Mining

An Australian company staked a massive lithium claim on the desert playa only to later find the land is off limits to mining.

At least three companies have staked mining claims in some of the best remaining sage grouse habitat in Oregon.

The company exploring an Oregon lithium deposit is encouraged by efforts to bolster the U.S. critical minerals supply chain, but a mining pitch is still years away.

Oregon’s senior senator says the U.S. needs to source, refine and recycle more critical minerals like lithium domestically as the nation transitions off fossil fuels.

A supervolcano, a massive eruption and a lost lake left Oregon with what could be the largest known lithium deposit in the United States.

The project in southern Malheur County could eventually help supply a growing U.S. appetite for domestic lithium used to make batteries.

A Nevada rancher suing to block construction of the largest lithium mine in the U.S. says the government’s environmental assessment of the project relies on a baseline set by a consultant for the mining company with a conflict of interest.

Tribal lawyers are asking a U.S. judge in Nevada to reconsider her earlier refusal to block digging at a proposed lithium mine near the Oregon line.

An explosives manufacturing company pleaded guilty in U.S. District Court Friday for failing to notify authorities of the release of 13,000 pounds of ammonia into the air at its St. Helens plant.

Coal mining could be coming back in the Northwest to an old coal mine in southeast King County.
