So are we considered brownfield or greenfield?   Teck mentions advancing those types. It's understandable they might be keeping this on the down-low knowing 25% is currently not in their control. 

Why would they be selling debt rn?

Free up capital for major purchase?

"Longer-term, Teck will progress a suite of meaningful brownfield and greenfield development options, including the Galore Creek project in B.C. and the potential expansion of Trail Operations"
