June 2013 Quarterly Activities Report
- Doolgunna Copper Gold Projects
Springfield (TLM 100%)
The Springfield Project comprises a 303km² ground package located approximately 150km north-east of Meekatharra in the northern Murchison Goldfields region of Western Australia and 4km directly along strike from Sandfire Resources’ DeGrussa VMS Copper-Gold Mine (see Appendix 1).
During the June Quarter, exploration field activities at Springfield were predominantly concentrated on the Southern Volcanics region where priority target areas had previously been identified by a combination of airborne Versatile Time Domain Electromagnetic (VTEM) and ground-based electromagnetic (EM) surveys, as well as geochemical sampling derived from both soil sampling and Aircore drilling.
Southern Volcanics
During the Quarter, an 11-hole RC drilling programme was completed (for full details see Appendix 2 ) to test six targets within the Southern Volcanics, which comprise a thick sequence of prospective Narracoota basalts, volcanic sediments and dolerites in close proximity to the Goodin Fault Zone (GFZ) – a major basin boundary structure and possible focus for VHMS and other copper (+/- gold) rich mineralizing fluids.

The Reverse Circulation (RC) drilling programme tested two electromagnetic (EM) targets at The Kink prospect and a combination of four geochemical and geophysical target zones identified and validated by recently completed geophysical and geochemical surveys at the Wedge prospect (see Figure 1 ).
A single 150m RC drill-hole (SPRC315) and subsequent down-hole electro-magnetic (DHEM) survey was completed at VTEM-1 to test a modelled VTEM plate which was interpreted to be located at a depth of approximately 120m (see Figure 1 ).

June 2013 Quarterly Activities Report
Hole SPRC315 intersected siltstone and shale with fine grained mafic volcanic sediments and intercalated ferruginous shale from 108m to the end of the hole. While no sulphide mineralization was noted, the downhole EM survey detected a weakly conductive zone from 120-130m which is thought to be associated with a haematitic shale horizon; it is interpreted that the VTEM-1 anomaly is also associated with this unit. No significant assays were returned from this drilling.
At the Kink Prospect , a single RC drill hole (SPRC316) was drilled into the VTEM-2 target to test the core of a 3D EM inversion model from a recently completed FLEM survey designed to test for copper-gold mineralisation at a depth beyond the resolution of the VTEM survey (see Figure 1 ). Anomalous copper results in nearby wide-spaced aircore drilling also provided encouragement for potential mineralization in this area.
SPRC316 intersected basalt and dolerite with trace iron sulphides and magnetite in fresh rock from 74m to end-of-hole at 150m. Geophysical modelling indicates a small anomaly detected about 50m deeper than the original FLEM model and centred slightly to the south-west of the drill section. The Company has concluded that SPRC316 intersected the top of the conductor at the bottom of the hole, with the anomalous conductance related to the magnetite and iron sulphide development. No significant assays were returned from SPRC316.
At the Wedge Prospect , nine angled RC drill holes (SPRC317-SPRC325) were drilled on three traverses as part of the drill programme to test four target zones identified along the Goodin Fault Zone (see Figure 1 ). These target zones have coherent zones of elevated copper, gold and zinc values identified from recent surface lag and soil sampling, detailed surface mapping and geophysical support. Talisman considers that these zones may be related to structurally-controlled copper mineralization connected with the Goodin Fault Zone where it transgresses permissive iron and sulphide-rich host rocks.
The drilling intersected sheared mafic volcanics, dolerite, intercalated siltstone, shale and jasperoidal chert horizons with variable quartz veining throughout. Several broad zones of elevated copper and a minor gold mineralized interval were intersected and are summarized in Appendix 2 . These zones of mineralization were associated with trace copper and iron sulphides and quartz veining in altered mafic rocks. Work is ongoing to assess the significance of these results.
Other activities
An ongoing detailed technical review has highlighted that the Springfield Project may be prospective for a wide range of copper and gold mineralization styles. In addition to DeGrussa-style Volcanic-hosted Massive Sulphide (VHMS) mineralization, the Project is also considered to be prospective for structurally-controlled copper mineralization, as seen at the nearby Thaduna and Green Dragon deposits, as well as large replacement-style copper mineralization such as the Mt Isa and Nifty copper mines.
Exploration targeting tool-kits have been developed and refined to aid in the identification of potential target areas within the Springfield Project that may host structurally controlled and replacement-style copper mineralisation. These exploration tool-kits have also been developed to assist in regional business development activities.
Halloween Copper-Gold Project (TLM 100%)
The Halloween Project is located 11.5km south-west of the DeGrussa VMS Copper-Gold Mine and 16.5km west of Talisman’s Springfield Copper-Gold Project (see Appendix 1). RC and diamond drilling on 150-200m traverses has intersected structurally-controlled high-grade gold, silver and copper intercepts associated with a thickened volcano-sedimentary host unit over a strike length of over 800m.
Rehabilitation of previous ground disturbing activities was completed during the Quarter along with the assessment of previous exploration results.

