Exploration Program for the Flagship Pine Ridge Uranium Project In Wyoming's Prolific Powder River Basin

Priority Targets Identified, ~38,000m Drill Program Anticipated to Start in July 2025

Winnipeg, Manitoba--(Newsfile Corp. - May 15, 2025) - Snow Lake Resources Ltd., d/b/a Snow Lake Energy (NASDAQ:LITM) ("Snow Lake"), a uranium exploration and development company, announces that an exploration program for the Pine Ridge Uranium Project ("Pine Ridge") in the Powder River Basis in Wyoming, held by Snow Lake and Global Uranium and Enrichment Limited ("GUE") in a 50 / 50 joint venture (the "Joint Venture"), has been developed.

Highlights

• Pine Ridge is an In-Situ Recovery (ISR) uranium project located in the Powder River Basin, Wyoming and primed for accelerated development

• Powder River Basin, Wyoming is the leading uranium-producing region in the U.S., supported by a favourable regulatory environment and streamlined permitting processes

• Utilising the existing 1,214 drill holes on Pine Ridge, the Joint Venture team is developing a complete geological model (that includes 335 km of redox boundaries), and has developed a detailed exploration program to rapidly advance Pine Ridge

• Drill program is expected to start in July 2025, will focus on numerous target areas, and will be comprised of ~38,000m (125,000 ft) of drilling

CEO Remarks

"The potential for Pine Ridge to become a tier-one uranium asset in the United States is precisely the reason why we entered into the 50/50 joint venture with Global Uranium and Enrichment Limited (GUE)" said Frank Wheatley, CEO of Snow Lake. "The tireless work by GUE over the past 12 months to secure Pine Ridge, and to dramatically expand the project footprint, sets the stage for the initiation of a maiden drill program by our joint venture at Pine Ridge."

Overview - Pine Ridge Exploration Program

The Joint Venture has consolidated the existing historical data on the project area and integrated it with available public information from nearby projects to develop a 3D model of the known mineralization and potential mineralisation. The results of this data compilation and evaluation led to the staking of an additional 937 claims at Pine Ridge, and increasing the Joint Venture's landholding, to a total of approximately 15,130 ha (37,387 acres).

In addition, the understanding and results from the data compilation and geological review have guided the prioritisation of drill targets in the area (shown in red below), with approximately 38,000m (125,000 ft) of drilling to be completed inside these areas during the initial exploration program.

Historically, Conoco drilled 765 holes, and Stakeholder Energy drilled an additional 449 holes, into the project area. Their drill campaigns were primarily designed to continue building on the geologic understanding of the project while testing key areas for uranium potential. The results from these drill campaigns allowed Stakeholder to develop a model that included 335 km of redox boundaries hosted in stacked horizons within the Tertiary sandstones. This interpretation is further supported by adjacent, ISR properties with published resources.

Geologists for the previous vendors of Pine Ridge measured 350 sandstone outcrops on the south and west sides of the project area under the direction of Dr. Kent Sundell, Geology Professor Emeritus at Casper College. The purpose of the exercise was to better understand the geologic characteristics of the stacked sandstones and the paleo-river system that deposited the sands.

SOLA Project Services will be contracted by the Joint Venture to provide technical and project support. A principal with SOLA, Mr. Bryan Soliz, has significant experience and expertise in the region, highlighted by more than 25 years of exploration and production work in the Powder River Basin, including at the adjacent Smith Ranch project operated by Cameco. The selection of drill contractors and geophysical contractors is currently underway. Permit approvals are expected in late June and the drill program will commence shortly after the permit is received.

Overview - Pine Ridge

Pine Ridge is an In-Situ Recovery (ISR) uranium project located in the southwestern Powder River Basin of Wyoming, the premier U.S. uranium basin. Historically, the Powder River Basin is the most significant area for uranium production in U.S. via ISR production methods.

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.

Pine Ridge is a uranium project of potential significant scale with a large JORC 2012 exploration target. For more information on this exploration target, please refer to GUE's website¹. Pine Ridge has been significantly de-risked through historic drilling and has an ideal geological foundation to be developed into a production asset.
