Ann: Epanko Mineral Resource Increases by 40%, page-11

"A detailed mineralogical study of the Epanko rocks in order to determine the timing of mineralisation and key metamorphic events was completed by CSIRO (Perth).
CSIRO has confirmed the graphitic rock has undergone extreme metamorphism with the mineralogy consisting predominantly of calc silicates. At Epanko scapolite (a calc silicate mineral) forms porphyroblastic aggregates which give the rocks a “cheetah” like texture as shown in Figure 3.
The commercial benefit of this favourable mineralogy is an easily liberated graphite concentrate from a low cost simple process that is saleable graphite without further processing steps. Other key benefits include:
High percentage of large flake and higher carbon grade
Low levels of in-situ deleterious elements
The degree of metamorphism determines the graphite crystallinity and it is important to recognise this provides its physical and industrial properties.​

A favourable mineralogy ultimately determines recovery and quality which drives strong project economics."
