DOE awards first contracts for supply of uranium for strategic uranium reserve:
On Dec. 15, 2022, U.S. Department of Energy (DOE) notified the first successful suppliers on the awards for U.S. origin uranium for its strategic uranium reserve. DOE was seeking up to an estimated one million pounds of U3O8 [384.6 t U], produced at a domestic uranium recovery facility and already in storage at the Honeywell Metropolis Works uranium conversion facility located in Metropolis, Illinois.

Interestingly, only the company with the smallest award is based in the U.S. (enCore Energy Corp.), while the others are based in Canada (Energy Fuels Inc., Uranium Energy Corp.) and in Australia (Peninsula Energy Limited). And, it is the U.S.-based company that received the highest premium by far on the spot price, if our guesses are correct.
At spot prices, the cost of the total amount awarded would be $47.84 million, so the estimated total premium awarded is $14.06 million. Still, the estimated total of $61.9 million awarded utilizes only 82.5% of the $75 million appropriated by Congress for this year.

Six Democrats oppose Energy Department's proposed uranium reserve: A group of six Democrats is criticizing the Energy Department's proposed uranium reserve that could feed U.S. nuclear fuel and boost American mining.
The Biden administration has argued that creating a uranium reserve could bolster its clean energy goals since nuclear energy doesn't have any emissions. But in their Wednesday (Sep. 15) letter, the lawmakers warn of potentially adverse impacts on nearby communities and say there's not a need to increase U.S. extraction.
"The establishment of a government-funded uranium reserve poses a serious threat to the health of Tribal and environmental justice communities, as well as to the overall environment," said the letter, which was led by Sen. Ed Markey (D-Mass.) and Rep. Raúl Grijalva (D-Ariz.).
"Furthermore, there is no urgent need for domestic uranium. Instead of establishing a uranium reserve, the DOE should focus on the cleanup and remediation of existing toxic waste and conduct extensive outreach with communities affected by current and previous uranium mining operations," they added.

Congress approves appropriations of US$ 75 million for a uranium reserve for nuclear weapons activities: The Consolidated Appropriations Act, 2021 approved by both chambers of Congress on Dec. 21, 2020, includes appropriations of US$ 75 million for a uranium reserve for nuclear weapons activities - that is half of the amount shown in the president's budget proposal. The bill now goes to the White House for the president's signature to become law.

The act was signed into law by President Donald Trump on December 27, 2020.

President's budget proposes US$ 150 million for creation of uranium reserve in order to support struggling uranium mining companies: President Donald Trump's 2021 budget proposed $150 million for the creation of a U.S. uranium reserve as the administration seeks to help struggling producers of the fuel for nuclear power reactors. The money, if approved by Congress, would begin the process of purchasing uranium, Energy Secretary Dan Brouillette told reporters in a teleconference on the Energy Department's budget.

Uranium Energy Corp prefers to buy uranium on the spot market rather than mining it

On Mar. 16, 2021, Uranium Energy Corp announced that "we are establishing a physical uranium inventory initiative and have entered into initial agreements totaling $10.9 million to purchase 400,000 pounds of U.S. warehoused uranium [154 t U] at our account with the ConverDyn facility in Metropolis, Illinois.
This initiative will support three objectives: 1) bolsters our balance sheet as uranium prices appreciate; 2) provides strategic inventory to support future marketing efforts with utilities that could compliment production and accelerate cashflows; and 3) increases the availability of our Texas and Wyoming production capacity for emerging U.S. origin specific opportunities which may command premium pricing due to scarcity of domestic uranium."

On Mar. 17, 2021, Uranium Energy Corp further announced that it has secured 800,000 pounds of additional U.S. warehoused uranium [308 t U], consisting of 500,000 pounds for April delivery and 300,000 pounds for December delivery. Including the previously announced acquisition of 400,000 pounds, UEC has now entered into contracts to purchase a total of 1,200,000 pounds of U3O8 [462 t U] at a volume weighted average price of $28.94 per pound.

On Apr. 6, 2021, Uranium Energy Corp further announced that it has now secured an additional 705,000 pounds of U.S. warehoused uranium [271 t U], with delivery dates out to December 2022.
Including the previously announced contracts to acquire 1,400,000 pounds of uranium concentrates [538 t U], UEC has now entered into additional purchase contracts for a total of 2,105,000 pounds of U3O8 [810 t U] at a volume weighted average price of ~$30 per pound.

ADEQ issues revised draft Air Permit for Arizona 1 uranium mine:
The Arizona Department of Environmental Quality is still working on developing new, more environmentally protective air quality permits for three uranium mines in the Grand Canyon region.
The action comes after news broke late last year that elevated uranium levels had been measured in soils near Pinenut uranium mine, located 10 miles north of the Grand Canyon and owned by Energy Fuels Resources. In response, ADEQ decided to suspend its work on air quality permit renewals for all four uranium mines operated by Energy Fuels Resources.
ADEQ is now working to complete drafts of the new air quality permits for public review and comment. The revisions include faster execution of enhanced dust control measures if elevated uranium or radium levels are detected and extensive changes to the required soil sampling and radiation survey plan to mitigate potential impacts from high wind.
The state department will host public hearings on the new draft permits in Flagstaff, Tuba City and Fredonia, which it hopes to begin in early summer. (Arizona Daily Sun Apr. 15, 2016)

Mining at Arizona 1 mine to cease due to depletion of resources: Subject to the results of additional underground drilling, mining at the Arizona 1 mine is expected to cease in early FY-2014 due to the depletion of its known resources. (Energy Fuels Inc. Nov. 14, 2013)

Court dismisses appeal against reopening of Arizona 1 uranium mine: A federal appeals court has ruled against conservationists and tribes in their challenge of a uranium mine north of the Grand Canyon. The group had sued the U.S. Bureau of Land Management, alleging the agency relied on an outdated and inadequate environmental analysis in allowing the Arizona 1 Mine to resume operation. The 9th U.S. Circuit Court of Appeals ruled Monday (Feb. 4) that the BLM hasn't made any decisions that would trigger a new analysis and that the 1988 operation plan allows for temporary closures. (AP Feb. 3, 2013)

