Information on Unpatented Mining Claims
One of the issues identified to be analyzed in the environmental impact statement (EIS) is the presence of unpatented mining claims that might overlap with the proposed project footprint. Information about the unpatented mining claims associated with the proposed action were included in the General Plan of Operation submitted by Resolution Copper (figure 1.3-2 and appendix A). In May 2019, additional unpatented claim information was requested from Resolution Copper for the other alternatives, including:
- Alternative 4 – Silver King
- Alternative 5 – Peg Leg, including east and west pipeline corridor options
- Alternative 6 – Skunk Camp. While the tailings storage facility itself is located on private and Arizona State Trust lands, unpatented claims still could be affected by the north and south pipeline corridor options.
The purpose of this memorandum is to document the receipt of these files for the project record.
