PHOENIX - Tupac Acosta pounded on a drum as he and a handful of others tried to grab the attention of motorists headed down Camelback Road in Phoenix late Friday morning.
Their goal: Bring attention to a federal land exchange they say endangers an area sacred to the San Carlos Apache tribe.
"Today's action is an act of solidarity, a protest against the inclusion of Oak Flat in the National Defense Authorization Act that was passed in December," Acosta said.
People from Tonatierra, an indigenous people's organization, held up signs outside of Sen. John McCain's office. McCain led the efforts to approve the land exchange with Resolution Copper Mining, which plans to break ground on a $61.4 billion mining operation in southeastern Arizona by mid-2020, according to its website.
In a statement, McCain said the mine would generate an estimated 1,400 jobs and would have an economic impact of about $61.4 billion over its operational lifetime.
Officials with Resolution Copper did not return calls seeking comment.
Acosta said the legislation, tucked into a defense-spending bill, was underhanded and called it a "travesty."
"It was put into that package without our consent, without our knowledge," Acosta said. "We denounce, deny and do not consent to that. We call upon all people with good conscious to stand up for the human rights of the Apaches."
The group held Friday's protest in conjunction with a 44-mile march by others who oppose the mine. Marchers left from the San Carlos Apache Tribe's administration office Feb. 5 and planned on arriving to the Oak Flat campground Feb. 6 in the afternoon.
Some participants plan ned on occupying the area for however long it takes, said Vernelda Grant, an organizer of the march.
Organizers said there were planned protests in Tucson and Sedona as well.
Protesters have said the environmental impacts the mine will have on water and air quality have concerned them.
"These projects end up impacting and destroying our relationship with the natural world," Acosta said. "We are killing Mother Earth. We have to stop. We have to stop now. We can stop at Oak Flat."
