Red Hill Broken Hill drilling campaign: targeting geometry and grade for mine planners

30 Second Briefing
Red Hill Minerals has started a 1700m, two-hole diamond drilling program at its 860km² Broken Hill project in New South Wales, targeting the Furiosa copper–gold system and the Dementus lead–zinc–silver lode within the Curnamona joint venture. The campaign includes a 700m diamond hole into the previously untested Furiosa target, designed to intersect a modelled conductive body interpreted from geophysics. Results will clarify the geometry and grade potential of both mineral systems, guiding follow-up drilling and resource definition in a district already known for high-grade Broken Hill–type deposits.
Technical Brief
- Core orientation and downhole surveys expected to refine 3D geometry of both mineralised systems.
- Programme design leverages earlier surface geophysics, with drilling aimed at validating conductive and chargeable anomalies.
- Broken Hill district context implies potential for structurally thickened, high-grade lodes requiring precise structural interpretation.
- Results will determine whether follow-up step-out drilling targets down-plunge extensions or parallel shoots.
- Early-stage campaign keeps capital exposure relatively low while testing two discrete polymetallic targets.
- Outcomes will influence JV budgeting, including potential escalation to multi-rig resource definition drilling.
Our Take
Red Hill Minerals is simultaneously advancing copper–gold drilling at its Anabama project in South Australia, signalling a multi-asset exploration push that could allow capital and technical teams to be shared across Broken Hill and Anabama if either delivers a discovery.
In our database of 1264 Mining stories, Broken Hill and New South Wales feature less frequently for copper–gold than Western Australian greenfields, so a sizeable 860km² project here positions Red Hill as a relatively early mover in reviving polymetallic exploration around the historic camp.
The modest two-hole, 1700m diamond programme at the Broken Hill project mirrors the 1200m, two-hole EM‑targeted campaign at Anabama, suggesting Red Hill is using tightly scoped, geophysics-led drilling to de-risk targets before committing to larger metreage or more complex JV funding on the Curnamona ground.
