Fair enough Bodo288. I'd have to re-check pervious reports, but I think the cobalt is associated with the copper. Luckily we have long list of metals in these layers. I'd like to hear some opinions about the geological processes which produced AML's deposit. From previous reports the various sulfide metals were transported to the fault and deposited there. The mineralisation has been compard to Mt Isa whose metal deposits came from black smokers (undersea vents of super heated brine enriched with metals). I'd be pleased if posters would like to share their understandings?
