Power Metals' Rare Find: Cesium

Corporate Updates

Power Metals' Rare Find: Cesium

VANCOUVER, BC

,

Oct. 19, 2022

/CNW/ -

Power Metals Corp.

("

Power Metals

" or the

"

Company

") (TSXV: PWM) (FRANKFURT: OAA1) (OTCQB: PWRMF) is pleased to comment and

provide information to its recent banner press release on

Oct. 13

th

, 2022. Power Metals is

extremely thrilled with the recently announced high-grade cesium discovery in the West Joe Dyke at

the Company's 100% owned Case Lake Property in

Cochrane

, Ontario. The cesium (Cs)

mineralization is enclosed in lithium (Li) and tantalum (Ta) mineralization to make West Joe a three-

commodity deposit. The ongoing 2022 drill program intersected 24.07% Cs

2

O over

1.0 m

and

7.65% Cs

2

O and 1.45% Li

2

O over

7.09 m

, additional the lithium mineralization is the highest found at

Case Lake with 4.75% Li

2

O, 2.71% Cs

2

O and 396 ppm Ta over

2.0 m

in white to pink coarse-

grained spodumene.

In January of this year, world-leader Sinomine Resource Group ("Sinomine") joined Power Metals

Corp. with a sizable investment after Power Metals' initial discovery of cesium during the 2018-2019

drilling campaign (PWM press release dated

November 13

, 2018). Sinomine currently owns two of

the three occurrences of cesium that have been commercially mined, making them the ideal partner

for Power Metals Corp.

Johnathan More

, Chairman & CEO of Power Metals stated, "Sinomine's involvement with Power

Metals is very strategic to both parties. There is a direct railway line from the town of

Cochrane

to

the Tanco mine. Most importantly Sinomine has been involved in all areas of past cesium production

around the world. Additionally, we are still waiting for several more assays currently at the lab and

will be releasing them as soon as they are available."

The West Joe pollucite zone has Cs grades similar to that of Sinclair cesium mine,

Australia

now

held by Essential Metals Limited (ASX: ESS). In addition to the Cs grade, West Joe has the

advantages that the pollucite has shallow depths of less than

50 m

below surface and road access

to make it easy for future extraction. Another advantage of West Joe is that it has three economic

commodities in the same zone: lithium, cesium and tantalum. Canadian,

Ontario

and

United States

governments have labelled all three commodities as critical metals.

What is Cesium?

Cesium is a chemical element with the symbol Cs and atomic number in the periodic table. The ore

mineral of Cesium is pollucite, a Cs aluminum silicate mineral.

Why is Cesium so rare?

Pollucite crystallizes in highly fractionated lithium pegmatite dykes. Very few pegmatites are evolved

enough to contain crystals of pollucite. There are only five recorded occurrences of pollucite in

Ontario

of which Power Metals owns three occurrences: West Joe Dyke on Case Lake Property,

Marko's pegmatite on Paterson Lake Property and Tot Lake pegmatite on Gullwing-Tot Lakes

Property.

Globally, there are three occurrences for cesium that have been commercially mined: Tanco

pegmatite mine,

Manitoba, Canada

, Bikita pegmatite mine,

Zimbabwe

and Sinclair mine,

Australia

.

The Tanco underground mine has been in operation since the late 1960's. Tanco is mined for

tantalum (Ta) ore concentrates, pyroceramic spodumene (Li), pollucite (Cs) and rubidium (Rb). The

pollucite is processed on site to produce cesium formate fluid as a heavy mud for offshore oil drilling

in the North Sea. Sinomine Resources Group bought the Tanco mine from Cabot Corporation in

2019 including the underground room and pillar mine, spodumene concentrator mill and cesium

chemical processing facility and the mine which employs about 100 workers.

The Bikita mine, Masvingo Province,

Zimbabwe

has been in operation since 1950. Its main products

are technical grade petalite concentrates (Li ore) used in glass and ceramics and pollucite (Cs ore).

Sinomine Resources Group bought the Bikita open pit mine in

January 2022

. Sinomine plans to

produce spodumene, to build a plant and expand the existing mining operations at Bikita.

