EPA Superfund Program: CIMARRON MINING CORP., CARRIZOZO, NM

Superfund Site Profile

The Cimarron Mining Corporation site is located in Carrizozo, New Mexico. The site includes two areas: the 10.6-acre Cimmaron Mill site, located on the north side of Highway 380, and the 7.5-acre Sierra Blanca Mill site, located east of Highway 54. Milling operations took place from 1960 to 1982. Operations at the Cimarron Mill recovered iron and precious metals from ores. In 1979, use of cyanide to extract precious metals from the ore began. Operations at the Sierra Blanca Mill site recovered a variety of metals from ore transported to the site, although the process apparently did not use cyanide. Milling operations contaminated soil, sediment and groundwater. Following cleanup, operation and maintenance activities and groundwater monitoring are ongoing.