Appeal challenges Arizona 1 uranium mine threatening Grand Canyon: On Nov. 28, 2011, Conservation groups and American Indian tribes filed an appeal in the 9th Circuit Court challenging a lower court ruling that allowed a uranium mine near Grand Canyon National Park to re-open without updating decades-old environmental reviews. The Arizona 1 uranium mine is located near Kanab Creek immediately north of Grand Canyon National Park.
In 2010, conservation groups and tribes sued the Bureau of Land Management for failing to modernize 23-year-old mining plans and environmental reviews prior to allowing Denison Mines to resume uranium mining after the mine was shuttered in 1992. A federal judge in Phoenix this fall sided with the Bureau and the uranium industry saying no new plans or reviews were needed, prompting today's appeal.
The Arizona 1 is one of four existing uranium mines located in Grand Canyon's 1-million-acre watershed where the Obama administration has proposed a 20-year ban on new mining claims and uranium development on existing claims lacking valid existing rights. A final environmental impact statement was issued for the 1-million acre ban in October; a decision finalizing those protections could come as early as today. (Center for Biological Diversity Nov. 28, 2011)

Reopened Arizona 1 uranium mine largely left to regulate itself: Denison Mines began hauling ore out of the first and only uranium mine to reopen so far, 35 miles southwest of Fredonia, in December 2009. State environmental inspectors didn't arrive for a first inspection at the mine until it had already been open for about nine months. The Arizona Department of Environmental Quality (ADEQ) had unfilled requests for documents and inspections by engineers that it sought before the mine opened. Mine operators set to work without answering some of these requests.
The first inspection at the mine came in September, and ADEQ inspected at the ground level only, not traveling into the mine that reaches more than 1,252 feet below. Nevertheless, the inspection yielded what ADEQ deemed four "major violations."

"ADEQ is neither equipped nor inclined to regulate these mines in a way that even remotely ensures against irretrievable harm to the environment," said Taylor McKinnon, public lands campaigns director at the Center for Biological Diversity .
In the same month ADEQ inspectors arrived, federal inspectors concerned with worker safety cited Denison and contractors with air quality violations, failure to properly label power switches, equipment safety violations, lack of firefighting equipment inspections, and with another violation that is still being contested. One contractor was injured at the mine site in 2009. In all, the Mine Safety and Health Administration found 38 possible mine safety violations at the Arizona 1 Mine in 2010, many of which Denison is contesting. (Arizona Daily Sun Jan. 16, 2011)

Arizona 1 uranium mine operating illegally, EPA says: A uranium mine north of the Grand Canyon is operating in violation of the law, and its owner could face thousands of dollars in fines as a result, the U.S. Environmental Protection Agency said. The agency issued a notice of violation this week to Denison Mines Corp. for its Arizona 1 Mine, which is about 20 miles from the Grand Canyon's northern border. The EPA said Denison failed to notify the agency as to when it would resume mining and that it did not secure the necessary federal approval before ventilating the mine or testing emissions.
Denison President Ron Hochstein said Tuesday (May 4) that he was surprised by the notice and believed the company was operating within the law. He said he was working with regulators to address those issues. (AP May 5, 2010)

Environmental groups join tribes to protest Pinyon Plain uranium mine: Tribal leaders and conservationists came together Saturday (Aug. 24) to protest a mine extracting uranium south of the Grand Canyon. The Center for Biological Diversity estimated around 250 people attended the protest, which included members of the Havasupai and Lakota tribes. They're protesting Energy Fuel's Pinyon Plain Mine. (ABC15 Aug. 24, 2024)

Attorney General requests supplemental Environmental Impact Study for Pinyon Plain uranium mine: Arizona's attorney general has asked the Forest Service to update a nearly 40-year-old environmental review of a uranium mine on the Kaibab National Forest, saying there's new evidence of danger to regional water supplies.
In a letter Tuesday (Aug. 13) to forest supervisor Nicole Branton, state Attorney General Kris Mayes (D) said scientific advances in groundwater modeling "unequivocally show" that the Forest Service's past findings of no threat to water supplies from the Pinyon Plain mine were wrong.
In addition, Mayes said, a 2016 excavation mishap that's led the mine's operator, Energy Fuels Resources, to pump millions of gallons of water from the mine shaft suggests groundwater is closer to mining operations than believed when the Forest Service completed an environmental impact statement in 1986.
"Failure to supplement the EIS could result in devastating consequences for the region -- especially for vulnerable communities like the Havasupai Tribe," Mayes said. (E&E News Aug. 14, 2024)

Protest march against uranium ore hauling through Navajo Nation: Dozens of protestors, led by Navajo Nation President Buu Nygren, First Lady Jasmine Blackwater-Nygren and other leaders, marched on the northbound lanes of Highway 89 in Cameron on Fri, Aug. 2, 2024 against uranium hauling through the reservation. The highway was part of the route taken by trucks from the Pinyon Plain Mine near the South Rim of the Grand Canyon three days earlier when they began uranium ore transportation through a large swath of the nation.
Indigenous leaders and activists held protests over the weekend opposing the start of uranium ore transport from the state's only active uranium mine. (KNAU Aug. 4, 2024)

Governor, Energy Fuels agree to pause uranium ore transports through Navajo Nation: Arizona Governor Katie Hobbs and Energy Fuels have agreed to a pause the transporting uranium ore through the Navajo Nation. The ore was transported from the Pinyon Plain Mine in Tusayan to the White Mesa Uranium Mill in Blanding, Utah, near the southern Utah-Arizona border Tuesday (July 30). [...] Hobbs and Energy Fuels agreed to pause the shipments through Navajo lands, to give both Energy Fuels and the tribe an "opportunity to engage in good faith negotiations." (KAFF Aug. 1, 2024)

Navajo Nation President deploys police to stop unlawful uranium ore transport on tribal lands: The President of the Navajo Nation announced earlier today that he was sending police to stop the transport of uranium across tribal lands. In his statement, President Buu Nygren said that the shipment was being done illegally. He also stated the lack of notice from the mining company posed a danger to his people.
Energy Fuels Inc., the largest uranium provider in the United States, agreed to give the tribe notice before hauling uranium across exempted highways. According to Nygren, the tribe only found out about the shipment after trucks had departed.
Nygren dispatched tribal police to turn away the shipment. But, according to the Associated Press, the trucks left tribal lands before police could intercept them. (KSL July 31, 2024)

