ENCOURAGING ORE SORTING RESULTS HIGHLIGHT POTENTIAL FOR
LOW-COST UPGRADING AT HIGH-GRADE QUINN FLUORSPAR

• Early waste rejection has the potential to increase CaF₂ feed grade while reducing tonnes reporting
to downstream processing, potentially reducing:
o grinding and milling power requirements
o grinding media and equipment wear
o flotation reagent consumption
o water consumption
o tailings generation
• Big Jim is particularly exceptional, with the main-vein sample returning 98.3% CaF₂ by head assay and
98.6% fluorite by QXRD before beneficiation, already exceeding the typical CaFâ‚‚ grade requirement
for Acidspar. Further product-quality testing is required to determine whether a directly saleable
product can be produced
• Core Resources' comprehensive metallurgical program is progressing to plan, integrating
mineralogy, size-by-assay, grind optimisation, Heavy Media Separation (HMS), rougher and cleaner
flotation and impurity characterisation
• Following the encouraging TOMRA sighter results, OD6 intends to progress larger-scale ore-sorting
trials using approximately 500-1,000 kg bulk samples to establish quantitative mass rejection, grade
uplift and recovery performance
Managing Director Brett Hazelden, commented:
“These results are exciting not simply because of the exceptional grades, but because they are beginning to show us
how the different mineralisation styles at Quinn could potentially be mined and processed.
We deliberately did not just send TOMRA and Core our best-looking fluorspar. We selected discrete samples
representing high and medium-grade mineralisation together with hanging-wall, footwall and internal waste so
that we could understand how mining dilution may behave and, importantly, whether it can be removed before
milling. At Blue Bell, Big Jim and Horseshoe, TOMRA has demonstrated very clear discrimination between these
material types. This potentially gives us the ability to reject waste at a coarse crush size, upgrade selected material
towards a Metspar product and substantially reduce the tonnes that ultimately need to be ground and floated to
produce higher-value Acidspar.
The head grades themselves are exceptional. Big Jim returned 98.3% CaFâ‚‚, Horseshoe 90.0% CaFâ‚‚ and Blue Bell
86.7% CaFâ‚‚, with independent QXRD mineralogy confirming these samples are overwhelmingly comprised of
fluorite with relatively simple gangue mineralogy.
We are particularly encouraged by Big Jim, where the main-vein sample is already above the typical CaFâ‚‚ grade
required for Acidspar before beneficiation. At Horseshoe and Blue Bell, the combination of naturally high grades,
low impurities and strong ore-sorting discrimination creates significant optionality for both Metspar and Acidspar
production routes.
The Core Resources programme is progressing to plan and will now take these same representative material types
through grind optimisation, HMS and flotation. Combined with larger-scale TOMRA sorting trials, this work will
allow us to develop an integrated processing flowsheet specifically designed around the different mineralisation
domains at Quinn.
With the USA importing 100% of its fluorspar and classifying it as a critical mineral, a clean, high-grade Nevada
source is exactly what the US supply chain, including the US military, are looking for.”

Quinn Metallurgical Development Test Work Program
OD6 Metals Limited (ASX: OD6) ("OD6" or "the Company") is pleased to report highly encouraging head
assay, mineralogical and preliminary sensor-based ore sorting results from its ongoing metallurgical
development program for the Quinn Fluorspar Project in Nevada, USA.
The results represent an important step in the systematic development of the Quinn processing strategy and
follow the Company's previously announced review of historic metallurgical testwork, which demonstrated the
potential to produce both metallurgical-grade fluorspar (Metspar) and acid-grade fluorspar (Acidspar) products
from Quinn mineralisation.
The current program combines modern mineralogical characterisation and conventional beneficiation studies
being undertaken by Core Resources in Brisbane with sensor-based ore sorting investigations undertaken by
global sorting technology company TOMRA at its Test Centre in Wedel, Germany.
Preliminary characterization work has been received and is presented in this release. This on-going work will
involve milling and flotation tests to achieve the targeted Metspar (>60% CaF2) and Acidspar (>97% CaF2)
products.
Metallurgical Samples Designed to Test Mining Dilution and Processing Response
A total of approximately 166 kg across 11 large-format samples from Mammoth, Blue Bell, Horseshoe and Big
Jim was delivered for the metallurgical program, with individual samples ranging from approximately 8 to 25 kg.
These large format samples were collected and composited from different localities within four projects
(Horseshoe, Big Jim, Blue Bell and Mammoth) to build a representivity of typical ore types as well as waste rock
and mixed waste/ore as exposed at surface at the Quinn Project.
