Cosmos Advances Lithium Tech Testing in Bolivia, Reports High-Grade Uranium in Canada
Cosmos Exploration has progressed its lithium brine extraction testing in Bolivia using Vulcan Energy’s VULSORB® technology and reported promising uranium mineralogy results from its Canadian projects, supported by a $1.25 million capital raise.
- Completed $1.25 million placement to support EAU Lithium acquisition and working capital
- Synthetic brine testing underway in Germany using Vulcan Energy’s VULSORB® A-DLE technology
- 5m³ of Bolivian bulk brine samples shipped for advanced lithium extraction testing
- High-grade uranium mineralogy confirmed at Nut Lake South Project in Nunavut, Canada
- Cash position of $811,000 with ongoing exploration and corporate expenditures
Strategic Capital Raise and Lithium Testing Progress
Cosmos Exploration Limited (ASX: C1X) has fortified its financial position with a $1.25 million placement, including a $250,000 commitment from directors pending shareholder approval. This capital injection underpins the company’s exclusive option to acquire EAU Lithium Pty Ltd and supports ongoing working capital needs.
EAU Lithium has initiated synthetic brine testing at Vulcan Energy Resources’ facility in Germany, employing Vulcan’s proprietary VULSORB® Adsorption-Type Direct Lithium Extraction (A-DLE) technology. This bench-scale testing replicates the complex chemistry of Bolivian brines from Salar de Coipasa, Salar de Empexa, and Salar de Pastos Grandes, providing early insights into the technology’s compatibility and efficiency ahead of bulk sample processing.
Bulk Brine Samples and Technology Validation
In a significant logistical effort, 5 cubic metres of bulk brine samples from the three Bolivian salars have been shipped to Germany for detailed analysis and process optimisation. These salars lie within or near the Lithium Triangle, a region that holds over half of the world’s identified lithium resources, with Bolivia alone estimated to contain 23 million tonnes of elemental lithium.
The testing program aims to overcome historical challenges posed by Bolivia’s high-magnesium brines, which have limited the viability of conventional lithium extraction methods. Vulcan’s VULSORB® technology offers a potentially more sustainable and scalable solution, aligning with Bolivia’s national lithium strategy and opening pathways toward industrialisation agreements.
Uranium Exploration Advances in Canada
Beyond lithium, Cosmos has reported encouraging results from its uranium exploration in Nunavut, Canada. At the Nut Lake South Project, micro-XRF mineralogical analysis of a high-grade uranium sample (1.24% U₃O₈) confirmed the presence of uranophane and associated sulphides, mirroring the mineralogical signature of the nearby Angilak (Lac 50) deposit. This supports the company’s geological model targeting basement-hosted unconformity-style uranium systems.
The Gyrfalcon prospect within Nut Lake South is now identified as a high-priority target, reinforcing Cosmos’ strategy to advance early-stage exploration in a district with significant uranium potential.
Financial Position and Outlook
Cosmos ended the quarter with $811,000 in cash, following exploration and corporate expenditures totaling approximately $206,000. The company continues to manage its resources prudently while advancing critical testing and exploration milestones.
Strategic developments in the lithium sector, including Rio Tinto’s recent A$10 billion acquisition of Arcadium Lithium and China’s tightening of lithium technology exports, underscore the growing importance of Western-developed direct lithium extraction technologies like VULSORB®. Cosmos’ partnerships and technology focus position it well to capitalize on these industry shifts.
Bottom Line?
As Cosmos awaits synthetic brine test results and advances uranium exploration, its dual-commodity strategy could unlock significant value amid evolving global lithium and uranium markets.
Questions in the middle?
- Will the synthetic brine testing validate Vulcan’s VULSORB® technology for Bolivia’s high-magnesium brines?
- How soon can Cosmos secure industrialisation agreements with Bolivia’s government following test outcomes?
- What are the next exploration steps and potential resource upgrades at the Nut Lake South uranium project?