Interconnectivity of groundwater systems near Pinyon Plain/Canyon uranium mine poses risk to people, aquifers, and ecosystems, researchers find: A new research paper published recently in Annual Reviews of Earth and Planetary Sciences, coordinated by scientists from The University of New Mexico and collaborating institutions, addresses the complex nature and societal importance of Grand Canyon’s springs and groundwater. The paper, Hydrotectonics of Grand Canyon Groundwater , recommends sustainable groundwater management and uranium mining threats that require better monitoring and application of hydrotectonic concepts.
The data suggest an interconnectivity of the groundwater systems such that uranium mining and other contaminants pose risks to people, aquifers, and ecosystems. The conclusion based on multiple datasets is that groundwater systems involve significant mixing. (University of New Mexico Mar. 25, 2024)

County calls for more environmental monitoring for Pinyon Plain/Canyon uranium mine near Grand Canyon: The Coconino County Board of Supervisors has voiced their disapproval of this uranium mine in the past.

Rumble on the Mountain concert raises awareness toward threats of uranium mining at Pinyon Plain/Canyon mine to Indigenous communities: Musicians and activists joined forces on Feb. 3 for Rumble on the Mountain X , a benefit concert at the Orpheum Theater [in Flagstaff, AZ] that raised awareness toward mining threats facing Indigenous communities near the Grand Canyon.
The 10th Rumble centered around Pinyon Plain Mine, formerly Canyon Uranium Mine. On Jan. 8, Pinyon Plain extracted uranium ore seven miles from the South Rim of the Grand Canyon for the first time. Construction for the mine began in 1986 but was not fully completed until 2022.
The mine began production in January after increased international demand for nuclear energy following the 28th United Nations Conference of the Parties (COP28). However, the mining processes raise concerns from tribes located near it, particularly the Havasupai, about negative health effects and environmental harm.  (jackcentral.org Feb. 11, 2024)

USGS partners with Havasupai Tribe to identify potential contaminant exposure pathways from Grand Canyon uranium mining: A new USGS [U.S. Geological Survey] report, co-produced with the Havasupai Tribe, identifies exposure pathways posed by uranium mining in the Grand Canyon watershed that arise from traditional uses and cultural values placed on resources. Previous models did not take into account Tribal perspectives or traditional uses. [...]
Newly identified exposure pathways for the Havasupai include inhalation, ingestion and absorption from traditional food and medicines as well as ceremonial practices. Incorporating these exposure pathways into future research and risk analyses will lead to results that are more inclusive of Tribal resources and culture. (USGS Jan. 30, 2024)

Groups, scientists urge Arizona governor to close Pinyon Plain uranium mine in newly designated Grand Canyon National Monument: Echoing pleas from the Havasupai Tribe, Navajo Nation and other Tribes, scientists and Indigenous, faith, recreation and conservation organizations today called on Arizona Gov. Katie Hobbs to close the Pinyon Plain uranium mine, which is located in the country's newest national monument near the Grand Canyon. Closing the mine will safeguard Tribal cultural heritage and prevent permanent damage to the Grand Canyon's aquifers and springs.
The groups are calling on Gov. Hobbs to use her authority to rescind permits issued by the Arizona Department of Environmental Quality and instead issue new permits for closing and cleaning up the mine, also known as Canyon mine.
"This dangerous uranium mine should never have been approved, and we need Gov. Hobbs to fix this terrible mistake," said Taylor McKinnon, Southwest director for the Center for Biological Diversity . "The mining industry and regulators can't ensure that uranium mining won't permanently damage Grand Canyon's aquifers and springs. The governor needs to intervene before more irretrievable damage is done." (Center for Biological Diversity Jan. 29, 2024)

Navajo president warns of uranium ore transports from Pinyon Plain Mine through tribal lands: President Buu Nygren warned that the new Pinyon Plain Mine established just a few miles south of the national park will transport radioactive materials through Navajo communities.
The mine's owner, Energy Fuels, said it started mining uranium last month. It sits within the newly designated Baaj Nwaavjo I'itah Kukveni national monument and is operating because it was grandfathered in.
Nygren has warned that transporting uranium will occur through several Navajo communities in violation of tribal law. (KJZZ Jan. 15, 2024)

Tribes condemn start of uranium mining at Pinyon Plain Mine south of Grand Canyon: Two northern Arizona tribes this week condemned the start of operations at a uranium mine just south of the Grand Canyon.
The statements came after Canadian-based company Energy Fuels Inc. announced last month that operations at its Pinyon Plain Mine had commenced.
"It is with heavy hearts that we must acknowledge that our greatest fear has come true," a statement from the Havasupai Tribal Council read.
Meanwhile, Navajo Nation President Buu Nygren said in a statement that mining remains opposed "by all neighboring tribes that have forever called Grand Canyon their home." (Arizona Daily Sun Jan. 13, 2024)

Energy Fuels closes Pinenut mine for good, after increased uranium level found in soil nearby: [The Arizona Department of Environmental Quality] reported that Energy Fuels Resources has ceased operations at Pinenut mine and transported all uranium ore to milling operations in Utah. The company is therefore no longer seeking to renew its air quality permit for that location. Permanent closure of the Pinenut mine is a long-term process and will require working with multiple agencies. (Arizona Daily Sun Apr. 15, 2016)

Renewal process for air-pollution permit of three Grand Canyon mines suspended, as fourfold increased uranium level found in soil near Pinenut mine: State environmental officials have suspended the air-pollution permit renewal process for three uranium mines near the Grand Canyon. Recent tests showed uranium content in the soil near one of the mines is four times higher than previously measured. Arizona Public Radio's Ryan Heinsius reports. The tests were conducted in July and October outside the perimeter of the Pinenut Mine facility. The analysis showed uranium in the soil at one out of the five testing sites had spiked since 2011 when the mine reopened.
The Arizona Department of Environmental Quality says the elevated level of the radioactive metal doesn't present an immediate public health risk. But the agency has pushed the mines' owner, Energy Fuels Resources, to boost measures to control radioactive dust. ADEQ has also mandated that the company expand soil testing in the area.
ADEQ is considering the renewal of air-pollution permits for all three mines, but will suspend that process as it evaluates the company's new dust-control plan at the Pinenut Mine. The agency will eventually open a new public comment period and hold meetings for the permit renewals. (KNAU Arizona Public Radio Dec. 30, 2015)

Conservation groups urge BLM to suspend Pinenut uranium mine in response to groundwater contamination: Conservation groups have sent a letter urging federal regulators to suspend operations at a uranium mine near the Grand Canyon, where millions of gallons of uranium-laced groundwater threaten people and wildlife. Records from the U.S. Geological Survey show that the contaminated groundwater -- 80 times the limit set to protect public health and the environment -- have inundated the Pinenut uranium mine immediately north of Grand Canyon National Park. It is unknown whether deep aquifers and nearby springs in the national park are also being polluted.

