Grid Metals Corp Announces More Lithium Drill Results from Donner Lake

Drill Results

GRID METALS CORP ANNOUNCES MORE LITHIUM DRILL RESULTS

FROM DONNER LAKE

February 22, 2023. Grid Metals Corp (TSXV:GRDM; OTCQB:MSMGF) (the "Company") today reported

results from an additional 12 holes at its Donner Lake Lithium Property (the "Property"), located 150 km

northeast of Winnipeg Manitoba. The drilling is part of the maiden 43-101 compliant resource delineation

program at Donner Lake. The current phase of drilling at the Main Dyke has now been completed.

• Results continue to outline a steeply -dipping LCT-type pegmatite dyke with visible spodumene

mineralization.

• All holes drilled to date in the 800m core resource area have hit the Main Dyke and all holes

reported to date have returned significant lithium values.

• Sub-parallel spodumene-bearing pegmatites have also been intersected in many of the completed

holes in both the footwall and hangingwall of the Main Dyke.

• The Main Dyke remains open at depth and along strike.

• Resource drilling is now commencing at the Northwest Dyke located 1 km to the west to follow

up on drilling completed in 2022.

• Drilling for a maiden lithium resource for both the Main and No rthwest dykes is on track for

completion by the end of March 2023.

• A metallurgical test program involving composite samples from both the Main and Northwest

dykes is nearing completion and will be reported on in the near future.

Donner Lake is currently a 75% / 25% joint venture with Lithium Royalty Corp. Grid has an MOU in place

with Tantalum Mining Corporation of Canada Limited focused on creating a toll milling operation to

process spodumene-bearing pegmatites from Grid’s Donner Lake Property.

Assays from the newly reported drill holes at the Main Dyke are shown below.

Discussion and Analysis

The Main Dyke resource delineation drilling has confirmed a mini mum vertical depth of approximately

350m over a minimum strike length of approximately 800 metres . The Company is pleased to note that

the deepest holes completed to date at the Main Dyke continue to show excellent spodumene content

and consistent widths.

Resource drilling will now shift to the Northwest Dykes where a ~ 600m strike length has been outlined

for delineation.

The Company is pleased to note that it has received initial results from a drone mag survey over the core

area at Donner Lake. The s urvey results will be integrated with lithogeochemical data generated by the

2022 field program to assess and prioritize new exploration targets for the property.

About Donner Lake Lithium

Donner Lake Lithium is a 75%/25% joint venture project between Lithium Royalty Corp and Grid Metals

Corp. with Grid Metals as the project operator. Resource drilling at two known LCT spodumene bearing

dykes is expected to be competed by end of March 2023 to be followed by an initial NI 43 -101 resource

estimate. An Advanced Exploration Permit application is being prepared which would enable a bulk

sample which planned to be completed at the nearby Tanco Mine – Canada’s only hardrock lithium

producer. Grid has a MOU in place with Tanco for possible toll milling at the Tanco Mine.

QAQC

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

experienced lithium geologist with nearly three 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 a nd 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 an

analytical blank for the program to moni tor 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

reporting guidelines.

About Grid Metals Corp.

Grid Metals is focused on both lithium and Ni-Cu-PGM in the Bird River area approximately 150 km north
