Unless you're already a PRB investor, who else knows about PRB (other than the rogue traders)?
Why isn't PRB utilizing social networks with slick 30 sec ads, as well as the bigger pubs like Globe and Mail and Bull and Bear (US investors)? Having a booth at a show is almost worthless (giving a presentation to a large group of investors at a conf is another story).
If you anticipate putting out a PEA later this year - October? - you will have to lay the groundwork by putting a floor under the SP.
