Lachlan Copper-Gold Project, NSW
The 100%-owned Lachlan Project spans the Canbelego-Mineral Hill Volcanic Belt between
Condobolin and Canbelego in NSW and is prospective for polymetallic epithermal and volcanic
hosted (Cu, Pb, Zn, Au, Ag), orogenic (Au) and intrusion related (Cu, Au) deposits (see Figure 1).
A comprehensive geological, geochemical and geophysical review across all TLM Mineral HillCanbelego Volcanic Belt (MHCVB) tenure was completed during the Quarter.
The review identified two high priority targets in the Walkers Hill gold geochemical trend scheduled for
initial Reverse Circulation (RC) drilling to begin in mid-July.
The review also identified multiple untested areas of soil/regolith within prospective parts of the
MHCVB that require geochemical infill sampling (Geochemical Gaps) (Figure 2). A 1,600-hole auger
program is also scheduled to commence in July targeting these areas.

Walkers Hill
The Walkers Hill geochemical trend, the largest in the district, comprises an extensive gold-in soil
anomaly, of approximately 10km by 2.5km of which approximately 4.5km is within Talisman tenement
EL 8571 (see Figure 2 and Figure 3).
Several stages of exploration have been undertaken since 2000 by Triako Exploration, Paradigm
Resources and Talisman Mining to advance the understanding of this high-priority geochemical trend.
Historical exploration results within the Walkers Hill trend include1:
•
1,250 soils taken at the Sheepyard and Maroonbah Targets between 2003 and 2008. These
results show distinct coherent soil anomalies for Au (>20ppb) and As (>150ppm). See Figure 3.
• RC drilling
o 40m at 0.46 g/t Au from 3m (PMV005) and 12m at 0.38g/t Au (TMY027) from surface at
Sheepyard1.
o 20m at 0.48 g/t Au from 16m (TBC015) and 5m @ 0.54 g/t Au from 14m (TBC016) at
Maroonbah (TBC015) 1.
o All mineralised holes ended in oxide and drilling was limited to 60m below surface.
• Pole Diploe Induced Polarisation (PDIP) geophysical survey completed by Talisman in 2023
revealed a chargeability anomaly below mineralised RC drill intercepts at the Sheepyard target
(Figure 4).
Talisman is scheduled to commence RC drilling at the Sheepyard Target in late-July.
Planned RC drilling will consist of four RC holes up to 200m deep testing the large PDIP anomaly
situated below historical anomalous drill intercepts (see Figure 4) including 40m at 0.46g/t Au within
the oxide zone of hole PMV005.
At completion of the Sheepyard Target drilling, ground geophysical surveying at Maroonbah Target and
further reconnaissance of the Walkers Hill geochemical gold trend will commence with the objective
of undertaking further drilling in the September 2025 Quarter.

Macquarie Arc Projects, NSW
Yarindury (EL 9679) – Geophysical survey
Yarindury is located 30km north-east of Dubbo within the Molong Volcanic Belt, which forms part of
the Macquarie Volcanic Arc in central-western NSW. The tenement lies along the same prospective
corridor as Alkane Resources’ (ASX: ALK) Boda–Kaiser Project, 20km to the south-east, and
Newmont’s (NYSE: NEM) world-class Cadia copper-gold mine, located 100km along strike to the
south (Figure 5).
Talisman’s planned exploration program over the second half of CY2025 includes a three-line, 13km
long, IP (Induced Polarisation) and MT (Magnetotelluric) ground geophysical survey whichcommenced
in July. The survey is targeting prominent magnetic anomalies in the south-eastern portion of the
tenement, where historical drilling indicates basement depths of approximately 200m.
Drill testing of targets generated from this survey is planned for the September 2025 Quarter (Figure
6).

East Peak Hill (EL 9395) – Auger Drilling
EL 9395 is located in central western NSW zone on the Junee–Narromine Volcanic Belt (JNVB) of the
Macquarie Volcanic Arc. The JNVB extends over 200km north–south and its northern portion hosts
Alkane Resources’ (ASX: ALK) Tomingley Gold Mine (shear hosted vein deposits) and the Peak Hill
high-sulphidation-epithermal gold deposit. The EL is situated immediately south-east of the
Tomingley gold mine.
Talisman interprets East Peak Hill to be highly prospective for orogenic shear-hosted vein style gold
mineralisation, high sulphidation vein style gold and porphyry style copper-gold mineralisation.
East Peak Hill Project contains interpreted andesitic volcanic units striking north–south along the
length of the tenement.
An initial scout 150-hole auger survey commenced in May 2025, targeting areas of shallow to
moderate cover. Any material copper or gold anomalies identified by the survey will be followed up by
AC or RC drilling in the September-October 2025 period (Figure 8).

