Ann: Substantial Walford Creek Resource Upgrade, page-10

MOD was acquired for A$170mil with 590kt contained Cu (plus silver credits). The project was more advanced with completed feasibility studies but it was also in Botswana. AML have a total of 830kt Eq contained Cu in the best mining jurisdiction in the world and are valued at nearly half MOD.

Naturally feasibility studies will need to be done to prove the economics of AML's project, but with grades of ~2% Cu - I believe opex will be very competitive. Surely some big names are sniffing around here.