Importantly, the metallurgical sampling program was not designed to preferentially select only high-grade
fluorspar. OD6 deliberately collected discrete samples representing the principal geological and potential
mining domains observed at each deposit, including:
• high-grade mineralisation
• medium and lower-grade mineralisation
• mixed ore and host rock
• breccia mineralisation (broken or fragment mineral and rocks cemented together in a matrix)
• footwall material
• hanging-wall material
• internal waste/host rock
The objective is to understand how each material type may behave during future mining and processing and, in
particular, assess the potential impact of mining dilution.
The same discrete material types form the basis of the TOMRA ore-sorting investigation and Core Resources
beneficiation program, allowing the Company to evaluate the potential processing pathway for each
mineralisation and waste domain.
The inclusion of deliberately low-grade and barren samples is therefore an important part of the program.
For example, Blue Bell samples range from 86.7% CaFâ‚‚ in the main vein to 0.4% CaFâ‚‚ in hanging-wall
volcanic waste, providing strongly contrasting end-members against which sensor-based sorting can be
evaluated. Horseshoe similarly includes high-grade mineralisation together with approximately 7.4% CaFâ‚‚
4
host/internal limestone, while Big Jim includes the exceptionally high-grade main vein and lower-grade
footwall breccia.
This approach provides a more realistic basis for evaluating future mining dilution and the ability to reject waste
before downstream processing.
TOMRA Preliminary Ore Sorting Summary Results
OD6 Metals has joined with TOMRA, a world-leading sorting sensor company with a test centre in Germany and
offices in Australia, to conduct preliminary sighter tests on product from the metallurgical samples. TOMRA XRT
technology is currently utilised to help remove waste from feed at the Las Cuevas fluorspar mine in Mexico
TOMRA were presented with coarse (5 to 12mm) representative samples from the metallurgical samples.
The samples were evaluated using:
Laser sorting – which evaluates differences in surface properties, colour, brightness and crystalline
characteristics; and
X-Ray Transmission (XRT) – which differentiates particles according to differences in atomic density.
The preliminary investigation successfully demonstrated the ability to distinguish fluorite-rich material from
lower-grade and waste material.
At Horseshoe, Laser sorting demonstrated clear differentiation between the two styles of high-grade fluorspar
and the limestone host/internal dilution material.
At Big Jim, both Laser and XRT clearly differentiated the massive high-grade fluorspar vein from footwall and
hanging-wall material.
At Blue Bell, the volcanic host rock provided particularly strong contrast to the fluorspar veins, with both Laser
and XRT demonstrating clear differentiation between the ore and waste domains. The results indicate that even
lower-grade fluorspar-bearing footwall material may potentially be amenable to upgrading through ore sorting.
At Mammoth, preliminary sorting was less definitive due to similarities between crystalline quartz and fluorite-
bearing material. Mammoth remains primarily a bulk-tonnage beneficiation target, with HMS and flotation
investigations forming an important component of the ongoing Core Metallurgy program.
Preliminary characterization work has been received and is presented in this release from the four projects
(Horseshoe, Big Jim, Blue Bell and Mammoth).

Acidspar and Metspar
Fluorspar (also known as fluorite) is a simple mineral with the formula CaF2, which contains 48.9% fluorine by
weight. Fluorspar is the main mineralogical source of fluorine. High-grade fluorspar mineralisation is typically
upgraded through simple processing to produce concentrates known as Metspar and Acidspar.
MetSpar is a mineral product containing >60% fluorspar (CaF2) and is sold to the steel industries as a fluxing
agent. As a fluxing agent, the MetSpar improves slag fluidity, remove impurities, lower the melting temperature,
protects refractory materials and is used to enhance high-end stainless steel products.
MetSpar typical needs to be:
• >60% CaF2
• less than 5,000ppm lead (Pb)
• less than 3,000ppm sulphur (S)
AcidSpar is an upgraded mineral product containing >97% fluorspar (CaF2) and is sold to the chemical industry
for hydrofluoric acid production, and ultimately is used in the nuclear fuels industry, battery technologies, solar
panels, defence technologies and AI chip manufacturing.
AcidSpar specifications typically need to be:
• >97% CaF2
• <1.5% silica (SiO2),
• <10-20ppm arsenic,
• <1,000ppm sulphur (S)
• <100-550ppm phosphorous (P).
