Proposed Mesa J iron ore development - Pannawonica

Proposal description: 

The proposed Mesa J mining development is a continuation of the sequential development of proven iron ore reserves along the Robe River Valley.

This proposal relates to an iron ore mining operation of 600 million tonnes over a period of approximately 20 years. The major components of the proposed development include:

  • Site preparation, including overburden removal and stockpiling of ore which will be extracted along the rail alignment to be constructed on the eastern escarpment of the new Mesa J deposit.
  • Construction of a 10.4 km railway to the Cape Lambert- Pannawonica railway, including a new rail yard, a causeway and bridge across the Robe River and a load-out facility adjacent to the new mining area. The proposed railway alignment is along the eastern edge of Mesa K, crossing the Robe River at its confluence with Jimmawurrada Creek, along the eastern edge of Mesa J, then south over flat terrain beyond the mining area.
  • Construction of new facilities and associated infrastructure to support the mining operation.
  • Provision and upgrading of services (i.e. roads, power) to the mining area. Realignment of the gravel road from Millstream to Deepdale is required due to the location of the proposed pit and railway tail track.
  • Development of facilities to enable de-watering of that portion of the ore body below the water table.
