The Greek mining sector is undergoing a structural transformation that goes far beyond traditional mining activities, according to Miningsee, a website specializing in energy and mining issues in Southeast Europe.
While in the past it was primarily associated with gold, aluminum, and industrial minerals, the country is now emerging as a key European hub for critical raw materials, copper, and advanced metallurgical processing, driven by Europe’s urgent need to secure strategic supply chains for the energy transition and high-tech industry.
This development reflects a broader reality across Europe: the challenge is no longer just about access to mineral deposits, but also about controlling the refining, processing, and industrial conversion capacity that transforms raw materials into inputs for batteries, semiconductors, defense systems, and renewable energy infrastructure.
Metlen is leading the transformation
At the heart of this transformation is Metlen Energy & Metals, which has evolved into one of Europe’s most strategically important vertically integrated metallurgical companies.
The group has launched a major investment program exceeding €295 million at the Agios Nikolaos industrial complex, with the aim of increasing alumina production capacity to approximately 2 million tons per year.
This development positions Greece among Europe’s leading aluminum production centers, while strengthening its role in the continent’s industrial base.
A key strategic development within this expansion is the planned production of gallium, a critical metal used in semiconductors, radar systems, telecommunications, defense electronics, and advanced renewable energy technologies.
Its importance has skyrocketed following the export restrictions imposed by China, which highlighted Europe’s dependence on external supply chains. As a result, the Metlen project is increasingly viewed not merely as an expansion of metallurgical production, but as a strategic industrial infrastructure asset linked to Europe’s technological sovereignty.
Aluminum is becoming a strategic element of the European supply chain
Greece already hosts one of the most integrated aluminum ecosystems in Europe, linking bauxite mining, alumina refining, and aluminum production into a single industrial structure.
This vertical integration is becoming increasingly valuable as demand accelerates in key growth sectors such as electric vehicles, the expansion of power grids, offshore wind farms, the aerospace industry, and data center infrastructure.
Every aspect of the energy transition involves the use of aluminum. Power transmission grids, wind turbines, electric vehicle platforms, and storage systems rely heavily on lightweight and durable metals. As a result, the Greek aluminum industry is transitioning from a traditional industrial base to a strategic component of the European energy transition economy.
The Skouries project strengthens Greece’s position in copper and gold
In northern Greece, mining activity is also expanding through large-scale mineral resource development projects, particularly in copper and gold. The flagship project is the Skouries development, managed by Eldorado Gold as part of the broader Kassandra Mines complex in Chalkidiki.
With capital expenditures exceeding $1 billion, Skouries ranks among the largest mining projects currently under construction in Europe. Once operational, it is expected to be a major source of copper, a metal widely recognized as essential for electric vehicles, renewable energy systems, and the global expansion of infrastructure.
Demand for copper continues to rise due to electric vehicles, the modernization of power grids, energy storage systems, and digital infrastructure, such as data centers. This makes Skouries not just a mining project, but a critical element of Europe’s industrial resilience strategy.
From mining to integrated industrial systems
One of the most significant changes in the Greek mining sector is not taking place underground, but across the entire value chain. The sector is increasingly integrating mining, refining, energy systems, transportation, and industrial processing into a single structure. This reflects a broader European shift away from exporting raw concentrates and toward importing high-value-added processed materials.
Greece’s geographical location reinforces this transition. Located at the crossroads of Europe, the Eastern Mediterranean, and the trade routes connecting the Middle East, the country is evolving into a natural logistics and processing hub for critical mineral flows to Europe.
This is encouraging investment not only in mining projects but also in ports, industrial zones, storage infrastructure, and processing facilities designed to support regional supply chains.
Convergence of Critical Minerals and Industrial Decarbonization
Another emerging trend is the convergence between mining activity and industrial decarbonization. Greek industrial groups are increasingly integrating renewable energy sources, electrified production systems, and lower-carbon metallurgical processes into their operations.
For aluminum producers in particular, access to low-carbon electricity is becoming a competitive advantage. As the European carbon regulatory framework tightens and industrial buyers demand lower embedded emissions, producers who can demonstrate cleaner supply chains are expected to benefit from stronger pricing power and a better market position.
This trend is closely aligned with pan-European policy frameworks, such as the Critical Raw Materials Act, which emphasizes both supply security and the sustainability of industrial development.
