We have held to the idea that there is hope for the workers and we will continue to work indefinitely.
We haven't reached the place where the explosion occurred. First we have to do all that's necessary to rescue our personnel. Then we can investigate what caused the explosion.
We can't say if there are five, 10 or 50 or 65 who are alive. That's a question, with total respect, that only God can answer.
We would be insensitive if I tell them there's no sign of life. It's a question only God can answer.
There is no sign of life of anyone. No shoe, no evidence of them there.
The working conditions are getting more difficult, they're impeding progress.
The situation is very serious. We have to begin realizing that there are no more survivors.
The situation is difficult but I can't say if the whole mine is contaminated and there are no survivors.
These mines can't operate unless they meet minimum standards.
They are so big that it shows the force of the blast was tremendous.
There were some small, minor things that needed to be upgraded, and we complied with that.
The (tunnel) collapses we found are greater than expected and there are more of them.
If he was away getting something he needed or having a meal, he wouldn't be under the rubble, but we still have to confirm that no one was there in order to move differently or remove debris more briskly.
The conditions are becoming increasingly adverse. It is grave, and being realistic, we think the situation is difficult.
