The sudden increase in volume from less than $20,000 traded all day less than a month ago to over $700k traded yesterday on 'no news' is a bit odd.
I agree this is probably in context of a run-up pending CR.
A polished balance sheet is a necessary safety net but dare to dream for a second: The long term MACD has just turned positive, RSI was the highest its been YTD. Additionally, the director filed for cashing in of 240K worth of options in context of this timing? Tax related? Suspecting near term gain i.e. re-inclusion into ASX300? Re-inclusion into ASX300 would probably take this back into the low teens; changing of the royalty scheme (unlikely anytime soon) would be higher but is unlikely.

I am 70% down over 1 year in this particular stock which is a 3.3x (or $600M MC before dilution) to break even. I hope those who have endured through this period are rewarded with the success of this company.