• Penalties or refusal are potentially applied for high lead (Pb) and other base-metals (Cu, Zn, Mo), and
pollutants such cadmium, chromium or any radioactive elements such as uranium or thorium.
Why Ore Sorting could be Important for Quinn
Sensor-based ore sorting can potentially be positioned immediately following primary/coarse crushing to
produce a Metspar product or before energy intensive grinding and flotation, to produce a Acidspar product
Metspar generally requires substantially less beneficiation than Acidspar. Selected high-grade Quinn material
may therefore have the potential to be crushed, sorted and sized to produce a coarse Metspar product without
requiring the entire material stream to undergo fine grinding and flotation.
The conceptual processing sequence Metspar becomes:
ROM Ore → Crushing → Sensor-based Sorting → Waste Rejection / Potential Coarse Product → Metspar
This could potentially provide:
• a relatively simple processing route
• lower power requirements
• reduced water demand
• reduced capital intensity
• greater flexibility between Metspar and future Acidspar production
6
The conceptual processing sequence Acidspar becomes:
ROM Ore → Crushing → Sensor-based Sorting → Waste Rejection / Potential Coarse Product → Grinding
→ Flotation → Acidspar
Rather than processing all mined material through the milling and flotation circuit, sensor sorting potentially
allows barren or low-grade mining dilution to be rejected at a relatively coarse particle size.
This could provide a number of material benefits to a future Quinn development, including early waste rejection
that has the potential to increase CaFâ‚‚ feed grade while reducing tonnes reporting to downstream
processing, potentially reducing:
• grinding and milling power requirements
• grinding media and equipment wear
• flotation reagent consumption
• water consumption
• tailings generation
QXRD Preliminary Ore Sorting Results
Core Resources has conducted independent quantitative x-ray diffraction (QXRD) studies on the mineralogy of
samples, with analysis providing strong corroboration of the exceptional fluorite content of the high-grade
samples.
Importantly these works show no other fluorine bearing minerals other than fluorspar, with coarse quartz, calcite
and minor clays as the principal gangue minerals. Quartz and calcite can potentially be removed using ore-
sorting and flotation.
This relatively simple mineralogy is encouraging for beneficiation because the principal gangue minerals are well
understood and can be targeted through ore sorting, density separation and/or flotation.
QXRD is a mineralogical technique and should not be interpreted as replacing quantitative chemical assay. Its
close correlation with the head assay results nevertheless provides valuable independent mineralogical support
for the exceptionally high fluorite content observed.
Results are presented in this release from the four projects (Horseshoe, Big Jim, Blue Bell and Mammoth).
Very Low Impurity Levels
Multi-element characterisation of the metallurgical samples has also returned very low concentrations of a range
of potentially deleterious elements within the high-grade fluorspar material.
Arsenic, cadmium, base-metals, sulphur and uranium achieve metspar and acidspar requirements even before
upgrade, providing encouraging characteristics for production of Metspar and, subject to product-quality
testwork, potentially Acidspar
The combination of high CaFâ‚‚ grades, relatively simple gangue mineralogy and low concentrations of potentially
deleterious elements is encouraging for the production of clean fluorspar concentrates.
Detailed product-quality assessment will form part of the ongoing metallurgical program.
Results are presented in this release from the four projects (Horseshoe, Big Jim, Blue Bell and Mammoth).

HORSESHOE SPECIFICATIONS AND RESULTS
• 90% CaF2 (fluorspar) assay for raccoon tail textured fluorspar type (90.4% on mineralogy QXRD test)
• 76.2% CaF2 assay for fluorspar breccia type (79.3% on mineralogy XRD test)
• 7.4% CaF2 assay for country rock limestone (with veins of fluorspar) (7.8% on mineralogy QXRD test)
• Gangue minerals (from mineralogical studies on ore) consist only of quartz (7.3% to 9%), kaolinite (1.3 to
1.4%) and calcite (0.9 to 10.3%) indicating the potential for flotation of a very clean final product
• Very low deleterious elements
The Horseshoe Deposit is a replacement style epithermal fluorspar deposit exposed over approximately 3000
square metre zone (~60m x 50m) and extends up-dip into the hill and down-dip beneath talus slope cover. The
thickness of this shallowly dipping body, as estimated from historic drilling and geological mapping, is 20 to
30m, with a footwall mixed limestone-fluorspar breccia of unknown thickness adding the potential for an
increase of this width. Channel sampling has revealed spectacular grades and with spectacular grades and width
including 50m @ 63.9% CaF2 and 15m @ 75.8% CaF2 (refer ASX announcements 4 March 2026, 15 April 2026, 8
July 2026).
