Arizona Geology E-Magazine: Directory of Arizona's Active Mines
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.
Of these 433 active mines/projects, 294 are aggregate facilities that include products such as sand and gravel. The second largest category is that of building stone, with 67 sites, and includes products such as decorative stone and flag stone. The third is metallic mines/development projects, with 27 sites. The remaining categories (e.g., gypsum, cinders, uranium) account for only ~10% of all active mine sites.
