WINTER 2024 EXPLORATION DRILL PROGRAM

Exploration drilling for the winter 2024 program is now completed at Case Lake with 3,907 meters

drilled for thirty-eight (38) diamond drill holes completed of the planned 4,000-meter program.

Major

Drilling

demobilized the rig and team last week and all samples have been submitted to the

laboratories for analysis. The Company has drilled thirty-two (32) exploration drill holes at West Joe

focusing on defining and expanding the current world-class high-grade mineralization potential that is

represented at the West Joe deposit (Figure 1 to 3 and Table 1). Positive lithium assay results

were received from the five (5) exploration drill holes at Main Zone has confirmed the continued

presence of high-grade Lithium – Cesium – Tantalum (LCT) mineralization in stacked pegmatite

systems (Figures 4 to 6 and Table 1).

Haydn Daxter, Power Metals CEO commented "I am very pleased to see the first round of assay

results from our exploration drilling program, these confirm our Case Lake property continues to

deliver at a high level with results outside of the known mineralization envelope. We are incredibly

buoyant on the cesium and spodumene potential displayed at West Joe from the current drilling

and look forward to seeing the remaining assay results. Globally cesium is a critical mineral that

has only produced three (3) known mineable resources to date, and the Company is well

positioned to unlock the full potential at West Joe. At the same time the Main Zone continues to

display very encouraging lithium mineralization in stacked pegmatites with consistent grades and

widths for the Company".

WEST JOE

The West Joe deposit is a unique, highly fractionated LCT pegmatite system that contains world-

class high-grade cesium (Cs

2

O) mineralization hosted in pollucite (Figure 1). It is characterized by

two stacked pegmatites that are up to 9 meters thick and contain high grade Lithium – Cesium –

Tantalum mineralization, extending for 100 meters along strike and open down plunge. The deposit

was discovered by Power Metals in 2018 with high grade cesium up to 24% reported during drill

programs completed in 2018 and 2022.

Figure 1 – West Joe plan View Map Displaying Collar Location from the 2024 Drilling Program

(CNW Group/Power Metals Corp.)

High-grade cesium mineralization at West Joe occurs at the far west end of a 10 km mineralization

trend at Case Lake that extends from Dome 9 to the far northeast through to West Joe in the west.

The 2024 drilling at West Joe (holes PWM-24-171 to PWM-24-202) is targeting high grade cesium

in pollucite, spodumene, and tantalite-columbite mineralization that occurs in and around contact

between Case Lake Batholith and metasedimentary units. Several step out exploration holes were

drilled to test exploration targets along strike and down dip of the West Joe deposit in line with the

current geological model.

Figure 2 - Cross section of PWM24-171 with results from West Joe drilling from the Company’s

2024 program, along with previously released results from 2022 (CNW Group/Power Metals Corp.)

The first five exploration drill holes as reported in this announcement highlight the continuation of a

world-class, high-grade cesium zone at West Joe with broad lower grade cesium mineralization

along with narrow high grade cesium mineralization of close to pure pollucite. All holes have

intercepted high-grade cesium mineralization in pollucite, and at a very shallow depth that will assist

in growing the known mineralized zone to near surface projection.

high-grade zone cesium zone, we defined a 2.0-meter interval of

15.05% Cs

O

and a meter of

18.13% Cs

(Figure 3 and Table 1). Cesium grades this high have only been reported to date in

the three known global deposits, Bakita*, Sinclair*, and Tanco. The consistent mineralization from

the current and historical drilling at West Joe adds further weight to this developing into a world

class deposit.

*These projects are currently not in operation.

CASE LAKE MAIN

LCT pegmatite mineralization at Case Main is represented as a stacked pegmatite system that is

part of three main dykes, historically referred as South, Main, and North dykes (Figure 4). The LCT

pegmatite system at Case Main is characterized by high-grade Lithium – Tantalum ± Cesium

mineralization that is up to 35 meters thick and extends for more than 400 meters along strike.

Mineralization continues to 100 meters vertical depth and remains open down plunge to the west and

along strike to the east.

to the north. The mineralization at Case Main and throughout Case Lake property

displays distinct zonation of spodumene, tantalite-columbite, and pollucite, characteristics of highly

fractionated LCT pegmatite systems. The North and Main dykes at Case Main are characterized by

lithium-rich coarse-grained 2 – 25 cm spodumene mineralization that makes up to 10 to 30 % of the

dykes, whereas the South dyke and several subordinate dykes are characterized by lower-grade

lithium and ore-grade tantalum mineralization.

Drilling conducted at Case Main during the 2024 program (PWM-24-164 to PWM-24-170) delineated

shallow high-grade lithium and tantalum mineralization characterized by coarse-graded spodumene in

the Main and North dykes with up to

13.30m

@ 1.84% Li

O

, PWM-24-167. In addition to this drilling

intercepted the presence of several lower grade pegmatites with ore-grade tantalum in the South

dyke and sporadic subordinate dykes that confirms the exploration potential for additional

mineralization occurring in these dykes (Figure 5-6 and Table 1).

Johnathan More

, Chairman of Power Metals commented "We are extremely pleased to see the

first round of assays back from the laboratory from our winter 2024 drill program at Case Lake that

further confirms high-grade Cesium and Lithium mineralization at West Joe with its world-class

potential and Main Zone producing consistent results. We look forward to releasing additional

results as we begin our upcoming summer field activities and phase II drilling."

