Report: The Emma mine is located in section 15 (T14N R08E). There were no mill tailings located at the site. Five hundred twenty cubic yards of waste rock was estimated. The waste rock contained elevated levels of silver, arsenic, cadmium, copper, manganese, lead, antimony, and zinc. There were no discharging adits, filled shafts, seeps, or springs present at the site. Squaw Creek cuts through the site and releases of sediment were observed. Samples from Squaw Creek (up stream and down stream) contained exceeding MCL's for cadmium, copper, nickel, and antimony. The EPA action level for lead was also exceeded. A collapsing loadout structure and a slope that was unstable (above the caved adit) were potential safety hazards.
