If Turcuad is the next target, have they done any gravity survey over it? Doing a gravity survey over this one would have probably saved the expense of the diamond hole and the associated huge sell down, by not hyping it in the first place.
One has to question whether the hype and the cap raising was the main intention all along. It seems that good EM results are everywhere, SIR have 17 close to N-B of which I have mentioned numerous times. They have come up with several duds as well.

I wonder if they ever release the geochems for the area of WM1. Would this have been drilled if the geochems were negative and the gravity normal? It seems to me(from owning shares in another company that drilled a dud, with great EM, Ni/Cu anomalies and magnetics), that these good EMs are just not enough, they seem to throw up many duds, does anyone know what the ratio of duds to hits are for outstanding EM?
