About Grit Metals Corp.

Grit Metals Corp. is a junior mining company currently focused on the Lithium-Cesium-Tantalum Finnish Pegmatite Project in central Finland. Governing bodies in Europe and Finland are legislating environmentally friendly and energy independent laws and policies. One of the key components is access to REE and, specifically, lithium. The company's exploration licenses are located within 1 kms of the Keliber mine and production complex, currently under construction and expected to begin production in H2 2025.

An estimated €600 million investment by Keliber's parent company Sibanye-Stillwater Limited in partnership with the Finnish Minerals Group (www.mineralsgroup.fi) is underway in the Kautinen Region and will see the development of open-pit and underground mining from several deposits, construction of a central spodumene concentrator plant and a lithium hydroxide chemical plant at tidewater in Kokkola. When completed, this complex will comprise a complete hard-rock spodumene pegmatite lithium supply chain (source: www.sibanyestillwater.com).

It is anticipated that certain directors, officers or other insiders of the Company will acquire Units. Such participation will each be considered a "related party transaction" within the meaning of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company intends to rely on the exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a) of MI 61-101 in respect of the Offering due to the fair market value of the related party participation being below 25% of the Company's market capitalization for purposes of MI 61-101. The Company will file a material change report in respect of the Offering. However, the material change report will be filed less than 21 days prior to the closing of the Offering, which is consistent with market practice and the Company deems reasonable in the circumstances.

On behalf of the board of directors of the Company:

Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
