Highlights
Double Magic Ni & Cu – West Kimberley
Buxton acquired 100% Double Magic which is located in the Kimberley in a mirror
tectonic position & within similar age mafic-ultramafic rocks as the Savannah Mine of
Panoramic Resources Ltd (ASX: PAN) (3.1Mt @ 1.5% Ni, 0.9% Cu & 0.08% Co)
Numerous strong EM conductors within a 2km2 central area including conductor D with a
conductance of ~15,000 siemens (Nova ~5,100 siemens)
Previously drilled EM conductors shown to be due to nickeliferous sulphides (not
graphite or barren iron sulphides)
Historic drill results include 3m @ 1.3% Ni & 0.2% Cu with 1m @ 2.0% Ni & 0.2% Cu at
conductor C
High-grade Ni-Cu gossans located up dip of conductor A and primary Ni-Cu sulphides
discovered in rock-chips up-dip of conductors D & C
~2,500m RC drilling program is planned to begin late July to test nine conductors,
including three high priority targets for Ni-Cu sulphide mineralisation
Zanthus Ni & Cu – Fraser Range
Buxton commenced a two hole, ~1,100m RC drilling program at its Zanthus Ni-Cu
sulphide project to test two high priority conductors for Ni-Cu sulphide mineralisation
Hole ZRC095 on conductor ZM02 was completed at 306m with a zone of disseminated
pyrrhotite & minor chalcopyrite in gneiss over 20m explaining the conductor. Samples
have been dispatched to the laboratory and assays will be reported when available
Hole ZRC096 targeting the large ZM07 conductor at ~700m depth temporarily suspended
at 256m due to difficulties associated with running sands in top 40m of the hole. ZRC096
to be continued at a later date once appropriate steel casing is manufactured
The drilling contractor has also undertaken to re-mobilise to Zanthus and re-enter
ZRC096 at no cost to Buxton

Double Magic Ni & Cu – West Kimberley
Figure 1. Location of the Double Magic Ni-Cu Project in the Kimberley region of Western Australia. Also
shown is the location of Panoramic’s Savannah Ni-Cu Mine.
During the quarter, Buxton acquired a 100% interest in the Double Magic Nickel Project in the Kimberley
region of Western Australia (Figure 1). The project contains at least three existing, “walk-up” drill targets
that were either untested or only partially tested by previous drilling. Additionally, re-interpretation of
geological and geophysical datasets by Buxton’s consultants and experienced geological team has
shown that all conductors occur within the known nickel host rock, the Ruins Dolerite, and therefore
have a strong chance of being due to nickel sulphides (not graphite or barren iron sulphides).
Buxton has acquired a 100% interest in the four highly prospective tenements (the Double Magic Nickel
Project totaling ~93km2) in return for issuing the vendors 1,666,666 fully paid Buxton shares. In addition,
Buxton will issue the vendors up to three tranches of milestone shares when specific technical hurdles
are met (total cumulative value of all three tranches is approximately $120,000).
Regional Geology
The Double Magic Project lies within the King Leopold Orogen which is comprised of Palaeoproterozoic
schists and igneous rocks of the Hooper Complex and the deformed margins of the Speewah and
Kimberley Basins (Figure 1). Within the Hooper Complex, schists of the Marboo Formation are intruded
by thick sills of Ruins Dolerite (Figure 2).
Sills of the Ruins Dolerite host the known nickel-copper sulphide mineralisation. The sills are indistinctly
layered, contain pods of meta-peridotite and are up to several hundred metres thick. The Ruins Dolerite
is very similar in age and composition to intrusions in the Halls Creek Orogen such as the Sally Malay
Suite that hosts the Savannah Nickel-Copper Mine of Panoramic Resources.
Project Geology & Previous Exploration
The project area is characterized by mica schists of the Marboo Formation which are intruded by sills of
Ruins Dolerite. Granitoids of the Paperbark Supersuite occur in the north-east of the project area (Figure
2).
At Jack’s Hill, a copper-nickel gossan occurs near the contact of the Ruins Dolerite and the mica schists
of the Marboo Formation. To the west and north-west of the gossans several large hills comprised of
Ruins Dolerite occur.
Initial exploration at the project focused on the Jack’s Hill gossan. In 2007, two RC drill programs and
one ground EM survey highlighted wide spread low-grade (typically ~0.2-0.4% Ni) sulphide
mineralisation in the vicinity of the gossan.
In 2013 a helicopter VTEM survey identified eight significant conductors (Figure 2), with five located
within a ~1.5km radius and interpreted to be associated with the margins of multiple Ruins Dolerite sills.
These five VTEM conductors were further followed up with ground EM which resulted in the definition of
seven discrete bedrock conductors.
A four hole drill program was undertaken to test these ground EM conductors. Two of the holes
(CHRC012 & CHRC013) intersected highly encouraging, significant Ni-Cu sulphide mineralisation.
Importantly, both the most conductive target and separately the largest conductor, were not drill tested
in the program.

