The nation’s largest known lithium deposit is here in the Mountain West. As demand for electric vehicles grows — and with it demand for lithium, used to make EV batteries — one company hopes to harvest the mineral from that deposit in Northern Nevada.

In a park, nestled in a red rock canyon outside Moab, Utah -- a short drive from a giant pile of uranium tailings -- a crowd gathered for a celebration. Elected officials and community members mingled, and enjoyed refreshments. 

Volunteers placed pieces of yellow cake in small paper bowls.

A mining company says it won't carry out cleanup work ordered by the U.S. Environmental Protection Agency as part of a Superfund project in southwest Colorado.

The Durango Herald reported Wednesday that Sunnyside Gold Corp. sent the EPA a letter saying the company isn't responsible for pollution flowing from inactive mines in the area.

President Trump is touting his environmental achievements this week. But some environmental advocacy groups are not impressed. 

The Center for Western Priorities just released a new study that shows the administration has been almost unanimously approving de-regulatory policy changes requested or supported by mining and drilling groups. 

The Trump administration may soon push for more uranium mining in the Colorado Plateau, arguing the mineral is critical for national security. The potential move prompted criticism from Democrats during a hearing of the U.S. House Subcommittee on Energy and Mineral Resources on Tuesday. 

MILFORD, Utah — The San Francisco Mountains in southwestern Utah were once home to one of the richest silver mines in the world. When it comes to mining today, they stand mostly quiet — for now — with only a handful of rock mines operating in the area.

Every day, many millions of gallons of water loaded with arsenic, lead and other toxic metals flow from some of the most contaminated mining sites in the U.S. and into surrounding streams and ponds without being treated, The Associated Press has found.

That torrent is poisoning aquatic life and tainting drinking water sources in Montana, California, Colorado, Oklahoma and at least five other states.

Starting this fall, our region will host something new: a graduate program in space resources.

“This is the very first program in the world that is focused on space resources,” says Angel Abbud-Madrid, the director of the Center for Space Resources at the Colorado School of Mines.

A U.S. district court judge has struck down the City of Oakland’s ban on transporting coal through a planned export terminal there.

One year ago — on Aug. 5, 2015 — an EPA crew at the Gold King Mine in southwest Colorado accidentally unleashed 3 million gallons of orange water filled with mercury and arsenic.

The toxic spill flowed into the Animas River, eventually running into New Mexico's San Juan River and into Lake Powell. So far, disaster response and water quality monitoring have cost the EPA about $29 million — and the problem isn't over yet.
