1. Chilean Mill and Jig Marker

Inscription. The vibrating jig liberated the heavy minerals from most of the lighter waste material as water was forced upward through a screen with a shot bed consisting of lead shot or old nuts and bolts. Pulsating action combined with water caused the lighter particles to float away and the heavier material to settle to the bottom.

A Chilean Mill used steel rollers to crush the ore to a fine consistency as it washed into the mill. The slurry, dirt and water mixed together, escaped through screens along the sides of the pan and into a gutter that carried it to the jig for further processing.

Erected by U.S. Forest Service and Idaho Department of Parks and Recreation.
