The Mungari Operation lies within the Kalgoorlie Terrane of the Wiluna-Norseman Greenstone Belt, part of the greater Archaean Yilgarn Craton of Western Australia. The geology is varied over the greater Mungari Operations project area and can be broken up into three broad geological camps being the: • Kundana Gold Camp; • Carbine Gold Camp; and • Kunanalling Gold Camp. The White Foil, Cutters Ridge and Frog’s Leg deposits are situated within the Norseman-Wiluna Greenstone Belt of the Yilgarn Craton, Western Australia. White Foil lies three kilometres to the west of the Zuleika Shear, a regional scale shear zone, and is hosted within a quartz rich gabbro unit which is part of the Powder Sill intrusive complex. The mineralised zone is 70m wide, 400m long and dips to the WSW and WNS at between 50° to 60° and is open at depth The Kundana deposits are hosted by a structurally prepared sequence of sediments, volcaniclastics, mafic and ultramafic volcanic and intrusive rocks typical of the greenstone sequences in the Archaean Yilgarn Block. The deposits are spatially associated with the craton-scale Zuleika Shear Zone. The Zuleika Shear Zone represents the boundary between the Coolgardie domain to the west and the Ora Banda domain to the east. Lithologies at the Carbine-Zuleika Project consist of a series of feldspathic to quartzo-feldspathic tuffs intercalated with shales, siltstones, and sandstones. The Zuleika Shear Zone is the major structural element of the area. The two ........

The Mungari operation consists of the Frog’s Leg, East Kundana and Kundana underground mines, the Cutter’s Ridge open pit mine. White Foil and Cutters Ridge are the open pit mines at the Mungari operations and utilises conventional drill and blast, load and haul methods. White Foil and Cutters Ridge use Conventional open-pit Mining Method (drill, blast, load and haul). 5m x 5.5m decline from portal in pit, then twin declines from 125 metres below surface (mbs) to access north (Mist) and south (Rocket) sections Deepest current level is 700mbs. Underground Mining reserves can be described as conventional sub-vertical open stoping with level spacing of between 20 to 25 meters and accessed from within a previous open pit via a decline ramp. Variations to the stoping method include using pillars or paste fill for stability while some areas deploy hybrid stoping methods to reduce personnel exposure to seismicity (parallel access drives). Kundana (underground mining)Mining method/s: Narrow Vein Long Hole Open Stoping Underground is accessed via two portals from two pits (South Pit & Moonbeam Pit). Link drives underground connect all the ore bodies to allow multiple Ingress/Egress points. Decline dimensions 5.0mW x 5.4mH. Deepest current working level is approximately 602m below sea level. East Kundana (underground mining) Mining method/s: Open stoping with pastefill 5m x 5.5m declines from portals in two pits to five declines which access the Rubicon, Hornet, and Pegasus orebod ........
