Okay, so these are not the old-style tailings ponds that we're used to seeing.
I only have a minute and a half or so left. You had mentioned carbon capture and storage. I'm from Saskatchewan. It's a big deal in the Weyburn and Estevan areas, and used for enhanced oil recovery.
Can you talk about your new technology on carbon capture and storage and dealing with the greenhouse gas emissions from some of the new technologies that you're using—SAGDE, steam-assisted gravity drainage, as an example—to extract oil sands material?
