I wonder if the 600 tonnes means concentrate "The grade of Prominent Hill concentrates has consistently been more than 50% copper", so you need to roughly divide by two. That is closer to the estimated output.
Be interesting to see what costs are, if they can remain in 90c/lb range will be brilliant. Price might have a way to run above $1.80. Still, could fall back - whole sector seems to be moving too hard too fast right now, I'm hesitant to load up on anything right now.
