Prospech Limited reported on initial investigation of historic drill core from the Korsnäs project. Inspection of the drill core revealed that historic sampling strongly focused on core with visible lead mineralization but overlooked zones of the potentially REE mineralized carbonatite. Following, Prospech’s geologists collected 65 core samples from the previously unsampled, prospective carbonatite.
Notably, the former Korsnäs lead mine left behind a tailings storage facility that is currently being investigated by the company as historic records indicate that rare-earth concentrates were not produced during the initial years of mine production.
Digitization of historical gravity data further revealed several linear gravity lows that show similar characteristics to the Korsnäs mineralization and thus represent favorable exploration targets.
