48x Rare Earth Upgrade to 5.9% TREO
Victory Metals Limited (ASX:VTM) ("Victory" or "the Company") is pleased to
announce outstanding first-pass sighter flotation test-work results from its 100%
owned North Stanmore regolith-hosted Heavy Rare Earth Element Project in
Western Australia.
These exceptional results have delivered a remarkable 48x upgrade in Total Rare
Earth Oxide (TREO) concentration from the raw ore, confirming the potential for a
simple, low-cost physical beneficiation circuit.
By pioneering a new method of extraction for these rare earths that separates them
from the rest of the ore mass early in the process, Victory Metals is establishing a
significantly faster and less costly path to market.
Importantly, the tests successfully concentrated a representative 1,251 ppm TREO
head grade, in the vicinity to Victory’s high grade shallow zone, to a peak concentrate
grade of 5.9 wt.% TREO, while achieving rapid flotation kinetics and preserving the
deposit’s premium 38% HREO/TREO ratio.
HIGHLIGHTS
• First pass sighter flotation on representative composite successfully upgraded
a TREO to a peak concentrate grade of 5.9% TREO (59,467 ppm).
• These outstanding results demonstrate that VTM hydrometallurgical plant will
be in the vicinity of ~5tph, a fraction of the size of initial engineering designs.
• Rougher flotation achieved 81.5% TREO recovery. Subsequent cleaner flotation,
conducted on a high-grade rougher concentrate captured in the first 7
minutes of a bulk rougher float, achieved an 83.6% stage recovery.
• The simple, conventional flotation circuit achieved these results without the
need for front-end desliming, preserving valuable fines.
• Critical HREO ratio 38% HREO/TREO delivering premium Dy, Tb, Y basket value
matching the in-situ ore ratios.
• Quantitative Automated Mineralogical Analysis (TIMA) confirms >99% of
Yttrium (proxy for HREE) is hosted in discrete, well-liberated secondary
phosphates (rhabdophane and churchite), which are highly responsive to
standard froth flotation.
• The ability to physically reject >95% of the ore mass upstream provides
optionality to substantially reduce the plant sizing and CAPEX in the
upcoming Pre-Feasibility Study (target release Q2 2026)

Victory Metals Chief Executive Officer and Executive Director Brendan Clark
commented: “These flotation results are a genuine game changer for North
Stanmore and for Western heavy rare earth supply. By proving the rare earths are
hosted in simple, floatable world class secondary phosphate minerals (rhabdophane
and churchite), we have unlocked a low-cost physical beneficiation step that most
clay-hosted and hard rock rare earth projects simply have not achieved.
This is transformative, as we can now reject ~95% of the ore mass upstream. This
gives Victory the opportunity to reach the market, faster and with greater heavy rare
earth element diversity through this valuable concentrate.
We are incorporating these results directly into the PFS. This will provide even more
optionality, including a low CAPEX & OPEX flotation circuit and with the ability to sell
one of the highest-grade, reported heavy rare earth concentrates to downstream
partners.”
Flotation Results & Circuit Dynamics
First-pass initial flotation test-work was conducted on representative composites
sourced from 47 sample metres across 10 different drillholes within the Indicated
Resource.
To evaluate the upgrade potential, two distinct sighter tests were conducted:
1. Standard Bench Rougher: A whole-of-ore rougher flotation test demonstrated
strong baseline recoveries, achieving 81.5% TREO recovery directly from the
1,218 ppm TREO head feed.

2. Cleaner Flotation on Fast-Floating Fraction: To test the maximum upgrade
potential, cleaner flotation was performed on a high-grade rougher
concentrate mass-pull taken from the first 7 minutes of a separate bulk
rougher run. This demonstrated the exceptional, rapid kinetics of the
secondary phosphates. This cleaner stage produced a combined concentrate
grade of 5.3% TREO (peak grade 5.9 wt. % TREO) with an 83.6% stage recovery.

The North Stanmore Advantage
The exceptional flotation response is directly driven by North Stanmore’s unique
mineralogy. The deposit occurs in a ~40-45 million-year-old weathering crust above
an alkaline intrusion. Intense chemical weathering, aided by organic acids, facilitated
the breakdown of primary, refractory rare earth minerals (like monazite and
xenotime) into secondary, hydrated phosphates.
Recent TIMA studies, conducted on higher-grade metallurgical sample from within
the ore body to ensure accurate analytical resolution, confirm that the rare earths are
not locked in refractory primary minerals, but are predominantly hosted in highly
liberated, discrete secondary phosphates (rhabdophane and churchite).

