Why put in a stink bid? You would only want to do that if you actually want to own this company. To me it looks like this is a dead horse with no cash to do anything.
The recent run is probably being engineered so that ROZ can do a financing. I expect you will see the sp hold and possibly move a bit higher until the financing.
Then again, they could just have decided to fold operations and the big boys are playing this to get out if they are not already out.
GLTA and be smart with your money, gamble only what you have to lose.
