RENO, Nevada (AP) 鈥 The Biden administration says it has completed a court-ordered review that should ensure construction continues at a Nevada lithium mine, despite legal challenges brought by conservationists and tribal leaders.
At the same time, in a broader response to that more strictly interpret a Civil War-era mining law, the Interior Department announced Tuesday it is taking steps to clarify mineral rights under the 1872 law to reflect the 鈥渞ealities of the 21st century.鈥
The moves come after the 9th U.S. Circuit Court of Appeals blocked a proposed copper mine in Arizona last year. The Appeals Court is considering a related appeal filed by environmentalists and Native American tribes challenging construction of the huge Thacker Pass lithium mine in Nevada near the Oregon line.
Lithium is a key element needed to manufacture batteries for electric vehicles 鈥 a centerpiece of President Joe Biden's 鈥渃lean energy鈥 agenda intended to expedite a transition from fossil fuels to renewable forms of energy.
The 9th Circuit's so-called 鈥淩osemont decision鈥 upended the government鈥檚 long-held position that the 1872 Mining Law conveys the same rights established through a valid mining claim to adjacent land for the disposal of tailings and other waste. The 9th Circuit held instead that the company must establish 鈥 and the government must validate 鈥 that valuable minerals are present under such lands for a claim to exist.
in a ruling in February that found the U.S. Bureau of Land Management failed to comply with the law when it approved a Canadian company's plan to open the Thacker Pass mine about 200 miles (322 kilometers) northeast of Reno.
Despite that ruling 鈥 and over the objections of environmentalists and tribes who now are appealing to the 9th Circuit 鈥 Du allowed construction to begin at the mine while the agency provides additional proof the company has the mineral rights necessary to dump waste rock and tailings from the operation on adjacent federal land.
Interior Department officials announced Tuesday that the land management bureau has completed the review necessary to establish mineral rights on the land adjacent to Lithium Americas' project and is convinced it will satisfy Du鈥檚 requirement.
have been staging a protest since last week near the site where the open pit mine is planned. The mine would ultimately be deeper than the length of a football field. They say federal law prohibits construction of the project near where dozens of Paiute tribal members were massacred by the U.S. cavalry in 1865.
The San Francisco-based 9th Circuit has scheduled oral arguments for the for June 26 in Pasadena, California.
Lithium Americas CEO Jonathan Evans said in a statement after Tuesday's announcement they are 鈥減leased the administration has established a path forward that allows us to resolve the outstanding matters related to the approval of our Thacker Pass project."
Sen. Catherine Cortez Masto, D-Nev., called the 鈥淩osemont decision鈥 misguided and said it defies more than a century of practice on landscapes in the West. She recently seeking to insulate the mine at Thacker Pass and others from the ruling by essentially adopting language that reverts to the historic interpretation that automatically conveyed established mining rights to the neighboring lands.
An Interior Department official told The Associated Press ahead of Tuesday's formal announcement that the Biden administration doesn鈥檛 intend to challenge or appeal the Rosemont decision. The official requested anonymity because they were not authorized to discuss the issue publicly. The department issued a new legal opinion from its solicitor general to provide guidance to mining companies.
The new opinion 鈥渨ill support the timely review of mining proposals on federal lands and is one step of many" Interior is taking to 鈥渦pdate guidance for mining companies to reflect the realities of the 21st century,鈥 Deputy Interior Secretary Tommy Beaudreau said in a statement.
Beaudreau is the chairman of the administration's Working Group on Mining Regulations, Laws and Permitting that's expected to offer a list of recommendations sometime this year to make improvements to the antiquated mining law.
Dozens of other mines face similar situations as Thacker Pass, an Interior Department official said Tuesday.
鈥淲e are not appealing or challenging Rosemont," a spokesman said. 鈥淚t makes it clear for the company that if you have a situation like Rosemont or Thacker, you have these options."
Officials analyzed more than 100 of the nearly 500 individual claims and found only eight that don鈥檛 have evidence of enough mineralization to justify siting the waste rock dump there, Interior said.
Solicitor General Robert T. Anderson said in his 10-page opinion that the U.S. Bureau of Land Management should not approve a mine operating plan if the record lacks any evidence of valuable mineral deposits on the adjacent land planned for the waste rock dump. But he said the agency is not required to 鈥渃onduct a validity determination ... if there is some evidence of discovery.鈥
