METLEN Energy & Metals has secured a long-term agreement to supply around 25% of its planned gallium production to an undisclosed leading U.S. technology company, giving one of Europe’s most significant domestic gallium projects a commercial anchor ahead of the start of production.
The agreement covers gallium that will be produced at METLEN’s Aluminium of Greece complex in Agios Nikolaos and represents the company’s first commercial contract for the metal from the planned facility. METLEN has not disclosed the customer’s identity, contract length, pricing structure or detailed product specifications, leaving investors without enough information to calculate the deal’s precise revenue contribution. Nevertheless, the volume committed under the agreement is significant. METLEN is targeting annual gallium production of approximately 50 tonnes, meaning the U.S. technology customer could take around 12.5 tonnes per year once the facility reaches its planned capacity. Gallium production is expected to start in 2027, with the operation reaching full-scale output in 2028.
€295.5 Million Investment Links Gallium to Aluminium Production
The gallium project forms part of a broader €295.5 million investment programme at METLEN’s Greek industrial complex. The investment is expected to lift annual bauxite production to approximately 2 million tonnes, while alumina capacity would rise from 865,000 tonnes to 1.265 million tonnes per year.
Gallium will be recovered as a by-product of the alumina-refining process, giving METLEN an important cost and infrastructure advantage over a conventional standalone mining project.
The company does not need to develop a dedicated gallium mine or construct an entirely new processing operation. Gallium is already present in suitable Greek bauxite and can be recovered from the Bayer-process stream at an established aluminium complex. That integrated model is central to the project’s commercial proposition. Existing power infrastructure, port facilities, laboratories, technical personnel and processing assets can support the new operation, potentially lowering the incremental capital requirements associated with gallium production.
Public Financing Provides a Strong Foundation
The project has also attracted an unusually substantial package of European public support. METLEN’s development has been recognised as a Strategic Project under the EU Critical Raw Materials Act and has received approval for approximately €118 million in grants and tax incentives. The project is additionally supported by around €90 million in European Investment Bank financing. Together, those instruments represent roughly 70% of the disclosed investment budget, although the individual forms of support have different structures, conditions and financial implications.
The newly signed U.S. supply agreement fills a different role. Public funding can reduce project risk, support infrastructure and improve financing conditions, but it does not by itself demonstrate that an industrial customer is prepared to purchase the resulting material. The offtake agreement provides that missing commercial validation. For METLEN, the contract indicates that a major technology company has sufficient confidence in the project’s product quality, qualification process and future production capability to commit to material before commissioning.
China Dominates Gallium Supply
The strategic importance of the agreement is closely linked to the structure of the global gallium market. China dominates primary gallium supply, while export restrictions introduced in 2023 heightened concerns among manufacturers that depend on the metal and related semiconductor materials.
Gallium is particularly important for the production of gallium nitride and gallium arsenide semiconductors, which are used in radar, satellite communications, radio-frequency equipment, power electronics, data-centre infrastructure and advanced defence systems. The growing deployment of high-performance electronics is adding to the strategic importance of secure gallium supplies. A U.S. technology company agreeing to purchase approximately one-quarter of METLEN’s planned production could therefore have significance beyond the initial 12.5-tonne annual commitment.
The customer could potentially serve as a reference point for future qualification by other buyers in the semiconductor, telecommunications, defence and advanced electronics sectors.
Pricing Remains a Major Unknown
The contract does not yet provide enough information to establish the project’s expected profitability. Gallium markets are relatively opaque compared with major industrial metals such as copper, aluminium and zinc. Prices can vary according to purity, physical form, customer qualification, supply availability and geopolitical conditions. METLEN has not said whether the agreement includes fixed pricing, market-linked adjustments, minimum purchase commitments or mechanisms to protect against rising production costs.
Those provisions could have a substantial impact on the project’s economics. A technology customer seeking supply diversification may place a premium on non-Chinese production, but the extent of that potential premium cannot be established without the contract’s commercial terms. For now, the most important development is that METLEN has secured a buyer for 25% of planned output, rather than the exact financial value of those tonnes.
From Policy Project to Commercial Development
The agreement changes the character of the gallium development. METLEN now combines EU strategic-project status, public financial support, EIB debt financing, an existing bauxite and alumina industrial platform and a committed customer for one-quarter of future production. That combination makes the project considerably more advanced commercially than a critical-minerals development based solely on government targets or projected demand.
The company must still demonstrate that the operation can be built on schedule, commissioned successfully and operated consistently at the required purity and quality levels. The remaining 37.5 tonnes of annual planned production will also need to find customers if METLEN is to maximise the project’s commercial potential. That creates an opportunity to develop a diversified customer base across European and international technology, defence and industrial markets without becoming overly dependent on a single buyer.
Europe Seeks Greater Critical-Mineral Independence
The gallium project fits directly into Europe’s broader attempt to strengthen domestic supplies of strategically important raw materials. Gallium illustrates why the European critical-minerals challenge is not simply about opening new mines. Because the metal is commonly recovered as a by-product, existing European processing infrastructure can become a source of additional critical-material supply.
METLEN’s approach effectively adds a high-value technology material to an established alumina operation.
For the European Union, this could provide a model for extracting more strategic materials from industrial processes already operating within the bloc, reducing dependence on imported refined products without necessarily requiring a completely new mining complex. The commercial contract with a U.S. technology company also introduces a transatlantic dimension, linking European processing capacity with American technology demand.
Greece Gains a New Role in Critical Raw Materials
For Greece, the project could expand the strategic importance of its existing aluminium industry. The Aluminium of Greece complex has historically centred on bauxite, alumina and primary aluminium. Gallium adds another product with direct connections to advanced electronics, defence, communications and energy technologies.
Its importance is therefore disproportionate to the relatively small physical volumes involved. The project also demonstrates the potential value of maintaining sophisticated metallurgical processing and refining capabilities in Europe. Rather than exporting raw materials for further processing elsewhere, Greece could capture additional value by recovering critical metals domestically.
METLEN Gallium Project Reaches a New Commercial Stage
METLEN’s U.S. supply agreement represents an important transition from policy-backed development to commercially anchored critical-mineral production. The company has secured a customer for approximately one-quarter of its expected gallium output before the facility begins production, while European institutions have already provided strategic recognition and financial support.
The decisive tests now shift to construction, commissioning, product qualification and reliable commercial-scale production. If METLEN successfully delivers those milestones, its Greek operation could become an important new source of European gallium and establish a rare example of critical-material production being integrated directly into an existing aluminium and alumina value chain. For investors and industrial customers, the next question is no longer simply whether Europe needs alternative gallium supply. It is whether METLEN can convert its €295.5 million industrial investment, public-sector backing and newly secured U.S. offtake into consistent production at competitive economics.
