WINNEMUCCA, NV – The Bureau of Land Management (BLM) has published a Notice of Availability in the Federal Register for the Draft Environmental Impact Statement (DEIS) to analyze and disclose environmental impacts associated with the proposed Mackay Optimization Project expanding gold mining operations at the Marigold Mine. This notice opens a 45-day public comment period that will end on July 5, 2019.

The BLM will hold public meetings on June 12th at the Winnemucca Convention Center, 50 W. Winnemucca Blvd, Winnemucca, NV from 6:00 PM to 8:00 PM and on June 13th at the Lander County Courthouse, 50 State Route 305, Battle Mountain, NV from 6:00 PM to 8:00 PM.

The Draft EIS analyzes environmental impacts associated with Marigold Mining Company’s proposal to expand the existing Marigold Mine and extend the life of the mine, which employs about 400 people, for up to 10 years. Impacts to be considered includes water resources; air quality; vegetation resources (including noxious weed species and special status species); wildlife; grazing management; cultural resources; Native American cultural concerns; recreation, and social and economic values.

The mine is located in Humboldt County, Nevada approximately 35 miles southeast of Winnemucca. Proposed changes to its operation would encompass about 2,055 additional acres (approximately 800 acres of public land and 1,254 acres of private land). The plan modification would combine existing open pits into three larger pits. The pits are proposed to extend below the historic water table necessitating dewatering of the groundwater and include rapid infiltration basins for recharging the excess water down gradient of the pits. Waste rock storage areas, heap leach pads, and other supporting facilities would be expanded in association with the pits. In addition, amendments to two associated rights-of-way needed to accommodate the proposed mine changes are evaluated in the DEIS. These rights-of-way include relocation of a portion of the Buffalo Valley Road and the existing 120-kV power line operated by NV Energy.
