Nine miners were rescued from a wildcat mine in Peru Wednesday, almost a week after a collapse trapped them 656 feet underground. The miners emerged into daylight wearing blankets and sunglasses, as their eyes hadn't yet adjusted to daylight, according to AFP and BBC News; one reportedly wore an oxygen mask and had trouble walking. While they waited to be rescued the men had been receiving oxygen and food through a giant hose that was in place before the abandoned Cabeza de Negro copper and gold mine partially collapsed Thursday. "All of them are healthy but obviously dehydrated and dizzy," Peruvian President Ollanta Humala said, warning informal miners to avoid dangerous abandoned mines. Peru has a huge informal mining industry.
