Because bag holders know that this is going to be highly manipulated by day traders until the mine is fully permitted. Swoop in, buy at .61, and sell it off at .70. Lots of people have made money on PLM over the past decade doing this. Look at NAK--same thing is still happening there and its in the 2.XX range. IMHO, PLM is way more a sure thing than Pebble but thats just me. Hell, even when it was trading a million shares a few weeks ago it barely went up and was taken down immediately. This may never end for PLM until they are sold or partner.
