DRILLING UPDATE DOUBLE MAGIC NI-CU PROJECT
Phase 1 drill program at Buxton’s 100% owned Double Magic Ni-Cu Project
completed.
A two week campaign of geological and geophysical
investigations will commence immediately (9 holes completed to date for
1,333m)
Maiden RC drilling results confirm the strong prospectivity of Double Magic
with all drill tested EM conductors proven to be from the occurrence of FeNi-Cu sulphide mineralisation
DMRC003 intersected 8m (down hole) of massive and matrix sulphide
grading 3.05% Ni & 1.87% Cu (previously reported on 10th August) – there
has been no follow up drilling to this drill hole yet
Of the 4 drill holes completed since DMRC003, all testing other conductors,
3 have intersected visible semi-massive, disseminated and/or
disseminated-stringer sulphides (assays awaited)
Geological and geophysical investigations to commence immediately to
target possible extensions to mineralisation intersected in DMRC003, plus
refine targeting for the Phase 2 drill program
The Company’s drill contractor and earth moving contractor
(CrossVerijmeren) have parked equipment up on site at Double Magic at no
charge to the Company
Phase 2 drill program is expected to commence within weeks, upon
approval of statutory ground disturbance applications
Double Magic Summary
Buxton Resources Limited (ASX: BUX & BUXO) advises that it has completed its maiden
(Phase 1) drill program at its 100% owned Double Magic Nickel-Copper (Ni-Cu) Project
in Western Australia. Buxton wishes to acknowledge the support and contribution from
the WA Exploration Incentive Scheme.
Since Buxton’s previous ASX release of 10th April, Buxton has completed an additional
732 metres of RC drilling from 4 holes at the Double Magic Project. Three of these holes
intersected visible semi-massive, disseminated and/or disseminated-stringer sulphides.
Assays for all holes, apart from the previously prioritized and reported assays from drill
hole DMRC003, are awaited and expected in the coming weeks (see Table 1 below for
further information on significant intercepts). Of note, all geophysical anomalies drilled
have proven to be directly related to the presence of sulphides.

The Phase 1 drill program has been completed early to allow for a two-week period of
detailed evaluation of results and completion of a campaign of geological and
geophysical investigations. This program will apply the information gained from work to
date to target possible extensions to mineralisation intersected in DMRC003 plus refine
targeting for drill testing during Phase 2.
Immediate proposed work at Double Magic
An intensive technical program of results assessment, field mapping, on-ground
geological interpretation, structural analysis, and several types of geophysical surveys
(including down-hole EM surveys and possibly high powered ground EM surveys) will
commence immediately. This work is the next step in Buxton’s ongoing exploration of
the Double Magic project, summarised as follows;
o Reconnaissance Phase 1 RC drilling - now complete
o Local and prospect-scale multi-disciplinary technical Investigations completed by end August; and
o Local and prospect-scale follow-up Phase 2 RC and/or diamond drilling –
to commence within weeks.
Locations and sketch geology are indicated in the attached map (Figure 1). DMRC003

OTHER PROJECTS
Zanthus Summary
The Company’s 100% owned, highly prospective Zanthus Ni-Cu Project is located 60km
along strike from Sirius Resources’ Nova-Bollinger Ni-Cu discovery in the Fraser Range
Nickel province, Western Australia.
The Company’s recent drilling program targeted two conductors, ZM02 and ZM07
(Figure 4). Drill hole ZRC095 on conductor ZM02 was completed at 306m with a zone
of disseminated pyrrhotite and minor chalcopyrite in gneiss over 20m explaining the
conductor. Recently received assay data confirms the interpreted sulphide
mineralization in ZRC095 with no significant Ni-Cu mineralisation.
Drill hole ZRC096 targeting the large ZM07 conductor at ~700m depth has been
temporarily suspended at 256m due to technical difficulties associated with running
sands. ZRC096 will be continued at a later date.

