dj_420. If PH produces:
100k of Cu @ $US3000 per tonne = $US300m p/a
80k oz of Au @ $US800 per oz = $US64m p/a
Total revenue = $US364m
Once fully operating on that revenue Profit around;

cost of production Cu = $1.00 lb
Sale price (assumption) = $1.40 lb
.. profit on $US300m will be $US85.

Cost of production Au = $US543 oz (based on YTD figure Sept08)
sale price (assumption) = $US800 oz
..profit on $US64m will be $US20.5m

TOTAL PROFIT(Cu & Au) = $US105.5m
Assuming exchange rate of 0.67 to $US
PROFIT = $AU157m

At copper price of $US1.80 lb or $US4000 per tonne
Revenue = $US400m
profit = $US177.8m (assuming $1.00 Cost of Production)
Assuming exchange rate of 0.67 to $US
PROFIT = $AU265m
