Exploration Drilling Underway at the Pine Ridge Uranium Project In the Powder River Basin, Wyoming

Winnipeg, Manitoba--(Newsfile Corp. - July 25, 2025) - Snow Lake Resources Ltd., d/b/a Snow Lake Energy (NASDAQ:LITM) ("Snow Lake"), a uranium exploration and development company, announces that its initial exploration drill program is now underway at the Pine Ridge Uranium Project in Wyoming ("Pine Ridge"), a 50/50 joint venture (the "Joint Venture") with Global Uranium and Enrichment Limited ("GUE").

Pine Ridge is located in the Powder River Basin in Wyoming, the most significant area for uranium production in the U.S., primarily via ISR production methods. The Joint Venture's maiden drill program at Pine Ridge, consisting of ~38,000m (125,000ft) of drilling, will focus on testing high priority targets.

Highlights

• Drill permit approval received from Wyoming Department of Environmental Quality (DEQ) for the maiden drill program at the Pine Ridge.

• Pine Ridge is a near-development In-Situ Recovery (ISR) uranium project located in the heart of Wyoming's prolific Powder River Basin and primed for rapid advancement.

• A large and aggressive drill program of ~38,000m (125,000ft) began this week with high priority drill targets identified.

• Pine Ridge is located ~15km from Cameco's Smith Ranch Mill and is surrounded by established uranium projects held by UEC and Cameco.

CEO Remarks

"We are delighted to have begun our drilling campaign at Pine Ridge," said Frank Wheatley, CEO of Snow Lake. "Our Joint Venture team has reviewed all of the historical drilling data for Pine Ridge and has defined a series of high-priority drill targets. The current drill campaign contemplates up to 38,000 meters of drilling designed to establish a data base sufficient to calculate a maiden mineral resource estimate prior to the end of 2025."

"As we continue to note, the U.S. needs new uranium mines. We are excited to begin our drill program at Pine Ridge, which we feel has all the characteristics of a leading U.S based uranium development project that holds the potential to positively contribute to satisfying the U.S. goals of increasing domestic production of uranium."

Pine Ridge Uranium Project - Overview

Pine Ridge is a near development In-Situ Recovery (ISR) uranium 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 licensed capacity of 5.5Mlbs U3O8 p.a. The Smith Ranch mill is one of the largest uranium production facilities in the U.S.

Exploration Program Overview

The Drilling Permit has been received from Wyoming DEQ and the drill program has begun. Single Water Services LLC will conduct the drilling program and has successfully completed numerous previous drilling campaigns at Pine Ridge. Their familiarity is expected to support an efficient and well executed program, with the potential addition of a second rig to accelerate progress. A contract has also been signed with Hawkins CBM Logging, Inc. from Cody, Wyoming. Hawkins has undertaken a significant amount of geophysical probing in the Powder River Basin.

Bryan Soliz, owner of SOLA Project Services, has been contracted by the Joint Venture and is leading the geologic and mineralization modeling and is correlating uranium roll fronts among multiple sandstone packages. Mr. Soliz has significant experience and expertise in the region, highlighted by more than 25 years of exploration and production experience in the Powder River Basin, including at the adjacent Smith Ranch project operated by Cameco.

The geologic modeling has guided the identification of high-priority drill targets in the area (shown below in red) with approximately 38,000m (125,000 ft) of drilling to be completed inside these areas during the initial exploration program.
