If you follow the price drop you will find it to be caused by one seller, can't say who but you can see it is one seller. Scotia on the Canadian side is just flipping from US to Canada and making about 0.05 per share.
What I see is for the past 2 weeks E-Trade as being coming in the market on the US side and selling loads of stock into the close (usualy in the last hour). This is what you can see from market data.
Don't know why , might be a liquidation of a fund or new managers at a bank that don't like penny stocks and want their profit. In these market cash is king and when you need it you sell what you can... All speculation, but what is not is the fact that there is no massive (lot's different big selles) panic selling.
Dundee as bought some (last week on a cross) but not all, I tought they did. My mistake
All I can say is when the seller is done the stock will almost for sure go back to 0.30 even without news.
So if you think the stock is going down because of mass selling or the project going bust then sell and move on.
But in my humble opinion it would be a big mistake.
Alway do your own DD
For for disclosure I am long the stock.
