what cu greades do we need?, page-5

Hi KBJ

Yep, High grades are certainly not always needed to make a profitable mine. I haven't looked into bougainville.

However this was released by rex minerals last month.

ASX and Media Release: 6 February 2013
ASX code: RXM
Australia’s Largest Open Pit Ore Reserve – Hillside, SA
? Maiden Ore Reserve for the Hillside open pit totalling 120Mt @ 0.53% copper, 0.14g/t gold and
12.8% iron
? Eight year Ore Reserve base with 636,000 tonnes of contained copper
? Further increases to the Ore Reserve expected in late 2013
? Updated Mineral Resource Estimate completed for maiden Ore Reserve (Appendix 1)
? Hillside Bankable Feasibility Study (“BFS”) commenced and on track for completion in 2013.

Therefore 1% cu at Mt hardy could be very very profitable if there is enough of it.

Good luck to all.
