The Aldiss Area gold deposits lie within a north-trending ductile shear zone as Karonie Main and West Zones, Spice, Atreides and Tank. It consists of a series of sheared amphibolite facies, mafic rocks, with remnant veining and late stage faulting. A number of ‘late stage’ porphyries intrude the host rock.

The Karonie resource extent consists of 1600m strike; 500m across strike; and 420m down dip and open at depth.

The Tank Artreides resource extent consists of 1850m strike; 800m across strike; and 325m down dip and open at depth.

The French Kiss Project lies on the eastern margin of the Eastern Goldfields Greenstone Province (EGGP) where Archaean volcano-sedimentary sequences are juxtaposed against granitoid-gneissic terranes. The province is characterised by an interconnecting series of north-north-westerly trending greenstone belts surrounded by ovoid to elongate granitoid batholiths.

The geology of the French Kiss area consists of a sequence of NNW-trending amphibolites and associated metasediments. The rock has a strong metamorphic overprint, generally obliterating the pre-metamorphic textures. The lithologies hosting the French Kiss deposit are mid to upper amphibolite facies and a much higher metamorphic grade than the greenschist facies that is prominent elsewhere in the Eastern Goldfields.

Gold mineralisation occurs almost exclusively within the quartz amphibolites and occurs dominantly as native gold. The habit ........

Open pit mining at Aldiss (Karonie, Tank and Atreides) activities were completed during H1 FY22 to facilitate the treatment of surface ore stockpiles to supplement underground mine production.

Development of the Tank South underground mine at the Aldiss Mining Centre commenced in July 2022, with all LOM development completed during the year. Mine production associated with the current Ore Reserve is expected to be completed in Q4 FY24.

The Tank South Underground
The Tank South Underground economic lode is approximately 90m high x 160m long and 12m wide. The mining method selected for the Tank South Underground is sublevel long-hole stoping. Primary and secondary stopes will be mined to allow full extraction of the ore. Primary stopes will be filled using a consolidated fill via boreholes directly from the surface into the crown of the stope.

Stopes will be up to 90m high and 30m long.

Underground access will be established via a portal in the southern end of the Tank open pit with stoping levels to be accessed by a 1 in 7 decline (5.0 mW by 5.5 mH) with levels 20 to 25 m apart. The ore drives are designed at 4.8mW by 4.8mH allowing large loaders onto ore levels to achieve high production rates.

Dilution has been added by applying a 0.5m hanging wall and 0.5m foot wall dilution to each stope. A 95% mining recovery has been applied to account for unplanned ore loss.

Stope ore is blasted using conventual blas ........