By-product uranium production from phosphate in Louisiana to cease

By-product uranium production is to 'permanently' cease at IMC Global's Uncle Sam and Faustina facilities in Louisiana. Low uranium prices are cited as the major reason for the decision by senior management. The facilities' combined production of 950 000 lbs U3O8 (365.4 tU) last year accounted for approximately 16% of uranium produced in the US; 1998 production is expected to be similar. Meanwhile IMC's New Wales and Plant City recovery facilities in Florida have remained on 'stand-by' since 1992. (UI News Briefing 98.49, Dec. 9, 1998)

Sharp rise of uranium value in monitoring well necessitates changes in groundwater restoration regime at Mine Unit 3 of Crow Butte in situ leach uranium mine

"While ensuring stability trends in MU3 [Mine Unit 3], well P246 (WH7 MU3) exceeded the restoration value for uranium. The value for uranium went from .09 [mg/L] (9/26/14) to 4.04 [mg/L] (3/29/17). Based on a discussion with Nebraska Department of Environmental Quality (NDEQ), MU3 was returned to IX/RO treatment on September 15, 2017 in order to spot treat the well. Spot treatment is currently ongoing in contrast to the requested alternate decommissioning schedule which lists MU3 as in stability monitoring. It is likely that mining solution from MU7 migrated into the area and impacted the water quality in P246. In addition to resuming restoration activities around the well, CBO has implemented a monitoring program around MU2 and MU3 in order to prevent a similar event." [emphasis added]

NRC Board rules that tribe's unwillingness to cooperate on identification of Traditional Cultural Properties does not preclude license renewal for Crow Butte in situ leach uranium mine

The Nuclear Regulatory Commission's Atomic Safety and Licensing Board has released a Partial Initial Decision on challenges to renewal of the operating license of the Crow Butte uranium mine southeast of Crawford - and it's pretty much a split decision.
The Licensing Board agrees with opponents, including the Oglala Sioux Tribe, that NRC staff failed to meet National Historic Protection Act and National Environmental Polict Act requirements to work with the tribe to identify Traditional Cultural Properties in the mining lease area, but disagrees that the failures should result in denial of the license renewal.
The board says the unwillingness of the tribe and other intervenors to continue to participate in the consultation process with NRC staff weighs against their demand and that not granting renewal or extension would be an "undue hardship" on mine owner Cameco Resources and "unnecessary to cure the potential harms at issue."

Cameco defers wellfield development at Crow Butte situ leach uranium mine due to depressed uranium market

On Apr. 21, 2016, Cameco announced that production is being curtailed at Cameco Resources' US operations by deferring wellfield development. The changes are expected to result in a reduction of about 85 positions, including employees and long-term contractors.
The US operations will continue to employ about 170 people to operate existing facilities and restore depleted wellfields, but new wellfield development will be stopped. The US operations will continue ongoing licensing efforts to maintain the option to resume development when market conditions significantly improve.

Truck carrying hydrochloric acid to Crow Butte uranium in situ leach mine overturns

An Industrial Chemical truck from Denver, Colo., turned over approximately two miles from the Crow Butte Uranium Mine as it was making a delivery of hydrochloric acid to the facility. Dawes County Deputy Sheriff Scott Swickert said the accident occurred around 6 a.m. and was caused by the wintry weather conditions. "The trailer got into the soft shoulder of the road and it sucked the trailer into the ditch," he said. A small valve on the trailer broke off in the wreck, and Swickert described the hydrochloric acid as dribbling out. Neither Swickert or Crow Butte Mine knows as yet how much of the acid was spilled.
Ken Vaughan, communications director with Cameco, Crow Butte's parent company, said mine staff helped build a berm around the site of the accident to contain the spill. The Dawes County Sheriff and the Nebraska State Patrol are controlling access to the scene. (Rapid City Journal Feb. 4, 2015)

Geologist raises concern over potential groundwater contamination at Crow Butte uranium ISL mine: Hannan LaGarry, a Chadron State geology instructor, said the Crow Butte mine has ignored recent studies that show faults and fractures in underground layers of rock that could carry contaminants to aquifers used for drinking and livestock. LaGarry said he's not opposed to uranium mining but is concerned that the mine is relying on outdated studies of underground rock. "In recent years, we've found that the assumptions made by previous workers were false and that newer detailed work shows a different story," he said. (Omaha World-Herald Dec. 14, 2008)

Crow Butte in situ leach uranium mine threatened by wild fire

On July 31, 2006, Crow Butte Resources notified the U.S. Nuclear Regulatory Commission of the wild fires east of Crow Butte Resources Central Processing Plant. The NRC was informed of the possible evacuation of the Crow Butte site should the fires continue to burn out of control.

Crow Butte Resources plans to expand In Situ Leach operations

"Division of Fuel Cycle Safety and Safeguards staff has learned that Crow Butte Resources (CBR) plans to expand its in situ leach (ISL) uranium extraction operations in Nebraska by operating up to four satellite facilities. CBR estimates that it will submit a license amendment application to NRC for the first satellite facility in May 2005, and an application for a second satellite facility is targeted for 2006 - 2007. Depending on economics, applications could be submitted to NRC for license amendments for two additional satellite facilities in the 2007 - 2010 time frame. Although a memorandum of understanding to defer active groundwater regulation at ISLs may be executed with the State of Nebraska before the first license amendment is submitted in 2005, NRC must prepare environmental assessments for each application." (U.S. NRC SECY-04-0131 WEEKLY INFORMATION REPORT - WEEK ENDING JULY 16, 2004)

NRC denies Wellfield Unit 1 groundwater restoration approval

By letter dated March 29, 2002, NRC, in a rare move, denied approval for the groundwater restoration at Wellfield Unit 1 of the Crow Butte in-situ leach facility.
"Staff's analysis indicates that concentrations of ammonium, iron, radium-226, selenium, total dissolved solids, and uranium show strongly increasing concentration trends over the stability monitoring period. These trends indicate a reasonable likelihood that license limits would be exceeded in the near future."

