$5 copper quick math Assuming $4 cu needed for breakeven... shitty but lets say that. Also lets be pessimistic at 3000tpd (well below nameplate 5ktpd). Again let this be lower bounding scenario to set minimum expectation.
$1 cu ($5 -$4 AISC) will generate profits of $2204/tonne * 3000 tpd * 365d/yr = $2.4B/yr
thats pretty good.
