Racetrack at Norseman: mine planning and mill feed implications for engineers
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Pantoro Gold has extended the mineralised strike at the Racetrack discovery within the Norseman gold project in Western Australia to about 900m, with drilling confirming a continuous high-grade zone from near surface down to 600m depth. The lode remains open to the east, with both infill and extensional drilling tightening geological confidence and pointing to further resource growth potential. For mine planning, Racetrack is now shaping as a key ore source, supporting longer-term underground scheduling and potential mill feed flexibility at Norseman.
Technical Brief
- Drilling at Racetrack is being used to extend strike length along a defined structural corridor.
- Infill drilling is specifically targeting data density sufficient for higher-confidence resource classification and mine design.
- Extensional drilling to the east is testing beyond current geological interpretation limits for lode continuity.
- Near-surface mineralisation geometry supports potential integration of initial open-pit access with later underground development.
- Depth continuity to several hundred metres simplifies planning of stacked underground levels and long-hole stoping sequences.
- A continuous lode geometry reduces requirement for multiple small satellite stopes, improving scheduling and ventilation design.
- Concentrated ore supply from Racetrack can reduce haulage complexity versus relying on multiple dispersed Norseman sources.
- Similar structurally continuous lodes in Western Australian greenstone belts have historically supported long-life underground operations.
Our Take
The 900m mineralised strike and continuity to at least 600m depth at Racetrack, combined with the ultra high-grade 4.94m at 349.14g/t gold reported in the 4 August 2026 item, suggest Pantoro Gold could justify early underground access rather than treating this purely as a satellite open pit feed source.
Across our Mining category, Norseman is one of the more frequently recurring Western Australia gold projects, with multiple pieces on Pantoro Gold’s drilling at Racetrack and Lake Cowan indicating the company is building a multi-centre camp rather than a single-mine operation.
The restart of systematic aircore drilling on Lake Cowan reported on 30 July 2026, alongside the growing Racetrack footprint, implies that any mine planning at Norseman will need flexible processing and scheduling to handle a mix of near-surface salt-lake discoveries and deeper high-grade underground ore.
