Mendell’s Bitcoin Treasury Policy On 1 April 2025, Mendell Helium announced that it was working on a feasibility study to use excess methane produced at either M3 Helium's Rost 1-26 well ("Rost") well in Fort Dodge, Kansas or future offset wells in the same area to provide energy for a cryptocurrency/Bitcoin mining operation.  A significant advantage of Fort Dodge is the network of the main roads and communications across the area.  The analysis carried out by Mendell Helium has brought other areas to its attention and, to date, the Company has also examined opportunities for Bitcoin mining in Texas and Nebraska, albeit still at an early stage.    A logical extension of this work, and particularly being mindful of M3 Helium's forthcoming production plans at Rost which, if successful, are expected to be highly cash generative, is to implement a Bitcoin treasury management policy to support the operating activities of M3 Helium.   Mendell has been engaging with consultants and specialist cryptocurrency advisers to formulate a Bitcoin treasury management policy to:   Gavin Burnell, Managing Director said: “We are pleased to back the management of Mendell Helium plc.
