Savannah nears full Barroso lithium lease: resource, capex and pit design lens

30 Second Briefing
Savannah Resources is set to secure full ownership of the Aldeia C‑190 lithium lease at Barroso in northern Portugal, adding a JORC-compliant 3.5 Mt at 1.30% Li₂O on Block A, about 11% of the project’s global resource, for €3.25 million via staged payments to the Directorate General for Energy and Geology. Barroso, designated an EU strategic project, now totals over 39 Mt of high-grade spodumene and is planned as four open pits processing 1.5 Mt/year over 14 years, with break-even at roughly $600/t lithium. Production is targeted for 2028, but permitting and environmental licensing remain contentious in the Barroso World Heritage agricultural landscape.
Technical Brief
- Block A’s Indicated Resource will be directly incorporated into Savannah’s upcoming definitive feasibility study mine plan.
- Acquisition cost of €3.25 million is being met partly from an oversubscribed equity raise.
- Barroso’s strategic project status under EU rules is expected to unlock yet‑unspecified public funding support.
- CEO Emanuel Proença has publicly suggested a potential project valuation of about €1 billion on completion.
- Forecast output is framed as sufficient lithium for batteries powering roughly 500,000 electric vehicles annually.
- Portugal’s historic lithium production has focused on ceramics, with no existing large‑scale battery‑grade supply chain.
- Local opposition centres on Barroso’s 2018 World Heritage agricultural designation, with concerns over land, water and biodiversity impacts.
Our Take
With Barroso’s break-even cited at about $600/t lithium and a 14‑year mine life on a 20.5 Mt, 1.05% Li₂O base, Savannah Resources is positioning this Portuguese project to sit in the lower half of the cost curve among hard‑rock spodumene assets in our database, which could keep it viable through cyclical price troughs.
The 2018 World Heritage agricultural designation for the Barroso region means that securing environmental licensing by year‑end will likely require more intensive baseline, water, and land‑use studies than for comparable lithium projects in our coverage that are outside protected landscapes, potentially front‑loading ESG spend but de‑risking later legal challenges.
A forecast 1.5 Mt/y throughput starting around 2028 would make Barroso one of the larger European lithium projects in our database by plant scale, which is strategically significant for the European Union’s efforts to localise battery‑grade feedstock and reduce reliance on Australian and Canadian spodumene exports.
