Uranium Rock Chip Sampling Assay Results

 

Ore-Grade Uranium, Vanadium and Copper Assays Confirmed in Historical Mining
Areas at UV Project, Colorado

 

Metals One plc (AIM: MET1), a critical and precious metals exploration and
development company, is pleased to announce the results of reconnaissance rock
chip sampling and scintillometer surveying at its Uravan Uranium-Vanadium
Project in Montrose County, Colorado (the "Project").

 

A total of 19 rock chip samples were collected from across the claim block and
surrounding areas. The samples were analysed for uranium, vanadium and
associated elements, with full QA/QC protocols including blanks, standards and
duplicates.

 

Highlights:

 

·    Uranium assays up to 41,768 ppm U (4.17%) from historic waste
material (UV5).

·    Vanadium assays up to 24,688 99m V (2.46% V) (UV16, waste dump).

·    Copper up to 11,449 ppm Cu (1.14% Cu) (UV16).

·    Silver up to 99.4 g/t Ag (UV5).

·    Pathfinder elements typical of redox-front uranium systems, including
molybdenum (108 ppm), selenium (32 ppm) and arsenic (428 ppm), coincident with
high uranium-vanadium values.

·    Results confirm uranium-vanadium-copper-silver association typical of
Salt Wash Member (Morrison Formation), which is known to host uranium
deposits.

·    Sampling included historic waste dumps and limited outcrop.

Scintillometer Survey

 

A RS-125 spectral scintillometer survey over the UV claim block identified
numerous high-count anomalies (>3× background, up to 27,000 CPS), mostly
coinciding with historic mine sites, but also including moderate anomalies in
areas without recorded workings (see Figure 2 below):

 

·    Red category (>400 CPS) anomalies cluster around historical adits.

·    Green anomalies (above 250 CPS) represent anomalous above background
readings.

Sampling Context

 

·    Majority from historic waste dumps associated with former
uranium-vanadium workings, confirming the high tenor of ore historically mined
in the district

·    Limited in-situ material sampled, notably UV16 (outcrop adjacent to
adit) and UV19 (mine working face plus waste)

·    Mineralisation hosted in sandstone of the Salt Wash Member, Morrison
Formation, dominated by carnotite and uraninite, with some roscoelite

 

Craig Moulton, Chairman of Metals One, commented:

 

"These results indicate the exceptional grades historically mined from the
Project, with multiple samples containing uranium and vanadium at ore-grade
levels. While these results are not from in-situ mineralisation and cannot be
taken as indicative of average grades, they provide strong validation of the
scintillometer anomalies identified in our survey and evidence of high value
material mined historically from many visible adits.

 

Our next steps will involve surveying the historical adits across the
anticline to understand the extent and grade of these occurrences and
therefore determine the exploration potential of the Project."

Appendix 1a: Section 1: Sampling Techniques and Data

 

 Criteria                                                 Commentary
 Sampling Techniques                                      19 rock-chip samples were collected from waste dumps and limited outcrop
                                                          exposures. Samples were first screened using a scintillometer and then sent
                                                          for laboratory analysis with ore-grade assay methods.
 Drilling Techniques                                      No drilling has been undertaken. Results are from surface reconnaissance
                                                          sampling only.
 Sample Recovery                                          Not applicable, as no drilling has been completed. Rock-chip samples were
                                                          hand-selected from exposed material.
 Logging                                                  Samples were field logged with notes on lithology, mineral occurrence, and
                                                          whether material was derived from dumps or outcrop.
 Sub-sampling Techniques and Sample Preparation           Samples were submitted directly to the laboratory. The lab employed
                                                          industry-standard QA/QC procedures, including standards and duplicates.
 Quality of Assay Data and Laboratory Tests               Assays were conducted by an accredited laboratory using ICP-MS with ore-grade
                                                          detection limits. Field scintillometer readings were used as a guide only.
 Verification of Sampling and Assaying                    Scintillometer readings cross-checked with assays. No umpire laboratory checks
                                                          have yet been undertaken.
 Location of Data Points                                  Sample locations recorded using handheld GPS with approximately ±5 m
                                                          accuracy. Coordinates reported in WGS84 datum.
 Data Spacing and Distribution                            Reconnaissance sampling only. Sample locations are irregular and selective
                                                          rather than systematic.
 Orientation of Data in Relation to Geological Structure  Samples were selective, based on visible mineralisation in dumps and outcrop.
                                                          Orientation not considered material at this stage.
 Sample Security                                          Samples were retained in custody of the field team before dispatch to the
                                                          laboratory.
 Audits or Reviews                                        No external audits or reviews of sampling techniques or data have yet been
                                                          undertaken.

Appendix 2: Technical Glossary

 

Adit
A nearly horizontal tunnel driven into the side of a hill or mountain to
access an underground mine. Adits are used for entry, drainage, and
ventilation, and often provide access directly to an ore body without the need
for vertical shafts.

 

Counts per Second (CPS)

The unit used by scintillometers to record radiation intensity, expressed as
the number of gamma-ray counts detected per second. Higher CPS values usually
indicate elevated uranium or thorium.

 

Carnotite

A bright yellow uranium-vanadium mineral  K₂(UO₂)₂(VO₄)₂·3H₂O 
that is a primary ore of both uranium and vanadium.

 

Ore-grade

A concentration of metal in rock that is considered high enough to be of
economic interest, depending on market prices and mining conditions.

 

ppm (parts per million)

A unit of concentration used in geochemistry and assay reporting. For metals,
10,000 ppm equals 1% by weight.

 

QA/QC (Quality Assurance/Quality Control)

Industry standard procedures involving blanks, standards, and duplicates to
ensure assay reliability and accuracy.

 

Redox-Front Uranium Systems

Uranium deposits that form where oxidised, uranium-bearing fluids encounter
reducing conditions in the subsurface (e.g., organic matter, sulphides). At
this chemical "front," uranium precipitates out of solution, creating
mineralisation.

 

Roscoelite

A vanadium-bearing mica mineral (K(V³⁺,Al,Mg)₂(AlSi₃O₁₀)(OH)₂)
that often occurs in association with vanadium-uranium mineralisation in
sandstones.

 

Salt Wash Member (Morrison Formation)

A Jurassic-age sandstone unit within the Morrison Formation of the Colorado
Plateau. Known historically as one of the most important hosts of
uranium-vanadium mineralisation in the United States.

 

Scintillometer Surveying

A field technique using a handheld instrument that measures natural gamma
radiation emitted from rocks. Useful for detecting uranium mineralisation at
surface or near-surface.

 

Uraninite

A uranium oxide mineral (UO₂), typically black, dense, and radioactive. It
is the most important primary uranium ore mineral worldwide.
