Geo40 develops unique, innovative technologies for mineral recovery from underground fluids for deployment at scale in the global transition towards cleaner energy and greener critical minerals. Geo40 is piloting its lithium extraction technology on a wide variety of brines across North America.  

Key features

  • Operates the world’s first large scale plant, in New Zealand, to commercially and sustainably recover nanoparticle colloidal silica products, with enhanced environmental credentials, from geothermal fluids

  • Emerging direct lithium extraction (DLE) technology, proven at lab and pilot scale and found to be applicable across a wide range of underground fluids globally

  • Strategic focus is on low-to-medium grade lithium-bearing oilfield and formation waters of North America

  • Vision Blue’s investment to contribute to in-field DLE piloting across North America during 2024 and subsequent scale-up to demonstration scale

  • Geo40 plans to prove its DLE technology in a methodical way, utilising the scale-up experience gained during the development of its silica recovery technology

End uses

  • Lithium is critical to green energy and emerging low-carbon transportation mobility, with key applications in lithium-ion batteries for EVs, grid storage and mobile devices

  • Colloidal silica enhances functionality across an ever-growing range of products and applications including speciality catalysts, coatings, adhesives admixtures, paper, cement and others
