Casper, Wyoming Disa Technologies, Inc. (Disa), an innovative materials liberation company, today announced the closing of a US $15 million Series A. The Series A round was led by Evok Innovations, the Wyoming Venture Capital (WYVC) Fund from the Wyoming Business Council (WBC), and McKinley Alaska Private Investment, alongside participation from previous and new investors, including Halliburton Labs, The UCeed Energy Fund, and the University of Wyoming Foundation.


The Series A funds will scale up Disa’s High-Pressure Slurry Ablation (HPSA) technology for commercial installations in minerals processing circuits and remediation and recycling operations at legacy mine sites.


"We successfully demonstrated that HPSA technology can significantly remediate legacy uranium mine sites and executed successful pilots with leading global mining companies on various critical minerals. These funds will allow Disa to take its HPSA technology to the next level of scalability and commercialization,” says Greyson Buckingham, CEO and Co-Founder of Disa. “Our mission is to deliver innovative remediation and minerals processing solutions that disrupt industry best practices, enhance global resource utilization, and benefit the environment and the communities we serve.”


“Our industry-leading investors and dedicated team of problem solvers put Disa in a strong position to capitalize on playing a major role in advancing sustainable solutions for critical minerals recovery and mine waste recycling,” says John Lee, COO and Co-Founder. “Wyoming is a leader for innovation in the energy and minerals industries, and we are proud to continue that legacy with our HPSA technology.”


Disa recently participated in a treatability study on the Navajo Nation sponsored by the U.S. EPA and Navajo Nation EPA, which validated Disa as a viable treatment technology for legacy uranium mine waste remediation.


Disa’s successes include completing a commercial project with Newmont Corporation, recently installing a continuous commercial unit at a phosphate mill, working with Fluor Corporation to scale its processing capabilities to 50+ tons per hour, and delivering Disa pilot units to several global mining companies and leading minerals processing laboratory facilities.


“Disa’s innovative technology will play a vital role in the energy transition by allowing operators to recover critical minerals more sustainably and economically,” says Marty Reed, Partner, Evok Innovations. “We believe Disa is positioned for massive growth, and we look forward to supporting Disa as it revolutionizes the minerals processing and remediation industries.”


“McKinley Alaska is pleased to be part of Disa’s scale-up. Advancements in mining technology, energy efficiency, and environmental impact mitigation are very relevant to Alaska. We are excited to see Disa’s innovative technology play an important role in developing the critical mineral industry in Alaska and across the United States,” says Rob Gillam, President of McKinley Alaska Private Investment, LLC. 


“We recognize the innovation Disa brings to the state of Wyoming and the minerals industry worldwide, and we are excited about how this investment will allow them to scale and broaden their impact,” says Gordon Finnegan, Equity Portfolio Manager, WYVC. “Our partnership with Disa began with an early-stage Kickstart grant, and we are pleased to be able to support them once again as they take their company and technologies to the next level.”


"Halliburton Labs is excited to help accelerate the scaling of Disa’s innovative minerals processing solutions with our industrial commercialization experience and global business network," says Dale Winger, Managing Director, Halliburton Labs.
