ASX Release Buxton Resources Ltd (ASX: BUX, BUXO) 09 March 2026
Centurion: Direct Evidence of Proximal Cu-Au System
• Detrital sulphide fragments confirmed with 5.6% Copper, 245 ppm Silver, and
up to 3.3 ppm Gold
• The sulphide angularity and fragmentation suggest the source is a proximal
basement high
• New age dating identifies an O’Callaghans Supersuite cluster (~630 Ma) of
highly oxidised zircons - the same magmatic event responsible for Paterson
Orogen deposits including Telfer, Winu, & Havieron.
• Au-Cu prospectivity further supported by indicator mineral chemistry
• Effective and low-cost drilling solution to test basement has been identified
Buxton Resources is pleased to announce the results from ongoing analysis of
samples from Buxton’s 2025 drillhole CN002DD. Of particular significance is the
confirmation of detrital Cu-Ag-Bi-Au bearing sulphides and highly oxidised zircons
indicating the Centurion Project hosts a fertile magmatic-hydrothermal mineral
system with links to the world-class Paterson Orogen copper-gold deposits.
Buxton Managing Director Marty Moloney commented: “Centurion now moves from
a project of possibility to a project of proof. By identifying the same ‘magmatic DNA’
shared by world-class deposits including Telfer, Winu, and Havieron, we have
validated Centurion’s potential to host a province-defining discovery. With a clear
drilling solution now in hand, we have the confidence to aggressively target the
source of these sulphides.”

Buxton cautions that 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.

New Petrological and Geochemical Results
Two heavy mineral concentrates were prepared from Buxton’s 2025 drillhole
CN002DD sample. These concentrates were submitted for integrated analysis using
LA-ICPMS for “indicator mineral” geochemical characterisation. The minerals
analysed include zircon, sulphides, garnet, apatite, iron-oxides and tourmaline. Age
dating of the zircons was also undertaken. A core sample of pebble conglomerate
from the base of CN002DD was also submitted for petrographic and micro-XRF
analysis.
In summary, the combination of detrital copper-silver-gold-bismuth bearing
sulphides, high-oxidation magmatic signatures, metal-enriched indicator minerals,
and Paterson-equivalent ages confirms that the Centurion basement possesses the
right age, the right chemistry, and the right alteration to host a major copper-gold
system.
A detailed overview of this work is provided as Appendix 1.
Refined Drilling Approach
Following a comprehensive review of local drill operator capability, Buxton has
identified a contractor with capability to drill mud rotary to depths exceeding 810
metres with a single wheeled mud/diamond drilling rig. This will provide a safe and
rapid means of penetrating the entire cover sequence, including any similarly loose
sands to those which caused CN002DD to be abandoned. This will provide a rapid
and cost-effective means to test the basement.
Next Steps
Buxton will now undertake geochemical analysis of the full cored sequence.
Additional material from the basal sequence will be submitted for specialised mineral
concentration aimed at preserving and recovering additional sulphide minerals for
further LA-ICPMS analysis.
Several geophysical surveys are planned for the upcoming field season including
passive seismic surveys (following positive results from testing conducted in
November 2025) and a ground MT survey aimed at detecting basement conductors,
along with a review of the magnetic and gravity datasets using cutting-edge
processing techniques.

