    Antipa Minyari drilling campaign: design and pit shell notes for mine planners

    Antipa Minyari drilling campaign: design and pit shell notes for mine planners

    First reported on Australian Mining

    30 Second Briefing

    Antipa Minerals has started a major drilling campaign at its 100 per cent-owned Minyari gold-copper project in Western Australia’s Paterson Province, targeting resource growth and higher-grade zones around existing deposits. The programme focuses on step-out and infill drilling near current mineralisation, using reverse circulation and diamond core holes to refine geological models and upgrade JORC classifications. Geotechs and mine planners should watch for new intercepts that could materially change pit shell geometry, geotechnical domains and potential underground development options at Minyari.

    Technical Brief

    • Campaign is described as “major”, implying multi-rig, multi‑month drilling with substantial metreage commitment.
    • Work is entirely within Antipa’s 100 per cent-owned Minyari mining leases, simplifying approvals and data confidentiality.
    • Paterson Province setting suggests Proterozoic basement targets beneath variable cover, influencing drilling methods and casing strategy.
    • Gold–copper focus implies logging for both sulphide style and potential supergene enrichment, affecting sample intervals.
    • Reverse circulation and diamond drilling combination enables both rapid coverage and oriented core for structural modelling.
    • New data will feed directly into JORC resource updates, constraining slope design and underground access studies.
    • Paterson logistics (remote desert, seasonal heat) will drive water supply, rig access and sample transport planning.

    Our Take

    Our database shows a sequence of Minyari updates since late 2025 – including a standalone open‑pit resource (Dec 2025) and a resource upgrade (Apr 2026) – so this new drilling phase in the Paterson Province is likely aimed at tightening pre‑feasibility assumptions rather than early‑stage discovery work.

    With Minyari confirmed as a 100 per cent‑owned gold–copper–silver asset and pre‑feasibility work already underway (Dec 2025 PFS progress article), Antipa Minerals is positioning the project as a potential standalone development in Western Australia rather than relying on toll treatment or third‑party infrastructure.

    Kathleen Valley expansion: early works and procurement lessons for mine planners

    Early works and long‑lead procurement have started for Liontown Limited’s planned expansion of the Kathleen Valley Lithium Operation in Western Australia, ahead of a formal Final Investment Decision targeted for the end of Q1 FY2027. The programme covers critical items and packages whose fabrication and delivery times could otherwise delay ramp‑up of the underground mine and processing plant. Early commitment to these components signals a push to lock in key OEM capacity and manage schedule risk in a tight lithium project pipeline.

    Metals Australia’s $2.05B Baie‑Comeau graphite refinery: project and IRR lens for engineers

    Metals Australia plans a C$2.05 billion high‑purity graphite refinery near Baie‑Comeau, Quebec, designed to process 75,000 tonnes per year of flake graphite concentrate into 51,000 tonnes of battery‑grade products over a 25‑year life, with a projected 25.6% internal rate of return and 227 permanent jobs. Feedstock will come from its Fermont project averaging 10.2% graphite, about 2.4 times higher grade than publicly reported for Nouveau Monde Graphite, and the site leverages rail‑ferry links plus a deep‑water port. The company will bypass a traditional PFS, moving directly to final feasibility while running parallel community and Indigenous engagement to meet Canada’s 2040 graphite mine and refinery targets.

    Ur-Energy’s Shirley Basin uranium start-up: ISR project metrics for mine planners

    Ur-Energy has begun in situ recovery uranium production from Mine Unit 1 at its Shirley Basin project in Wyoming, capturing uranium-bearing solution following completion of wellfield installation, processing circuits and permitting. The project has licensed annual wellfield and toll-processing capacity of up to 2.0 million lb U₃O₈ equivalent, with 9.1 million lb U₃O₈ in Measured and Indicated resources at an average 0.22% eU₃O₈ and an anticipated nine-year mine life across three shallow units. Uranium is loaded onto ion exchange resin on site and is expected to be trucked to the Lost Creek plant for final processing, drying and packaging from this summer, pending a further regulatory inspection.
