RE: A small caution
Jagmun......
It is apparent you were never a part of any of the Bio-Leaching programs in the area or in other parts of the world.
You are saying U3O8 can only be extracted by milling and that is just not true at all. One of the mines in the area used no milling at all and used 70% undergroung heap leach with just the blasted rock and 30 % surface heap leach with no milling.
Some mines in the area had Underground Bacterial Leach programs using a Stope Flood method with oxygen enhancement.
I think I'll believe the engineers mining cost over yours......thanks anyways!!
Good Luck Longs.....
