For years, low prices and a glut in global markets have forced U.S. uranium producers to sit on the sidelines.

But the war in Ukraine has led to higher prices, and the industry’s push to create a government subsidy for domestic uranium could be gaining traction.

Conservationists fear that Energy Fuels, the company that owns a handful of claims near the Grand Canyon, could ramp up development.

Amber Reimondo is with the Grand Canyon Trust.

“Uranium prices have blown up. Especially since the war in Ukraine started," Reimondo said. "For the last 30 years, it’s been pretty regularly in the $20 to $30 per pound range. And right now it’s upwards of $55 to $60 a pound.”

She says that active mines could contaminate groundwater for tribal communities in the region.
