REV Exploration Commences 3D Seismic Program at Montana Helium Project Ahead of First-Ever Drilling

REV Exploration has commenced a 26.75-kilometre 3D seismic survey at its West Butte Helium Project in Montana, marking a significant step toward the project's first-ever drilling campaign. 

The seismic program is being conducted by Tetra Tech, the same firm that recently completed a similar survey for MAX Power’s Lawson Natural Hydrogen Discovery in Saskatchewan. REV intends to use the survey results to refine drill targets and advance the project toward a summer drilling program. 

West Butte is positioned within a broader regional helium system that REV believes contains the key geological ingredients associated with helium accumulation, including deep basement-sourced helium charge, fault-controlled migration pathways, extensive Cambrian and Devonian reservoir intervals, and multiple structural trapping opportunities. 

According to the company, the project lies along the same prospective structural corridor that hosts recent nearby helium discoveries. REV’s technical team, which was also involved in the Lawson natural hydrogen discovery, believes the broader Montana region remains underexplored for both helium and natural hydrogen potential. 

The 3D seismic survey is designed to image deep basement structures and fault systems, confirm structural closures, evaluate reservoir continuity, identify potential helium traps, and assess areas that may also be prospective for natural hydrogen accumulations. 

Management emphasized that West Butte is only one component of a larger regional strategy. In addition to its Montana assets, REV controls the drill-ready Aden Dome project along the Alberta-Montana border and continues evaluating additional helium and natural hydrogen opportunities across the Northern Great Plains and southern Alberta.

VANCOUVER, British Columbia – June 17, 2026: REV Exploration Corp. ("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:

Basement-sourced Helium charge across a regional structural corridor
Fault-controlled migration pathways tied to deep-seated lineaments
Laterally extensive Cambrian and Devonian reservoir intervals
Multiple structural closures capable of hosting stacked accumulations
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:

Image basement structures and fault systems critical to Helium charge

• Confirm closure in the deep section in which detailed shallow mapping has divulged several potential drilling opportunities
• Define structural closures capable of trapping Helium accumulations
• Confirm reservoir presence and continuity across the project
• Identify areas prospective for accumulations of Natural Hydrogen
• Rapidly advance West Butte toward drill-ready status across multiple targets for this summer

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.
