Hi Spidy,
$45 bitumen would be below their Total Cost.
Fortunately price of bitumen moved up recently above $52/bbl.
Here is their cost, based on the recent production numbers.
Operational cost: $22.5/bbl
Maintenance Capex to sustain operations ($30 million/year): $6/bbl
Future Interest expenses ($20/bb/ in Q1/2011): $16.5/bb
Average hedges loses ($25/bbl in Q1/2011) : $2/bbl
1/2 of the G/A expenses (another 1/2 cover by MRC): $4/bbl
Total cost : $ 51/bbl
PS: The cost of the pump replacement you were wondering is not included in the Operational cost. It is included in the maintenance Capex.
