    Harena eyes California rare earth, uranium assets: geology and drilling lens for mine planners

    Harena eyes California rare earth, uranium assets: geology and drilling lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Harena Rare Earths has entered an exclusivity agreement to acquire Paradigm Critical Minerals’ heavy rare earth and uranium exploration portfolio in San Bernardino County, California, near MP Materials’ Mountain Pass mine, the only operating rare earth mine in North America. Historical work on the former gold-silver operation reports rare earth samples up to 2% TREO with elevated heavy rare earths, plus uranium intercepts of 30.3 m at 0.37% U₃O₈e and internal zones up to 10% U₃O₈e. Harena plans modern mapping, trenching, geophysics and drilling following due diligence.

    Technical Brief

    • Exclusivity agreement grants Harena sole negotiation rights while it completes technical, legal and commercial due diligence.
    • Assets sit in San Bernardino County, the California jurisdiction with the highest number of mines and claims.
    • Paradigm Critical Minerals is the current owner of the heavy rare earth and uranium permit portfolio.
    • Historical work evolved from gold–silver mining to uranium drilling, with rare earths only recently recognised.
    • Harena draws geological analogies to Bancroft (Canada), Midnite (US), and Rössing/Husab (Namibia) uranium districts.
    • Company intends a modern systematic programme: detailed mapping, channel sampling, trenching, geophysics and follow-up drilling.
    • Harena’s existing Ampasindava project in Madagascar hosts 699 Mt at 868 ppm TREO (606,000 t TREO contained).

    Our Take

    With 699 Mt at 868 ppm TREO at Ampasindava, Harena Rare Earths is moving into the same scale bracket as the larger ionic clay stories in our Mining coverage, which typically aim at long-life, low-strip operations rather than high-grade, small-footprint plays.

    Historical uranium intercepts up to 10% U₃O₈e in the portfolio suggest that any California or North American uranium oxide targets could be positioned as higher-grade, drill-defined prospects, which in our database tend to attract more interest from utilities and traders once permitting pathways are clearer in the United States.

    The presence of MP Materials’ Mountain Pass mine alongside uranium assets in San Bernardino County places Harena’s M&A focus squarely in one of the few US regions where rare earth and uranium permitting, infrastructure and technical expertise already overlap, which can shorten lead times compared with greenfield critical minerals projects elsewhere in North America.

    Endurance Gold Reliance step-outs: resource and metallurgy lens for mine planners

    Endurance Gold’s 2026 drilling at the Reliance project in southern British Columbia has returned high-grade step-outs outside the current resource, including 14.7 metres at 7.67 g/t gold and 0.13% antimony from 75.9 metres in DDH26-128 and 12 metres at 3.07 g/t gold from 98.2 metres in DDH26-129, a 60-metre step-out along the Eagle trend. The 8,000-metre diamond programme, with seven holes (1,899 metres) already completed at southern Eagle and two deep tests at Imperial, targets conversion of near-surface ounces and deeper Royal Shear extensions. Reliance currently hosts 19.6 million inferred tonnes at 2.3 g/t gold (1.45 million oz), with metallurgical work aiming to improve recoveries beyond earlier 84.7% gold to concentrate.

    Caterpillar 794 AC at Quellaveco 500 Mt milestone: haul design notes for engineers

    Caterpillar’s autonomous 794 AC haul truck fleet at Anglo American’s Quellaveco copper mine in Moquegua, Peru has passed 500 Mt of material moved, with Ferreyros supporting the deployment as Caterpillar’s local representative. The fully autonomous trucks operate on steep, high-altitude pit ramps typical of Andean copper operations, integrating with digital fleet management and high-precision guidance systems. The milestone signals growing confidence in large-scale autonomous haulage for greenfield copper projects, with implications for haul road design, traffic management rules, and maintenance planning.

    Los Bronces–Andina JV: integrated mine plan implications for planners and geotechs

    Anglo American, via its 50.1%-owned Anglo American Sur SA, and Codelco have finalised a definitive agreement to run a joint mine plan for the adjacent Los Bronces and Andina copper operations in central Chile, after securing all competition and regulatory approvals. The integrated planning covers two large-scale open pits sharing the same Andean district, enabling coordinated sequencing of ore bodies, waste dumps and tailings storage across property boundaries. For mine planners and geotechnical teams, this opens scope for shared slope design, haul road rationalisation and potentially consolidated infrastructure for high-altitude water and power supply.
