advanced Gallium projects in Australia
•
Gallium successfully recovered using low-CAPEX leaching process
•
Recovery occurred concurrently with REEs, requiring no additional processing stages
•
Offtake discussions underway
•
Commencement of upgraded Mineral Resource Estimate to now include Gallium
•
Victory’s MREC now contains a strategic mix of high value critical Rare Earth Elements,
including, Dysprosium and Terbium as well as Gallium
•
MREC and metallurgical recoveries based on a total of 57 different drillholes across the
North Stanmore project 1
•
During December 2024, China announced a ban on Gallium2 exports
•
Terbium set to also follow Gallium, with China recently restricting its export as well3
Victory’s CEO and Executive Director Brendan Clark commented:
“This is a landmark milestone, not just for Victory but for Australia’s position in the global critical
minerals landscape. To our knowledge, we are the first Australian company to confirm the
successful recovery of Gallium in a final Mixed Rare Earth Carbonate (MREC) product — and that
puts us in a league of our own.
Gallium is one of the most strategically important elements of the 21st century. It’s critical to
semiconductors, AI chips, defense systems, and next-gen communications. With China’s recent
export bans, the world is urgently searching for secure, western-aligned Gallium supply and Victory
is a potential solution.
The successful recovery of Gallium in our MREC further strengthens the commercial appeal of the
MREC and sets Victory apart globally.

MREC Metallurgical Process
Rare earth elements were extracted from material taken from samples collected from 13 AC drill
holes from North Stanmore, leaching at low temperature and pressure, and with a 4-hour residence
time.
Impurities, including Aluminum (Al) and Iron (Fe), were first removed from the leach liquor by
neutralising with commercial grade sodium carbonate (soda ash) at ambient temperature.
Rare Earth Elements & Gallium were precipitated from the impurity removal liquor using
commercial grade soda ash at ambient temperature, to produce a mixed rare earth carbonate
(MREC) test product.
Figure 1. The MREC produced from bench scale metallurgical test work which contains 358g/t Ga₂O₃.
Next Steps
Further MREC production
The initial MREC production undertaken by Core (Brisbane) was an ongoing program to determine
the highest recoveries of heavy rare earths especially Dysprosium (Dy) and Terbium (Tb) and wasn’t
designed to recover Gallium (Ga).
However, the preliminary results are extremely encouraging and position Victory with the
opportunity to become one of the first mining companies to produce a MREC containing Gallium as
a high-value by-product, with significant opportunity to further enhance Gallium recovery within
the MREC.
To advance this potential, Victory has appointed ALS Metallurgy in Perth to undertake bulk MREC
test work. This next phase will focus on optimising the recovery conditions for Gallium Oxide

product.
Upgraded Mineral Resource Estimate
MEC Mining a global mining resource firm based in Western Australia who were responsible for
delivering Victory’s January 2025 MRE have been commissioned to include Ga₂O₃ in an updated
resource.
Victory believes this upgrade to the MRE to incorporate Gallium will demonstrate to the market the
scale of Gallium through the North Stanmore system.
It is proposed the update to the MRE will take up to 4 weeks. After the release of the updated MRE,
it is anticipated that Victory will update the recently announced Scoping Study to incorporate Ga₂O₃
and any other exploration results from the drilling program which is currently underway.

•
A reputable commercial transport company was used to transport the bags.
•
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

•
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

•
(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, causing Less
chance of cross-contamination.
•
(AC) drill rigs are lighter in weight than other rigs, meaning they are quicker
and more manoeuvrable in the bush.
•
(AC) Drilling was performed 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 regularly inspected by VTM personnel and contract staff.
The drill rig with automatic rod handlers, with fire and dust suppression
systems, mobile and radio communications, qualified and ticketed safety
trained operators and offsiders, are required by Victory's work health and
safety systems.
•
The majority of samples were dry and sample recovery was variable, where
excessive water flows were encountered during drilling.
•
Representative percussion drilhole samples were collected as 1-meter
intervals, with corresponding chips placed into chip trays and kept for
reference at VTM’s facilities.
•
Measures taken to ensure sample representivity and recovery 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.
•
All percussion samples in the chip trays were lithologically logged using
standard industry logging software on a notebook computer.
•
All (AC) samples have been logged for lithology, alteration, quartz veins,
colour, fabrics.
•
All (AC) samples have been analysed by a handheld pXRF.

The overall performance of the blanks was deemed to be acceptable, see.
•
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 CP’s.
•
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.

The use of twinned holes.
•
Eleven percussion (air core and RC) drillholes have been twinned with
diamond drilling (DD001 to DD011). Samples were submitted to the
laboratory for analysis only if the initial screening by handheld pXRF satisfied
the anomalous value threshold as set by company policy, whereas the
diamond drilling was sampled and assayed along the entire length of the
drillhole.
•
QQ plots were prepared between the percussion and diamond assays paired
at 5m, with good correlation between the two drillhole types.

51% of the drillholes were surveyed by RTK/DGPS. The 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. Drill holes were both vertical
(92%) and inclined (8%). The majority of drill intervals (99%) were less than a
drill hole depth of 100m.

•
A three second SRTM Digital Elevation Model was used to represent the
topographical surface sourced from Geoscience Australia. The topography
was adjusted by using the DGPS surveyed collar coordinates to model a more
accurate topographical surface. It is recommended that a LiDAR based DEM is
used in future.
