Strip Ratios - PEA
Strip Ratios - PEAWe are approaching PEA and one of the key topics will be the strip ratio that is finalized in the study.
This is actually where size does matter and the small footprint of CH6 will hit hurtself in the fact that it does have to mine more waste material for each metre it goes deeper.
CH7 is a bit better (larger), but it doesn't have the margin to sustain it as well.
Here is a post with related information --
Strip Ratio Post The biggest quesiton will be...when does it make sense to go underground. You can make the deepest pit possible..but if you have to move a small planet of waste to do it...it doesn't make a lot of sense.
LONG...PGD
