When you add in the Back-fill, Its almost even, going in and out of the mine. (If Backfill can be transferred that way) Use the small amount of Brackish water to mix backfill @ the bottom, in the mine.
Hope you are correct Putz! We cannot go another year without construction of our mine. IMO, the Dark Horse is firing this trash NioCorp management team and hire a group that will work 60-80 hours a week on NioCorp projects only. In a perfect scenario again, fire this trash team for a nice buyout from a group that’s actually in the mining business. Fingers crossed Summer of 2024 is when this nightmare becomes a pleasant dream!!
