Caledon Resources 2006

Charles,
For Xstrata, Cook was a less profitable small mine. They needed Minyango (which is adjacent to Cook) to make the operation worthwhile. Unfortunately for them, Caledon got there first. Consequently, Xstrata have sold Cook to Caledon (but maintained an interest by marketing the coke). Following from this, Caledon update Cook with production boosting technology (which they own) and shore up the Minyango site. By 2009 the Cook/Minyango operation has become a large, highly profitable business.
In steps Xstrata who snap the lot back up.
