TORONTO, ON / ACCESSWIRE / 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 smaller 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.

About the Donner Lake Lithium Property
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 Northwest 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 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.
