Draft Environmental Impact Statement


Book Description

This Draft Environmental Impact Statement (DEIS) analyzes potential impacts associated with Newmont Mining Corporation's (Newmont's) proposal to develop the Emigrant Project (Proposed Action), a proposed open pit gold mine located approximately 10 miles south of Carlin, Nevada. Newmont submitted a Plan of Operations for development of the Emigrant Project in February 2004, revised May 2004, and re-submitted with further revision in March 2007. The Proposed Action provides for development and operation of an open pit mine; construction of a waste rock disposal facility, run-of-mine heap leach pad, permanent engineered stream channel, ancillary support facilities; and reclamation of surface disturbances in the Emigrant Project Area. Approximately 1,418 acres would be disturbed by mine-related facilities, including 248 acres of private land and 1,170 acres of public land (including 442 acres of split estate). The Emigrant Project would have a 14-year operational mine life and produce approximately 92 million tons of ore and 83 million tons of waste rock. Closure activities may continue for a period of up to 30 years after mining activity is completed. The Agency Preferred Alternative is the Proposed Action with mitigation.







Copper Flat Copper Mine


Book Description

The New Mexico Copper Corporation (NMCC) has submitted to the BLM the Copper Flat Mine Plan of Operations (MPO), dated December 2010 and revised June 2011, for the proposed reestablishment of a poly-metallic mine and processing facility located near Hillsboro, New Mexico on BLM-managed public land. The mine was previously owned and operated by Quintana Minerals Corporation (Quintana). Under the Federal Land Policy and Management Act of 1976, as amended, and supported by National Environmental Policy Act analysis, the BLM will decide whether to approve the MPO with modifications, and if so, under what terms and conditions. NMCC's Proposed Action includes an open pit mine, flotation mill, TSF, waste rock disposal areas, a low-grade ore stockpile, and ancillary facilities. Proposed land reclamation efforts during mine operations and following mine closure would significantly improve an existing brownfield site. The previous Quintana operation worked at a 15,000-ton per day (tpd) rate; the Proposed Action increases that throughput to 17,500 tpd. Additional alternatives are identified for rates of 25,000 tpd and 30,000 tpd. The "No Action" Alternative describes conditions expected to occur if there would be no new mining activity.
