The Project is located ~90km northeast of Albany in the southwest corner of Western Australia. The Southdown deposit extends approximately 12km in length, under Mining Lease and Retention Licence covering an area of more than 120 square kilometres on largely freehold farming property.

The Southdown deposit occupies the core of a gently east plunging, overturned tight isoclinal syncline with a steeply south dipping axial surface. The deposit is offset by moderately northeast dipping dextral reverse faults and subsidiary steeply south-east dipping sinistral faults. Currently the resource extends for 11 kilometres of the 12 kilometre strike length of the deposit, with variable depths ranging from a surface outcrop in the west, to 480 metres below surface in the east.

Mining will be undertaken by conventional bulk mining methods utilising drill and blast, hydraulic face shovels and dump trucks coupled to a run of mine (ROM) stockpile. Ore will be trucked directly from the blasted faces to either direct tip into the primary crusher or onto the ROM stockpile, as proposed within DFS 2012, but with a reduced mining rate to satisfy a nominal concentrate production rate of 5mtpa.

The final proposed pit is six kilometres long, one kilometre wide and about 370 metres deep.

The reserve within mine lease M70/1309 has the capacity to provide a nominal 5mtpa of concentrate for up to 28 years of mine life. This study uses contractor mining.

The magnetite mineralisation will be crushed in a two-stage process, and progressively ground, sized, and magnetically separated using a dry processing technology to produce an interim dry magnetite product. This will then be mixed with water for final magnetic separation and grinding to produce the final product. Process waste (tailings) will be produced in dry and wet components, with the wet tailings deposited in slurry form into a Tailings Storage Facility, and the dry majority of waste sent to the waste rock dump.

An additional concentrate storage dam will be constructed on site to accommodate a reduction in size of the storage shed at the Albany Port.

The magnetite concentrate will be transported as slurry by a buried pipeline approximately 110 km to a concentrate dewatering and storage facility at the Albany Port. This pipeline will remain sized for a nominal 10mtpa production rate as proposed in the DFS 2012 to facilitate later expansion.
