Sources: Geological Survey and U.S. Survey. The Mineral Industry of Arizona By Madan M. Singh This chapter has been prepared under a Memorandum of Understanding between the U.S. Geological Survey and the Arizona Geological Survey for collecting information on all nonfuel minerals.

In 2014, in the State of Arizona (fig. 1), the value of nonfuel In 2014, the production quantity of construction sand and mineral production1 was $7.96 billion. This was a 5.3% increase gravel increased by 1.2% and crushed stone increased by 5.9% from the State’s revised nonfuel mineral production value of from the previous year but remained significantly lower than $7.55 billion in 2013 (table 1). Nonfuel mineral production in prerecession quantities (table 1). the State surpassed $7 billion in value for the first time in 2007; it fell below that figure in 2009‒10 but has been above that Aggregates by State and End Use since 2011 (fig. 2). Arizona accounted for approximately 9.9% A companion dataset, “Aggregates by State and End Use,” of the total U.S. value in 2014, which ranked it first among the replaces the discrete aggregate tables that were included in 50 States, based on total value. On a per capita basis, the value of the individual State chapters prior to 2014 and is available nonfuel mineral production was $1,180 in 2014 compared to the on the State Minerals Statistics and Information web page at national average value of $252.

A land swap allowing the mine to proceed was passed by Congress in December 2014. When operational, it will be over 2,100 meters deep and produce 500,000 metric tons per year of copper (Resolution Copper, undated). • Florence Copper Co. was developing a mine near Florence, Pinal County, to extract copper using in situ means. In late 2014, Taseko Mines Ltd. acquired Curis Resources Ltd., the owner of the Florence project (Greve, 2014). • Mercator Minerals Ltd. filed for bankruptcy in December 2014 (Supreme Court of British Columbia, 2014).

1The terms “nonfuel mineral production” and related “values” encompass variations in meaning, depending upon the mineral products. Production may be measured by mine shipments, mineral commodity sales, or marketable production (including consumption by producers) as is applicable to the individual mineral commodity. All USGS mineral production data published in this chapter are those available as of June 2017.
