JEAN LAKE LITHIUM GOLD PROJECT
On July 30, 2021, we entered into an option agreement for the 2,476-acre/1,002-hectare Jean Lake Lithium-Gold Project, located in the Snow Lake District of Manitoba. This five-claim property lies on the eastern portion of the Proterozoic Flin-Flon-Snow Lake greenstone belt of the Canadian Shield. This area is known for hosting world-class gold, and gold-rich base-metal deposits and for the development of lithium resources.

Jean Lake Property Highlights Include
- Power access through the property
- Year-round access
- Airstrip located 5 km to the northwest.
- Highway access within 11 km.
- Rail access 35 km to the south.
- Entrained within the Thompson Brothers Lithium Trend
Jean Lake remained unexplored for lithium since 1942 until Foremost Lithium began exploration efforts in the late summer of 2021. The Manitoba Mineral Development Fund ("MMDF") provided funding by way of a $300,000 grant, stimulating exploration on the property. The Beryl B1, B2 and B3 pegmatite dykes were re-discovered on the Jean Lake property in 2021 by prospecting beneath 80 years of organic and inorganic debris during this initial summer prospecting program.
Rock chip samples of spodumene-bearing mineralization were collected in August 2021 from blast material in two trenched locations of the Beryl pegmatites. Two of the samples were apple green, coarse grained spodumene and three samples were from straw-colored finer grained spodumene. Results of all samples returned high-grade lithium contents regardless of the textural characteristics of the spodumene. SGM-3, now referred to as the Beryl dyke or B1 returned assays of 3.89% and 5.17% Li2O and occurs to the south of Snow Lake Lithium’s high-grade Sherritt Gordon (SG) and Grass River (GRP) spodumene pegmatites. Rock chip samples were also collected for assay and returned assay results with maximum contents of 20.9 g/t gold. All but one sample exceeded 1 g/t gold.

Ongoing exploration, consisting of prospecting and geochemical surveys, continued in June 2022 utilizing the results from recently completed UAV-borne magnetic surveys. The UAV surveys were conducted between November 29, 2021, and December 20, 2021, and comprised 483.4-line km. The technology was utilized to aid in the definition of new prospective drill targets by producing high-resolution magnetic imagery, to define the 3D location, shape, size, and distribution of potential spodumene rich pegmatite dykes. The Company’s exploration efforts have focused on lithium in pegmatite using a variety of exploration technologies, which not only have exposed potential for spodumene, but which have also demonstrated the potential for gold mineralization.
An inaugural drill program was announced on November 21, 2022, to test 14 high quality targets based on the integrated results of UAV-borne magnetic surveys, rock and soil geochemical surveys and outcrop prospecting. The drill program commenced December 2, 2022, and in June 2023, the results of the completed 3,002 meters diamond drill program were released. Assay results are based on a quality assurance and quality control program using industry best practices. Lithium and related elements are determined by ICP-MS after total sample dissolution and gold is determined by 30-gram assay and INAA finish. For assays above 5 g/t Au, a sub-sample of the original pulp is re-assayed with a gravimetric finish. Samples with visible gold are analyzed by metallic screen assay.

The Jean Lake drill program intersected numerous gold mineralized intervals at vertical depths up to 110 m below surface as well lithium at the B1 spodumene bearing pegmatite. The locations of drill holes that intersected gold mineralized intervals are illustrated in Figure 3, in addition to the B1 drill hole location. Details of the drilled gold and lithium intersections are provided in Table 1.

Gold mineralization in the area occurs in association with finely disseminated to blocky arsenopyrite with lesser pyrite and chalcopyrite in quartz veins and adjacent silicified zones. The mineralization is developed within variably altered mafic to intermediate intrusive rocks of the Early Proterozoic Rex Lake Plutonic Complex (RLPC) that underpins the Jean Lake property. The B1 pegmatite is also hosted by the RLPC within structures trending at approximately 270o-290o. Of interest is the occurrence of 2.46 g/t Au over 3.70m from 41.30m-45m in FM23-01A. This intersection occurs in a shear zone at or near the base of the B1 pegmatite in fine grained gabbro. The gold is associated with quartz veins and arsenopyrite
HISTORY OF GOLD IN THE AREA
Historically, 5.5 million ounces of gold has been produced as a by-product of base metal copper-zinc massive sulphide type deposit production in addition to major gold deposits such as the New Britannia, Puffy Lake, and Tartan deposits, with cumulative production of more than 1.5 million ounces of gold in the Flin Flon-Snow Lake greenstone belt. In 1940, two bulk samples of mineralization weighing 22.7 and 22.2 kg. respectively, were sent to the Canada Department of Mines and Resources in Ottawa for testing from what was known as the Sparky Gold Property at the time (the current Jean Lake Property). The first bulk sample contained 16.46 g/t gold and 2.39 g/t silver, and the second bulk sample contained 241.71 g/t gold and 12.34 g/t silver. Gold exploration continued unabated in the area with high-grade gold mineralization documented from numerous past producing gold mines and properties hosting significant gold mineralization.

The proximity of these gold properties to our Jean Lake Property is illustrated in the map below in Figure 4, and Table 2 which summarizes historic gold and lithium abundances in the immediate area.

CURRENT GOLD PRODUCTION IN SNOW LAKE
Current gold production is ongoing in the Snow Lake area. In 2022 Hudbay Minerals Inc (current market cap of $C1.7Bill) re-opened the Lalor Mine in Snow Lake, MB, announcing that it estimates 33% of its overall revenue will now be generated from gold and silver, up significantly from 18% in 2019. Hudbay Minerals’ current mineral reserve estimates in Snow Lake total 18 million tons with approximately 2.1 million ounces in contained gold, and the expected mine life of the Snow Lake operations to be maintained and extend until 2038. Hudbay’s annual gold production from Snow Lake is expected to average more than 190,000 ounces over the next three years. The Flin Flon-Snow Lake belt is currently active with other mineral companies exploring for gold including QMX Gold Corporation, Kinross Gold, Callinex and Rockcliff Metals Corp.
The 2023 exploration program will begin later in 2023 on the B1-B2 spodumene bearing pegmatite. The lateral extent of the spodumene mineralization along strike between the zone and the east end of the dyke at B2 and to the west is poorly understood, due to overburden cover. An excavator will be used to strip overburden from outcrop and expose the pegmatite to the east and west before further drilling is attempted.
Foremost intends to continue exploration for spodumene-bearing pegmatite and additional gold mineralization on the Jean Lake property. A field crew will begin prospecting and rock and MMI soil geochemical surveys. Lidar survey results will underpin these surveys.
