[Updated at 11:26 a.m.] Rescuers at the Chilean mine expect to begin the rescue of 33 trapped miners during "the last quarter" of Tuesday, Mining Minister Laurence Golborne said.
"We hope to finish the day with at least one miner on the surface," he said.
[Posted at 11:21 a.m.] The concrete base built for the winch system at the San Jose Mine in Chile has hardened, paving the way for the rescue of the miners to start tonight, Mining Minister Laurence Golborne said.
The winch that will pull the trapper miners out in Chile will extract them at .7 meters (2.3 feet) per second, Health Minister Jaime Malanich said. In case of emergency, the speed of ascension can be increased to 3 meters (9.8 feet) per second.
