Reported Core Assays from 2022 Drilling at the Corvette Property,

Quebec

Vancouver, BC, Canada

Highlights

• Strong lithium and tantalum mineralization confirmed in first series of core sample assays received

for drill holes CV22-015, 016, 018, and 019, including

o 1.17% Li2O and 111 ppm Ta2O5 over 33.8 m within a wider zone of 0.80% Li2O and 118 ppm

Ta2O5 over 95.8 m (CV22-019)

• Core assays confirm the lithium-tantalum mineralization extends approximately 250 m along trend to

the northeast from drill hole CF21-002, and continues down-dip

o Lithium mineralization has been traced through drilling over a strike length of approximately

900 metres within the 2.0 + km long core area of the pegmatite trend, to a vertical depth of

approximately 155 m

o Mineralization remains open along trend and down-dip

• Core assays for additional sixteen (16) drill holes from the winter program remain to be reported

May 17 2022 – Patriot Battery Metals Inc. (the “Company” or “Patriot”) (CSE: PMET) (OTCQB: PMETF )

(FSE: R9GA) is pleased to announce the first series of analytical results for dr illing completed this winter/spring at

the Company’s wholly owned Corvette Property (the “Property”). The Property is located proximal to the regional

and all-weather Trans-Taiga Road and powerline infrastructure, within the James Bay Region of Quebec.

Assays are announced herein for drill holes CV22-015, 016, 018, and 019, which were designed to test the northeastern

and down-dip extension of the lithium-tantalum mineralized zone at the CV5 Pegmatite. All four holes were collared

over lake ice at an orientation of 158°/45°, with end -of-hole depths ranging from 149.9 m to 252.1 m , and each

returning strong grades of lithium and tantalum. A summary of lithium (and tantalum) intercepts for the four (4) drill

holes (CV22-15, 016, 018, and 019) are presented in Table 1 and Figure 2, and core photos of mineralized intercepts

in Figures 3, 4, and 5. Drill hole locations for holes completed as part of the winter program are in Figure 1.

President, CEO, and Director Blair Way comments, “ We are very excited to announce assays for the first series of

holes of our twenty-hole winter/spring drill program and look forward to announcing further assay results as they are

received from the lab in the coming weeks. These independent assays, confirming lithium and tantalum mineralization

within the CV5-1 Corridor, validate the Company’s decision to add a third rig to our summer drill program , which

was made after geologists in the field identified spodumene crystals in the pegmatite intercepts as part of initial core

logging. After drilling only 5,100 met res, Patriot has established lithium and tantalum mineralization across an

approximate 900 m strike length, which remains open at both ends and down- dip. The Patriot team is excited to

commence the 15,000 metre summer/fall drill program in June and further delineate this discovery . Additionally,

Patriot has identified multiple other spodumene pegmatites across the Property and we look forward to exploring

these further, as well as the remainder of the more than 50 km long CV Lithium Trend the Company controls, as part

of our summer 2022 program.”

Drill hole CV22-015 was the first drill hole completed in 2022 and collared as a step-out, approximately 140 m along

trend, of drill hole CF21-002 completed in 2021 at the CV5 Pegmatite. The hole (CV22-015) encountered pegmatite

at a shallow depth of 27.1 m to 75.1 m, with mineralization interfingering throughout the interval, including

1.22% Li2O over 6.8 m, 1.14% Li2O over 4.9 m, and 0.99% Li2O over 4.5 m. The intercepts were also accompanied

by consistently strong tantalum grades of 113 ppm, 96 ppm, and 105 ppm Ta2O5, respectively.

Drill hole CV22-018 was collared 100 m along trend of CV22-015 and returned a mineralized pegmatite intercept of

1.01% Li2O and 100 ppm Ta2O over 25.8 m starting at 55.0 m depth. The intersections in drill holes CV22-015 and

018 confirms that lithium-tantalum mineralization continues within the CV5 P egmatite body to the northeast under

the shallow lake.

Drill holes CV22-016 and 019 were completed as step-backs to CV22-015 and 018, respectively, and were designed

to test the mineralized zone at depth. Both holes returned strong lithium grades over broad intervals including

0.91% Li2O over 29.0 m within a wider zone of 0.8 5% Li2O over 56. 6 m (CV22-016), and 1.17% Li2O over

33.8 m within a wider zone of 0.80% Li 2O over 95.8 m ( CV22-019). The intercepts confirm that mineraliz ation

continues down dip to at least 155 m vertical depth and, further, indicates that the mineralized zone is widening at

depth, as is the pegmatite width, at this location along the trend. Strong tantalum mineralization is also present in both

CV22-016 and 019, with each having multiple samples over 5 00 ppm Ta 2O5, to a peak of 735 ppm and 758 ppm

Ta2O5, respectively.

As outlined in news release dated April 21 st, 202 2, geological 3D modeling of the drill holes completed to date

indicates that pegmatite continues across the lake from CV5 towards CV1 – a strike length of at least 1,400 m –

and that the pegmatite body is widening at depth. The pegmatite body remains open to the southwest, the northeast,

and at depth, with a significant portion of the overall corridor of focus – containing the CV6, CV5, CV11, CV2, CV1,

CV4, and CV7 pegmatite outcrops – remaining to be drill tested (Figure 1). To date, the main pegmatite body has

been traced to a vertical depth of a least 180 m (CV22- 030) and additional pegmatite encountered down to a vertical

depth of approximately 265 m – ending in spodumene pegmatite , to be further tested in the drill program scheduled

to commence in June 2022 (CV22-034).

As reported herein, lithium mineralization has been traced by drilling over at least a 900 m strike length and down dip

to at least 155 m vertical depth. To date, drill core sample analytical results have been reported for four (4) drill holes

(CV22-015, 016, 018, and 019) with res ults pending for an additional sixteen ( 16) drill holes completed over the

winter/spring program (4,345 m over 20 drill holes). The Company is using SGS Canada (Lakefield, ON, and Burnaby,

BC, facilities) as their primary analytical lab with all samples from the program having arrived at the lab.

The Company is poised to continue its fully funded 2022 drill campaign June 1st, with an additional 15,000 m of NQ

coring planned over the summer/fall period. This drilling will focus on continued land-based infill and step-out holes

around CV5- 6 and CV1- 2, as well as testing new regional targets (see news release dated March 8 th, 2022). The

Company has secured a third drill rig for June/July, as well as a barge to allow for continued delineation of the

mineralized pegmatite beneath the shallow lake between the CV5 and CV1 pegmatites. The addition of the third rig

will also enable increased coring production and drill exploration of spodumene pegmatite elsewhere at the Property.

The Company notes that it has developed a COVID Management Plan for the program and will carry out its field

programs while adhering to all federal, provincial, and regional restrictions in place due to the COVID -19 pandemic.

Mineral exploration has been recognized as an essential service in Canada and the Province of Quebec.

Quality Assurance / Quality Control (QAQC)

A Quality Assurance / Quality Control protocol fol lowing industry best practices was incorporated into the program

and included systematic insertion of quartz blanks and certified reference materials into sample batches, as well as

collection of quarter -core duplicates, at a rate of approximately 5%. Additionally, analysis of pulp-split and course-

split sample duplicates were completed to assess analytical precision at different stages of the l aboratory preparation

process, and external (secondary) laboratory pulp- split duplicates were prepared at the prim ary lab for subsequent

check analysis and validation.

All core samples collected were shipped to SGS Canada’s laboratory in Lakefield, ON, for standard sample

preparation (code PRP89) which includes drying at 105°C, crush to 75% 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 (code GE_ICM91A50).
