Ascension Selective Recovery Programme for Critical Mineral Extraction

pre-commercial validation

Ascension's Selective Recovery programme is an innovative geothermal mineral recovery project that targets critical minerals directly from volcanic rock deposits using naturally occurring geothermal heat. The approach avoids surface excavation and high-temperature chemical processing, aiming to reduce environmental impact compared to conventional mining methods. The programme involves geological characterisation, subsurface access, geothermal heat utilisation, targeted solution chemistry, solution recovery, and field validation to demonstrate recovery rates and environmental performance at operational scale.