On Aug. 11, 2011, the Nebraska Department of Environmental Quality issued the permit for the construction and operation of the North Trend Expansion Area of the Crow Butte uranium in situ leach mine.

Opposition to aquifer exemption for North Trend expansion of Crow Butte uranium in situ leach mine: Uncertainties regarding the presence of faults and factures in the land underlying northwest Nebraska are a major reason that the Crow Butte Resources uranium mine should not receive an 'aquifer exemption' for its proposed North Trend expansion project, opponents of the mine said Monday (Aug. 23).
Making a decision now to allow use of the estimated 1.85 billion gallons [7 million cubic metres] of water in the lower portions of the Chadron formation under the expansion area would be premature, countered David Frankel, an attorney representing mine opponents in hearings before the Nuclear Regulatory Commission. Detailed research by Chadron geologist Hannan LaGarry indicates that faults and fractures common in the area could link the Chadron aquifer to other water bearing layers, including the Brule and Arikaree, which are used for drinking water, he said. (Rapid City Journal Aug. 25, 2010)

The Nebraska Department of Environmental Quality has scheduled a public hearing regarding a proposal to exempt a portion of the Chadron Aquifer north of Crawford. This portion of the aquifer is associated with a proposed expansion area for the Crow Butte Resources (CBR) uranium mining facility. The proposed exemption would prevent that designated area of the aquifer from being used as a drinking water source in the future. The public hearing is scheduled for Monday, August 23, 2010.

The ownership of the Crow Butte Resources uranium mine near Crawford by a Canadian mining company is a legitimate issue for argument in deciding whether the mine should be allowed to expand its operation to a nearby site, a three-member panel of Nuclear Regulatory Commission judges has ruled. In a decision issued Jan. 27, 2009, the NRC judges also said that questions of the impact of low levels of arsenic in water returned to aquifers during mining operations, the relationship between arsenic exposure and diabetes and information about an alleged cluster of pancreatic cancer in the Chadron area can also be raised during hearings on the mine's proposed North Trend expansion.

Company abandons plan for reactivation of Mt. Taylor uranium mine: In a stunning victory for Native communities, Rio Grande Resources (RGR), owner of the Mt. Taylor uranium mine, notified the Mining and Minerals Division (MMD) of the New Mexico Energy, Minerals and Natural Resources Department of "cessation of mining operations" and RGR's intention "to begin closure plan activity."
RGR had been granted Return to Active status under their permit Dec. 29, 2017. The mine had been in Standby status since 1999.
MASE and Amigos Bravos appealed the permit revision. After hearings May 5, 2018, the Mining Commission issued their Final Order Aug 1, 2018, upholding the Return to Active status. The two organizations then appealed that ruling to the First Judicial District Court in Santa Fe; when that court upheld the Mining Commission decision, the groups appealed to the State Court of Appeals, where the case is currently located.
According to RGR, "From initiation of the closeout contracting process to completion of the closeout activities on site is estimated to take about 16 months. The first 5-6 months would be taken up by project management and contractor procurement, followed by 9-10 months of actual construction activities on site from mobilization through demobilization."

The Gallup Independent reports the Multicultural Alliance for a Safe Environment and Amigos Bravos have asked the New Mexico Court of Appeals to review a lower court ruling that upheld the New Mexico Mining Commission's decision to permit the Mount Taylor Mine to return to active status. (AP Sep. 4, 2019)

Environmental groups fight against state permit for reactivation of Mt. Taylor uranium mine: Environmentalists are seeking to keep an idle uranium mine in western New Mexico from becoming active again, saying the designation will allow it to delay cleanup.
The Multicultural Alliance for a Safe Environment and Amigos Bravos are asking the New Mexico Mining Commission to review a recent decision by state Mining and Minerals Division Director Fernando Martinez to allow the Mount Taylor mine to return to "active," or operational, status, the Gallup Independent reports.
The groups say there is no realistic likelihood that mining will take place for the foreseeable future. "The director's decision directly contradicts the New Mexico Mining Act's plain language, which restricts 'operational' mines to those that are producing minerals," said Eric Jantz, staff attorney at the New Mexico Environmental Law Center, which is representing the groups. "The director has unilaterally created an entirely new category of mine activity - 'zombie mines' - that have been given new life in an effort to avoid cleanup."
The Mount Taylor Mine has been on standby status for more than 20 years. Its owner, Rio Grande Resources, announced in 2014 that it planned to ask regulators to change the status to active. (Albuquerque Journal Mar. 19, 2018)

Group seeks public hearing over proposed reactivation of Mt. Taylor uranium mine after 23 years of inactivity: Today, the New Mexico Environmental Law Center (NMELC) filed a request for a public hearing regarding a proposed permit revision to put the Mt. Taylor uranium mine on active status. The mine, near Grants, NM, has been inactive (on "standby" status) without cleanup for 23 years. The mine's owner, Rio Grande Resources, received a fourth renewal for the standby permit in January 2012, but on April 12, 2013 it notified the public it was seeking a revision to change the mine's status to "active". The NMELC filed the hearing request on behalf of its clients, Amigos Bravos and the Multicultural Alliance for a Safe Environment (MASE). (NMELC May 10, 2013)

Mine agency to take input on renewal of standby permit requested for Mount Taylor uranium mine: The New Mexico Mining and Minerals Division has set a public hearing for Rio Grande Resources Corporation's application to renew "Standby Status" for its Mount Taylor Mine on Wednesday, Aug. 17, at 5 p.m. in the Cibola County Convention Center.
A standby permit allows the mine operator to let the mine remain inactive without having to do any clean up. The permit lasts for five years. The Mount Taylor mine is located one mile northeast of San Mateo. The mine is an existing underground uranium mine that extracted uranium ore from depths of more than 3,000 feet below ground surface using room-and-pillar and stope mining methods. Uranium ore was produced from the mine from 1979 to 1982 and from 1985 to 1990. The mine has been inactive since January 1990. A copy of Rio Grande Resources' application for the renewal of Standby Status is available at the Mother Whiteside Memorial Library and in Santa Fe at the Mining and Minerals Division's office. These documents are also available for viewing on the MMD website . (Cibola Beacon Aug. 15, 2011)

Rio Grande Resources Corporation (RGR) submitted a Standby Status Renewal Application for its Mt. Taylor Mine. The mine is an existing uranium mining operation using underground mining techniques to extract uranium ore from depths of over 3000 feet below ground surface using room-and-pillar and stope mining methods. There are no milling facilities within the proposed Standby area. The Mine has been inactive since January 1990 until the present.

