G'day Blthefan,
A pass statement from Nick Poll stated that at $US5.00 lb Ni, then MBN would turn a profit at $us 90 million approx.
Reading all the annoucements on operating costs then a break even figure would be somewhere just over $us4.00 per lb Ni. I've included repayment of interest on the $us190 million loan at 10% eg $us19 million p.a thats about $US0.35 per lb Ni.