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 (eg ‘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 (eg
submarine nodules) may warrant disclosure of detailed
information.
Drill type (eg core, reverse circulation, open-hole
hammer, rotary air blast, auger, Bangka, sonic, etc) and
details (eg 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).
Exploration drilling at the Double Magic and Zanthus
Projects has been undertaken utilizing a Reverse
Circulation (RC) rig. The same drill contractor and
processes have been employed at both Projects.
Drilling techniques
Drill sample recovery
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.
The drillhole locations are picked up by handheld GPS.
Sampling was carried out under Buxton protocols and
QAQC procedures are per industry best practice.
RC drilling was employed to generate 1m samples. A rig
mounted cyclone and cone splitter was used to provide a
bulk sample and a representative split sample for assay.
Either the 1m split or a composite (hand speared)
sample was collected for assay purposes.
Samples are submitted to Intertek Genalysis in Perth for
analysis. A standard dry, crush and pulverize was
followed by a 25g charge for fire assay with an ICP-MS
finish for Au, Pt, Pd and a four-acid digestion finished
with ICP-OES for a suite of 33 elements.
WBH Drilling completed a total of 9 holes for 1,333m of
RC drilling at the Double Magic Project, completing the
Phase 1 drill program.
WBH Drilling completed a total of 2 holes for 562m of RC
drilling at the Zanthus Project. The drill program was
temporarily suspending due to technical difficulties
associated with running sands.
The RC bulk sample recovery is routinely examined for
representivity. It is not believed that any bias has
occurred due to loss or gain of sample.
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.
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.
100% of the drill holes are geologically logged in real
time by qualified and experienced geologists, recording
relevant data to a set template. All logging included
lithological features, mineral assemblages and estimated
mineralization percentages. All data was codified to a set
of company code systems. All chips are photographed.
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.
All 1m intervals were split with a rig mounted cone
splitter. Non-mineralised analysis samples were
prepared as multiple metre (generally 4m composites)
spear samples. Sample preparation is consistent with
industry best practice. Field QC procedures involved the
use of certified reference material assay standards,
blanks and duplicates for company QC measures, and
laboratory standards, replicate assaying and barren
washes for laboratory QC measures. The insertion rate of
each of these QAQC measures averaged 1:20. The
sample size is deemed appropriate for the material and
analysis method.
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.
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.
The samples were analysed at Intertek Genalysis in
Perth, Australia. Sample preparation included drying,
crushing, splitting and pulverizing. A four acid digest
followed by a 33 element ICP analysis was conducted on
all samples. The samples were also analysed by Fire
Assay with an ICP finish for Au, Pt and Pd. The laboratory
procedures are considered to be appropriate for
reporting according to industry best practice.
Verification of
sampling and
assaying
Location of data
points
Data spacing and
distribution
Orientation of data in
relation to geological
structure
Sample security
Audits or reviews
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 verification of significant intersections by either
independent or alternative company personnel.
Significant mineralization has been verified by
alternative company personnel.
The use of twinned holes.
There have been no twinned holes due to the early stage
nature of this exploration program.
Documentation of primary data, data entry procedures,
data verification, data storage (physical and electronic)
protocols.
All data is collected initially on paper and handheld GPS.
This data is hand entered to spread sheets and validated
by Company geologists. This data is then imported and
validated using MapInfo software. Physical data sheets
are stored at the company office. Digital data is securely
archived on and off-site.
No adjustments to assay data have been made.
Handheld GPS (+/-5m) as well as reference to
topographical and remote sensing data.
Discuss any adjustment to assay data.
Accuracy and quality of surveys used to locate drill holes
(collar and down-hole surveys), trenches, mine workings
and other locations used in Mineral Resource estimation.
Specification of the grid system used.
Quality and adequacy of topographic control.
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to
establish the degree of geological and grade continuity
appropriate for the Mineral Resource and Ore Reserve
estimation procedure(s) and classifications applied.
Whether sample compositing has been applied.
Whether the orientation of sampling achieves unbiased
sampling of possible structures and the extent to which
this is known, considering the deposit type.
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.
The results of the laboratory-inserted standards, blanks
and sample repeats demonstrate the accuracy and
precision of methods employed.
MGA51 (GDA94).
Topographic elevation was recorded via handheld GPS
and checked against remote sensing data, this is deemed
sufficient for this stage of exploration.
Drill holes are based on geophysical targets and not
equally spaced. Samples from DMRC003 were taken as
1m splits for the entire hole.
Not applicable – No Mineral Resource or Ore Reserve
calculations have been performed.
Due to the early stage of investigation and the nature of
drilling (RC chips) it is not possible to determine the
amount of bias due to the relationship between drilling
orientation and orientation of mineralization.
All mineralized intervals are down hole intervals, not
true width.
Samples were packaged and stored in secure storage
from the time of gathering through to submission.
Laboratory best practice methods were employed by the
laboratory upon receipt. Returned pulps will be stored at
a secure company warehouse.
No audits of the sampling techniques or data were
carried out due to the early stage of exploration. It is
considered by the Company that industry best practice
methods have been employed at all stages of the
exploration.