A groundwater discharge permit is being sought for Mount Taylor Uranium Mine and Mill owned by Rio Grande Resources, according to the New Mexico Environment Department . Gerald Schoeppner of NMED's Groundwater Quality Bureau said Wednesday that the company has an existing discharge plan for its mine that it's trying to renew, "but that's one of the pieces of the puzzle that's missing - how they're planning to treat their mine water for the dewatering to meet standards."
The Mount Taylor mine previously was a conventional mining operation "and they plan to operate it as a conventional mine in the future," Schoeppner said. The mine site is located just outside the 8,000 foot elevation boundary established in the June 2008 emergency designation of Mount Taylor as a Traditional Cultural Property.
Rio Grande Resources controls uranium operations and mineral resources acquired by General Atomics from Chevron Resources in 1991. The Mount Taylor project, a conventional underground mine, contains the largest uranium resource in the United States and is currently on standby, according to the company's Web site. Chevron began commercial production at Mount Taylor in 1986, initially shipping the ore to its Panna Maria mill in south Texas for processing. The mine was placed on standby in 1989.

TCEQ approves license renewal for Vasquez in situ leach processing plant

On Nov. 6, 2023, enCore Energy Corp. announced the approval of the renewal of the Radioactive Materials License for enCore's In-Situ Recovery Uranium Central Processing Plant at its Vasquez uranium project.

Vasquez ISL mine shut down

During the fourth quarter of 2008, URI shut down the last wellfield at Vasquez. (URI March 11, 2009)

Vasquez ISL mine production below expectations

"Production costs for the third quarter of 2006 were $56.92 per pound compared with $23.57 per pound in the prior year's third quarter. The higher production costs were primarily due to higher capital and operating costs compared with the prior year and also due to the change in the estimated recovery factor of for the Vasquez project from 70% to 50%."
"The Vasquez project has provided significant technical challenges since its inception in 2004 due to the unique geochemical composition of its ore body and the degree of re-reduction found in the uranium deposited within the formation. When uranium has been "re-reduced" it has in nature been oxidized, reduced and then subjected to additional reductants which results in the uranium being less accepting of oxidation for extraction. These factors have contributed to our production costs at Vasquez rising from $20.32 per pound in 2005 to over $46.00 per pound in 2006."
"Our third quarter production consisted of 26,074 pounds [10 t U] from our Vasquez project [...]. Last year's third quarter production of 65,797 pounds [25.3 t U] was produced completely from the Vasquez project. As discussed, given the challenges at this property, its level of production has measurably declined and was below expectations." (URI Nov. 14, 2006)

"[...] Vasquez has continued to operate below expectations. At the beginning of the project in 2004, our mining plan indicated we could produce the Vasquez property at an annual rate of 700,000 pounds [269 t U]. The geological and chemical problems we experienced in 2005 caused us to revise that estimate downward to an annual capacity of 400,000 pounds [154 t U]. [...]" (URI Sep. 19, 2006)

Elevated uranium concentrations found in off-site domestic well near Kingsville Dome in situ leach uranium mine

"[...] The bleed at PA-3 [production area three] did not contain the increased pressures caused by injection of leaching fluids. A hydraulic gradient was rapidly established between the injection wells and the mine boundary, as shown by a rise in water levels in monitor wells surrounding PA-3. This gradient drove mining solution beyond the mine boundary. These excursions affected a well on the Garcia property, approximately 300 m down gradient of the mine. Since mining began, uranium concentrations in the Garcia well have increased from less than 200 µg/L, to more than 600 µg/L.
This is the first time that contaminants in an off-site domestic well have been linked to ISL uranium mining in the United States of America."

Whistleblower speaks out against methods once used by Uranium Resources Inc. at Kingsville Dome uranium in situ leach mine (Texas)

Roland Burrow worked as a wellfield operator for Uranium Resources, Inc., outside Kingsville, Texas a decade ago. He says the company at the time was regularly flushing high volumes of water into the mine field that would have expanded groundwater pollution beyond its permitted area, posing a potential future risk to the residents of Kingsville. He claims also to have witnessed the falsification of monitoring-well data, which must be regularly submitted to the state to show the contaminated water is contained at the mine site.
He tried unsuccessfully to get the TNRCC and FBI involved, and was fired. He moved a couple counties over, but now a URI offshoot wants to mine in his backyard (at Goliad), and he's decided to fight.

Kingsville Dome ISL mine to shut down again

During the fourth quarter of 2008, URI shut down one operating wellfield at Kingsville Dome. The two Kingsville Dome wellfields that remained in production at December 31, 2008 are expected to be depleted by the end of the first quarter of 2009. In Kleberg County, the economic downturn is leading to a slowdown at a uranium plant that's been around for two decades. In fact, the company plans to shut down temporarily over the next month and start working on restoration. (URI Mar. 11, 2009)
The uranium mining plant opened up in 1988. Ever since then, critics have asked how the company plans to clean up. With a slow down expected soon, workers have started that process.
Word about the mining coming to end concerns opponents of the uranium mines. South Texas Opposing Pollution (STOP) leaders said these mines need to be cleaned up. "They have been in the process of cleaning up in the last 20 years," said Mark Walsh, a member of STOP. "They have not cleaned out any area yet; Area 1, 2 or 3." (KIII TV3 Jan. 27, 2009)

Startup of Rosita ISL mine delayed and shut down

On June 9, 2008, Uranium Resources, Inc. announced that there has been a delay in the startup of its Rosita wellfield as a result of a number of aquifer related technical issues.
On March 11, 2009, Uranium Resources, Inc. announced that the Rosita wellfield, which proved to be a technically challenging and therefore, higher cost operation, was shut-in during October, 2008, due to lack of economic feasibility in the current price environment.

