In 1902, a processing plant was built at the mine site and between the years 1903 and 1917, the mine produced up to 100 tons of arsenic (Luttrell, 1966; Young, 1956). The arsenic produced here was used to manufacture insecticides (Hess and Graton, 1911). The processing mill was dismantled in 1919 and mining has not recurred since (Luttrell, 1966).
