fcx earnings out.An interesting read from a major. Lots of open pits in the US and their 48% owned Grasberg in Indonesia, being their monster asset as they are adding a smelter. Looking at the head grades in the US, they are all .30-.40 % which is far below IVN's tailings as Ivanhoe mills at 5% Also explains why FCX's cash costs are pretty high relative to ours.