Three large format samples were collected and sent to Brisbane for this test work. These included:
1. Horseshoe Met #1: the raccoon tail textured fluorspar from several sites within the historic open pit
2. Horseshoe Met #2: brecciated fluorspar from several sites within the historic open pit.
3. Horseshoe Met #3: from a limestone host, including rafts of limestone ~2m thick from within the historic
open pit.
Horseshoe Met #1 and Horseshoe Met #2 showed higher grades than previous channel sampling in these area s
with assays of 90.4% CaF2 (Horseshoe Met #1) and 76.7% CaF2 (Horseshoe Met #2). Furthermore, the host rock
limestone returned an assay of 7.4% CaF2, indicating low-grade halo and will perhaps reduce the risk of dilution
from over-break when mining.
Multi-element analysis shows very low deleterious elements as noted in Table 1 and Table 2 below. Quantitative
X-Ray Diffraction (QXRD) analysis of minerals show that the samples are dominated by fluorspar with quartz,
calcite and minor clay minerals (kaolinite) present. This provides the potential for a very clean product with the
high-grade ore already exceeding metspar requirements, and a low-upgrade ratio to achieve an acidspar
product.
The ore-sorting work showed clear differentiation between two different styles of high-grade material, and the
country rock.

BIG JIM SPECIFICATIONS AND RESULTS
• 98.3% CaF2 assay for massive fluorspar vein (>2m thick) (98.6% on mineralogy QXRD test)
• 27.8% CaF2 assay for footwall breccia with mixed fluorspar and limestone (35% on mineralogy QXRD
test)
• Gangue minerals in the high-grade vein consist of 0.1% quartz, 0.4% calcite and 0.9% kaolinite
• Gangue minerals in the fluorspar matrix of the footwall breccia consist of 61.1% quartz, 0.1% calcite,
3.7% kaolinite
• Very low deleterious elements
The Big Jim target is a high grade shallow dipping vein approximately 2m thick. It is exposed in historic workings
over an outcrop of several metres, though historic mine plans indicate a strike length of approximately 230m.
The hanging wall of the main vein consists of a silicified jasperoid body, which marks the Saw Mill Thrust. The
footwall consists of a fluorspar matrix breccia with large clasts of limestone/dolomite (refer asx announcement
12 May 2026)
Two large format samples were collected and sent to Brisbane for this test work. These included:
1. Big Jim Met #1: the massive fluorspar vein
2. Big Jim Met #2: brecciated fluorspar / limestone from the footwall.
The grades returned from the main vein corroborate the historic reports (up to 98.6% CaF2). The footwall sample
was lower grade than the historic work, though this may have been biased to the limestone clasts. A sample of
the hanging wall was not taken for metallurgical testwork as the contact with the main vein is very sharp (the
jasperoid acting as an impervious aquitard) and no fluorspar was observed. However, a sample of the hanging
wall was included in the ore-sorting test (Big Jim Met 3).
Multi-element analysis shows very low deleterious elements as noted in Table 1 and Table 2 below. Quantitative
X-Ray Diffraction (QXRD) analysis of minerals show that the samples are dominated by fluorspar with quartz,
calcite and minor clay minerals (kaolinite) present.
The ore-sorting work showed clear differentiation between the main vein, the limestone in the footwall vein and
the hanging wall vein. Further product-quality testing is required to determine whether a directly saleable
product can be produced

BLUE BELL SPECIFICATIONS AND RESULTS
• 86.7% CaF2 assay for massive fluorspar vein (1 to 2m thick) exposed in historic pit (91.6% on
mineralogy from QXRD tests)
• 9.9% CaF2 assay for footwall fluorspar in stockwork zone hosted in volcanics (11.4% on mineralogy
from QXRD test)
• 0.4% CaF2 assay from hanging wall volcanic waste
• Gangue minerals in the high-grade vein are 7.5% quartz, 0.6% calcite with minor clays.
• Gangue minerals in the footwall volcanics include 60.6% quartz, 21.8% feldspar and minor clays
• Very low deleterious elements
The Blue Bell Project was recently staked by the Company and has been visited to collect metallurgical samples.
