Snow Lake Completes Highly Successful Drill Program at the Pine Ridge Uranium Project in Wyoming

Snow Lake Resources Ltd., dba Snow Lake Energy (NASDAQ: LITM) ("Snow Lake"), a nuclear fuel cycle company, announces that it has received the final set of drill results from an additional 21 drill holes (out of a total of 114 holes) that have been completed on the Pine Ridge Uranium Project ("Pine Ridge"), located in the prolific Powder River Basin in Wyoming, a 5050 joint venture (the "Joint Venture") with Global Uranium and Enrichment Limited ("GUE").

This successful drill program confirmed the presence of widespread uranium mineralization at Pine Ridge, while testing only a very small percentage of the large land package, and established the continuity of mineralization in multiple areas and identified at least 25 mineralized roll fronts contained within three major sandstone packages.

Highlights

• Final 2025 program drill results continue to highlight multiple zones of mineralization at Pine Ridge

• Highly successful drill program was completed with 114 holes and 38,000m (125,000 ft)

• Drilling results have continued to define roll front mineralization and have increased the number of mineralized horizons. New results include:

  • 1.2m at 0.040% (400 ppm) U₃O₈ from 173.7m in PR25-103 and:

    • 0.8m at 0.045% (450 ppm) U₃O₈ from 176.0m

  • 0.9m at 0.041% (410 ppm) U₃O₈ from 194.2m in PR25-102 and:

    • 1.1m at 0.029% (290 ppm) U₃O₈ from 196.3m

  • 1.2m at 0.032% (320 ppm) U₃O₈ from 254.7 in PR25-105

  • 1.4m at 0.026% (260 ppm) U₃O₈ from 257.6m in PR25-106

• Best results from the drill program include:

• 2.6m at 0.101% (1,010 ppm) U₃O₈ from 257.6m in PR25-093 including

  • 2.0m at 0.124% (1,240ppm) U₃O₈ at 257.9m

• 2.0m at 0.092% (920 ppm) U₃O₈ from 314.8m in PR25-017, including

  • 1.2m at 0.132% (1,320 ppm) U₃O₈ from 315.0m

• 3.5m at 0.054% (540 ppm) U₃O₈ from 321.3m in PR25-031, including

  • 1.1m at 0.078% (780 ppm) U₃O₈ from 321.4m

Snow Lake CEO Remarks

"We are extremely pleased with the results of our 2025 drill program," said Frank Wheatley, CEO of Snow Lake. "Pine Ridge is a very large land package in the heart of U.S. domestic uranium production and has demonstrated widespread and continuous uranium mineralization across multiple sand packages. Having only test a small portion of Pine Ridge, we will now analyze the results of our 2025 drill program with a view to planning the next significant drill program." Mr. Wheatley continued.

Drill Program

The latest results from the Pine Ridge drill program further illustrate the continuous nature of the stacked roll fronts noted in previous press releases. The mineralization is hosted in at least two major sandstone units within the Tertiary Ft. Union Formation in the eastern and southwestern portions of Pine Ridge. The sandstone units, generally 200m to 300m deep, and 335m to 400m deep, appear to be geologically and hydrologically isolated, allowing for future ISR development.

Importantly, the mineralization that has been intersected in the southwest portion of the project appears to be hosted in a stratigraphically lower sandstone package than the mineralization hosted by the two sand packages on the eastern portion of the project area. This suggests additional areas and horizons for exploration efforts.

Drill Results

Drilling reported in the most recent area drilled (Figure 1 above) has further supported this geologic interpretation while returning the most significant assay results to date with the previously reported 2.6m at 0.101% (1,010 ppm) U₃O₈ from 257.6m including 2.0m at 0.124% (1,240 ppm) U₃O₈ at 257.9m in PR25-093.

New results from this area are highlighted by PR25-103 with 1.2m at 0.040% (400 ppm) U₃O₈ from 173.7m and PR25-105 with 1.2m at 0.032% (320 ppm) U₃O₈ from 254.7m.

Details of the drill results and drill collars are set out in Schedule A.

Pine Ridge Uranium Project - Overview

Pine Ridge is an In-Situ Recovery (ISR) uranium exploration project located in the southwestern Powder River Basin of Wyoming, the premier U.S. uranium basin. The Project is surrounded by existing uranium projects held by UEC and Cameco and is located only ~15km from Cameco's Smith Ranch Mill, which has a licensed capacity of 5.5Mlbs U₃O₈ p.a. The Smith Ranch mill is one of the largest uranium production facilities in the U.S.