Observations from Mapping and Rock-chip Sampling
Buxton’s geologists have conducted further detailed geological mapping and rock-chip sampling around
the central zone of targets at Double Magic. Major observations and results include;
Identification of a discrete, coarse grained gabbro unit interpreted to be located stratigraphically
below a high-Mg dolerite unit (Ruins Dolerite)
A rock-chip sample located up-dip from the modelled plate at Conductor D returned modal
percentages of nickel, copper and iron sulphides indicative of a primary magmatic source.
Conductor D is located just above a distinctive gabbro unit and thus is tentatively interpreted to
be located toward the base of the high-Mg dolerite unit – an ideal location for an accumulation
of sulphides (Figure 3)
At Conductor A, a 200m+ long zone of high-grade nickel-copper gossan outcrop has now been
defined
At Conductor C, a number of highly anomalous nickel-copper assays were returned from rockchip samples
Geochemical analysis of all anomalous nickel-copper rock-chip samples show that they are
from a primary sulphide source and predominantly not related to surface enrichment (Figure 4)
Figure 3. Conductor D, TEM response, modelled conductor and planned drill-holes.
Figure 4. Double Magic mineralised rock-chip samples plotted on Bull & Mazzuchelli primary nickel
sulphide discriminator.
The Company plans to drill test nine separate targets at the Double Magic project beginning in late July
2015. Three of the conductors are deemed high priority with each of these occurring within the known
nickel host rock, the Ruins Dolerite;
•
Conductor D: Untested with drilling. The ground EM response is an order of magnitude greater
than the other conductors with a conductance of ~10,000-15,000S (Nova 5,100S). Magmatic NiCu sulphides have been discovered in outcrop in a location directly up-dip from the modelled
conductor plate. This strongly upgrades the target by suggesting the source of the conductor is
nickeliferous sulphides (not graphite or barren iron sulphides). The modelled conductor has an
extent of circa 100m x 30m (Figures 3 & 5).
•
Conductor C: Previously partially drill tested with one hole that intersected nickel-copper
sulphide mineralization (3m @ 1.3% Ni & 0.2% Cu and 6m @ 0.5% Ni & 0.2% Cu). No
additional drilling or downhole EM was conducted on this target. The highest ground EM
response (to the east) was not drill tested. Rock-chip samples with highly anomalous nickel and
copper assays plus visual sulphides were taken near the up-dip extent of the conductor. The
conductance is ~1,500S (Figure 5)
•
Conductor B: Untested with drilling. The modelled conductor has the largest spatial extent of
any of the targets. It is likely related to conductor A, where previous drilling intersected nickelcopper sulphide mineralisation (3m @ 0.7% Ni and 0.2% Cu) and rock-chip samples of up to
6.0% Ni + 1.1% Cu have been taken. The modelled conductor has an extent of circa 300m x
100m. The conductance is ~1,000S to ~2,000S (Figure 5)
Critically, all conductors effectively tested to date by historical drilling have been verified as being due to
nickeliferous sulphide mineralisation. Importantly, no graphite, barren sulphides or any other conductive
material was encountered. This significantly upgrades the potential of the target conductors to represent
Ni-Cu sulphide mineralisation.
Drilling is due to start on or around 31st July 2015.

Zanthus – Fraser Range (100% BUX)
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 drilling program targeted two conductors, ZM02 and ZM07. 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. Samples have been dispatched to the laboratory and assays will be
reported when available.
Zanthus hole ZRC096 targeting the large ZM07 conductor at ~700m depth has been temporarily
suspended at 256m due to technical difficulties associated with running sands in the top 40m of the
hole. ZRC096 is to be continued at a later date once appropriate steel casing is manufactured to case
the top 40m of the hole. Additionally, the drilling contractor has undertaken to re-mobilise to Zanthus and
re-enter ZRC096 at no cost to Buxton.
Yalbra Graphite – Gascoyne Region
Buxton reported initial flotation and acid purification test-work results for its high-grade Yalbra Graphite
Project in Western Australia.
Flotation batch test results from a representative fresh rock diamond drill sample grading 20.0% C(t)
returned a concentrate grade of 91% C(t). This concentrate showed a good proportion of medium to
coarse flake material with 30% falling into categories above +149 microns in size (Table 1). The overall
recovery of graphite was 80%, although this should be improved in future locked cycle tests. The
process involved a primary grind, a rougher flotation stage, 2 stages of polishing grind and 5 cleaner
flotation stages.
A final leaching stage using a combined H2SO4/HF solution to upgrade the concentrate was also
completed and showed that a final concentrate grading 99.5% C(t) could be achieved, with the coarser
size fractions grading as high as 99.7% C(t).
Yalbra is Australia’s highest reported grade graphite resource at 4.0Mt @ 16.2% TGC (Inferred) and has
considerable potential to be expanded along strike, and for discovery of additional resources.
Additionally, Buxton has shown commercial products can be produced from its very high grade Yalbra
Graphite Project. As such, the Company is now in a position to seek a development and/or offtake
partner to assist in commercialising the project.
