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.

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.

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.
