SnapshotFortnum Gold Operations (FGO) encapsulate the historic mining centres of Labouchere, Fortnum, Horseshoe and Peak Hill.

Mining output is currently dominated by the Starlight underground mine with supplementary, free on surface low grade stocks providing a blended feedstock to the plant.

The FGO processing hub incorporates the 0.9 Mtpa Fortnum carbon-in-leach (CIL) processing plant.

A new hybrid (gas, battery, solar) power facility at the Fortnum was commissioned in October 2023.

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 stockworks that are confined to the altered mafic. Alteration consists of two types: stockwork proximal silica-carbonate-fuchsite-haematite-pyrite and distal silicahaematite-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).

The Starlight ore system is mined underground and has a number of lodes varying in strike and width from 5-150m and 1-40m respectively. The wider zones resulting from the bulking of lodes.

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.
