I don't know about fools, BLK have bought 600km2 around apex's wiluna gold mine with two gold mines which were mined to only 40m in depth for a cost of $400p/oz(i can't see BLK's cost being to much higher then this considering they have a heap of gold at depth and along strike).
the discussions for BLK to process their ore at apex's plant would be a benefit to both.
