Westgold Meekatharra expansion: 61% plant uplift and mine planning notes for engineers
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Westgold Resources plans a $100 million brownfields Meekatharra Expansion Plan in Western Australia to lift processing capacity from 1.8Mtpa to 2.9Mtpa, a 61 per cent throughput increase at its central gold hub. The scoping study centres on upgrading the existing Meekatharra plant rather than building a new facility, signalling higher utilisation of current crushing and grinding circuits and greater ore draw from regional underground and open-pit operations. For mine planners and plant engineers, the uplift will drive changes in pit scheduling, haulage profiles, and tailings storage requirements.
Technical Brief
- Scoping Study defines MXP as a brownfields upgrade of the existing Meekatharra processing hub.
- Brownfields approach implies tie-ins to existing crushing, grinding and gold recovery circuits rather than greenfield duplication.
- Higher plant utilisation is expected to necessitate tailings storage expansion and potential upgrades to water and power supply.
- MXP reflects a wider pattern of WA gold producers debottlenecking central hubs instead of building new plants.
Our Take
Westgold Resources has recently been converting non-core Western Australian gold assets like Peak Hill and the Chalice project into cash, equity and royalties, which likely underpins funding capacity for a $100 million brownfields expansion at the Meekatharra processing hub without over-gearing the balance sheet.
The planned lift in throughput at Meekatharra aligns with Westgold’s post-2024 integration of Karora Resources, suggesting the hub is being positioned as a central mill for a larger, more consolidated ore feed rather than a stand-alone operation tied to a narrow mine footprint.
With Sodexo Australia already locked into a >$100 million, five‑year services contract across Westgold’s Western Australian operations, the Meekatharra Expansion Plan (MXP) is likely to benefit from existing camp and site services capacity, reducing execution risk on the non-process infrastructure side compared with a greenfields build.
