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.

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

We're making an effort here to contain the fire. We've seen it from a couple of different places but we don't know the extent of it. The teams are in the process now of trying to fight that fire and get it under control.

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

I don't think we fully know the obstacles we're facing. How much smoke is there? What are the difficulties of traversing through there?

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

We feel that we have contained the fire.

We're working as hard as we can ... to find those two miners.
