Sedgman wins Barroso lithium FEED: design and risk notes for project engineers

30 Second Briefing
Sedgman has secured the Front-End Engineering and Design contract for the lithium concentrator plant at Savannah Resources’ Barroso lithium project in northern Portugal, following its earlier work on the process flowsheet and Definitive Feasibility Study plant design. The FEED scope will refine equipment selection, layout and mass–energy balances for the hard-rock spodumene concentrator, de-risking capital estimates ahead of a final investment decision. For geotechnical and civil teams, the move signals progression towards detailed earthworks, foundations and tailings/waste infrastructure design on what is billed as mainland Europe’s largest lithium project.
Technical Brief
- Sedgman’s scope follows its earlier process flowsheet development, enabling continuity of design assumptions into FEED.
- FEED phase will lock in plant layout decisions that drive earthworks volumes and foundation footprints.
- Early definition of major equipment packages will influence structural steel tonnage and building envelope sizing.
- Integration of Sedgman’s DFS plant design into FEED reduces rework risk at detailed design and EPC stages.
- Concentrator FEED outcomes will set boundary conditions for subsequent tailings and waste facility engineering.
Our Take
Sedgman’s FEED role at Barroso follows its work on the North American Lithium expansion in Québec, suggesting Savannah Resources is tapping a contractor with recent, directly comparable spodumene concentrator experience in advanced jurisdictions.
Our database shows multiple recent Savannah Resources items on Barroso, including the definitive feasibility study and early equipment orders, so awarding FEED now signals the project is moving from study-led optimisation into a more execution-ready phase in Portugal.
The benefit sharing agreements Savannah has already signed with local baldios in the Barroso region indicate that progressing to FEED on the lithium concentrator plant is underpinned by a relatively advanced land access and social licence framework compared with many European greenfield projects.
