Mine Life6 years (as of Jan 1, 2019)
Mining operations at FGO during 2019 were focused on three main ore sources, namely the Yarlaweelor open pits, the Starlight Underground Mine and residual low-grade stocks in the region.

Summary:

The Fortnum deposits are Paleoproterozoic shear-hosted gold deposits within the Fortnum Wedge, a localised thrust duplex of Narracoota Formation within the overlying Ravelstone Formation. Both stratigraphic formations comprise part of the Bryah Basin in the Capricorn Orogen, Western Australia.

The Horseshoe Cassidy deposits are hosted within the Ravelstone Formation (siltstone and argillite) and Narracoota Formation (highly- altered, moderate to strongly deformed mafic to ultramafic rocks). The main zone of mineralisation is developed within a horizon of highly altered magnesian basalt. Gold mineralisation is associated with strong vein stock works that are confined to the altered mafic. Alteration consists of two types: stockwork proximal silicacarbonate-fuchsite-haematite-pyrite and distal silica-haematite- carbonate+/- chlorite.

The Peak Hill district represents remnants of a Proterozoic fold belt comprising highly deformed trough and shelf sediments and mafic /ultramafic volcanics, which are generally moderately metamorphosed (except for the Peak Hill Metamorphic Suite).

Geological interpretation:
- The Yarlarweelor mineral resource extends over 1,400m in strike length, 570m in lateral extent and 190m in depth.
- The Tom’s and Sam’s mineral resource extends over 650m in strike length, 400m in lateral extent and 130m in depth.
- The Eldorado mineral resource extends over 240m in strike length, 100m in lateral extent and 100m in depth.
- Low-grade stockpiles are of various dimensions.
