Updated flow rate on Rost 1-26 well
Mendell Helium plc announced an updated flow rate for M3 Helium Corporation's Rost 1-26 well, showing a 132% increase to 250 Mcf per day, equating to a potential daily helium value of approximately $3,800 or an annualised revenue of $1.4 million. The well is now flowing gas even without a pump, and M3 Helium will switch to a more economical beam pump. Discussions with partners for further well development in the Fort Dodge region are progressing, and the option to acquire M3 Helium has been extended to February 28, 2026. Disclaimer*

About this update from Mendell Helium Plc
[{"type":"text","content":"\n\n\n \nMendell Helium plc\n \n(\"Mendell Helium\" or the \"Company\")\n \nUpdated flow rate on Rost 1-26 well\n \n \nMendell Helium is pleased to announce an updated flow rate for M3 Helium Corporation's (\"M3 Helium\") Rost 1-26 well (\"Rost\") in Fort Dodge, Kansas. The Company also provides an update on the ongoing development of Rost and the wider Fort Dodge region.\n \nHighlights\n· Flow rate at Rost has been measured at 250 Mcf per day - a 132% increase over the last measured rate in November 2025, equating to a potential value of approximately $3,800 of helium per day or approximately $1.4 million per year\n· Rost is now flowing gas even when the pump is turned off\n· M3 Helium will switch the well onto a beam pump which is more economical to run\n· Discussions with partners to develop further wells in Fort Dodge are moving forward\n \nAs announced on 27 June 2024, the Company has an option (the \"Option\") to acquire M3 Helium, a producer of helium which is based in Kansas and holds an interest in six producing wells. There is no certainty that the Company's option to acquire M3 Helium will be exercised, nor that the enlarged group will successfully complete a re-admission. As announced today, the Company and M3 Helium have agreed to extend the date on which the Option should be exercised to 28 February 2026.\n \nRost\nAs previously announced, since de-watering operations began in September 2025, Rost has continued to increase production volumes. The most recent measured flow rate of 250 Mcf per day represents a 132% increase over the last measured rate in November of 108 Mcf per day.\n \nWith a 5.1% helium composition, current gas production from the well is equivalent to approximately $3,800 of helium per day. If that rate was consistent for a year then Rost would have an annualised helium production revenue of approximately $1.4 million per year. Investors should note that this is an illustration only. The well's flow rate has doubled in each of the past two months and there is some evidence on site (as explained below) of continued strength in the reservoir but, once the well does peak, it is prudent to expect some decline in flow rates.\n \nDuring the...
