Portugal’s Barroso Lithium Project, developed by Savannah Resources, has emerged as one of the first large-scale mining developments to test whether the European Union’s Critical Raw Materials Act (CRMA) can translate strategic policy into domestic mineral supply while maintaining environmental and social permitting standards. As one of the European Commission’s designated Strategic Projects, Barroso is progressing toward key regulatory and financing milestones that will determine whether it can begin production in 2028.
The hard-rock spodumene project, located near Boticas in northern Portugal close to the Spanish border, is positioned by Savannah as the largest conventional lithium project in Europe. Its progress is being closely watched by governments, investors, battery supply-chain participants and local communities, with the project becoming a focal point for debates over permitting, environmental oversight and domestic critical mineral production.
Development timetable moves toward investment decision
Savannah is targeting completion of the Definitive Feasibility Study (DFS) and the RECAPE environmental licence compliance process in July 2026. The company expects to obtain its final environmental licence during Q3 2026, followed by a Final Investment Decision (FID) before the end of the year.
Subject to financing, permitting, commercial partnerships and construction execution, the company continues to target commissioning and first production in 2028.
The project is advancing during a markedly different lithium market from the conditions seen in 2021 and 2022. Lower lithium prices, evolving battery chemistries, expanding Chinese conversion capacity and tighter capital markets have increased investor focus on project financing, permitting, downstream processing and customer qualification.
Resource base and production plan
Savannah owns 100% of the Barroso project. The current mineral resource totals 39 million tonnes containing 411,900 tonnes of Li₂O, equivalent to approximately 1.019 million tonnes of lithium carbonate equivalent (LCE) across five orebodies. Around 68% of the ore and contained lithium oxide is classified within the measured and indicated categories.
The planned operation is designed to produce approximately 190,000 tonnes per year of spodumene concentrate, providing sufficient lithium to supply batteries for around 500,000 electric vehicles annually.
The project also benefits from its location less than 300 kilometres from five Atlantic deep-water ports, providing logistics access for concentrate shipments. Savannah has stated that it intends to operate using 100% renewable electricity, reflecting Portugal’s high share of renewable power generation.
Government backing and CRMA designation
Barroso received further support in January 2026, when the Portuguese government approved a development grant of up to €110 million.
Although the grant does not fully finance project development, it provides public-sector support intended to strengthen project economics, reduce funding requirements and support financing discussions.
The project was also granted Strategic Project status under the Critical Raw Materials Act in 2025, providing access to accelerated policy support, greater permitting visibility and potential financing opportunities linked to Europe’s critical minerals strategy.
Permitting remains central despite strategic status
The project’s CRMA designation has not removed environmental or legal challenges. Local organisations and environmental groups have opposed the mine, raising concerns relating to water resources, biodiversity, traditional agriculture, landscape values and community impacts in the Covas do Barroso region.
Campaigners have challenged the European Commission’s decision to include Barroso on the Strategic Projects list, arguing that environmental and safety issues were not sufficiently addressed during the sustainability assessment. The project has also faced criticism concerning public access to environmental information during the licensing process. These legal proceedings continue alongside the project’s regulatory review, highlighting that strategic designation does not replace environmental permitting or community consultation requirements.
Engineering work supports environmental approval
Savannah continues to advance technical and environmental studies supporting the permitting process, including geotechnical investigations, metallurgical testing, noise assessments and RECAPE documentation. The company has also begun making initial capital equipment commitments while progressing engineering work.
Savannah intends to complete both the DFS and RECAPE submission using existing technical data, with additional information expected to be incorporated during subsequent engineering, detailed design and financing stages. The company is seeking to maintain its development schedule as European battery manufacturers and downstream processors continue evaluating future domestic lithium supply.
Downstream processing remains a strategic consideration
Barroso is designed as a spodumene concentrate producer rather than a lithium hydroxide refinery. As a result, the project’s long-term strategic significance depends not only on mine development but also on downstream conversion into battery chemicals within Europe or through other processing arrangements.
Potential sales routes include supplying future European lithium conversion facilities, other regional customers or export markets through Portugal’s Atlantic ports. Future strategic partnerships and offtake agreements are expected to determine how the concentrate is integrated into the battery materials supply chain.
Financing influenced by market conditions
The current lithium price environment has increased scrutiny of development-stage projects, particularly those requiring significant capital investment. Barroso combines several characteristics that distinguish it within the European pipeline, including a conventional hard-rock spodumene deposit, CRMA Strategic Project designation and direct financial support from the Portuguese government.
At the same time, the project must meet European environmental requirements, permitting standards and community expectations while competing against established hard-rock lithium producers internationally. The financing case therefore depends not only on resource quality but also on security of supply, logistics, regulatory certainty, carbon profile, downstream integration and customer commitments.
Project milestones will determine next phase
Portugal continues to position itself as a participant in Europe’s battery materials industry through renewable power resources, Atlantic logistics infrastructure and domestic lithium development. Barroso has become one of the country’s highest-profile mining developments, with national industrial objectives existing alongside continued local concerns regarding land use, water management and environmental protection.
Upcoming milestones—including completion of the DFS, RECAPE process, final environmental approval, strategic partnerships, project financing and FID—will determine whether the project proceeds toward its planned 2028 production schedule.
The project’s combination of 39 million tonnes of resources, €110 million in state support, CRMA Strategic Project designation and ongoing environmental and community scrutiny has made Barroso one of Europe’s most closely watched lithium developments as the region seeks to expand domestic critical mineral supply.
