Proposal description

Audalia Resources Limited (Audalia) is proposing to construct and operate a vanadium, titanium and iron ore mine approximately 100 kilometres (km) west of Norseman, Western Australia (WA). The Medcalf Project, located in the Bremer Range, Lake Johnston region of Western Australia, approximately 470 km east south-east of Perth.

The proposal includes three separate open pits and requires up to 650 ha of native vegetation clearing. Mining will occur above groundwater.

The proposal includes the following key components:

  1. Mine Development Envelope (898 ha); and
  2. Haul Road Development Envelope (1,633 ha).
