Global miners are deploying a raft of new leaching technologies that can extract low concentrations of copper from waste rock and help avoid lengthy mine permitting delays.

Located below the Naica Mine, the cave produces jaw-dropping crystals that dwarf humans who enter the area. Containing selenite—gypsum—crystals measuring up to 39 feet (12 meters) in length, the cave is a relatively hostile environment—without proper protection, people would only survive about 10 minutes inside.

In Apache County, the Cane Valley Mining District, mines surrounding the Perilla Mountains and Ramsey Canyon offer promising prospects. Gila County boasts the Globe-Miami Mining District, renowned for its frequent discovery of fascinating specimens. Selenite can be found here at Sleeping Beauty Peak, Lost Gulch Mine, or the Coronado …
