Patriot Drills 56.6 m at 1.37% Li2O in Step-Out Hole and Completes

Final Hole of 2023 Program at the CV5 Pegmatite, Quebec, Canada

December 17, 2023 – Vancouver, BC, Canada December 18, 2023 – Sydney, Australia

Highlights

• Patriot continues to intersect well-mineralised zones in step -out drilling at the CV5

Pegmatite, with highlights:

o 56.6 m at 1.37% Li2O and 9.9 m at 3.58% Li2O (CV23-231).

o 50.1 m at 1.17% Li2O, 38.0 m at 1.44% Li2O, and 17.2 m at 2.20% Li2O

(CV23-223).

o 48.4 m at 1.21% Li2O, including 11.0 m at 3.42% Li2O (CV23-211).

o 29.2 m at 1.35% Li2O, including 8.4 m at 3.50% Li2O (CV23-240).

o 25.6 m at 1.98% Li2O and 33.4 m at 0.80% Li2O (CV23-222).

• Patriot continues to intersect well-mineralised zones in step -out drilling at the CV13

Pegmatite, with highlights:

o 19.2 m at 1.74% Li2O (CV23-215).

o 14.8 m at 1.36% Li2O (CV23-210).

• A total of 177 holes, for approximately 45,700 m, ha s been completed over the summer -

fall program. Assay results for 27 holes are reported herein. Assays remain to be reported

for more than 125 drill holes, including ~1.5 km of prospective pegmatite trend across

the CV5 and CV13 pegmatites.

o The Company is currently working to process a backlog of core, due to wildfires

and prioritization of drilling staff in accommodation. Core processing is continuing

at site and is expected to continue through to the holidays to clear the remaining

backlog.

o Going forward the Company will only report pegmatite drill intercepts at the same

time as the respective core assays are announced, in compliance with applicable

ASX and TSX-V rules. The change is intended to allow for reporting of results in

the most appropriate manner available between the ASX and TSX regulatory

regimes.

• The CV5 Spodumene Pegmatite has been traced to a 4.35 km strike length, which

remains open along strike and at depth ( see news release dated September 24, 2023 ) –

drill results for an additional 0.25 km of prospective strike length remain to be reported.

• The CV13 Spodumene Pegmatite has been traced to a ~1.1 km strike length, which

remains open along strike and at depth (see news release dated October 18, 2023) – drill

results for an additional ~1.2 km of prospective strike length remain to be reported.

• The CV9 Spodumene Pegmatite has been traced to a 0.45 km strike length following

initial drill testing , which remains open along strike and at depth (see news released

dated November 22, 2023).

• Multiple spodumene pegmatite outcrop clusters remaining to be drill tested – CV4, CV8,

CV10, and CV12 (only 1 shallow hole completed to date).

Blair Way , Company President, CEO, and Director , comments: “ It is hard to understate the

success of the 2023 drill campaign, including our recently completed summer-fall program. In

addition to underpinning a maiden mineral resource estimate mid year, which established CV5 as

a world class deposit and one of the largest lithium pegmatites globally, we have extended the

strike length of CV5 to 4.35 km with drill results over additional prospective strike remaining to

be reported. Further, drilling this summer-fall at CV13 has confirmed continuous pegmatite of at

least 1.1 km in strike length with drill results for an additional 1.2 km of prospective strike

remaining to be reported, and initial drill testing at CV9 has outlined a potentially large and fertile

pegmatite over at least 450 m of strike length . The 2023 program has firmly demonstrated the

world class scale of the system at Corvette, and is poised for continued growth over the next few

months as additional assays from the program are reported.”

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

(OTCQX: PMETF) (FSE: R9GA) is pleased to announce further drill results , as well as

completion of the final hole of its 2023 drill campaign at the Corvette Property with core

processing continuing at site. The Corvette Property (the “Property” or “Project”), wholly owned

by the Company, is located in the Eeyou Istchee James Bay region of Quebec. The 2023 drill

campaign included holes completed at the CV5, CV13, and CV9 pegmatites. The CV5 Spodumene

Pegmatite, with a maiden mineral resource estimate of 109.2 Mt at 1.42% Li 2O inferred 1, is

situated approximately 13.5 km south of the regional and all‑weather Trans -Taiga Road and

powerline infrastructure. The CV13 and CV9 spodumene pegmatite s are located approximately

3 km west-southwest and 14 km west of CV5, respectively (Figure 1).

