Whats AUM worth ?
At 46million Tonnes @ 1.6% copper is 736,000 tonnes of copper metal.
Mt Isa Mines paid $400million for Ernst Henry Mine 10 years ago with 66million tonnes @ .6% copper or 396,000 tonnes of copper metal , copper 10 years ago was $2000us per/tonne and now its worth $5000 per/tonne , based on that deal it makes AUM worth 2Billion..do your own sums. $2B divided by 46million shares thats $43.47 a share so .40c looks like a good buy.
