    Dreadnought RC drilling at Illaara: design, cost and pit-shell notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Dreadnought Resources has started reverse circulation drilling at the Metzke’s Find prospect within its 100 per cent owned Illaara gold project in Western Australia, targeting structurally controlled high-grade gold along a previously defined shear corridor. The RC programme is designed to step out from earlier intercepts and test down-dip and along-strike extensions of mineralisation, using relatively low-cost, high-production hammer drilling suited to the hard Archaean greenstone host rocks. Results will guide follow-up diamond drilling, resource definition and potential pit shell optimisation across the broader Illaara trend.

    Technical Brief

    • RC programme at Metzke’s Find is configured for rapid metreage through hard Archaean greenstones.
    • Hammer drilling is being used specifically to maintain penetration rates and sample quality in competent rock.
    • Step-out holes are planned both along strike and down dip from prior intercepts to define continuity.
    • RC chips will provide preliminary lithological and alteration logging ahead of any oriented diamond core work.
    • Sampling strategy is geared to generate assay data suitable for early-stage pit shell and optimisation studies.
    • Results are expected to refine structural models controlling mineralisation ahead of detailed resource drilling design.

    Our Take

    Western Australian gold projects like Dreadnought Resources’ Illaara and Ora Banda Mining’s Little Gem and Round Dam (covered on 11 March 2026) are clustering exploration around existing processing hubs, which can materially lower future capex if toll treatment or plant-sharing options are pursued.

    Gold is one of the most densely covered commodities in our Mining database, and new drilling at prospects such as Metzke’s Find tends to be scrutinised for shallow, high-grade hits that can be fast-tracked into small-scale open pits to feed underutilised mills in the region.

    For junior explorers in Australia, early RC drilling success at projects like Illaara often underpins the next round of equity raisings, so assay results here are likely to influence Dreadnought Resources’ near-term funding and joint-venture negotiation leverage.

    From reactive to predictive mining safety: data and sensing priorities for engineers

    Mining safety specialist David Coghlan, head of technology and product at TURCK, argues that connected sensing and control must shift mines from reactive alarms to predictive intervention as fleets, conveyors and fixed plant become more automated. He points to integrated proximity detection, real-time location and condition monitoring on mobile equipment, tied into site-wide networks, as the basis for predicting collision and entrapment risks rather than just logging incidents. For geotechnical and operations teams, this means designing safety systems around data quality, latency and interoperability, not just compliance with existing guarding and lock-out procedures.

    Evolution becomes Carnaby’s largest shareholder: M&A and project signals for mine planners

    Evolution Mining has become Carnaby Resources’ largest shareholder with a 13.7 per cent stake after acquiring the QIC Queensland Critical Minerals Fund’s ~37.9 million Carnaby shares as part of its proposed $213 million takeover. Evolution also issued about 2.6 million new shares to QIC, signalling continued use of scrip-based structures in Australian mid-tier M&A. For copper–gold project developers, the move points to stronger strategic interest from established producers in advanced exploration portfolios rather than greenfield assets.

    Develop’s Woodlawn drilling: 15-year mine life implications for planners and geotechs

    Develop Global’s latest underground drilling at the Woodlawn copper–zinc mine in New South Wales has returned intercepts grading up to 15.7 per cent copper equivalent (CuEq), supporting its Project DM15 plan to extend mine life from 10 to 15 years. The high-grade results, from step-out holes targeting depth extensions of existing lenses, suggest additional sulphide resources beyond the current reserve envelope. For mine planners and geotechs, this points to a longer stoping schedule, potential redesign of sequencing and backfill, and extended use of existing underground infrastructure.
