Talisman Mining Limited (ASX: TLM “Talisman”) is pleased to announce that
Sandfire Resources NL (ASX: SFR; “Sandfire”) has advised that diamond
drilling undertaken by Sandfire as part of an exploration farm-in joint venture at
Talisman’s Springfield Project, has intersected a zone of massive sulphides at
the Monty Prospect, approximately 10km east of Sandfire’s DeGrussa Copper
Mine.
Diamond drill hole TLDD004A intersected 14 metres of massive sulphides
from 411m down-hole to 425m (for hole details see Table 1). Based on field
observations by Sandfire, the interval contains visible chalcopyrite and is
similar to the massive sulphides seen at DeGrussa.

Drilling is continuing with the hole currently in fragmental siltstone and basalt
with trace chalcopyrite and pyrrhotite to 427m down-hole. Note, all widths are
down hole as true widths are not currently known.
TLDD004A was drilled as a follow-up hole to TLDD002A, completed by
Sandfire last month, which intersected a sedimentary package that closely
resembles the exhalative VMS sequence observed in proximity to the massive
sulphide mineralisation at the Conductor 5 deposit.
TLDD004A was designed to intersect an off-hole EM response identified from
DHEM surveys undertaken by Sandfire on the original Talisman drill-hole
SPD021 and refined by Sandfire in subsequent DHEM surveys.
Sandfire have advised that diamond drill core from TLDD004A will be
dispatched for priority assaying, with results expected in the coming weeks.
Talisman and Sandfire are very encouraged by the intercepted massive
sulphide in TLDD004A, which represents the first significant accumulation of
massive sulphides to be intersected within either Talisman’s or Sandfire’s
Doolgunna projects outside of the four known lenses of VMS mineralisation at
DeGrussa.
Sandfire have advised that follow-up diamond drilling will be undertaken as a
priority.
Sandfire has the right to earn up to a 70% interest in Talisman Mining’s
Doolgunna Projects by the expenditure of $15 million on exploration at the
Projects.

Appendix 1 - JORC TABLE 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
Criteria
JORC Code explanation
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.
Sampling is intended. Not applicable to this release.
Drilling
techniques
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, facesampling bit or other type, whether core
is oriented and if so, by what method,
etc).
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.
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.
Sandfire diamond drilling is completed by DD rig using NQ2
coring equipment.
All drill collars are surveyed using an RTK GPS survey
instrument.
All core is oriented, where possible, using an electronic core
orientation tool (Reflex ACT).
Downhole surveying is undertaken using a gyroscopic
survey instrument.
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, recorded and used to calculate the
core recovery as a percentage core recovered.
Sandfire ensure 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
and reconciled against core block markers.
No sample recovery issues have impacted on reported width
of mineralisation.
Springfield Project Exploration Update
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.
Sandfire completes geological logging for all holes that i s
representative across the ore body. The lithology, alteration,
and structural characteristics of core are logged and
captured in digital format using Sandfire Resources NL
geology codes and following established procedures. Data
is imported into Sandfire Resources NL’s central database
after validation in LogChief™.
Logging is both qualitative and quantitative depending on the
attribute being logged.
Sandfire photograph all drill core.
All drill holes are fully logged by Sandfire.
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 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.
Sampling is intended. Not applicable to this release.
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 (e.g. standards, blanks,
duplicates, external laboratory checks)
and whether acceptable levels of
accuracy (i.e. lack of bias) and precision
have been established.
Analyses are intended. Not applicable to this release.
Sandfire have not used any geophysical tools or hand held
analytical instruments in the preparation of this release.
Verification of
sampling and
assaying
The verification of significant
intersections by either independent or
alternative company personnel.
The use of twinned holes.
Documentation of primary data, data
entry procedures, data verification, data
storage (physical and electronic)
protocols.
Discuss any adjustment to assay data.
Determination of reported down hole intervals of visible
mineralisation have been verified by alternate Sandfire
personnel
None of the drill holes in this report are twinned.
Primary data is captured by Sandfire personnel on field tough
book 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.
Springfield Project Exploration Update
Location of
data points
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.
Sandfire Survey team undertakes survey works under the
guidelines of best industry practice.
All drill collars are accurately surveyed using RTK GPS system
within +/-50mm of accuracy (X, Y, Z).
Coordinates are based on control previously established by
MHR Surveyors which was derived by ties into the
Government SSM/BM network.
Downhole survey completed by gyroscopic survey at regular
intervals
Coordinate and azimuth are reported in MGA 94 Zone 50.
Topographic control was established from aerial photography
using a series of 33 surveyed control points.
Data spacing
and distribution
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.
As TLDD0004a is the first drill hole to intersect the modelled
EM plate, it is not possible to make any conclusions regarding
sample spacing and distribution.
Orientation of
data in relation
to geological
structure
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.
Drill hole TLDD0004a was orientated to intersect a modelled
EM plate. The drill hole may not necessarily be perpendicular
to the orientation of the intersected mineralisation .
No significant orientation based sampling bias is known at this
time.
All reported mineralised intervals are down hole intervals
not true widths.
Sample
security
The measures taken to ensure sample
security.
Appropriate security measures are taken by Sandfire 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.
Sampling is intended. Not applicable to this release

Diamond drilling by Farm-in Partner Sandfire is on tenement
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
These tenements fall within the Department of Conservationmanaged Doolgunna pastoral lease.
All tenements are current and in good standing.
Exploration
done by other
parties
Acknowledgment and appraisal of
exploration by other parties.
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.
Geology
Deposit type, geological setting and
style of mineralisation.
Mineral
tenement and
land tenure
status
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
Yungunga-Nya Native Title Claimants and have assumed
management of Heritage Agreements which were executed
by Talisman. These agreements allow Sandfire to carry out
exploration activities on their traditional land.
Talisman’s Springfield Project lies within the Proterozoic-aged
Bryah rift basin bounded by the Archaean Marymia Inlier to
the north and the Proterozoic Yerrida basin to the south.
The principal exploration targets at the Springfield Project 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 drillholes:
easting and northing of the drill-hole
collar
elevation or RL (Reduced Level –
elevation above sea level in metres)
of the drill-hole collar
dip and azimuth of the hole
down hole length and interception
depth
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.
Refer to Table 1 of the accompanying document for details
regarding the position of drill holes.
Springfield Project Exploration Update
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.
No analyses are reported in this release
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 (e.g. ‘down
hole length, true width not known’).
Downhole intercepts of mineralisation reported in this release
are from a drill hole orientated perpendicular to a modelled EM
plate. The drill hole may not necessarily be perpendicular to the
mineralised zone. All widths reported are downhole intervals.
The geometry of the mineralisation, relative to the drill hole, is
unknown at this stage.
All intersection reported in this release are down hole intervals.
True widths are not known.
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.
Appropriate maps with scale are included within the body of
the accompanying document.
Balanced
reporting
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.
The accompanying document is considered to represent a
balanced report.
Other
substantive
exploration
data
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.
Other exploration data collected in not considered as material
to this document at this stage. Further data collection will be
reviewed and reported when considered material.
Further work
The nature and scale of planned further
work (e.g. tests for lateral extensions or
depth extensions or large-scale step-out
drilling).
Diagrams clearly highlighting the areas
of possible extensions, including the
main geological interpretations and
future drilling areas, provided this
information is not commercially
sensitive.
Sandfire advise that additional work will be planned once
analytical results are received for drill hole TLDD0004A.
