Summary:

The Jervois Project lies within the eastern part of the Arunta Region, which forms part of the North Australian Craton. Base metal mineralisation at Jervois is hosted by a lower-to-middle amphibolite grade metasedimentary sequence of the Bonya Metamorphics.

The Jervois Project area lies on the south-eastern edge of the Jervois Range. The proposed mining activity is focused along the range of low hills and rises running approximately north to south through the middle of the Jervois Project area, forming a J-shape. This distinctive J-shape of the Bonya Schist outcrop has been interpreted as the result of re-folding of pre-existing folds, and as a drag feature to a regional Jervois fault that lies to the west. The more resistant lithologies feature as a series of hills that prominently define the J-structure on aerial photographs and satellite images.

The mineralisation style is generally stratabound and contained within steeply dipping lenticular bodies (lodes) of calc-silicate, garnet-chlorite-magnetite rock and garnet-magnetite quartzite, within a thick succession of spotted andalusite-cordierite schist and quartz-sericite-magnetite schist. The mineralised sequence has a strike length of some 12km and a stratigraphic thickness up to about 600m.

Copper-gold-silver mineralisation mostly occurs as massive to semi-massive layers of sulphides. Sulphides also occur in associated quartz veins and as thin interlayers in meta-mudstone and calc-silicates.

KGL recognise two main styles of mineralisation and alteration/metamorphic mineral assemblages:
1. Lower grade, primary syn-depositional or stratabound sulphides and
2. higher grade, structurally controlled shoots representing both remobilised stratabound syngenetic mineralisation and a possible late tectonic intrusion-related mineralising event.

The major mineral deposits in the Jervois Project area – Reward, Bellbird and Rockface – are generally sub-vertical strata-bound lodes hosted within the rocks that form a distinctive, kilometre-scale, J-fold.

The Bellbird deposit strike over 1.3 km. Within the structural corridor lie three defined lodes ranging from approximately 200 m to 500 m in lenght and plunge moderately North. Three mineralised structure and two oblique lodes lie to east of the Bellbird structure.
