EG, Improving economics-
That is easy:
waste rock that is actually generating ore revenue.
M&I resources that remain outside the 2013 pitshell that was unsafe to extract but later was proven to not be the case.
Improving metal recoveries and minelife
The better CAPEX&OPEX forecasts just from removing the double edged sword of waste rock costs vs revenue.
Using the 5% discount rate ROV case for post feasibility advanced deposits near production like SC.
The billions of times of metal not yet included in resource numbers.
Plus all other aspects I did not mention like future metal prices n exchange rate.
I just improved project economics!!! :)
