First Quantum Minerals offers voluntary retirement to Cobre Panama workers, sources say
The mine, one of the world's top sources of copper, was shut down in November, hours after Panama's Supreme Court declared its contract unconstitutional.
Copper rose Tuesday, on the back of an agreement by French banks to rollover Greek debt. France introduced a “creative” solution to the Greek debt-crisis on Monday, suggesting that banks roll over some Greek debt for 30 years, in order to help the struggling economy avoid insolvency.
