March 2014 Quarterly Activities Report
- Exploration Farm in Joint Venture with Sandfire Resources NL
In December 2013, Talisman secured the involvement of leading Australian copper producer Sandfire Resources NL (ASX: SFR) in the next phase of exploration of its Doolgunna copper-gold projects through a $15 million exploration farm-in joint venture (refer ASX release 20/12/2013). The Letter Agreement covers Talisman’s interests in the Springfield , Halloween and Halloween West JV Projects.
Talisman’s Springfield Projec t lies immediately along strike, to the east; from Sandfire’s operating DeGrussa Copper-Gold mine, and the Halloween and Halloween West JV Projects abut Sandfire’s Doolgunna Project to the west ( see Figure 1 ). These Projects are interpreted to contain extensions of the volcanic rock package which hosts the DeGrussa VMS deposits. The exploration farm-in enables the two companies to work together and share local exploration knowledge in order to target potential copper-gold discoveries at these projects.

Talisman has invested more than $20 million exploring its Doolgunna Projects over the past four years. During this time, it has assembled a comprehensive geo-scientific database which has facilitated the identification of a series of highquality copper-gold exploration targets, especially across the Springfield Project and within the interpreted extension of the DeGrussa Mine Corridor ( see Figure 1 ).
Following the completion of the Exploration Farm-in Joint Venture Agreement, Talisman provided a copy of its extensive, high-quality datasets to Sandfire. Full integration, processing and evaluation of these datasets by Sandfire is now well advanced with a focus on identification of initial priority target areas along the extended DeGrussa Mine Corridor and across the greater Doolgunna Projects.
Importantly, Sandfire has already identified a combined 65km strike length of prospective Volcanogenic Massive Sulphide (VMS) horizon across the combined Talisman and Sandfire tenements, providing a significantly expanded search horizon for potential new VMS deposits ( see Figure 1 ).

March 2014 Quarterly Activities Report
Sandfire is undertaking a technically driven and systematic approach to the detailed assessment of Talisman’s Doolgunna Projects datasets with the involvement of both Talisman personnel and external expert consultants supporting its in-house exploration team. Work known to have been undertaken, planned or underway by Sandfire on Talisman’s Doolgunna projects is as follows.
Lithochemical Targeting
Detailed geochemical analysis of the DeGrussa copper-gold mineralisation has enabled Sandfire to develop a robust set of geochemical pathfinder elements (Principal Components) with a unique metal signature. When combined in this way the lithochemical data provides a powerful tool to better detect DeGrussa-style mineralisation and host rocks and to prioritize highly-prospective areas for further drilling and ground electromagnetic surveys.
A preliminary evaluation of the Talisman data has indicated that there is likely to be several prospective areas across the Doolgunna Projects, however further assaying of Talisman drill samples is required in order to identify the critical pathfinder elements used to “fingerprint” the DeGrussa signature.
This work is currently underway and will provide an important input for determining the overall prospectivity along the DeGrussa VMS Trend.
Geophysical Evaluation
Another critical step towards robust new target generation is the compilation, integration and evaluation of the Talisman geophysical datasets.
The Talisman magnetic and gravity data is of a very high quality and resolution allowing more precise interpretation and mapping of the key units and target horizons along the DeGrussa Trend into the Springfield Project. Sandfire has developed a strong understanding of the geology at DeGrussa and now using the Talisman geophysical data is in a position to extend its interpretation across the entire combined Doolgunna Project.
While Talisman has gathered extensive first-pass Moving Loop Electromagnetic data over the Springfield Project, further scope remains to apply the latest high-energy Fixed Loop and Downhole electromagnetic techniques over well-defined VMS targets.
Sandfire have demonstrated considerable capability with the successful discovery of the “blind” C4 and C5 mineralised shoots at DeGrussa using these high-energy electromagnetic methods and it has the ability to apply these same techniques over targets on the Doolgunna JV Projects once all the data has been compiled and the revised geological and geochemical interpretations are at hand.
Targeting and Drilling
First drilling under the new exploration farm-in agreement is anticipated to commence in the second half of 2014. As discussed above, Sandfire is currently working towards fully integrating and re-interpreting the extensive Talisman datasets. This work is highly likely to build-on Sandfire’s growing understanding of the controls and location of the DeGrussa mineralisation and potentially lead to new VMS copper-gold targets amenable to detailed ground electromagnetic surveys and direct drill testing.

