An Australian company has launched a rare earths mining project just outside Joshua Tree National Park in critical desert tortoise habitat, an area the company’s director refers to as an “emerging heavy rare earth district.”

The company, Dateline Resources Ltd., says that historical sampling of the area in the Pinto Mountains south of Twentynine Palms found enrichment in elements key to powering electric vehicles, wind turbines and defense systems.

The United States depends heavily on China for its supply of these critical minerals, a major national security vulnerability the Trump administration has sought to address through a series of regulatory changes and financial incentives aimed at shoring up domestic production.

The project is in its early stages, and it’s unclear whether further testing will confirm the presence of rare earth elements across a broad enough area to warrant extracting them. The site is roughly 100 miles southwest of the nation’s only fully functional rare earths mine — Mountain Pass operated by MP Materials, in which the U.S. Department of Defense holds a 15% stake.

It’s also steps from Joshua Tree National Park, one of the nation’s most beloved desert getaways where about 3 million people visit annually. The 1,200-square-mile park and the public lands that surround it are home to sensitive plants and wildlife that environmentalists say would be harmed by a major mining project that could deplete water supplies, draw traffic and generate toxic waste.

“This is truly one of the most iconic landscapes in America,” said Chance Wilcox, California desert program manager for the National Parks Conservation Assn., as he stood atop a rocky slope within the project footprint on Friday.

Beside him, a wooden stake marked the corner of a mining claim. About 100 feet away, a metal post denoted the park’s boundary. In the valley below sat the fee booth for the east entrance.

If mining were to go ahead here, visitors would likely be able to see the activity while driving into the park, Wilcox pointed out. “It just emphasizes this company’s blatant disregard for our nation’s crown jewels,” he said.

Dateline did not return messages seeking comment on the project. The company also operates the Colosseum Mine in the nearby Mojave National Preserve, which the Trump administration has touted as pivotal to its efforts to develop a homegrown critical minerals supply chain.

Dateline first announced the venture — the Music Valley heavy rare earths project — late last month, saying it had acquired 57 claims totaling 1,140 acres and had also invested $1 million in Fermi Critical Minerals Inc., an American company that holds uranium and rare-earths projects in multiple western states. Dateline later broadened the footprint by staking an additional 969 claims covering 19,380 acres, a subsequent release states.

The company now holds claims over a roughly 32-square-mile area, the vast majority within the Bureau of Land Management’s jurisdiction.

U.S. Geological Survey geologists first identified rare earth mineralization in the Music Valley area in 1954, with sampling reporting enrichment in dysprosium, terbium, yttrium and ytterbium, Dateline Resources said in a press release. The company is now training modern exploration techniques on outcroppings of a 1.8-billion-year-old type of metamorphic rock called Pinto gneiss.

While rare earths will be the primary focus, exploration will also assess the potential for gold mining — the area is dotted with old, small-scale adits and shafts.

The project is located in what’s known as an area of critical environmental concern. The U.S. Fish and Wildlife Service has deemed the sweeping landscape to be crucial to the survival of the Mojave desert tortoise, which is endangered in California thanks to a stew of threats including development, disease, raven predation and climate change.

The land abutting the Pinto Mountains Wilderness is also home to badgers, bighorn sheep and Mojave fringe-toed lizards. Massive yuccas and barrel cacti stud its steep slopes.

On Friday, desert iguanas and whiptails scampered across an access road, portions of which wind through the national park. A chuckwalla sunned itself on a boulder. Nearby, a desert tortoise had emerged from its burrow to munch on some grass — a rare sight that elicited a whoop of joy from Wilcox. “This is a really special place,” he said.

If the area proves to be a valuable source of heavy rare earth elements, it would be significant as the U.S. has none, said Daniel O’Connor, co-founder and chief executive of Rare Earth Exchanges, a website that covers the global rare earths market. Mountain Pass primarily produces light rare earth elements, which are typically more abundant.

“Our entire war machinery — missiles, radar, fighter jets — all need these heavy rare earths,” O’Connor said.

