ROSEMONT COPPER - A BRIDGE TO A SUSTAINABLE FUTURE 21 Geotechnical TITLE: Geologic Hazards Assessment RELEASE DATE: June 2007 PREPARED BY: Tetra Tech Brief Summary: This report presents Tetra Tech’s Geologic Hazards Assessment of the Rosemont Copper project site. Primary conclusions are that there is a risk for rock fall hazards in the western areas of the Project site; there has been previous historic mining activity on the site, which poses negligible hazards to the Rosemont Project; the project site comprises soils of moderate erosion potential; there are no areas of high soil erosion potential; and old, earthen dams scattered across the property may contain soft soils that may prove susceptible to collapse and/or differential settlement. The report includes a total of 13 conclusions and five recommendations. TITLE: Geotechnical Study Report RELEASE DATE: June 2007 PREPARED BY: Tetra Tech Brief Summary: In 2006, Tetra Tech was tasked with providing professional engineering services related to initial site-wide geotechnical studies to support the design of the leach pad and associated ponds, tailings dry stack facilities, and water management facilities for the Rosemont project. The investigations characterized the site conditions of a variety of facilities and areas using borehole drilling, test pit excavating, surface geology mapping, field penetration and hydraulic testing, geotechnical logging of boreholes, geophysical ground surveys, and laboratory testing of selected samples.

The geotechnical recommendations are based on the borings drilled, the subsurface conditions observed, the results of laboratory and field testing, and Tetra Tech’s experience in the area.

Geologic Hazards Assessment of the Rosemont Copper project site.
Primary conclusions are that there is a risk for rock fall hazards in the western areas of the Project site; there has been previous historic mining activity on the site, which poses negligible hazards to the Rosemont Project; the project site comprises soils of moderate erosion potential; there are no areas of high soil erosion potential; and old, earthen dams scattered across the property may contain soft soils that may prove susceptible to collapse and/or differential settlement. The report includes a total of 13 conclusions and five recommendations.

providing professional engineering services related to initial site-wide geotechnical studies to support the design of the leach pad and associated ponds, tailings dry stack facilities, and water management facilities for the Rosemont project.
The investigations characterized the site conditions of a variety of facilities and areas using borehole drilling, test pit excavating, surface geology mapping, field penetration and hydraulic testing, geotechnical logging of boreholes, geophysical ground surveys, and laboratory testing of selected samples.
