Tomboy, why would wsa prod be any larger ( lower cost per unit)...

Tomboy, why would wsa prod be any larger ( lower cost per unit) than sir when wsa does approx 6.5kt per qtr.. this is less than sir projected up to 28kt + 11ktCu per annum

You can argue till you are black and blue but projected net cash of $3.5b over initial 10yr mine with approx $400m sensitivity to each $1us lb PN either way..at worst let's peg the $3.5b back to $2.5b (on lower PN) and SIR will still be a cash machine

Offtake agreement is next cab off the rank and that should give a good indication of where things are headed
