Graphite Bull & Narryer Projects: Exploration Update
•
Core drilling completed for 1221.5 m in two holes
•
RC drilling ongoing 3,534m (9-22 Aug) at 246 metres per day
•
All holes intersect graphite inc. 68 metres @ >10% visually estimated TGC
•
Product qualification commenced with BTR in China
•
RC drilling to commence at the Narryer Project
Buxton Resources Ltd (‘Buxton’; ASX:BUX) is pleased update shareholders in relation
to activities at the 100% owned Graphite Bull and Narryer Projects. The ongoing
drilling program at Graphite Bull aims to support a substantial Mineral Resource
Estimate in Q4 2024. Recent drilling-related activities include;
-
Diamond drilling (DD), completed 8th August with a total of 1,221.5 metres of
HQ diamond core drilled across two holes.
-
An initial batch of 57 samples from a ~52 metre length of diamond core
(GB006DD 491.00 – 541.96 metres) is currently at ALS laboratories and has
completed sample preparation. Total Graphitic Carbon (TGC) results are
expected within two weeks.
-
Reverse Circulation (RC) drilling has progressed smoothly, with 3,534 metres
drilled across 24 holes (GB008RC – GB031RC – Table 3) averaging 146 metres
depth, at 246 metres per day. Most holes have been drilled across 1,080
metres of geological strike East of the existing Resource area (Figure 1).
Several new RC holes within the existing Resource aim to provide support for
conversion to JORC Indicated classification.
-
The RC drilling has intersected graphite mineralisation > 5% visually estimated
TGC within 832 metres, or 24% of the metres drilled (Table 1). Results include
68 metres at >10% visually estimated TGC from 43 metres in GB012RC (see
table inset on Figure 1). These new results are highly encouraging given that
the 2011-2012 programs, which were drilled to the South (generally
subparallel with ore zones), achieved an equivalent rate of 25% (1050.7 metres
>5% TGC assayed across 4,149.7 metres of drilling). The current program is
drilled mostly North with the aim of intersecting ore zones at an angle closer
to true width. This result is interpreted to reflect generally thicker true widths
of mineralisation in the East compared to the Resource area.

The first batch of RC samples is expected to be delivered to ALS laboratories
in Perth on 26th August, results expected within 1-2 months. Full assays to
support mineral resource estimate are expected to take 2-3 months to
complete.
A substantively increased Mineral Resource Estimate is now targeted based on
results from the 2023 & 2024 drill programs (>5,000m RC) supported by improved
confidence in geological continuity provided by results from diamond drilling and
recent structural mapping. Drilling activities will be finalised over the coming days.

existing Resource zones (steeply dipping to the South) are also shown. The table inset shows the top
six intersections at >10% visually estimated TGC (true widths not determined).
Cautionary Statement: Visual estimates of mineral abundance should never be considered a proxy
or substitute for laboratory analyses where concentrations or grades are the factor of principal
economic interest. Visual estimates also potentially provide no information regarding impurities or
deleterious physical properties relevant to valuations.

In addition to the ongoing drilling programs at Graphite Bull, Buxton has recently
dispatched a 1.5 kg parcel of graphite flake concentrate to BTR New Material Group,
to commence qualification testwork. The concentrate was prepared by at ALS
Metallurgy to a >95% TGC specification. BTR has held the top global market share
for anode materials for 14 years, serving major lithium-ion battery manufacturers such
as Panasonic, Samsung SDI, LGES, SKOn, CATL, and BYD. 1
The Topdrill RC rig will move to the Narryer Project over the weekend to test the
800 m x 150 m Ranger EM target (6,000 Seimens – Figure 2). This program will
consist of 1-2 holes, with capacity for further drilling if warranted.

About the Graphite Bull Project
The at-surface, high-grade Graphite Bull (formerly Yalbra) Project is in the Tier 1 mining jurisdiction of
Western Australia, Gascoyne region, on granted Exploration License E09/1985. Graphite Bull was
acquired by Buxton in 2012 and by 2014 an airborne EM survey, several drilling programs and two
resource estimates were completed. The Graphite Bull project currently has a JORC (2012) compliant
Inferred Resource of 4 Mt @ 16.2 % TGC (ASX 24/10/2014).
Due to projected growth of the global Lithium-ion battery market, and the essential part graphite will
play in that – graphite is the single largest component of Li-ion batteries – Buxton recommenced work
at Graphite Bull in 2022. Work since then has been focused on metallurgical test work through to final
product (Activated Anode Material), and increasing Resource confidence and size, with very promising
results to date.
Forecast battery-related demand (Benchmark Mineral Intelligence) means that by 2027, global
graphite production needs to double and that, by 2040, eight times current production will be
required to supply the world’s lithium-ion battery anode market. Non-China battery anode capacity,
and investment, is being spurred by US IRA legislation. Graphite Bull is therefore a very attractive
project, being a high-grade deposit located in a Tier 1, US FTA mining jurisdiction, with ore materials
having demonstrated excellent electrochemical performance and with outstanding Resource growth
potential.
Figure 3: Buxton’s Graphite Bull & Narryer Projects are located within the Gascoyne / Murchison
Region of Western Australia.

