The Environmental Impact Statement analyzes potential impacts associated with Rodeo Creek Gold Inc.'s proposal to develop the Hollister Underground Mine Project (Proposed Action). The proposed Action consists of transitioning from underground exploration activities to a full-scale producing underground gold and silver mine, including continued surface exploration. The Hollister Underground Mine Project is located in the northern end of the Carlin Trend, approximately 47 miles northwest of Elko and 64 miles northeast of Winnemucca, Nevada. The Proposed Action includes underground mining; construction of a shaft, ramp, or raise; haul roads; electric power transmission lines and ancillary facilities; water removal from the underground workings and discharge into Little Antelope Creek and the rapid infiltration basins; backfilling the west open pit with waste rock material; and continued surface exploration. The proposed surface disturbance is 117 acres. The total surface disturbance for the Project is approximately 222 acres. The proposed mine life is 20 years. The angency-preferred alternative is the Proposed Action and Backfill alternative.
