Westgold Meekatharra expansion: 61% plant uplift and mine planning notes for engineers

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.

Sandvik underground fleet at Kamoa-Kakula: haulage and maintenance lens for engineers

Sandvik has secured an order from Kamoa Copper SA for 19 Toro® underground trucks and loaders for the Kamoa-Kakula Copper Complex in the Democratic Republic of the Congo, taking the site’s Sandvik underground fleet to more than 100 units. The equipment will support one of the world’s largest underground Sandvik fleets at a single mine, operated by the Ivanhoe Mines–Zijin Mining joint venture. For engineers, the scale signals sustained high-volume, trackless underground haulage and significant long-term demand for OEM parts, maintenance capacity, and fleet management systems.

Metso Durarok™ primary sizer at Yenipazar mine: design and throughput notes for engineers

Metso has secured a €25 million order from Aldridge Mineral Madencilik A.Ş., part of CVK Mining, to supply key minerals processing equipment for the Yenipazar polymetallic mine in Türkiye, including one of its first Durarok™ primary sizers. The package, booked in Metso’s Minerals segment for 2026, will support primary crushing and downstream processing for a deposit containing multiple base and precious metals. For engineers, early adoption of the Durarok™ sizer at Yenipazar will be a reference case for hard-rock primary sizing performance in Turkish conditions.

Volvo Autona / earth autonomous haulage: key takeaways for mine planners

Volvo Autonomous Solutions has launched Autona / earth, a commercial autonomous haulage system for mines and quarries built around an autonomous Volvo FH truck and an in-house developed virtual driver. The package is delivered as Transport-as-a-Service, with Volvo providing the vehicle automation stack, site infrastructure, operational support and maintenance rather than selling trucks outright. The system is designed to plug into existing mine haulage operations, signalling a shift towards OEM-managed autonomous fleets where OEMs assume more responsibility for uptime and performance.
