Snapshot	Siviour is the second largest Proven Reserve of graphite globally and the world’s largest reported graphite Reserve outside of Africa. Renascor’s upstream mining operation has amongst the lowest projected operating costs in the world. In August 2023, Renascor announced the results of Siviour Battery Anode Material (BAM) study. The BAM study demonstrated that, by integrating the world class Siviour Graphite Deposit with an Australian-based downstream manufacturing facility, Renascor has a clear path to creating a competitive advantage as a low-cost producer of Purified Spherical Graphite (PSG). Nov 2024 - Renascor is progressing early contractor involvement (ECI) to deliver an EPC contract for upstream mineral processing plant and non-process infrastructure ECI project works are optimising and maturing engineering design of the upstream operation in preparation for construction phase. The EPC contract will allow Renascor to move forward to a final investment decision.

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.
