As with the Phase I ore sorting test work, the Company conducted X-ray Transmission (XRT) based
ore sorting technology to produce all metallurgical samples for Phase II, crushed and blended
forming a bulk metallurgical sample, that was subsequently divided into two sample subsets (+12-
25mm and +6-12mm) and a fines material (sub 6mm) based on size fraction of ore particles.
The primary and secondary XRT analysis utilised 254 kg of material from 67 drill core samples that
were crushed, screened at 6 to 25 mm, and sorted with two stages of XRT testing. The feed grade

METALLURGICAL HOLES:
Phase I and II metallurgical drilling consisted of 9 (nine) HQ (63.5mm) diamond drill holes at West
Joe. Drilling consisted of shallow targets to provide a consistent ore sorting and mineral separation
on the West Joe Project. Targeting high grade cesium oxide through to the Company's proposed
cut-off grades at the lower end of mineralization. Phase II ore sorting and the separation of cesium
oxide material from the metallurgical holes also included high-grade spodumene and tantalum (Table
5) which has the capacity to develop additional streams of income alongside the cesium oxide
production. Cesium oxide concentrate is currently with SGS Lakefield for analysis to produce
product grades.

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 (47.6 mm) and HQ (63.5 mm) core diameter,
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 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 SGS Cochrane, in
Ontario
. 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. Assay results for
products of ore sorting samples were analyzed at SGS Lakefield using sodium peroxide fusion ICP-
OES for Lithium, sodium peroxide fusion ICP-MS, and borate fusion XRF for Cesium.
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 586 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 1).
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 23,976 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
(Figure 1).
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 1).
Decelles Property
The Decelles Property contains 669 claims, covering 38,404 hectares of LCT prospective ground
near the mining centres 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 transaction remains subject to TSXV approval. 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 1).
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 centre 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 1)
