We don't want to make mistakes. However long it takes, we want to get it right.

We've got rescue teams under way, and we're trying to get some holes drilled to get air samples.

So far, we've got no communication.

A lot of it depends on the circumstances and how big you are and how much air you suck.

There's no one in the mine at the moment. There has to be some rehabilitation work done at the mine for the underground investigation. The ventilation has to be restored.

It's no secret that, historically, the mining industry has been inherently more dangerous than most other occupations. I don't see where this one incident would have more of a detrimental impact (on recruitment) than any other incident in the past.

It's not like we have manpower to burn, but we've got to do a better job of getting around to more mines.

With an explosion you want to know where and how it was initiated. We want to know how the fuel came to be, the buildup of gases, how that came about. That's not uncommon in a sealed area.
