Snow Lake Phase 2 Drill Program Underway at Engo Valley

Winnipeg, Manitoba--(Newsfile Corp. - April 16, 2025) - Snow Lake Resources Ltd., d/b/a Snow Lake Energy (NASDAQ:LITM) ("Snow Lake"), a uranium exploration and development company, announces that the Phase 2 drill program at its Engo Valley Uranium Project ("Engo Valley") is now underway.

Highlights

• Phase 2 drill program is now underway

• Drill crews are on site, have established their exploration camp, and the initial drill holes comprising the Phase 2 drill program have now been completed

• Phase 2 is planned to consist of up to 7,500 meters of a combination of reverse circulation and diamond drilling, and is designed to provide a drill database sufficient to calculate a maiden uranium mineral resource estimate in accordance with SK-1300

• Maiden mineral resource estimate is currently scheduled for completion during the second half of 2025

• Phase 2 also includes plans to test a number of additional targets in the north and south parts of the project, outside of the two targets which are the main focus of Phase 2

CEO Remarks

"We have now completed the initial drill holes on our Phase 2 drill program at Engo Valley" said Frank Wheatley, CEO of Snow Lake. "Our objectives for Phase 2 are simple - to complete sufficient drilling to allow us to calculate a maiden resource estimate at Engo Valley during the second half of 2025."

"The global supply deficit of uranium will continue to increase as the world continues to expand it nuclear energy production capacity. With new uranium mines needed to meet this demand, programs like our Phase 2 drill program at Engo Valley are essential to prove up potential new economic sources of primary uranium. With Namibia being the third largest global uranium producer, we look forward to a successful Phase 2 drilling campaign at Engo Valley in Namibia."

Phase 2 Drill Program

The Phase 2 drill program ("Phase 2") has been planned to consist of an aggregate of up to 7,500 meters of a combination of reverse circulation and diamond drill holes in an in-fill grid pattern sufficient to allow the calculation of a maiden mineral resource estimate. Phase 2 will be focused on the Main Uranium Occurrence ("MUO"), and the D1 target area ("D1"). See Figure 1.

A number of drill holes will be undertaken on some of the targets identified by the radon cup survey undertaken in 2024, outside of the MOU and D1. Downhole radiometrics will be conducted on each drill hole.

Assuming the Phase 2 drill program goes according to plan and assay results are received in a timely fashion, the preparation of a maiden mineral resource estimate for Engo Valley is targeted for completion during the second half of 2025.