Production starts from new wellfield at Kingsville Dome ISL mine

Uranium Resources, Inc. announced on July 19, 2007, that it started production at Wellfield 14 located on the Company's Kingsville Dome project in South Texas. The Company expects to produce 120,000 to 140,000 pounds U3O8 [46 to 54 t U] over a one-year period from this wellfield. Total production costs are projected to fall within the range of $25 to $30 per pound.
The Company plans to bring its next wellfield at Kingsville Dome online in the fourth quarter of this year. The new wellfield should also produce approximately 120,000 to 140,000 pounds U3O8 within a twelve-month period.
The Company produced a total of 109,000 pounds U3O8 [42 t U] during the first quarter, and 136,000 pounds U3O8 [52 t U] during the second quarter 2007.

Restart of Kingsville Dome and Rosita ISL mines delayed

"Delays in restarting production at Kingsville Dome and Rosita have continued. Kingsville was restarted in April 2006. We planned to bring on three new wellfields, one in August and two in September. Weather problems and a shortage of available drill rigs and logging trucks have pushed off the expected startup of these wellfields by at least one month. At Rosita, the shortage of drill rigs and logging trucks has delayed estimated production until the first quarter of 2007. The shortage of drill rigs and logging trucks is the result of intense industry-wide competition for exploration and development tools." (URI Sep. 19, 2006)

Southern Nevada's top water official is raising concerns about "measurable quantities" of uranium showing up in the Colorado River, the region's primary source for drinking water. Southern Nevada Water Authority chief Pat Mulroy blames uranium mining, particularly near Moab. In a letter Monday to federal Interior Secretary Dirk Kempthorne, Mulroy urges the department to "carefully evaluate" the effect on water quality before authorizing new mining claims near the river.

Preliminary economic assessment announced for Velvet-Wood and Slick Rock uranium/vanadium mine projects

On March 30, 2023, Anfield Energy Inc. reported the results of a combined preliminary economic assessment ("PEA") for both its Utah-based Velvet-Wood Uranium and Vanadium Project and its Colorado-based Slick Rock Uranium and Vanadium Project. These two projects are located proximal to one another within the prolific Uravan Mineral Belt, and within close distance of the company's Shootaring Canyon Mill which will act as a centralized mineral processing facility in the PEA.
The PEA is based on a uranium price of US$ 70 per pound, along with a vanadium price of US$ 12 per pound. 36.5% of the total revenue is expected to come from the sale of vanadium.

Positive Preliminary Economic Assessment announced for the Velvet-Wood uranium mine project, assuming uranium price more than doubles

On June 27, 2016, Anfield Resources Inc. reported the results of its Preliminary Economic Assessment ("PEA") with regard to the Velvet-Wood Uranium Project. Velvet-Wood, as discussed herein, consists of two mine areas, located in Lisbon Valley, Utah and the Shootaring Canyon Uranium Mill, located in Ticaboo, Utah.
In the PEA, initial mineral processing will be via conventional vat or heap leaching methods conducted at Anfield's existing mineral processing facility, the Shootaring Mill, which lies approximately 180 miles from the Velvet-Wood mine area. Under this scenario, only those portions of the Shootaring Mill necessary for the final processing of pregnant leach solutions, from either a vat or heap leach facility, will be refurbished.
The PEA assumes a uranium sales price of US$ 65/lb U3O8, that is 2.5 times the current spot market price.

Preliminary Economic Assessment commissioned for the Velvet-Wood uranium mine project

On Feb. 10, 2015, Anfield Resources Inc. announced that it has engaged BRS, Inc. to complete a preliminary economic assessment for the Velvet-Wood Project.

Activist denounces poor supervision of radon emissions from uranium mines near La Sal

A southern Utah activist wants state regulators to be more thorough and more transparent in how they handle hazardous emissions from Utah's uranium mines. Sarah Fields, representing Moab-based Uranium Watch , told the Utah Air Quality Board this week that state regulators have failed to carry out basic duties when it comes to cancer-causing radon emissions from uranium mines near La Sal in southeastern Utah's San Juan County.
Fields conceded that Denison's operations now release radon at doses lower than those considered harmful by the Environmental Protection Agency, although that hasn't always been the case. She also insisted DAQ (Division of Air Quality) doesn't have all the information it needs to ensure the mines are operating safely. As an example, she questioned if it was appropriate for DAQ to allow a vent - one that had been cited in an August 2010 notice of violation from the EPA - within a quarter-mile of the La Sal School. (Salt Lake Tribune Apr. 5, 2012)

Denison Mines commences operation of La Sal mine without air quality approval order, no BLM plan of operation, and minimal environmental assessment

Denison Mines Corporation (Denison) has begun the operation of the La Sal Mine, one of the mines in the La Sal Mines Complex, without an updated Plan of Operations and Environmental Assessment and without an modified Approval Order from the Utah Division of Air Quality (DAQ). (Uranium Watch June 20, 2011)

Continuing health and safety violations at La Sal Mines Complex

The operators of the La Sal Mine Complex, Denison Mines (USA) Corporation (Beaver Shaft Mine) received 10 citations and 2 orders, Reliance Resources LLC (Pandora Mine) received 5 citations and one order from the Mine Safety and Health Administration (MSHA) for health and safety violations in March. This is in addition to 11 citations in January, with proposed penalties of $13,372. MSHA has not yet assessed the penalties for the March citations.
Two of the March orders were issued because MSHA found hazardous conditions underground similar to previously identified hazardous conditions that had resulted in sections of the mines being closed off to workers. These included hazardous ground conditions related to scaling and support-the same type of conditions that caused the fatal accident in May 2010-and the need to wear respirators when the radon daughter concentrations exceed 1 Working Level. The mines have previously been cited for these hazardous conditions.

