Economic ModelThe model the may 20, 2011 N1-43-101 report uses has an average coal price of $139 (after approx 40 per ton) in transport costs for the 20 year period. It prices the coal at an appropriate discount to the Queensland benchmark which hit 330 in Q1 2011 so the lower quality coal is taken well into account. If coal prices remain high as forecast the NPV will increase significantly.
There is a table (#23-6) on page 23-38 in the report that is the basis for the coal price in the model but I cannot tie in any of the numbers from the model back to this report. The model has lower numbers that whats in the table. For example for 2013 after deducting transport costs the table has coal prices as follows:
Base case 150 per ton
Low case 134 per ton
High case 187 per ton
The model uses 136 per ton (clean ton after transport). I would have expected to see the $150 which is the base case. I could not agree any other years. The numbers used in the model are between the low and base case from the table.
Does anyone know why the numbers are different - probably some netting or presentation ??
