At least two miners are killed and more than 30 others are trapped underground after a training tunnel collapsed at Freeport McMoRan's (FCX -0.9%) massive Grasberg mining complex in Indonesia. Output at Grasberg, the world's second largest copper mine which also has the world's largest gold reserves, is not expected to be significantly affected, FCX says.
