Rescuers are bringing in more equipment to dig out Larry Marek. A section of roof caved in on him and his brother last Friday, his brother got out.
The latest info is that a large diamond drill will be used to drill a hole through the debris, to try and determine if Marek is alive. It could take two days to drill through the 185 feet (56.3 meters) of dirt.
Rescue efforts are slow because the size of the collapse was underestimated. Rescuers are also waiting for parts, so they can use a bigger drone digger.
The company that owns the Lucky Friday mine, Hecla, has a good safety record going back to 2000. But there have been accidents at other Idaho mines. Last June a miner was killed when a slab of rock fell on him, while he was working at the Galena Mine.
