Grid Metals Intersects 7 m at 1.28% Li2O at over 125 m Below the Previously Deepest Drill Holes at Donner Lake; Provides Project Update

TORONTO, April 18, 2024 - Grid Metals Corp. (TSXV:GRDM);(OTCQB:MSMGF) ("Grid" or the "Company") is pleased to announce drill results from its January-March 2024 drill program at the Donner Lake Lithium Project ("Donner Lake") in southeastern Manitoba, Canada. Drilling was completed at both: (1) the Northwest Dyke ("NW") Dyke for the purposes of upgrading the near surface resource; and (2) at depth below the Main Dyke resource to test the potential for adding to the existing underground resources. The results from both dykes were in line with expectations and support the ongoing development timeline for Donner Lake. The Company is continuing study and permitting activities to position Donner Lake for higher lithium prices in the future.

Drill Highlights

• The two drill holes at the Main Dyke intersected the spodumene-bearing Main Dyke approximately 125 meters beneath the previously deepest drill holes. Both holes were drilled to test the potential for extending the existing underground resources at depth. Based on these new results and the consistent nature of the Main Dyke over its ~1 km strike length, Grid Metals plans to proceed with a fully-funded summer drill program comprising ~10 additional resource extension drill holes.
• All of the 12 infill drill holes at the Northwest Dyke intersected spodumene-bearing pegmatite that returned lithium grades and intersection lengths in line with previous resource delineation drill holes completed in 2022 and 2023. Highlights from the 2024 winter drilling included 7 m at 1.85% Li₂0 and 12 m at 1.25% Li₂O. Overall, the Company expects this drilling to enable an upgrade to the resource category at the Northwest Dyke.
• Drill highlights include (a complete table of results are provided in Table 1):
  • GDL 24-01: 6.9 m at 1.28% Li₂O starting at 467.4 m (Main Dyke extension drilling)
  • GDL 24-03: 3.2 m at 1.56% Li₂O starting at 422.8 m and 2.3 m at 1.50% Li₂O starting at 428.9 m (Main Dyke extension drilling)
  • GDL24-07: 6.7 m at 1.85% Li₂O starting at 84.6 m (Northwest Dyke infill drilling)
  • GDL24-09: 11.5 m at 1.25% Li₂O starting at 101.5 m (Northwest Dyke infill drilling)
  • GDL24-10: 7.8 m at 1.50% Li₂O starting at 28.9 m (Northwest Dyke infill drilling)
  • GDL24-13: 7.4 m at 1.62% Li₂O starting at 52.3 m (Northwest Dyke infill drilling)

Project Update
The Company has now completed significant work towards a NI 43-101 compliant Preliminary Economic Assessment ("PEA"). The project design is based on mining at the Donner Lake Lithium Project and trucking of the material to the True North Mill in Bissett, Manitoba. The major consultants working on the PEA are Primero Engineering and Mining Plus, who are supported by Arsalan Talebzadeh, P. Eng., a consultant to the Company. Major components of the study have been substantially completed including a mine plan, capital and operating cost estimation and a number of optimization trade-off studies.

The Company is continuing optimization work including further metallurgical test work from the NW Dyke. Grid is also actively continuing with permitting initiatives to obtain an Advanced Exploration Permit for the Donner site. A comprehensive update will be provided in the coming weeks.

Other Activities
The Company is in the final stages of preparing an updated mineral resource estimate for its Makwa Mayville ("MM") Copper Nickel Project, located approximately 150 km from Winnipeg. The Project consists of the Makwa resource (which is nickel dominant) and the Mayville resource (which is copper dominant). Mayville is located immediately adjacent to the Donner Lake Lithium Project and is accessible by the same road network. Donner Lake, Makwa and Mayville are located in the traditional territory of the Sagkeeng First Nation with whom Grid signed an Exploration Agreement in April 2021.

Robin Dunbar, Chief Executive Officer of Grid Metals Corp., stated, "the current market conditions for lithium are very challenging in light of the decline in prices for lithium products in the past year. However, we have taken the initiative to continue development of the Donner Lake Lithium project and related permitting activities to take advantage of the anticipated rebound in prices expected to occur later in 2024 and into 2025. The Company plans further updates to shareholders in the coming weeks on the PEA and permitting initiatives, as well as drill results from our Falcon West Lithium Property. We remain committed to advancing Donner to become one of the next permitted lithium projects in North America."

Discussion of Drill Results
A summary of the drill results (Table 1) and a plan view location map (Figure 1) are shown below:

Table 1: Selected pegmatite intersections and weighted average lithium oxide grades for the Main and Northwest dykes, Donner Lake Lithium Project. True widths are estimated to represent between 40-80% of the reported intersection lengths.

Figure 1: Donner Lake Plan Map with January-March 2024 drill results

The current results relate to 14 diamond drill holes completed at the Main and Northwest dykes during the months of January, February and March 2024.

At the Main Dyke, two holes were drilled ~100 metres vertically beneath the previously deepest drill holes. Both holes intersected the Main Dyke at the expected depth and returned true widths and weighted average Li₂O grades consistent with previously reported resource drill hole intersections. The new results suggest that there are very good prospects for adding, with appropriate deep drilling, new underground resources below the current inferred resources.

Figure 2: Main Dyke long section

A total of 12 holes and 1,332 metres were completed at the Northwest Dyke. Results for 9 of these holes were available at the time of writing and are reported here. All 12 holes intersected the spodumene-bearing NW dyke at the expected depth. The 9 holes reported here returned weighted average lithium grades over true widths in line with the results reported in the 2023 resource estimate for the Property (see Company news release dated July 18, 2023 and associated Technical Report filed on SEDAR on September 6, 2023). The new results will be used to support the conversion of existing, open pit inferred resources to the indicated category.

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 Greenstone 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 materials ("CRMs") and an analytical blank for the program to monitor analytical accuracy and check for cross contamination between samples.

Mr. Galeschuk P Geo is the Qualified Person for Grid Metals Corp. who has reviewed and approved the contents of this press release with respect to NI 43-101 reporting guidelines.
