VANCOUVER, British Columbia, Aug. 13, 2026 (GLOBE NEWSWIRE) -- REV Exploration Corp. (“ REV ” or the “ Company ”) ( TSXV: REVX; OTC: REVFF; FSE: 7FF ) is pleased to announce the successful completion of a 3D seismic program covering the Company’s West Butte Project in Toole County, Montana. West Butte is REV’s cornerstone Montana asset that captures a significant portion of a geologically continuous Helium system across a regional structural corridor that has produced notable recent discoveries. The property has also never been previously explored for naturally occurring hydrogen.

The 8.5 square mile (22 sq. km) 3D seismic survey at West Butte was carried out by Tetra Tech, the same firm that completed a similar survey this past spring at MAX Power’s (CSE: MAXX) Lawson Natural Hydrogen Discovery. As with Lawson, high-quality data from West Butte was recorded. This data has been delivered for processing and will soon be analyzed and interpreted by the same team that reviewed the Lawson 3D seismic survey. REV’s technical and marketing collaboration with MAX Power began over a year ago, and REV remains one of MAX Power’s largest shareholders with six million shares.

The 3D seismic survey from West Butte is expected to provide REV’s technical team with greatly enhanced subsurface imaging of the structural and stratigraphic targets underlying the Montana acreage, supporting the delineation of upcoming drilling locations.

Mr. Jordan Potts, REV CEO, commented: "The completion of the West Butte 3D seismic program is a major step forward for REV's Montana exploration strategy. Executing a mixed-source survey across the challenging terrain of West Butte required careful planning by our technical team and a skilled field team. We are very pleased with the quality of the data collected and look forward to advancing interpretation to identify our first drilling targets at this very promising project in a known Helium district.”

West Butte 3D Seismic Survey Details

The 3D seismic program covered approximately 8.5 square miles across the northwestern slopes of West Butte, located approximately 14 miles east-northeast of Sunburst, Montana. The survey area encompassed a diverse range of terrain, transitioning from gently rolling cropland on the western edge of the butte through pastureland and coulees on the foothills to the base of the main butte's talus slopes — terrain that required careful operational planning and a flexible field methodology to execute effectively.

The program was designed as a mixed-source wireless node survey, reflecting the diverse topography of the project area. Receiver lines were oriented north-south at 250-meter spacing with a 50-meter receiver interval, and source lines ran east-west at matching 250-meter spacing with a 50-meter source interval. In total, the program recorded 1,524 Vibroseis source points on accessible, gently sloping ground and 269 dynamite shot points in the steeper terrain of the coulees and foothills where Vibroseis access was not feasible. This mixed-source approach was designed to provide full and optimal subsurface illumination across the entire survey area without compromising data quality.

West Butte is situated within a broad regional area highlighted by 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

The regional characterization above is conceptual and interpretive in nature, based on publicly available and Company geological data.

The 3D seismic survey at West Butte was completed with an outstanding safety record - zero injuries and zero accidents throughout all field operations. Surface disturbance was proactively mitigated by the field crew and all impacted areas were restored upon completion. The Company maintained active communication with area landowners and stakeholders throughout the program and acknowledges their cooperation and patience during field operations.
