Having been involved in the survey and exploration of this mine, I wouldn't want to be either the one being rescued or being part of the team doing the rescue. For those who have not been underground here, its about 15km maze of passages. I am really glad it wasn't too serious.
When timed permits I will upload some 3d images of the mine workings for those who might be interested.
If it can't be grown it has to be mined.
