    Ausgold Katanning high-grade drilling: pit design and throughput notes for engineers

    Ausgold Katanning high-grade drilling: pit design and throughput notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Ausgold has reported a new wave of high-grade reverse circulation and diamond drilling results at its Katanning gold project (KGP) in Western Australia, pointing to potential resource growth beyond the current central zone. Intercepts from the Jinkas South and Dingo areas extend known mineralisation along strike and at depth, with multiple thick zones of +2g/t Au reported close to surface. The results support further infill and step-out drilling in 2025, with implications for expanding open-pit designs and optimising future processing plant throughput at Katanning.

    Technical Brief

    • Reverse circulation and diamond drilling targeted Jinkas South and Dingo satellite zones outside the current central resource.
    • Several intercepts show continuous mineralised zones suitable for potential bulk-tonnage open-pit geometries.
    • Drill spacing in new areas is being tightened to support conversion from Inferred to Indicated resources.
    • Step-out drilling is progressively extending mineralised envelopes along strike, informing future pit shell optimisation.
    • Down-dip extensions intersected by diamond holes provide structural data to refine 3D geological and grade models.
    • New results will feed into updated pit designs, influencing waste:ore strip ratios and haulage profiles.
    • Ausgold is sequencing further drilling to align with planned feasibility-level mine planning and plant design work.

    Our Take

    Gold projects in Western Australia appear frequently in our 380 gold‑keyword pieces, suggesting Katanning will be competing for capital and skilled labour against a crowded pipeline of regional developments rather than standing out as an outlier.

    With 1205 Mining stories and over 2200 project‑tagged items, our coverage shows that Australian gold projects like Ausgold’s Katanning increasingly need clear scale or grade advantages to differentiate themselves in financing and offtake discussions.

    The Western Australian setting for the Katanning gold project means Ausgold can likely leverage the state’s mature METS ecosystem highlighted in recent Australian Mining coverage, including local suppliers of crushing components and haulage technology that can shorten ramp‑up timelines and reduce logistics risk.

    Minnova’s C$76M PL gold mine restart: economics and strip risks for engineers

    Minnova plans a C$76.2 million restart of the brownfield PL gold mine near Sherridon, Manitoba, targeting 62,200 oz per year over 10 years from a high‑grade open pit feeding an existing 1,000 t/d plant, which is slated to double to 2,000 t/d in year two. The September resource stands at 3.76 million measured and indicated tonnes at 4.98 g/t Au (601,158 oz) plus 1.67 million inferred tonnes at 3.78 g/t (202,810 oz), with open pits carrying a high 21:1 waste‑to‑ore strip ratio. At US$3,000/oz gold, the PEA projects an after‑tax NPV5 of US$180.6 million, 111% IRR, eight‑month payback and all‑in sustaining costs of US$2,288/oz, but value falls sharply at lower prices, underlining cost and strip sensitivity.

    Caterpillar Resource Industries leadership shift: fleet and autonomy cues for miners

    Caterpillar has confirmed that Denise Johnson, Group President of Resource Industries since 2016 and a key figure in expanding autonomous haulage and large mining truck platforms, will retire on 1 February 2027. Derrick York, currently President of Solar Turbines and a Caterpillar Senior Vice President overseeing industrial gas turbines and compressor sets, will become Group President of Resource Industries on 1 November 2026, with Johnson shifting to an advisory role. The handover timetable gives miners nearly a year of overlap to align major fleet, autonomy and support contracts with the incoming leadership.

    Anglo American copper scarcity and tech tie-ups: key takeaways for mine planners

    Tech companies are in talks to buy equity in Anglo American to secure long-term copper and other data centre metals, as Comex copper trades near $6.52/lb and LME cash copper recently hit a record $14,822/t. Anglo’s planned merger with Teck Resources would create a roughly $90 billion group producing about 1.2 million tonnes of copper per year, controlling around 5% of global supply, but is still awaiting Chinese antitrust clearance tied to concentrate flows to local smelters. Wanblad also warned Anglo may close its Brazilian nickel operations at Codemin and Barro Alto if the EU blocks the $500 million sale to MMG despite proposed long-term European ferronickel supply commitments.
