Vancouver, British Columbia--(Newsfile Corp. - May 9, 2023) - Foremost Lithium Resource & Technology Ltd. (CSE: FAT) (OTCQB: FRRSF) (FSE: F0R0) (WKN: A3DCC8) ("Foremost Lithium", "Foremost" or the "Company") is pleased to announce that it has entered into an agreement (the "Amending Agreement") amending the terms of it's proposed acquisition of the Lac Simard South Property (the "Property"), previously announced on March 20, 2023. Under the amended terms, the Company will acquire an aggregate of 60 claims located in the Province of Quebec, covering 8,612 acres/3,485 hectares which host 12 identified pegmatites via satellite imagery (the "Lac Simard South Property") from arm's length vendors (the "Vendors"). In addition, Foremost has independently staked and recorded 20 additional mineral claims which are contiguous with the borders of these 60 claims, which resulted in an increase of Lac Simard South land package to 80 mineral claims and to the total area to 11,482 acres/4,647 hectares.

Jason Barnard, Foremost Lithium's President and CEO, comments, "We are pleased to move ahead with this acquisition to plant Foremost's footprint in Quebec, one of Canada's busiest, and friendliest mining regimes. The Company re-evaluated the acquisition and determined we would tighten the land package that is being acquired to focus on the core, strategic claims while incurring cost-savings to our stakeholders. We look forward to beginning our exploration and prospecting efforts this summer in this active lithium camp."

Lac Simard South Property is located approximately 90km southwest from the NAL Lithium Processing Plant (a Piedmont/Sayona Joint Venture) which just commenced producing lithium spodumene concentration out of its facility¹ and is situated 80km southwest of Val-D'or, an established logistics hub for mining services. The Property is easily accessible year-round by way of well-maintained roads, with little overburden. Quebec is a major producer of electricity and one of the largest hydropower generators in the world. A hydroelectric power plant is situated within the property claim block, allowing access to grid power and low‐cost hydroelectricity.

Sayona Mining Limited's Abitibi Hub, comprised of its North American Lithium, Authier Lithium and Tansim Lithium projects located nearby, boasts a measured and indicated resource of 87.8 Mt grading 1.05% Li2O (Source: https://sayonamining.com.au/announcements/ March 22, 2022). Lac Simard South is contiguous to Sayona Mining Limited and Refined Metals Corp which has sampled 2.1% lithium (Li) 4.52% Lithium Oxide (Li2O) and 5.88% Tantalum Oxide (Ta2O5) (Ref. Report GM 36797, 1980). https://refinedmetalscorp.com/lac-simard-property/.

Geology

Lac Simard South property is largely underlain by the large monzodiorite batholith of Lac Simard Sud. This batholith is pinkish grey in color and is composed of plagioclase, K-feldspar hornblende with minor amount of epidote and quartz. Quartz-monzodioritic dykes and sills are observed at the margin of this intrusion. A gabbroic intrusion lies to the southwest end of the Property and hosts the Laforce showing. This Ni-Cu showing was explored by Kerr Addison Gold Mines Ltd and more lately by Fieldex Exploration (2007) and lies about 1km south of the Property. The Property contains 12 pegmatites based on satellite imagery.

Acquisition Terms

Pursuant to the Amending Agreement, the Company will acquire the amended Lac Simard South Property for aggregate cash consideration of $35,000, plus GST with $17,500 plus GST payable upon closing and an additional $17,500 plus GST payable within 4 months after closing. In addition, the Company will issue a total of 535,000 shares common shares of the Company at $0.15 per common share. There are no warrants issuable to the Vendors under the new terms. The common shares will be subject to a hold period of four months pursuant to applicable securities laws.
