Rudyard Operational Update

Further to the Company's announcement on 3 September 2026, Helix Exploration PLC (AIM: HEX, OTCQB: HEXFF), the US-focused helium producer and liquefier, provides the following update on commercial operations at the Rudyard facility in Montana following the hearing held on 15 October 2026 before the Montana Board of Oil and Gas Conservation ("MBOGC").

The MBOGC has granted an exemption, subject to standard periodic gas composition review, allowing the Company to vent waste gas (which at Rudyard is primarily nitrogen) and therefore restart Rudyard operations with immediate effect.

The Company has commenced the process of restarting the wells and production facility and expects to recommence filling tube trailers on a continuous rotation basis, pursuant to the helium sales arrangement announced on 25 September 2026, within the coming days. Both of the Company's leased tube trailers are at the facility awaiting filling. A further announcement will be made once flow rates have been established and filling has recommenced.

Bo Sears, Chief Executive Officer, commented:

"We thank the Montana Board of Oil and Gas Conservation for granting its approval to restart operations at Rudyard. We look forward to bringing the wells back on and restarting the facility while simultaneously advancing our field expansion programme."
