COPPER WOLF PROJECT – Drilling
•
Buxton’s first drillhole intersects well mineralised Cu-Mo porphyry system
•
Drilling now paused at 611.67 metres depth in altered, mineralised rock
•
First hole in 30+ years into a porphyry system discovered in the 1960s
Buxton Resources Ltd (ASX:BUX) is pumped to update shareholders that it has made a major
breakthrough at its Copper Wolf Project in Arizona. The company's first drill hole, CW0001DD,
has reached a depth of 611.67 meters and has so far intersected 81.93 metres of basement
rocks with veining, alteration, and mineralization throughout which is consistent with a
Laramide Cu-Mo porphyry system (Figure 1).
Figure 1: CW0001DD core showing mineralising quartz-pyrite-chalcopyrite-molybdenite+/-bornite sulphide vein
stockwork within strongly altered gneissic rock at 546.6m. Pervasive alteration consists of sericite-chlorite-k-feldsparsilica which is also displayed as vein selvedges around the sulphides. HQ core is 63.5mm width.
Buxton is absolutely delighted with this result, a major milestone for both Buxton, its Option
partner, IGO Limited, and the project. Drilling is currently paused for changeover to a drilling
contractor with a larger drill rig with greater technical and depth capabilities. Coring is
expected to recommence soon. The contract with the new drilling company is executed and
they are currently mobilising to site.

potassium feldspar-chlorite-sericite-silica altered schist at 562.3m.
Diamond coring from surface has penetrated the expected 543 metres of Tertiary cover to
intersect Proterozoic gneissic rocks with metagranitic dykes and Laramide porphyry dykes.
All rock units have been heavily altered and mineralised by up to six stages of quartz-sulphide
veining and accompanying disseminated style mineralisation which is evident throughout the
entire 81.93 metres of basement rocks.

CW0001DD is the first drillhole in the project area since 1993 and was sited to test around
and beneath the 1970s Utah International hole RC-UC-17 which ended in identified primary
porphyry copper-molybdenum sulphide mineralisation (Figure ).

The veining, alteration and mineralisation observed in CPW0001DD is consistent with the
Laramide Cu-Mo porphyry system as discovered by Phelps Dodge in the mid-1960s.

Alteration minerals being logged by Buxton’s geologists include potassium feldspar, silica,
sericite, chlorite, various clays, and hematite. This is consistent with observations and data
from previous work completed since discovery by Phelps Dodge in 1963. Sulphide species
and estimated abundance can be seen in Table A.

All budgeted work is 100% funded by IGO Limited, who is earning equity in the project under
an earn-in option and JV agreement (ASX 22/8/2022). IGO technical staff recently visited
Buxton’s Arizona site to view CW0001DD core.

Aside from Buxton’s 2022 airborne magnetics survey, no geophysical surveys have been
conducted in the area for 60 years. Historical drilling was widely spaced and relatively
shallow, mostly focussed on supergene blanket mineralisation.
This hole is planned to reach an initial target depth of 1,100 metres, at least 320 metres
deeper than RC-UC-17. Buxton will have the capacity to extend the hole if warranted by
encouraging geology and mineralisation.
Buxton will update shareholders as this program progresses.

About the Copper Wolf Project
The Copper Wolf Project has a number of historical resource estimates1 available that confirm the presence of a large
Laramide porphyry Cu-Mo system. ASX announcement 25 October 2021 - Copper Wolf Copper Project; Arizona
USA
Porphyry Cu-Mo mineralisation at Copper Wolf has been dated at 70.3 Ma2 (Laramide age) and is largely concealed by a post-mineral
(Tertiary) sequence of volcanic and sedimentary rocks.
The Project is located within one of the most prolifically endowed copper belts in the world, yet it has not seen any drilling since the
early 1990s. Buxton’s 2022 airborne magnetic survey was the first geophysical work undertaken since the early 1960s. Historic
exploration has consisted of relatively wide spaced drilling which focussed on significant supergene copper mineralisation located
where the NW trending Cow Creek Fault intersects Laramide hypogene porphyry style mineralisation. Buxton is targeting high
grade, underground bulk mineable copper-molybdenum mineralisation. In this context, Buxton’s exploration approach can leverage
the significant advances and ready availability of modern geophysical targeting tools and mineral systems knowledge that have been
developed since exploration in this area ceased many decades ago.
On the 4th of August 2022 Buxton and IGO Limited entered into an earn-in and joint venture agreement for the Copper Wolf Project
(Arizona, USA) then held as 100% by BUX. By that agreement, IGO has an exclusive option to earn a 51% interest in the Copper Wolf
Project tenements by incurring and sole funding A$350,000 of exploration expenditure in a 24-month period from 4/10/2022 (Stage
1 earn-in). Upon IGO incurring the A$350,000 earn-in expenditure, it may elect to strike the option and form a 51% IGO/49% BUX
unincorporated joint venture. During the earn-in period, BUX will be the project manager. IGO will be the initial manager of the
joint venture. Within 6 months of the commencement of the joint venture, IGO has the exclusive right to elect to earn a further
19% joint venture interest (to take its joint venture interest to 70%) by sole funding exploration expenditure of A$5,000,000 over 3
years (stage 2 earn-in).

