The mining activity of the Kassandra Mines takes place in the wider area of NE Halkidiki, within the administrative boundaries of the Municipality of Aristotelis and with the operator being “HELLENIC GOLD SOLE ENTITY S.A. OF GOLD MINES AND INDUSTRY”. The project includes interventions of approximately 4,900 ha extending within a to-tal mining concession of 264,000 ha. The Olympiada Project concerns the development of an existing gold-bearing mine of mixed sulphide minerals, with a mining capacity of 12.38×106 tn of ore, exclusively by underground exploi-tation. Part of the above Project is also the environmental restoration of the old Olympiada mining tailings deposit area (Olympiada Tailings Lake). The area to be restored covers an area of 265 ha. In the context of the environ-mental restoration of Lake Telmaton, Olympiada, an Ecological Meta-Industrial Park will be studied and implement-ed, with the aim of creating terrestrial and wetland ecosystems, both to enhance biodiversity and to attract a new tourism model: naturalism, industrial archaeology and culture.
It proposes the formation of surfaces at a rate of 60% with earthworks (excavations – embankments – leveling), the formation of pedestrian routes (mild intervention) at a rate of 10%, and light architectural structures (estimated 500m2), the creation of a new habitat and the preservation and promotion of industrial fragments as sculptural ele-ments. Emphasis will be given to environmental awareness, sports and play.
The scope of the service consists of:
• Investigation of the creation of wetlands by exploiting surface and/or groundwater.
• Description of the current state of groundwater and surface waters in the tailings lake, including the upstream and downstream sections of the Mavrolakkas River, depending on the requirements.
• Investigation of the passage of a stream within the new Park and provision of hydraulic works to create wet-lands from the surface runoff of the Mavrolakkas River.
• Technical solution for the creation of wetlands in the tailings lake.
