High-grade copper assay results from RC drilling in Upper Zone
Talisman Mining Limited (ASX: TLM “Talisman”) is pleased to announce that
Sandfire Resources NL (ASX: SFR; “Sandfire”) has provided an update on
ongoing activities at the Monty copper-gold discovery within Talisman’s
Springfield Project located approximately 10km east of the DeGrussa CopperGold Mine (see Appendix 1).
Monty is the first significant VMS copper-gold discovery in the Doolgunna region
outside of DeGrussa and Sandfire is continuing drilling to define the extents of
mineralisation at Monty itself and to target other prospective areas; both in the
immediate vicinity and further afield.
The collar locations of holes drilled to date by Sandfire are shown in the plan view
diagram below (see Figure 1) and Table 1.

Monty Update
Massive sulphides intersected up-dip in Lower Zone
Diamond drill hole TLDD0021 was drilled approximately 64 metres up-dip of TLDD0009 (7.9m @ 8.3% Cu
and 2.4 g/t Au from 363.1m down hole and 4.8m @ 4.9% Cu and 1.1 g/t Au from 385.8m down hole) (see
TLM ASX announcement - 8 September 2015) and approximately 104 metres down-dip of TLDD0016, which
did not intersect massive sulphides (see TLM ASX announcement - 14 September 2015).
Sandfire have advised that TLDD0021 intersected four zones of massive sulphides within the host
sequence of the Lower Zone:
0.6 metres of massive sulphides from 239.8m to 240.4m down-hole
(true width not known at this time, top of intercept is approximately 211m vertically below surface);
1.4 metres of massive sulphides from 241.0m to 242.4m down-hole
(true width not known at this time, top of intercept is approximately 212m vertically below surface);
7.3 metres of massive sulphides from 286.2m to 293.5m down-hole
(true width not known at this time, top of intercept is approximately 250m vertically below surface); and
1.2 metres of massive sulphides from 299.8m to 301.0m down-hole
(true width not known at this time, top of intercept is approximately 263m vertically below surface).
Assay Results - TLRC0008
Sandfire have also advised that it has received assay results from the relatively shallow Reverse Circulation
(RC) drill hole TLRC0008 (refer Figure 1 and Table 1) located south west 40 metres along strike from the initial
Upper Zone discovery hole TLRC0004 (18m grading 5.7% Cu and 2.4g/t Au from 107.0m) (see TLM ASX
announcement - 13 August 2015). These assay results are:
6.0 metres grading 7.8% Cu and 0.9g/t Au from 89m to 95m down-hole
(true width not known at this time but likely to be considerably thinner than down-hole width, top of
intercept is approximately 90m vertically below surface); and
11.0 metres grading 15.0% Cu and 1.9g/t Au from 112m to 123m down-hole
(true width not known at this time but likely to be considerably thinner than down-hole width, top of
intercept is approximately 100m vertically below surface).
Sandfire have advised that the upper intersection of TLRC0008 (6.0 metres at 7.8% Cu and 0.9g/t Au) visually
exhibited weak oxidation of the massive sulphides. Sandfire have also advised that they therefore believe that it
is possible that the grades in this upper intersection may have been elevated by supergene processes.
Monty Update
Geological Discussion / Interpretation
Ongoing work at Monty has provided sufficient detail to enable Sandfire to provide an updated
interpretation of the geological setting of the known mineralisation at Monty. An updated vertical
longitudinal projection (looking to the south-east) is shown in Figure 2 below. Specific interpretation of the
upper and lower mineralised zones at Monty is discussed below.
Figure 2 – Vertical longitudinal projection of Monty showing drill-hole piercepoints at the top of the primary intercept
shown in bold. All intercepts are down-hole widths.
Initial interpretation of the Lower Zone
The Lower Zone at Monty incorporates the massive sulphide mineralisation intersected in TLDD0004A,
TLDD0005, TLDD0009, TLDD0010 (previously reported) and TLDD0021 (reported above, assays pending).
