Err.... there is a good reason - SIM still need to define a resource. I think that once they get along this path, and given the sheer size of their tenements in the best "U" patch in the best "U friendly" state (SA) next to Beverly, AGS and MTN, and they get a sniff of uranium, the market cap will charge to meet that of MTN and AGS and then leave them in their wake.
This could easily be a ten dollar stock within 12-24 months!
