While stamp mills were used in the early days, they were soon supplanted by jaw crushers and ball mills. At the mill, ore was crushed by a primary jaw crusher, wet ground in a secondary ball mill, classified by a Dorr rake classifier, and the fines concentrated on Deister tables. Gold concentrates were amalgamated and retorted.
The Bradford Ridge Mine was the most extensively prospected mine in the district and was the site of a 10 stamp mill contained gold, with some arsenopyrite.

Earlier, stamp mills did the same thing. Formed into bars, gold ready shipment. On the surface, ore crushers smashed the rock into yrlnch pebbles.
A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled …
