Foremost Lithium Announces a 7,500 Metre Winter Drill Program on

Its Zoro Lithium Property

Drilling at Zoro will Focus on Dyke 1 as It Is Open Along Strike and at Depth

Providing Excellent Potential for Further Resource Development

Vancouver, British Columbia – December 28, 2023 - Foremost Lithium Resource & Technology

Ltd. (NASDAQ: FMST) (CSE: FAT) (“Foremost Lithium”, “Foremost” or the “Company”), a North

American hard-rock lithium exploration company, is pleased to announce today its drilling plans

on its Zoro Lithium Property located near the historic mining centre of Snow Lake in Manitoba.

The Company is comple�ng plans in prepara�on of 30-hole, 7,500-metre diamond drill winter

program including submi�ng work permits at the Manitoba Mines Branch. The drill program on

the Zoro Property will be in addi�on to the Company’s recently announced 2,500 metre diamond

drill program on its Jean Lake Lithium/Gold Property located in the same mining centre . Drilling

on both proper�es will total 10,000 metres.

Foremost Lithium ’s Zoro and Jean Lake Proper�es share con�guous borders with Snow Lake

Lithium’s Thompson Brothers and Grass River proper�es , which are disclosed as having an

aggregate measured, indicated and inferred resource es�mate of approximately 8.2 million

tonnes of 1% Li2O . The Zoro Property is directly adjacent to the Thompson Brother’s (“TB”)

lithium trend, known for hos�ng several lithium enriched occurrences. The Zoro Property is also

adjacent to the Crowduck Bay Fault which is a significant regional focus for the development of

lithium-enriched pegma�te clusters (Figure 1).

Jason Barnard, Chief Execu�ve Officer and President of Foremost Lithium, comments: “This is the

most aggressive drill program our company has embarked on to date. With the most recent

announcement of drilling on our Jean Lake Lithium/Gold Property, we will be running two winter

drill programs on two different projects for a combined 10,000 metres of drilling this winter. We

are pleased to be working our first drill program with Dahrouge and feel confident that we will be

able to optimize our resource potential on both our Zoro and Jean Lake Properties to increase

shareholder value.”

Dyke 1

Drilling at the Zoro Property will focus on Dyke 1, which par�ally outcrops at surface and hosts an

inferred resource from a single high -grade lithium bearing spodumene pegma�te of 1,074,567

tons at a grade of 0.91% Li2O, with a cut-off of 0.3%, as set forth in the Company’s filed SK-1300

LEGAL_42770402.1

Technical Report Summary (2023) and NI -43-101 Technical Report (2018). Mineraliza�on is

defined for 265 metres along strike and to a depth of 265 m etres and atains widths of up to 40

metres. Dyke 1 has not been drilled since 2 018 and is open along strike and at depth providing

excellent poten�al for further resource development. Figure 2 (below) displays previous historic

drill holes in Dyke 1, but also highlights this Dyke 1’s poten�al in the upcoming drill program, as

it displays an abundance of undrilled area for further resource development.

Dahrouge Geological Consul�ng (“DGC”) conducted a summer explora�on program with the goal

of collec�ng surficial structural data to aid in drill targe�ng while also verifying the presence of

spodumene-mineralized pegma�te on surface at Dyke 1. DGC plans to further inves�gate the

spodumene-bearing pegma�tes on Dykes 8, 3 and 16 with this drill program (Figure 3).

Dyke 8

Dyke 8 has been previously intersected by eight holes (total of 98.25 m etres), intersec�ng high-

grade lithium in 36.5 metres of spodumene-bearing pegma�te, including, 12.3 metres of 1.1%,

Li2O, 4.4 metres of 1.2% Li2O and 2.2 metres of 1.5% Li2O. This Dyke has been defined over 120

metres in length, 5-15 metres in width and has been drilled to a depth of 157 meters and remains

o p e n i n a l l d i r e c � o n s . Dyke 3 is also open in all direc�ons and further drill tes�ng will be

performed to confirm the rela�onship between Dyke 8 and Dyke 3 (Figure 4).

DGC is currently finalizing all details of the Zoro Property winter drill program, including securing

all vendors and facili�es . Drilling is expected to commence in Q1 of 2024 and Foremost will

provide addi�onal updates in in due course.
