    Alkane’s deeper gold at Peak Hill: geotechnical and mine planning takeaways

    Alkane’s deeper gold at Peak Hill: geotechnical and mine planning takeaways

    First reported on Australian Mining

    30 Second Briefing

    Alkane Resources has intersected gold–copper mineralisation about 1km below the former Proprietary open pit at Peak Hill, NSW, in 1651m diamond hole PHD084, which cut altered zones with low-grade mineralisation interpreted as a continuation of the Peak Hill epithermal system. The company is weighing a follow-up deep drilling campaign targeting this down-plunge potential beneath the historic open pit. For geotechnical and mine planners, any future underground concept will hinge on rock mass conditions at >1km depth and interaction with the existing pit wall and backfill.

    Technical Brief

    • Downhole geology shows broad alteration halos, suggesting a large fluid pathway rather than isolated pods.
    • Epithermal system continuity at depth raises potential for porphyry-style roots with different rock mass behaviour.
    • Any future underground access would need to negotiate legacy pit walls, ramps and possible backfill voids.
    • Historic open pit disturbance likely complicates crown pillar design and long-term pit slope stability.
    • Core from >1km depth offers new inputs for geotechnical domains, RMR/Q classification and seismic hazard assessment.

    Our Take

    Alkane Resources has been a frequent name in our Mining coverage, with other 2026 pieces showing it advancing gold, copper and rare earths prospects and posting record quarterly profit, which suggests the company has balance-sheet capacity to follow up deep drilling at Peak Hill if results justify it.

    The 1 km‑deep gold–copper intercept beneath the Proprietary open pit fits a pattern in our database of Australian operators targeting deeper extensions below historic workings, similar to Alkane’s own drilling campaigns at Nagambie and Costerfield, where step‑out holes have been used to convert previously unmined ground into mineable inventory.

    Within the 615 keyword‑matched gold and copper items in our database, New South Wales projects like Peak Hill and Hillgrove stand out for re‑examining historic districts, signalling that brownfields exploration in NSW is increasingly competing with greenfields plays for exploration capital.

    Bradken SmartRoller™ for excavators: reliability and maintenance insights for engineers

    Bradken has launched Bradken SmartRoller™, a digital system that continuously monitors excavator undercarriage roller temperature in real time via remote sensing. By tracking temperature trends as a proxy for wear progression and issuing early alerts, the system allows operators to schedule proactive roller replacement rather than waiting for failure. The approach targets higher excavator uptime, more stable undercarriage performance and lower lifecycle costs for high-hour fleets in abrasive conditions.

    MAV2205 shaft–hub locking devices: bending load insights for conveyor engineers

    MAV2205 shaft–hub locking devices are being engineered specifically for mining conveyor pulleys where high belt tensions and heavily loaded drive or bend drums impose severe bending loads on the pulley shaft, not just torque. By clamping concentrically along the shaft–hub interface, the unit spreads bending stresses more evenly than traditional keyed or welded connections, reducing local stress concentrations that initiate fatigue cracks. For designers and maintenance teams, this supports longer pulley service life, fewer unplanned shutdowns and more predictable performance in high-tension conveyor duty.

    Regis wins McPhillamys court challenge: approvals reset and design notes for mine planners

    Regis Resources has won a Federal Court challenge over its McPhillamys gold project in New South Wales, with the court declaring invalid a Commonwealth heritage protection declaration that had halted development. The 14 October ruling sends the project back to federal Environment Minister Murray Watt for redetermination, reopening the approvals pathway for the planned open-pit operation near Blayney. Geotechnical and mine planning teams can now resume work on pit design, waste rock emplacement and associated infrastructure, pending any new heritage conditions.