Channel samples have also been collected and are pending assay. The project consists of a 1 to 2m high-grade
vein which dips steeply to the north and which outcrops in an historic open pit over 60m strike. The footwall
consists of stockwork fluorspar veins in a volcanic host with a zone with a width of 12 to 20 metres. The
mineralized zone is open along strike to the west (refer ASX announcement 23 June 2026)
Three large format samples were collected and sent to Brisbane for this test work. These included:
3. Blue Bell Met #1: the massive fluorspar vein
4. Blue Bell Met #2: stock fluorspar veins hosted in volcanics from the footwall
5. Blue Bell Met #3: hanging wall unmineralized volcanics
The grades returned from the main vein corroborate the historic reports of grade from Blue Bell.
Multi-element analysis shows very low deleterious elements as noted in Table 1 and Table 2 below. Quantitative
X-Ray Diffraction (QXRD) analysis of minerals show that the samples are dominated by fluorspar with quartz,
calcite and minor clay minerals (kaolinite) present. The volcanics consist of quartz and feldspar.
The ore-sorting work at Blue Bell showed perhaps the strongest and easiest project to ore-sort. The volcanics
clearly differentiate from the fluorspar bearing veins in both the XRT and Laser methods. Despite the lower
grades in the footwall, this material appears to be readily upgradeable with ore-sorting technologies.

13
MAMMOTH SPECIFICATIONS AND RESULTS
• 40.4% CaF2 assay for main fluorspar breccia (48.5% on mineralogy QXRD test)
• 24.7% CaF2 for banded breccia (27.7% on mineralogy QXRD test)
• 10.9% CaF2 for mixed veins in footwall limestone (13.8% on mineralogy QXRD test)
Whilst Mammoth is a lower grade than Horseshoe, it is still considered high-grade when compared to other
deposits worldwide (refer presentation 31 July 2026).
Mammoth is a breccia body currently interpreted to be steeply dipping. The inferred footprint extends over
9000 square metres with a strike of approximately 250 metres, and with a thickness of 50 to 60 metres.
Three large format samples were collected and set to Brisbane for this test work. These included:
1. Mammoth Met #1: the main fluorspar breccia
2. Mammoth Met #2: banded breccia with quartz
3. Mammoth Met #3: footwall limestone with stock work of quartz veins
The head-assay results at Mammoth are consistent with previous channel sampling and visual observation of
fluorspar. Multi-element analysis shows very low deleterious elements as noted in Table 1 and Table 2 below.
Quantitative X-Ray Diffraction (QXRD) analysis of minerals show that the samples are dominated by fluorspar
with quartz, calcite and minor clay minerals (illite) present.
Ore sorting at Mammoth appears to have been less-effective than at Horseshoe, Big Jim and Blue Bell, with
sorting technologies not readily differentiating between crystalline quartz and fluorspar. Mammoth represents
a bulk-tonnage target for processing for flotation for acidspar products.
Core Resources Program Progressing to Plan
The comprehensive metallurgical program being undertaken by Core Resources is progressing in accordance
with the planned schedule.
The program has been specifically designed to build on historical Quinn metallurgical work while applying
modern analytical, mineralogical and beneficiation techniques to representative material from Horseshoe,
Mammoth, Blue Bell and Big Jim.
The program incorporates:
• Head characterisation
• Mineralogy and liberation
• Heavy Media Separation
• Grind Establishment
• Flotation
The current Core program schedule shows head characterisation and mineralogical activities leading into grind
establishment, HMS and rougher flotation, followed by cleaner flotation and final reporting through the second
half of 2026.
The program is ultimately intended to determine the optimum integrated flowsheet for Quinn rather than
assuming that every mineralisation type requires the same level of beneficiation.
14
Next Steps
OD6's metallurgical development program will now focus on:
1. Core Resources testwork – continue grind establishment, liberation, HMS, rougher and cleaner
flotation optimisation across representative Quinn mineralisation types.
2. Larger-scale TOMRA sorting trials – collect approximately 500–1,000 kg representative samples to
quantify:
• waste mass rejection;
• CaF₂ grade uplift;
• fluorite recovery;
• optimal crush/sort particle size; and
• potential product streams.
3. Metspar product assessment – determine whether selected high-grade sorted material can meet
relevant physical and chemical Metspar product specifications with minimal downstream processing.
4. Acidspar flotation optimisation – determine optimum grind size, reagent regime and cleaner circuit
configuration to produce >97% CaFâ‚‚ Acidspar while controlling key impurities.
5. Integrated process flowsheet – combine ore sorting, HMS, grinding and flotation results to determine
the optimum processing route for the different Quinn mineralisation domains.
6. Future development studies – incorporate the resulting metallurgical parameters into future project
engineering and economic studies.
