Winnipeg, Manitoba--(Newsfile Corp. - February 21, 2024) - Snow Lake Resources Ltd., d/b/a Snow Lake Energy (NASDAQ: LITM) ("Snow Lake" or the "Company") is pleased to announce that it has begun its transition into a diverse clean energy company with the acquisition of up to an 85% interest in the Engo Valley Uranium Project located in Namibia (the "Engo Valley Uranium Project").

CEO Remarks

"We believe the opportunity to acquire this interest in the Engo Valley Uranium Project fits well with our strategy of expanding our portfolio of clean energy and critical mineral projects, thereby transitioning our company into a diverse clean energy company" commented Frank Wheatley, CEO of Snow Lake. He continued: "With a global focus on clean energy, uranium being a critical mineral, Namibia being one of the best mining jurisdictions in Africa with a long history of uranium exploration, development and production, we feel that the Engo Valley Uranium Project compliments our current portfolio of lithium assets in Manitoba."

"With the uranium market being in a major cyclical uptrend, the acquisition of the Engo Valley Uranium Project provides our shareholders with tremendous upside, particularly with drilling on the project to commence imminently."

"As part of our Company's transition, we are changing our business name from Snow Lake Lithium to Snow Lake Energy, to better reflect our focus on a diverse range of clean energy minerals and resources projects, that will play a key role in the 21^st century's energy transition."

Namibia

Namibia is ranked as the 6^th highest African mining jurisdiction for mining investment according to the Fraser Institute's 2022 annual survey, and was the world's third-largest producer of uranium, accounting for 11% of global production, in 2022⁴. The Husab Uranium Mine and the Rossing Mine are currently the only operating uranium mines in Namibia, with 5 major uranium mines currently in development.

Clean Energy

Nuclear energy is considered to be "clean energy" by the United States and Canadian governments and a source of low-carbon electricity. Three reasons why nuclear is considered to be clean and sustainable include: 1) nuclear energy protects air quality since it is a zero-emission energy source; 2) nuclear energy's land footprint is small and produces more electricity on less land than any other clean-air source; and 3) nuclear fuel produces minimal waste as it is extremely dense⁵.

Uranium and nuclear energy are critical to the clean energy transition and provide reliable, affordable electricity that will help countries achieve low carbon energy security.

Engo Valley Uranium Project

Overview

The Engo Valley Uranium Project is located in the Skeleton Coast, in the Opuwo District of the Kunene Region, along the coast of northwest Namibia, approximately 600 kilometers north of Swakopmund, Namibia (see Figures 1 and 2). Uranium mineralization was discovered in 1973 and exploration was conducted intermittently by Gencor between 1974 and 1980. The Engo Valley Uranium Project is considered to be a top tier exploration project.

The project is accessible from the south via 190km of desert track roads from Mowe Bay, via the Sarusas mine. To the east there are unconfirmed track roads that connect the project area to the settlement of Orupembe.

Exclusive Prospecting License

Exclusive Prospecting License EPL 5887 (the "License") is registered in the name of the Project Company and covers a surface area of approximately 68,283 hectares (See Figure 2). The License was granted for industrial minerals, non-nuclear fuel minerals, nuclear fuel minerals, precious metals and precious stones, which includes uranium.

An environmental clearance certificate was issued by the Namibian Ministry of the Environment to the Project Company for a period of three (3) years and is valid until at least August 15, 2024, permitting exploration work on the License.

Current Uranium Operations in Namibia

Namibia hosts many proven uranium deposits, including 3 major deposits, 2 of which are currently in production:

Rossing Mine: One of the largest open pit uranium mines in the world, operating since 1976, currently producing 3,711 tonnes of uranium oxide per annum; 8% of the global output. By the end of 2021, Rossing had supplied 142,908 tonnes of uranium oxide.

Husab Mine: Swakop Uranium started development of the mine in 2013 and production started at the end of 2016. The main part of the Husab mine is the Rossing South orebody, about 5 kilometers south of the Rossing mine and 45 kilometers north east of Walvis Bay, producing about 5,500 tonnes of uranium oxide per annum.

Langer-Heinrich Mine: One of the largest uranium reserves in Namibia having estimated reserves of 57,000 tonnes of ore grading 0.055% uranium, with the past producing mine currently in process of resuming operations.

Geological Setting- Engo Valley Uranium Project

In the Engo Valley Uranium Project, uranium mineralization occurs in the sedimentary strata of the Karoo Sequence: as an unconformity-related in a fluvio-glacial alluvial fan type deposit in the of the Dwyka Formation and has potential for a roll-front type deposit in the Engo Formation. Uranium mineralization occurs as disseminated carnotite in the clastic sediments of the Dwyka Formation and as fine-grained uraninite in the black shale and the pink sandstone of the Engo Formation. The pink sandstone has not been adequately investigated.

The Munutum and Natas Valley area east of the Engo Valley area also has not been adequately explored. Historical airborne radiometric data indicates the potential for a shallow calcrete-hosted uranium mineralization.

Historical Exploration

Gencor conducted an exploration / reconnaissance program intermittently between 1974 and 1980. The program was comprised of airborne radiometric survey, ground radiometric survey, geological mapping, diamond and percussion drilling, limited resistivity work and limited radon etch survey. A total of 5,784 meters of drilling were completed, including 1,061 meters of diamond drilling.

The airborne radiometric survey was confined to the western side of the License along the Engo Valley paleochannel. The survey delineated four anomalies, named D1, D2, D3 and D4. D1 was further delineated into three anomalies named D1 Extension, Main Uranium Occurrence (MUO), and Louw's Valley.

Most of the historical exploration was focused in D1 and most of the drilling was concentrated in the MUO. The drilling was widespread, non-systematic and non-grid pattern. An untested anomaly, named D5, has not been evaluated for uranium and covers an area of 14 square kilometers with a strike length of 7 kilometers.

A historic, non-compliant S-K 1300 mineral resource estimate was completed by Gencor in the 1970's on the MUO and D1 Extension.

Proposed Work Program

The proposed exploration work program on the Engo Valley Uranium Project will include a review of all historical exploration data, the historical resource estimate, and all previous drilling results, to be followed by fresh twin hole drilling of historical drilling, together with grid infill drilling in order to both test the validity of the MOU and D1 exploration targets and to produce an initial SK-1300 compliant mineral resource estimate. Figure 3 sets out a map of both the historical drill holes, and the currently proposed drill holes, on the Engo Valley Uranium Project.

Agreement to Acquire An 85% Interest in the Engo Valley Uranium Project

Snow Lake and a private British Columbia company (the "Vendor") have entered into a binding letter of intent (the "LOI"), pursuant to which Snow Lake will acquire up to 85% of Namibia Minerals and Investment Holdings (Proprietary) Limited (the "Project Company"), a private Namibian company, which in turn is the sole registered and beneficial owner of 100% of the right, title and interest in the Exclusive Prospecting License - 5887 (the "License") for the Engo Valley Uranium Project, all as more particularly described in Schedule A attached hereto.

Snow Lake will acquire its 85% interest in the Engo Valley Uranium Project in two stages, as follows:

a) First Stage Interest
