After Rescue Hole No. 1 broke through into the mine, rescuers signaled the trapped miners by tapping on the drill steel with a hammer, and a faint response was heard. The miners had been taking turns walking every 10 or 15 minutes down the passageway from their high ground location to check the area where the drilling sounds were coming from. When Hileman and Foy made the trek on Saturday at about 10:15p.m. their cap lamps were dim, but that is when they found the drill opening and Hileman alerted the others.
