Mendell Helium plc has reported steady operational progress across its US helium assets, alongside continued preparations for its planned listing on London’s junior market.
Drilling at the Rost Twin well is advancing efficiently, reaching a depth of 4,540 feet within the first week, with a total target depth of 5,600 feet. In addition to targeting the primary Morrow sands, the well is expected to evaluate additional helium-bearing zones, potentially enhancing the broader resource outlook.
Elsewhere, the company is progressing design upgrades for the Brobee salt water disposal well—an important component of field infrastructure—and is preparing for the re-completion of the Schneweis Ventures 13A well, which could further support near-term production capacity.
On the corporate front, Mendell Helium’s proposed admission to the Alternative Investment Market is now anticipated to move forward in April 2026. The admission document is expected to be published during the month, with trading targeted to commence in late April. Concurrently, the company intends to exercise its option to acquire M3 Helium upon admission, consolidating its position within the US helium sector.
Highlights

· In addition to Morrow sands, the Rost Twin will test other helium prospects
· Design process for upgrade of Brobee salt water disposal well underway

· AIM admission document now expected to be published in April 2026
Nick Tulloch, Chief Executive Officer of Mendell Helium and Chairman of M3 Helium, said: “The developments across M3 Helium’s business are gaining pace and, in particular, the speed at which the Rost Twin is being drilled adds considerable confidence to the proposed Fort Dodge field development plan.
“Needless to say, we acknowledge that our move to AIM has taken longer than originally hoped but, conversely, the growth in M3 Helium’s Kansas operations has not only exceeded our expectations but also remains the priority, particularly in light of the ongoing and potentially severe disruptions in global helium market. It is still too early to predict exactly how helium pricing will change as a result of the conflict in the Middle East but what is apparent is that it has exposed some fragility in both international and national helium supply chains. There will be an advantage to helium producers over the coming months in partnering with leading gas processors and we are determined to position M3 Helium prominently in the market.
“I can assure all of our investors that admission to trading on AIM is a very near term target for Mendell Helium and, alongside that, we are working to ensure that the Company continues to punch above its weight as we deal with much larger counterparties in the helium market.”
