The old Magma Mine started producing in 1912 and soon became one of the largest copper producers in the United States. The operation shut down in 1996, but the potential to develop a rich new copper deposit near the town of Superior and reusing the already disturbed historic mining site kept the site active and alive.

Many icons of the once bustling West Plant site have survived, but fell into disuse or were demolished for safety reasons. In 2011, Resolution documented the surviving buildings and facilities to decide whether to restore, demolish or reuse them. Multiple technical studies have been conducted on the Smelter structures in particular in recent years. Based on the results of these studies, the company has validated and confirmed that a proactive approach is required to clean contaminants out of the soil and eliminate a safety threat to our employees posed by the unstable Smelter structures. Due to the threat of collapse and falling debris, restoration work is not an option for the Smelter complex.
