www.aquarry.earth ↗Turns flooded abandoned open-pit mines (pit lakes) into durable carbon sinks by dissolving alkaline minerals so the water absorbs CO2 and precipitates it as limestone-like minerals, while remediating mining-influenced water and recovering metals from tailings.

The Current Angle
A carbon removal play that sells to the mining industry's balance sheet as much as to carbon buyers: every pit lake is a closure liability, and Aquarry pitches lower closure costs and carbon-tax exposure plus recovered metals, with up to tens of millions of tonnes of CO2 storage per site and thousands of candidate sites globally. Co-founder Spencer Whitman is in NLR's West Gate lab-embedded entrepreneurship program in Golden.
