In two years time based on what are proven copper assets and today's spot prices:

50,000 T Cu x $8000/T / 0.75 $/US$ = $533M
20,000 oz Au x $630/oz / 0.75 $/US$ = $17M
Total cash flow = AU$550M per year

Costs:
7,000,000 T of ore X $16.50/T = $112M

= $438 M profit per year less admin, exploration, etc, etc.

Perhaps a $3B market cap by then? = $11 per share.
$0.50 per share dividends perhaps? (OK, slightly less with some 20% share dilution).

Copper prices may go lower, but gold could go higher.

And then the fun starts with Uranium and further exploration.

I'm holding out for retirement...
