Notes to Editors

Helix is a Montana-focused helium producer, listed on the London Stock Exchange. Its flagship Rudyard Project has rapidly evolved into Montana's first producing helium field.

Rudyard hosts three stacked helium-bearing reservoirs within a proven geological setting, with an initial four wells delivering commercial helium flow rates.

Production commenced in February 2026 through an on-site PSA processing facility, supported by established infrastructure and a helium sales agreement with a major industrial gases group.

The project benefits from shallow reservoir depths, low development costs, negligible hydrocarbons or CO₂, and significant expansion potential.

In July 2026, Helix completed the acquisition of the Keyes Helium Complex in Oklahoma which resulted in Helix becoming an independent helium producer that also controls liquefaction, enabling the Company to capture the full margin from wellhead to liquid delivery.
