- Vulcan has collected a bulk (10,000 litre) brine sample from a recently drilled geothermal well in the Upper Rhine Valley within 6km of Vulcan’s Ortenau Resource and license area.
- The bulk brine sample returned a high grade of 214 mg/L Li (n=1 analysis) and will be used in Direct Lithium Extraction (DLE) piloting test work.
- Vulcan now has brine data stretching back to 1980 showing remarkably consistent Li values in Upper Rhine Valley brine.
- Within Ortenau, Vulcan currently has an Inferred and Indicated JORC Resource Estimation of 12.86 Mt contained Lithium Carbonate Equivalent (LCE) at a grade of 181 mg/L Li, and Vulcan’s total Upper Rhine Valley Project has Inferred and Indicated Resources of 15.85
- Mt contained LCE at a grade of 181 mg/L Li of which 23% is in the Indicated category1, the largest lithium resource in Europe.
- The brine analysis also showed exceptionally low impurities (inc. Si, Mn, Fe) relative to other high-lithium geothermal brines worldwide, important for DLE performance.
- New data will be incorporated into Vulcan’s resource estimation update work later in the year, as part of Definitive Feasibility Study DFS) work for the Vulcan Zero Carbon Lithium® project.
