Gold mine, operating since 2002. Owned by Dominion Mining Ltd.
Located at Mobella Station, 740 km north of Adelaide, on the northwestern margin of the Gawler Craton, 165 km west of the Stuart Highway.
The lode systems are contained within a feldspar–quartz–cordierite–garnet–biotite gneiss.
Metamorphism to 800°C is believed to have melted and remobilised gold in this deposit, resulting in a low Ag content of the gold (only 2%) (Tomkins and Mavrogenes, 2002; see also Elements 5 (2009) p. 298).
Note on the mineral list: unspecified bismuth minerals and tellurides are also mentioned in the PIRSA PDF.
17 valid minerals.
