EAU Lithium Advances Bolivian Lithium Plans with EUR 1 Million Pilot Plant Purchase

EAU Lithium Secures Proven Pilot Plant to Boost Extraction Capability

Cosmos Exploration Limited’s subsidiary EAU Lithium has taken a decisive step in its Bolivian lithium ambitions by formally committing to purchase Vulcan’s Adsorption-type Direct Lithium Extraction (A-DLE) Pilot Plant 4 (PP4) from Germany. The company has waived all remaining conditions precedent under the August 2025 Sale Agreement, locking in the EUR 1 million acquisition.

The PP4 unit, a German-built pilot-scale facility, represents a proven technology platform that has already successfully tested Bolivian brines. This acquisition grants EAU Lithium immediate access to validated hardware critical for optimising lithium brine processing under controlled industrial conditions, a key milestone for advancing the company’s proprietary VULSORB® extraction technology.

Strategic Partnership and Deployment Roadmap

This transaction deepens EAU Lithium’s strategic partnership with Vulcan Energy Resources, the German lithium and renewable energy pioneer behind VULSORB®. The pilot plant will initially be operated at Vulcan’s German facility to fine-tune direct lithium extraction performance on Bolivian brines before potential deployment in Bolivia.

Beyond technology optimisation, EAU Lithium plans to use PP4 as an educational platform to foster community engagement and technical skills transfer in Bolivia. The company aims to link this pilot program with local universities and academic institutions, supporting capacity-building in a region marked by complex brine chemistry and environmental sensitivities.

Cost-Effective Acquisition Supports Bolivian Lithium Ambitions

The deal structure reflects a cost-efficient approach, with an initial payment of EUR 125,000 already made and the balance of EUR 875,000 to follow. By acquiring an existing, operational pilot plant rather than building new infrastructure, EAU Lithium accelerates its timeline and reduces capital expenditure risks.

This move aligns with EAU Lithium’s broader strategy to collaborate with Yacimientos de Litio Bolivianos (YLB), the Bolivian state lithium company, to develop lithium production that balances economic opportunity with environmental stewardship. The company emphasises a closed-loop circuit design to minimise water usage and environmental footprint in Bolivia’s sensitive high-altitude brine lakes.

Positioning Amidst Growing Lithium Demand

Vulcan Energy’s Lionheart Project in Europe, which integrates lithium extraction with renewable energy, provides a technological foundation for EAU Lithium’s ambitions in South America. While Vulcan pursues its integrated carbon-neutral lithium production in the Upper Rhine Valley, EAU Lithium leverages VULSORB® technology to unlock Bolivia’s vast lithium reserves.

Following Cosmos Exploration’s recent merger with EAU Lithium in May 2026, this acquisition marks a tangible step towards commercialising lithium extraction in Bolivia, a region critical to the global battery supply chain. The pilot plant will be central to demonstrating scalable, environmentally responsible lithium processing.
