 | | Conditions at Proposal (July 1999): The Upper Tenmile Creek Mining Area is located in the Rimini Mining District, southwest of Helena, Montana, and consists of abandoned and inactive hard rock mines producing gold, lead, zinc, and copper. |
 | | The site may include the entire drainage basin (i.e., watershed) of Tenmile Creek and its tributaries that are upstream from five City of Helena drinking water intakes: Tenmile Creek; Beaver Creek; Moose Creek; Minnehaha Creek; and Walker Creek that serve an estimated 24,569 people in the City of Helena. |
 | | These mines were reclaimed during a 1989 reclamation project by the Montana Department of State Lands, Abandoned Mine Reclamation Bureau (MDSL/AMRB) (currently known as the Montana Department of Environmental Quality (DEQ), Mine Waste Cleanup Bureau); however, there may still be sources of hazardous substances in the Upper Tenmile Creek Mining Area. |