Appendix 1 : Technical Detail & Indicator Mineral Geochemistry
Background
Buxton has previously reported analytical results from the 2025 diamond drill hole
CN002DD, which intersected (and was abandoned in) the basal sequence assigned
to the Elsa Sandstone immediately overlying the Centurion geophysical target.
Significant silver-dominant mineralization within this basal sequence was reported,
highlighted by a 3.9-metre interval from 805 metres depth that returned 4.06 ppm
silver (Ag). This interval also exhibited anomalous levels of critical pathfinder
elements, including copper (Cu), molybdenum (Mo), rhenium (Re), zinc (Zn), and
tungsten (W), which are geochemically diagnostic of fertile magmatic-hydrothermal
systems ASX 2 Oct 2025.
The presence of these elevated metal concentrations within the sandy matrix at the
base of the cover sequence was initially interpreted as a potential geochemical halo
or a secondary enrichment zone. However, subsequent integrated petrological and
geochemical analysis (detailed below) has confirmed that these values are at least
partly related to primary, detrital sulphide fragments—including angular
chalcopyrite—sourced from a proximal Proterozoic basement high. This confirms
that the silver and associated metals are not distal anomalies but represent the
physical erosion of a nearby mineralized system, indicating that the source of the
copper-gold mineralization is in the immediate vicinity of the drillhole.
New Analysis
This Announcement covers two areas of work on the CN002DD drill core:
1) Micro-XRF mapping (Figure 2) and petrographic analysis (Figure 3) of coarse
sandstone with a pebble conglomerate band at 799.5-799.6m depth (uncut
core photo previously reported as Fig 3 from ASX 11 Aug 2025); and
2) Preparation of a Heavy Mineral Concentrate (HMC) from the basal sands in
CN002DD from which two rounds of Laser Ablation Inductively Coupled
Plasma Mass Spectrometry (LA-ICPMS) geochemical analysis were undertaken
i. Trace element analysis of selected “indicator” minerals (Table 2).
ii. U-Pb isotopic age dating & trace element analysis of zircons (Table 3).

Several highly significant findings relate to sulphides identified in petrology and
recovered into the HMC:
• Angular Chalcopyrite: The petrographically observed chalcopyrite is clearly
angular and fragmented, implying a detrital origin (Figure 3) and minimal
transport distance. In a high-energy sedimentary environment, such minerals
are chemically and physically unstable; their preservation confirms that the
primary source of the mineralisation is the adjacent Proterozoic basement high
in the immediate vicinity of CN002DD.
• Metal Rich Sulphide: HMC sample CON1001 (805m – 808.9m) contains
primary detrital chalcopyrite + pyrite with a significant metal suite including
Cu (5.6%), Ag (245 ppm), As (2,543 ppm), Bi (442 ppm) & Au (0.54 ppm) from
sulphide spot 3-046, with up to 3.3 ppm Au in spot 3-047.
The association of Cu-Ag-Bi-As-Au within these sulphide grains is a diagnostic
"fingerprint" of high-temperature hydrothermal fluids, confirming that the elevated
silver in the sands (3.9m at 4.06 ppm Ag with anomalous Cu, Mo, Re, Zn and W ASX
2 Oct 2025) is not a distal secondary effect, but is at least partially hosted within
primary (hypogene) sulphide mineral fragments eroded from a local basement high.
Based on the bulk interval grade of 4.06 ppm Ag (previously reported) and the
specific sulphide mineral grade of 245 ppm Ag (reported herein), the average
abundance of silver-bearing sulphide in the interval would be approximately 1.66%
by weight. This calculated sulphide abundance is substantially higher than uXRF
mapping of the petrological sample (~0.1% combined, see Figure 2 & Table 1)
suggesting that the metal enrichment detected by partial and total leach assays
stems primarily from post-burial chemical dispersion processes (where these metals
would be hosted in soluble salts) in comparison to the mechanical dispersion
component indicated by the detrital sulphides. The fact that both effects are now
observed in this sample is consistent with proximity to the basement source of these
metals.

photo for reference. Bottom panel: Micro-XRF mineral mapping of pyrite (green) and chalcopyrite
(red) at 100um pixel resolution. See Table 1 for sulphide mineral abundance data.
The Micro-XRF mapping indicates that a substantial amount of chalcopyrite is present in the sandy
matrix as trains of particles generally <100um in size. However, only two ablatable grains were
recovered to the HMC (which was a sample from ~5m further downhole). These sulphide particles
have a low likelihood of recovery through the “mineral sand” HMC process used for LA-ICPMS analysis
reported herein (mineral sand HMC is aimed at Ti-Zr oxide recovery / characterisation).
Buxton will process remaining samples from the Elsa sandstone using a specialised concentration
protocol aimed at recovering more of these sulphide grains.
Buxton cautions that 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.

