Vancouver, British Columbia--(Newsfile Corp. - March 6, 2023) - Foremost Lithium Resource & Technology Ltd. (CSE: FAT) (OTCQB: FRRSF) (FSE: F0R0) (WKN: A3DCC8) ("Foremost Lithium", "Foremost" or the "Company") is pleased to announce receipt of the phase two of its metallurgical report from XPS Expert Process Solutions, A Glencore Company (XPS) for Dyke 1 on its Zoro Lithium Property located in the mining friendly province of Manitoba. Final test results confirm The Dense Media Separation ("DMS") and flotation of DMS Middlings together, achieved a global lithium recovery of 81.6% at a spodumene concentrate grade of 5.88% Li2O. Pyrometallurgical and hydrometallurgical testing on the DMS spodumene concentrate have shown that the final product is amenable to a flowsheet, capable of producing both battery grade lithium products, Lithium Carbonate (Li2CO3) and Lithium Hydroxide (LiOH).

Jason Barnard, Foremost's President and CEO, comments, "Phase two of our metallurgical program at Dyke 1 confirms the ability to produce a near 6% Li2O concentrate while maximizing lithium recovery with significant CAPEX and OPEX savings. This was a critical milestone for our company which highlights the quality of our ore to prospective battery manufacturers and other strategic partners while our lithium is still in the ground. We recognize that the world is transitioning towards electrification with unprecedented speed, and we are positioning our lithium projects to capitalize on these opportunities."

Dyke 1 Metallurgy

The Dyke 1 metallurgical program was initiated in June of 2022 after receipt of a permit from the Manitoba government and the collection of a 489 kg of spodumene-mineralized pegmatite from historic trenches exposing Dyke 1 on the Zoro property (c.f. December 7, 2022, news release). After sample preparation, test work on this Master Composite sample included heavy liquid separation (HLS), dense media separation (DMS, see fig 1), and dry magnetic separation at SGS Lakefield. Dr. Sunil Koppalkar of XPS, oversaw the metallurgical work on behalf of Foremost Lithium.

Results of Test Work

The Zoro Dyke 1 metallurgical program investigated the feasibility of lithium beneficiation by dense media and dry magnetic separation with the goal of producing a 6% Li2O concentrate from a Master Composite, at a fairly coarse particle size of -12.7/+0.5 mm. Completed HLS, DMS, and dry magnetic separation test work confirms that heavy liquid separation (HLS) demonstrates excellent potential for the recovery of an on-spec lithium concentrate from the Master Composite by dense media separation. The global lithium recovery to a cumulative HLS non-magnetic sink product at an interpolated 6% Li2O grade was high at 73.5%, at a projected SG cut-point of 2.88. Results from HLS testing were confirmed in the DMS pilot plant. DMS processing followed by dry magnetic separation produced a 5.93% Li2O spodumene concentrate, at a global lithium recovery of 66.9%, in approximately 27% of the mass which is in good agreement with the HLS results. The iron contents in the final lithium concentrates from both HLS and DMS were slightly above the 1% Fe2O3 requirement, but still acceptable for subsequent hydrometallurgical lab testing. Further improvements on the recovery of lithium can be realized by incorporating flotation and wet high-intensity magnetic separation (WHIMS) in the flowsheet to treat the DMS middlings and -0.5 mm fines.

Vice President of Exploration, Dr. Mark Fedikow, notes, "Favourable metallurgical characteristics and processing of the Dyke 1 mineralogically representative bulk sample have been confirmed by this two-phase program. The result provides confidence in the metallurgical character of spodumene-bearing pegmatite as exploration proceeds on the Zoro lithium property."

Foremost would like to announce the Board of Directors (the "Board") unanimously voted on January 24, 2023, to appoint Jason Barnard to the role of President and CEO, thereby removing the interim President and CEO designation previously in place. Mr. Barnard's extensive knowledge of the company, capital markets and the base metals space make him ideally suited to build investor confidence and enhance shareholder value for Foremost and all its stakeholders.

Foremost would like to announce a resolution to the litigation involving former management, Robert Dinning and John Gammack previously disclosed in Foremost's audited financial statements. Foremost has not found any evidence of wrong-doing by Messrs. Gammack and Dinning. Foremost has agreed to pay $5000 to each individual towards their legal costs and the parties have agreed to dismiss the claim and counterclaim.
