Gold mineralisation within the Cracow field forms along various broadly north-south striking corridors. Historical gold mining focused on the Golden Plateau deposit which yielded over 850 thousand ounces of gold between 1932 to 1992. Current underground mining, referred to as the Western Vein Field, is located immediately west of Golden Plateau. The Cracow project area gold deposits are in the Lower Permian Camboon Andesite on the south-eastern flank of the Bowen Basin. The regional strike is north-northwest and the dip 20° west-southwest. The Camboon Andesite consists of andesitic and basaltic lava, with agglomerate, tuff and some inter bedded trachytic volcanics. The andesitic lavas are typically porphyritic, with phenocrysts of plagioclase feldspar (oligoclase or andesine) and less commonly augite. To the west, the Camboon Andesite is overlain with an interpreted disconformity by fossiliferous limestone of the Buffel Formation. It is unconformably underlain to the east by the Torsdale Beds, which consist of rhyolitic and dacitic lavas and pyroclastics with inter-bedded trachytic and andesitic volcanics, sandstone, siltstone, and conglomerate. Gold mineralisation at the Cracow Operation is hosted in the Lower Permian Camboon Volcanics (intermediate volcanics) on the south-eastern flank of the Bowen Basin. The Camboon Volcanics consists of andesitic and basaltic lava, with agglomerate, tuff and inter-bedded trachytic volcanics. Gold mineralisation is hosted in steeply dipp ........

Mining activities during the financial year were focused on improving development and backfilling rates, testing the limits of mining capacity. The mining method used at Cracow gold mine is underground mining with backfill. A variety of stoping methods are used. The most common method is bench stoping with dry backfill with an upwards extraction sequence known as modified avoca. There are 15 separate deposits being mined, all by underground methods. The Ore Reserve estimate reported is a consolidation of the estimates for the fifteen deposits. Fourteen of the deposits are accessed via the Cracow mine infrastructure. The Roses Pride mine infrastructure is three kilometres to the North of the main Cracow mine. Several mining methods are used for the extraction of stopes at Cracow: • Modified Avoca. This is the primary method of extraction at Cracow. A bottom-up extraction method. Stopes are backfilled with dry rockfill; • Uphole retreat. A method used on the top level of an orebody or in a sill pillar. Stopes remain open as there is no backfill horizon; • Benching. Used on the bottom level of an orebody to extract ore that would not be economical to mine conventionally (capital costs associated with another level below); and • Transverse stoping. A method used in wider (>15m) areas to ensure maximum recovery. Design parameters are: o Minimum mining width = 1.5m. This width has been achieved utilising a zipper pattern. Widths equal to or greater than 1.8m are mined with di ........
