The Granite Mountain Mining Company constructed two mills adjoining the mining operation know[n] as the Ruby Shaft. These structures, Mill A and Mill B, housed a total of 70 stamp mills which processed ore. Stamp mills were used to crush the ore so the metal could be separated from the base material by amalgamation of mercury. The stamp mills were very noisy and produced a great deal of dust. The mines and mills all operated six days a week.

When the production of the Ruby Shaft exceeded the capacity of Mills A and B in 1889, the Granite Mountain Mining Company built a mill in Rumsey to handle the additional ore. They named this new operation Mill C.

I Saw The Marker

Almost completely illegible now from weather damage. Glad that someone catalogued it so I can read the marker text. Did not take a picture, unfortunately. Neat location.
