encase the whole length, those whole 2,300 feed to prevent rock falls during the extraction operation or whether they say, know, we think that rock and granite is pretty solid and only encase the most unstable part, which is the first 100 yards or so. interestingly, on that point, just a few moments ago, before we came to air, the health minister came out and was passing through camp and made some comments to reporters saying that he believed the extraction process could come as early as tuesday. now, that would tend to suggest, then, that engineers would only encase with steel tubing the first 100 yards, and that will mean that the miners can come home much sooner than later, kyra. that s good news. karl, we will be monitoring every minute. thanks. great bass fishing on one side, a potential death sentence on the other.
