Clean TeQ Water Limited (ASX:CNQ) shares moved 1.12% higher to AUD 0.45 during the morning session on 15 May 2026 after the company announced it had secured a new Mining sector contract tied to its proprietary ATA tailings dewatering technology. The stock has also climbed 136.84% over the past year, with the latest market reaction appearing to reflect investor attention on the company’s expanding project pipeline and Recurring Revenue opportunities linked to the agreement.

The latest update centred on a Design and Construct contract awarded by Broken Hill Operations Pty Ltd, a Wholly Owned Subsidiary of Broken Hill Mines Limited (ASX:BHM), for the development of an ATA Tailings Dewatering Plant at the Rasp Mine in Broken Hill, New South Wales.

The agreement marks another step in Clean TeQ Water’s strategy of commercialising its tailings management technologies across the mining sector, particularly as mining operators continue transitioning away from traditional wet tailings storage systems toward filtered tailings disposal solutions.

New Contract Expands ATA Technology Deployment

Under the agreement, Clean TeQ Water will undertake the engineering, procurement, Manufacturing, supply and installation of the new dewatering facility at the Rasp Mine.

The plant will operate as a single-train facility designed for 750,000 tonnes per annum dry solids throughput. According to the company, the system is intended to produce a filter cake suitable for in-pit filtered tailings stacking while avoiding the additional Capital and operating costs typically associated with pressure filtration systems.

Construction works are expected to begin immediately following execution of the contract, with practical completion targeted during the first half of calendar year 2027, corresponding with 3Q FY27.

The contract forms part of Broken Hill Mines’ broader operational ramp-up strategy at the Rasp Mine, where the company is targeting a 750,000 tonnes per annum nameplate production rate.

The mine, which is recognised as one of the world’s major silver, lead and zinc deposits, has historically relied on solar drying methods for tailings management. According to Clean TeQ Water, those methods had contributed to throughput limitations of approximately 500,000 tonnes annually.

The new ATA Tailings Dewatering Plant is expected to support higher production capacity while also enabling a transition away from historical wet tailings management practices.

Investor Attention Turns to Potential Long-Term Revenue Streams

Alongside the Design and Construct contract, Clean TeQ Water disclosed that it is finalising negotiations on a Polymer Supply Agreement with Broken Hill Operations.

If executed, the arrangement would involve Clean TeQ Water supplying proprietary ATA reagents while also licensing the ATA technology for ongoing use at the Rasp Mine.

The proposed agreement has attracted market interest because it introduces the possibility of recurring revenue in addition to near-term construction-related income from the current contract.

Management noted that the arrangements announced are expected to be materially positive relative to the company’s current revenue base and financial projections.

Payments linked to the construction agreement are expected to be received progressively throughout delivery of the project works.

The company also stated that the Polymer Supply Agreement is intended to be executed within 14 days of the Design and Construct agreement. If the supply agreement is not completed within that period, either party retains the right to terminate the Design and Construct contract within a specified timeframe.

Despite this provision, Clean TeQ Water confirmed the contract is not subject to any additional internal approval requirements from Broken Hill Mines.

ATA Technology Positioned Around Tailings Industry Shift

The latest contract announcement also highlights the growing industry focus on alternative tailings management solutions.

Clean TeQ Water’s ATA technology is designed to improve tailings dewatering efficiency through a dual polymer system that enables the production of stackable filter cake from full mine tailings streams.

The process involves hydrocyclone classification of coarse and fine particle fractions, application of different polymers to each stream, and recombination into a single material intended to improve dewatering outcomes.

According to the company, the technology aims to deliver reduced residual moisture, lower reagent consumption and reduced water losses compared with more conventional approaches.

The company also emphasised that filtered tailings stacking is increasingly gaining industry attention following heightened regulatory scrutiny surrounding wet tailings storage facilities globally.

Mining companies are facing growing pressure from regulators, insurers and investors to adopt safer tailings management methods following several major international tailings dam failures in recent years.

Clean TeQ Water believes its ATA platform offers mining operators a lower-cost pathway toward filtered tailings disposal compared with traditional high-cost pressure filtration systems.

The company also noted that filtered tailings solutions may improve water recovery rates for reuse in processing operations while potentially reducing the footprint required for tailings storage facilities.

Rasp Mine Expansion Adds Strategic Relevance

The Rasp Mine project itself also carries strategic relevance within the broader Broken Hill mining region.

Broken Hill Mines is currently working to increase processing throughput at the Rasp operation while also progressing development activities and exploration programs.

The company additionally plans to advance the restart of the nearby Pinnacles Mine, with ore from that operation expected to be processed through the Rasp facility.

Against this backdrop, the tailings dewatering plant becomes an important infrastructure component supporting future production expansion plans.

For Clean TeQ Water, the project provides another operational reference point for its ATA technology within a producing mine environment.

The company has stated that the ATA system deployed at Rasp has undergone extensive laboratory testing and pilot work specifically using Rasp Mine tailings.

According to the announcement, the testing process generated filtered tailings outcomes that exceeded the moisture content targets required by the mine.

Clean TeQ Water Continues Expanding Environmental Technology Focus

Clean TeQ Water is headquartered in Melbourne and focuses on water treatment, mine tailings management and resource recovery technologies.

The company operates across several sectors including water recycling, wastewater treatment, lithium production support and mine rehabilitation solutions.

Its operations and partnerships span multiple international regions, including Australia, Europe, Asia, Africa and Latin America.

Over recent years, tailings management has emerged as an increasingly important thematic area across the mining sector as operators seek technologies capable of balancing operational efficiency, environmental compliance and water conservation.

The latest contract win may therefore be viewed by investors as part of a broader commercialisation pathway for Clean TeQ Water’s mining-related technologies.

The company’s ability to convert pilot testing and technical studies into operating project agreements remains a closely watched Factor for the market.

Market Reaction Reflects Positive Contract Sentiment

The modest rise in Clean TeQ Water’s share price following the announcement suggests investors viewed the contract update favourably, particularly given the combination of construction revenue potential and the possibility of longer-term recurring income through reagent supply and technology licensing.

The project also expands deployment of Clean TeQ Water’s proprietary ATA platform at a producing Australian mine operation, which may strengthen future commercial positioning for similar opportunities within the mining sector.

With the global mining industry continuing to evaluate alternatives to conventional wet tailings storage methods, investors are likely to monitor how successfully the company converts additional project discussions into commercial contracts over the coming periods.
