Waste Rock Dump Investigation, Pilbara, Western Australia

Okane has completed the installation of over 90 instruments to depths of 40 m within waste dump landforms as part of a long-term monitoring and assessment program.

Instrumentation was installed using the sonic drilling technique and include galvanic oxygen probes, soil matric potential sensors, temperature sensors, and vibrating wire piezometers. The gathering of data allows for the conceptual model of the hydrology and geochemical evolution of waste rock dumps to be both tested and refined.