March 2014 Quarterly Activities Report
- Halloween West JV Soil Sampling
During the December Quarter and prior to the exploration farm-in agreement with Sandfire, Talisman undertook another phase of exploration at the Halloween West JV ( Talisman ~63%; Chrysalis Resources Ltd ~37% ). This comprised approximately 800 soil samples taken along 100m and 200m-spaced soil sampling traverses.
The exploration program was designed to test for the surface expression of copper-gold mineralization across two previously defined target areas including the western extension of the Halloween VMS target horizon at the Wizard Prospect and a malachite-bearing (secondary copper) sedimentary horizon in the east of the tenement at the Malachite Prospect (see Figure 2 ).
==> picture [502 x 313] intentionally omitted <==
Figure 2: Halloween West JV Project showing recently completed soil sampling program over the Wizard and Malachite Prospects
At the Wizard Prospect, a zone of coherent copper-gold anomalism was defined and correlates with the interpreted western extension of the prospective Halloween volcano-sedimentary corridor. Maximum assay results returned were 90.3ppm Cu against a background 25–40ppm Cu and a peak 447.9ppb Au against a background < 2 ppb Au (see Figure 3 , Appendix 2 ).
At the Malachite Prospect, copper-gold anomalism was confirmed as occurring across the general area surrounding a known malachite occurrence. Maximum assay results returned were 103.7ppm Cu against a background of 25–40ppm Cu and a peak of 72.5 ppb Au against a background of background < 2 ppb (see Figure 3 , Appendix 2 ).
==> picture [612 x 41] intentionally omitted <==
March 2014 Quarterly Activities Report
Geological mapping at the Malachite Prospect indicates that the surface copper-gold anomalism is associated with a copper-bearing inter-volcanic sedimentary horizon and as such may warrant further mapping and geochemical evaluation to determine its possible extents and significance.
==> picture [503 x 303] intentionally omitted <==
Figure 3 – Halloween West JV copper results for soil sampling programs at the Wizard and Malachite Prospects
The next phase of activity at the Halloween Projects, which is now underway, will involve a process of integration, analysis and modelling of the combined exploration data sets by Sandfire. Once complete, this will then enable planning of the next phases of exploration at the Halloween West Project. Talisman’s share of future exploration activities on this Project will be funded and managed by Sandfire under the terms of the Letter Agreement.
Murchison Exploration Projects
Livingstone Project (TLM 80%)
The Livingstone Project is located approximately 130km to the north-west of Meekatharra (see Appendix 1) and covers an area of 208 km². The Project straddles the western extension of the prospective Bryah Basin at the northern margin of the Yilgarn Craton. A major shear zone traverses the entire Project with widespread gold intercepts returned by historic percussion drilling programs over a strike length of more than 31km.

March 2014 Quarterly Activities Report
Kerba Ni-Cu-PGE Prospect
The Kerba Prospect comprises an interpreted ovoid Proterozoic-aged mafic-ultramafic intrusion localised along the major regional Kerba Fault Zone (see Figure 4 ). The principal exploration target at Kerba is Voisey Bay (or Nova)-style magmatic nickel-copper-PGE sulphide mineralization associated with the basal contact of the host mafic-ultramafic intrusion.
An initial 4-hole RC drilling program for 983 metres was completed in November 2013 to test for the presence of nickel sulphide mineralisation as well as to establish a platform for deeper down-hole electromagnetic (DHEM) surveying. This work was previously reported on in Talisman’s December 2013 Quarterly Report.
Importantly, petrographic examination of the drill chips noted widespread sulphide development within the mafic-ultramafic lithologies. Minor blebs of chalcopyrite and pyrite are preferentially developed in the pyroxenite unit and trace, fine-grained nickel sulphide (pentlandite) was observed at a pyroxenite-peridotite contact and it is interpreted that these sulphides were the result of localized (hydrothermal) remobilization from olivine rich phases at depth.
Down-hole electromagnetic (DHEM) surveys were completed on all holes, with no significant conductors detected.
Elevated nickel (>0.3% Ni) and copper (>300 ppm Cu) drill results were returned from the saprolite horizon above the nickel-sulphide bearing ultramafic contact, with a best intersection of 6m @ 0.47% Ni from 6m depth in LVRC001.
While these elevated results in the near-surface environment are the result of weathering processes, it was interpreted that they may also provide a useful vector to primary nickel-copper sulphides at depth elsewhere in the Kerba intrusion.
During the Quarter an external expert review was undertaken in order to assess the results of the recent drilling programme at the Kerba Prospect and to determine the validity of conducting further exploration at the Prospect.
It was concluded that the Kerba intrusion represents a fractionated ultramafic body comprising a basal peridotite grading upwards into more iron-rich pyroxenite and high-Mg basalt. It appears that much of the observed copper sulphide is hosted by the upper pyroxenite indicating normal fractionation processes, rather than massive nickel sulphide development.
However, the review also highlighted that the basal contact of the main peridotite body lies to the south of the current drilling and as such remains untested (See Figure 4 ).
Further mapping and surface geochemistry is under consideration to check for evidence of nickel sulphide accumulation along this untested basal contact position.

