    Lithium Argentina hits guidance: expansion and DLE implications for mine planners

    Lithium Argentina hits guidance: expansion and DLE implications for mine planners

    First reported on MINING.com

    30 Second Briefing

    Lithium Argentina’s Cauchari-Olaroz brine operation in Jujuy hit 2025 guidance with about 34,100 tonnes of lithium carbonate, running at 97% of nameplate in Q4 and cutting cash operating costs below $6,000/t, down from $6,285/t in Q3. The $1 billion first-stage JV with Ganfeng (47%), Lithium Argentina (45%) and JEMSE (8.5%) is seeking environmental and RIGI approvals to add 45,000 t/y capacity and is evaluating direct lithium extraction to boost recoveries and reduce water use. A separate PPG salar project in Salta targets 50,000 t/y in phase one with about $1.1 billion initial capex.

    Technical Brief

    • First-stage Cauchari-Olaroz JV ownership split: Ganfeng 47%, Lithium Argentina 45%, JEMSE 8.5%.
    • Commercial production only commenced in 2024, so current performance reflects an early ramp-up year.
    • Q4 cash operating costs fell from $6,285/t in Q3 to below $6,000/t LCE sold.
    • Q4 net debt reduction of $26 million achieved while distributing $15 million to each JV partner.
    • JV submitted both an environmental permit and RIGI large-investment financing application for the Cauchari-Olaroz expansion.

    Our Take

    Running Caucharí-Olaroz at 97% of nameplate while still carrying over US$150 million in liquidity and cutting net debt by US$26 million in Q4 suggests Lithium Argentina can credibly advance the US$1.1‑billion first phase at Pozuelos‑Pastos Grandes without relying solely on equity markets, which is notable given current lithium price pressure across our coverage.

    The ownership split at Caucharí‑Olaroz (45% Lithium Argentina, 47% Ganfeng, 8.5% JEMSE) gives the Jujuy provincial vehicle a meaningful minority stake, which in our database has tended to smooth permitting and social licence for brine projects in Argentina’s portion of the lithium triangle compared with greenfield plays without provincial equity.

    Within our 53 lithium‑keyword pieces, few operators in northwestern Argentina report this level of capacity utilisation so early in ramp‑up, which likely strengthens Lithium Argentina’s case when seeking Argentine government‑linked financing versus peers still struggling with evaporation pond performance or reagent optimisation.

    Scope Systems cyber attack: resilience and risk lessons for mining IT teams

    A ransomware attack on Perth-based Scope Systems’ Pronto Xi ERP cloud stack disrupted dozens of mining customers, including Northern Star Resources and Evolution Mining, in what MM‑ISAC’s Rob Labbe calls the broadest single third‑party cyber event the sector has seen. Scope says client servers were restored from backups and not directly accessed, but admits internal data was exfiltrated and has not disclosed the attack vector, raising questions about visibility at hypervisor, storage and backup layers. The incident spotlights how multi‑tenant vCenter/ESXi environments, VM cloning and snapshot abuse—already used by groups like Akira—could expose integrated exploration, production and maintenance data across more than 400 Pronto Xi‑reliant mining operations.

    Newmont’s Red Chris underground expansion: block cave design and capex notes for engineers

    Newmont’s Red Chris mine in British Columbia has secured an amended Environmental Assessment Certificate and Mines Act permit, allowing a shift from open-pit to underground block caving and extending operations into the mid-2040s. The copper-gold porphyry deposit in the Golden Triangle hosts an estimated 20 million oz of gold and 13 billion lb of copper, with the block cave expected to lift Canada’s copper output by about 15%. The project entails several billion dollars in capital, around 1,800 construction jobs and roughly 1,500 operating roles at peak.

    Goldman cuts gold price forecast to US$4,900: planning notes for mine projects

    Goldman Sachs has cut its end‑2026 gold price forecast by US$500/oz to US$4,900/oz after the US Federal Reserve, under new chair Kevin Warsh, signalled a hawkish shift that has pushed market-implied December rate hike odds to 87%. Spot gold has already fallen to about US$4,100/oz, down 27% from its near‑US$5,600/oz January peak, with three consecutive monthly losses between March and May and a 4% year‑to‑date decline. Goldman warns a 2026 year‑end target as low as US$4,400/oz is possible if rates rise, partly offset by ongoing central‑bank buying of roughly 50 tonnes/month this year and 40 tonnes/month next year.
