Mendell Helium is pleased to announce that M3 Helium Corp. (“M3 Helium”) has signed two further leases for land in Fort Dodge, Kansas that it considers to be prospective for helium production.

The Durler and Leffert leases are located very close to M3 Helium’s existing Bleumer and Enlow leases, around four miles from the Rost 1-26 and Rost 2-26 well sites, and were obtained for a modest cash consideration. Adding to M3 Helium’s land holdings in Fort Dodge is consistent with the strategy set out in the Company’s announcement of its fundraising on 30 April 2026, namely to accelerate the development of its production plans in Fort Dodge. As with the other leases, Mendell Helium believes that each of the Durler and Leffert leases could potentially accommodate two production wells.

Nick Tulloch, Chief Executive Officer of Mendell Helium and Chairman of M3 Helium, said: Since raising £5 million in an institution-led fundraise, we have moved quickly to put preparations in place for our forthcoming expansion of Fort Dodge. The Durler and Leffert leases are strategically located near M3 Helium’s existing land holdings which, in time, may enable M3 Helium to achieve some cost savings in its development plans by combining production facilities and access to disposal wells.”
