Quantum Helium Ltd (AIM:QHE) has described December as "exceptionally productive", as the small-cap firm recapped what has been a year of transformation.
The company, which rebranded and rebooted in 2025, on Tuesday released a year-end operational update covering recent activity across its portfolio.
It confirmed completion of the Sagebrush 3D seismic survey and finalisation of an independent resource report at Coyote Wash.
The company added that the Sproule ERCE report verified Coyote Wash as its second certified helium resource, which takes total independently assessed 2U gross helium across Sagebrush and Coyote Wash to more than 1 billion cubic feet. And, it also confirmed that all funds from a letter of credit for the extended Sagebrush-1 flow test have been transferred.
"This month has been exceptionally productive for Quantum, with a number of major milestones all achieved within days of each other," said chief executive Howard McLaughlin.
"Finishing the Sagebrush 3D seismic, finalising the Sproule ERCE report on Coyote Wash, and completing the Irrevocable Letter of Credit collectively move us a significant step closer to flow testing Sagebrush-1 and progressing the wider development plan."
McLaughlin added: "We enter 2026 with strong momentum, a clear operational pathway, and a portfolio that continues to strengthen. I wish all our investors and stakeholders a safe and enjoyable Christmas and holiday season."
