    Hercules hires Hudbay deal team: Leviathan copper project lens for engineers

    First reported on MINING.com

    30 Second Briefing

    Hercules Metals has hired former Arizona Sonoran Copper CEO George Ogilvie and six ex-colleagues who led the Cactus project to a US$1.4 billion sale to Hudbay, tasking them with advancing the Leviathan porphyry copper discovery in Idaho. Leviathan’s system has been drilled over more than 1 km strike, up to 750 m width and 500 m vertical extent, with discovery hole HER-23-05 returning 185 m at 0.84% Cu including 45 m at 1.94% Cu, beneath an epithermal silver system. Barrick-backed Hercules controls 404.7 sq. km along a 73-km copper belt with surface mining rights, road access and three 260 kV transmission lines crossing the property, but no resource or economic study yet, giving the new team a blank technical slate.

    Technical Brief

    • Discovery hole HER-23-05 also reported 111 ppm Mo and 2.6 g/t Ag, ending in mineralisation.
    • Hercules estimates current drilling has tested only ~20% of the Leviathan porphyry target footprint.
    • Leviathan was identified in 2023 beneath an overlying epithermal silver system, implying stacked mineralisation styles.
    • Site lies near Cambridge, roughly two hours by road from Boise, simplifying future logistics and workforce access.
    • Surface tenure includes mining rights plus existing roads and three 260 kV transmission lines crossing the property.
    • Barrick-backed consolidation assembled 404.7 sq. km along a 73 km copper belt, enabling district-scale targeting.
    • Incoming team previously raised >US$300 million to advance the Cactus copper project before Hudbay’s acquisition.
    • Cactus’ 2025 resource totalled 1.04 Bt M&I at 0.48% Cu plus 211.7 Mt inferred at 0.37% Cu.
    • Hercules granted 18.65 million five-year options at C$0.59, equal to ~5.4% of current shares.
    • Management split assigns Paul to exploration drilling while Ogilvie’s group leads resource definition, studies, permitting and financing.

    Our Take

    The 16-fold value uplift achieved at Arizona Sonoran’s Cactus project, under the same executive group now at Hercules Metals, signals that Leviathan’s early drill profile and 73 km belt position are likely being framed for a similar ‘resource growth plus de-risking’ rerate path rather than a quick flip.

    Idaho copper projects are relatively under-represented in our copper- and silver-tagged coverage compared with Arizona, so Leviathan’s 404.7 sq km land consolidation along a defined belt could make Hercules one of the few regionally scaled copper names competing with Arizona-focused developers for US domestic supply narratives.

    Equinox appoints Orla’s Simpson as CEO: capex and integration lens for mine planners

    Equinox Gold will install Orla Mining’s Jason Simpson as CEO on 1 November, accelerating a leadership change just days after closing their C$25.4 billion all-share merger to form a six-mine producer targeting 1.1 million oz. of gold per year. The enlarged portfolio includes Greenstone, Valentine and Musselwhite in Canada, forecast to deliver 685,000 oz. annually, with further growth tied to South Railroad, Castle Mountain, Los Filos and an underground build at Camino Rojo. Simpson must quickly prioritise capex and integration as Greenstone and Valentine ramp up and Equinox prepares consolidated guidance.

    AECI Mining in Namibia: water stewardship design notes for mine planners

    Namibia’s expanding uranium, gold and copper sector is drawing new investment, and AECI Mining argues that project success will hinge on how efficiently operations manage scarce water and other natural resources. The company promotes integrated blasting, reagent and water-treatment packages tailored to arid conditions, linking emulsion explosives, process chemicals and closed-loop water circuits to cut freshwater intake and improve plant stability. For mine planners and process engineers, the message is to embed water stewardship into early pit design, tailings strategies and plant selection rather than bolt-on compliance later.

    Record gold output and record costs: key signals for mine planners

    Gold gave back Thursday’s post-Fed bounce, with the Comex continuous contract down 1.6% to $4,037.86/oz and December futures at $4,099.50/oz as traders priced a 63% chance of a September US rate hike. World Gold Council data show record mine output of 966 tonnes in Q2 and 1,867 tonnes in H1, but industry all-in sustaining costs hit a record $1,785/oz in Q1, driven by higher royalties and overheads, with further energy cost pressure emerging. Production growth was concentrated in Canada, Chile, Burkina Faso and Ghana, while Mexico, Nicaragua, the US and China declined, and central banks bought a net 289 tonnes in Q2, a record for a second quarter.
