Nick Tulloch, CEO, commented:

"Mendell Helium is focused on growing helium production from M3 Helium Corporation's ("M3 Helium") operations in Kansas-an increasingly vital resource for industries ranging from healthcare to high tech. With M3 Helium's Rost well expected to commence dewatering in July 2025, we are at a pivotal moment in its development.  Alongside that, we are coupling these plans with the development of a Bitcoin treasury management policy and a planned move to AIM.  As our newsflow develops over the coming months, we want our shareholders to be closely connected to our journey.

"The launch of our new website marks a step forward in how we communicate. It gives our investors a dedicated space to track our progress, understand our strategy, and engage with the company more directly. We're committed to transparency and see this as an essential tool for building long-term trust and alignment with our stakeholders."

Overview of M3 Helium

Mendell Helium announced on 27 June 2024 that it has entered into an option agreement to acquire the entire issued share capital of M3 Helium through the issue of 57,611,552 new ordinary shares in Mendell Helium to M3 Helium's shareholders.  The exercise of the option will constitute a reverse takeover pursuant to AQSE Rule 3.6 of the Access Rule Book and is subject to, inter alia, publication of an admission document.

M3 Helium has interests in ten wells in South-Western Kansas of which five (Peyton, Smith, Nilson, Bearman and Demmit) are in production.  Eight of the company's wells are within the Hugoton gas field, 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 can quickly be tied into the infrastructure.

The ninth well, Rost, is in Fort Dodge, just to the east of Dodge City, Kansas.  It was tested in July 2024 as containing 5.1% helium composition and a previous drill stem test yielded a maximum flow rate of approximately 2,900 Mcf per day. M3 Helium owns a mobile Pressure Swing Adsorption production plant which has been installed on site and will be used to purify the produced helium.  The plant is capable of processing up to 800 Mcf per day of raw gas and purifying it up to 99.999% helium.

The tenth well, Brobee, is a disposal well that has been tested at over 4,500 barrels of water per day at 640 psi.
