"Not sure about the cost of a rig. I would think the most important part would be the experienced crew to run the rig."
Kent, you're absolutely correct. An experienced crew is essential.
If I recall correctly, Noront Resources had terrible difficulties and delays recently, due to a crew's inexperience in operating the very specialized, custom built equipment of one of NOT's new Deep Drills. Noront has not acknowledged this, but it was rumored in serious circles.
Eagerly awaiting some fine GNH news,
