    Chilean Assets Deliver High-Grade Copper and Gold Results

    Lodestar Minerals (ASX: LSR) has unveiled an impressive investor presentation highlighting its strategic position in Chile's renowned Iron Oxide-Copper-Gold (IOCG) and Porphyry Copper Deposit (PCD) belt. The company's Darwin and Three Saints Projects have returned exceptional surface sampling results, with gold grades reaching as high as 247 g/t Au and copper values up to 8.09% Cu.

    Recent reverse circulation (RC) drilling has intersected promising mineralisation, with over 60% of assay results still pending. Initial findings confirm the presence of alteration minerals indicative of potential IOCG and porphyry-type deposits, as well as high-grade gold veins.

    "The presence of alteration minerals linked to PCDs and IOCG-type mineralisation is highly encouraging for the prospectivity of the ground," stated Coraline Blaud, Head of Exploration and Non-Executive Director.

    Strategic Location Offers Significant Advantages

    Lodestar's Chilean projects benefit from exceptional infrastructure and proximity to established mining operations:

    Infrastructure Advantage Details
    Road Access Sealed access road crossing the tenement
    Power 20km from highway with high voltage electricity
    Mining Hub 75km southwest of CopiapĂ³, Chile's main mining district
    Port Access 30km to the sea, 90km from industrial port of Huasco
    Year-round Operations Low altitude range allows access throughout the year

    The projects are strategically positioned within 70-120km of major mines including:

    • Candelaria Mine (IOCG): 1.4Mt @ 0.56% Cu, 0.12 g/t Au & 1.9 g/t Ag
    • Dos Amigos & Tricolor mines (PCDs): 320Mt @ 0.36% Cu and 0.26 g/t Au

    Understanding IOCG Deposits: Chile's Mineral Powerhouse

    Iron Oxide-Copper-Gold (IOCG) deposits represent one of the most valuable deposit types in mining. Unlike porphyry deposits, IOCGs can contain significantly higher gold grades alongside copper, making them particularly attractive targets.

    Chile's Coastal Cordillera hosts numerous world-class IOCG deposits formed along the Atacama Fault System. These deposits typically feature:

    • Strong structural control along major fault systems
    • Extensive alteration halos including iron oxides, potassic, and sodic alteration
    • Polymetallic mineralisation (Cu, Au, Fe, and sometimes U, REE)
    • Variable depths from near-surface to several hundred metres

    For investors, IOCG deposits offer compelling economics due to their potential for higher-grade zones, multiple valuable commodities, and often favourable metallurgy.

    What are IOCG Deposits?

    IOCG (Iron Oxide-Copper-Gold) deposits are a distinct class of mineral deposits characterised by their association with iron oxides (magnetite and hematite) and significant copper and gold content. These deposits formed through hydrothermal processes, where mineral-rich fluids moved through rock fractures and deposited valuable minerals.

    Key characteristics of IOCG deposits include:

    1. Mineral Composition: Primary economic minerals include copper sulphides (chalcopyrite, bornite) and gold, with iron oxides (magnetite, hematite) as the dominant non-economic minerals.

    2. Geophysical Signatures: Strong magnetic and/or gravity anomalies due to the presence of dense iron oxides, making them detectable through geophysical surveys.

    3. Size and Grade: Typically large tonnage (100-1000+ million tonnes) with moderate to high grades (0.5-1.5% Cu and 0.2-1.5 g/t Au).

    4. Structural Control: Formation along major fault systems that serve as conduits for mineralising fluids.

    Chile hosts several world-class IOCG deposits, with the Candelaria mine being a prime example. These deposits contribute significantly to the country's status as the world's largest copper producer.

    Accelerated Exploration Timeline Underway

    Lodestar has outlined an aggressive exploration schedule for the coming months:

    Timeline Planned Activities
    June 2025 • Completion of drone-based magnetometry survey
    • Reconnaissance field visit
    • Re-assay of quartz veins encountered during RC drilling
    July 2025 • Comprehensive soil sampling program across newly defined targets
    August-September 2025 • Second round of targeted drilling

    The company has identified multiple high-priority targets based on:

    • Historical workings extending up to 1.8km in strike length
    • Mineralised trends extending under cover into Lodestar's tenements
    • Large untested magnetic anomalies identified under cover
    • Numerous structures branching from the main Atacama Fault system

    Diversified Project Portfolio Reduces Risk

    While the Chilean assets represent Lodestar's primary focus, the company maintains a balanced portfolio of Australian projects:

    Earaheedy Project (Copper & Gold)

    • 800 square kilometre land package in the emerging Earaheedy Basin
    • Volcanogenic Massive Sulphide (VMS) style potential in the same geological age as the DeGrussa copper deposit
    • Historical drilling at Main Gossan intersected 2m at 4.65% Cu and 3m at 1.97% Cu
    • Recent soil sampling identified three new target areas requiring follow-up

    Ned's Creek Project (Gold)

    • Multiple gold prospects with previous exploration returning grades up to 11m @ 29 g/t Au including 1m @ 151 g/t Au at Contessa
    • Located just 40km from the Plutonic Gold Mine and Processing Plant (5.5M oz historical production)
    • Mineralisation concentrated along granite intrusive contact

    Strategic Lithium Exposure

    • Holds 27.5M performance rights in Future Battery Minerals' Coolgardie Lithium Project
    • Rights convertible upon proving a mineral resource of >10Mt @ 1.0% Liâ‚‚O
