(“REV” or the “Company”) (TSXV: REVX; OTC: REVFF; FSE: 7FF) is pleased to announce it has commenced a 26.75 km 3D Seismic Survey over its West Butte Helium Project, to be followed soon thereafter by a comprehensive first-ever drill program. The 3D Seismic Survey at West Butte is being carried out by Tetra Tech, the same firm that completed a similar survey recently at MAX Power’s (CSE: MAXX) Lawson Natural Hydrogen Discovery. REV’s Montana portfolio, led by cornerstone asset West Butte, captures a significant portion of a geologically continuous Helium system characterized by: <ul type="square"><li style="margin-bottom:8pt;">Basement-sourced Helium charge across a regional structural corridor</li><li style="margin-bottom:8pt;">Fault-controlled migration pathways tied to deep-seated lineaments</li><li style="margin-bottom:8pt;">Laterally extensive Cambrian and Devonian reservoir intervals</li><li style="margin-bottom:8pt;">Multiple structural closures capable of hosting stacked accumulations</li></ul> West Butte is interpreted to lie along the same prospective structural corridor that hosts recent nearby Helium discoveries. REV’s geological team, the same team responsible for the Lawson Discovery in Saskatchewan, believes Montana has been under-explored for both its Helium and Natural Hydrogen potential. The seismic program now in progress at West Butte is expected to: <ul type="square"><li style="text-align:justify;">Image basement structures and fault systems critical to Helium charge</li><li style="text-align:justify;">Confirm closure in the deep section in which detailed shallow mapping has divulged several potential drilling opportunities</li><li style="text-align:justify;">Define structural closures capable of trapping Helium accumulations</li><li style="text-align:justify;">Confirm reservoir presence and continuity across the project</li><li style="text-align:justify;">Identify areas prospective for accumulations of Natural Hydrogen</li><li style="text-align:justify;">Rapidly advance West Butte toward drill-ready status across multiple targets for this summer</li></ul> Mr. Jordan Potts, REV CEO, commented: “What makes this opportunity at West Butte truly compelling is the combination of proven discovery success nearby and the scale of the geological system we now control, not just at West Butte but elsewhere in Montana and just across the border in southern Alberta on the same trend. This is not a single prospect story - this is a district-scale opportunity with multiple high-impact drilling and discovery opportunities.” In addition to its Montana portfolio, and the Aden Dome along the Alberta-Montana border, REV continues to evaluate potential new acquisitions of advanced exploration plays in the Helium and Natural Hydrogen sectors in America’s Northern Great Plains and the southernmost areas of Alberta and Saskatchewan near the U.S. border.
