The Republic mine had more than one mill in it's lifetime, starting with the Patrick Clark Mill, which was constructed in 1897 by the Republic mining and milling company to process ore from the Republic Mine. Due to poor results of only 50% recovery, and being overwhelmed with the amount of ore being removed from the Republic Mine, the following year it was replaced by the Red Mill, which used much of the materials from the Patsy Clark. The mine's new owners built the Red Mill with a target capacity of 200 tons per day. Unfortunately, the Red Mill operated only 9 months between 1900 and 1901, and was put back into operation by another new mine owner for two years starting in 1909, and was shut down again until 1937. The Red mill also had a sample mill, to the Northeast of the main 7 level Red mill, that processed samples as they came out of the main haulage adit of the Republic mine.
The White Mill was the Republic Mine's third mill, with both previous mills being plagued with poor recovery results. The New Republic Mining Company built this mill in 1911, with plans to make it a two module, 250 ton per day output, but seemingly only finished one module, giving it a 125 tpd output. The White mill only ran a couple of years as well.
