The Gravelotte emerald mine, which was in operation from 1929 to 2002 and was reportedly the world’s biggest emerald mine in its heyday, is once again in production, albeit initially on a very small scale. The company behind the revival of the mine is LSE-listed junior GEM Resources (previously URA Holdings). ARTHUR TASSELL recently spoke to its CEO, DR BERNARD OLIVIER, to learn more about the operation, which is South Africa’s only producing emerald mine.
The mine is located near the town of Gravelotte in Limpopo Province, approximately 50 km west of Phalaborwa and close to the well-known Consolidated Murchison antimony/gold mine. The emeralds are primarily found in biotite schist, which is part of the Gravelotte formation.
