Investors
Geo40 is supported by a loyal group of over 350 investors. Their belief in the Company has permitted it to occupy a unique space and achieve several world firsts.
In response, our job is to leverage this technology globally to provide attractive returns to shareholders.
Geo40 commissioned its first commercial-scale silica project in February 2021. Production from our Northern plant started in 2021, whilst a sales pipeline was gradually built up, and the silica asset became profitable during 2025, whereby our sales demand currently matches our production.
While the Company’s offer around silica recovery is now becoming understood in the geothermal community, the Company’s work on lithium recovery is making it more widely relevant.
Through 2025, the company reinvented its silica recovery flowsheet to improve financial returns for asset owners. The company is now marketing this new solution to the global geothermal community.
In 2025, the company also completed development of its proprietary direct lithium extraction (DLE) technology in 2019. Since that time, the company has piloted the technology across the world and in 2025, constructed a 300tpa LCE (lithium carbonate equivalent) pre-commercial demonstration plant. This plant will undergo testing in New Zealand in 2026, ahead of a likely offshore deployment.
