Overview

Talisman Mining Limited (ASX: TLM) is pleased to advise that Sandfire Resources NL (ASX: SFR; “Sandfire”) has reported a maiden JORC 2012 compliant Indicated and Inferred Mineral Resource for the Monty copper-gold deposit, located within the Springfield Project in WA, 10km east of Sandfire’s DeGrussa Copper-Gold Mine ( see Appendix 1 ).

The JORC Indicated and Inferred Mineral Resource is 1.05 million tonnes grading 9.4% copper and 1.6g/t gold[1] and includes a high-grade massive sulphide component of 763,000t grading 12.1% Cu and 2.1g/t Au for 92,000t of contained copper and 52,000 oz of contained gold[1] . The Mineral resource is reported by Sandfire as part of the Springfield Joint Venture

The maiden Monty Mineral Resource is an exceptionally high grade resource which has been delineated within 9 months of its discovery. It is the first deposit to be discovered outside of the DeGrussa VMS complex and, importantly, provides a proof of concept for the potential of the region to host multiple centres of VMS copper-gold mineralisation.

High level studies are now underway by the Joint Venture to investigate the optimal pathway to unlock the value of the Monty Deposit.

In addition, the Joint Venture is focusing on exploration as a priority both in the vicinity of the Monty Deposit, where it is believed that there is considerable potential to discover further VMS mineralisation, and at other emerging prospects within the Springfield Project.

Resource Estimate and Geology

The Mineral Resource estimate for the Monty Deposit was completed by Sandfire’s internal geological team, and reviewed by independent external contractors Cube Consulting. The geological model and Mineral Resource estimate were based on the data from 82 diamond drill holes completed by drilling contractor DDH1 Drilling.

The drilling was completed on a nominal 30m by 40m spacing, which has provided sufficient confidence in the model for Sandfire to classify 99% of the calculated resources into the JORC Indicated category which is available for conversion to Ore Reserve following the completion of appropriate studies.

Sandfire have advised that the resource has been estimated utilising Ordinary Kriging with parameters specific for each zone of the mineralisation including the discrete high-grade bornite domains.

The maiden Monty Mineral Resource estimate reported by Sandfire is set out in Table 1 on the following page.

Note: Mineral Resource is based on a copper cut-off of 1.0%.

Calculations have been rounded to the nearest 1000 t, 0.1 % copper grade and 1000 t copper metal, 0.1 g/t gold grade, 1000 oz gold metal, differences may occur due to rounding.

The mineralisation at Monty is contained within a host sequence of sediments and basalts and occurs as multiple sulphide lenses at different stratigraphic levels, surrounded by disseminated and/or blebby sulphides (“halo mineralisation”) in chlorite-altered host sequence litho-types.

The Monty Deposit is interpreted by Sandfire to be a Volcanogenic Massive Sulphide (“VMS”) deposit that formed during sub-sea floor replacement of the host sequence stratigraphy by mineralising hydrothermal fluids. The host sequence is bounded both above, and below, by dolerite sills.

The modelled mineralisation at Monty is contained within seven stacked lenses of massive sulphide, with over 87 % of the contained metal within two main lenses ( see Figure 1 ).

In addition to the two main sulphide lenses, five additional subordinate massive sulphide lenses have been modelled ( see Figure 2 ), along with a lower-grade geological envelope of Halo mineralisation ( see Figure 3 ).

Figure 3: Monty Resource showing internal and external ‘Halo’ lenses [1] .

Sandfire have modelled halo mineralisation, both internal to the main massive sulphide lenses and as an external skin that sits directly adjacent to the high-grade massive sulphides.

Based on the available drilling, the highly altered sulphidic halo mineralisation has been interpreted by Sandfire to extend below the limits of the modelled massive sulphide lenses (see Figure 4 ).

==> picture [319 x 256] intentionally omitted <==

Figure 4: Monty resource showing all modelled mineralisation [1] .

Talisman believes that the presence of this highly altered sulphidic halo mineralisation interpreted below the limits of the modelled massive sulphide lenses highlights the importance of the planned program of deep diamond drilling and subsequent down-hole EM geophysical survey which is aimed at testing the areas down-dip and down-plunge of the Monty Deposit.

Talisman also notes that two separate lenses of high-grade bornite mineralisation have been modelled by Sandfire within the two main lenses shown in Figure 1 . With only four holes intersecting these lenses of high tenor mineralisation, Sandfire have been careful to limit the extent of this material.

Further work is required to better define and understand the bornite mineralisation, with the Joint Venture considering further drilling as part of future studies to further understand the potential extent of the bornite mineralisation and determine if there is a strategic opportunity to mine direct shipping ore (DSO).

Next Steps at Monty

Other planned work to advance the understanding of the Monty Deposit includes a targeted structural drilling program aimed at providing detailed information to allow the development of a structural geological model to provide context on the location and setting of the Monty Deposit.

The Joint Venture has also commenced a number of high-level studies at Monty to assess potential development pathways for the project and to maximise the value of the Monty Deposit to the Joint Venture parties. This work includes:

  • Metallurgical testwork to define ore characteristics; including an assessment of suitability of the Monty ore for processing at the existing DeGrussa concentrator;

==> picture [66 x 39] intentionally omitted <==

==> picture [76 x 39] intentionally omitted <==

  • Geotechnical and hydro-geological drilling;

  • Mining studies;

  • Regulatory approvals; and

  • Infrastructure studies.

