The land grab was sneakily anti-democratic even by congressional standards. For more than a decade, the parcel containing Oak Flat has been coveted by Rio Tinto, Resolution’s parent company — which already mines on its own private land in the surrounding area — for the high-value ores beneath it.

The swap — which will trade 5,300 acres of private parcels owned by the company to the Forest Service and give 2,400 acres including Oak Flat to Resolution so that it can mine the land without oversight — had been attempted multiple times by Arizona members of Congress on behalf of the company. (Among those involved was Rick Renzi, a former Republican representative who was sent to federal prison in February for three years for corruption related to earlier versions of the land-transfer deal.) It always failed in Congress because of lack of support. But this time was different. This time, the giveaway language was slipped onto the defense bill by Senators John McCain and Jeff Flake of Arizona at the 11th hour. The tactic was successful only because, like most last-minute riders, it bypassed public scrutiny.

It’s worth noting that Rio Tinto affiliates have been McCain campaign contributors, and that Mr. Flake, before he made it to Congress, was a paid lobbyist for Rio Tinto Rössing Uranium (a huge uranium mine in Namibia). Mr. McCain and others assert that the mining project will be a boost to the local economy, though it’s unclear how many of the 1,400 promised jobs would be local; a Superior-area miners’ group, in fact, opposes the swap on the basis that it won’t help the local people or economy. Rio Tinto, incidentally, has been called out in the past for environmental devastation.

“Why is this place sacred?” said Wendsler Nosie Sr., a former chairman of the San Carlos Apache, in a recent interview with Cronkite News. “No difference to Mount Sinai. How the holy spirit came to be.” If you don’t want to take his word for it, the archaeological record at Oak Flat contains abundant evidence that the Apache have been here “since well before recorded history,” according to congressional testimony by the Society for American Archaeology.

If Oak Flat were a Christian holy site, or for that matter Jewish or Muslim, no senator who wished to remain in office would dare to sneak a backdoor deal for its destruction into a spending bill — no matter what mining-company profits or jobs might result. But this is Indian religion. Clearly the Arizona congressional delegation isn’t afraid of a couple of million conquered natives.
