Sproule: Coyote Wash is a major Helium Resource
Quantum Helium Limited has announced a significant helium resource confirmation at its Coyote Wash Project in Colorado, with Sproule ERCE estimating 0.97 BCF of 2U gross recoverable helium. This, combined with the 0.134 BCF at Sagebrush, brings the company's total independently verified 2U gross helium resource to 1.104 BCF across its Colorado portfolio, positioning Quantum Helium as one of the largest independently certified helium companies on the LSE by resource size. Additionally, Sproule ERCE identified potential oil resources of 150 to 750 thousand barrels across a single Ismay prospect. Disclaimer*
