Also called the Harold Mill, the Tintic Standard Reduction Mill stands on the west slope of Warm Springs Mountain at the southern edge of Genola, Utah. Built about 1920 by the Tintic Standard Mining Company, the concentrator processed silver ores only a few years before closing in the mid-1920s. Concrete and steel mill structures remain on the hillside. The property was listed on the National Register of Historic Places in 1978.