Results from these studies will be used to define the scope for further technical work and the scope of a feasibility study.

Exploration Activities

A wider program of DHEM surveys of all new RC and regional diamond drill-holes has been planned as part of a new phase of exploration now that the focus has moved away from the resource definition drillout.

Sandfire have advised that a focused exploration program outside of the Monty Deposit, aimed at testing the wider regional Springfield Project area, has now commenced or is planned to commence shortly. This work includes:

  • A systematic air-core drilling program to accurately delineate the interpreted VMS host horizon within the Monty area;

  • RC drilling (with diamond tails where required) within the interpreted VMS host horizon along strike from the Monty Deposit;

  • Diamond drilling and subsequent DHEM geophysical survey aimed at testing for potential down-dip and down-plunge extensions of the Monty Deposit;

  • RC and DHEM surveys along the Homer trend where previous shallow drilling has intersected a thick sequence of exhalative rocks interpreted to be analogous to the DeGrussa host stratigraphy; and

  • Systematic aircore drilling over the Southern Volcanic trend to accurately define the prospective VMS horizon.

Management Comment

Talisman’s Acting CEO Dan Madden said the rapid delineation of a high-grade, high quality and high value resource at Monty marked a significant milestone for the Springfield Joint Venture and an important breakthrough for the Doolgunna region.

“This is a tremendous result which gives Talisman shareholders exposure to one of the most significant new high-grade VMS copper-gold deposits to be delineated anywhere in the world in recent years, via our 30 per cent interest in the Joint Venture,” he said.

“We are looking forward to the results of the forthcoming concept studies being undertaken by the Joint Venture and to the ongoing exploration of this emerging VMS corridor, which we believe offers outstanding potential for the discovery of additional mineralisation.

“With the discovery occurring at a relatively early stage of the farm-in and the resource drillout now complete, this means that exploration activity at Springfield can now focus beyond the resource – both within the immediate environs of the deposit and further afield within the 5km long Monty corridor.

“We are very pleased to note Sandfire’s commitment to ongoing exploration in the Monty region and other exciting prospects within the Joint Venture ground, such as Homer and the Southern Volcanics, and we are all looking forward to the results of these extensive work programs.

“Following our recent highly successful capital raising, Talisman is now well-funded to underpin our contribution to the Joint Venture, both in terms of feasibility studies at Monty and ongoing exploration work across several emerging areas.

“We support Sandfire’s view that this is one of the most prospective districts for VMS exploration in the world and we believe the Joint Venture is well placed for future exploration success, now that the Monty discovery has demonstrated beyond any doubt the potential of this region to host multiple centres of mineralisation.”

No field duplicates have been taken.
The sample sizes are considered appropriate for
VHMS and Gold mineralisation types.
Quality of
assay data
and
laboratory
tests
The nature, quality and

and whether acceptable levels of
accuracy (i.e. lack of bias) and
precision have been established.
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.
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.
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.

orientation and the orientation of key
mineralised structures is considered to
have introduced a sampling bias, this
should be assessed and reported if
material.
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.
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.
No external audits or reviews of the sampling
techniques and data have been completed.
  • Coordinate and azimuth are reported in MGA 94 Zone 50.

Section 2 Reporting of Exploration Results

(Criteria in this section apply to all succeeding sections)

Criteria JORC Code explanation Commentary
Mineral
tenement
and land
tenure status
Type, reference name/number, location
and ownership including agreements or
material issues with third parties such as
joint ventures, partnerships, overriding
royalties, native title interests, historical
sites, wilderness or national park and
environmental settings.
The security of the tenure held at the
time of reporting along with any known
impediments to obtaining a licence to
operate in the area.
 Sandfire Resources NL and Talisman Mining
Limited have formed a Joint Venture which covers
Talisman’s Doolgunna Project tenements
(E52/2282, E52/2313, E52/2466 and E52/2275).
Sandfire and Talisman hold a 70%:30% interest
respectively in the Joint Venture, with the
exception of tenement E52/2275 where interests
of approximately 81%:19% respectively are held.
Both parties are contributing proportionately to
expenditure.
Sandfire Resources NL has been appointed as the
Joint Venture Manager.
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 Yungunga-
Nya 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.
Exploration
done by
other parties
Acknowledgment and appraisal of
exploration by other parties.
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.
Geology Deposit type, geological setting and style
of mineralisation.
 The 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:
oeasting and northing of the drill hole
collar
oelevation or RL (Reduced Level –
elevation above sea level in metres)
of the drill hole collar
odip and azimuth of the hole
odown hole length and interception
depth
ohole 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.

No new drilling information is listed in this
release.
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 length-
weighted 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.

Relationship
between
mineralisatio
n 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’).

No new drilling information is listed in this
release.
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.
Reporting of grades is done in a consistent
manner.
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 is not considered
as material to this document at this stage. Further
data collection will be reviewed and reported when
considered material.
