    Aeris triples Golden Plateau resource: mine design and geotech notes for planners

    First reported on Australian Mining

    30 Second Briefing

    Aeris Resources has tripled contained metal at the Golden Plateau deposit in Queensland, reporting a 220 per cent increase to a mineral resource estimate of 3Mt at 2.1g/t gold and 8g/t silver. The resource sits within trucking distance of Aeris’ existing Cracow processing plant, directly supporting plans to extend mine life beyond the current reserve base. For mine planners and geotechs, the larger, moderate-grade inventory justifies further infill drilling, geotechnical characterisation and potential redesign of stoping sequences and backfill strategies.

    Technical Brief

    • Silver by-product at 8g/t offers minor revenue credit, influencing cut-off grade optimisation.
    • Increased inventory at a satellite deposit typically enables longer-term scheduling of pastefill or cemented rockfill demand.
    • Proximity to an operating mill reduces permitting complexity compared with a greenfield standalone processing facility.
    • Additional drilling to support the updated MRE will also refine geotechnical domains for stope design.
    • Similar satellite-to-central-plant models in Australian goldfields have reduced unit processing costs versus isolated small plants.

    Our Take

    Aeris Resources has recently been portrayed in our database as copper‑centric, with multiple 2026 items on Tritton and the Peel Mining acquisition, so the Golden Plateau gold and silver inventory at Cracow slightly rebalances its portfolio back towards precious metals exposure.

    The 2.1 g/t gold and 8 g/t silver grades at Golden Plateau sit in the mid‑range of underground gold grades in our Mining–Projects coverage, which suggests that project value will hinge more on tonnage, continuity and existing Cracow infrastructure than on exceptionally high grade alone.

    In our coverage of Aeris’ Tritton ore reserve expansion and South Cobar additions, the company has consistently used resource growth to extend mill life and smooth production profiles, implying that the Golden Plateau uplift is likely being targeted at sustaining or backfilling Cracow plant throughput rather than a standalone development push.

    Forrestania–Zenith takeover cleared: portfolio and drilling impacts for mine planners

    Forrestania Resources has declared its off‑market takeover offer for Zenith Minerals unconditional after securing a 58.99 per cent relevant interest, waiving all remaining defeating conditions and satisfying its minimum acceptance threshold. The move consolidates control over Zenith’s lithium, gold and base metals portfolio in Western Australia and Queensland, including the Split Rocks and Waratah Well projects. For geologists and mine planners, the deal signals likely rationalisation of exploration budgets, potential re‑prioritisation of drilling targets, and scope for integrated resource modelling across the combined tenement package.

    Motion–Atmus diesel filtration case study: reliability lessons for mine fleets

    Motion and Atmus are deploying Fleetguard bulk diesel filtration and heavy-duty coolant solutions to protect mine fleets from fuel-borne contaminants before fuel reaches engines. By filtering diesel at bulk storage tanks, transfer pumps and dispensing points, the system targets water, particulates and microbial growth that typically cause injector wear, pump failures and unplanned downtime in high-load haul trucks and excavators. For maintenance teams, the approach shifts focus to upstream fuel conditioning, potentially extending service intervals and stabilising availability of critical diesel assets.

    AIC Mines’ record $33m Eloise cash flow: throughput and capex signals for engineers

    AIC Mines has reported record quarterly net mine cash flow of $33.4 million from the Eloise underground copper operation in Queensland, after investing $7.9 million in capital during the September 2026 quarter. The result was driven by higher copper sales and coincides with commissioning of an expanded processing plant that has started ahead of schedule. For engineers, the key signals are stronger project cash generation to support further mine development and the imminent step-up in concentrator throughput once the upgraded plant is fully online.