SPRING SHUTDOWN

The Company completed drilling and completely demobilized from Case Lake as of the 17

th

of May

and in line with respecting the annual hunting period and practices conducted each spring by the

traditional landowners. The Company has commenced a review on the drilling data from Phase I as

we prepare to commence planning for Phase II drilling along with development of the current

geological model and our summer field activities.

Prior to the shutdown the Company has also completed a series of metallurgical drill holes at West

Joe in preparation for our next stages of exploration and project development across the Case Lake

property.

Sampling and QAQC Procedures

Samples were taken across every pegmatite and 1.5 meter into the barren host rock on either side

of dykes. Sample lengths were around 1-metre NQ core diameter (48 mm), though individual sample

length was determined based on internal zoning of the dykes and the locations of their contacts. The

sampled core was cut in half with one half being sent for analysis and the other half remaining in the

box for reference. All core is stored at Power Metals core storage facility in

Cochrane, Ontario

.

Each sample was put into its own plastic sample bag with a sample tag and closed with zip ties.

About 15% of the samples submitted to Activation Laboratories Ltd. ("Actlabs") and SGS Canada

("SGS") for analysis were QAQC samples that were inserted into the sample stream and consist of

a high- and low-grade lithium, Tantalum, and Cesium standards, blank material, and duplicates.

Samples were dropped at either Actlabs Timmins or SGS Cochrane, in

Ontario

. Samples submitted

to Actlabs were prepped, crushed and pulverized in

Timmins

and were subsequently sent to Actlabs

geochemistry laboratory in

Ancaster, Ontario

for multi element analysis using sodium peroxide fusion

ICP-OES/ICP-MS and borate fusion ICP-MS. Samples submitted to SGS were prepped, crushed,

and pulverized in

Sudbury

and were subsequently sent to SGS Burnaby and SGS Lakefield for multi

element analysis using sodium peroxide fusion ICP-AES/ICP-MS and borate fusion XRF. All cesium

results above 1% were analyzed using 4-Acid digest AAS at SGS Lakefield.

Actlabs and SGS Canada are independent of the Company.

Case Lake Property

The Case Lake Property is located 80 km east of

Cochrane

, northeastern

Ontario

close to the

Ontario

-

Quebec

border. The Property consists of 585 cell claims in Steele, Case, Scapa, Pliny,

Abbotsford

and Challies townships, Larder Lake Mining Division. The Property is 10km by 9.5km in

size with 14 granitic domes. The Case Lake pegmatite swarm consists of six spodumene dykes

known as the North, Main, South, East and Northeast dykes on the Henry Dome, and the West Joe

dyke on a new dome, collectively forming mineralization trend that extends for approximately 10km

(Figure 7).

Power Metals have completed several exploration campaigns that have led to the discovery and

expansion of new and historic spodumene bearing LCT pegmatites at Case Lake. The Company has

drilled a total of 19,607 meters of core between 2017 and 2024 at the Property. The Case Lake

Property is owned 100% by Power Metals Corp. A National Instrument 43-101 Technical Report has

been prepared on Case Lake Property and filed on

July 18, 2017

.

Pelletier Property

The Pelletier Property is located 50km south of

Hearst

, northeastern

Ontario

close to a network of

forestry roads. The Property consists of 337 mineral claims that account for a total of 7000 hectares

in Franz, Roche, Scholfield, and Talbot townships in the Porcupine mining division. The Pelletier

Project is characterized by LCT prospective S-type pegmatitic granites intruding into

metasedimentary and amphibolite of the Quetico at or near Archean terrane boundary between the

Quetico and

Wawa

sub-provinces (Figure 7).

Decelles Property

The Decelles Property contains 669 claims, covering 38,404 hectares of LCT prospective ground

near the mining centers of Val-dÓr and

Rouyn-Noranda

, approximately 600km from

Montreal

. Power

Metals acquired the Decelles and Mazerac properties from Winsome Resources in 2023 in a deal

that allowed Winsome to increase its stake to 19.59% (Refer to press release announced on

August 24, 2023

). The geology of Decelles property is part of the Archean Pontiac sub-province

where S-type LCT prospective, pegmatite bearing, granitic Decelles Batholith intrudes into

metasedimentary units of the Pontiac Group. Spodumene and Beryl bearing pegmatites have been

reported historically within the

Pontiac

sub-province in association with S-type garnet-muscovite

granite. The Decelles property is adjacent to Vision Lithium's Cadillac property where discovery of

high-grade lithium pegmatites was reported in 2022 (Figure 7).

Mazerac Property

The Mazerac Property is located approximately 30 km east of Power Metals' Decelles property near

well-established mining camps in the Abitibi region of

Canada

and is accessible by network of

mining-grade forestry roads. The Mazerac property contains 259 claims that cover 14,700 hectares

of LCT prospective ground near the mining center of Val-dÓr and

Rouyn-Noranda

. The regional

geology of Mazerac is similar to Decelles where S-type LCT prospective, pegmatite bearing,

granites of Decelles Batholith intrude into metasedimentary units of the Pontiac Group. Spodumene

and Beryl bearing pegmatites have been reported historically within the

Pontiac

sub-province in

association with S-type garnet-muscovite granite (Figure 7).

Pollucite and Cesium

Pollucite is a rare mineral that hosts high grade cesium and is associated with highly fractionated,

compact, and rare element pegmatites. The main source of cesium known globally is pollucite

(Cs,Na)

(Al