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:
The Zanthus Project is located in the Fraser Range
region of Western Australia and consists of one
exploration licence (E28/1959) held by Buxton
Resources Limited.
The tenements are in good standing with the DMP and
there are no known impediments for exploration on
these tenements.
Data used during the appraisal of the Double Magic
Project (previously known as the Alexander Creek
Project, Clara Hills, Jack’s Hill, Limestone Springs &
Maura’s Reward) has been collected by numerous
exploration parties, including Alexander Creek Pty Ltd,
Victory Mines Limited (ASX:VIC), Proto Resources and
Investments Limited (ASX:PRW), and Ram Resources
Limited (ASX:RMR). All geophysical data has been
independently reviewed by Southern Geoscience
Consultants. All historical data presented has been
previously reported under JORC 2004 and there has
been no material change (see Competent Persons
Statement for details of original reports).
The Double Magic Project area lies within the
Palaeoproterozoic Hooper Province of the King Leopold
Orogen in the Kimberley region of Western Australia.
The geology of the Project is characterized by mica
schists of the Marboo Formation which are intruded by
thick sills of the Ruins Dolerite. The Ruins Dolerite is a
medium- to fine-grained mafic-ultramafic intrusive that
is host to the known nickel-copper sulphide
mineralization. This mineralization is interpreted to
represent primary orthomagmatic sulphide
mineralization, however there appears to be significant
re-working and alteration of the mineralization in places
(in particular at the Jack’s Hill Gossan where the
mineralization is dominated by copper carbonates and
contains limited nickel). Importantly the gossan at Jack’s
Hill does not have an electromagnetic (EM) signature,
whereas the EM targets tested to date all appear to be
due to nickel and copper enriched sulphide
mineralization.
The Zanthus Project area lies within the Fraser Zone of
the Albany-Fraser Orogen. The Fraser Zone is
dominated by Mesoproterozoic high-grade
metamorphic rocks that have a strong, distinct
geophysical signature in both aeromagnetic and gravity
data – the latter reflecting the high density attributed to
the dominance of metagabbroic rocks. The
mineralization model at Zanthus is primary magmatic
nickel-copper sulphide.

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
(eg cutting of high grades) and cut-off grades are usually
Material and should be stated.
No weighting, truncations, aggregates or metal
equivalents were used.
Relationship between
mineralisation widths
and intercept lengths
Diagrams
Balanced reporting
Other substantive
exploration data
Further work
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.
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’).
The relationship between the true mineralization width
and intercept length is not known at this early stage of
drilling, however true width of the intercept in
DMRC003 is interpreted to be less than intercept
length.
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.
Refer to figures/tables in body of release.
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 (eg tests for
lateral extensions or depth extensions or large-scale stepout drilling).
There is no other exploration data that is deemed to be
meaningful or material.
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 modelled conductors in Figures within the text of
this report. Additional zones of interest may be
established based on geological information (such as
drilling or downhole data). Regionally, the extensive
land package containing significant exposure of the
nickeliferous host lithology the Ruin’s Dolerite are of
exploration interest.
All currently available exploration results have been
reported.
