Power Metals Announces 13 Grab Samples with 3.36% to 4.43% Li2O from Marko's Pegmatite
Power Metals Announces 13 Grab Samples with 3.36% to
4.43% Li2O from Marko's Pegmatite

/CNW/ -
Power Metals Corp.
("
Power Metals Corp.
" or the "
Company
") (TSX
VENTURE:PWM)(FRANKFURT:OAA1)(OTC:PWRMF) is pleased to announce that 13 high-grade surface grab samples
collected along a
268 m
strike length of the Marko's pegmatite have 3.36 to 4.43 % Li
2
O indicating that they are
dominantly petalite (Figure 1). Marko's pegmatite is a petalite pegmatite on Paterson Lake Property, 60 km north of
Kenora
, northwestern
Ontario
. It is one of the top three pegmatites for Lithium and Tantalum mineralization in the
Separation Rapid Greenstone Belt and is drill ready. Multiple high-grade Lithium (Li) assays include:
3.36 to 4.43 % Li
2
O range for 13 samples
2.17 and 2.92 % Li
2
O, two samples (159314 and 159316, respectively)
1.57 % Li
2
O, sample 159218
These high-grade lithium samples were collected from three clusters over a
268 m
strike length (Table 1, Figure 2).
Power Metals geologists successfully located and completed a Trimble DGPS survey on 16 historic drill holes on Marko's
Pegmatite and on legacy corner claim posts (Table 2, Figure 3). Historically, there was some confusion as to the location
of the Marko's pegmatite. It was believed to be on our neighbour's Property, but our ground truthing and DGPS survey
clearly shows that Marko's Pegmatite is on Power Metals' Paterson Lake Property. Our geologists used metal detectors
to find the historic casing and were able to read the drill hole numbers on the aluminum tags near the collars. The Marko's
pegmatite is one of the top three pegmatites for Lithium and Tantalum mineralization in the Separation Rapid Greenstone
Belt. Champion Bear Resources Ltd. drilled 7 holes (SR-01 to 07) totaling
732 m
, 9 holes (SR-11 to 19) totaling
1085 m
in
2001 and 4 holes (SR-02-26 to 29) totaling
459 m
in 2002. For a total of 20 holes and
2276 m
all of which except for one
hole (SR-19) is on Power Metals' Paterson Lake Property.
Dr. Selway, VP of Exploration, stated "I am excited to confirm that Marko's pegmatite and North Marko's pegmatite
historic drill holes are on Power Metals Property thanks to the ground truthing by our geologists. The presence of Marko's
petalite pegmatite increases the lithium potential of the entire property significantly, as we have
268 m
strike length of
lithium mineralization. I am looking forward to a winter drill program on Marko's pegmatite once we receive permit
approval."
Locating Marko's pegmatite on Power Metals Paterson Lake Property has significantly increased the lithium economic
potential of the Property. Power Metals will benefit from the historic drilling that showed that there is both Lithium and
Tantalum mineralization at depth on the Marko's pegmatite. The lithium mineralization is not limited to just one pegmatite
dyke but two pegmatite dykes: Marko's pegmatite and North Marko's pegmatite as shown by historical drilling. Our grab
sampling has shown that the lithium mineralization in outcrop on surface has a strike length of
268 m
. Marko's pegmatite is
drill ready and Power Metals has applied for an exploration permit for drilling from MNDM on Paterson Lake Property.
At Marko's pegmatite, petalite is the dominant lithium ore mineral, but spodumene is also present in the dyke. Petalite
(LiAlSi
4
O
10
) is the high temperature lithium aluminosilicate whereas spodumene (LiAlSi
2
O
6
) is the low temperature/high
pressure lithium aluminosilicate. Both petalite and spodumene can be used to produce lithium carbonate and lithium
hydroxide for lithium batteries.
In addition to high-grade Lithium mineralization, the Marko's pegmatite also has high-grade Tantalum (Ta) mineralization
(Table 1):
1398 ppm Ta, sample 159116
1236 ppm Ta, sample 159219
725 ppm Ta, sample 159221
669 ppm Ta, sample 159117
559 ppm Ta, sample 159118
Generally, assays above 200 ppm Ta are considered to be ore grade. Tantalum is used in the electronics industry for
capacitors and high-power resistors (
https://www.chemicool.com/elements/tantalum.html
). It is also used to make alloys
to increase strength, ductility and corrosion resistance.

Historical drilling indicated that the Marko's pegmatite extends along strike for
190 m
in an east-west direction (MNDM
assessment report: 52L08SW2011). It has a shallow dip to the south and a maximum thickness of
15 m
. Marko's
pegmatite occurs in a tension fracture along an iron formation – gabbro contact at surface. North Marko's pegmatite lies
along a gabbro – mafic metavolcanics contact at surface,
20 m
north of Marko's pegmatite. Marko's pegmatite has a
central core of petalite surrounded by blocky pegmatite of quartz and K-feldspar which hosts the tantalum oxide
mineralization. On surface, Marko's pegmatite is along the contact of an iron formation and gabbro ridge. The historical
drilling did not test the western extension of the Marko's pegmatite which is open along strike. It should be relatively easy
to follow the edge of the iron formation and gabbro ridge to extend the strike length of the Marko's pegmatite.
Paterson Lake Property occurs within the Separation Rapids Greenstone Belt which is also home to the Big Whopper and
Big Mack petalite pegmatites. Separation Rapids Greenstone Belt is known as the Bird River Greenstone Belt in
Manitoba
which hosts the Tanco pegmatite.
Power Metals' Paterson Lake property consists of 106 cell claims within the Paterson Lake and Treelined Lake Areas.
The Property is approximately 7 km x 3 km in size. Power Metals optioned the Paterson Lake property in 2017 because
the property has multiple known petalite pegmatite dykes on surface, but yet is still underexplored.

Quality Control
The grab samples were transported to SGS analytical lab,
Ancaster, Ontario
by Manitoulin Transport. SGS analytical lab
in
Lakefield, Ontario
has ISO 17025 certification. Every 20 samples included one external quartz blank and one external
lithium standard. 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
