Power Metals Corp.
("
Power Metals Corp.
" or the "
Company
")
(TSX VENTURE:PWM)(FRANKFURT:OAA1) (OTC:PWRMF) is pleased to announce 12 grab samples with
1.01 to 3.26 % Li
2
O from the recently discovered, Jesse's Pegmatite at Paterson Lake, 60 km north of
Kenora
, northwestern
Ontario
. Assay highlights of the Lithium (Li) mineralization on Jesse's Pegmatite
include (Table 1):

Lake. (CNW Group/POWER METALS CORP)
In addition to Lithium mineralization, the petalite dykes in the Jesse's Pegmatite area contain Tantalum (Ta)
mineralization. Assay highlights include:
271 ppm Ta, sample 159143, Jesse's pegmatite
249 ppm Ta, sample 159348, South dykes
224 ppm Ta, sample 159165, South dykes
Jesse's Pegmatite area consists of multiple parallel petalite pegmatite dykes with a east-west strike. Based
on grab sampling and mapping Power Metals has identified the following clusters of dykes:
North Dykes
Dykes between North and Central
Central Dykes (named Jesse's Pegmatite)
South Dykes
This area has significant exploration potential, as the distance between the North and South Dykes is
190
m
. Stripping is recommended to identify more dykes in the area and to expand the strike length of each
individual dyke.
Dr. Selway, VP of Exploration, stated "We are so excited with the discovery of Jesse's pegmatite at
Paterson Lake. I am looking forward to a future drill program which has already been permitted at Paterson
Lake on Marko's pegmatite and stripping and drilling on Jesse's Pegmatite. We now have two drill ready
properties with huge potential in addition to our flagship Case Lake property."
All of the petalite dykes are deformed and sheared similar to that at Avalon's Separation Rapids Lithium
Property located 3.7 km to the west. The dykes are characterized by recrystallization textures and banding.
The pegmatite dykes are hosted by metasedimentary and mafic metavolcanics rocks which occur along
ridges. The pegmatite dykes are zoned with fine-grained aplite outer zones enriched in Ta and coarse-
grained petalite-K-feldspar-quartz-muscovite with trace garnet core zones enriched in Li.
The North Dykes contain up to 1.93 % Li
2
O (sample 159337) and up to 153 ppm Ta (sample 159151).
Pegmatite dykes between North and Central Dykes contain up to 1.41 % Li
2
O (sample 159334).
The Jesse's Pegmatite dykes are up to
30 m
wide in outcrop with up to 3.26 % Li
2
O (sample 159145)
and up to 271 ppm Ta (sample 159143). Petalite crystals are up to 4 cm in sample 159145 with 3.26
% Li
2
O.
The South dykes are dominated by Ta mineralization rather than Li with 200-2449 ppm Ta.

O, Jesse's Pegmatite, Paterson Lake.
The dykes all have the same roughly east-west strike as the other pegmatites in the Separation Rapids
Greenstone Belt. Jesse's, Rhea's and Cook's pegmatites are along the same contact between mafic
metavolcanics and metasediments as other petalite pegmatites historically mapped by Ontario Geological
Survey: Draven, Black Bear, Ballpeen, Pegmatites # 5, 6, 7, 8, 9, 10 and 11.
Jessse's pegmatite was first discovered in
June 2018
with grab Sample 159021 while mapping between
Cook's and Rhea's Pegmatite (press release
July 30, 2018
) and then Power Metals followed up with a
mapping program in early
September 2018
. The pegmatite was named after
Jesse Koroscil
, Power Metals
senior geologist, who found it. Jesse was also responsible for the discovery of spodumene on East Dyke
and Northeast Dyke at Case Lake, east of
Cochrane, Ontario
(press release
Oct. 10, 2017
and
Nov. 13,
2017
).
About
236 m
west of Jesse's North Dykes, along the same metasedimentary ridge, another petalite
pegmatite was discovered with 0.94 % Li
2
O. This West Dyke is a possible extension of the North Dykes.
This West Dyke has the same mineralogy as Jesse's pegmatite indicating significant exploration potential to
find more petalite dykes along this
236 m
long ridge (Figure 2).

The summer 2018 mapping program on Paterson Lake focused along two parallel east-west petalite
pegmatite trends: mapping on one trend resulted in the confirmation that Marko's pegmatite is on Power
Metals Property and mapping on the other trend resulted in the discovery of Jesse's Pegmatite.
Exploration on Marko's Pegmatite highlights over
268 m
strike length include:
3.36 to 4.43 % Li
2
O range for 13 grab samples.
559 to 1398 ppm Ta range for 5 grab samples.
Identified 19 historic drill holes are on Power Metals' Paterson Lake Property.
historic drilling that showed that there is both Lithium and Tantalum mineralization at depth on the
Marko's pegmatite and it is not just one pegmatite dyke but two: Marko's and North Marko's.
The Marko's pegmatite is one of the top three pegmatites for Lithium and Tantalum mineralization in the
Separation Rapid Greenstone Belt and is drill ready. 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.
At Jesse's and Marko's pegmatites, 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.
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.
Power Metals has approved Exploration Permits from Ontario Ministry of Energy, Northern Development
and Mines for drilling on both Paterson Lake and Gullwing-Tot Lakes Properties. Both Properties are drill
ready.
Quality Control
The grab samples were transported to SGS analytical lab,
Lakefield, Ontario
by Manitoulin Transport. SGS
analytical lab 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
2
O. A QA/QC review of the standards and blanks for this
mapping program indicate that they passed and the assays are accurate and not contaminated.
