RE: Mining experts
RE: Mining expertsIt costs just as much to remove overburden as it does to remove ore. I think the cut off would be how many tons of overburden needs to be removed to get at enough tonnage of ore at a sufficient recovery rate to still make money.
As far as absolute depth, I've seen some pretty deep mines.
Besides which, we are going to be the first open pit potash mine so we are in uncharted waters.
I'm sure they wouldn't be talking about so much if they hadn't already got it figured out.
