been traced over a 2.3 km strike length, as defined by multiple outcrop exposures and drilling completed to date, and remains open along strike at both ends and to depth. In 2024, through February 22, approximately 23,000 m of drilling have been completed at Corvette - 21,200 m at CV5 and 1,800 m at CV13 - with ten (10) drill rigs active at site.

Two (2) of the ten (10) drill rigs are currently active at the CV13 Pegmatite. The drilling at CV13 is targeted to further delineate the principal pegmatite body along strike and downdip. An updated mineral resource estimate for the Corvette Project, including both the CV5 and CV13 spodumene pegmatites, is planned for Third Quarter 2024.

Core sample assays for drill holes reported herein are presented in Table 1 for all pegmatite intersections >2 m. Drill hole locations and attributes are presented in Table 2. For drill holes completed in 2023, results remain to be reported for the CV13 Pegmatite (20 holes), the CV5 Pegmatite (42 holes), and the CV9 Pegmatite (18 holes). The 2024 winter drill program is entirely ground supported, utilizing the all-season/winter road constructed by the Company, which extends south from KM-270 of the Trans-Taiga Road to the CV5 Spodumene Pegmatite. The winter portion of this road has been further extended westerly to support drilling at the CV13 Spodumene Pegmatite.

No helicopters are currently active at site due this infrastructure now emplaced and in daily use. The Company's exploration camp at KM-270 of the Trans-Taiga Road has been operational since early January at an initial 80-person capacity, with an anticipated increase to at least 132-person later in the year. After consultation with elders from the Cree Nation of Chisasibi by the tallyman and his family, the camp has recently been formally named the Shaakichiuwaanan Camp (pronounced Shaa-gi-chi-waa-nan), a Cree word meaning to climb up a hill or mountain.

The camp is located only 13 km directly north of the CV5 Pegmatite, thereby dramatically reducing the transport time of field staff to and from the drill area. The combination of the Company's exploration camp on the Trans-Taiga and direct access roads to the CV5 and CV13 pegmatites have dramatically reduced the costs of the drill program through more cost-effective staff movement, reduced transport time, reduced accommodation costs, and reduced time for drill moves. In addition to the camp and road infrastructure development, the Company anticipates completing a geomechanical drill program this winter at CV5.

Data from this drilling and sampling will provide key datapoints to assess pit slope stability and design. This work will be followed in the summer by an infrastructure and condemnation geotechnical drill program, which will include potential tailings and waste rock storage sites, process plant, and camp accommodations for operation. A phase II hydrogeological drill program at CV5 is also planned for the summer, which will build upon the preliminary hydrogeological model completed in 2023.
