Clean TeQ Water Signs Long-Term ATA® Polymer Supply and Technology Licence Agreement for the Rasp Mine in Broken Hill
17 July 2026
Clean TeQ Water is pleased to announce it has entered into a long-term Polymer Supply Agreement with Broken Hill Operations, a wholly owned subsidiary of Broken Hill Mines, for the supply of proprietary ATA® reagents and the licensing of ATA® technology at the Rasp Mine in Broken Hill, New South Wales, Australia.
The agreement follows the Design and Construct contract for the ATA® Tailings Dewatering Plant announced on 15 May 2026.
How the ATA® Process Works
Under the Polymer Supply Agreement, Clean TeQ Water is appointed as the supplier of the proprietary ATA® reagents used by the ATA® Tailings Dewatering Plant, and BHO is granted an ongoing licence to operate Clean TeQ Water’s proprietary ATA® technology at the Rasp Mine. Both the reagent supply revenue and technology licence fee scale with the volume of dry tailings solids processed through the plant.
The Polymer Supply Agreement has an initial term of five years commencing on completion of commissioning of the ATA® Tailings Dewatering Plant and may be renewed by BHO for up to three further five-year periods, to a maximum term of 20 years. The agreement represents the first long-term recurring revenue stream generated by ATA®, marking an important milestone in the commercialisation of the technology.
The Rasp Mine, long-established as one of the largest silver, lead and zinc deposits in the world, operating in Broken Hill, New South Wales, is currently ramping up to its 750,000 tonnes per annum nameplate processing capacity. The ATA® Tailings Dewatering Plant allows Broken Hill Mines to transition away from the historical practice of ‘solar drying’ of tailings on site, which has to-date limited processing throughput to 500,000 tonnes per annum.
The ATA® Tailings Dewatering Plant is a conventional mine tailings dewatering system enhanced by Clean TeQ Water’s proprietary ATA® rapid dewatering technology. The technology has been extensively tested (through laboratory and piloting phases) specifically on the Rasp Mine tailings, producing high-quality filtered tailings and meeting the Mine’s required tailings moisture content target.
ATA® - Supporting the Shift Toward Filtered Tailings
ATA® is Clean TeQ Water’s proprietary tailings dewatering technology, using a dual polymer system to enable efficient production of stackable filter cake from full mine tailings streams. The technology is designed to deliver high cake solids and low residual moisture while reducing reagent consumption and water losses compared with conventional flocculation-only approaches.
By delivering the cake solids and stack stability traditionally associated with high-cost pressure filtration at materially lower capital and operating cost, ATA® expands the range of mining operations for which filtered tailings becomes economically and technically viable.
“It complements the near-term construction revenue from the Design and Construct contract with ongoing reagent supply and technology licensing revenue, and demonstrates the recurring-revenue potential of the ATA® technology as the mining industry transitions towards safer, filtered tailings disposal.
“We are delighted to be working with Broken Hill Mines on the Rasp project and look forward to supporting them through commissioning and many years of operation.”
