avancos dream mine

Being a novus at copper mines there was an interesting article in todays West Australian about BHP's Escondida
copper mine in Chile after they increased the resource by 129% they are sitting on 1 trillion dollars worth of copper with a mine life of 100 years . The copper contained in the ore is roughly 0.5%
I couldnt find the West article heres the Australian's version

Just 10% of that mine would do us lol
