Grid Metals Intersects 13.75 Metres of 1.53% Li2O and 8.0 Metres of 1.47% IN First TWO Holes at the Donner Lake Lithium Property Manitoba Canada
GRID METALS INTERSECTS 13.75 METRES OF 1.53% Li2O and
8.0 METRES OF 1.47% IN FIRST TWO HOLES AT THE DONNER
LAKE LITHIUM PROPERTY MANITOBA CANADA
Toronto, Ontario, April 5, 2022 – Grid Metals Corp. (the "Company") (TSXV:GRDM)(OTCQB:MSMGF) is
pleased to report initial results from its 2022 lithium exploration program at its Donner Lake lithium
property in southeastern Manitoba. The Company completed 11 drill holes targeting the Northwest Dyke
– one of several known lithium-cesium-tantalum (LCT) -type pegmatite dykes on the property . All holes
at the Northwest Dyke intersected spodumene-bearing pegmatites over a strike length of 600m. Two drill
holes were completed on the West Dykes and numerous smalle r pegmatites were intercepted. The new
drilling at the Northwest Dyke was the first since 1955. The company is awaiting results on the other
holes. The project is located in southeastern Manitoba in the Winnipeg River pegmatite field, which hosts
the world-class Tanco Pegmatite.
Overview of Initial Drillholes
• At the Northwest dyke, a LCT-type pegmatite, the first hole of the program (GDL22-01)
intersected 13.75 metres averaging 1.53% Li2O including a maximum grade of 2.06% Li2O
starting at a downhole depth of 86 metres.
• GLD22-02 was drilled on the same setup at a shallower dip and intersected a 9.4 metre
pegmatite with 1.47% Li2O over 8.0 metres and a maximum grade of 2.28% Li2O starting at a
downhole depth of 57.0 metres.
• The pegmatite intersected in both holes contains visible spodumene quartz intergrowths (SQUI)
and discrete spodumene crystals (see photographs, below).
• Both intersections also have elevated tantalum (Ta), cesium and rubidium.
• The estimated true width of the Northwest Dyke from the initial two drill holes reported is 7 to 8
metres.
• In total, 11 holes were completed on the Northwest Dyke and established a minimum strike
length of 600 metres and a minimum vertical depth of ~200 metres.
• The Northwest Dyke remains open along strike in both directions and at depth.

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.
• Tanco is currently operating a lithium spodumene circuit at the Tanco Mine – the mine
is 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.
• Grid Metals has an exploration agreement in place with the Sagkeeng First Nation,
whose Traditional Lands include the Donner Lake and Mayville properties.
• The project has the opportunity to 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 property is significantly underexplored with a large portion of the prospective
geology having seen no prior lithium exploration.
Carey Galeschuk, Grid’s Vice President, Lithium, stated: “The strong and consistent grade from
our initial drill intercepts of the Northwest dyke is encouraging. The Donner Lake Lithium Property
remains prime hunting ground for additional LCT -type pegmatite discoveries. In this program at
the Northwest Dyke we are looking to see additional, good lithium grades within the host
pegmatite body along strike and to depth to enable us to build an initial NI 43 -101 mineral
resource. The vertical orientation, width and grade of mineralization observed in the first two
holes are certainly good indicators of the potential of the project” he added.
To date the Company has completed 13 exploration drill holes totalling 2,779 metres on the
Donner Lake lithium property . Eleven drill holes targeted the Nor thwest Dyke and two holes
targeted the West Dykes, located to the south. The program represents the first phase of drilling
at Donner Lake for 2022 . Complete analytical results for the Northwest Dyke intersections
reported here for holes GDL22-01 and GDL22-02 are provided in the Appendix.
The two best-defined dykes on the Property are the Main Dyke, which has been traced over strike
length of approximately 1 km, and the Northwest Dyke, the subject of the recent drilling. A non-
compliant historical resource of 3.8 million tons at a grade of 1.28% Li2O (Manitoba Mines Branch
Assessment file 91769A ) was calculated for the Main and Northwest dykes by ViolaMac Mines
Ltd. based on drilling completed in 1955. This resource estimate cannot be independently
verified by the Company. The Company is looking to complete additional drilling over the coming
months to establish a maiden NI 43-101 lithium resource on the Property.
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 located 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 (Thunder Ba y) 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.