JORC 2012 Table 1: 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).
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.
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.
The drill core presented and discussed herein was
obtained using diamond drilling techniques and a
reputable service provider (Godbe Drilling LLC)
using an LF90 drill rig.
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.
Drill core is logged by Company geologists with
appropriate detail to support mineral resource
estimates.

Buxton’s diamond drilling program provides highquality PQ, HQ and (potentially) NQ diameter core
samples.
Core is logged for lithological, structural,
geotechnical, and other attributes.
Selected intervals were selected for sampling and
analysis. The diamond core was cut in half along the
long axis using a diamond blade rock saw. Half-core
was sampled. The samples lengths ranged from
0.3m to 1.82m to within geological boundaries with
all samples submitted to SGS Laboratories in
Burnaby.
Diamond core was drilled from surface to the
end of the hole.
HQ diamond core diameter (shown in all photos) is
63.5mm
Drill core recoveries were routinely recorded by the
drilling contractors on core blocks are the end of
each core run. Intervals are cross-checked by the
Company’s geologists.
No material core loss is recorded in the intervals
being reported.
Insufficient data from the modern drilling program
exists to establish a relationship between sample
recovery and grade. Historical data indicates there
is no relationship between sample recovery and
grade.
Systematic geological and geotechnical logging is
being undertaken. Data collected includes:
Nature and extent of lithology.
Relationship between lithology and
mineralisation
Identification of nature and extent of
alteration and mineralisation.
Location, extent and nature of structures
such as bedding, cleavage, veins, faults
etc.

Structural data (alpha & beta) are
recorded for orientated core.
Geotechnical data such as recovery,
RQD, fracture frequency, qualitative IRS,
microfractures, veinlets and number of
defect sets may be collected.
Magnetic susceptibility recorded at 1m
intervals
Comments on estimates of the proportion of visible
sulphides (e.g. chalcopyrite):
Systematic logging of HQ diamond drill
core with an estimate of the proportion of
sulphide species present is completed on
an interval basis.
Estimates on an interval basis vary from
trace (~0.1%) to 4.5%.
This estimate is a guide only as it is
difficult to estimate accurately due to the
variable nature of the mineralisation.
Actual metal grade will be determined
using analytical method at a certified
laboratory.
The sulphide species (pyrite, chalcopyrite,
chalcocite, bornite and molybdenite) occur
as irregular blebs (~10mm diameter) in
fine (~0.1mm) to medium (~0.5mm)
disseminations, narrow stringers, irregular
vein infill, irregular to laminated, narrow
(1-10mm but up to 50mm+) pyritechalcopyrite-molybdenite veins, as well as
narrow (2-15mm) centreline quartz-pyritechalcopyrite veins.
Identification of sulphide species is
completed by or under supervision of
experienced geologists (all >15 years’
experience in sulphide systems) and
supported by a handheld portable XRF.
To assist with the selection of intervals for reporting
visual sulphidies, Buxton records visual
intersections of porphyry vein style mineralisation by
estimating for each foot of core:
1) the average width of the veins (w), and
2) the number of veins (n).
Sub-sampling
techniques and
sample preparation
If core, whether cut or sawn and whether quarter,
half or all core taken.
If non-core, whether riffled, tube sampled, rotary
split, etc and whether sampled wet or dry.
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
Quality control procedures adopted for all subsampling stages to maximise representivity of
samples.

The equation w * n / interval length yields the
volume percent of the rock that is constituted by
veins.
Drill core has been halved with a core saw; with one
half of the core sent to a laboratory for assay and
the other half retained on site in ordered core
storage trays for future reference.
If core is broken, then a representative selection of
half the core is taken.
Core is photographed wet at site prior to transport.

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.
Further sample preparation in advance of assay
(weighing, crushing, splitting, pulverising) is then
undertaken at SGS Burnaby.
Buxton retains all residual laboratory pulps in a
secure storage facility.
This procedure, including the sample sizes, meets
industry standards where 50% of the total sample
taken from the diamond core is submitted.
The sample sizes are appropriate for the style of
mineralisation encountered.
Quality of assay
data and laboratory
tests
The nature, quality and appropriateness of the
assaying and laboratory procedures used and
whether the technique is considered partial or total.
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.
The verification of significant intersections by either
independent or alternative company personnel.
Verification of
sampling and
assaying