Production restarts at Pandora uranium mine: On Dec. 21, 2023, Energy Fuels Inc. announced that, in response to strong uranium market conditions, it has commenced uranium production at its Pandora mine. Ore mined from the mine during 2024 will be stockpiled at the Company's White Mesa Mill for processing in 2025.

Mine Safety and Health Administration settles with Reliance Resources on penalties for fatal accident at Pandora mine in 2010: Mine Safety and Health Administration (MSHA) has settled with Moab based Reliance Resources LLC for penalties associated with the fatal mine accident at the Pandora Mine on May 26, 2010. Reliance Resources operated the mine in La Sal, Utah, for Denison Mines Corporation, a Canadian company. Hunter Diehl was killed when large rock fell on him. He was manually scaling loose material from the rib when it fell.

It has takenover three years to resolve these and other contested penalties. There were 46 violations at the Pandora Mine in 2010. (UraniumWatch Oct. 31, 2013)

Pandora mine to be shut down: On Oct. 17, 2012, Energy Fuels Inc. announced that it will cease mining at the Pandora property during the second quarter of FY 2013, pending the depletion of its identified uranium and vanadium resources.

Pandora mine operator fined $92,600 for fatal accident: The Mine Safety and Health Administration (MSHA) has issued a penalty of $92,600 to Reliance Resources, LLC, for two violations from the fatal accident on May 26, 2010, at the Pandora Mine (Mine ID 4200470), La Sal, San Juan County, Utah. (UraniumWatch May 7, 2011)

More worker health and safety violations at La Sal mines: The January 2011 Mine Safety and Health Administration (MSHA) inspections resulted in 5 worker health and safety violations at the Pandora Mine for Reliance Resources LLC and 6 violations at the Beaver Shaft for Denison Mines (USA) Corp. All MSHA violations were associated with the failure of the mine operators to properly protect the workers from exposure to radon daughters (short lived, highly radioactive particulates from the decay of radon) in the mines.
Both Denison Mines and Reliance Resources were cited for exposure of workers to air with concentrations of radon daughters exceeding 1.0 working level (WL) in active workings and for the failure of workers to wear respirators in areas where the radon daughters exceed 1.0 WL. Reliance Resources was also cited for improper ventilation, not posting inactive workings where radon daughter concentrations are about 1.0 WL, and failure to calculate and record complete individual exposures in active working areas with radon daughter concentrations are more than .03 WL. This followed an inspection of December 20 when Denison was fined $6,000 for exposure of workers to radon daughters above the acceptable level, improper ventilation, and failure to calculate and document worker exposure to radon daughters, or progeny.
At the beginning of December, Denison was citied for 12 other violations, some for the same violations that Reliance Resources was cited for after Hunter Diehl was killed at the Pandora Mine 2010. Denison failed to correct hazardous conditions associated with scaling and support and failed to have a competent person examine each working place at least once each shift for conditions that may adversely affect safety or health.
In 2009 Denison received 13 citations; Reliance Resources received 14; total penalties for all were $3,629. In 2010, Denison received 34 citations and orders; total penalties of $18,304. Reliance Resources received 18 citations and orders; total penalties of $2,664 (this does not include any penalties associated with the fatal Pandora Mine accident on May 26, 2010).
Denison has been ajusting its ventilation system to reduce radon emissions so that they do not exceed the standard for doses to the nearest residents, La Sal School, and road maintenance shed. It is difficult for Denison to meet both the dose standard for off-site exposures to radon and the underground worker exposure standards.

Judge approves drilling at Pandora uranium mine in Manti-La Sal National Forest: A federal judge will allow a uranium mining company to drill several new holes in the Manti-La Sal National Forest. Three Moab conservation groups had asked Judge Dale A. Kimball to halt the drilling planned by Denison Mines Corp. at its Pandora Mine, claiming the U.S. Forest Service permitted the project without an adequate environmental study. Uranium Watch, Center for Water Advocacy and Living Rivers argued that Denison would create radioactive air emissions and heavy metal contamination if it drills 16 exploration holes and two radon vent holes, a project approved by the Forest Service. Kimball gave more weight to Denison's environmental expert, who said there was no significant risk of environmental harm. Kimball also wrote that the Forest Service followed procedural rules when it allowed the project without environmental assessments or impact statements. (Salt Lake Tribune Sep 14, 2010)

Groups file suit to stop expansion of Pandora uranium mine in La Sal, Utah: Uranium Watch, Center for Water Advocacy, and Living Rivers, conservation groups located in Moab, Utah, yesterday (July 29) filed suit in federal district court in Salt Lake City to halt uranium exploration and the construction of radon vent holes on U.S. Forest Service land in the Manti-La Sal National Forest in La Sal, Utah.
The complaint filed with the United States District Court for the District of Utah challenges a decision by the Moab/Monticello Ranger District to permit the drilling of 16 exploration drill holes and 2 radon vent holes as part of the expansion of the Pandora Uranium Mine.
Radon is vented to the surface from the underground mine operations so that the miners will not breath in the radon gas and be exposed to the short-lived highly radioactive particles that are produced when radon decays. The proposed radon vents would add to the amount of radon gas and radioactive particulates released in the vicinity of the community of La Sal, on the south slope of the La Sal Mountains. In 2009, the amount of radon released from the uranium mines in La Sal jumped from 300 Curies to over 4,500 Curies, according to Denison's annual reports to the Utah Division of Air Quality. Radon is released from vents near the Beaver Shaft not far from the La Sal Elementary School. (Uranium Watch, July 30, 2010)

Uranium miner dies in rockfall accident in Pandora mine: A 28-year-old uranium miner from Moab died Wednesday (May 26) morning after he was hit by falling rock in the Pandora mine near LaSal, San Juan County. (The Salt Lake Tribune May 26, 2010)
Federal regulators faulted a Utah company for safety lapses in the death of a uranium miner who was killed by a large rock slab he was peeling off a tunnel wall near La Sal. A Mine Safety and Health Administration report released Thursday (Sep. 23) said Reliance Resources LLC of Moab was cited for inadequate worker training and failing to test a tunnel wall for loose rock. The citations were rescinded after the company took corrective measures. The report says 28-year-old Hunter Diehl ("deal") of Moab was using a pry bar to pull off loose slabs May 26 when one fell on top of him. He was pronounced dead later at a hospital.
