Helix Exploration PLC (AIM: HEX) has begun construction at its flagship Rudyard Project in northern Montana, marking a major milestone in its push to become the state’s first helium producer.
Civil works began in early July, with ground clearance and soil compaction now underway ahead of the installation of a reinforced concrete pad. Delivery of key infrastructure, including a PSA (Pressure Swing Adsorption) plant and membrane modules from Texas, is scheduled for August 2025, with the compressor units to follow shortly after.
Highlights:
· Civil construction underway at the Rudyard Plant site, including ground clearance and compaction prior to installation of a reinforced concrete pad.
· PSA plant and membrane modules from Texas to Montana on track for delivery in August 2025.
· Compressor units expected to follow soon after.
· First helium production targeted to commence once final equipment delivery & integration is completed onsite.
“We are now fully underway with construction at the Rudyard Plant site, another important step toward being the first helium producer in the State of Montana,” said CEO Bo Sears.
With four production wells already drilled and a fifth currently underway, Helix says it remains on track to deliver one of North America’s fastest and most cost-efficient helium developments. The company only listed on the London markets a little over a year ago and is now closing in on its first helium output.
Before production can begin, the company must complete compressor installation, final plant hookups, and pass regulatory inspections.
Helix shares have surged more than 100% in the past two months, reflecting investor optimism ahead of the upcoming production milestone.
