May 13, 2026 –The leading opposition group to the Copper World mine in the Santa Rita Mountains has filed two lawsuits seeking to overturn a recent State Land Department sale of 160 acres to be used for storage and disposal of mine tailings.
The sale, at public auction on April 29, is seen by Copper World developer Hudbay Minerals Inc. as a way to add a “buffer” area between the mining company’s lands in the Santa Ritas and a major subdivision lying to its north, known as Corona de Tucson. Opponents, however, said the sale will enlarge the scale of Hudbay’s mining operation at Copper World and help it dispose of more tailings on more land.
