Snow Lake Receives Positive Preliminary Results from the Engo Valley Phase 2 Drill Program

June 18, 2025 at 07:00 AM EDT

Winnipeg, Manitoba--(Newsfile Corp. - June 18, 2025) - Snow Lake Resources Ltd., d/b/a Snow Lake Energy (NASDAQ: LITM) ("Snow Lake"), a uranium exploration and development company, announces that it has received some positive initial results from the Phase 2 drill program at the Engo Valley Uranium Project ("Engo Valley").

Highlights

First segment of the Phase 2 drill program is now complete

A total of 31 reverse circulation (RC) drill holes completed for a total of 2,719 meters

8 out of the 31 RC drill holes in the first segment returned mineralized intersections greater than 100 ppm eU₃O₈, ranging from 1 meter to 20 meters in width

Samples from each drill hole have been sent for chemical assays and results are pending

Phase 2 drill program 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 before the end of 2025

CEO Remarks

"We continue to make steady progress on our Phase 2 drill program at Engo Valley. Initial results from the RC portion of the drilling program have produced good intercepts of uranium mineralization," said Frank Wheatley, CEO of Snow Lake. "As we being the diamond drilling segment of the Phase 2 drill program, we remain on schedule to complete a maiden resource estimate for Engo Valley by year end."

"As the global supply deficit of uranium expands, new uranium mines will be required to meet increasing demand. With Namibia being the world's third largest uranium producer, exploring and developing prospective projects like Engo Valley is essential to identifying and proving up potential new economic sources of primary uranium."

Update - Phase 2 Drill Program

A total of 21 infill RC holes have been completed in the MUO, 6 infill RC holes within the D1 North area, and 4 RC holes were completed in the MUO-D1 area.

Downhole radiometrics were completed on each drill hole with a gamma spectrometer probe. The reader is cautioned that Snow Lake uses eU₃O₈ calculations as a preliminary indication for chemical grades that have yet to be confirmed by chemical assays. Snow Lake considers all eU₃O₈ readings below 50 ppm as background radioactivity, and not mineralised ground.

Notable results from the downhole radiometrics on the first segment of drilling include:

Mineralized intersection of 997 ppm eU₃O₈over a 7 m interval, associated with shale, observed from drill hole ERCH025

Mineralized intersection of 296 ppm eU₃O₈over a 1.2m interval, associated with shale, observed from drill hole ERCH026

Selection and preparation of samples for wet chemical analysis is in progress. Samples will be submitted to ALS laboratories. Analysis of data from the Phase 1 drill program samples did confirm that radiometric grades are reliable and can be used as equivalent radiometric grades. Sampling is undertaken on each meter interval. Selective sampling of drill holes using downhole radiometric grades has been carried out based on this outcome.

The diamond drilling segment of the Phase 2 drill program is scheduled to start during the week of June 15, 2025. A total of 19 diamond drill holes are planned for the MUO and 8 diamond drill holes are planned to be drilled in the D1 area.

The objective of the Phase 2 drill program is to develop a drill data base sufficient to calculate a maiden mineral resource estimate for Engo Valley by the end of 2025. Phase 2 is focused on the MUO, and the D1 target area. See Figure 1.

Assuming the Phase 2 drill program continues to go 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 before the end of 2025.
