Tamarine Limestone

The Tamarine limestone and limesand operation (site code S0019572) is situated within the Phillips River Mining Field, Goldfields-Esperance Region, Western Australia. The terrain is characterised by low-relief lateritic plains with fine red-dirt overburden — a critical operational variable. Airborne dust suppression and high-grade filtration systems are non-negotiable requirements, as particulate infiltration accelerates wear rates across all rotating and pneumatic equipment deployed on site.

Operating under the Ravensthorpe – First Quantum project umbrella, Tamarine supplies limestone and limesand as process inputs — likely for pH control and reagent use in adjacent nickel hydrometallurgical circuits. The acute dependency on local mechanical workshops cannot be overstated: remote location and single-commodity supply chains mean unplanned downtime carries disproportionate cost penalties. B2B vendors offering on-call field service, rapid parts logistics, and mobile maintenance units hold a decisive competitive advantage here.

Material handling at Tamarine involves open-cut quarrying of competent limestone and unconsolidated limesand horizons, demanding a dual-mode extraction strategy. Conveyor belt systems manage bulk transfer across processing stages, with abrasion-resistant belting and idler assemblies subject to accelerated degradation from siliceous fines. Engineering procurement must prioritise:

• Heavy-duty conveyor components rated for abrasive carbonate-silica blends
• Dust containment hoods and transfer point sealing systems
• Wear-resistant liners for chutes, hoppers, and crusher feed zones
• Mobile crushing and screening units adaptable to variable limesand gradations

As a satellite operation feeding First Quantum's Ravensthorpe processing complex, Tamarine is subject to Western Australia's Mining Rehabilitation Fund (MRF) obligations and DMP progressive rehabilitation mandates. Tailings and overburden management follow strict tailings facility containment protocols aligned with ANCOLD guidelines. ESG-aligned vendors should be prepared to demonstrate:

• Dust suppression and water management compliance documentation
• Proactive landform rehabilitation scheduling per approved Mine Closure Plans
• Biodiversity offset reporting aligned with WA Environmental Protection Act requirements
