Helix Exploration, the helium exploration and development company with near-term production assets within the ‘Montana Helium Fairway’, is pleased to announce the completion of drilling at the Inez #1 well in Rudyard Project, Montana.
Highlights:
· Total Depth (“TD”) of 6,510ft (1,985m) drilled in 19 days
· Significant helium gas-shows up to 948ppm (190x background) in drilling mud
· 4th production well completed and ready for testing
· Helium target at Rudyard continues to expand, with first well drilled into the southern part of the Rudyard dome
Bo Sears, CEO of Helix Exploration, commented:
“Helix Exploration continues to deliver with the completion of drilling at our fourth production well. This is our first extension well approximately two miles south of Linda #1 and within the grand Rudyard Field anticline-an expansive geologic structure confirmed by both seismic and shallow historical drilling. Inez #1 confirms the continuation of helium-bearing intervals across a broader portion of the structure, significantly enhancing our understanding of its scale and potential. Helix will now move directly on to wireline logging and flow testing of the Inez #1 well.”
Background
Helix completed drilling operations at Inez #1 well on 11 July 2025. The well is located approximately two miles south of the Linda #1 well which tested 1.2% helium with a flow rate of 3,800 Mcf/d.
Drilling at Inez #1 reached a Total Depth (“TD”) of 6,510ft (1,985m). The well terminated in Pre-Cambrian basement allowing the Company to assess the potential for additional pay in lower horizons. The Souris and Red River formations were intersected at 5,128ft and 5,267ft respectively, in line with prognosis, indicating that the well hit its target on the grander Rudyard anticline. Consistent helium gas shows were recorded with concentrations reaching up to 948ppm. These results mirror the helium-bearing zones encountered at Darwin #1 and Linda #1, which demonstrated free gas at 1.1% and 1.2% helium respectivley.
Strong helium shows in the southern dome support the Company’s view that the Rudyard Field represents a significant and expanding helium asset. Pending the results of a successful flow test, Inez #1 could allow the Company to expand its proven helium reserves into the southern dome, further de-risking the subsurface potential of Rudyard and increasing the proven commercial assets of the Company.
Helix will move directly onto wireline logging and flow testing helium grade and flow rates of the of the Inez #1 well with work-over rig and testing equipment ot be mobilised shortly.
