Scientists at the Arizona Geological Survey (AZGS), University of Arizona, Northern Arizona University (NAU), and Arizona State University (ASU) have been awarded ~$1 million from the United States Department of Energy (DOE) to characterize rock resources for permanent CO2 sequestration and build a model that will advance the commercialization of CO2 sequestration at the community scale in Arizona.
AZGS' Open-File Report 'Directory of Active Mines in Arizona: FY2021' documents 433 active, full-time mines or development projects in the state of Arizona. Mines come in all shapes and sizes, from small sand and gravel operations providing materials for local road maintenance and construction to the large open-pit copper mines, such as Morenci and Ray.
There were 401 active, full-time mines or development projects operating in the state of Arizona in 2020.

America’s infrastructure is built of sand, gravel, and crushed rock; collectively referred to as aggregate. And that is the topic of our 45th episode of the Arizona Mining Review - an interview with Eric Mears on gravel production and consumption in the Phoenix Metro area.
