The Milford stamp, or A.G. Campbell, mill was erected in the fall of 1873 at a cost of $45,000 to work the ores of the Old Hickory Mine. In 1873-74, the mill ran successfully for five months using a 60 horse power engine, two horizontal boilers, a Dodge rock-crusher, wooden pans, iron settlers, and a retort. Freighters bringing ore from the east mountains had to ford the river, giving the place the name Milford. Arvin M. Stoddard was the first settler in Silver Desert Camp, Beaver County.