Muddawerrie Gold Project (TLM 80%)
The Muddawerrie Project is located approximately 100km north-west of Meekatharra in the Murchison Region of Western Australia (see Appendix 1). The Project covers an area of approximately 52km² and comprises a prospective Archaean greenstone belt with significant potential to host high-grade, banded iron formation (BIF) and mafic-hosted shear zone gold deposits, similar to those at Mt Magnet and Meekatharra.
There were no field activities conducted at Muddawerrie during the Quarter; however various desktop activities were undertaken.
Previous detailed soil sampling by Talisman has identified widespread gold anomalism at Muddawerrie.
A field visit is planned for the June 2014 Quarter and exploration programs are currently being prepared and may include drill testing of the better targets identified at the Project.

March 2014 Quarterly Activities Report
Milgun Project (TLM 100%)
The Milgun Project is located approximately 20km north west of the Shelby Project and covers a potential northern outlier of the Bryah Basin (see Appendix 1). The Milgun Project is interpreted to be located within a tectonically uplifted block of Bryah basement rocks. It is interpreted that basement uplift is an effective mechanism for focused fluid flow and possible copper-gold and gold mineralisation.
No field activities were conducted at Milgun during the Quarter.
A field visit is planned for the June 2014 Quarter to conduct further mapping and to “ground-truth” geophysical targets and previously identified geochemical copper-gold anomalies.
Shelby Project (TLM 100%)
The 1,816 km² Shelby Project is located along the northern margin of the Bryah Basin approximately 30km north of the Horseshoe Lights Copper-Gold Mine (see Appendix 1). On the basis of its geological setting, Talisman has identified the Shelby Project as having the potential to host large Iron OxideCopper-Gold (IOCG) deposits (e.g. Olympic Dam, Prominent Hill) and/or a Voisey’s Bay-style maficultramafic intrusive hosted nickel-copper-PGE sulphide deposit.
An ongoing review is focused on better defining potential geophysical targets along the interpreted northern Marymia Margin for possible follow-up exploration activities including detailed gravity and drilling.
Consideration is also being given to the potential for joint venturing this Project.
CORPORATE
At the end of the Quarter, Talisman held cash of $16.6 million.
Business Development
Having secured external exploration funding for its Doolgunna Copper-Gold Projects as a consequence of the recent exploration farm-in agreement with Sandfire, Talisman is strategically positioned to attempt to secure new, high-quality exploration assets.
During the March Quarter, Talisman’s business development activities were focused on the identification of potential quality exploration projects located within Australia for further assessment. Principal commodities under consideration are nickel sulphide, copper-gold and gold.
Of the exploration projects identified during the Quarter, assessment and initial investigation activities were conducted on 16 copper-gold projects, 18 nickel sulphide, 6 gold and 2 base metals exploration projects. (see Figure 5 )

