The front end of the business for the three members we have--Shell, Suncor, and Syncrude--is mining. It's truck and shovel. It's the mining of the bitumen. The back end of the business is the separation and the crackers, the production of sweet crude, etc., and then it's into the petroleum business, and downstream, in Suncor, all the way through to gas stations, etc.
Part interest in our connection is with the mining component of the business and the best practices at that end in terms of energy efficient removal of materials, reclamation of landscapes, energy efficiency in that process, etc.
