That just adds to the mystery of how this happened. It was inspected as required by the regulations, and it was clean, and an hour later, there was this explosion.

That just adds to the mystery of what happened when the production crew went underground.

It's a very slow, very careful, methodical process.

This is not a rookie crew underground. So we're just trusting that their training and their mining instincts have kicked in immediately.

That's why this is such a slow process.

These miners are experienced, they are well-trained. We are just praying they had an opportunity to put their training to use.

It was the readings they were taking of the atmosphere indicating they were not equipped to go further.

We will expect to be there quick enough so that food, water, those sorts of issues probably will not come into play.

We don't want to be energizing anything if it's in an atmosphere with combustible gases.

We don't know where the miscommunication occurred, and we don't think it's particularly important.