The use of twinned holes.
Drillhole CW0001DD is located within 100m of
historic hole RC-UC-17, drilled to 774.19 m (2540
feet) and for which historical logs and assays are
available.
Documentation of primary data, data entry
procedures, data verification, data storage (physical
and electronic) protocols.
All drillhole data is entered to spread sheets by
Company personnel and validated by Company
geologists. This data is then imported into the
Leapfrog software where additional validation is
completed. Digital data is securely archived on and
off-site.
Not applicable – no assays are reported in this
announcement.
Handheld GPS (+/-5m) as well as reference to
topographical, remote sensing and known reference
points (e.g., previously surveyed holes). Previous
drill collars were pickup by licensed surveyor.
Discuss any adjustment to assay data.
Location of data
points
The retention of the remaining half-core is an
important control as it allows assay values to be
viewed against the actual geology; and, where
required, further samples may be submitted for
quality assurance. No resampling of quarter core or
duplicated samples have been completed at the
project to date.
Not applicable – no assays are reported in this

If the relationship between the drilling orientation and
the orientation of key mineralised structures is
considered to have introduced a sampling bias, this
should be assessed and reported if material.
The measures taken to ensure sample security.
The results of any audits or reviews of sampling
techniques and data.

obtaining a licence to operate in the area.
Acknowledgment and appraisal of exploration by
other parties.
The Copper Wolf project does not intersect or lie
adjacent to areas with native title interests,
historical cultural sites, wilderness or national park
and otherwise sensitive environmental settings.
The tenements are in good standing with the
Federal / State government agencies.
A summary of the history of previous exploration
activities is included in this announcement.
The Competent Person has reviewed previous
reports on drilling at the Copper Wolf Project and
confirmed in the field and from discussions with a
PD site geologist that historic drilling has been
undertaken. Practices employed appear
to have been consistent with those adopted at
other projects in North America around the
same time.
Geology
Deposit type, geological setting and style of
mineralisation.
Drill hole Information
A summary of all information material to the
understanding of the exploration results including a
tabulation of the following information for all Material
drill holes:
o easting and northing of the drill hole collar
The mineralisation at the Copper Wolf Project
comprises porphyry copper-molybdenum type, with
both hypogene (primary) and supergene
(secondary) variants. This type of mineralisation is
widely distributed in the region around the Project
Drill hole collar details and significant
intersections of mineralisation in drilling are
tabulated in this announcement.
o elevation or RL (Reduced Level – elevation above
sea level in metres) of the drill hole collar
o dip and azimuth of the hole
o down hole length and interception depth
Data aggregation
methods
PO Box 661
Nedlands WA 6009
o hole length
If the exclusion of this information is justified on the
basis that the information is not Material and this
exclusion does not detract from the understanding of
the report, the Competent Person should clearly
explain why this is the case.
In reporting Exploration Results, weighting averaging
techniques, maximum and/or minimum grade
truncations (e.g. cutting of high grades) and cut-off
grades are usually Material and should be stated.

Visual estimated intercepts have been selected to
have internally consistent grade distributions, and
these have not been aggregated.
www.buxtonresources.com.au
Where aggregate intercepts incorporate short
lengths of high grade results and longer lengths of
low grade results, the procedure used for such
aggregation should be stated and some typical
examples of such aggregations should be shown in
detail.
The assumptions used for any reporting of metal
equivalent values should be clearly stated.
Metal equivalent values have not been reported in
this Announcement.
Relationship
between
mineralisation widths
and intercept lengths
These relationships are particularly important in the
reporting of Exploration Results.
If the geometry of the mineralisation with respect to
the drill hole angle is known, its nature should be
reported.
If it is not known and only the down hole lengths are
reported, there should be a clear statement to this
effect (eg ‘down hole length, true width not known’).
All intersections of mineralisation in drill holes
reported in this announcement refer to down‐hole
thicknesses of mineralisation as, to date, Buxton
has had insufficient time to evaluate the data to
estimate true thicknesses.
Diagrams
Appropriate maps and sections (with scales) and
tabulations of intercepts should be included for any
significant discovery being reported. These should
include, but not be limited to a plan view of drill hole
collar locations and appropriate sectional views.
Where comprehensive reporting of all Exploration
Results is not practicable, representative reporting of
both low and high grades and/or widths should be
practiced to avoid misleading reporting of Exploration
Results.
Other exploration data, if meaningful and material,
should be reported including (but not limited to):
geological observations; geophysical survey results;
geochemical survey results; bulk samples – size and
method of treatment; metallurgical test results; bulk
density, groundwater, geotechnical and rock
characteristics; potential deleterious or contaminating
substances.
The nature and scale of planned further work (e.g.
tests for lateral extensions or depth extensions or
large-scale step-out drilling).
Maps and cross sections in the announcement
illustrates the proximity of CW0001DD with respect
to the closest zones of historical mineralisation
intersected in RC-UC-17.
Diagrams clearly highlighting the areas of possible
extensions, including the main geological
interpretations and future drilling areas, provided this
information is not commercially sensitive.
See diagrams in the body of the text.