well rounded detrital tourmaline accessory grain to lower right also likely derived from a primary
crystalline basement lithology. Two additional instances of chalcopyrite were observed along the
deepest portion of the interval (inset). Chalcopyrite demonstrates angular, fragmentary, and fractured
morphologies with fragmentary fines ranging from ~20-120 µm. Chalcopyrite shows long contacts
with adjacent quartz sand grains and is therefore interpreted as a locally derived, detrital phase. Pyrite
is trace in the lithic sandstone and shows similar morphological features to chalcopyrite with maximum
observed grain sizes of 60 µm. The inset shows a second, relatively coarse, isolated chalcopyrite grain
with pervasive fragmentation and long contacts to adjacent quartz grains. Photomicrograph &

Zircon Chemistry: The "Paterson Pulse"
Age dating of zircons from the basal sandstone has identified two major pulses of
magmatic activity. While the majority are linked to the Musgrave-aged basement
(~1.2 Ga), a critical 10% cluster correlates with the O’Callaghans Supersuite (654 –
603 Ma).
This timing is identical to the formation of the world-class Telfer and Havieron
deposits on the western margin of the Canning Basin. Furthermore, these zircons
formed under highly oxidised conditions, matching the specific chemical signature
of fertile, ore-forming magmas.
• O’Callaghans Age Cluster (~630 Ma): Approximately 15% of concordant
zircons match the age of the O’Callaghans Supersuite, the same magmatic
event responsible for the giant Telfer, Winu and Havieron deposits1
.
• High Oxidation State: Application of the Loucks Oxybarometer2
to this 630
Ma population returned an average ΔFMQ of +2.46 (max +3.27, Figure 5).
This is significant because values above +1.5 are strongly associated with
fertile, copper-gold mineralising magmatic systems. High U/Th ratios (avg.
1.27) also support derivation from an oxidised, hydrothermal system.
• Fertile IOCG Signature: The Centurion O’Callaghans data exhibits a mean
Ce/Ce* of ~287 and a mean Eu/Eu* of 0.32 (peaking at 0.49). This places the
Centurion data comfortably inside the "Mineralised Hiltaba" field of Wade et
al.3
(Ce/Ce* > 100 and Eu/Eu* > 0.3) and well above their “barren” regional
thresholds.
• Musgrave Basement: The dominant zircon population (~34%) matches the
Pitjantjatjara Supersuite (~1.2 Ga). These grains show elevated U/Th ratios
(>1.2), which, given their association with Zn-rich tourmaline and high-Mn
apatite (see below) provides further evidence that the basement has
undergone significant hydrothermal metasomatism. The Pitjantjatjara
Supersuite is highly prospective for IOCG-style mineralisation4
, particularly in
the case of Centurion as it is clearly overprinted by the younger O’Callaghans
oxidized magmatic event. This multi-stage evolution provides the
prerequisites for forming large-scale mineral systems.

Figure 4: Zircon U-Pb age dates (n = 41) from samples CON1001NM and CMR0144NM (filtering for
grains with discordance between -15% and +15%)
Key Observations from the Age Distribution:
• O'Callaghans Supersuite (654 – 603 Ma): A distinct cluster is present in both samples is the
critical "Paterson-equivalent" population. Despite being a smaller percentage of the total,
these zircons are the "ore-fertility" markers given their mean ΔFMQ of +2.04 plus also their
exceptionally high Cerium anomalies (Table 3) that confirm the presence of the same aged
magmatic system that provided the hydrothermal engine for deposits like Telfer and
Havieron.
• Pitjantjatjara Supersuite (~1220 – 1150 Ma): This represents the dominant source for
CON1001NM (12 concordant grains in this window). This population anchors the sample to
the Musgrave-aged basement high identified as having a high hydrothermal overprint (high
U/Th).
• Wider Distribution: The graph also shows a broader spread of ages, typical for detrital
sediment derived from a complex Proterozoic basement, but the concentration in the two
highlighted supersuites reinforces the interpretation of a locally derived, fertile source.
Both samples capture the same dual-age magmatic story, supporting the conclusion that the entire
area around the Centurion drillhole is part of a significant, multi-stage hydrothermal province.

