Deposit
The Miralga Creek Project consists of three separate deposits (Miralga Creek, Sandtrax and Grants) on the northern margin of the Panorama Greenstone Belt within the East Pilbara Terrane. A fourth prospect, known as Miralga West is located some 4 km west of Miralga Creek.

Miralga Creek
The Miralga Creek deposit is hosted within the Cleaverville Formation, part of the Archaean age Gorge Creek Group. The iron formation of the Cleaverville Formation forms a prominent east-west striking ridge which dips steeply to the north. The deposit is bound to the north by the Lalla Rookh Sandstone.

Grants
The Grants deposit is hosted within the Archaean age Cleaverville Formation of the Gorge Creek Group and comprises BIF and chert, separated by thick sequence of quartzites and meta-felsic sandstones (Lo, 2013). Except in the east, it is uncertain whether this is all Cleaverville Formation as the Formation has been described by Lo (2013) as very siliceous and not a true BIF due to the rare iron bands within the chert.

Sandtrax
Sandtrax is located close to the Abydos project area and occurs in the same geological setting. Sandtrax is reported by Crowther, 2012, to occur within the Paddy Market Formation, however later mapping (Sweeney, 2014) confirmed that the Sandtrax deposits occur within the Cleaverville Formation of the Gorge Creek Group. It is bounded to the north by the Lalla Rookh sandstone.

The Miralga Creek DSO Project comprises the mining of iron ore from five satellite pits within three discrete mining areas, spread over 30 km, as follows:
1. Miralga East (3 pits), 35 km north-east of the now closed Abydos Mine, with the three pits located along an east to west trending ridge.
2. Miralga West (1 large pit), 22 km north-east of Abydos, with the pit on a north-east to southwest trending ridge.
3. Sandtrax (1 small pit), 7 km north-east of Abydos, with the pit along an east–west ridge.

The pits will be mined in a staged manner by a small mobile mining fleet.

Mining will be conventional drill and blast, load, and haul methods. It is expected that approximately 8 Mt of iron ore will be mined above the groundwater table over approximately 4 to 5 years with an average strip ratio of 0.8:1 (waste:ore). The proposal is to maintain approximately 2 Mtpa ore supply with a mobile mining fleet, on a day shift only basis for seven days a week. New infrastructure in addition to the existing Abydos operation will include open pits, waste rock dumps, extension to haul roads and run of mine (ROM) pads. Topsoil and vegetation will be removed, where possible, during early development and stockpiled in adjacent well-drained areas. The orebodies crop out at surface and do not require pre-stripping. Topsoil stockpiles will be managed appropriately and the materials will be used during rehabilitation.

Water will be supplied from the existing Venturex and ALRE borefields. Current licensed volumes enable approximately 2 GL per annum to be abstracted. The Project requires up to approximately 0.9 GL per annum, well within the current approved volume. There are no other significant users of these borefields. The borefield are proposed to supply the Project’s construction, operational (i.e., product conditioning and dust suppression) and potable water requirements.
