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 ‘Flora Dora’ deposit is hosted within the lower ‘Maxwells’ member of the Mount Belches group and the ‘Santa’ deposit is hosted within the upper ‘Santa’’ member both members are located in the southern Eastern Goldfields Superterrane, Yilgarn Craton, Western Australia.

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.

Underground Mining
Mount Monger underground mine production for the year totalled 668,039 tonnes at 5.5 g/t for 118,790 contained ounces (FY19: 674,510 tonnes at a grade of 5.2 g/t Au for 111,876 contained ounces).

The Daisy Complex produced 270,531 tonnes at 6.4 g/t for 55,353 contained ounces, with production sourced from the Haoma West, Lower Prospect and remnant mining areas. Development to access the Easter Hollows lodes located ~350 metres to the west of existing underground development is underway with the target area reached in Q1 FY21. Once established, the Easter Hollows zone will provide a shallower mining front at the Daisy Complex and provides a significant exploration opportunity, with 1,000 metres of known plunge extent and improved drill access to target infill and extensional opportunities.

The Mount Belches underground mines (Maxwells, Cock-eyed Bob and Santa) produced 397,508 tonnes at 5.0 g/t for 3,437 contained ounces, representing 53% of the underground mine ounces at Mount Monger. The commencement of the Santa mine in the last quarter of the year has resulted in a third shallow underground ore source in the Mount Belches area with production in FY21 expected to be ~23,000 ounces. Production from the Mount Belches Mining Centre is scheduled to increase to 80,000 – 90,000 ounces in FY21. Once underground access is established at Santa, ongoing RC and diamond drilling will focus on infilling and further extending the identified high-grade zones immediately to the north, south and below the current mine plan and outside the current Santa Ore Reserve.

Open Pit Mining
Open pit mining at Aldiss (Harrys Hill, French Kiss and Karonie) totalled 1,087,500 tonnes at 2.2 g/t for 78,360 contained ounces (FY19: 744,590 tonnes at 2.0 g/t Au for 46,673 contained ounces). The increased production reflects the deeper higher grade zones of the Harrys Hill pit and commencement of production at French Kiss in the period.

The Harrys Hill mine was completed in April 2020 with total material movement of 822,292 bcm for production of 03,649 tonnes at 2.0 g/t and 45,130 contained ounces.

Mining at French Kiss was completed in May 2020 with total material movement of 1,210,798 bcm for 271,156 tonnes at 3.3 g/t and 28,772 contained ounces.

Open pit mining activities transitioned to Karonie South in the last quarter of the year following completion of mining at Harrys Hill and French Kiss.

Mining at Karonie South was focused on overburden removal and waste stripping with a total of 1,960,100 bcm mined in the year for 112,695 tonnes at 1.2 g/t for 4,457 contained ounces. Ore tonnes and grades will progressively increase from Q2 FY21 as the investment in waste stripping improves ore access

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.
