    CleanTech Lithium expands Argentina foothold: project and capex notes for mine planners

    CleanTech Lithium expands Argentina foothold: project and capex notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    CleanTech Lithium has secured options over the Genoveva and Sal de Litio 1 brine properties in Argentina’s Salar de Antofalla, about 80 km from its Laguna Verde project in Chile, adjacent to Albemarle-held ground. The roughly $1.93 million deal, funded from existing cash, involves $525,000 in year-one payments and a further $1.4 million scheduled between October 2027 and May 2031, giving CleanTech the right to 100% ownership. Management is targeting a 2027 exploration start and is evaluating shared infrastructure and a centralised conversion facility in Copiapó across Laguna Verde, Viento Andino and Antofalla.

    Technical Brief

    • Option agreements cover 100% of the Genoveva and Sal de Litio 1 brine licences.
    • Antofalla tenements lie in Catamarca Province, contiguous with Albemarle-held exploration ground on the salar.
    • Transaction is fully funded from CleanTech Lithium’s existing cash, avoiding immediate equity or debt issuance.
    • Laguna Verde remains the lead development asset, with Antofalla positioned as a longer-term growth pipeline.
    • Management is assessing integration of Antofalla with Laguna Verde and Viento Andino for shared field infrastructure.
    • A single Copiapó conversion facility would centralise chemical processing, reducing duplicated plant capex across three projects.

    Our Take

    CleanTech Lithium’s move into Argentina around Salar de Antofalla effectively regionalises the Laguna Verde business case in Chile, where our coverage shows a pre‑tax NPV of $1.37 billion over 25 years, signalling a strategy to backstop that flagship with nearby brine optionality.

    With a London market value of about $25.5 million against a Laguna Verde PFS valuation in the billion‑dollar range, the 100% acquisition of Genoveva and Sal de Litio 1 looks geared to re‑rate the company as a multi‑basin lithium story rather than a single‑asset junior.

    The relatively modest scheduled follow‑on payments of $1.4 million between 2027 and 2031 suggest CleanTech Lithium is preserving balance‑sheet flexibility to fund process development and permitting at Laguna Verde while it de‑risks the new Antofalla and Viento Andino positions in Catamarca Province.

    SigraFi’s $35m ASGM facility: supply chain and risk notes for gold project teams

    SigraFi has secured a $35 million credit facility from a consortium led by UAE-based Ronin Commercial Brokers to finance gold offtake from organised artisanal and small-scale gold mining cooperatives in the DRC, Zambia and South America. The company already works with PeaceGold in eastern DRC, covering 11 cooperatives and about 25,000 miners in Ituri Province, using multi-year contracts and guaranteed offtake at competitive prices. The model targets ASGM’s roughly 20% share of global newly mined gold by providing traceable, compliant supply to institutional refiners previously reliant on informal channels.

    Tahmoor Colliery sale: restart staging and ground control checks for engineers

    Completion of the Tahmoor Colliery sale in New South Wales to the GEAR/M Resources Consortium moves the underground coking coal mine closer to full restart, with about 150 workers already back on site undertaking initial mining activities. The new operator plans a staged ramp-up, progressively recalling additional personnel and recommissioning equipment to restore longwall production. Geotechnical and operational teams will be focused on revalidating ground control, ventilation and gas management systems after the shutdown period before returning to full output.

    Avonbank mineral sands mining licence: design and tailings notes for engineers

    WIM Resource has secured a mining licence for the Avonbank mineral sands project in western Victoria, located about 15km north-east of Horsham, to extract a heavy mineral assemblage including zircon, titanium minerals and rare earth elements. The approval follows a formal assessment by Resources Victoria, clearing the way for large-scale dredge or dry mining of strandline-style deposits typical of the Murray Basin. For geotechnical and processing teams, the mix of zircon and rare earth-bearing minerals signals complex separation flowsheets and tailings management in fine-grained sands.
