Apologies - not intended to be any criticism of you, as you say, you are just quoting what's in the report.
I am just saying that the report itself makes one heck of a presumption and broad sweeping statement by saying that a standalone underground mine is uneconomic, first of all why the focus on going underground right away, and secondly were other options or mining techniques considered?
Pretty bold statement to make in my opinion, given they haven't even closed off J1 or J2 down plunge or along strike in at least several directions.
