In spring 2015, the Arizona Geological Survey Mining Data site launched the Colvocoresses collection, comprising reports on field visits or submitted reports from approximately 300 Arizona mine and mining properties by Mr. Colvocoresses or his associates.
On July 2, 2014, the James Doyle Sell collection, which include more than 800 Arizona mine file records, was added to the Arizona Geological Survey Mine Site.
In April, the Arizona Geological Survey (AZGS) launched a new digital collection of Arizona’s mining history.
From alabaster to zinc, this is the earliest volume of Arizona minerals and rocks published by the Arizona State Bureau of Mines. Rough locations are provided for each entry. The first formal publication of an Arizona Geological Survey predecessor agency began in 1915 while Charles Willis was director.
The decade-long rise in the price of gold from less than $400 per troy ounce to over $1,600 has resulted in the renewal of gold mining and increased exploration activity in Arizona. Lode properties are receiving the most significant activity due to their large number of contained ounces of gold. A few, small placer properties are also being sampled or operated on a limited scale.
The value of Arizona's non-fuel mineral production totaled $6.7 billion in 2010 according to preliminary USGS figures. This was 10.5% of the United States' total, making Arizona the number two producer in the nation. Principal commodities mined were copper, molybdenum, sand and gravel, cement and crushed stone. In addition, Arizona coal production added another $273 million bringing the total mined value to nearly $7 billion.
