Pine Ridge Uranium Project Continues to Deliver

Excellent Drill Results

Winnipeg, Manitoba, December 15, 2025 - Snow Lake Resources Ltd., d/b/a Snow Lake Energy (Nasdaq: LITM) ("Snow Lake"), a nuclear fuel cycle company, announces that it has received the next set of drill results from an additional 45 drill holes (out of a total of 93 holes) that have been completed on the Pine Ridge Uranium Project ("Pine Ridge"), located in the prolific Powder River Basin in Wyoming, a 50/50 joint venture (the "Joint Venture") with Global Uranium and Enrichment Limited ("GUE").

Highlights

- Fourth set of drill results continue to demonstrate the strong development opportunity at the Pine Ridge Uranium Project in the Powder River Basin, Wyoming

- Drilling continues to focus on defining roll front mineralization and has returned excellent results, including:

  - 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

  - 2.6m at 0.048% (480 ppm) U3O8 from 260.3m in PR25-080 and:

    - 1.2m at 0.079% (790 ppm) U3O8 from 292.3m

  - 4.1m at 0.030% (300 ppm) U3O8 from 337.3m in PR25-067

  - 0.8m at 0.117% (1,170 ppm) U3O8 from 249.3m in PR25-079

    - 2.4m at 0.030% (300 ppm) U3O8 from 323.5m in PR25-051 and

    - 2.0m at 0.047% (470 ppm) U3O8 from 328.7m including:

    - 0.9m at 0.063% (630 ppm) U3O8 from 329.5m

  - 1.7m at 0.045% (450 ppm) U3O8 from 333.3m in PR25-062

- Drilling program has just been completed with a total of 114 holes over 38,000m (125,000 ft). The final set of drill results will be announced shortly.

Snow Lake CEO Remarks

"We continue to receive positive drill results from our Pine Ridge uranium project as we wrap up our drill program for 2025," said Frank Wheatley, CEO of Snow Lake. "Pine Ridge is a very large project with large unexplored areas, and we have merely scratched the surface of Pine Ridge with this drill program. Drill results to date give us good reason to continue our work at Pine Ridge as we await the final set of drill results from this program.

We see Pine Ridge as a key asset in developing our U.S. focused capabilities across the front end of the nuclear fuel cycle, directly aligning with the U.S. Administration's policies underpinning the development of a domestic nuclear industry to enhance and ensure U.S. national, economic and energy security," Mr. Wheatley continued.

Drill Program

Recent 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 flank of Pine Ridge. The units, generally 200m to 300m deep and 335m to 400m deep, appear to be geologically and hydrologically isolated, allowing for future ISR development.

Drill results in the new area shown in Inset 2 (Figure 2 above) has further supported this geologic interpretation while returning the most significant assay results to data with 2.6m at 0.101% (1,010 ppm) U3O8 from 257.6m including 2.0m at 0.124% (1,240ppm) U3O8 at 257.9m in PR25-093. The sandstones that host this interval may be the same sandstones that host the mineralization drilled earlier this year on the eastern edge of the project.

Details of 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.
