Taken from page 8 of today's Broken Hill presentation.... and yep, it does say 150years..... ------------------------- 40 billion tonnes of in-situ magnetite could be defined by future exploration
But, for safety, lets assume that only 50%, say 20 billion tonnes of mineable magnetite ore can be ultimately defined through futher exploration with scope for say 5 pits mining 50 Mtpa ore and beneficiating 10 Mtpa of concentrate each.
Which suggests a total regional output of 50 Mtpa of magnetite concentrate gives a foreseeable 150 year regional life of mining @ nominal 250 Mtpa ore mining rate.