Gawler Craton – South Australia
Mabel Creek – June half drilling results
Talisman acquired 100% ownership of the Mabel Creek IOCG Project in June 2023, securing a
1,048km² landholding approximately 30km west of Coober Pedy. The project is located over the post
mineral covered parts of the Northern Gawler Craton, spanning the Nawa Domain and Mount Woods Coober Pedy Ridge Complex. These geological domains are separated by a major east–west trending
structural corridor known as the Karari Shear and Horse Camp Fault (Figure 9).
The Gawler Craton is highly prospective for large-scale Iron Oxide Copper Gold (IOCG) systems and
hosts world-class deposits such as Olympic Dam, Carrapateena, and Prominent Hill, as well as
recent discoveries including Oak Dam and Emmie Bluff.
Figure 7: Simplified regional geology of the northern Gawler Craton showing Mabel Creek project area,
major structural geological features and mineral deposits.
Following a detailed ground gravity survey completed in 20242, Talisman conducted an initial diamond
drilling program in March–April 20253. Three holes (MCMRD001–MCMRD003), totalling 1,367m were
completed which tested near-coincident magnetic and gravity anomalies under post mineral cover, in
the Nawa Domain north of the Horse Camp Fault (Figure 10 and Figure 11).

Basement rocks were intersected at expected depths of between 205m to 305m. Diamond drilling
intersected a suite of metamorphic lithologies including granite gneiss, pegmatitic granite,
amphibolite and calc-silicate rocks, with variable levels of hydrothermal alteration observed in most
holes.
The results from hole MCMRD002, which tested anomaly P2 adjacent to the Horse Camp Fault were
encouraging. This hole intersected a broad hydrothermal alteration zone with elevated molybdenum
(Mo) and rare earth elements (REE)4.
The significance of this zone as a potential vector toward IOCG mineralisation is being assessed
further via detailed geochemical, petrological and geochronological studies.
The tenure remains prospective for IOCG-style mineralisation.
Following a review of the data, the area south of the Horse Camp Fault with likely shallow post mineral
cover, has been identified as an exploration priority where several near-coincident magnetic and
gravity anomalies are located within the Mt Woods-Coober Pedy Ridge Complex. A second phase of
exploration drilling is planned.
Ongoing geophysical modelling, incorporating insights from the initial drilling is underway to refine
target drill hole locations.

Iron Ore Royalty
During the quarter, Talisman received $1.579 million in royalty payments from iron ore sales that
occurred between 1 March 2024 and 31 May 2025 from Wonmunna Iron Ore Pty Ltd (Wonmunna), a
wholly owned subsidiary of Mineral Resources Limited (ASX: MIN), the owner and operator of the
Wonmunna Iron Ore Mine (WIOM) in the Pilbara region of Western Australia.
The iron ore royalty receipts for the current quarter reflect the impact of moderating global iron ore
pricing on WIOM sales made during the quarter, unfavourable $A: $US exchange rate movements and
lower than average shipping volumes from Wonmunna.
Since the commencement of iron ore production at the WIOM in March 2021, total royalty payments
of $31.3 million have been received by Talisman as at the date of this announcement.
New Project Opportunities
The Company continued to review potential mineral growth opportunities in Australia and elsewhere.
Talisman continues to adopt a judicious approach to the review of all growth opportunities to ensure
only value-accretive transactions that have the potential to create long-term shareholder value are
pursued.
Cash Balance
At 30 June 2025, Talisman had $4.492 million cash available for its operating and investing activities.

About Talisman Mining
Talisman Mining Limited (ASX:TLM) is an Australian mineral development and exploration company. The
Company’s aim is to maximise shareholder value through exploration, discovery and development of
complementary opportunities in base and precious metals.
Talisman has secured tenements in the Cobar/Mineral Hill region in Central NSW through the grant of its own
Exploration Licenses and through a joint venture agreement. The Cobar/Mineral Hill region is a richly mineralised
district that hosts several base and precious metal mines including the CSA, Tritton, and Hera/Nymagee mines.
This region contains highly prospective geology that has produced many long-life, high-grade mineral
discoveries. Talisman has identified several areas within its Lachlan Cu-Au Project tenements that show
evidence of base and precious metals endowment which have had very little modern systematic exploration
completed to date. Talisman believes there is significant potential for the discovery of substantial base metals
and gold mineralisation within this land package and is undertaking active exploration to test a number of these
targets.
Talisman also has secured access to over 1000 km2 of highly prospective tenure in South Australia’s Gawler
Craton known as the Mabel Creek Project. Mabel Creek is prospective for large scale Iron Oxide Copper Gold
(IOCG) deposits and intrusion related rare earths and battery metals mineralisation. Mable Creek is surrounded
by similar tenure owned and being actively explored by Australia’s biggest resource companies including BHP,
Rio Tinto and FMG.

