US to fast track Laramide’s uranium project

Maddison Elliott 07 May, 2025

Laramide Resources’ (ASX:LAM) La Jara Mesa Uranium Project, located in the Grants mineral Belt of New Mexico, has been added to the US Federal Permitting Dashboard, which prioritises reliable supplies of critical minerals.

This inclusion falls under President Donald Trump’s executive order to increase mineral production in North America.

Laramide says the designation identifies La Jara Mesa’s “strategic importance” to domestic uranium production.

The order paves the way for the secretary of defence to include mineral production as a priority industrial capability development area under the Industrial Base Analysis and Sustainment Program, positioning uranium and other critical minerals as a national security imperative.

By developing resources for domestic minerals, the government is aiming to lower barriers to entry and mobilise existing funding to support the private sector.

The designation is designed to enhance transparency and accountability by making environmental review timelines accessible to the public.

Laramide, which has a market capitalisation of $188.85 million, says government, industry and community stakeholders will be able to monitor progress of the project and it will ensure a more efficient and coordinated permitting process.

CEO Marc Henderson says the designation is a meaningful milestone that reflects both the strategic value of uranium to US energy security and the importance of developing domestic sources of supply.

“The enhanced transparency and coordination process will facilitate an efficient path forward to advancing La Jara Mesa to production,” he says.

Laramide Resources is an exploration company focusing on the development of high-quality uranium assets in Australia and the US.

First concrete for US advanced reactor

Thursday, 8 May 2025

Kairos Power has announced the start of installation of nuclear safety-related concrete marking the start of "nuclear construction" for the Hermes Low-Power Demonstration Reactor project in Oak Ridge, Tennessee.

Kairos broke ground for the scaled demonstration of its KP-FHR fluoride salt-cooled high-temperature reactor technology last July, with excavation works completed in October. Safety-related construction activities, which are subject to oversight from the US Nuclear Regulatory Commission (NRC), formally began on 1 May, with the start of work on the piers that will form part of the building's foundation. Hermes will have 51 such piers, which are six feet (just under 2 metres) in diameter and will extend about 40 feet below ground, anchoring the building to bedrock.

Kairos Power CEO and co-founder Mike Laufer described the first safety-related concrete pour for a US advanced reactor under an NRC construction permit as a major milestone. "This achievement reflects the value of our iterative development process to meet the necessary nuclear quality standards and provide crucial real cost information that gives confidence to our customers. It is a testament to the hard work of our dedicated team and represents an enormous amount of learning and progress," he said.

The concrete pour was the culmination of several months of preparation, Kairos said, coming after programmes to test the drilled pier installation process and refine the company's nuclear quality assurance programme. A full-scale test pier was completed in November, and 70 piers have now been drilled for Kairos Power's ETU 3.0 non-nuclear engineering test unit, which is being built adjacent to the Hermes site as part of Kairos's iterative approach for the development of its KP-FHR technology. It says this has enabled the team, led by Barnard Construction Company, Inc, to become proficient at installing piers using quality control checklists similar to those that will be used for Hermes.

The Hermes reactor will use tri-structural isotropic (TRISO) uranium fuel and a mixture of lithium fluoride and beryllium fluoride salts known as Flibe as its coolant. This combination yields robust inherent safety while simplifying the reactor's design, Kairos said.

Hermes, which is supported by risk reduction funding from the US Department of Energy's Advanced Reactor Demonstration Program, is the first non-light-water reactor to be permitted in the USA in more than 50 years. It will not produce electricity, but Hermes 2 - a two 35 MWt-unit plant for which the US Nuclear Regulatory Commission issued a construction permit in November - will include a power generation system. The commercial deployment of the reactor is supported by a master plant development agreement signed with Google in October 2024, for power from a fleet of up to 500 MW of capacity by 2035.

Scoping study confirms robust economics for Tallahassee uranium project

6th May 2025 By: Mariaan Webb

ASX-listed Global Uranium and Enrichment (GUE) has released a scoping study for the Hansen deposit, part of its Tallahassee uranium project in Colorado, US, confirming a technically viable and economically attractive development opportunity.

The study supports a seven-year mine life, with average production of 1.8-million pounds a year of uranium oxide (U₃O₈). The base case scenario at a uranium price of $90/lb delivers a pre-tax net present value (NPV) of $203-million and an internal rate of return (IRR) of 93%. At $110/lb, the NPV increases to $365-million and the IRR to 145%.

MD Andrew Ferrier described the Hansen deposit as a standout opportunity within the world-class Tallahassee project, which is home to one of the largest undeveloped uranium deposits in the US.

"This scoping study and the impressive results generated, highlighted by a pre-tax IRR of 93% and an NPV of $203-million at $90/lb for U₃O₈, sets out a technically and environmentally viable pathway for Global Uranium to progress its development as we continue to execute on our growth strategy of building a 100-million-pound uranium portfolio."

Pre-production capital costs are estimated at $76-million, with cash operating costs of $58.65/lb U₃O₈, based on a contract ore processing scenario. The mining target comprises 15.2-million pounds of U₃O₈ contained in 5.7-million tonnes of material grading 0.12% U₃O₈, of which 12.9-million pounds will be recovered after beneficiation.

Utah uranium project fast-tracked under US emergency procedures

Wednesday, 14 May 2025

The US Department of the Interior has announced it will expedite the permitting review of Anfield Energy's Velvet-Wood mine in Utah under newly established emergency procedures, with a completion timeline of 14 days for an accelerated environmental review by the Bureau of Land Management.


The accelerated review is part of a strategic response to the national energy emergency declared by President Donald Trump in January, the department said, and is expected to "significantly contribute to meeting urgent energy demands" as well as addressing national energy security concerns. Velvet-Wood is the first uranium project to be prioritised under the emergency procedures.

"The expedited mining project review represents exactly the kind of decisive action we need to secure our energy future," said Secretary of the Interior Doug Burgum. "By cutting needless delays, we’re supporting good-paying American jobs while strengthening our national security and putting the country on a path to true energy independence."

Anfield acquired the Velvet-Wood uranium and vanadium mine from Uranium One in 2015. Some 4 million pounds U3O8 (1539 tU) - as well as 5 million pounds of V2O5 - were recovered from the Velvet deposit between 1979 and 1984 by previous owner Atlas Minerals. The combined Velvet and Wood historical mines are currently estimated to contain 4.6 million pounds U3O8 of measured and indicated resources and inferred resources of 552,000 pounds U3O8.

Anfield submitted a Plan of Operation for the mine to the State of Utah and the Bureau of Land Management in May 2024. It is advancing Velvet-Wood towards production-ready status concurrently with the Shootaring Canyon mill. The Plan of Operation includes specific operating actions and controls, reclamation actions, an estimate of reclamation surety based on third-party costs and technical bases for how the actions meet state and federal regulatory requirements.

Anfield CEO Corey Dias said the company was pleased that Velvet-Wood had been selected for expedited permitting. "As a past-producing uranium and vanadium mine with a small environmental footprint, Velvet-Wood is well-suited for this accelerated review," he said. "This marks a major milestone for Anfield as we look to play a meaningful role in rebuilding America's domestic uranium and vanadium supply chain and reducing reliance on imports from Russia and China."
