RE: PDG vs. EXS
RE: PDG vs. EXSWhy is this discussion digressing to a "whizzing contest" about ore grades at fundamentally different properties?
Porcupine West has an initial 43-101 that states "the grades encountered could in theory support a potentially profitable future underground mining operation."
Magino has a feasibility study due next year for an "open pit" project.
Open pit mining uses different cutoff grades than underground mining. This is usually due to a large difference in the ore extraction costs.