A total of 266 holes, for approximately 78,100 m of coring, have been completed over the 2023

drill campaign. Of this, 177 holes, totalling approximately 45,700 m, have been completed during

the summer-fall program – 82 holes (~26,600 m) at CV5, 74 holes (~14,900 m) at CV13, 18 holes

(~4,050 m) at CV9, and 3 holes (~150 m) at the KM-270 camp. Collectively, to date, the Company

has now completed over 350 drill holes, totalling approximately 105,500 m, targeting lithium

pegmatite across the Property.

The Company continues to process drill core from the 2023 program on site and is expected to

have core samples from the final holes into the lab early in the new year. Going forward the

Company will only report pegmatite drill intercepts at the same time as the respective core assays

are announced, in compliance with applicable ASX and TSX -V rules. The change is intended to

allow for reporting of results in the most appropriate manner available between the ASX and TSX

regulatory regimes.

Drill core sample a ssay results for 2 7 holes are reported herein. Core sample assays for more

than 125 holes completed over the 2023 summer fall drill program remain to be announced.

CV5 Pegmatite

New drill results reported herein continue to demonstrate that the CV5 Spodumene Pegmatite

remains well mineralized over its previously announced western extension (see news release dated

September 24, 2023 ), and outside of the June 2023 mineral resource estimate block model (see

news released dated July 30, 2023). Results are presented in Table 1 and include:

• 56.6 m at 1.37% Li2O and 9.9 m at 3.58% Li2O (CV23-231).

• 50.1 m at 1.17% Li2O, 38.0 m at 1.44% Li2O, and 17.2 m at 2.20% Li2O (CV23-223).

• 48.4 m at 1.21% Li2O, including 11.0 m at 3.42% Li2O (CV23-211).

• 29.2 m at 1.35% Li2O, including 8.4 m at 3.50% Li2O (CV23-240).

• 25.6 m at 1.98% Li2O and 33.4 m at 0.80% Li2O (CV23-222).

Figure 2: Simplified geological cross-sections over the recently defined western extension at CV5.

Very strong grades over material widths are present over the western extension at CV5, including

at least four (4) intervals of 5+ m at 3. 4+% Li2O (drill holes CV23-208, 211, 231, and 240) in

assays reported to date. F urther drill delineation of the area is a high priority for the Company.

Geological cross-section interpretations for two fences of drill holes completed over the western

extension are presented in Figure 2.

Additionally, i nfill drilling at CV5 continues to return wide and well- mineralized spodumene

pegmatite intercepts. Results announced herein include 67.1 m at 1.56% Li2O, including 13.0 m

at 3.44% Li2O (CV23-241), and 63.0 m at 1.13% Li2O (CV23-230).

With the 2023 summer -fall drill program now completed, the Company has extended the CV5

Pegmatite to approximately 4.35 km total strike length and remains open (see news release

dated September 24, 2023 ) with drill results for an additional 0.25 km of prospective strike

length remaining to be reported ( Figure 3). The CV5 maiden mineral resource estimate

(109.2 Mt at 1.42% Li 2O, inferred1) includes only ~ 3.4 km of the current 4.35 km strike length,

thereby outlining significant and tangible potential for resource expansion. Already, the maiden

mineral resource estimate for CV5 denotes it as the largest lithium pegmatite deposit in the

Americas1 and is well positioned to become an important source of spodumene for the growing

battery-supply chain of North America.

Collectively, the 2023 summer-fall program has drill tested an additional 900 m of strike length

over the CV5 area with results reported for only 650 m of this. This drilling was completed in the

west as step-outs towards CV13, closing the gap remaining to be drill tested between the two

pegmatites to 2.9 km (Figure 4).

CV13 Pegmatite

At the CV13 Pegmatite, drill results continue to demonstrate a well- mineralized upper pegmatite

dyke of comparable widths to those reported in drill hole in 2022. Drill results announced herein

are presented in Table 2 and include:

• 19.2 m at 1.74% Li2O (CV23-215)

• 14.8 m at 1.36% Li2O (CV23-210)

• 11.2 m at 1.02% Li2O (CV23-235)

• 9.7 m at 1.07% Li2O (CV23-213)

The lower pegmatite dyke remains more variably mineralized compared to the upper dyke with

results including 10.0 m at 0.83% Li 2O (CV23-218). The Company will continue to strategically

test the lower pegmatite dyke for abrupt thickening (i.e., a blow-out) coincident with the presence

of spodumene mineralization.
