Drilling costs in NVI asked a geologist friend of mine about this. Roughly, drilling a hole 850 meters with the first 250 meters RC drilling followed by 600 meters core drilling would be about $USD 250,000 per hole.
So $USD 3 million would get you 12 holes of 850 meters each. NGE could then drill three 850 m holes per target with the $USD 3 million. Hopefully one of those 12 holes would be the discovery hole. After that I suspect it would get a lot easier to attract money.
