Snow Lake Lithium Signs MOU with Epiroc Canada Inc., Announces Operational Update from its Drilling Campaign Including a High-Grade Intercept of 1.53% Li2O over 24.94 Meters

Best Results:

• 1.53% Li₂O over 24.94 meters at 193.5 meters down hole (TBL-038)

WINNIPEG, MB / ACCESSWIRE / June 21, 2022 / Snow Lake Resources Ltd., d/b/a Snow Lake Lithium Ltd. (NASDAQ:LITM) ("Snow Lake" or the "Company"), today announced that the Company has signed a Memorandum of Understanding (MOU) with Epiroc Canada Inc. (Epiroc) for Epiroc to assist with the technical and commerical design of the world's first fully electric lithium mine at the Company's Snow Lake Lithium^TM project in Manitoba, Canada. In addition, the Company provided an update on its ongoing drilling campaign and the continued interception of high-grade results from the Thompson Brother (TBL) dyke.

As part of its collaboration with the Company, Epiroc will contribute to the review of site planning and design for Snow Lake's planned fully electric lithium mine and will give technical and engineering advice for the project's overall development. Epiroc has a long history of offering innovative and safe equipment, as well as automation, digitalization, and electrification solutions to the industry. Epiroc has exhibited a remarkable aptitude in project coordination and vertical integration, as seen by its recent achievement in the Borden Mine project in Chapleau, Canada, which is the first all-electric gold mine in the world.

"The MOU with Epiroc is a significant step forward in Snow Lake's goal of commercial lithium production, as it allows the two companies to form a synergistic partnership that will draw on years of deep industry experience and technological understanding," said Philip Gross, CEO and Chairman of Snow Lake. "We look forward to collaborating with Epiroc and advancing Snow Lake's role as an integral component of the North American EV ecosystem."

Jason Smith, Integration Manager of Epiroc North America commented, "Epiroc is looking forward to collaborating with Snow Lake Lithium to help develop and execute an all-electric mining operation. Our partnership's purpose is to support the Company's environmental activities while also increasing operational efficiency at all phases of the mine's development. We are excited to build on what we can offer with our Meglab competencies coupled with the Epiroc equipment technology and operational presence within the region. We see this as a great opportunity to play our part to position Snow Lake as the cleanest lithium supplier for the North American EV and battery markets."

The MOU collaboration comes in tandem with the recent drill results that have been intercepted at the Thompson Brothers Lithium (TBL) dyke and Sherritt Gordon (SG) dyke. The TBL dyke continues to return high grade lithium intercept of 1.53% Li₂O over 24.94 meters from hole TBL-038. Drilling at the SG Dyke returned narrow intercepts of 1.14% Li₂O over 1.35 meters and 0.92 Li₂O over 2.95 meters from SPG-003 (Table 1, Figure 1, and Figure 2).

TBL-038 represents an infill hole into the TBL resource block with the purpose of confirming continuity of the TBL deposit and solidifying the future resource modeling. The TBL-038 hole will also be used as part of the ongoing metallurgical test work being conducted by SGS Lakefield.

Dale Shultz, Snow Lake's Project Manager and VP of Resource Development, commented "With the high-grade intercepts we have received across our TBL and SG dykes, the Company is looking forward to completing the requisite validation for resource expansion and definition. We will test and assess the drill intercepts we have collected to-date for mineral resource continuity, which we will use in our analysis to ensure geology and grade quality. We are excited to continue our ongoing drilling program and to report back to the market on the results we obtain in the coming months."

The Snow Lake Lithium^TM property encompasses several lithium-rich spodumene pegmatite dykes which tend to form in clusters. The presently known dykes are found on the east and west sides of a body of water known as Crowduck Bay in Manitoba, Canada, which is joined to Wekusko Lake to the South West. There are two known pegmatites on the east side of a narrow part of the southern end of Crowduck Bay which are called the Thompson Brothers Lithium dyke (TBL), and the Brian Youngs Pegmatite dyke (BYP). The TBL dyke contains an S-K 1300 compliant resource estimate dated June 9, 2021 of an Indicated Resource of 9,082,600 tonnes of lithium bearing ore grading 1.00% Li2O, and an Inferred Resource of 1,967,900 tonnes of lithium bearing ore grading 0.98% Li2O. On the west side of Crowduck bay are two recently drill tested dykes known as the Sherritt Gordon dyke (SG) and the Grass River Pegmatite dyke (GRP), which recently drill tested an intercept of 3.35% Li2O. Although originally considered as unique geological events, the Company now believes these dykes to be one large cluster of pegmatites that could provide an ideal starter pit using an open pit mining method. It is the Company's vision to build this resource to a 25-year mine life initially utilizing an open pit and progressing to an underground mining scenario.

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 giving the rock a "bleached" appearance. Small quartz and granitic Aplite dykes are common.

The GRP and SGP 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.

The TBL Dyke

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 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 ran on ICP-AES and/or ICP- MS generating 56 element suit.
