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

    July 23, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    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.

    Glencore’s US$250m Cat order for Alumbrera: fleet renewal lens for mine planners

    Glencore has placed a US$250 million order with Finning’s South America business to supply more than 20 large Caterpillar mining trucks, ancillary equipment and technology support for the planned 2026 restart of the Alumbrera copper mine in Argentina. The package, disclosed in Finning’s Q1 2026 results, centres on fleet renewal and digital support rather than life-extension of legacy units. For mine planners and maintenance teams, the scale and timing signal a shift towards a modernised, OEM-supported truck fleet ahead of full production ramp-up.

    MAX Power’s Lawson hydrogen project expansion: scale and infrastructure lens for engineers

    MAX Power Mining has secured an additional 155,125 acres (628 sq. km) of permits contiguous with its 1,224 sq. km Lawson natural hydrogen project in south-central Saskatchewan, creating the newly named Aurora project on a basement-controlled structural play along the Paleoproterozoic–Archean contact of the Sask Craton. The company has now accumulated 660,263 acres (2,672 sq. km) of provincial permits across the Genesis Trend while running a multi-well commercial validation drill programme at Lawson targeting large-scale natural hydrogen. An MOU with the City of Moose Jaw links potential hydrogen development to a nearby heavy industrial and major data centre corridor, signalling early focus on local offtake and infrastructure integration.

    American Mineral Resources’ diversified portfolio: capex and jurisdiction risk lens

    American Mineral Resources is assembling a seven-jurisdiction portfolio across Quebec, British Columbia, Yukon, Chile, New Zealand, Western Australia and Tanzania, with its Piscau North polymetallic project in Quebec earmarked for a separate Canadian Securities Exchange listing, as it targets a Nasdaq uplist within 12 months via the OTCQB. CEO Ryan Cunningham is prioritising projects with existing permits or modest capex and argues that jurisdictional risk now rivals grade, citing Quebec’s Gaspé oil drilling ban as a warning. He also points to Canada’s flow-through share regime as a key financing advantage over US markets still fixated on AI and tech.
