BARROSO LITHIUM: THE PORTUGUESE PROJECT THAT CAN REDEFINE THE INDUSTRIAL FUTURE OF EUROPE
n this context of great geopolitical tension, of international competition for access to minerals, and with the urgency of fighting climate change, an opportunity arises for Portugal.
The Barroso Lithium Project, developed by Savannah Resources in the municipality of Boticas, has increasingly established itself as one of the most important European projects linked to the energy transition. Today, it represents a hope of rebirth for a region so often forgotten and for the many families who have seen their loved ones depart over the years.
More than a lithium mine, the Barroso Lithium Project represents an opportunity for Portugal to participate in one of the most strategic value chains of the 21st century: the production of batteries for electric vehicles, energy storage, and other technologies associated with the decarbonization of the economy.
Designed on the basis of the most demanding environmental assessments in the world, and subject to unprecedented public scrutiny, the project can also be seen as a lesson on the challenges of developing industrial and mining projects in the Europe of today.
A European resource in a global context
The strategic relevance of the project stems, from the outset, from its location and scale.
Lithium is considered today one of the essential raw materials for the electrification of mobility and for the storage of renewable energy. Currently, a large part of world production is concentrated in countries such as Australia, Chile, Argentina, and China. Processing and refining, on the other hand, are heavily dominated by Chinese industry.
Few in Brussels — and, in truth, across the entire continent — would dispute the importance of raw materials. However, the challenge remains as to whether Europe will be able to transform this awareness into new industrial capacity, rapidly and at scale.
The technologies that will shape the future of Europe all depend on materials frequently produced in other parts of the world. Artificial intelligence, semiconductors, defense systems, renewable energy, and advanced communication systems depend on elements that easily pass unnoticed — until the security of supply chains becomes uncertain.
In an increasingly complex geopolitical context, the European Union seeks to reduce this external dependence by developing its own sources of supply. It was precisely for this reason that Brussels classified the Barroso Lithium Project as one of the strategic projects under the Critical Raw Materials Act (CRMA), the new European framework designed to reinforce strategic autonomy in critical raw materials. It was also under this logic that lithium was identified by Mario Draghi as the greatest potential for Portugal in the process of reindustrialization of Europe in the famous Draghi Report.
An opportunity for Portugal
The project is based on what is the largest lithium spodumene deposit in Western Europe and is slated to be the second project to enter production, in 2028, after the Keliber project that came into operation in this year of 2025 in Finland.
The Definitive Feasibility Study (DFS), recently concluded, confirms an initial probable reserve of around 20 million tonnes of ore, sufficient to support an operation with an initial useful life of 14 years. During this period, the production of approximately 2.56 million tonnes of spodumene concentrate is projected. That quantity would be sufficient to supply raw material for more than seven million batteries destined for electric vehicles. Another dimension that became clear upon publication of the DFS points to the potential for future expansion that could significantly prolong the project’s useful life for decades.
It is important to emphasize that the DFS is one of the most relevant studies in the process of developing a plant and mine associated with mineral resources, as these are studies conducted at a very advanced stage. It is estimated that only one in every thousand mining development projects in the world reaches such an advanced stage, which confirms the quality of the work already done and reinforces the capacity of the Barroso Lithium Project to deliver value.
The realization of the Barroso Lithium Project coincides with a moment in which Portugal seeks to position itself in industrial sectors of greater added value.
This intention became clear at the beginning of the year when the Portuguese Government, through AICEP, granted financial support to companies in the battery value chain, aiming at the consolidation of structural projects in Portugal. The Barroso Lithium Project was one of the selected projects, receiving €110 million in support against investment for being identified as an anchor project that will have the power to attract other industry players who wish to be close to the raw material.
Historically, the country has had limited participation in the supply chain of energy technologies. However, the energy transition is creating new opportunities for countries capable of securing raw materials, renewable energy, and regulatory stability.
Beyond lithium, this project also represents an opportunity for other industries, particularly through the annual production of approximately 600,000 tonnes of minerals for the ceramics industry and the insulation industry. These are two industries that are important in Portugal, in particular, and in the Iberian Peninsula, in general.
