Update on Fort Dodge and Nebraska operations
Mendell Helium plc (the "Company") provided an update on its Fort Dodge, Kansas and Nebraska operations. In Kansas, de-watering preparations for the Rost 1-26 well are progressing, with operations expected to begin in early September 2025. Helium purity is expected to be around 75%, with a Bauer compressor for loading tube trailers arriving mid-September. The Rost well's helium composition is 5.1%, and M3 Helium is assessing the economic viability of selling a 5% helium mix before the PSA unit is connected. In Nebraska, operations at the Jasper well commenced, with drilling expected to finish by the end of August 2025. This well, costing under US$100,000, may support a future Bitcoin mining project due to its proximity to a fiber optic cable. The option to acquire M3 Helium has been extended to September 30, 2025.

About this update from Mendell Helium Plc
[{"type":"text","content":"\n\n\n \nMendell Helium plc\n \n(\"Mendell Helium\" or the \"Company\")\n \nUpdate on Fort Dodge and Nebraska operations\n \nMendell Helium is pleased to provide an update on M3 Helium Corporation's (\"M3 Helium\") Rost 1-26 well in Fort Dodge, Kansas (\"Rost\") and the Jasper well in Nebraska.\n \nHighlights\n· Rost Well, Kansas: Preparations for de-watering are progressing, with first operations expected to commence in early September 2025.\n· Jasper Well, Nebraska: Operations are underway. Drilling is expected to be completed by the end of August 2025. If successful, the Jasper Well may be able to support a future Bitcoin mining project.\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 eleven 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 on 23 June 2025, the Company and M3 Helium have agreed to extend the date on which the Option should be exercised to 30 September 2025.\n \nFort Dodge, Kansas\n \nThe four water tanks which are to be positioned between Rost and the Brobee salt water disposal well (\"Brobee SWD\") have arrived on site and the catwalk between them has been installed. The remaining items of major equipment are the triplex pump for the Brobee SWD and the separator and knock-out (which together separate any liquids from the gas stream). These are anticipated to be delivered either during next week or by early September 2025.\n \nWith delivery times confirmed and the larger items already in place, M3 Helium continues to expect de-watering operations to commence in the first half of September 2025. The project overall remains under budget.\n \nOnce Rost is operational, M3 Helium will connect the pressure swing adsorption (\"PSA\") unit that is already on site which will purify the produced helium. The most efficient level of purity will be determined once production begins but, as a guide, M3 Helium is expecting to ship helium at around 75 per cent. purity. M3 Helium has secured delivery of a Bauer compressor, expected on site in mid...
