Pine Ridge Uranium Project Continues to Deliver Encouraging Exploration Results

Winnipeg, Manitoba--(Newsfile Corp. - October 2, 2025) - Snow Lake Resources Ltd., d/b/a Snow Lake Energy (NASDAQ: LITM) ("Snow Lake"), a uranium exploration and development company, announces that an additional 15 drill holes 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"), delivering encouraging intercepts including 1.8m at 550ppm U₃O₈ and 1.7m at 520ppm U₃O₈.

The Joint Venture has now completed 49 drill holes on Pine Ridge, for a total of 18,239m (59,840 ft) of drilling. The total program of 125 holes, including 38,000m (125,000 ft), is expected to be completed during November 2025_.

Highlights

• Third 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 mineralisation and has returned excellent results, including:

  • 1.8m at 0.055% (550 ppm) U₃O₈ from 258.3m in PR25-041 including:

    • 0.8m at 0.070% (700ppm) U₃O₈ at 258.9m

  • 1.7m at 0.052% (520 ppm) U₃O₈ from 307.2m in PR25-040 including:

    • 0.9m at 0.068% (680 ppm) U₃O₈ from 307.4m

  • 3.8m at 0.035% (350 ppm) U₃O₈ from 220.2m in PR25-045

  • 1.5m at 0.043% (430 ppm) U₃O₈ from 267.8m in PR25-046

  • 1.7m at 0.043% (430 ppm) U₃O₈ from 260.1m in PR25-048

• Recently, the area permitted for drilling was expanded over a key part of Pine Ridge with the approval of a BLM Exploration Permit

• Drilling has confirmed the existence and increased continuity of at least two major sandstone units that appear to be geologically and hydrologically isolated, allowing for future ISR development

• Drilling is ongoing and is expected to continue through to the end of November 2025

CEO Remarks

"We are very pleased with the most recent drill results from the Pine Ridge uranium project, as they continue to yield strong results and assist in defining foll-front mineralization," said Frank Wheatley, CEO of Snow Lake.

"We firmly believe that we are positioning Snow Lake to benefit from a strengthening uranium market, with uranium prices recently exceeding US$80/lb, against the backdrop of U.S. Administration policies designed to support nuclear energy as a critical component in ensuring U.S. national, economic and energy security."

Drill Program

Ongoing results are encouraging as they have confirmed and further defined the original concept of multiple redox boundaries that are hosted by numerous sand horizons. The current drill program has confirmed the existence and increased continuity of at least two major sandstone units within the Tertiary Ft. Union Formation in the eastern flank of Pine Ridge. The units, generally 700 to 1,000 feet deep and 1,100 to 1,300 feet deep, appear to be geologically and hydrologically isolated, allowing for future ISR (in-situ recovery) development.

A total of 24 continuous and correlatable mineralized roll fronts have been identified in the two major sandstone units. In some portions of Pine Ridge, the roll fronts are closely stacked within a unit and with the overlying or underlying unit. As the density of drilling increases during the 2025 program, the details of the geometry of these roll fronts will emerge more strongly. Such information would support the development of an initial inferred mineral resource estimate at Pine Ridge.

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

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. Pine Ridge is surrounded by existing uranium projects held by UEC and Cameco and is also 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.
