PeterH,
CGG has some possibilities.
Grade is good at 1.2%
Copper resource at 1.215mt is excellent - translates to a 12 year mine life at 100,000tpa (The only issue here is the distance between the lodes - I have not worked out whether that is an issue or not)
Does CGG own all the resource or are there others that have an interest in it?
