Rosemont Copper
Rosemont Copper is the name of a copper mining project in the permitting process under the direction of the United States Forest Service.〔(US Forest Service EIS )〕 The project is located in Pima County, Arizona, in an undeveloped area approximately 30 miles southeast of Tucson. The nearest established communities are Sonoita, Patagonia, Sahuarita, Green Valley, Corona de Tucson, and Vail. Opponents argue that the mine will damage water and air quality and hurt the local tourism industry.〔(Save the Scenic Santa Ritas - Rosemont Arguments )〕 Proponents argue that the project will create jobs, generate tax revenue and reduce American dependence on foreign sources of copper.〔(Southern Arizona Business Coalition - Rosemont Benefits )〕
==Mining Plan==
In 2007, Augusta Resource Corporation, Rosemont Copper's parent company, filed a Mine Plan of Operations with the U.S. Forest Service for a proposed open-pit mine in the Santa Rita Mountains.〔(Augusta Resource - Mine Plan of Operations )〕
The property contains three mineable copper/molybdenum ("Cu/Mo/Ag") skarn deposits: Rosemont, Peach-Elgin and Broadtop Butte.〔(Rosemont shows investors new sites - Arizona Daily Star - December 8, 2011 )〕 Annual production of copper is expected to reach 243 million pounds, which would equal approximately 10% of total U.S. copper production. The mine is expected to produce 5.4 million pounds of molybdenum each year along with 2.9 million ounces of silver and 17,000 ounces of gold.〔(Rosemont Copper Mine - What We Mine )〕
The Mine Plan of Operations contains details about all manners of the project, including the location of access roads, water conservation, open-pit plans, ore processing and transport, production schedule, drilling patterns, waste rock storage, air quality and dust control methods and land reclamation.〔(US Forest Service EIS - Mine Plan of Operations )〕 It is currently under review by the United States Forest Service.
