Looks like U.S. markets have bigger bulls than our bears. I'd be very worried trying to short a company down -97.18% since June, 2007 with such bullishness. I think you need to be very brave to sell something with positive cash flow and 80 mill cash at bank, and in the face of it's main product (zinc) set to rise +65% by 2016.
Good luck. You'll need it.
