About EAU Lithium 

EAU Lithium, in strategic partnership with Vulcan Energy Resources and with a VULSORB® technology licence, are preparing – subject to successful negotiations – to support the Bolivian state, via Yacimientos de Litio Bolivianos (YLB), in developing future lithium production. 

Bolivia holds a significant portion of the world’s lithium reserves in high altitude – complex chemistry, brine lakes with social and environmental sensitivity. EAU Lithium, with Vulcan’s VULSORB® A-DLE technology believe they have the processing expertise to unlock the value of these deposits for all stakeholders whilst ensuring a minimal water and environmental footprint though a fully closed loop circuit. 

Cosmos merged with EAU Lithium in May 2026 in an all-scrip arrangement, bringing EAU Lithium’s executive team into the new merged company.
