Highlights:

• Identified previously unseen lineaments and achieved a more precise imaging of the size and scale of hydrogen source areas in the Mid-Continent Rift. 

• Findings suggest a potential for increased hydrogen accumulation. 

Vancouver, British Columbia – August 22, 2024 – TheNewswire: Longhorn Exploration Corp. (TSX-V: LEX) (the “Company” or “Longhorn”) is pleased to announce the successful completion of the reprocessing and interpretation of aeromagnetic and gravity data over the Lily Rock prospect in Kansas, USA, a key area within the Mid-Continent Rift (MCR) (see Figure 1 below). This advanced structural geophysical work has provided an unprecedented view of the geological structures and anomaly sources, delivering critical insights into the hydrogen potential of the region.

Utilizing state-of-the-art 3D imaging techniques, the reprocessing of aeromagnetic and gravity data has significantly enhanced the structural details and distribution of anomaly sources beneath the Lily Rock prospect area. These advanced methods have unveiled previously unseen structures, offering new perspectives on the potential size and scale of hydrogen source areas within the MCR.

The integration of gravity and aeromagnetic data has also revealed encouraging information about potential migration pathways into the Lily Rock prospect area. These findings suggest a promising potential for increased hydrogen accumulation, reinforcing the prospect’s significance in Longhorn’s exploration strategy.

“We are excited about the implications of these findings,” said Cat Campbell, Exploration Geologist and technical advisor to Longhorn Exploration and PureWave Hydrogen Corp.  “The improved resolution and new insights into the geological structures at Lily Rock significantly advance our understanding of the Mid-Continent Rift’s hydrogen potential. This work represents a critical step forward in our ongoing exploration efforts.”

Longhorn remains committed to leveraging advanced geophysical techniques to unlock the full potential of the Mid-Continent Rift, with the Lily Rock prospect continuing to be a focal point of the Company’s exploration activities.

About the Lily Rock Hydrogen Project

The Lily Rock Hydrogen Project is located in eastern Kansas, USA. The Lily Rock prospects sit on the southeast side of the crest of a mapped four-way dip basement closure that itself sits upthrown along the major north-east to south-west trending Nemaha Ridge. The leases are in Wabaunsee County and within an area geologically contiguous with the Sue Duroche #2 well which has a reported test with a hydrogen content of over 90%2. The Company’s prospect area, located in fault-bounded structures adjacent to the Humbolt Fault, is significant. It sits within the Mid-Continent Rift Zone, where Paleozoic reservoirs, closely associated with hydrogen generation and migration, are concentrated, making it an attractive site for further investigation. It is the fractured basement that is the current focus of the Company’s exploration efforts and where the assessed volumes of prospective resources are located.

About PureWave Hydrogen Corp.

PureWave Hydrogen Corp. is dedicated to the exploration and development of naturally occurring hydrogen resources. With a focus on innovative technologies and sustainable practices, PureWave aims to be a leader in the green energy sector, providing clean and renewable hydrogen solutions.

About Longhorn Exploration Corp.

Longhorn Exploration Corp. has the exclusive right and option to acquire PureWave Hydrogen’s rights and obligations under four lease agreements, located in Kansas, USA, known as the “Lily Rock Hydrogen Project”, which allow for the prospecting, exploration, drilling and production of any substance including hydrogen gas. The Company also has an option to acquire a 100% interest and title to the Fame property located in the Clinton Mining Division, British Columbia.
