Nick Tulloch, Chief Executive Officer of Mendell Helium, said: “We are pleased to publish our annual report for the year ended 31 March 2026, a year which provided the platform for the next phase of our development of a helium production operation in Kansas.

“Rost 1-26 and Rost 2-26 will be the hub of these plans. With recorded helium concentrations of 5.1% and 11.5% respectively, we have the potential for very significant production. We know from our experience with Rost 1-26 that increasing gas flows follow sustained removal of water and Rost 2-26 is following the same pattern, albeit with a far higher helium composition. As production develops, we will continue to work on our surface operations to enable purification of greater gas volumes. As previously announced, there may be merit in fracking Rost 2-26. This operation – if we proceed – is within our budget and could be completed in a matter of weeks.

“Our joint venture with Ritchie Exploration Inc. could not have got off to a better start with strong production from Schneweis Ventures 13A with gas and water flowing from reservoir pressure.  To say this is a positive sign would be an understatement. This is a well that has considerable promise and, with access to a pipeline, production is not constrained by surface purification.

“We are finalising plans for new wells in Fort Dodge and we expect to update investors over the coming weeks on our progress.”

Overview of Mendell Helium

Mendell Helium is a helium producer in Kansas, USA where it operates through its wholly owned subsidiary M3 Helium.

M3 Helium’s flagship well, Rost 1-26, is in Fort Dodge, just to the east of Dodge City, Kansas. It has been tested as containing 5.1% helium composition and a drill stem test yielded a maximum flow rate of approximately 2,900 Mcf per day. Water removed from Rost 1-26 is delivered to Brobee, a nearby disposal well that has been permitted at 10,000 barrels of water per day at 1,200 psi.  Production at Rost 1-26 commenced in early November 2025 and the most recently recorded flow rate in December 2025 was 250 Mcf per day equating to approximately $1.4 million of helium per year (at $300/Mcf helium).

M3 Helium has subsequently drilled a second well, Rost 2-26, which is currently being de-watered and early results have been encouraging. In particular Rost 2-26 has reported a helium composition of 11.5%.  It also owns additional leases in the Fort Dodge area capable of supporting up to eight new production wells. M3 Helium has also agreed a joint venture with Ritchie Exploration, Inc. to recomplete the Schneweis Ventures 13A, a well with a drill stem test of over 10,000 Mcf per day and a historic flow rate of 300 Mcf per day. Since coming back on line, the well has recorded peak flow rates of up to 700 Mcf per day, although rates have been variable during de-watering.

At the Rost wells in Fort Dodge, M3 Helium treats the raw gas on site to concentrate the helium and has leased two tube trailers which it uses for deliveries to its offtaker.

M3 Helium also has interests in five producing wells (Peyton, Smith, Nilson, Bearman and Dimmitt) within the Hugoton gas field in South-Western Kansas, one of the largest natural gas fields in North America. Significantly these wells are in the proximity of a gathering network and the Jayhawk gas processing plant meaning that producing wells are all tied into the infrastructure.