Figure 1. Proposed flotation circuit
Secondary REE Phosphates vs. Primary REE Phosphates Comparison
Processing Churchite and Rhabdophane represents a significant shift in
metallurgical strategy compared to traditional monazite or xenotime processing.
Churchite and rhabdophane are secondary (hydrated) phosphates, and are
thermodynamically metastable and physically softer than their anhydrous primary
counterparts. Their rare earth chemistry Ce/Ce*<1, indicates that they formed by
oxidation during weathering.

remains highly manageable and
exceptionally low compared to
primary hard-rock deposits.
High: Monazite specifically is a
major host for Thorium (Th) and
Xenotime is a major host for
Uranium (U) resulting in
concentrates that are well above
10Bq/g, resulting in Class 7 radio-

• The North Stanmore drilling that contributed to the July 2025
MRE is shown as follows -
• (AC) Air core drillholes were drilled vertically and spaced 100m
apart along 200m - 400m spaced drill lines.
• (AC) drilling samples were collected as 1-m samples from the
rig cyclone. Each sample was placed into large green drill bags
(900mmx600mm) for temporary storage onsite.
• Each sample was then split using a 3-tier (87.5% - 12.5%) splitter
and the split sample was placed into calico sample bags for
transport to Perth.
• Sample weights and recoveries were recorded on site and
weighed 1.5 - 2.5 kg depending on the sample recovery from
the drill hole. The mean bulk sample weight was 8.45kg.
• A commercial transport company was used to transport the
bags to the Victory warehouse in Perth.
• A handheld pXRF analyzer (Olympus Vanta) was used to
determine anomalous REO (Rare earth element) geochemistry
(La, Ce, Pr, Nd and Y) from the 1-m sample piles. pXRF reading
times were 45 secs over 3 cycles for multielement and REO
assays. These results are not considered dependable without
calibration using chemical analysis from an accredited
laboratory. However, their integrity was checked using
Certified REO -bearing geochemical standards.
• The handheld pXRF is used as a guide to the relative presence
or absence of certain elements, including REOs vectors (La, Ce,
Pr, Nd and Y) to help direct the sampling program. Anomalous
1m samples were then transported to the assay lab for analysis
by Victory personnel. REO anomalism thresholds are
determined by VTM technical lead based on historical data
analysis. Currently the anomaly threshold is plus 30ppm

• Victory attended North Stanmore to collect the green sample
bag which was transported by Victory to Victory’s secure
warehouse in Perth.
• Measures taken to ensure sample representivity included
regular cleaning of the rig between drill holes using
compressed air and weighing the bulk sample to ensure
reasonable sample return against an expected target weight.
• RC drill samples were collected as 1-m samples from the rig
cyclone and placed on top of black plastic, that was laid on the
natural ground surface to prevent contamination, in separate
piles and in orderly rows. A hand-held trowel was used to
collect 4-m composite samples from the 1-m piles.
Compositing did not account for lithology changes. These
composite samples weighed between 2 and 3 kg.
Drilling
techniques
• Drill type (e.g.
core, reverse
circulation, open-
hole hammer,
rotary air blast,
auger, Bangka,

details (e.g. core
diameter, triple or
standard tube,
depth of diamond
tails, face-
sampling bit or
other type,
whether core is
oriented and if so,
by what method,
etc.).
• (AC) drilling uses a three bladed steel or tungsten drill bit to
penetrate the weathered layer of loose soil and rock fragments.
The drill rods are hollow and have an inner tube with an outer
barrel (similar to RC drilling).
• (AC) drilling uses small compressors (750 cfm/250 psi) to drill
holes into the weathered layer of loose soil and fragments of
rock.
• (RC) Drilling used a 5½” face sampling hammer with
1,350cfm/500 psi onboard compressor, which was occasionally
supplemented with an additional booster (2,100cfm/1,000 psi).
• After drilling is complete, an injection of compressed air is
unleashed into the space between the inner tube and the drill
rods inside wall, which flushes the cuttings up and out of the
drill hole through the rod’s inner tube, resulting in less chance
of cross-contamination.
• (AC) Drilling was conducted by Seismic Drilling Pty Ltd and
Orlando Drilling Pty Ltd, and the RC drilling was performed by
Orlando Drilling Pty Ltd.
• The drill rigs were inspected daily by VTM personnel for safety
and rig hygiene

• Field diamond duplicate data points taken from the same
drillholes is available only for 14 samples from diamond drill
core. The mean grade of the original sample was generally
reproduced by the duplicate for the various analytes and is
acceptable to the Competent Person.
• In April 2024, 37 samples were submitted to an umpire
laboratory, Intertek Genalysis in Perth. The results were
compared to the original assay results from ALS laboratories
for the key analytes of interest to the project. There was no
observable bias between the original assays completed by ALS
and the checks completed by Intertek Genalysis Perth.
• There are only 14 duplicates collected over the entire project
drilling campaign. MEC recommends that future drilling
campaigns will require an increase in duplicate samples to be
collected to demonstrate the lack of sample bias in the rig-
mounted splitter.

remaining holes were surveyed by handheld GPS with a
horizontal accuracy of +/- 5 m. Elevation values (Z) were
assigned from the topography surface where no DGPS data
was available.
• There were no downhole surveys completed. Drillholes were

• Given the nature of the exploration programs, the spacing of
the exploration drilling is appropriate for understanding the
exploration potential and the identification of structural
controls on the mineralisation. In areas of closer spaced drilling
the spacing demonstrates grade and geological continuity
sufficient to support Indicated Mineral Resources. Where
drillhole spacing increases, grade and geological continuity
can be implied and has been classified as an Inferred Mineral
Resource. Areas where the drillhole spacing is such that grade
and geological continuity cannot be implied, have been
excluded from the Mineral Resource.
