Project Description

DeLamar Mining Company (DMC), a subsidiary of Integra Resources submitted a Mine Plan of Operations (MPO) for the DeLamar Mine Project to the Owyhee Field Office of the Boise District.

The Proposed Action, as described in the MPO, is to mine gold and silver ore by expanding the two existing open pit mines on Florida and DeLamar Mountains. To support mining activities, DMC proposes to construct haul and access roads, two heap leach facilities, three development rock storage facilities, and ancillary facilities while adhering to environmental protection measures identified in the MPO. Upon conclusion of mining operations, the site would be reclaimed in accordance with federal and state regulations. The Proposed Action estimates 2,915 total acres of disturbance, which includes 1,420 acres of previously disturbed areas and 1,495 acres of new surface disturbance. Of the proposed new surface disturbance, 812 acres would be on BLM-managed public lands, 6 acres on state land, and 677 acres on private land. Construction and mining activities are estimated to last 19 years.
