At this stage, for Jervois, the plant project is intended only for the production of copper-gold-silver concentrate.

Copper concentrate (which includes recovered copper, gold and silver) will be sold to the Glencore International AG (Glencore) smelter in Mt Isa.

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-silicate ........

Summary:

The Project will include conventional open cut mining of copper-gold-silver mill feed at Reward and Bellbird open pits, and decline access underground mining of copper-silver-gold mill feed at Reward, Rockface and Bellbird.

Mining Sequence
The mining strategy is to initially mine the Bellbird and Reward open-cuts, whilst underground development is initiated at the Marshall underground. The Bellbird open-cut is commenced first due to the higher copper grades. Development of the Rockface underground mine then commences after Bellbird open-cut concludes in early 2026.

The Marshall underground mine decline will be established from a dedicated box cut in parallel with open-cut mining. Development will commence once the contractor has excavated and supported the box cut as part of early works. The Marshall decline commences in October 2024, three months after open-cut mining commences.

Three years of open-cut mining provides sufficient time to develop the Marshall and Rockface underground mines so they can provide continuous ore supply to the processing plant after the Reward open-cut is completed.

The Reward underground mine development commences after the completion of the Reward open-cut, with entry via a portal within the open-cut. Subsequent development of the Bellbird underground mine in 2032 only occurs once the main development at Rockface underground mine is complete as they share a common decline access (from Bellbird Porta ........
