Year Published:

Summary: 

Call & Nicholas, Inc. (CNI) was contracted by Augusta Resources in spring 2006 to conduct a geotechnical study focusing on slope-angle recommendations for the Rosemont proposed Rosemont Copper Mine located near Tucson, Arizona. The primary goal of this project was to provide final pit slope angles for a feasibility-level pit design. A secondary goal of this project was to perform fragmentation estimates for use in crusher sizing.

This chapter presents recommended slope angles, fragmentation estimates, and recommendations regarding future work appropriate for a latter stage slope design. Details regarding data collection, laboratory testing, slope stability analyses, and fragmentation work completed as part of this project are presented in subsequent chapters of this report.