About the Narryer Project
The Narryer Terrane forms part of the Archean Yilgarn Craton margin which hosts the recently
discovered, world-class Julimar Ni-Cu-PGE Project. This new discovery by Chalice Mining Ltd and the
presence of numerous Ni-Cu-PGE occurrences along a >1,000km strike length defines the West
Yilgarn Ni-Cu-PGE Province - a highly prospective new exploration frontier now subject to intense
exploration activity. Buxton has also now identified that the Narryer Project has potential for
carbonatite-related Rare Earth Element (REE) style deposits in the Proterozoic Badgeradda Basin
rocks which have been accreted to the Yilgarn Craton. The Narryer Project also has potential for
regolith-hosted REE within both Proterozoic and Archean successions.
With the granting of E09/2722, Buxton now holds 1,918 km2 in four granted ELs along the highly
prospective Yilgarn Western Margin, including the adjoining ~30 km long tectonic sliver of the
Proterozoic Badgeradda Basin which has been emplaced here along this craton margin.
During 2021 & 2022, Buxton completed ground reconnaissance, a regionally extensive 1-km spaced
ground gravity survey and a highly targeted 2566.6-line km Airborne EM survey. Interpretation of the
AEM data has identified multiple high priority anomalies, three of which warranted immediate followup by moving loop EM, which was completed at Bandito, Prodigy and Ranger Prospects in early 2023.
Additional soil sampling was conducted over AEM targets in late 2003 which provided
encouragement to extend the Ranger ground EM coverage.
In additional to well defined Ni-Cu-PGE prospectivity, the broad tectonic and geological setting is
prospective for REE, with the Gascoyne region shaping up as next Australia’s REE hotspot. REE
projects nearby include Yangibana (under construction, ASX: HAS), Mangaroon (ASX: DRE), Mick Well
(ASX: KFM), and Innouendy (ASX: DM1). The only REE operation in production in Australia is Mount
Weld (ASX: LYC), near Laverton, WA.

JORC Table: Section 1 – Sampling Techniques and Data
Criteria
JORC Code explanation
Commentary
Sampling techniques
Nature and quality of sampling (eg cut channels, random
chips, or specific specialised industry standard
measurement tools appropriate to the minerals under
investigation, such as down-hole gamma sondes, or
handheld XRF instruments, etc). These examples should
not be taken as limiting the broad meaning of sampling.
Include reference to measures taken to ensure sample
representivity and the appropriate calibration of any
measurement tools or systems used.
Aspects of the determination of mineralisation that are
Material to the Public Report. In cases where ‘industry
standard’ work has been done this would be relatively
simple (e.g. ‘reverse circulation drilling was used to
obtain 1 m samples from which 3 kg was pulverised to
produce a 30 g charge for fire assay’). In other cases,
more explanation may be required, such as where there is
coarse gold that has inherent sampling problems.
Unusual commodities or mineralisation types (e.g.
submarine nodules) may warrant disclosure of detailed
information.
Drill type (e.g., core, reverse circulation, open-hole
hammer, rotary air blast, auger, Bangka, sonic, etc) and
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).
Diamond drilling at Graphite Bull produced HQ diameter
core (63.5mm diameter). All core runs are oriented
using an Axis Mining Technology Champ Ori tool.
Method of recording and assessing core and chip sample
recoveries and results assessed.
Measures taken to maximise sample recovery and ensure
representative nature of the samples.
Sample recovery for DD core loss is recorded by the
drillers with any core loss intervals noted on annotated
wooden blocks inserted into the core boxes by the
driller. Core loss averages 99.5% for the hole. No
significant core loss is recorded in the reported
mineralised intervals.
Drilling techniques
Drill sample recovery
Whether a relationship exists between sample recovery
and grade and whether sample bias may have occurred
due to preferential loss/gain of fine/coarse material.
Analyses will be undertaken by ALS Geochemistry in
Perth and include Total Graphitic Carbon with other
parameters as necessary.
Diamond drilling (DD) and Reverse Circulation (RC)
drilling was undertaken by by Topdrill PL using a Sandvik
DE880 trick mounted rig (DD) and a Schroamm T685
truck mounted rig (RC).
Rod counts are routinely carried out and marked on the
core blocks by the drillers to ensure the marked core
block depths are accurate.
RC recoveries were considered good with available air
for drill sample recovery being deemed adequate for the
ground conditions and depth of sampling undertaken.
Appropriate measures have been undertaken to
maximise sample recovery and ensure the
representative nature of samples, including:
-
Terminating RC holes when recovery amounts
are reduced at depth
Terminating RC holes when excess water is
encountered
Full assessment of recovery will be undertaken when the
core is transported to BUX’s core processing facility in
Perth, with QA/QC of the recovery to be assessed by
reconstructing the core into continuous runs in an angle
iron cradle.
No apparent relationship has been defined between
sample recovery and grade based on the various drilling
programs to date at Graphite Bull.

