RE:Front End LoadedCH-6 is basically a highly valued condensed small in size deposit.
Rule of thumb if that a 500 metre depth underground mine can send 2 to 2.5 million tonnes of material up a single ramp without traffic issues and ventilation issues getting the way.
We will never see a 2 mtpa mill at Chidliak. Maybe a 1 mtpa mill or a 1.5 mtpa...and if they upsize it to that point...they will get material from multiple pipes...not just CH-6.
We will never need a Shaft at CH-6...even if the pipe extends to 1 km down at its current breadth...it will still be a truck and ramp and haulage system....so deepening the mine in the future is easy.
Long term, you can still get 500 ktpa up the deep ramp while you blend it with other pipes.
Short term, open pit and 500 metre deep...not a problem to feed the mill.
I still like my stockpiling concept --
Stockpiling concept at Chidliak The article is still very relevant to what they will be doing this year.
LONG...PGD
