Quantum Helium Limited (QHE) has commenced field operations for the high-resolution 3D seismic programme at its Sagebrush helium project in Colorado, USA.
Seismic crews and equipment have now arrived on site, with acquisition operations commencing this week.
The survey will cover approximately 16 square miles across the Sagebrush field and adjoining leads, linking to existing 3D coverage at the company’s other major project, Coyote Wash.
The programme is designed to image subsurface structures in the Leadville Formation and Ismay algal mounds, and should establish size, shape and continuity of the known helium accumulation intersected in Sagebrush-1.
Processing and interpretation of the results is likely to be completed in the first quarter of 2026, refining future drilling targets and supporting development planning.
Meanwhile, preparations for the extended well test at Sagebrush-1 remain ongoing, with final approval from the Bureau of Indian Affairs required before operations can commence. The BIA's review process was temporarily delayed by the recent U.S. government shutdown, but engagement with regional offices has resumed.
"We're delighted to have seismic crews now mobilised and field work underway at Sagebrush,” said Howard McLaughlin, chief executive of Quantum Helium.
“This 3D programme will give us, for the first time, a detailed image of the subsurface geometry around the Sagebrush-1 helium discovery. The survey will help define the extent of the Leadville structure, identify additional algal mound leads nearby, and link seamlessly with our Coyote Wash data to the north. Once processed, this dataset will underpin our next round of drilling and potential production planning in 2026."

Good to see the newly-named Quantum Helium powering ahead on its US assets. The acquisition of 3D seismic is an important step on the way towards further drilling and resource definition, and will provide a useful jumping off point for Quantum’s 2026 programme of works. Next year could be transformational for the company.
