I don't think that figure of fully diluted shares is taking into account unlisted options and performance rights.
At December 31, 2016 (Half-Year report):
-Shares 1,366,433,253
-Listed options 461,973,967
-Unlisted options 172,325,917
-Performance rights 85,000,000
Total 2,085,733,137
Share Placement (fully subscribed):
-SIs 204,600,000 @ $0.005
-CR 800,000,000 @ $0.015
-Options 1,200,000,000 @ $0.005
Total 2,204,600,000 ($19,023,000 raised on full-exercise of options)
I've only just noticed that 20.3 million options were exercised on Dec 13th (the day GMC went into voluntary suspension). And 14.7 million more options were exercised on Dec 6th. Only 5 million options had been exercised in the 3 months leading up to this. It may have been mentioned already, but that looks very suspect!