Halloween West JV (TLM 60%)
Talisman holds a 60% joint venture interest in the Halloween West Project under a Farm-in Agreement with Chrysalis Resources Limited (ASX: CYS). The Project is located immediately along strike and to the west of the 100%-owned Halloween Project and is interpreted to host the western extension of the Halloween mineralized trend (see Appendix 1).
During the Quarter, Talisman entered into a formal Joint Venture Agreement with Chrysalis Resources with regard to the Halloween West Project.
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.
During the Quarter, in-fill soil sampling programmes were completed across two interpreted Proterozoic-aged mafic/ultramafic intrusions at the Kerba and Homestead Prospects . The Kerba and Homestead projects are located within a major regional shear zone and are considered prospective for magmatic/hydrothermal nickel-copper-PGE sulphide mineralization (see Figure 2 ). This work was designed to confirm and better define associated nickel-copper anomalism noted from previous geochemical sampling conducted in 2012 at the two prospects.

Kerba Prospect
Historical regional soil sampling by Talisman over the Kerba Prospect returned coherent nickel-copper-PGE anomalism over three 400m spaced lines. A detailed soil sampling program on a 100m x 50m grid was undertaken during the quarter with the aim of better defining Ni-Cu-PGE geochemical targets.
==> picture [358 x 249] intentionally omitted <==
The soil programme at Kerba has clearly defined a coherent East-West trending zone of anomalous nickel-in-soil (>1000ppm Ni) over a strike length of 1km (see Figure 3 and Appendix 3 ).
Elevated nickel, cobalt and magnesium values, and nickel / chrome ratios (>1.25) point to a high-magnesium ultramafic source (greater than 25% MgO) which indicates a potentially fertile environment for magmatic nickel sulphide accumulations.
This zone also shows coincident platinum anomalism
Figure 3–Kerba Prospect magnetic image showing nickel -in-soil anomalies over interpreted mafic-ultramafic intrusion coincident platinum anomalism (see Figure 4 ) consistently greater than 12ppb Pt that may be indicative of possible sulphide mineralization processes (see Appendix 3 ).
==> picture [362 x 252] intentionally omitted <==
Additionally, elevated copper values (>80ppm) define three discrete anomalous zones (to a maximum of 145ppm) along the northern margin of the prominent magnetic body –albeit slightly offset to the main nickel anomaly.
Importantly, these copperplatinum results may indicate possible sulphide mineralization along the basal contact of the interpreted host ultramaficmafic intrusion.

June 2013 Quarterly Activities Report
Homestead Prospect
Recent soil sampling over the Homestead Prospect detected a second discrete East-West trending coincident nickel-platinum anomaly, with a maximum nickel value of 917ppm, associated with a strongly magnetic feature that is also interpreted to be a dyke-like mafic-ultramafic intrusion. It is interpreted that highly variable transported regolith materials at Homestead may obscure its surface expression to the east of the main nickel anomaly.
Importantly, these encouraging soil geochemistry results across the Kerba and Homestead Prospects indicate the presence of high-magnesium ultramafic rocks. Combined with the presence of essential pathfinder geochemical anomalism, the Kerba and Homestead Prospects demonstrate the potential to host magmatic/hydrothermal nickel-copper-PGE sulphide mineralization.
Historic exploration data over the Kerba prospect is currently under review and further work is underway to assess the significance of the recent results with a view to planning appropriate follow-up work programmes for the second half of 2013.
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 52 km² 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.
The Muddawerrie Project comprises two mineralised trends, Mt Maitland and Muddawerrie, which extend for 6km along the western and eastern sides of the project area respectively. Both trends are characterised by highly anomalous gold geochemistry associated with highly sheared mafic/ultramafic volcanic rocks and BIF coincident with a number of old gold workings along each trend.
A reconnaissance site visit was undertaken during the Quarter to field check several gold anomalies generated by previous soil sampling campaigns.
Milgun Project (TLM 100%)
The 766km² 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 during the Quarter; however, an assessment of the Project’s gold potential was commenced.
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.
No field activities were undertaken during the Quarter.

June 2013 Quarterly Activities Report
CORPORATE
At the end of the June Quarter, Talisman held cash of $19.5 million.
In light of the challenging market conditions facing the resource sector, over the course of 2013 Talisman has implemented a number of initiatives to reduce corporate and administrative overheads as well as the rate of exploration spend in order to maintain its strong fiscal position.
In early 2013 Talisman implemented a significant reduction in staffing levels and continues to review and rationalise its organisational structure consistent with prevailing market conditions as well as the level of proposed exploration and corporate activity.
Additionally, effective from 1[st] July 2013, all of Talisman’s Directors (both executive and non-executive) and management personnel have voluntarily agreed to a 10% reduction in their salary and superannuation benefits.
Talisman also recognises that, with a relatively strong cash position and the present economic circumstances facing the resources industry, the Company is well placed to actively assess the potential acquisition of advanced, quality copper-gold assets.
