I don't know it's could go anywhere depending on the next hole
imo, the current $70m is not cheap, but if the theory proves correct [zone mineralisation model suggesting Cannington look-a-like being tested with this hole] it's could easily be a $1b company
conversely, if the Zn is not there, and it's not Cannington #2, it's likely sub $30m pretty quick
hard to do, but gotta buy em when they young. sorry I can't be more help
