300 bucks should be pessimistic as long as AUD/gold stays above A$1650. If they produce 160k oz this year and average A$1650 gold price then I'd think closer to A$400 should be the acheivable margin but I'd rather go with A$300 which gives some cushion to either total costs being higher than A$1300 and/or AUD/gold slipping back a bit.

Still lots of "ifs" and "hoping" but everyday AUD/gold stays near A$1700 is a day that ensures Norton should have a bumper year and most importantly be able to accelerate debt repayment.
