    Arizona Gold’s Philadelphia project: underground vs open-pit lens for mine planners

    Arizona Gold’s Philadelphia project: underground vs open-pit lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Arizona Gold & Silver’s latest drilling at the Philadelphia project in Arizona has cut broad gold-silver mineralisation beneath the Red Hills target, including hole PC26-173 with 7 metres at 4.24 g/t gold and 15.2 g/t silver from 456 metres within 44 metres at 1.48 g/t gold and 7.2 g/t silver from about 446 metres. Hole PC26-172 returned 70 metres at 1.16 g/t gold and 5.6 g/t silver from 417 metres, including 10 metres at 3.27 g/t gold and 19.3 g/t silver from 459 metres, extending mineralisation down-dip in the Perry zone. The company is modelling a north-plunging higher-grade shoot within a 3‑km Arabian Fault corridor to evaluate both underground and bulk-tonnage open-pit scenarios.

    Technical Brief

    • Hole PC26-173’s broader 44 m interval includes 22 m at 2.52 g/t Au from 447 m.
    • The same hole also contains 13 m at 3.51 g/t Au from 456 m depth.
    • Philadelphia lies ~320 km northwest of Phoenix in the historic Oatman high-grade vein district.
    • Oatman district has historically produced >2.5 million oz Au from underground vein operations.
    • Arizona Gold & Silver has advanced Philadelphia since 2019, initially drilling from the property’s north end.
    • Acquisition of patented claims in 2021 enabled discovery of the Perry vein and associated stockwork zone.
    • Hole PC26-174 was drilled directly beneath PC26-173; assays are pending to constrain down-dip continuity.
    • Ongoing hole PC26-175 is collared ~60 m north of PC26-173 to test the revised high-grade shoot projection.
    • Drilling is also targeting a broad geophysical anomaly beneath Red Hills to link Perry Zone geometry and bulk-tonnage potential.
    • Market reaction was negative: AZS fell 13% to C$0.58, implying ~C$88 million market capitalisation.

    Our Take

    The combination of multi‑tens‑of‑metres gold intervals at depths beyond 400 m at the Philadelphia project and a modest Arizona Gold & Silver market cap of about C$88 million suggests that any move towards an initial resource could materially re-rate the company relative to other single‑asset juniors in our database.

    The 3 km Arabian Fault corridor at the Philadelphia property, in a district with historical production of 2.5 million oz of gold, implies scope for multiple shoot discoveries, which for practitioners means structural and vein continuity modelling will likely be as critical as simple step‑out drilling density in future programmes.

    Yancoal’s Kestrel acquisition: longwall geotechnical notes for mine planners

    Yancoal Australia has acquired an 80 per cent interest in the Kestrel underground metallurgical coal mine in Queensland’s Bowen Basin by purchasing 100 per cent of Kestrel Coal Group for an upfront US$1.85 billion cash consideration, subject to completion adjustments. The deal gives Yancoal control over a longwall operation producing premium hard coking coal linked to existing rail and port infrastructure at Gladstone. For geotechnical and mining teams, the acquisition signals continued investment in deep, high-capex underground coal with sustained demand for longwall support, strata control and ventilation expertise.

    Lynas–Meteoric deal and Caldeira project: strategic notes for mine planners

    Lynas Rare Earths will acquire Meteoric Resources in an all-scrip deal valuing Meteoric at about A$1.45 billion, securing the Caldeira ionic clay rare earths project in Minas Gerais, Brazil. Caldeira is described as the largest known ionic clay rare earth oxide resource outside China, with a definitive feasibility study due in the March 2026 quarter and first production targeted for 2028. The move gives Lynas a major non-Chinese, non-hard-rock feed source for its existing cracking and separation plants in Australia and Malaysia.

    Bubble–particle interaction in MAXGen cells: design notes for concentrator engineers

    TAKRAF Group is upgrading flotation performance with its DELKOR BQR MAXGen cells, using optimised hydrodynamics and improved bubble–particle interaction to boost recovery from increasingly complex ore bodies while cutting energy use. The MAXGen design focuses on controlled air dispersion, high shear zones and stable froth conditions to improve fine particle attachment and reduce reagent consumption. For brownfield concentrators, retrofitting these cells into existing circuits offers a relatively low-footprint route to higher metallurgical performance without major layout changes.
