During mining operations, low-grade overburden was extracted from shafts to reach veins of high-grade galena. The galena ore was conveyed via an aerial tram, which carried the material down the slope to the mill. The mining operation created four distinct surface deposits of mine tailings that remain on the property.

ore has been concentrated at a mill near the mine, the lead concentrates are shipped to a smelter. Here, in the case of galena, the first step involves removing the sulfur from the mineral. Roasting in air causes the sulfur to be converted to sulfur dioxide gas. This roasting process converts the lead sulfide to lead oxide.
