Savannah’s Barroso Phase 1 DFS: mine design and scheduling notes for planners

30 Second Briefing
Savannah Resources has released the definitive feasibility study and maiden JORC Reserve for Phase 1 of the Barroso Lithium Project in northern Portugal, detailing a 14‑year open pit operation centred on 2.56 Mt of spodumene concentrate production. The DFS outlines conventional drill‑and‑blast mining with truck‑shovel haulage feeding a crush–grind–flotation plant, targeting battery‑grade spodumene for European converters. For geotechnical and mine planners, the phased pit development and long mine life provide a stable basis for slope design, waste scheduling and infrastructure staging.
Technical Brief
- Results explicitly cover only the initial 14‑year production window, leaving upside from later phases unmodelled.
Our Take
Our database shows relatively few Portugal‑based lithium items compared with Australian or Canadian projects, so Barroso’s 14‑year production window positions Savannah Resources as one of the more advanced EU‑hosted spodumene developers in current coverage.
The related Aldeia C‑190 piece from December 2025 indicates Savannah is consolidating additional lithium resources within the broader Barroso area, which could allow later phases to extend beyond the 14‑year period scoped in this Phase 1 DFS without major new jurisdictional exposure.
With 2.56 Mt of Phase 1 spodumene in Portugal, Savannah is one of the few lithium stories in our mining project pipeline where upstream supply is being advanced directly inside the EU, which likely strengthens its strategic appeal to European battery and auto OEMs seeking regional feedstock.
