The Avon Mill was in Nevada Gulch just west of the
Gilpin main line. A two siding spur served the mine. There was
also an Avon Mine higher up on Quartz Hill.
The mill used amalgamation and concentration processes.
It had 1 jaw crusher, 30 stamps with outside amalgamation plates, 6 Gilpin
County bumpers, 1 Wilfley table. Output was somewhere between 60 and
200 tons.
