2007 Sustainable Development Report
Resolution Project Profile | Chapter Contents
Rio Tinto Group
The Resolution Project is quite possibly the largest single
development project in Arizona, and will have a significant
impact not only on the company’s host communities but
also the state, through taxes and employment. Project
expenditures since inception are $232 million, with figures
expected to rise significantly over mine life.
The Resolution Project consists of two sites: one north of
Superior called the West Plant site, which was the location of
mining and smelting activities of the historic Magma Mine
from 1910 until 1996; and another at Oak Flat (known as
the East Plant site) that was the main location for mining
beginning in the 1970s. The West Plant site is the focus of
major cleanup efforts by Resolution Copper. Expenditures on
site rehabilitation to date total $13.3 million, and will near
$50 million by the time the work is completed. The No. 9
shaft at the East Plant site is the focus of future development.
