Hydrology and Waterways Study for Mine Road Upgrade

Pilbara Minerals Limited engaged Agilitus to undertake a hydrology and waterways assessment of the Pilgangoora Mine Site and Wodgina Mine Access Road, including the conceptual design of floodway crossings. Following the conceptual design phase, Agilitus’ geotechnical and civil engineering teams worked collaboratively with Pilbara Minerals to progress detailed design and site investigations for the delivery of the road upgrade project. The operation consists of two processing plants – the Pilgan Plant located on the northern side of the Pilgangoora area produces a spodumene concentrate and a tantalite concentrate; the Ngungaju Plant located to the south produces a spodumene concentrate. The Wodgina Access Road is the main access road to the Pilgangoora Mine Site and is situated approximately 110km south of Port Hedland in Western Australia’s Pilbara region. The design scope involves upgrading 24 km of the Wodgina Road to a sealed road to facilitate increased haulage capacity via super quad road trains. This includes 11 major floodway crossings,12 km of site access and haul roads, and a new intersection at Great Northern Highway. When complete, the road upgrade will improve the efficiency and safety of transporting critical minerals to Port Hedland to meet the increased demand for resources to enable the global transformation toward clean energy and a sustainable future.
