1.You wil probably need to talk to a broker to see who is shorting and it will be more than one. 2. Shorting happens continously, so it will be at a range of prices. 3. The shares will probably be covered when the price moves up.
As for your comment that DML shuld be flying I suggest you have a look at the rest of the resource sector. As for the shorters leaving comment, it is part of the Markets so I think you might be in for a long wait lol...