The mineralisation seen in the drilling so far, can be interpreted as a dominant primary lens (as seen in holes
TLDD0004A and TLDD0005), with possibly stacked subordinate lenses, above and below the primary lens, in
certain areas (as seen in holes TLDD009, TLDD0010 and TLDD0021). This is illustrated in the interpretive
cross-section for the Lower Zone as shown in Figure 3 on the following page.
Other minor intersections of massive sulphides in surrounding holes, and the top of alteration and disseminated
sulphides in the periphery of the mineralisation, have informed this interpretation by Sandfire. The primary zone
of mineralisation strikes approximately 220° and ranges in dip from 65°- 85° to the north-west.
Monty Update
Figure 3 – Interpretive cross-section of the Monty mineralisation (Lower Zone)
Initial interpretation of the Upper Zone
The mineralisation in the Upper Zone, and its host stratigraphy, is currently defined by RC holes TLRC0004,
TLRC0008 and TLRC0009 (as previously reported, see Figure 1 and Figure 2 on preceding pages). Sandfire
interpret the geometry of the Upper Zone to be steep to sub-vertical in dip.
As a result, Sandfire interpret that the RC holes in the Upper Zone are likely to have intersected the
mineralisation at a low angle, with the reported down-hole intersections potentially being considerably thicker
than the anticipated true width. The grades reported in this Upper Zone may also therefore not be fully
representative and further drilling is required to confirm the interpretation and determine the optimum angle for
drilling to further define the mineralisation.
All current drill holes in the Upper Zone at Monty are drilled towards the south-east. In order to confirm and
refine the above geological interpretation additional holes are planned by Sandfire to be drilled towards the
north-west. Sandfire advise that these holes will be drilled both up-dip and down-dip of the existing intercepts in
holes TLRC0004, TLRC0008, and TLRC0009.
Monty Update
Other Exploration
Sandfire have also advised Talisman of the results from two other drill holes; TLRC0012 and TLDD0022.
TLRC0012 was drilled to the south-east (approximately 110 metres up-dip) of TLRC0009, after penetrating the
transported cover, intersected a 13 metre interval of sediment before entering dolerite. This sediment is
interpreted by Sandfire to be the lower part of the host horizon (below the level of mineralisation in the Upper
Zone) and is considered to be consistent with the geological interpretation that the mineralisation in the Upper
Zone, and its host stratigraphy, has a steep to sub-vertical dip.
TLDD0022 was drilled approximately 130 metres down-dip of TLRC0008 and was designed to define the margin
of the mineralisation in this area. The hole intersected the host horizon sediments, with weak chloritic alteration,
without intersecting any massive sulphide mineralisation.
Further Exploration Activity
Sandfire are continuing drilling at Monty with further diamond holes underway and planned to test the
interpreted extents of the mineralisation in the Lower Zone, as well as to confirm the dip of the mineralisation in
the Upper Zone.
In addition to continuing definition drilling around the currently known mineralisation, Sandfire are also working
towards generating potential exploration targets along the highly prospective 5km Monty corridor as part of the
search for additional lenses of mineralisation at Monty.
Further afield within the Springfield Project, Sandfire consider the Homer Prospect to be a high priority
exploration target area which lies within the immediate eastern extension of the DeGrussa Mine Corridor.
Additional drilling at Homer is planned by Sandfire
The Springfield Project is subject to an exploration farm-in joint venture between Sandfire and Talisman where
Sandfire has the right to earn up to a 70% interest in Talisman’s Doolgunna Projects by the expenditure of $15
million on exploration at the Projects.

