Simple question is "how big is the hole?"

Cliffs intends to open pit mine the deposit... so what is the orientation of the deposit and how far away is the property line.

Would be nice to know the footprint of that mine plan so far and if encroachment into the PRB property is allready engeneered into the mine plan.

Seams to me any development, especially knowing the richest portion of the deposit is at surface on PRB`s deposit, would start on surface on the outcrop and the pit expand from there.
