Winnipeg, Manitoba--(Newsfile Corp. - July 7, 2026) - Frontier Nuclear and Minerals Inc. (NASDAQ: FNUC) ("Frontier"), a nuclear fuel cycle company, announces that it has signed an agreement with DISA Technologies Inc. ("DISA") to characterize and remediate legacy uranium mine waste dumps and to recover saleable uranium at Frontier's 100% owned Maybell uranium project (the "Maybell Project") in Colorado.
Environmental remediation and uranium recovery will occur simultaneously
at the former Maybell uranium mine
Highlights:
DISA will deploy its patented High-Pressure Slurry Ablation ("HPSA™") system in modular mobile plants to recover saleable uranium and other critical mineral concentrates from waste dumps at the Maybell Project
Frontier Nuclear will be paid a net revenue royalty based on a sliding scale royalty rate of between 2.5% to 4% based on uranium price and derived from the sale of uranium and other critical minerals extracted from the waste dumps at the Maybell Project
DISA will operate the waste remediation program at the Maybell Project and pay all associated costs
No capital or operating costs will be payable by Frontier
A total of 17 separate prospective waste dumps have been identified through ground surveys at the Maybell Project to date, and others may be added over time
HPSA™ is a patented, chemical-free, modular process that selectively separates uranium and other target minerals from waste material using high-velocity slurry collisions.1
CEO Remarks
"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," said Frank Wheatley, CEO of Frontier.
"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."
Next Steps:
DISA will:
Launch a characterisation programme with a combination of assay and gamma probe to determine likely quantities of uranium and other recoverable minerals present in the waste dumps, expected to take approximately six months
Apply for all requisite permits necessary to commence treatment of waste and recovery of payable concentrates using HPSA™ technology
Pay Frontier a net revenue royalty on future sales of metals concentrates
Advantages of HPSA™:
The HPSA™ process treats surface dumps of previously partially mined and aggregated material, and has been independently validated through a U.S. Environmental Protection Agency ("EPA") treatability study ("EPA Study") conducted at three Navajo abandoned uranium mine sites in 2022 and published in December 2023
