    AIC Mines’ Eloise and Jericho copper reserves: mine design and scheduling notes

    AIC Mines’ Eloise and Jericho copper reserves: mine design and scheduling notes

    First reported on Australian Mining

    30 Second Briefing

    AIC Mines has reported record copper ore reserves at its Eloise and Jericho projects in Queensland, following an updated mineral resource and reserve estimate that extends mine life and supports higher long-term throughput at the Eloise processing plant. The combined underground operations, which target structurally controlled, high-grade sulphide lodes, are being optimised around existing decline access and ventilation infrastructure to reduce unit costs and improve stope sequencing. Geotechnical and mine planning teams will need to reassess ground support, paste fill requirements and scheduling to align with the larger reserve base and extended production horizon.

    Technical Brief

    • Mineralisation remains dominated by high-grade sulphide lodes associated with shear zones and structural complexity.
    • Eloise’s existing processing plant configuration is retained, avoiding major new surface plant capital.
    • Decline access and established ventilation circuits at both mines constrain stope layout and expansion directions.
    • Integration of Jericho ore into Eloise’s plant feed requires careful blending to manage variable sulphide textures.
    • Paste fill demand will increase in secondary stopes as extraction fronts extend along strike and at depth.
    • Longer mine life will necessitate staged refurbishment of underground services: power reticulation, pumping and ventilation.
    • Similar brownfield copper operations with multiple lodes can apply comparable optimisation around existing declines and fans.

    Our Take

    The all-time-high copper reserves at Eloise and Jericho are consistent with AIC Mines’ recent report of materially expanded high-grade mineralisation at depth at Jericho (Dec 2025), suggesting the resource base is still in a growth phase rather than approaching maturity.

    Underground connectivity between Eloise and Jericho, confirmed in the February 2026 item, means higher reserves can likely be scheduled through a shared infrastructure corridor, which typically lowers unit costs and de-risks development of the satellite orebody in north-west Queensland.

    Within our Mining projects coverage, copper items linked to Australian underground operations like Eloise–Jericho are relatively prominent among the 1815 copper keyword-matched pieces, signalling that brownfield reserve growth in established camps is a key theme for Australian copper supply rather than greenfield builds.

    Top 50 mining companies add $250bn in 2026: capital and project signals for engineers

    Global mining majors added $250 billion in value in early 2026, lifting the MINING.COM Top 50 to a combined $2.41 trillion despite the US–Iran war and volatile gold at about $4,700/oz and silver above $70/oz, both off record spikes. BHP briefly exceeded a $200 billion market capitalisation, copper contributed $7.95 billion to its half‑year operating earnings, and six miners – including Agnico Eagle, Zijin Mining, Southern Copper and Newmont – now sit in the $100‑billion club. At the other end, Amman Minerals fell 27% on Indonesian smelter delays and Ivanhoe Mines cut Kamoa‑Kakula 2026 copper guidance to 290,000–330,000 tonnes, dropping it below the $18 billion Top 50 cut‑off.

    pH7 Technologies’ closed-loop PGM and chalcopyrite leaching: key notes for mine planners

    Canadian processor pH7 Technologies is expanding its Vancouver facility, backed by up to C$4 million from NRC IRAP, to scale its organo-electrochemical platform that recovers platinum, palladium and rhodium from secondary materials without toxic reagents or tailings wastewater. The commercial plant already processes spent catalytic converters, producing 30,000–40,000 oz of platinum-equivalent PGMs per year under a tolling and offtake model involving partners such as Mitsubishi. pH7 is now piloting electrochemically generated oxidants to heap leach chalcopyrite and other sulphide ores without cyanide, targeting on-site mine deployment within 1–2 years across South America, Africa and Australia.

    Dellner Bubenzer mining brakes: integrated drivetrain design notes for engineers

    Dellner Bubenzer is supplying a wide range of industrial brakes and couplings for mining hoists, slewing drives and belt conveyors, developed in long-term collaboration with OEMs. The company focuses on both service and emergency braking solutions tailored to heavy-duty mining duty cycles and harsh environments, addressing controlled hoisting, precise slewing and high-tension conveyor stopping. For engineers, the key point is an integrated approach to drivetrain and braking design, rather than bolt-on safety systems, across multiple critical mining applications.
