Sproule ERCE Confirms Major Helium Resource at Coyote Wash
 
Over 1 BCF of Independently Verified Gross Helium Resources Across Colorado Projects

 

Establishes Quantum Helium Among the Largest Independently Certified Helium
Companies on the LSE by resource size

Quantum Helium Limited (AIM: QHE), advancing helium, hydrogen and hydrocarbon
projects in the USA, is pleased to announce receipt of the independent
resource report from Sproule ERCE for the Coyote Wash Project in Colorado,
where Quantum holds a 100% working interest.

The report estimates 2U (Best Estimate) gross recoverable helium of 0.97 BCF
at Coyote Wash, which, when combined with the Sproule ERCE-verified 2U gross
helium resource of 0.134 BCF at Sagebrush, establishes 1.104 BCF of
independently verified 2U gross helium across the Company's Colorado
portfolio.

This represents Quantum's second independently evaluated helium resource,
reinforcing the continued growth and maturing technical confidence in the
Company's strategy.

Sproule ERCE has also completed its assessment of the oil potential at Coyote
Wash, confirming 1U / 2U / 3U recoverable oil estimates of 150 / 420 / 750
thousand barrels across a single mapped Ismay prospect.

Highlights

·      Sproule ERCE estimates 2U gross recoverable helium of 0.97 BCF at
Coyote Wash

·      Combined with Sagebrush, Quantum now has 1.104 BCF gross (828
MMscf Net) 2U helium, all independently evaluated.

·      Potential gross value of ~ US$331 million ($300/Mscf)

·      Establishes Quantum as having one of the largest independently
verified helium portfolios among London-listed helium companies

·      Sproule ERCE also identifies up to 750,000 barrels of potentially
recoverable oil at an Ismay prospect with three potential well locations.

·      3D seismic acquisition at Sagebrush complete, with results of
processing and interpretation expected in the new year to provide additional
drillable oil and helium prospects

·      Positive engagement with the Bureau of Indian Affairs (BIA) as
the Company progresses towards approval for the extended flow test at
Sagebrush-1

Quantum Chief Executive, Howard McLaughlin, commented: "This is a defining
moment for Quantum. With Sproule ERCE now independently evaluating more than
one billion cubic feet of 2U gross helium across Sagebrush and Coyote Wash, we
have established ourselves among the larger independently certified helium
companies on the London market. Few companies can point to two independently
evaluated helium projects, a drilled and cased discovery well ready for
testing, and a completed seismic acquisition programme that could further
expand our resource base."

"The Sproule ERCE outcome gives us tremendous confidence in the scale and
quality of our portfolio. It validates our disciplined technical work,
strengthens our strategic position, and sets the foundation for a highly
active 2026. Our engagement with the BIA has been very constructive, including
a meeting with senior officials this week, and we continue to progress towards
approval for the extended flow test at Sagebrush-1. With meaningful project
milestones ahead, shareholders can look forward to a sustained period of
value-building newsflow."
