"All horizontal or subhorizontal development openings made in a mine have the generic name of drift. These are simply tunnels made in the rock, with a size and shape depending on their use—for example, haulage, ventilation, or exploration." -- Encyclopedia Brittannica This drift is at the 16 level in the Gilman mine and has been abandoned. Water dripping through the ceiling carries minerals, forming stalagtites and stalagmites.

At 16 level, the ore train would dump rock into the large pit (Grizzly) at the bottom of which was located a jaw crusher. The crusher would send the ore into the ball mill and rod mill where the ore was pulverized to a fine powder. Inside the ball mill, there would be ore and steel balls, approximately 10 in. in diameter. As the mill rotated, the ore was crushed by the balls. Eventually, the balls would wear down and Bob Riggle remembers his dad...
