Clean TeQ Water Secures First Long-Term Polymer Supply and Licensing Deal for ATA® Technology at Rasp Mine, Broken Hill

ATA® Technology Meets Evolving Industry Tailings Management Standards

The mining industry is experiencing a significant shift in tailings management due to increased regulatory and investor scrutiny following global tailings dam failures and adoption of the Global Industry Standard on Tailings Management (GISTM). Wet tailings storage facilities now face stricter permitting, financing, and insurance challenges. Consequently, filtered tailings stacking—which deposits dewatered tailings as stable solids rather than wet slurry—has become the preferred method for modern mines aiming to improve safety and operational flexibility.

Clean TeQ Water’s ATA® technology addresses these challenges by efficiently producing stackable filter cake from full mine tailings streams. The proprietary process uses hydrocyclone classification to separate coarse and fine particles, applies tailored polymers to each fraction, and recombines them into a sand-like material that is easy to dewater. This method achieves higher cake solids and lower residual moisture compared to conventional flocculation-only techniques, reduces reagent use, minimizes water losses to tailings storage, and supports a smaller, more geotechnically stable tailings footprint.

Rasp Mine’s Advancement to Nameplate Capacity Enabled by ATA® Dewatering

The Rasp Mine, one of the world’s largest silver, lead, and zinc deposits located in Broken Hill, NSW, has historically been limited to 500,000 tonnes per annum processing capacity due to reliance on solar drying of tailings. The ATA® Tailings Dewatering Plant allows Broken Hill Mines to replace this labor-intensive, weather-dependent method and scale up to its 750,000 tonnes per annum nameplate capacity.

Extensive laboratory and pilot testing of ATA® technology on Rasp Mine tailings has validated its capability to meet moisture content targets, reducing deployment risk and ensuring reliable performance under the mine’s specific geochemical and operational conditions. This validation underpins the long-term supply relationship formalized in the Polymer Supply Agreement.

Details of the Polymer Supply and Technology Licence Agreement

The binding Polymer Supply Agreement designates Clean TeQ Water as the exclusive supplier of proprietary ATA® reagents for the Tailings Dewatering Plant and grants Broken Hill Operations a license to operate the ATA® technology at Rasp Mine. Revenue is performance-based, with both reagent supply and technology licence fees scaling according to the volume of dry tailings solids processed, aligning Clean TeQ Water’s earnings with mine throughput.

The agreement starts upon successful commissioning of the ATA® Tailings Dewatering Plant and extends for an initial five years, with options for up to three additional five-year renewals, potentially lasting 20 years. There is no minimum purchase commitment, so recurring revenue depends on sustained tailings processing volumes. Pricing and commercial terms remain confidential due to their sensitive nature. Clean TeQ Water notes that pricing reflects the unique tailings characteristics and commercial context of the Rasp project—the first commercial ATA® deployment—and is not indicative of future agreements.

Strategic Impact of CNQ’s First Recurring Revenue from ATA® Technology

The Polymer Supply Agreement marks a pivotal strategic achievement for Clean TeQ Water, transitioning the Rasp Mine project from a near-term engineering contract into a long-term, predictable revenue source. Previously, revenue was solely from the Design and Construct contract announced on 15 May 2026. The addition of up to 20 years of reagent supply and licensing income transforms the ATA® platform’s revenue profile, showcasing its recurring revenue potential as mining shifts toward safer filtered tailings disposal.

This deal serves as a commercial validation of the ATA® technology model, confirming mine operators’ willingness to commit to multi-year supply and licensing contracts. As Clean TeQ Water’s first long-term revenue stream from ATA®, the Rasp Mine agreement establishes a benchmark and reference for future deployments, potentially enabling similar arrangements across the mining industry.

Agreement Conditions and Binding Terms

While the Polymer Supply Agreement is binding, reagent supply and technology licence payments commence only after successful commissioning of the ATA® Tailings Dewatering Plant under the Design and Construct contract announced on 15 May 2026. This staged structure ensures revenue recognition aligns with operational readiness.

The agreement allows Broken Hill Operations to terminate for convenience with notice. In such cases, BHO must pay a lump sum licence fee to retain the ongoing right to use ATA® technology at Rasp Mine, protecting Clean TeQ Water’s intellectual property and providing financial compensation for early termination. No other material terms or unusual termination provisions exist, consistent with ASX Guidance Note 8.

Complementing Near-Term Construction Revenue

The Polymer Supply Agreement complements Clean TeQ Water’s near-term construction revenue from the Design and Construct contract for the ATA® Tailings Dewatering Plant announced on 15 May 2026. This two-phase revenue approach captures immediate engineering and construction value while establishing a long-term recurring revenue stream once operational.

Securing both contracts with Broken Hill Mines strengthens Clean TeQ Water’s customer relationship, creating multiple revenue touchpoints throughout the technology deployment lifecycle. This integration increases customer retention and dependency on ATA® polymer supply and technical support over a potential 20-year horizon.

CEO Peter Voigt Highlights Strategic and Operational Importance

Peter Voigt, CEO of Clean TeQ Water, emphasized that the Polymer Supply Agreement is a significant milestone, converting the Rasp Mine ATA® deployment into a long-term recurring revenue stream potentially spanning 20 years. He noted the agreement complements near-term construction revenue and demonstrates ATA® technology’s recurring revenue potential amid the mining industry’s transition to safer filtered tailings disposal. Voigt expressed satisfaction in continuing collaboration with Broken Hill Mines through commissioning and extended operation.

Industry Drivers Fueling ATA® Technology Adoption

The global mining sector faces increasing pressure to upgrade tailings management due to regulatory reforms, investor demands, and reputational risks following high-profile tailings storage failures. The Global Industry Standard on Tailings Management (GISTM) sets new safety, environmental, and transparency benchmarks. Concurrently, financiers and insurers are reluctant to support wet tailings storage, creating a market gap that filtered tailings solutions like ATA® address.

These industry trends create a favorable environment for Clean TeQ Water’s ATA® technology. Mines aiming to increase throughput, reduce environmental risk, improve permitting, secure financing, and enhance flexibility are motivated to adopt advanced dewatering. The Rasp Mine’s shift from solar drying to mechanical dewatering and capacity increase from 500,000 to 750,000 tonnes per annum exemplifies this trend. As regulations tighten and scrutiny grows, the market for filtered tailings technology is expected to expand, offering multiple deployment opportunities across jurisdictions and commodities.

Pricing Model and Commercial Considerations

Clean TeQ Water has not disclosed specific pricing under the Polymer Supply Agreement due to commercial sensitivity. The pricing model links reagent supply and technology licence fees to tailings volume processed, with potential upside from plant expansion. This volume-based structure aligns incentives as Clean TeQ Water’s revenue grows with increased throughput.

The company clarified that pricing for the Rasp Mine reflects its unique tailings characteristics and commercial context as the first commercial ATA® deployment and is not a pricing template for future projects. Future agreements may vary based on tailings chemistry, plant scale, competition, and customer needs. Clean TeQ Water positions the Rasp contract as a commercial reference point, allowing flexibility to optimize value capture in subsequent deployments.
