Talisman Mining Limited – Springfield Exploration Update
==> picture [45 x 46] intentionally omitted <==
Talisman Mining Ltd (ASX: TLM) is pleased to provide an update on ongoing exploration activities at the Company’s flagship Springfield Copper-Gold Project , where five specific horizons have now been identified which are prospective for VMS-style mineralisation.
The Springfield Project comprises a 303km² ground package located approximately150km north-east of Meekatharra in the northern Murchison Goldfields region of Western Australia ( Figure 1 ). The project is located immediately along strike to the east of Sandfire Resources’ DeGrussa Project, where mineral resources now stand at 14.33Mt @ 4.6% Cu and 1.6g/t Au contained in four deposits and mine development is underway.
The strength, size and grade of the DeGrussa Volcanogenic Massive Sulphide (VMS) system support Talisman’s view that the exploration potential in this region and more importantly, immediately within the Company’s Springfield Project – located just 4km to the east of the DeGrussa Deposits – is very high.
OVERVIEW
Talisman has been aggressively exploring the Springfield Project since the grant of the first two project tenements in November 2009, with systematic exploration activities focused initially on the generation of high quality data sets capable of targeting VMS mineral systems.
This data is being used to develop a fully-integrated 3D geological model for the Springfield area with emphasis on identifying stratigraphic, structural and geochemical controls on VMS mineralization and to generate robust targets for drill testing.
Importantly, this systematic and fundamental approach to exploration has now identified what are interpreted to be five specific stratigraphic horizons prospective for the development of VMS mineral systems ( Figure 2 ).
The target horizons are typically identified by highly-anomalous copper-gold-zinc geochemistry and associated with extensive epidote-magnetite-hematite alteration.
At a number of prospects (e.g. Homer and Monty) significant copper-iron sulphides (i.e. chalcopyritepyrite) have been intersected in drilling, both as widespread disseminations and localised breccia-stringer mineralisation.
This style and strength of alteration and the widespread presence of copper-iron sulphides suggests that very active VMS mineralising processes have been in place at the Springfield Project.
Work to date has delineated these target horizons over a combined strike length of approximately 35 to 40km.
Exploration activities at Springfield are presently focussed on diamond and reverse circulation drilling, supported by down hole electromagnetic (DHEM) surveys, of specific, discrete targets along these target horizons.

MONTY PROSPECT
Diamond drilling at the Monty Prospect has now defined a prospective VMS stratigraphic horizon over a strike length of at least 1.6 kilometres and potentially up to 3 kilometres based on the interpretation of geophysical and geochemical data in the southern portion of the Prospect ( Figure 3 ).
Recent assay results from drill hole SPD023 have confirmed that the horizon remains open to the east with the intersection of a narrow zone (~0.25m) of quartz-sulphide (chalcopyrite-pyrite) mineralisation in this targeted position.
The mineralised zone returned final assay results of ( see Table 1 for details ):

Talisman believes that these drilling results are highly encouraging and have defined an extensive stratigraphic horizon prospective for VMS deposits ( Figure 4 ).
Recent diamond drilling in the north of the Monty Prospect has targeted a series of discrete geophysical anomalies along the geochemically fertile northern margin of the Prospect at a contact between mafic volcanic rocks and an underlying dolerite-sediment package.
Drilling at this position has intersected widespread zones of strong hematite-magnetite alteration with minor disseminated chalcopyrite.
This contact, which has an interpreted strike length up to 10 kilometres, is likely to be the equivalent position to the Cow Bore Prospect, held by Resource and Investment NL (ASX: RNI), where significant gold-copper results have been announced by that Company.
Programs of diamond and RC drilling, supported by DHEM, across the two Monty VMS horizons are in progress.
HOMER PROSPECT
The systematic exploration approach undertaken by Talisman in obtaining detailed geological data at the Homer Prospect has enabled the Company to compile a 3D geological model of that Prospect.
This 3D geological model has confirmed an analogous setting to Sandfire’s DeGrussa deposits, with highly sheared mafic volcanics, dolerites and sedimentary horizons hosting copper-iron sulphides along an interpreted paleo-seafloor position that is interpreted to extend for at least 7km within Talisman’s project area.
In addition, geochemically anomalous zones associated with jasperoidal chert horizons have been identified.

HOMER PROSPECT (Continued)
This work confirms that Homer represents a highly prospective VMS horizon warranting further exploration.
The next phase of exploration at Homer, which is currently underway, is planned to test a series of structural targets and associated copper anomalies with RC drilling along this prospective northern VMS horizon.
Additionally, recent drilling and interpretation has confirmed that the southern portion of the Homer prospect, with an interpreted strike length at least 4 kms, is likely to be the equivalent position to the Red Bore Prospect held by Thundelarra Exploration Limited (ASX:THX), where significant gold-copper results have previously been announced.
This confirms an additional prospective VMS horizon for future targeting.
Follow-up diamond drilling and associated DHEM surveys will be planned in the future at Homer as required.
Additionally, a third phase of RAB drilling (150 holes for 10,000m) is scheduled to commence in late September to test the northern portion of the Springfield Project ( Figure 3 ). These RAB drill holes, which will be drilled along eight 500m spaced traverses, are designed to test for prospective VMS stratigraphy and mineralization in interpreted structurally repeated positions to the north of Homer.
ABRAHAM PROSPECT
Recent geological interpretation of the Abraham Prospect in the southern portion of the Springfield Project ( Figure 2 ) has potentially identified an additional prospective stratigraphic position for VMS mineralisation.
Follow up assessment of this Prospect is planned for 2012.
GEOPHYSICS
A comprehensive Moving Loop Electro-Magnetic (MLEM) survey has recently been completed with data gathered along 200m spaced lines over most of the Northern and Central Corridors.
Results from this survey are currently being assessed, but it is likely that a number of conductive anomalies identified to date will justify drill testing in the future once data is fully assessed and regulatory approvals achieved.