Appendix 2
JORC Tables Section 1 & 2
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
Criteria
JORC Code explanation
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.
•
Drilling
techniques
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 3kg 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.
•
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, face-sampling bit or
other type, whether core is oriented
and if so, by what method, etc).
Commentary
•
RC Drilling samples are collected at either one
metre or two metre intervals via a drill rig
mounted cyclone and static cone splitter set to a
12% split to produce a nominal 4-7kg sample
which are collected in a pre-numbered sample
bag.
•
RC samples undergo routine 2 metre composite
pXRF analysis using an Olympus Vanta M-series
to aid in logging and identifying zones of interest.
•
Diamond drill core samples, either PQ, HQ3 or
NQ2 in size diameter, are either cut in half
longitudinally or a quarter longitudinally, using an
automated Almonte core saw with core placed in
boats, holding the core in place. Core sample
intervals varied from 0.2 to 1.3m in length but
were predominantly aligned to 1m intervals or
with sample boundaries which respected
geological contacts.
•
Sampling is controlled by Talisman protocols and
QAQC procedures as per industry standard and a
chain of custody maintained through transfer to
ALS Laboratories in Adelaide, SA.
•
RC/DD samples are dried, crushed (where
required), split and pulverised (total prep) to
produce a master pulp. From this master pulp, a
0.25g sub sample was taken for multi-element
analysis by four acid digest with an ICP-MS finish.
A 50g sub sample was also taken for fire assay for
gold with ICP-AES finish.
•
Mud Rotary (MR) chips will be sampled from
sieved 6m composites and will be analysed using
a portable XRF.
•
RC drilling cited in this report was undertaken by
Strike Drilling Pty Ltd using a LC36 (KWL 700)
truck-mounted Reverse Circulation drill rig. A
truck-mounted booster and compressor provided
high pressure air with an auxiliary compressor
used where ground conditions warranted.
•
RC drilling was completed with a face sampling
hammer of nominal 140mm size
•
Diamond Drilling cited in this report at the
Durnings Project was undertaken by DDH1

whether sample bias may have
occurred due to preferential loss/gain
of fine/coarse material.
•
Diamond drilling undertaken by DDH1 Drilling Pty
Ltd Multipurpose UDR1000 truck mounted rig at
Mabel Ck and Yarindury. Mud Rotary drilling was
completed through the thick (~200-300m)
Mesozoic and/or Palaeozoic cover sequences.
Diamond drill tails were undertaken in the
basement sequence when intersected.
•
Down hole surveys were undertaken
approximately every 30m using an Axis north
seeking gyro.
RC Drilling
•
RC drill sample recovery is generally high with
sample recoveries and quality recorded in the
database by the logging geologist
•
Sample recoveries were monitored in real-time by
the presence of Talisman personnel at the drill
site.
Diamond Drilling
•
Core recovery data recorded for each run by
measuring total length of core retrieved against
the downhole interval drilled and stored in the
database. TLM representatives continuously
monitor core recovery and core presentation
quality as drilling is conducted and issues or
discrepancies are rectified promptly to maintain
industry best standards.
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.
RC Drilling
•
•
RC logging records lithology, mineralogy,
mineralisation, alteration, structure, weathering,
colour and other primary features of the rock
samples and is considered to be representative
across the intercepted geological units.
Whether logging is qualitative or
quantitative in nature. Core (or
costean, channel, etc.) photography.
•
RC logging is both qualitative and quantitative
depending on the field being logged.
•

RC Drilling
•
RC samples were dried, crushed (where
required), split and pulverised (total prep) to
produce a 0.25g sub sample for base metal
analysis or a 30g sub sample for gold analysis by
fire assay.

•
QAQC protocols for all RC sampling involved the
use of Certified Reference Material (CRM) as
assay standards.
•
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 insitu material collected, including for
All QAQC controls and measures were routinely
reviewed. Sample size is considered appropriate
for geochemical sampling for base-metal and
gold mineralisation given the nature of drilling and
anticipated distribution of mineralisation. Field
duplicates were collected at a 1 in 30 sample rate
