Pangea, would I be correct in assuming you are an ex-industry person that comes on to HC to impart your considerable industy knowledge to many unsuspecting punters here. If so are there occasions where you might get it a bit wrong because of lack of all information.

For example the Kevitsa and Aitik mines inside the arctic circle are incredibly low grade but profitable, much lower grade than N-B and now Succoth(perhaps). Is it possible that with different costs, mine size etc. Perhaps higher cap costs but larger mine, with lower costs, with high grading the first few years to pay off the higher cap costs?
To me what I can see is the high cost of fuel ending up being almost 50% of ongoing costs based on generators for the plant, and diesel equipment, compared to Boliden at Aitik (with .2% Cu) running nearly 40mt/a on electricity that costs them 3.7c/kwh??