The Sinclair mine,

Western Australia

was drilled by Pioneer Resources Limited (ASX: PIO)

("Pioneer") in 2016 for petalite (Li ore) and pollucite was discovered and confirmed in

November

2016

(Pioneer Resources press release dated

Nov. 14

, 2016). Pioneer announced that it entered

into an offtake agreement with Cabot Corporation ("Cabot") to buy 100% of the cesium ore

extracted from

Sinclair Zone

(press release dated

June 20, 2018

). Sinclair mine was

Australia's

first

ever commercial cesium producer. Pioneer announced on

22 January 2019

that approximately

19,000 tonnes of pollucite-bearing rock with an average grade of 9.1% Cs

2

O has been mined and

crushed, to be sold within a specification under the Offtake and Loan arrangement in place with

Cabot. Cabot received the first shipment of cesium in

April 2019

at the Tanco mine (press release

Apr. 17, 2019

). Pioneer entered into a separate sales agreement and off-take with Sinomine

Specialty Fluids for 7,300 tonnes of ore with an estimated average grade of 4.5% Cs

2

O consisting

of pollucite, lepidolite and quartz (press release

March 16, 2020

).

What is Cesium used for?

The primary use of the cesium mined at Tanco,

Manitoba

is for cesium formate brines used for high

pressure, high temperature well drilling for oil and gas. Cesium bromide is used in infrared detectors,

optics, photoelectric cells, scintillation counters and spectrometers (United States Geological Survey

Mineral Commodity Summaries 2022). Cesium isotopes are used in atomic resonance frequency in

standard atomic clocks which play a vital role in aircraft guidance systems, global positioning

satellites and internet and cellular telephone transmissions (USGS Mineral Commodity Summaries

2022).

What is the price of Cesium?

Pioneer sold 19,000 tonnes of pollucite ore with an average grade of 9.1 % Cs

2

O from the Sinclair

mine for an expected total of

A$17.4 million

between Jan and

Nov. 2019

, excluding the sales of the

low-grade material (press release dated

Sep. 11, 2019

).

Pioneer sold 7,300 tonnes of pollucite ore with an estimated average grade of 4.5 % Cs

2

O for

approximately

$1.2 million

from its Sinclair mine (press release dated

March 16, 2020

).

Dr.

Julie Selway

, VP of Exploration commented, "Power Metals is excited to have such a rare critical

mineral on the Case Lake Property and the ore grade lithium and tantalum at shallow depths is an

extra bonus."

Quality Control

The drill core was sampled so that

1 m

of the Case Batholith tonalite host rock was sampled

followed by

1 m

long samples of the pegmatite dyke and

1 m

of the Case Batholith. The sampling

followed lithology boundaries so that only one lithology unit is within a sample, except for the < 20

cm pegmatite veins in tonalite which were merged into one sample. The drill core samples were

delivered to SGS preparation lab in

Cochrane

by Power Metals' geologists. The core was prepared

at SGS Garson and analyzed at SGS

Burnaby, British Columbia

which has ISO 17025 certification.

Every 20 samples included one external quartz blank, one external lithium standard and one core

duplicate. The ore grade Li

2

O% was prepared by sodium peroxide fusion with analysis by ICP-OES

with a detection limit of 0.002 % Li

2

O. A Quality Control review of the standards, blanks and core

duplicates indicated that they all passed. The ore grade Cs

2

O% for > 10000 ppm Cs was prepared

by alkaline metal digestion with analysis by FAAS with a detection limit of 0.002 % Cs. Ore grade

cesium was analyzed by SGS

Lakefield, Ontario

which also has ISO 17025 certification.

Case Lake Property

Case Lake Property is located 80 km east of

Cochrane

, northeastern

Ontario

close to the

Ontario

-

Quebec

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

Pliny,

Abbotsford

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

km in size with 14 identified tonalite domes. The Case Lake pegmatite swarm consists of six

spodumene dykes: North, Main, South, East and Northeast Dykes on the Henry Dome and the West

Joe Dyke on a new tonalite dome. 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

.
