If they truly have nothing, then their pps will not stay high. Remember the dot com craze? It's not a coincidence that UC bought a shell from a dot com to form CMKX.
Right now, diamonds in Canada is the new dot com. Remember, it only takes one big winner (like Diamet) for the suckers to keep coming back. This is the same premise that keeps people buying lottery tickets, even though it's no more than a voluntary tax on people who can't add.
It's all going to come crashing down, just like the dot coms in March/April 2000. Just a matter of time before all the naive speculators in the USA finally wake up to the huge odds against actually finding a diamond mine. Not only that, but the competitors have actual scientists, better land positions, and a real game plan.
And they don't have funny cars.