Logging
Whether core and chip samples have been geologically
and geotechnically logged to a level of detail to support
appropriate Mineral Resource estimation, mining studies
and metallurgical studies.
Whether logging is qualitative or quantitative in nature.
Core (or costean, channel, etc) photography.
The total length and percentage of the relevant
intersections logged.
Diamond Drilling
Logging of the diamond drill hole was conducted at the
Project site by qualified geologists with sufficient
knowledge of the deposit style and the geological
terrane the drilling was completed in.
Logging of the hole is ongoing with lithology, mineralogy
and mineralisation being recorded digitally.
Logging completed can be considered qualitative in
nature.
Once the core is transported to BUX’s core processing
facility in Perth, further qualitative logging of the entire
hole will be undertaken recording weathering, colour,
and other features of the samples.
In addition to the qualitative logging, once the hole has
been transferred to BUX’s core processing facility in
Broome the core will be logged in a quantitative manner
in terms of structure and geotechnical parameters.
Photographs of all DD trays will be taken at BUX’s core
processing facility at the Project, and in Perth and
retained on file with the original core trays stored at
BUX’s core library in Peth.
Logging to date can be considered sufficient to report
the intersection of low grade (trace-5% TGC), moderate
(5-10%) and high-grade (>10% TGC) graphite
mineralisation based on visually estimates and with
reference to previous drillhole samples and results.
Logging to be completed at BUX’s core processing facility
in Perth will be adequate to support downstream
exploration studies and follow-up drilling.
Reverse Circulation Drilling
For the RC program, chip trays were collected from each
one metre interval this was used to log lithology,
oxidation and visual graphite content estimate a streak
test was used to assist with visual estimates alongside
historical samples.
Visual estimates for TGC were based on comparison with
historic samples from Buxton’s 2014 program, YBRC0018
and YBRC0019 which constituted 276 metres of
previously assayed material with grades from 0.1% to
30.9% TGC. This included 52 samples greater than 10%
TGC. 19 samples from 5-10% and 87 samples from 0-5%.
Samples were noted if they were wet or where recovery
was significantly impacted.
Photographs of all RC chip trays will be taken at BUX’s
core processing facility at the Project, and in Perth and
retained on file with the original chip trays stored at
BUX’s storage facility in Peth.

For all sample types, the nature, quality and
appropriateness of the sample preparation technique.
Quality control procedures adopted for all sub-sampling
stages to maximise representivity of samples.
Measures taken to ensure that the sampling is
representative of the in-situ material collected, including
for instance results for field duplicate/second-half
sampling.
Whether sample sizes are appropriate to the grain size of
the material being sampled.

All samples to be submitted for assay will be selected
from the same side of the core, with exceptions only
being for duplicate samples of selected intervals, where
quarter-core subsamples will be cut from the half-core.
Reverse Circulation Drilling
All RC one-metre sub-samples from drill holes were
collected from a cone splitter respectively, to produce an
~15% routine split sample for analysis.
The nature, quality and appropriateness of the assaying
and laboratory procedures used and whether the
technique is considered partial or total.
Not applicable, the release does not include laboratory
assay results.
For geophysical tools, spectrometers, handheld XRF
instruments, etc, the parameters used in determining the
analysis including instrument make and model, reading
times, calibrations factors applied and their derivation,
etc.
Nature of quality control procedures adopted (eg
standards, blanks, duplicates, external laboratory checks)
and whether acceptable levels of accuracy (ie lack of bias)
and precision have been established.
Not applicable, the release does not include data from
geophysical or handheld XRF tools.
The verification of significant intersections by either
independent or alternative company personnel.
Senior company geological personnel onsite for the
entirety of the drilling and logging process.
In addition to duplicate samples (detailed above),
Quality Control and Quality Assurance (QA/QC)
procedures included insertion of standards (three
different standards each certified for TGC at three
different abundance levels appropriate for the Graphite
Bull mineralisation) and blanks which were inserted
every 20 samples.
Once the core is processed at BUX’s core processing
facility in Perth. The logging will be validated by a BUX
on-site geologist and compiled onto the BUX MX Deposit
drill hole database
Assay data will be imported directly from digital assay
files from contract analytical company ALS (Perth) and
merged in the Company MX Deposit drill hole database.
Data is backed up regularly in off-site secure servers.