Detailed technical and commercial due diligence activities were undertaken during the Quarter and continue on several of these exploration projects.
Investment & Royalty Update
During the Quarter, ASX listed resources company, Ochre Group Holdings Limited (“Ochre” - ASX: OGH) announced that it had agreed to sell the Wonmunna Iron Ore Project, located in the Pilbara region of Western Australia to Ascot Resources Limited (“Ascot” - ASX: AZQ) – refer OGH & AZQ announcements on 18 March 2014 .
Talisman holds 35 million ordinary shares in Ochre . This investment was acquired by Talisman in early 2011 as part consideration for the sale of the Wonmunna Iron Ore Project to Ochre at that time. This shareholding currently represents approximately 5.85% of Ochre’s issued capital.
Proposed Transaction Details ( -OGH & AZQ announcements on 18 March 2014- )
Reported consideration payable by Ascot to Ochre for the Wonmunna Iron Ore Project comprises:
-
the issue of 88 million fully paid ordinary Ascot shares (post a two for one consolidation of Ascot shares);
-
based on a minimum of a $10.0 Million in fund raising by Ascot, a A$2 million cash consideration is payable on completion;
-
Subject to various conversion conditions, a further A$29.75 million payable five years from transaction completion and at a coupon rate of 5.88% PA; and
-
a 1% gross revenue royalty commencing 12 months after the first shipment.
Should the proposed transaction and fund raising by Ascot complete successfully Ochre anticipates holding approximately 50% of Ascot’s adjusted issued capital and to have two representative directors on the Board of Ascot.
==> picture [612 x 41] intentionally omitted <==
March 2014 Quarterly Activities Report
Royalty
As part of the sale of the Wonmunna Iron Ore Project to Ochre, Talisman was also granted by Ochre a 1% gross revenue royalty from all metals mined from that project. Talisman understands that Ascot will assume Ochre’s obligation to Talisman for this 1% gross revenue royalty upon completion of the proposed transaction between Ochre and Ascot.
Potential Value Accretion
Based on historical studies on the Wonmunna project, Ascot is proposing to establish a 5Mtpa operation in the medium term which will target the production of both lump and fines products. (-AZQ announcements on 18 March 2014 and 25 March 2014-)
Assuming the transaction between Ochre and Ascot is completed and should Ascot proceed to successfully develop and operate the Wonmunna Iron Ore Project, it is possible that Talisman may potentially receive value from:
-
the receipt of a future revenue stream from the Wonmunna Project in the form of the gross revenue royalty; plus
-
a potential increase in its investment in Ochre as a result of a potential share price re-rating of Ochre, commensurate with Ochres interest in Ascot if/ when development milestones are achieved by Ascot.

Appendix 4 - 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 (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. |
781 soil samples were taken on a 100m x 25m north-south oriented grid pattern across the interpreted Halloween Target Horizon. The spacing was increased to 200m over the far eastern extents of the target horizon where its location is less well defined. |
| • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Samples were only taken from erosional or residual areas amenable to_in situ_soil sampling. No samples were taken from areas covered by alluvial deposits. |
|
| • 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. |
Soil samples were taken for assay by scraping an area of 1m x 1m to remove surficial material. A 25cm deep was dug and a sample taken and dry sieved at the sample site to collect ~100g of <2mm sample. |
|
| Drilling techniques |
• Drill type (eg core, reverse circulation, open- | No drilling reported |
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 ifso, by what method, etc). |

All soil samples were sieved dry through a 2mm sieve to collect 100gof sample for analysis. |
||
| • For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
The sample preparation of soil samples follows industry best-practice for sample preparation involving splitting, sieving, drying, and pulverizing of the total sample. |
||
| • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. |
Field QC procedures for all soil sampling programs involve the use of Certified Reference Material (CRM) as assay standards. The insertion ratio of standards was 1:20. All QC/QA controls and measures are routinely reviewed and reported on at the completion of the programme. External laboratory QC/QA checks are routinely monitored and stored in the Talisman database. |
||
| • 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. |
No field duplicates have been taken. | ||
| • Whether sample sizes are appropriate to the grain size of the material being sampled. |
Soil sample size is considered adequate for the sampling media, mineralisation style and purpose of this program. |

|---|---|---|
| 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. |
Soil sampling at Halloween West was conducted on tenement E52/2275. This lease is the focus of a Joint Venture between Talisman (61%) and Chrysalis Resources (39%). The tenement is located 150km north-east of Meekatharra, WA and falls within the Department of Conservation-managed Doolgunna pastoral lease. |
| • The security of the tenure held at the time of reporting along with any known impediments to obtaining a license to operate in the area. |
E52/2275 at Halloween West Springfield expires on the 8th February 2014. An Extension-of-Term has been granted and the tenement is in good standing with no existing impediments to exploration, |

| Geology | • Deposit type, geological setting and style of mineralisation. |
Talisman’s Halloween West 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 rocks comprise dolerites, basalt, and volcanic–derived sediments of the Narracoota Formation. The principal exploration targets in the Springfield area are Volcanic Hosted Massive Sulphide (VHMS) and structurally-controlled base metal (copper) deposits with associated gold mineralisation. |
| Drill hole Information |

| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly | No drilling results reported |
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’). |
