“We are delighted to begin trading on AIM today. As we advance our significant development programme in Fort Dodge, Kansas, this marks the right moment to join a globally recognised growth market that aligns with our long-term ambitions.

“We are supported by an exceptionally committed and talented team, and while there is considerable work ahead as we execute our plans, the foundations for growth are firmly in place. The success of the Rost 1-26 well has validated our strategy, and our extensive land position provides a strong platform from which to expand our operations.

“I would like to thank our shareholders and advisers for their continued support and confidence in Mendell Helium. As we enter this exciting new phase of growth, we look forward to keeping the market updated as our programme of new wells progresses over the coming months.”
