The Daisy Milano mine lies between the Christmas Flats and Lorna Doone Pits and contains several mineralized structures including the one which is also exposed in the Christmas Flats Pit. Gold is hosted in narrow quartz veins at or near contacts between
NNW-trending porphyritic dikes and the surrounding andesite which is either pillowed or brecciated.

SW, and cross-cut by moderately N-dipping tourmaline-bearing quartz veins, post-dating gold mineralization (and also found in the Lorna Doone Pit). Gold-bearing quartz veins are usually steeplydipping WSW, parallel to the dikes but sometimes dip more gently near faults. These quartz veins are typically very narrow (<1 cm to 5 cm) and can define ptygmatic folds within porphyritic dikes. The ore-shoot in the mine plunges moderately to SE.

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.

The Cock-eyed Bob is hosted within the upper ‘Santa Clause’ member of the Banded Iron Formation (BIF) of the Mount Belches group. The Mount Belches group is located in the southern Eastern Goldfields Superterrane, Yilgarn Craton, Western Australia.

The iron formation is a silicate/oxide-facies unit with over printing sulphides, and has undergone metamorphism (upper-greenschist facies) and deformation (two generations of folds). The gold deposits are hosted in both the hinge zone and along the limbs of a regional scale, chevron folded BIF package.

Gold dominantly occurs as inclusions of native gold and/or electrum within or around pyrrhotite, magnetite, and arsenopyrite, and economic mineralisation is typically restricted to the BIF horizons.

Aldiss deposits Main Zone, Harry’s Hill, Tank/Atreides, Italia/Argonaut, French Kiss and Spice are hosted in amphibolites and metasediments striking north/south and dipping steeply to the west. The vast majority of the gold mineralisation occurs in amphibolite rock that has metamorphic foliations generally running subparallel to the sedimentary layering. The gold mineralisation dips steeply to the west with a variety of plunges from 30° to the north at the Karonie main zone deposit to 30° south at French Kiss.

Daisy Complex is currently mined using handheld and mechanised methods. Airleg development and stoping is undertaken in narrower ore zones while in all other areas ore production is derived from single and twin boom jumbo development and selective longhole stoping.

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

The Mount Belches mining centre is located 18km from the Randalls Mill and currently comprises the Maxwells and Cock-eyed Bob underground mines.

For Cock-eyed Bob Mechanised Longhole Open Stoping has been adopted as the primary stoping method.

Multiple open pit ore sources and identified targets: Harry’s Hill, French Kiss, Karonie South, Spice, Tank, Atriedes, Main Zone.

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.
