DISA Uranium's Groundbreaking Cleanup Initiative in Colorado

Last week, DISA Uranium Corporation marked a significant milestone by welcoming leaders from government, Tribal communities, and industry to its first-ever remediation project for Abandoned Uranium Mines (AUM) in Montrose County, Colorado. This project, located at the Mary Ann site, is not only a critical step for the company but also an important development in the broader context of uranium mine waste management and recovery efforts in the United States.

The event saw participants, including representatives from the Navajo Nation and the Colorado Division of Reclamation among others, come together to witness the capabilities of DISA's proprietary HPSA® technology. This advanced technology promises a new frontier in effectively addressing the environmental concerns stemming from legacy uranium mining.

On October 29, 2026, stakeholders visited the project site to gain insight into the innovative methods being deployed. The Mary Ann site stands out as the first project under DISA Uranium's NRC Service Provider License—the first and only license of its kind that permits installations of mobile HPSA technology directly at AUM locations.

The significance of the Mary Ann project goes beyond just cleanup; it represents a dual national priority—remediating hazardous waste while bolstering the nation's supply chain for nuclear fuel. Situated on Bureau of Land Management (BLM) property, this initiative helps establish a regulatory pathway to recover uranium in a manner coordinated with federal and state authorities.

According to Greyson Buckingham, CEO of DISA Uranium, this project is a monumental achievement. He emphasized the importance of transitioning past liabilities into resource recovery opportunities, noting that such endeavors aid in reducing American dependence on foreign uranium sources. The HPSA process involves a water-based mechanical operation designed to extract uranium-bearing fines from waste rock, ultimately returning cleaned coarse material to the site.

The site visit allowed attendees to observe the practical application of HPSA, engage in discussions about its deployment across multiple AUM locations, and understand its potential benefits. Stephen B. Etsitty, Executive Director of the Navajo Nation EPA, highlighted the agency's commitment to thoroughly evaluating resource recovery techniques to ensure effective and permanent cleanup of uranium waste—a notable concern for Tribal communities.

In his remarks, Etsitty drew attention to the collaborative nature of assessing HPSA technology, outlining their ongoing study funded by the EPA. This proactive approach signifies a shift towards responsible remediation that prioritizes the safeguarding of land and water resources from radioactive hazards.

The emphasis on community engagement and the voices of Tribal nations were echoed by Dr. Richard Luarkie from the Native American Mining and Energy Sovereignty Initiative. He pointed out that the legacy of uranium mining is not merely historical but is part of the daily reality for many Tribal communities. As new remediation strategies are explored, it is crucial for these communities to be integrally involved in shaping the future processes.

Beyond the Mary Ann project, DISA Uranium is busy expanding its remediation portfolio, with agreements covering over 375 legacy AUM sites, particularly in Colorado and Utah. These projects signify the first application of a replicable model for uranium recovery and remediation, ushering in a new era of responsible environmental management while also tapping into domestic uranium resources.

With its headquarters in Casper, Wyoming, DISA Uranium is dedicated to redefining uranium recovery. By turning abandoned waste sites into opportunities for resource recovery, the company aims to restore the past while securely powering the future—thus rebuilding a robust national uranium supply chain. As DISA Uranium progresses, the eyes of both the industry and communities affected by uranium mining remain focused on these promising developments.

This first cleanup project of its nature sets a precedent for future engagements and remediation efforts. As technology evolves and partnerships grow, there is a palpable movement toward a safer and more sustainable management of uranium mine legacies across the United States.
