"Teck is spending an estimated US$6.6-billion to expand its Quebrada Blanca copper mine in Chile, a project short-handed as QB2. That’s up from US$5.2-billion when Teck launched the project four years ago. When completed later this year, QB2 will be the world’s second-largest copper mine, with a 28-year lifespan and potential for further expansion."

So from 4.7B to 5.2B to now possibly 6.6.B???

How important is our carried-interest for anyone buying our 25%? 

Ask Sumitomo who needs to pay, on top of the 1.2B US initial payment, 1/3 of all the additional capex cost.

IMO.
