Directory of Arizona's Active Mines-2020
AZGS' Open-File Report 'Directory of Active Mines in Arizona: 2020' documents 401 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.
Of these 401 active mines/projects, 272 are aggregate facilities that include things such as sand and gravel. The second largest category is that of building stone, with 69 sites, and includes products such as decorative stone and dimension stone. The third is metallic mines/development projects, with 24 sites. The remaining categories (e.g., gypsum, cinders, uranium) account for only ~9% of all active mine sites.
2019 Mineral Production. Arizona's production of non-fuel mineral commodities yielded $6.970 billion dollars accounting for 8.08% production in the U.S. Only Nevada was more productive with $8,190 billion accounting for 9.49% of US production. Values for 2020 mineral production should be forthcoming from the US Geological Survey in the 1st quarter of 2021.
