I'm referring to an excellent document from the National Energy Board, the 2006 updated energy market assessment. I'd be happy to provide you with the URL for it. Its estimate is that SAGD, the steam assisted gravity drainage, the supply cost, all-in cost, is $18 to $22 a barrel and $18 to $20 for mining. So it's essentially the same cost.
On October 19th, 2006. See this statement in context.
