Grid Metals Drills High Grade Lithium Pegmatite

TORONTO, CANADA - Grid Metals Corp. (TSX-V: GRDM) (“Grid” or the “Company”) today

announced initial results from the winter 2018 drill program targeting the Main Dyke pegmatite at the

Mayville Lithium |Project. The first three of ele ven holes testing the pegmatite dyke intersected high

grade lithium and significant tantalum values. The objective of the initial phase of drilling is to test

the potential for a high grade, high purity lithium and rare metals bearing LCT pegmatite dyke.

Highlights from the initial three holes of the drill program are as follows:

 Drill core assays returned Li2O values in excess of 1.5% over the width of the dyke

with visual spodumene blades in each of the three holes.

 The iron content and other level of impurities are low

 Significant rare metals were encountered including tantalum

 The three holes were drilled over a strike length of 195 meters

Results from the first three holes are tabulated below:

consider the historical resource estimate as a current resource estimate and is not relying on the historical resource estimate as a current

resource estimate until such time as a Qualified Person has reviewed and confirmed the data.

In total eleven holes have been completed by the Company to test a strike length of approximately 775

metres. The Main Dyke remains open to the south and at depth. The drilling occurred in the area of

the 1950’s historical drilling which defined the historic al mineral resource but did not test for rare

metals.

“Our exploration objective is to explore for a high value per tonne spodumene pegmatite by virtue of

its lithium grade, rare metal by-products and purity” said Robin Dunbar, President and CEO of Grid. “

We look forward to receiving the balance of the drill holes which will give us a good idea of the

potential of the Main Dyke”.

The Main Dyke is one four known pegmatite dykes on the Mayville Lithium Property. The Property

has a total historical resource of 3.8 million tons grading 1.28% Li2O 1 from the Main Dyke and the

North Dyke. The pegmatite dykes are located at or near the lithological contact between the Maskwa

Lake Batholith and mafic volcanic rocks . This favourable contact horizon has been mapped for

approximately 10 kilometers along strike of the Mayville Lithium Property . The four known

pegmatites are located in an area approximately 1500 m by 1500 m just south of Mustang’s Mayville

Copper-Nickel deposit. Mustang has now staked the remaining prospective horizon and will in future

complete prospecting and geochemical analysis in the expanded project area.

Grid Metals acquired the M ayville Lithium Property in February 2018 from the Tantalum Mining

Corporation of Canada Ltd in return for a 2% Net Smelter Royalty and a first right to purchase products

produced from the property on commercial terms.

QA/QC, Analytical and Metallurgy Work

Core was logged and split at the Company’s Makwa warehouse where all drill core is stored. Samples

were sent to AGAT Laboratories in Thunder Bay, Ontario for crushing and preparation with the final

assays completed at the AGAT Laboratories in Mi ssissauga, Ontario. The samples are assayed using

a Sodium Peroxide Fusion with a ICP-OES/ICP-MS Finish.

Grid implements a QA/QC program on drill core including inserting blanks, duplicates and commercial

standards at regular intervals with all sample submissions to the laboratory.

About Grid Metals Corp.

Grid is focused on exploration and development of properties focused on the battery metals. It owns the

mineral rights to the Makwa Nickel -Copper Cobalt Property and the Mayville Copper-Nickel

Property both located in the Bird River Greenstone Belt in southeast ern Manitoba. The Company

completed a Preliminary Economic Assessment on the Makwa-Mayville Project in 2014. The Mayville

Lithium Property was acquired from Tantalum Mining Corpo ration of Canada Ltd. The Company

also controls mineral rights at the East Bull Lake Property west of Sudbury prospective for PGM and
