I've seen many valuations over the last 2 years around mid $4 to $5 from various punters here and on other forums . Obviously depends on the price of gold. The figures i have mentioned were crafted on around USD1250 for gold with NO added value for the philipines venture (FY11 to FY12).
Personally I've been holding tight for $4.50 mark since the $0.30c days.
good luck
OGC=winner........ imho.
