7 terms

u3o8 medical

"record >3,000 ppm U₃O₈, confirming the district's strong uranium-vanadium"

U3O8 is the chemical name for a stable form of uranium oxide commonly called “yellowcake,” the concentrated powder produced after uranium ore is processed. Investors track U3O8 because it represents the raw material that is turned into nuclear fuel; its supply, demand and price act like a commodity indicator that can move the value of mining companies, utilities and firms tied to the nuclear fuel chain. Think of it as the crude oil equivalent for nuclear power — a basic feedstock whose availability and cost affect an entire industry.

v2o5 medical

"historic assays up to 0.45% U₃O₈ and 3.45% V₂O₅."

V2O5 is the chemical formula for vanadium pentoxide, a hard, yellowish compound used as a raw material in metal alloys, catalysts and certain battery and energy-storage components. Investors care about it because changes in its supply, demand or price can affect the costs and profitability of mining, steelmaking and battery-related companies—much like fuel prices influence transportation firms—and therefore can move the value of related stocks.

carnotite medical

"collect additional rock samples from any zones of visible carnotite or anomalous"

Carnotite is a yellow-green mineral that contains both uranium and vanadium, often found in sandstone and other sedimentary rocks. For investors, it matters because deposits can be a source of uranium used in nuclear fuel and vanadium used in steel and energy-storage technologies, so discoveries or changes in production can affect supply, prices, regulatory risk, and the viability of mining projects much like finding a new oil pocket can reshape prospects for an energy firm.

scintillometer technical

"with scintillometer readings up to 45,200 cps."

A scintillometer is an instrument that senses and quantifies tiny flashes of light created when radiation or energetic particles hit a detector, or it can track small variations in light over a distance to measure air turbulence. For investors, scintillometer measurements can reveal hidden risks or opportunities—such as evidence of radioactive contamination, mineral or resource indicators, or environmental conditions that affect operations and regulatory compliance—acting like a remote alarm or spotlight for issues that influence value and legal exposure.

radiological medical

"including radiological scanning, mapping and characterisation."

Relating to medical imaging or the use of ionizing radiation for diagnosis and treatment, such as X-rays, CT scans, MRIs, or radiation therapy; it covers the equipment, procedures, and safety controls used to create images of the body or deliver targeted radiation. Investors care because radiological technologies drive revenue in hospitals, diagnostic centers and device makers, influence reimbursement and regulatory risk, and can be a competitive advantage much like a faster, more accurate camera in a photographer’s kit.

bench-scale technical

"DISA will undertake bench-scale testing on a bulk sample of mineralized"

A bench-scale process or experiment is a small, laboratory-level version of a product or manufacturing step used to test whether an idea works in practice before moving to larger pilot or production stages. For investors it signals early technical progress and remaining risk: successful bench-scale results show the concept can work, but scaling up can introduce new costs, complexity, or failures—like a recipe that succeeds in a small pan but may behave differently when made for a crowd.

nrc license regulatory

"in accordance with the requirements of DISA's NRC license."

An NRC license is an official permit issued by the U.S. Nuclear Regulatory Commission allowing an organization to possess, use, transport or operate radioactive materials or nuclear facilities, including reactors and medical or industrial isotope production. For investors, it’s critical because the permit determines whether core operations can legally run, influences timing and costs of projects, and represents regulatory risk—similar to a building permit or driver’s license that must be obtained and maintained for business activity to continue.

HIGHLIGHTS

• More than 60 historic drillholes digitised to date record >3,000 ppm U₃O₈, confirming the district's strong uranium-vanadium signature.

• Mapping of a 700 ppm U₃O₈ cut-off envelope underway, defining multiple coherent mineralised trends.

• A distinct northwest target zone (Dakota/Burro Canyon) identified, with historic assays up to 0.45% U₃O₈ and 3.45% V₂O₅.

• UAR enters a collaboration with DISA Technologies to undertake bench-scale metallurgical test work and site surveys at no cost to UAR.

WOODLAND HILLS, CALIFORNIA / ACCESS Newswire / December 8, 2025 / Uranium American Resources, Inc. (OTC:UARI) is pleased to provide an update on work underway at the Stateline Uranium-Vanadium Project, located in the La Sal Creek mining district.

Following a comprehensive data-recovery trip to Denver, the Company has digitized a substantial volume of historic drilling, including assay sheets, drill logs, maps and geological plates. Early outcomes confirm more than 60 historic drillholes report uranium grades above 3,000 ppm, supporting the robust mineralization historically mined in the district.

Interpretation is progressing, with initial 700 ppm U₃O₈ cut-off maps outlining multiple mineralized trends across the north and south rims of the property. A separate cluster of historic holes nearby reports uranium grades up to 0.45% U₃O₈ and vanadium up to 3.45% V₂O₅. Collar accuracy in this area is uncertain and will be verified in the upcoming field program.

To complete dataset validation and prepare for modern 3-D modelling, UAR has authorised the next phase of technical work, including:

• Sub-meter GPS surveying to confirm historic collar positions,

• Integration of depth, thickness and interval type, now in progress,

• GIS-based target mapping, incorporating structure, cut-off envelopes and mineralized trends.

During the survey, field crews will collect additional rock samples from any zones of visible carnotite or anomalous scintillometer response, extending on the Company's 2024 sampling campaign that yielded assays above 1% uranium and 1% vanadium, with scintillometer readings up to 45,200 cps.

Collaboration to Support Metallurgical Test Work

UAR also advises that it has entered into a non-binding agreement with DISA Technologies Inc. to support preliminary metallurgical test work on Stateline material. Under this collaboration, DISA will undertake bench-scale testing on a bulk sample of mineralized material and carry out non-invasive site surveys, including radiological scanning, mapping and characterisation.

This work is intended to evaluate the suitability of DISA's processing technology for Stateline-style uranium-vanadium mineralisation and will be completed at no cost to UAR. The metallurgical sampling will be undertaken in parallel with UAR's upcoming field program. The Company will provide further updates as results become available.

DISA may also seek to apply its technology to the remediation and recovery of legacy uranium & vanadium site materials, following completion of its characterization program and in accordance with the requirements of DISA's NRC license.

CEO Bill Hunter commented:

"Stateline continues to show the hallmarks of a high-grade historic uranium-vanadium system. Our data integration work is rapidly bringing the project onto a modern technical footing, and the support from DISA Technologies adds meaningful depth to this effort. We appreciate DISA's collaborative approach and their commitment to completing metallurgical test work and site surveys at their cost. Partnerships like this strengthen our understanding of Stateline's potential and help advance the project efficiently and intelligently."

Field surveying is expected to commence in March, subject to weather conditions.

The Company continues to engage with external technical groups under confidentiality agreements, reflecting broad interest in UAR's uranium-vanadium portfolio.
