Ann: RIU Conference Presentation, page-58

My take on that article is that the analysts are proving in a roundabout way that it is anybody's guess where the copper price is going. Personally I think that it will eventually reach about US$14,000 per ton due to supply vs demand from the renewables etc - but above US$14k per ton will make renewable projects too expensive. BHP are talking about buying existing copper projects rather than developing new ones - which is probably smart as it gets them producing assets quicker and doesn't increase supply so price will stay higher.
