Innovative Partnership Aims to Remediate Legacy Uranium Waste in Colorado

Frontier Nuclear and DISA Technologies have joined forces to remediate historical uranium mine waste at the Maybell project in Colorado, recovering valuable uranium and critical minerals.

Innovative Partnership Aims to Remediate Legacy Uranium Waste in Colorado

In a groundbreaking collaboration, Frontier Nuclear and Minerals (NASDAQ: FNUC) has teamed up with DISA Technologies to extract uranium and critical minerals from historical waste dumps at the Maybell uranium project in Moffat County, Colorado. This partnership not only aims to address environmental impacts but also to unlock the economic potential of legacy mining sites.

The Maybell site, spanning 9,497 acres includes 480 federal mining claims and 1 state exploration lease. Historical operations have already yielded 5.3 million pounds of U3O8 and ground surveys have identified 17 prospective waste dumps on the property. DISA will deploy its innovative High-Pressure Slurry Ablation (HPSA) system, a chemical-free process that uses high-velocity slurry collisions to separate target minerals from waste material.

Innovative Technology for Environmental Remediation

An independent treatability study conducted by the U.S. Environmental Protection Agency (EPA) has shown that the HPSA technology can reduce uranium concentrations in treated material by 61 to 94 percent with comparable reductions in radium-226. The process concentrates over 90 percent of the uranium into just 17 percent of the total processed mass, leaving the remaining bulk material clean enough to stay on site. This significantly reduces the volume of material requiring regulated disposal.

High-Pressure Slurry Ablation (HPSA) is a modular, chemical-free process that selectively separates uranium and other target minerals from waste material using high-velocity slurry collisions. This technology not only enhances the efficiency of mineral recovery but also minimizes environmental impact.

Strategic Partnership and Regulatory Support

Under the terms of the agreement, DISA will fully fund and operate the remediation program, while Frontier will retain a sliding-scale net revenue royalty of 2.5 to 4 percent. This arrangement ensures that Frontier incurs zero capital or operating expenditures, making the project financially viable and environmentally sustainable.

DISA will launch a six-month characterization program using assay and gamma probes to quantify recoverable minerals before applying for necessary operational permits. In DISA became the first company to receive a Service Providers License from the U.S. Nuclear Regulatory Commission (NRC) providing a clear regulatory pathway for legacy waste remediation.

The federal government is actively supporting these initiatives under Secretarial Order No. 3436 which mandates federal agencies to prioritize domestic mineral recovery from existing mine waste. Recent directives from the U.S. Administration aim to quadruple domestic nuclear capacity by 2050 a target projected to push national uranium demand from 47 million pounds to approximately 190 million pounds annually.

Expanding Exploration and Future Prospects

Parallel to the Colorado agreement, Frontier is expanding its international exploration portfolio. The company is currently finalizing a maiden mineral resource estimate for its Engo Valley uranium project in Namibia a premier global mining jurisdiction, with completion targeted for the middle of the third quarter of 2026.

Frank Wheatley CEO of Frontier Nuclear, expressed enthusiasm about the partnership: “We are pleased to have partnered with DISA to apply its breakthrough process to remediate abandoned uranium mine waste at our Maybell Project, and to recover valuable uranium and critical minerals, while addressing the environmental impacts of historical uranium mining.”

“With uranium demand at multi-decade highs and the U.S. Government actively prioritizing domestic critical mineral recovery, the timing could not be better to unlock the value contained in our Maybell project’s legacy waste dumps,” Wheatley added.
