In response to GS-16, I have evaluated two potential issues that have been raised as part of the EIS process and risk assessment for the proposed Resolution Copper Mine and tailings storage facility (TSF).

Lithostatic stresses and their redistribution around mine excavations are thought to be the dominant driving force in the generation of most mine tremors and rockbursts.

This report presents the results of a site- specific probabilistic seismic hazard analysis (PSHA) and deterministic seismic hazard analysis (DSHA) for the Near West site in southern Arizona.

Thumbnail image of Site-Specific Seismic Hazard Evaluation for the Proposed Resolution Copper Mine report cover

A probabilistic seismic hazard analysis (PSHA) and deterministic seismic hazard analysis (DSHA) were performed for Resolution Copper’s Mine site including the area above the deposit (Mine area) and the area covering the East Plant site (Shafts 9/10).

The contemporary seismicity of the Colorado Plateau based on seismic monitoring in the past 30 yr can be characterized as being of small to moderate magnitude, and contrary to earlier views, of a low to moderate rate of occurrence with earthquakes widely distributed.
