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.

I would also like to know more about how the tap density can be improved or how difficult that maybe. Matt sounded fairly confident that the yield could be increased to that 50% benchmark without much trouble. He touches on it in the proactive interview.