Still, he said, even if the U.S. were to start producing heavy rare earths, the country would likely remain reliant on China to process them — a complex, multi-stage undertaking that involves chemically separating the elements from ore. Companies controlled by the Chinese treasury currently separate and refine an estimated 90% of the world’s supply of rare earth elements, and about 90% of the specialized magnets they are used to create are also manufactured in China, he said.

O’Connor described the Music Valley project as early-stage and speculative, pointing to a mining tradition dating back to the Wild West in which prospectors tout samples that show heavy concentrations of minerals in a bid to loosen investors’ wallets. There’s no way to know how widespread or systematic those concentrations are without technical reports disclosing a project’s mineral contents and quality, he said. Dateline does not yet appear to have released any such report, which are industry standard, he said.

Rare earths mining typically involves pulling out ore with jackhammers or dynamite and grinding it down before chemically treating it — processes that consume a lot of energy, generate toxic waste and can unleash radiation that’s often present in the ore, he said.

“It’s hard to think of a worse place for a massive industrial project than sensitive desert tortoise habitat on the very edge of Joshua Tree National Park,” wrote Brendan Cummings, conservation director for the Center for Biological Diversity, in an email.

A buildout of the claims could end public access to the area and permanently scar the landscape, drawing traffic and light pollution and harming springs and groundwater stores, he said. Given those potential impacts, he is skeptical that the developers could lawfully be granted the necessary federal, state, and local approvals to proceed.

Conservationists also point to Dateline’s history operating the Colosseum Mine as a source of concern, saying the company flouted National Park Service rules and damaged the surrounding landscape.

“They don’t respect public lands, national parks or the law, so there’s every reason to be deeply concerned about this proposal,” said Rep. Jared Huffman (D-San Rafael), the ranking member on the House natural resource committee who said the project “has red flags waving in every way.”

“We do need domestic and critical minerals sourced from friendly countries and responsible actors,” he added, “but it doesn’t mean we need them everywhere or at any cost.”

Nearly a year after the Los Angeles Zoo shipped off Billy and Tina to Oklahoma, animal rights activists have kept up the call to move the elephants to a sanctuary. Recently, actor Samuel L. Jackson joined their roster of supporters.

In the dead of night last May, the pair of Asian elephants were shuttled via shipping containers to the Tulsa Zoo, where their L.A. keepers said they’d join a herd large enough for the social animals’ well-being — something the L.A. Zoo could not provide.

But animal welfare groups say the pachyderms are not better off in their new home, citing concerns about their physical and mental health.

Tina, 59, is battling a uterine infection and Billy, 40, could face invasive sperm extractions, according to Courtney Scott, veteran elephant consultant with In Defense of Animals.

The pair were already showing “very chronic stress behavior” in L.A., Scott said, such as head bobbing, swaying and pacing. In Tulsa, “that seemed to intensify.”

How do they know? A volunteer from the Elephant Guardians of Los Angeles visited twice and chronicled their condition with photos and videos, she said.

Scott’s group ranked the Tulsa Zoo among the 10 worst zoos for elephants last year, claiming it suffers from overcrowding and a breeding program with a checkered history.

Jackson, of “Pulp Fiction” and Marvel fame, said sanctuaries are willing to take in Tina and Billy. “Continued exploitation and denial of their freedom is making them worse, and time is running out!” Jackson said in a statement provided by In Defense of Animals.

Jackson is just the latest star to chime in. Cher, Lily Tomlin and the late Bob Barker have previously advocated for Billy, who arrived at the L.A. Zoo in 1989.

At the Tulsa Zoo, which did not respond to requests for comment, Billy and Tina are now part of a crew that includes five other Asian elephants. The zoo’s elephant complex spans 17 acres and includes a wooded preserve not open to public viewing as well as a 36,650-square-foot barn.

This month, the zoo announced Tina was suffering from an infection and abnormal buildup of fluid in her uterus. A statement describes it as a side effect of reproductive tract disease, which she had a history of before arriving at the zoo and is common in aging female elephants.

“There are very limited options beyond antibiotics and, unfortunately, antibiotics alone will not fully resolve the infection,” the zoo said. “That reality is difficult to share, but it’s important to be transparent that this condition has the potential to become life-threatening.”

