• Snow Lake intercepts high grade lithium in 4 separate pegmatite dykes
• Drilling Results continue to validate resource expansion across the property
• Lithium intercepts confirm growth in future starter pit on SG & Grass River
• Drilling campaign continuing to execute against previously stated objectives

Best Results:

• SGP = 1.84% Li₂O over 6.32 meters (GRP-003)
• TBL = 1.36% Li₂O over 17.97 meters 429.50 meters down hole (TBL-035)
• BYP = 1.50% Li₂O over 7.00 meters (BYP-001)

WINNIPEG, MB / ACCESSWIRE / May 31, 2022 / Snow Lake Resources Ltd., d/b/a Snow Lake Lithium Ltd. (NASDAQ:LITM) ("Snow Lake" or the "Company") a lithium resource company committed to operating the world's first fully electric lithium mine, today is pleased to provide an update on the current drilling campaign at the Snow Lake Lithium project in Northern Manitoba.

Snow Lake's project now contains four identified dykes with high grade lithium intercepts above 1% Li₂O with the TBL and GRP continuing to return positive results (see Table 1). In addition, the Company is happy to report intercepts on the SGP and BYP dykes (see Table 1). Both the SGP and BYP dykes were located and sampled during last fall's prospecting campaign (Dec 06, 2021- Snow Lake Resources Ltd. Samples Up To 6.97 WT% Li2O from its Manitoba Project).

Of note are the deep and wide intersections of TBL-035 (see Table 1) seen at 429.50 m at depth. This could indicate that this pegmatite system may continue much deeper on the project than initially anticipated. Future drilling will test the possible depth extensions of the TBL dyke.

Philip Gross CEO of Snow Lake commented "The results of the 2022 drilling campaign to date continue to impress with regard to expansion and definition. Dale Schultz VP of Resource Development and his team are delivering the necessary validation to expand the resource to our 25-year mine life target and to provide the project with a starter pit at the SG/GRP targets. In parallel, the metallurgical testing, environmental and feasibility studies are all progressing to schedule as we accelerate the project to permitting and ultimately commercial production. Our discussions now are very focused on establishing our position as a vital component in the developing vertically integrated supply chain of the North American EV ecosystem and we will continue to update the market on our progress as it advances."

GRP/SGP Dykes

Geology of the GRP and SGP dyke and host rocks - The GRP dykes crosscut plutonic intrusive rocks of Monzonite composition, exhibiting medium to coarse grained Plagioclase crystals within a fine to medium grained mafic groundmass. Albitic to potassic feldspars occur frequently within the rock. The groundmass consists of amphiboles and occasional biotite. Garnet has been observed in small clusters within rare melanocratic groundmass. The Monzite has been subject to considerable seracitic and hematitic alteration, often resulting in destruction of the original plutonic minerals and gives the rock a "bleached" appearance. Small quartz and granitic Aplite dykes are common.

The GRP pegmatite dykes appear to strike 110° and dip about 60-65^o SSW. The mineralogy of the dykes is typical for lithium bearing pegmatite dykes, and consists of potassic feldspars, quartz, muscovite and to a lesser extent biotite, tourmaline and rare garnets and very rare beryl. The lithium bearing mineral is spodumene, which varies considerably in both grain size and distribution within the dykes. Spodumene crystals can vary in size from 1 cm to over 10+ cm in size. The GRP dykes often exhibit very large spodumene crystals, often ranging in size from 10-15 cm long, and in the case of GRP-003, larger than the NQ core dimensions. The distribution of the crystals within the dyke intersections is sporadic, with some sections containing up to 25 to 30 percent Spodumene, and other sections that are Spodumene poor to barren, suggesting multiple pulses of fluids and crystal mush from the parent granitic magma. The mineralogy and mineral zonation of the dyke(s) will be the subject of further study in the coming months.

TBL/BYP Dykes

Host Rock - The TBL dyke cross cuts rocks of the Missi Group (1.85-1.83 Ga), which are dominantly sedimentary rocks consisting of heterolithic conglomerates, greywackes and sandstones. There are occasional basaltic to andesitic dykes and sills within the assemblage seen in the drill core. The greywackes are typically composed of fine-grained quartz and biotite, while the conglomerate matrix is composed of biotite, actinolite, chlorite and small (2-3 mm) garnets. The mineral assemblage is typical for upper greenschist to lower amphibolite metamorphic facies rocks.

Crystalized Pegmatite - The TBL pegmatite dyke TB-1 strikes 040° and dips about 85° SE, cross cutting the rocks of the Missi Group. The mineralogy of the dyke is typical for Lithium bearing pegmatite dykes, and consists of potassic or albitic feldspars, quartz, muscovite and to a lesser extent biotite, tourmaline and rare garnets and very rare beryl. The lithium bearing mineral is Spodumene, which varies considerably in both grain size and distribution within the dyke. Spodumene crystals can vary in size from 1 cm to over 10+ cm in size. The distribution of the crystals within the dyke intersections is sporadic, with some sections containing up to 25 to 30 percent Spodumene, and other sections that are Spodumene poor to barren, suggesting multiple pulses of fluids and crystal mush from the parent granitic magma. The mineralogy and mineral zonation of the dyke(s) will be the subject of further study in the coming months.

Analytical - Half core samples are sent to the SGS Lakefield laboratory in Ontario for analysis. Core samples are initially crushed to a size of -12.7 mm, then fragmented to 75% passing 2mm and eventually extruded into a 250 g pulp that is pulverized to 85% passing 75 microns. Samples are sodium peroxide fused and run on ICP-AES and/or ICP- MS generating 56 element analyses.
