Project Update at the Flagship Rudyard Project

Helix Exploration, the helium exploration and development company with near-term production assets within the 'Montana Helium Fairway', is pleased to provide an update on its flagship Rudyard Project as it progresses towards first helium gas production.

Highlights:

·      The PSA compressor, the final long lead item required for helium production, has been fully assembled and is en route to Rudyard.   It is estimated that the compressor will be onsite at Rudyard in the next 3 days.  All preparatory work has now been completed offsite to reduce installation time and commissioning is expected to take 4-5 business days once onsite.

·      Offtake - discussions with industry leaders are expected to be concluded once first gas commences and further announcements will be made in due course.

·      Hydrogen potential - Helix is in active discussions with several globally recognised Tier 1 partners regarding potential hydrogen-related collaboration. These discussions remain at an early stage, and the Company will update the market on any further developments.

·      Helix has acquired additional leases at Rudyard totaling 1,363 acres for modest cash consideration

·      Inez#1 - Drilling operations have been running slower than usual due to severe winter weather.  We are currently pausing operations until after the holiday season when the drilling campaign is expected to resume.

Bo Sears, CEO of Helix Exploration, commented: "We are excited to soon become the first helium producer in the State of Montana & the opportunities that production will present for the Company.  The team remain laser focused on maintaining the momentum built up since the IPO and I look forward to updating the market on the anticipated production milestone."