Tina isn’t showing signs of discomfort and remains “bright and engaged” and “greets her keepers,” according to the zoo.

Billy and Tina have lived together for more than 15 years and share a strong bond, according to the L.A. Zoo. They communicate by touching each other with their trunks, smelling each other and vocalizing.

Billy hails from a herd in Malaysia that was culled to clear land for palm and rubber plantations, according to the zoo. He arrived in L.A. at the age of 4 as part of an effort by the Malaysian government to relocate young elephants to zoos in the late 1980s.

In 2009, Tina landed at the San Diego Zoo for rehabilitation after being confiscated from a private owner. She was moved to the L.A. Zoo the following year.

For years, animal welfare advocates and some politicians tried to compel the L.A. Zoo to relocate the elephants to somewhere more spacious and which, according to them, would offer a better quality of life.

The L.A. Zoo, however, has long defended the care provided to its elephants and did not cite health reasons for Billy’s and Tina’s relocation in 2025.

According to an online FAQ, that decision stemmed from the death of two older herd members — Jewel and Shaunzi — who were euthanized in 2023 and 2024, respectively, for age-related health reasons. Without them, the zoo no longer met Assn. of Zoos and Aquariums standards requiring accredited zoos to have at least three Asian elephants.

The zoo said it wasn’t possible to bring in more elephants, so it made the “difficult decision” to relocate Billy and Tina, according to a statement from last year.

“The care and well-being of the animals is always a top priority and decisions impacting the animals are made at discretion of the Zoo Director — an authority granted in the Los Angeles City Charter,” the statement said. “Activist agendas and protests are rightfully not a consideration in decisions that impact animal care.”

The zoo said it spoke to sanctuaries accredited by the Assn. of Zoos and Aquariums when weighing what to do with the elephants, but elephant experts from around the country recommended Tulsa Zoo as the best fit for the pair. Criteria included space, facilities, staff expertise and herd dynamics.

Denise Verret, director of the L.A. Zoo, noted at an L.A. City Council budget hearing last year that the Toronto Zoo lost its accreditation in 2012 by sending its elephants to a sanctuary at the direction of the Toronto City Council.

L.A. City Councilmember Bob Blumenfield, a longtime advocate for the elephants, filed a motion seeking to pause their relocation until the City Council could review the possibility of sending them to a sanctuary. An L.A. resident filed a lawsuit over the zoo’s decision and sought to halt the elephants’ transfer. Neither effort was successful, but activists haven’t given up.

Sanctuaries in Georgia and Cambodia have agreed to take in Billy and Tina, according to Scott. Another, the Performing Animal Welfare Society in Northern California, has said it would accept Billy and, likely, Tina, she said.

“It would just be a matter of sitting down,” she said, “and figuring out the best one for the elephants.”

A lunar telescope could be installed in a crater on the far side of the moon.

Over the past century, the Earth has become a noisy place for astronomers wishing to listen to the radio waves that fill the universe. Those waves emanate from glowing gas clouds of hydrogen, auroras of distant planets and fast-spinning neutron stars. But those signals are often drowned out by ubiquitous transmissions of modern society like radio and television shows, cellphone calls and industrial electrical equipment.

The Earth’s ionosphere also blocks long-wavelength radio waves, which would give clues about the very early universe, from reaching ground-based radio telescopes. But on the far side of the moon, all that radio noise from Earth is silenced, unable to pass through 2,000 miles of rock. And the long-wavelength radio waves could also be observed.

Building a radio telescope in a crater on the moon would take advantage of that natural concave shape. A location near the equator in the middle of the far side could be an ideal listening spot.

After years of talking about lunar outposts in vague terms for sometime in the indefinite future, NASA recently shifted, putting a continuing U.S. presence on the moon solidly on its road map for the coming decade.

Plans for a moon base would proceed in phases. It would go from regular moon visits to building permanent infrastructure; power and communication systems; vehicles to carry astronauts and cargo across the surface; and possibly nuclear power plants.
