New High-Grade Lithium Intersections at Donner Lake Lithium Project; Field Program Underway
New High-Grade Lithium Intersections at Donner Lake Lithium
Project; Field Program Underway
Toronto, Ontario, June 21, 2022 – Grid Metals Corp. (the "Company") (TSXV:GRDM)
(OTCQB:MSMGF) is pleased to report additional drilling results from the Phase 1 drill program
at its Donner Lake lithium property (the "Property") in southeastern Manitoba. In addition, the
Company has started field work at the Property that will initially focus on sampling of several
previously mapped pegmatite dykes. The project is located in the Winnipeg River pegmatite
field, which hosts the world-class Tanco pegmatite and the associated Tanco lithium-cesium-
tantalum mine and concentrator. The project is a 75%/25% joint venture between Grid Metals
Corp and Lithium Royalty Corp., a leading player in global lithium finance.
Drilling Highlights:
• New d rill intersections of the Northwest Dyke include the following length-weighted
average grades:
o 8.2 metres averaging 1.53% Li2O in GDL22-07 (from 103.5 metres) including 5.5
metres averaging 1.96% Li2O
o 14.6 metres averaging 1.25% Li2O in GDL22-11 (from 141.7 metres) including 5.8
metres averaging 1.74% Li2O
o 3.26 metres averaging 1.88% Li2O in GDL22-14 (from 178.8 metres)
• Anomalous cesium and tantalum values were also encountered in the new holes including
maximum individual sample grades of 2850 ppm Cs2O (GDL22 -11) and 509 ppm Ta2O5
(GDL22-10).
The Northwest D yke has been traced by drilling for ~600 metres along strike and to a vertical
depth of ~250 metres. It is the second drill -defined LCT type pegmatite w ith significant strike
length on the Donner Lake property. Similar lithium grades were previously reported for the
Company’s 2018 drill holes targeting the Main Dyke, which is located ~1.5 km to the east of the
Northwest Dyke. Note that t he Northwest Dyke intersection lengths reported above do not
represent the true thickness of the dyke, which is estimated to typically range from 4 to 8 metres,
representing 50-70% of the reported intersection lengths. Complete analytical results for hoes
GDL22-07, -10, -11 and -14, together with drill hole specifications for these and previously
reported holes, are provided in the Appendices accompanying this release. Hole locations are
shown on the accompanying plan view map and longitudinal section. Core photos from the newly
reported holes are included below.
Field Program Underway
The Company has mobilized geological crews to the property to sample the known pegmatite
dykes on the property. Known pegmatite dykes include the West Dyke swarm, the South
Dykes and several other pegmatites on the east part of the property that were mapped by Grid
in 2012. A map showing the location of the target dykes is attached. Follow up work will
include a lithogeochemical survey to vector to unexposed LCT type pegmatites.
The property is viewed by Grid as very prospective for other lithium bearing LCT type pegmatite
dykes. The focus is on identifying new drill targets to complement the Northwest and Main
Dykes which have been the target of drilling to date.

Mr. Carey Galeschuk, Grid’s Vice President, Lithium Exploration, stated, "We continue to see
consistently good widths of high-grade lithium from the recent Northwest Dyke drilling. In
addition to our drilling we look to rapidly progress the Donner Lake discovery process with the
identification of new drill targets in the field. With the combination of results to date, geological
prospectivity and access to infrastructure we view the project as having great potential."
Quality Assurance and Quality Control
Grid Metals applies best practice quality assurance and quality control ("QAQC") protocols on all
of its exploration programs. For the Donner Lake drilling program, core was logged and sampled
at the Company’s core facility lo cated on the Makwa Property. Generally, 1.0 metre sample
lengths were used. Samples were bagged and tagged and then transported by secure carrier to
the Actlabs (Thu nder Bay) laboratory for sample preparation and analysis for lithium, cesium,
tantalum and selected major and trace element abundances using a sodium peroxide fusion total
digestion method followed by ICP-OES and ICP-MS analysis. The Company is using two lithium +
rare metal certified reference materials ("CRMs") and two analytical blanks for the Donner Lake
program to monitor analytical accuracy and check for cross contamination between samples.

About the Donner Lake Lithium Property
• The Property is owned 75% by Grid Metals Corp. and 25% by Lithium Royalty Corp.
(LRC), which is funding 25% of the current exploration program. LRC holds an overriding
2% royalty on the property.
• The Property was acquired by Grid from Tantalum Mining Corporation of Canada
Limited (Tanco) which has the first right to acquire products produced from the
property at commercial terms and holds a 2% royalty on certain claims.
• Sinomine Canada is currently operating a lithium spodumene circuit at its Tanco Mine
facility, located approximately 35 km to the southwest of the Donner Lake Property.
• Donner Lake is only 180 km from the provincial capital of Winnipeg and accessible by all
season roads and logging trails and there is nearby access to Canada’s major east-west
railway line.
• Grid Metals has an exploration agreement in place with the Sagkeeng First Nation,
whose Traditional Lands include the Donner Lake and Mayville properties.
• The Property has nearby access low-cost renewable power from Manitoba’s extensive
hydro-electric grid.
• There are multiple LCT-type pegmatite dykes on the Property including the Main Dyke
that, in 2018, was drill tested by Grid over a ~1 km strike length. The dykes are located
along a ~9 km long prospective geological contact between the Bird River greenstone
belt and the Makwa Lake batholith and occupy obvious structural trends.
• The Main Dyke and Northwest Dyke tog ether supported a non -compliant historical
resource estimate of 3.8 million tons at a grade of 1.28% Li2O (Manitoba Mines Branch
Assessment file 91769A). This resource estimate cannot be independently verified by the
Company. The Company is looking to complete resume drilling later this year to establish
a maiden NI 43 -101 lithium resource and continue exploration for other LCT -type
pegmatites on the Property.
• The Property is significantly underexplored with a large portion of the prospective
geology having seen no prior lithium exploration.
