The air quality has been pretty good.

It's been difficult and it did flare up. We thought we had it pretty well contained. You've got fire in an extremely enclosed, confined space, and the heat has no place to dissipate.

We feel that we have contained the fire.

We found the two miners that we were looking for for the past 40-some hours. … Unfortunately, we don't have a positive outcome.

Part of the problem … with the fire is we are having roof falls. The heat from the fire is deteriorating the roof.

The mine rescue teams are having a very difficult time with visibility. There's two to three feet (less than a meter) of visibility.