Products such as quartz, mica, or feldspar have already been the subject of agreements with partners who will place these products with the many ceramic factories that Portugal has, reviving traditional industries in the country.
For a region marked by decades of population loss and low private investment, the project also emerges as an opportunity for economic revitalization. The project foresees a total of 500 industrial jobs, between direct and direct subcontracted roles, to which an estimated 1,000 indirect and induced jobs will be added when the mine and plant are in operation. In terms of taxes, fees, or royalties for Portugal, the contribution to the national economy will be in the order of €700 million. As in other municipalities where mining projects are developed, such as Castro Verde or Aljustrel, the success of the project will allow the municipality of Boticas to become more prosperous, more active, and more attractive for a more skilled generation that will bring its energy back to Barroso.
The paradox of the energy transition
The debate surrounding the Barroso Lithium Project illustrates one of the greatest paradoxes of our time.
Society demands more electric vehicles, more renewable energy, and lower carbon emissions. However, these technologies depend on increasing volumes of raw materials such as lithium, copper, nickel, manganese, or rare earths. Concepts like Energy Transition and Energy Independence become common in discussions about the future, sometimes with little attention given to how to make them a reality.
For years, much of the extraction of the materials needed for this authentic revolution occurred outside Europe, often in countries with environmental, social, or labor standards different from European ones. But today that view has changed, and it is increasingly accepted that the answer lies in developing a portion of these supply chains within Europe, subject to demanding European environmental standards.
It is precisely in this context that projects like Barroso acquire strategic significance.
The central question is no longer merely whether Europe needs lithium. The political consensus suggests that it does. The real discussion becomes where and how that lithium will be produced. The Barroso Lithium Project is developed within the European Union, in a transparent manner, in continuous interaction with the national and local entities responsible for its monitoring. At the national level, the project responds to the requirements of the Portuguese Environment Agency (APA), the Institute for Nature Conservation and Forests (ICNF), the Directorate-General for Energy and Geology (DGEG), and so many other entities involved in its supervision.
At the local level, the Project is today better understood by more and more people in the communities around the Project, which has resulted in an increasingly greater acceptance of the Project and its benefits. More and more local people work in Savannah’s team — already numbering around 30 today — or collaborate indirectly in daily field operations, at the company’s office in Boticas, or at the Geology Centre located in Carreira da Lebre. More than 10 cooperation agreements have already been signed with local entities, from small associations to sports clubs, parish councils, community land management boards (baldios), and various regional entities — a symbol of ever greater acceptance in the region and of the desire of the people of Boticas to bring progress to their land, in a balanced and sustainable way.
The future starts now
The responsibility of undertaking an industrial project of this dimension, in this region, is great, and requires a constant presence in the territory and interaction with the various local and national actors, in order to ensure that the Project delivers wealth and development while contributing to returning pride and a sense of belonging to the people of Barroso.
The Barroso Lithium Project is currently at a decisive stage.
The conclusion of the Definitive Feasibility Study represents an important milestone, by confirming the technical and economic feasibility of the enterprise and its competitive positioning on an international scale. Projected operational costs place the project among the most competitive in the sector, revealing a very strong project, even compared to some of the best projects in the world, due to the degree of competitiveness and product quality.
At the same time, European recognition as a Strategic Project reinforces its relevance for EU industrial policy, just as the support of the Portuguese State symbolizes the clear strategy of national reindustrialization and the development of a lithium battery value chain that will place Portugal in a leadership position worldwide.
In the coming months, the focus will be on the different possibilities to secure financing, conclude the remaining regulatory processes, maintain dialogue with local communities, and transform years of studies and planning into an operational reality. The start of production is planned for the end of 2028, with the construction of the various planned infrastructures in the period until then.
One conclusion seems difficult to dispute: few industrial initiatives in Portugal concentrate simultaneously such immense economic, energy, environmental, and geopolitical relevance.
In Barroso, more is at stake than the future of a mining project. At stake is also part of Europe’s answer to the question of whether the energy transition can be built with resources produced in Europe itself — in a transparent and sustainable way, with high quality of execution and environmental and social scrutiny — or whether it will remain dependent on external supply chains.
