Ray Copper Mine

The Ray copper mine is located near Kearny in eastern Pinal County.

PRESCOTT — Officials last week marked the completion of a long-awaited federal land exchange that will allow for the expansion of an eastern Pinal County copper mine while adding to wilderness in three Arizona counties.

The land exchange involving nearly 18,000 acres, including more than 600 acres near Casa Grande, was 26 years in the making, officials said.

At the Yavapai County Courthouse Friday, Secretary of the Interior David L. Bernhardt was joined by U.S. Rep. Paul Gosar, R-Prescott, Bureau of Land Management Arizona Director Ray Suazo and other public and private representatives to announce the transfer of lands between the BLM and the private company ASARCO through the Ray Land Exchange. This was the final step in the process that will also add riparian habitat and established wilderness areas in Pinal, Gila and Mohave counties.

“This action allows for the hundreds of mining jobs to continue to produce American-made minerals — reducing our dependence on foreign producers — while also enhancing recreational and hunting access on public lands in the West,” Bernhardt said in a statement.

Suazo said the land exchange balances the public’s need for hunting and recreation access with the mining company’s need to continue responsible mineral development and Arizona’s need for continued economic viability.

“This administrative land exchange, which began 26 years ago, is a prime example of an equitable exchange that provides many benefits to the public,” said ASARCO Vice President and CFO Oscar Gonzalez Barron in a press release.

Even though many environmentalists opposed the land exchange, citing the Ray Mine’s poor environmental record in the past, officials said the “majority of input received during the comment period strongly supported this land exchange.”

The BLM issued two patents transferring 9,339 acres of public land adjacent to ASARCO’s Ray Mine Complex and Copper Butte properties for mine expansion. This includes 7,196 acres of full estate and 2,143 acres of subsurface mineral estate, the surface of which is already owned by ASARCO.

In exchange, the BLM acquired 7,298 acres of ASARCO-owned land in Pinal and Mohave counties through a general land deed, consolidating checkerboard land ownership in those areas, allowing better management of wildlife migration corridors and improving access to existing public lands for hunting and other family recreation.

Federal law requires that the lands exchanged be equal in value, with no more than a 25% cash equalization payment included. In addition, ASARCO spent over $15 million to finalize the land exchange, $12 million of which was directed to the BLM and BLM-required third-party contractors.

Ultimately, it took 26 years to complete the Ray Land Exchange. During that time, litigation from environmental groups and a 10-year National Environmental Policy Act process delayed the exchange.

The Trump administration has sought to streamline NEPA reviews. President Donald Trump issued an executive order “establishing Discipline and Accountability in the Environmental Review and Permitting Process for Infrastructure Projects.”

The order requires that environmental impact statement documents be completed in one year and in less than 150 pages with exceptions for those that are unusually complex or in coordination with other federal agencies.

A Notice of Decision was published on Nov. 4 initiating a 45-day protest period for the land exchange. The BLM received and resolved three protests. The documents, maps and other information about the approved land exchange are available online at https://go.usa.gov/xEnKR.
