The Site is located in Lake County and is part of the California Gulch Superfund site - Operable Unit 02. It is near Leadville and is northwest of Stringtown, Colorado. The lab was used by an ore mill which was in operation from the early 1970's thru 1986 and has been abandoned. When the mill was operational, ore was pulverized and put through a cyanide leach process for silver extraction. Various chemicals were observed in (the abandoned lab) in containers ranging from 8 ounces to more than 5 gallons in size. Crystals were observed on several containers of Nitric and Perchloric Acid, indicating a possible shock-sensitive situation.
