Riverina Gold Mine

Riverina Gold Mine is situated in the Ularring district, Goldfields-Esperance region of Western Australia, within the highly mineralised Murchison–Goldfields greenstone belt. The site occupies semi-arid, flat-to-undulating terrain at low elevation, characterised by sparse mulga scrub and calcrete-dominated soils. Ambient temperatures routinely exceed 45 °C in summer months, imposing critical thermal management requirements on heavy mobile equipment, hydraulic systems, and surface infrastructure. Dust suppression and heat-load planning are non-negotiable operational priorities for all surface contractors and equipment vendors operating on site.

Riverina Gold Mine is an actively producing asset within Ora Banda Mining's Davyhurst Gold Project, operating continuously 24 hours per day year-round across both underground and open pit fronts. The workforce is structured on a FIFO rotation model, with Kalgoorlie-Boulder serving as the primary logistics and personnel hub. Camp support services — including catering, accommodation, and occupational health — represent active B2B procurement categories. Supply chain vendors must accommodate remote delivery schedules, with lead-time planning critical for reagents, ground support consumables, and mechanical parts.

Underground operations utilise a decline-access methodology with continuous ore extraction from sub-level stoping panels. Key engineering procurement categories include:

• Primary ventilation systems: forced-air raise boring and auxiliary fan networks to manage heat and diesel particulate at depth
• Ground support: resin-grouted and mechanically anchored rock bolting systems, mesh, and shotcrete supply
• Dewatering and humidity control: sump pumping, in-stope drainage, and underground humidity monitoring
• Surface processing: CIL gold processing circuit requiring ongoing reagent supply (cyanide, lime, activated carbon)
• On-site dual-fuel power generation supporting uninterrupted 24/7 load demand

Operations within the Goldfields-Esperance region require rigorous Aboriginal Heritage compliance under Western Australian heritage legislation, with active engagement protocols prior to any ground disturbance. Ora Banda Mining's procurement framework prioritises partnerships with local Aboriginal-owned enterprises across service categories including civil works, environmental monitoring, and site services. Vendors seeking preferred supplier status are advised to demonstrate Indigenous engagement credentials and community benefit commitments. Environmental obligations include tailings management, progressive rehabilitation planning, and water stewardship in a low-rainfall, high-evaporation operating environment.
