Operational update

Helix Exploration PLC, the helium exploration and development company with near-term production assets within the 'Montana Helium Fairway', provides an operational update on its flagship Rudyard project.

During the final stages of commissioning, the Company identified a minor technical issue with the Variable Speed Drive ("VSD"), which had temporarily delayed the start of helium production. The issue has since been resolved, and the VSD is now operating seamlessly.

Helix intends to provide a further update to the market regarding its production milestone together with a broader operational update, during the week commencing 16 February 2026. Once production is underway, Helix plans to host several prospective offtake partners at the Rudyard site. The Company will evaluate potential offtake arrangements with a focus on securing the most attractive terms to maximise shareholder value.

Bo Sears, Chief Executive Officer of Helix Exploration, commented:

"Our team has worked tirelessly, and thanks to their dedication and expertise, we are now closer than ever to achieving a significant milestone - becoming the first helium producer in the state of the Montana.

"The Board remains confident in the tremendous potential of the Rudyard project and is excited to take this important step towards production, creating value for our shareholders while contributing to the global helium market."