Commentary
Sampling
techniques
Nature and quality of sampling (e.g.
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).
Sandfire diamond drilling is completed using
NQ2 size coring equipment.
RC drilling is with a face sampling hammer of a
nominal 140mm hole diameter.
All drill collars are surveyed using RTK GPS.
All core, where possible is oriented using a
Reflex ACT II RD orientation tool.
Downhole surveying is undertaken using a
gyroscopic survey instrument.
Drilling
techniques
The sampling method employed by Sandfire i s
h a l f -core sampling of NQ2 core from
diamond drilling (DD)
Sandfire collect RC samples by cone splitter for
single metre samples or a sampling spear for first
pass composite samples using a face sampling
hammer with a nominal hole diameter of 140mm
Sampling is guided by Sandfire protocols as per
industry standard.
Diamond drill core sample size reduction is
through a Jaques jaw crusher to -10mm and a
second stage reduction via Boyd crusher to 4mm.Representitive sub samples are split and
pulverised via an LM5 mill.
RC samples are crushed to -4mm through a
Boyd crusher and representative sub samples
are split and pulverised with an LM5 mill.
Pulverising is to nominal 90% passing -75µm and
is checked using wet sieving technique.
Samples are assayed using Mixed 4 Acid
Digest (MAD) 0.3g charge and MAD Hotbox
0.15g charge methods with ICPOES or ICPMS.
Fire Assay is completed by firing 40g portion of
the sample with ICPMS finish.

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.
Sandfire diamond core recovery is logged and
captured into the database. Core recoveries are
measured by drillers for every drill run. The core
length recovered is physically measured for each
run and recorded and used to calculate the core
recovery as a percentage of core recovered.
Appropriate measures are taken to maximise
sample recovery and ensure the representative
nature of the samples. This includes diamond core
being reconstructed into continuous intervals on
angle iron racks for orientation, metre marking and
reconciled against core block markers.
RC sample recovery is good with almost no wet
sampling in the project area
Samples are routinely weighed and the information
captured into the central secured database.
No sample recovery issues have impacted on
potential sample bias
Sandfire Geological logging is completed for all
holes and is representative across the orebody.
The lithology, alteration and structural
characteristics of core are logged directly to a
digital format following procedures, and using
Sandfire NL geologic codes. Data is imported into
Sandfire NL’s central database after validation in
LogChief™.
Logging is both qualitative and quantitative
depending on field being logged.
All cores are photographed.
All drill holes are fully logged.
Sandfire complete diamond core orientation
where possible and all core is marked prior to
sampling. Half core samples are produced using
an Almonte Core Saw. Samples are weighed and
recorded.
RC samples are split using a cone or riffle splitter.
The majority of samples collected are dry. On
occasion that wet samples are encountered they
are dried prior to splitting with a riffle splitter.
All samples are sorted, dried at 80° for up to 24
hours and weighed. Samples are then crushed
through a Jaques crusher to nominal -10mm. A
second stage crushing is through a Boyd crusher
to nominal -4mm.
Sample splits are weighed at a frequency of 1:20
and entered into the job results file. Pulverising is
completed using LM5 mill to 90% passing 75%µm
using wet sieving technique.
1:20 grind quality checks are completed for 90%

No field duplicates have been taken.
The sample sizes are considered appropriate for
VHMS and Gold mineralisation types.
Samples are assayed using Mixed 4 Acid Digest
(MAD) 0.3g charge and MAD Hotbox 0.15g
charge methods with ICPOES or ICPMS. The
samples are digested and refluxed with a mixture
of acids including Hydrofluoric, Nitric,
Hydrochloric and Perchloric acids and analysis
conducted for multi elements including Cu, Pb,
Zn, Ag, As, Fe, S, Sb, Bi, Mo, Re, Mn, Co, Cd,
Cr, Ni, Se, Te, Ti, Zr, V, Sn, W and Ba. The MAD
Hotbox method is an extended digest method
that approaches a total digest for many elements
however some refractory minerals are not
completely attacked. The elements S, Cu, Zn,
Co, Fe, Ca, Mg, Mn, Ni, Cr, Ti, K, Na, V are
determined by ICPOES, and Ag, Pb, As, Sb, Bi,
Cd, Se, Te, Mo, Re, Zr, Ba, Sn, W are
determined by ICPMS. Samples are analysed for
Au, Pd and Pt by firing a 40g of sample with ICP
AES/MS finish. Lower sample weights are
employed where samples have very high S
contents. This is a classical FA process and
results in total separation of Au, Pt and Pd in the
samples.
The analytical methods are considered
appropriate for this mineralisation styles.
No geophysical tools are used in the analysis.
Sandfire DeGrussa QAQC protocol is considered
industry standard with standard reference
material (SRM) submitted on regular basis with
routine samples. SRMs and blanks are inserted
at a minimum of 5% frequency rate.
Significant intersections have been verified by
alternate Sandfire personnel.
None of the drillholes in this report are twinned.
Primary data is captured on field Toughbook
laptops using Logchief™ Software. The software
has validation routines and data is then imported
into a secure central database.
The primary data is always kept and is never
replaced by adjusted or interpreted data.

