First point, looks like there are approx 8M $0.52 warrants remaining. More than half of those 8M warrants are held by a small number of Canadian investors who do not need to sell stock to exercise the warrants. They will put up the cash. 

So with that said there is not a large overhang. Period.

Secondly, all this nonsense about some insiders converting a relatively small amount of options and a small insider sell.

These are employees who work for a living and have bills to pay just like everyone else. And life is too short so why not enjoy some well earned profits while you can.

It would not surprise me at all if those exercised options, now shares, will be sold in the market in the coming weeks.

Life is short, enjoy it while you can.

Any investor who thinks insiders should sit on options and not collect a profit after all the hard work, is a selfish mindset.

Let the hard work and commercialization plan continue so we can benefit from a SP that will inevitably climb.
