• Additional staked claims expand and enhance the Pine Ridge landholding, which now totals approximately 15,130 hectares (37,387 acres)

CEO Remarks

"The expansion of the landholding at Pine Ridge is a strategic step with our joint venture partner Global Uranium and Enrichment Limited to enhance our position in the Powder River Basin" said Frank Wheatley, CEO of Snow Lake. "We look forward to shortly starting the 2025 exploration season at Pine Ridge across this expanded footprint in order to start unlocking the full value of Pine Ridge."

Pine Ridge Uranium Project

The Pine Ridge Uranium Project is an advanced 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 the U.S. primarily via ISR production methods. The Project 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.

Historical drilling conducted by the vendors and prior operators of Pine Ridge, combined with recent geological modelling, highlights the strong potential for further uranium mineralisation in these areas. In particular, updated modelling of redox boundaries suggests a substantial increase in prospective strike length, from approximately 225 km to nearly 435 km as shown in Figure 2.
