Someone used this link in something I was looking at work today. I've been to these 2 towns and around the periphery of the mine but didn't realize just how massive of an operation it was. NASA's quote of 840 million pounds of copper after extraction equates to 420,000 tons if I did the math right. That's a lot of Cu (in my opinion). I wonder how much is left in those local low mountains...??
