Copper prices hit a 16-month high yesterday, seeing annual rises of 140-150% for the year, as reported by Reuters on Mineweb.com.
Another story reports that RBS predicts that among the commodities, "copper is the most likely to hit a new record high" in 2010.
Arizona produces about 65% of the copper used in the U.S. The value of copper production in the state helped make Arizona the number one mining state in the nation for the past four years.
