Introduction - Alignment with Sustainable Development Goals 1. In Focus: 21st Century Mining at Kassandra Mines

While producing the materials necessary for modern life, mining impacts economies, societies and the environment. However, contrary to the past, a responsible mining company in the 21st Century seeks to secure the well-being of the environment and local communities at each stage of a mining life cycle (from exploration to reclamation) and aims to create value for Stakeholders beyond the life of its projects.

Kassandra Mines’ Environmental Impact Assessment is approved by the Greek Government

Mining rights and Kassandra Mine facilities are transferred to Hellas Gold

Investment in Olympias stopped due to local community reactions and a Council of State’s negative decision

Exploitation rights and mining facilities are transferred to TVX Hellas, a subsidiary of the Canadian TVX Gold

Exploitation of the mixed sulfide mine begun in Olympias

The Hellenic Company of Chemical Products & Fertilizers S.A. succeeded the French-Ottoman exploitation and focused its activities on Stratoni

The name ‘Kassandra Mines’ first appeared with mining rights granted by the Ottoman Empire to the FrenchOttoman S.A.

12 villages in the area (Mantemochoria) acquired the right to manage silver mines on their own through a Mining Association

before 15th century

• 15th century: Approximately 500-600 zinc and lead processing furnaces were active • Byzantine period: Exploitation of mines begun once again • Roman period: Mining activities continued • 6th century BC: Mines were used as main financial supporter for the Macedonian Kingdom and Alexander the Great’s campaigns

Mineral analysis needs a lot of time and expensive procedures by specialized laboratories on many drill cores for several weeks to evaluate a mine’s potential and identify suitable positions for excavations. It is estimated that only 1 in a 1,000 mine explorations provides a positive result.

Amended Transfer Agreement and New Investment Plan signed and ratified by the Greek Parliament, which will lead to significant positive benefits for the local, regional and national economy

Used SkyTEM technology to map geological data through sensors and equipment from helicopters, which ensures minimal or zero surface and natural landscape intervention compared to traditional ground-based exploration methods, as part of the European Smart Exploration project to address exploration challenges of vital mineral resources for the European Union’s economy and technological advancement

Received permit for installation of upgraded electrical substation and construction of support facilities in Olympias and Skouries

Completed tailings re-treatment

Began refurbishment of underground mine and existing mill in Olympias

Began tailings clean up and re-treatment

Eldorado Gold acquired ownership of Hellas Gold

Initiated participation in the European X–Mine research project, which combines X-ray based technologies and 3D modeling technology to identify location of next excavations, without the need to send samples for testing, extended explorations and blasting, and therefore potentially reduce transportation costs by 20%, waste rock by 7% and energy consumption and CO2 emissions by 10-30%. We are one of the only 4 mining companies in Europe participating in this breakthrough exploration research project, even though at the moment there is no implementation plan for Greece.
