December 14, 2022 – Vancouver, BC, Canada

Highlights

Significant Drill Intercepts

at shallow to mid-level depths over a significant strike length. Results include some of the highest individual

lithium sample grades returned to date in drill hole.

062) and 42.2 m at 300 ppm Ta2O5 (and 1.52% Li2O) (CV22-064)

• Drill h oles CV22 -063 and CV2 2-066 continue to extend mineralization to the east -northeast at the CV5

Pegmatite, flanked by several secondary lenses, traced over a strike length of at least 2,200 m . The

mineralization remains open along strike at both ends and to depth along most of the pegmatite length.

2023 Exploration and Development Program

• Drilling at the Property to re-commence in January 2023 with up to five (5) drill core rigs in February

• Permits have been received and construction underway for a winter road extending south from the Trans -

Taiga all-season road to the primary drill area at the CV5 Pegmatite, expediting the winter drill program and

reducing helicopter usage.

Patriot Battery Metals Inc. (the “Company” or “Patriot”) ( TSX-V: PMET) (ASX: PMT) (OTCQB: PMETF)

(FSE: R9GA) is pleased to announce core assay results for twelve (12) additional drill holes (CV22-046, 055, and

057 through 066) from its 2022 drill campaign at its wholly owned Corvette Property (the “Property”), located in the

James Bay Region of Quebec. The primary drill area is focused at the CV5 Pegmatite, located approximately 13.5 km

south of the regional and all-weather Trans-Taiga Road and powerline infrastructure.

Blair Way, Company President, CEO and Director, comments:

“The Corvette Property continues to deliver with these latest assay results, which include some of our highest grades

to date. In addition, the strike length of the CV5 Pegmatite system remains open in all directions with wide widths and

strong grades encountered along its currently defined 2.2 km length. I am happy to be back on track with regular

news releases of our assay results from the summer- fall drill program. With 38 holes yet to be received from the lab,

and re-commencement of drilling in January, we will have continuous news flow on the Property for some time”

The twelve (12) drill holes (NQ core size – 47.6 mm inside diametre) reported herein targeted mineralization at shallow

to mid-level depths over a significant strike length of the CV5 Pegmatite (Figure 1). Drilling continues to return wide

and well -mineralized intercepts at these depths , highlighted herein by drill hole CV22- 066 with 113.4 m at

1.61% Li2O (162.1 m to 275.5 m), including 38.0 m at 2.17% Li2O and 28.6 m at 2.31% Li2O. Additionally, drill

hole CV22-066 contains twenty (20) individual samples over 3.00% Li2O including two (2) adjacent samples grading

>6% Li 2O, averaging 2.0 m at 6.41% Li 2O, which contains a single spodumene crystal of approximately 1.8 m

(Figures 2, and 3). This is the largest spodumene crystal discovered to date in drill core at the Property and was first

reported in news release dated September 19, 2022.

The high-grade pegmatite in drill hole CV22-066 is interpreted to continue to surface as evidenced by CV22-063 with

39.9 m at 1.30% Li2O (69.9 m to 109.8 m), including 18.0 m at 2.28% Li2O, returned at shallow depths (Figure 1).

The pegmatite remains open at depth at this location with CV 22-069 returning 45.3 m of spodumene pegmatite at

depth below CV22-066 – assays remaining to be reported.

Additionally, drill hole CV22 -062 returned 60.0 m at 1.52% Li 2O (25.3 m to 85.3 m), including 18.0 m at

2.16% Li2O, at shallow depths proximal to the CV5 Pegmatite outcrop (Figure 4). These high grades continue at

depth below CV22- 062 with drillhole CV22 -064 returning 42.2 m at 1.52% Li2O (77.4 m to 119.5 m), 17.8 m at

2.53% Li2O (160.5 m to 178.3 m), 29.1 m at 1.21% Li2O (183.4 m to 212.5 m), and 10.9 m at 1.18% Li2O (220.2 m

to 231.1 m) . Drill hole CV22 -059 continued to demonstrate strong grades and wide intersections below the CV5

Pegmatite outcrop at moderate depths with 119.1 m at 0.89% Li 2O (57.3 m to 176.4 m), including 19.0 m at

2.05% Li2O and 15.0 m at 1.72% Li2O (304.9 m 319.9) (Figure 1).

