Project Logistics & B2B Overview
Geographic Location and Topography
The Matilda gold operation is situated approximately 3 km south of Wiluna and 2 km west of the Goldfields Highway, within the arid Mid-West region of Western Australia — roughly 940 km north of Perth. The terrain is characterised by flat to gently undulating semi-desert landscape with shallow overburden, which simplifies bulk earthworks and haul-road construction but imposes severe constraints on:
- Dust suppression across open-pit benches and haul corridors
- Water sourcing for drill-and-blast and processing circuits
- Thermal management of mobile equipment in extreme heat conditions
B2B Lifecycle and Operations
The operation demands a fully integrated supplier ecosystem across both extractive and logistical categories:
- Open-pit services: production drilling and blasting, bulk earthmoving, haul fleet maintenance, and grade-control sampling
- Underground services: contract mining, mechanised longhole stoping support, ground reinforcement, ventilation, and explosives supply
- Processing: reagent supply chains aligned to both non-refractory and refractory ore streams; toll milling arrangements for third-party ore processing
- FIFO workforce logistics: charter flight scheduling, camp accommodation, catering, and welfare services for a fully fly-in fly-out rotation model
Extraction Engineering and Infrastructure
Matilda hosts Archaean orogenic gold mineralisation within the Wiluna Greenstone Belt, presenting two distinct ore types requiring differentiated processing:
- Non-refractory quartz-vein ore: amenable to conventional CIL (carbon-in-leach) processing circuit
- Refractory sulphide ore: requires pre-treatment prior to leaching — driving demand for specialised reagents and plant maintenance services
Underground access is via existing portals and decline ramps, with mechanised top-down longhole open stoping and a modified bottom-up Avoca method with unconsolidated fill. On-site power generation and primary grinding infrastructure support continuous operations.
ESG, Value Chain and Sustainability
Operating within a remote Archaean landscape near Wiluna, the site carries significant Aboriginal Heritage compliance obligations under Western Australian heritage legislation. B2B priorities in this domain include:
- Engagement with Indigenous-owned enterprises for civil works, catering, and site services — aligned to Wiluna's established First Nations community presence
- Dust and water management programs to meet environmental licence conditions in an arid, ecologically sensitive corridor
- Workforce safety governance under the Work Health and Safety Act 2020 (WA), with documented regulatory scrutiny reinforcing the need for rigorous contractor HSE pre-qualification
