Grid Metals Corp Completes 15 Drill Holes at Donner Lake Lithium Project Drilling Ongoing

Exploration Programs

GRID METALS CORP COMPLETES 15 DRILL HOLES AT DONNER LAKE

LITHIUM PROJECT

DRILLING ONGOING

November 29, 2022 Grid Metals Corp (TSXV:GRDM; OTCQB:MSMGF) (the "Company") today provided a

progress update on its drill program at its Donner Lake Lithium Property (the "Property"), located in the

Bird River Greenstone Belt of southeastern Manitoba. The program will include resource delineation

drilling at the Main and Northwest dykes and a series of exploration holes targeting untested spodumene

bearing pegmatites. The Company maintains the near-term goal of establishing a maiden resource from

the Main and Northwest dykes via the current drilling program. The property is a 75%/25% joint venture

between Grid Metals Corp. and Lithium Royalty Corp.

Drill Program Update

Main Dyke Drilling

The Company currently has two drills in operation on the Main Dyke and 15 holes for approximately 3400

meters have been completed since the start of the drilling several weeks ago. The Main Dyke is being

drilled at an average pierce point spacing of 75 to 90 meters and approximate vertical depths of between

100m and 250m . This work will complement shallow drilling completed in 2018 and surface channel

sampling completed earlier in 2022. Pegmatite units have been encountered in every hole. The 11 holes

completed in the 2018 drilling program returned average grades of 1.5% Li2O over true widths of

approximately 3 metres at an average vertical depth of approximately 50 metres and over a strike length

of approximately 760 metres. Historical drilling from 1955 on the dy ke covered a strike length of 810

metres. The Main Dyke remains open along strike and to depth.

Later in the program resource delineation drilling will also be completed at the Northwest Dyke where

fifteen (15) exploration holes were completed by the Com pany in the first quarter of 2022. The fifteen

drill holes cover a strike length of 500 metres and returned intersection depths of <100 to >250 metres.

The results of that program indicated that the near surface part of the Northwest Dyke has an averag e

true thickness of ~ 4 metres and an average grade of 1.3% LiO2 (see the Company’s July 28, 2022 New

Release for details). The Northwest Dyke remains open along strike in both directions and to depth.

Exploration Drilling Plan: Several other exploration targets in the area of the Main and Northwest Dykes

are planned to be drilled in the course of the current drill program. Targets include two outcropping dykes

systems. At the Southwest Dykes, 19 surface grab samples were taken of the surface pegmatites with 6

samples yielding assay values greater th an 0.4% Li2O with the highest assay being 2.93% Li2O (Table 1).

The 19 samples were also anomalous in cesium, rubidium, and tantalum. At the South Dykes surface

grab samples also returned anomalous lithium values and tantalum values (up to 579 ppm).

The Company expects to generate additional exploration targets for future drilling through the

integration of surface prospecting and mapping data , historical and recent lithogeoc hemical analyses,

and 2D and 3D geophysical models of both magnetics and apparent resistivity.

Additional Information

The Southwest Dykes were mapped in the summer over an inferred strike length of greater then 250

meters. In the field the dykes were averaging 1.3 meters widths. Fine to coarse grained spodumene blades

were noted in the field investigation and assays are provided below. The maximum surface sample Li2O

grade was 2.93%. The trend of the pegmatites exposed on surface at the Southwest and South Dykes are

is similar to the trends of the Northwest and Main Dykes, i.e., steeply dipping with a northeasterly strike

direction.

QAQC

The exploration program at Donner Lake is being supervised by Carey Galeschuk , P.Geo., who is an

experienced lithium geologist with nearly 2 decades of exploration experience in the Bird River Belt with

Grid Metals, Tantalum Mining Corporation of Canada and other companies . Grid Metals applies best

practice quality assurance and quality control ("QAQC") protocols on all it ’s exploration programs. For

the Donner Lake Lithium Project 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 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 mat erials ("CRMs") and an

analytical blank for the program to monitor analytical accuracy and check for cross contamination

between samples.

Mr. Galeschuk has reviewed and approved the contents of this press release with respect to NI 43 -101
