Restoration of Old Olympias Arsenopyrites Concentrate Storage Area (Former METBA Plot)

Abstract

The area of the old arsenopyrites concentrate storage area is located at the Olympias Mining Facilities. The area was formed in the 1970s as a temporary storage area for the produced concentrate of gold-bearing arsenopyrite of Olympias. The total area is 11 hectares, and in the 1980s, the concentrate was removed from the site and arsenopyrite residues, which remained on the deforested surface, were major sources of pollution of the surface and ground waters of the wider area. The remediation and restoration works of this area were initiated by Hellas Gold as a priority immediately after taking over the Kassandra Mines property. After the restoration of the area, a nursery was installed with more than 1,000,000 plants.
