The gold mineralisation at Majestic and Imperial deposits is hosted by a quartz diorite stock on the western side of the regional scale Yindarlgooda Dome. Gold zones are characterised by open breccias, quartz veins and zones of foliation associated with pyrite + chalcopyrite + pyrrhotite, overprinting silicasericite alteration. The highest grade gold-copper zones at Imperial are characterised by a micro breccia sulphide fracture network fill with semi-massive sulphides that almost completely overprints the silicasericite alteration, in discrete zones that are up to 5m true width.

Located 33km north north-west of the Randalls Mill.

Mining from the Majestic open pit commenced July 2016 and will continue until Q2 FY2018.

Ore production from the Imperial open pit is scheduled from Q2 FY2018.

All ore from the Mount Monger Operation is processed through the 1.3 mtpa Randalls facility, located 65 km south east of Kalgoorlie and is 15 km from the Daisy Complex.

Gold recovery consists of both a gravity circuit containing two gravity concentrators an intensive cyanidation unit and hybrid CIP circuit comprising two leach tanks and six adsorption vessels. Gold is stripped from the loaded using a pressure Zadra type elution circuit consisting of two elution columns and the gold is subsequently recovered from the cathodes of the gravity and electrowinning cells.
