Savannah Resources Plc engages in the exploration and development of lithium deposits, primarily through its 100% owned Barroso Lithium Project in northern Portugal, Europe's largest spodumene lithium resource comprising multiple deposits including Grandao, Reservatorio, Pinheiro, NOA, and Aldeia. The company advances a conventional open-pit mine and concentrator operation designed to produce approximately 190,000 tonnes per annum of spodumene concentrate, sufficient for around 500,000 electric vehicle battery packs annually; it maintains active programs for resource delineation, geotechnical drilling, environmental monitoring, and stakeholder engagement to support Europe's battery value chain and energy transition goals. Founded in 2010 and headquartered in London, United Kingdom, with key operations in the Boticas region of northern Portugal near Porto and the Leixoes port, Savannah targets the European Union market as a critical raw materials supplier.
In June 2024, AMG Critical Materials N.V. invested GBP 16 million via share subscription, becoming Savannah's largest shareholder with a 15.77% stake, alongside heads of terms for an offtake of up to 90,000 tonnes per annum of spodumene concentrate for 10 years, a cooperation agreement for joint studies on feldspar/spodumene processing and lithium carbonate refining in Portugal or Spain, and support in securing full project financing. The project received European Commission 'Strategic Project' designation under the Critical Raw Materials Act in 2025, with ongoing due diligence for a potential German government-backed US$270 million loan guarantee via KfW IPEX-Bank and Euler Hermes. As of November 2025, Savannah progresses acquisition of the adjacent Aldeia Mining Lease adding a JORC resource of 3.5 million tonnes at 1.30% Li2O and exploration targets, advances its Definitive Feasibility Study toward completion in 2026 with first production targeted for 2027, and reports cash reserves of approximately GBP 21 million following a recent oversubscribed fundraise.
