Sustainable Development


In Miami, we are reclaiming approximately 1,000 acres through various projects. One such project includes the removal of more than 8.2 million cubic yards of material from historic stockpiles to other areas of the mine in order to reshape and revegetate areas closer to town.


The Webster Lake project at Miami uses reclamation to significantly reduce the amount of mine impacted water that must be managed by the site. The benefit coincides with the restoration of a stream channel capable of conveying unimpacted stormwater runoff from the reclamation areas off site. This natural drainage has not been “free draining” since the 1930s, making it a significant step for Miami reclamation and one of the largest reclamation projects conducted by Freeport-McMoRan. The designs utilize shallower slope angles and more controlled stormwater runoff, in a variation of the Bisbee tailings dam reclamation design. The unimpacted runoff will be directed off-site to help remediate the Bloody Tanks and Pinal Creek stream channels.

Miami has a rich and diverse history in mining, ranching and western heritage. Through Freeport-McMoRan’s support, the Bullion Plaza Cultural Center & Museum, a historic school building from 1923, will help maintain the area’s rich history. The museum has received funding to support restoration activities to help sustain public use, as well as develop a community archive and research center.  The archiving process includes digitizing microfilm records of the Arizona Silverbelt newspaper from the late 1870s to the present and digitizing many of the documents and pictures pertinent to the settlement of the Globe-Miami mining district.  The research facility will provide educational, cultural preservation and economic development opportunities for the Globe-Miami community. The museum will also collaborate with the Gila County Library System to provide a foundation for resource integration, historical resource sharing and referrals through the technology obtained with our support.
