I think Taub and Nth Tadpura drilling results are only the beginning for MNE. IF (and I repeat "IF") the geology is similar to Medusa Co-O mine located just north of MNE Comval, which is narrow vein mining, then IMO locating the gold veins are probably more complex and require more exploration data and time to map the narrow gold veins.
It took Medusa quite a few years to get where they are. Look at their share price now. The link to narrow vein mining concept (which is quite informative) is in Medusa Mining website is: http://www.medusamining.com.au/narrowvein.html
IMO, LT patience is required for MNE to see whether it will be another hit or not.
