MULLAN, Idaho, April 21 (UPI) -- Rescue workers in Idaho say a video camera failed to show any trace of a miner missing for six days when the mine's roof collapsed.
Rescue workers used a camera on loan from the plumbing company Roto-Rooter to inspect the Lucky Friday silver mine in Mullan, Idaho, but found no trace of Larry "Pete" Marek, the Spokane (Wash.) Spokesman-Review reported.
"All we could see was an opening," said Kevin Hirsch, assistant director of the federal Mine Safety and Health Administration. "There has been no contact with the miner."
Rescue workers inserted the camera through a 180-foot drill hole into the area where Marek was working in when the mine's roof came down. His brother was able to escape the falling rock, but Larry Marek has not been heard from since the accident.
The Hecla Mining Co. pumped fresh air through two bore holes Tuesday and has started drilling a third hole. Additional holes are being drilled to provide other openings to the void where Marek might be trapped.
"We're on a fact-finding mission," said Hecla spokeswoman Stefany Bales. "We know how high [the rock pile] is; we know how wide it is; what we don't know is how long it is."
