Anon has sold about 1 million since Friday. Those shares are going into multiple hands. It's called accumulation and distribution. With all those shares at their disposal, they still chose to close it at .45 instead of down-ticking it like usual. This has all the hallmarks of a prearranged transfer.
Remember the last MD&A said they have been working on expanding their shareholder base. Without an equity raise this is how it's done. My guess is Anon is a .23 PP holder and is making a nice double, and holding on to their .35 warrants for the rest of the ride.
