Aquarry provides mining operators with a technology that treats water‑filled pit lakes by dissolving alkaline minerals to capture CO₂ and precipitate limestone, simultaneously reprocessing adjacent tailings and waste rock to recover critical metals. The solution reduces closure and carbon‑tax costs, improves water quality, and generates sellable carbon credits, while the company supports feasibility studies, pilot testing, full‑scale design, and carbon‑credit registration.

Problem
When open‑pit mines are closed they often fill with water, forming pit lakes that become long‑term environmental liabilities and generate ongoing closure and carbon‑tax costs for mining companies. These lakes are typically isolated from tailings and waste rock, which may still contain valuable critical metals that remain unexploited.
Solution
Aquarry offers a technology that treats pit‑lake water by dissolving alkaline minerals, enabling the water to absorb CO₂ and precipitate limestone‑like solids that settle and fill the lake, improving water quality and reducing the physical liability. Simultaneously, the process reprocesses adjacent tailings and waste rock to extract critical metals at costs lower than conventional tailings recovery. The captured CO₂ is quantified, validated, and can be sold as carbon credits, providing an additional revenue stream. Aquarry guides mining operators through feasibility assessment, pilot testing, full‑scale design, and implementation, while handling carbon‑credit registration and optional sales.
Target Audience
Primary customers are mining companies that own or operate closed‑pit sites with water‑filled pits and associated tailings or waste rock, seeking to lower closure expenses, mitigate carbon‑tax liabilities, and monetize recovered metals and carbon credits.
Features
- Alkaline mineral dissolution in pit‑lake water to promote CO₂ uptake and in‑situ limestone precipitation
- Integrated metal recovery from tailings and waste rock using the same remediation workflow
- Pilot‑scale testing and data collection to support permitting and performance validation
- Full‑project design using existing EPC equipment familiar to mining operators
- End‑to‑end carbon‑credit validation, registration, and optional market sales services
- Ownership of recovered metals and generated carbon credits retained by the mining client
