Exploration for CRM (Critical Raw Materials) in Old Boliden Mine Tailings
Hand drilling in Laisvall in the search for CRM (Soraya Heuss-Aßbichler and Ronald Arvidsson).
With a small tracked drill rig (1st picture) a number of drill cores were taken down to 20 meters. A hand drill (2nd picture) for sampling down to 7 meters was also used in the process.
We have reasons to believe that we might find Cobalt (Laisvall) and Germanium (Kristineberg), but the drill cores will be analysed for all CRM, SRM and REE in the upcoming weeks.
