Ann: Quarterly Activities/Appendix 5B Cash Flow Report, page-40

if this information's been released in a current format I havent seen it

as i said - until you see the opex cost from the silver stockpile and later the mining - its not supportable to assume the silver will have the same opex as mt boppy

you need to know the relative strip ratio differences for starters, relative trucking distance, if there's going to be pre-transport separation etc

the stockpile wont have any mining costs attaching other than any transport

then once silver mining to do 2Moz pa at the same recovery rate youd be mining/milling roughly ~40% more processed material and so have lower per unit costs because they are split over more gold equivalent ounces.

you may have lower mining and milling per unit costs - or just milling costs.

but nothing in my experience supports the idea you can assume the total aisc as a silver miner would be the same as at mt boppy

that doesnt mean to say it wont be running at a high relative aisc. it almost certainly will be

which is why this is such a high leverage position
