The Union Mine was active from 1871-1886 with the ore being treated in a 15-stamp mill. In 1896 the Union Gold Mining Company took over operation of the mine and worked it for thirteen years. They also enlarged the mill to 20 stamps some time later it would double to an earthshaking 40 stamps .

The tailings are stored in tailings dams which are lined with impermeable layers. While the cyanide levels in the dam are safe steps are taken to keep wildlife away from the dams. Over time the chemicals break down and the solids settle to the bottom so that the water can be returned to the plant to be used in processing.We then smelt the gold which melts it in a furnace at about 1202 degrees F.

The flotation tailings are sampled by an automatic sampler thickened in a 250-foot traction thickener and discharged to the tailings dam. The concentrates are filtered on three 8-foot by 8-foot drum filters before passing to the smelter. The small tonnage of concentrates to be smelted initially led inevitably to the use of a small blast furnace.