Figure 5: Plot comparing Loucks Oxybarometer results that highlights the significant disparity in
oxidation states between the different zircon populations at Centurion (spread of all 33 analyses
shown in grey).
Analysis of Oxidation States (ΔFMQ):
1. O'Callaghans Supersuite (603-654 Ma): This population shows the highest median and mean
oxidation state, with values peaking well above the +1.5 ΔFMQ fertility threshold. These
zircons represent the highly oxidized magmatic-hydrothermal engine linked to the Paterson-
style copper-gold mineralization event. With a median of +2.04 ΔFMQ, it sits squarely within
the peak "Fertility Window" (+1.5 to +2.5) of major IOCG deposits such as those from Gawler
Craton5
.
2. Pitjantjatjara Supersuite (1150-1220 Ma): This dominant basement population clusters around
a neutral oxidation state. While it provided a stable host and metal source, the primary
magmatism was not as inherently "fertile" as the later Neoproterozoic overprint.
3. All Centurion Data: The project-wide distribution indicates typical average redox state (~+0.4
ΔFMQ), highlighting that the O'Callaghans magmatic event represents a distinct, high-
oxidation pulse compared to the regional background.
Targeting Insight: The O'Callaghans-aged magmas at Centurion possessed the necessary oxygen
fugacity to prevent early sulfide precipitation, thereby maximizing the potential for copper and gold
transport into a hydrothermal system. This geochemical fingerprint strongly supports the prospective
nature of the O'Callaghans-aged components for Cu-Au style mineralization.

Indicator Minerals Confirm Extensive Hydrothermal System
Results from LA-ICPMS chemistry of other minerals include:
• Manganese Apatite Signature: Sample CMR0144 (444m – 450m) hosts
hydrothermal apatite with extreme manganese levels (up to 5,425 ppm Mn),
a classic "near-miss" indicator for proximal IOCG-style systems6
.
• Zinc-Tin Pathfinders: Detrital iron-rich tourmaline is also enriched in zinc (up
to 1854 ppm), manganese (up to 5880 ppm) and tin (up to 840 ppm). High
Zn and Mn in tourmaline are common "halos" around hydrothermal centres.
Such iron-rich tourmalines are often associated with the intense sodic-calcic
and iron-metasomatism that characterizes the cores of large IOCG systems.7
• Manganese-Calcium-Tin Garnet enrichment: The garnet analyses reach 19.8
wt% Mn (a spessartine component) and these garnets have highly scattered
LREE/HREE ratios. There is also a distinct population of high-calcium grains
(up to 20.9 wt% Ca). Several grains show elevated tin levels, with a peak of
15.2 ppm Sn. These Sn-rich garnets likely crystallized from, or were altered
by, highly fractionated magmatic-hydrothermal fluids, matching the Sn-Zn
signature seen in the detrital tourmalines. Metamorphic (non-prospective)
garnets from standard pelitic or granitic rocks typically contain <2 ppm Sn.
Considering the two samples, CON1001 (from the end of hole) represents a greater
concentration of "target" material (primary copper-gold ore fragments), while
CMR0144 captures the "proximal alteration" footprint (high-Mn apatite and high-Ca
garnets). In essence, the lower sediments appear sourcing from closer to the centre
of a alteration system consistent with a magmatic-hydrothermal mineralisation event.
These chemical "fingerprints" from indicator minerals cannot by themselves be
considered definitive evidence of prospectivity for any given mineral system.
However, in conjunction with the zircon, sulphide and petrographic evidence Buxton
has collected from CN002DD, the chemistry of these other minerals does provide
further support for the presence of a proximal mineralised system.
