It is not shorting    you cannot short TSX stocks that are under $1.00

Likely more to do with Mitchell no longer buying.  He accounted for a large percentage of the volume, so liquidity isn't there.

As for credit facility, I don't see this as a big push to the stock.  They are already over borrowed, so don't need more credit, they need less.

Out right now, but watching where it goes for possible re-entry.
