Snapshot	The Siviour Graphite Deposit is the second largest Proven Reserve of graphite globally and the world’s largest reported graphite Reserve outside of Africa. Renascor’s PSG is intended for export to lithium-ion battery anode manufacturers worldwide. All major regulatory approvals are in place for the mine and downstream facility. The DFS and early site works, including electrical grid upgrades, have been completed, and the project is advancing toward Final Investment Decision. Early Contractor Involvement improves engineering and confirms capital cost estimates. Grid connection capability has been enabled through upgrades to the SA Power substation and overhead network. A demonstration facility is under construction to validate a lower-cost, more efficient ex-China PSG purification technology, supported by a successful large-scale production run using concentrate from a 730-tonne bulk sample processed with Renascor’s optimised flowsheet.

Summary:

The graphite mineralization at Siviour is hosted within Meso-Proterozoic metasedimentary rocks sediments of the Hutchison Group.

The graphite mineralization is within a nominally 30 m-thick band of pelitic schist that occurs within a thick calc-silicate sequence.

Mineralisation hosted within a sequence of micro-gneiss, metasedimentary rocks and schists.
The mineralisation is generally tabular, oriented east-west and forms an undulating surface that dips shallowly to the southwest, in the southern area, and more steeply to the north in the northern area. In the west the strike of the mineralisation has been interpreted, from geophysical data, to swing sharply towards the north and in the east is partially dislocated by a fault zone although, again from geophysical data, is anticipated to extend further to the east to Siviour East and Paxtons.

Geological interpretation was completed on a sectional basis, from which geological surfaces were interpolated for the dominant lithologies and the top and base of the mineralised horizons. These interpretations were used to constrain the grade estimation. There are no alternative detailed interpretations of geology.

The main mineralisation domains were defined using grade constraints in conjunction with geophysical data. A nominal cut-off grade of 3% TGC was used to define boundaries between the higher-grade mineralised horizons and the and weakly-mineralised or un-mineralised horizons within the micro-gneiss, metasedimentary rocks and schists.

The main zone of mineralisation extends over 2.9 km east-west and 1.6 km north-south. The horizontal width ranges from 550 m within the central area, at the Siviour Prospect, to 125 m south of Buckies.