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.
Sample
security
The measures taken to ensure sample
security.
Sandfire ensures appropriate security measures
are taken to dispatch samples to the laboratory.
Chain of custody of samples is being managed
by Sandfire Resources NL. Samples are stored
onsite and transported to laboratory by a licence
transport company in sealed bulka bags. The
laboratory receipts received samples against the
sample dispatch documents and issues a
reconciliation report for every sample batch.
Audits or
reviews
The results of any audits or reviews of
sampling techniques and data.
Sandfire have not completed any external audits
or reviews of the sampling techniques and data
Data
spacing
and
distribution
Drill spacing is currently defined by geological
criteria and is regarded as appropriate to
determine the extents of mineralisation. This
spacing is nominally 80m x 80m. Spacing is
shown by the accompanying tables and figures.
Exploration drilling at Monty is preliminary and
spacing and distribution of exploration results is
not sufficient to support Mineral Resources or
Ore Reserves.
No sample compositing has been applied to
these exploration results.
No significant orientation based sampling bias is
known at this time.
The drill holes may not necessarily be
perpendicular to the orientation of the intersected
mineralisation. All reported intervals are
downhole intervals, not true widths. This will be
established with additional drilling.

Diamond and RC drilling by Farm-in Partner
Sandfire is on tenements E52/2313 and
E52/2282. Tenements E52/2282, E52/2313 and
E52/2466 form Talisman’s 100% owned
Springfield Project, 150km north-east of
Meekatharra, WA. Sandfire is currently farming
into the project on a staged basis with the right to
earn 70% interest in the project

Geology
Deposit type, geological setting and
style of mineralisation.
All tenements are current and in good standing.
The Talisman tenements are currently subject to a
Native Title Claim by the Yungunga-Nya People
(WAD6132/98). Sandfire currently has a Land
Access Agreement in place with the YungungaNya Native Title Claimants and have assumed
management of Heritage Agreements which were
executed by Talisman. These agreements allow
Sandfire to carry out mining and exploration
activities on their traditional land.
Aside from Sandfire Resources and Talisman
Mining Limited there has been no recent
exploration undertaken on the Talisman Project.
Historic exploration work at Springfield completed
prior to Talisman’s tenure included geochemical
soil and rock chip sampling combined with
geological mapping. Some targeted RC drilling
was completed over gold and diamond targets.
Talisman’s Doolgunna Project lies within the
Proterozoic-aged Bryah rift basin enclosed
between the Archaean Marymia Inlier to the north
and the Proterozoic Yerrida basin to the south.
The principal exploration targets at the Doolgunna
Projects are Volcanogenic Massive Sulphide
(VMS) deposits located with the Proterozoic Bryah
Basin of Western Australia.

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
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
o hole length.
Refer to Table 1 of this document – Drillhole
Information Summary, Springfield Project.
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.
Data
aggregation
methods
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.
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.
Significant intersections are based on greater
than 0.5% Cu and may include up to a
maximum of 3.0m of internal dilution, with a
minimum composite grade of 1.0% Cu.
Cu grades used for calculating significant
intersections are uncut.
Minimum and maximum diamond core sample
intervals used for intersection calculation are
0.3m and 1.2m respectively subject to location
of geological boundaries.
Reported intersections from RC drilling are based
on regular 1 metre sample intervals.
No metal equivalents are used in the intersection
calculation.
Where core loss occurs; the average lengthweighted grade of the two adjacent samples
are attributed to the interval for the purpose of
calculating the intersection. The maximum
interval of missing core which can be
incorporated with the reported intersection is
1m.