Strong grades of tantalum continue to be returned from drilling at the CV5 Pegmatite with individual one (1) metre

samples grading >1,000 ppm Ta 2O5 returned from six (6) of the twelve (12) drill holes reported herein – CV22-055,

062, 063, 064, 065, and 066 – with a sample high of 3,293 ppm Ta2O5 returned from CV22-055. High-grade lithium-

tantalum intervals include 18.0 m at 2.16% Li2O and 316 ppm Ta 2O5 (CV22-062) and 42.2 m at 1.52% Li2O and

300 ppm Ta2O5 (CV22-064). The prevalence of tantalum is widespread at the CV5 Pegmatite with its zonation to be

more clearly defined upon receipt of the remaining 2022 drill core assays. Tantalum continues to be a secondary

commodity of strong interest at Corvette and recovery into a marketable concentrate will continue to be explored as

flowsheet studies are advanced.

The 2022 drill campaign at Corvette has significantly expanded lithium mineralization at the CV5 Pegmatite. The

drilling to date has largely been completed at approximately 100 m spacing (down to ~50 m in some places) with the

principal spodumene pegmatite body (CV5) , flanked by several secondary lenses, currently traced by drilling

over a distance of at least 2,200 m, remaining open along strike at both ends and to depth along most of its

length.

To date, the Company has completed ninety-five (95) NQ core size drill holes, totalling 27,470 m, at targets along the

CV Lithium Trend – eighty (80) drill holes totalling 24,709 m at the CV5 Pegmatite and proximal lenses , fourteen

(14) drill holes totalling 2,647 m at the CV13 Pegmatite cluster, and one (1) drill hole totalling 114 m at the CV12

Pegmatite cluster. For the drill holes reported herein, c ore assays for pegmatite intervals greater than two ( 2) m are

presented in Table 1 and drill hole locations in Figure 1. Drill hole coordinates and other attributes are available in

Table 1 and the Company’s website, which also lists assay results from prior drill holes. Core assay results for thirty-

eight (38) drill holes remain to be reported – twenty-four (24) at the CV5 Pegmatite cluster and fourteen (14) at the

CV13 pegmatite cluster.

2023 Exploration and Development Program

The Company is currently planning to re-commence drilling at the CV5 Pegmatite in January, with three (3) drill rigs

currently on site, and will increase to five (5) drill rigs in February. The primary objectives of the drill program are to

further delineate the extent of the CV5 Pegmatite, as well as infill drill to improve the geological model to achieve

indicated mineral resource confidence to support a subsequent Prefeasibility Study. Permits have been received and

construction underway for a n ~19.3 km winter road extending south from the Trans -Taiga all- season road to the

primary drill area at the CV5 Pegmatite , which will reduce transportation costs and improve access to the Property

over the winter portion of the 2023 exploration campaign.

BBA Inc. (“BBA”), a multi -disciplinary engineering and project development group, has been retained to complete

an inaugural mineral resource estimate at the CV5 Pegmatite – anticipated to be delivered in the first half of 2023 –

as well as carry -out development studies at the Property as it advances towards Prefeasibility. These studies include

site environmental, hydrogeological model, pit design, infrastructure layout, and tailings management. BBA has

significant experience in lithium pegmatite development studies in addition to their work at active mine-sites globally.

The Company will provide further details on the 2023 exploration and development programs in the new year, which

is anticipated to include significant resource delineation drilling, multi-disciplinary desktop and field studies in support

of advancing through Prefeasibility, and various lithium pegmatite surface exploration programs. Although at least

six (6) distinct lithium pegmatite clusters have been disc overed on the Property to date, there remains more than 20

km of trend yet to be evaluated for lithium pegmatite. Further, only three (3) of these lithium clusters have been drill

tested – CV5 (80 holes), CV13 (14 holes), and CV12 (1 hole).
