Ann: Exceptional performance from Graphite Battery Anode Testing, page-131

Hi Was wondering if anyone believes if this is any point of concern ?, is this common , What happens if we can not get to 50 %? what are the successes of optimisation. would this hold back any potential offtake partners until 50% optimisation is clarified or defined ?

Thanks in advance !

The tap density is lower than best specification. A high tap density is preferred as it results in
batteries with higher capacities. More optimisation test work will be undertaken to see if the
tap density can be increased further. This optimisation test work will be undertaken both during
production of the graphite concentrate, and also during processing into spherical graphite
product.
The yield is relatively low at present compared to other graphite. Normally it is possible to
achieve yields approximately 50%. The yield for the Springdale material was in the 30 to 40%
range. It is probably the high proportion of fines in the feed product that is separated off by the
classifier which generates the lower yield. This will also undergo optimisation in future testing
to improve yields.
