Turning legacy mines from liabilities into assets.
A truly beneficial reuse of pit lakes that reduces both closure costs and tax liabilities.
Our solution
Aquarry enables mining companies to reduce closure costs and carbon tax liabilities while extracting additional metals from tailings and waste rock.
When open pit mines are closed they often fill with water, creating lakes. Tens of thousands of these pit lakes exist, but they are rarely converted for beneficial use. In the modern era, they represent major liabilities for mining companies.
Pit lakes are frequently located alongside tailings and waste rock which we can put to good use. Dissolving alkaline minerals in a pit lake makes the water absorb CO2, eventually forming limestone-like minerals which sink to the bottom of the pit. This process improves water quality and fills the pit back in, reducing the size of the liability.
Tailings and waste rock often contain valuable critical metals. In reprocessing these waste streams for lake remediation and CO2 removal, we enable recovery of metals at costs far lower than typical tailings recovery processes.
Our business
Own a pit lake? We’ll enable you to implement our technology to reap maximum benefits. We design it, you build it, and we take care of the legwork to register and sell your carbon credits.
01
Aquarry reviews key data from your site to estimate costs and feasibility.
02
You ship us materials to test in our lab, further refining our cost estimates.
03
We assist in running a limited-scale pilot on your site so you can see first-hand how the process works and collect permit-relevant data.
04
Aquarry works with you and key EPCs to design the full-scale project, using familiar equipment you already know how to run.
05
You implement and have full control of the project, with our dedicated support. Your metals and carbon credits are yours.
06
As you capture carbon, Aquarry takes care of validation, registration, and, if you choose to sell them, credit sales.
