ASX Announcement

Aircore drilling delivers strong near surface gold results at Sheepyard – Walkers Hill Project, NSW

15m at 1.10g/t Au from surface and 9m at 1.05g/t Au from 30m within a broader mineralised zone

Highlights:

Lachlan Projects, NSW

Walkers Hill Gold Project

• Aircore (AC) drilling completed recently at the Sheepyard Prospect has intersected a broad zone of shallow gold mineralisation containing several intersections of higher-grade gold, with assay results including:

• SYAC0043

  • 15m at 1.10g/t Au from surface including 6m at 1.95g/t Au ; and

• SYAC0041

  • 9m at 1.05g/t Au from 30m; and

• SYAC0040

  • 6m at 0.63g/t Au from 54m to end-of-hole

• Sheepyard forms part of the larger Walkers Hill gold-in-soil anomaly, sitting on a major geological contact and stretching over 4.5km north-west of the recent drilling.

• Sheepyard contains three NE-SW oriented, higher tenor geochemical trends within the broader anomalous soil geochemistry.

• The recent 2,229m AC program tested these geochemical trends, with two lines spaced 200m apart which penetrated to a vertical depth of generally 25m to 50m.

• The higher-grade intersections occur within a sequence of five consecutive drill-holes (SYAC0040 to SYAC0044), which collectively indicate a significant zone of anomalous near-surface gold mineralisation approximately 60 metres wide (True width not known).

• The higher-grade zones are coincident with sheared, altered, quartz-veined and occasionally brecciated quartz which strike in NE-SW direction and dip steeply north-west.

• Further AC drilling is planned to test extensions of the broad mineralised zones intersected in the initial two lines of drilling.

Talisman Mining (ASX: TLM , ‘Talisman’ or ‘the Company’) is pleased to report assay results from the 2,229m Aircore (AC) drilling program completed late last year at its Walkers Hill Gold Project, located approximately 60km north-west of Condobolin in NSW.

Walkers Hill Project (EL 8571) – Background[1]

The Walkers Hill Project contains the extensive Walkers Hill gold-in-soil trend, extending over an area of approximately 4.5km by 2.0km. The Sheepyard prospect lies at the south-eastern end of the Walkers Hill trend and displays gold-in-soil anomalism over an area of 1.5km by 1.0km.

Historical and earlier Talisman exploration results[1] from shallow depths indicate the presence of broad zones of gold mineralisation with narrower zones of higher-grade gold (see TLM ASX announcements 17 June, 25 July and 15 September 2025) at the Sheepyard Prospect (Figures 2 and 3).

Recent AC Drill Program Results

During November 2025, Wallis Drilling (Figure 1) completed a total of 49 Aircore (AC) holes for 2,229m in two lines spaced 200m apart to test the southern part of the soil geochemical trend at Sheepyard (Figures 2, Figure 3, Table 1 and Table 2).

Drilling was angled at 60 degrees grid south and penetrated the Oxide and Transitional Zone of weathering to the top of fresh rock at approximately 30m-60m down-hole (25m-50m vertical). Sampling was undertaken on 3m composite samples for each drill hole and assayed for gold. Hand-held XRF results were also collected for pathfinder elements – Arsenic, Antimony and Tungsten – to assist with trend interpretation. Assaying of 3m composites for gold reported in this announcement are by 50g Fire Assay.

The AC drilling intersected a broad zone of gold mineralisation in the Western Line of AC drilling and a lesser zone of mineralisation in the Eastern Line. Gold mineralisation is reported from several consecutive holes, particularly on the Western Line. Results are reported by 3m composite sample and include:

1 ASX: TLM – 17 June, 25 July and 15 September 2025.

Western Line

• SYAC0040 – 6m at 0.63g/t Au from 54m to end-of-hole

• SYAC0041 –

• 9m at 1.05g/t Au from 30m

• SYAC0043 – 15m at 1.10g/t Au from surface including 6m at 1.95g/t Au

• SYAC0044 – 21m at 0.38g/t Au from surface

Eastern Line

• SYAC0022 – 6m at 0.47g/t Au from 39m to end-of-hole

• SYAC0024 – 6m at 0.69g/t Au from 21m

Surface mapping and geological logging show that shallow gold mineralisation within the Ordovician-age Girilambone metasediments occurs in association with sheared, veined and occasionally brecciated quartzpyrite alteration zones, interpreted to be in broad, north-east trending fault zones (Figure 2 and 3).

Deeper gold mineralisation encountered in RC drilling further north is associated with thin quartz veining and selvedge disseminated pyrite mineralisation[1] .

Gold mineralisation is associated with anomalous arsenic, antimony and tungsten, typical of orogenic-style gold sulphide mineralisation[1] . The AC drilling program targeted higher tenor soil anomalies which mark higher-grade mineralisation in the near-surface oxide environment.

The Western Line of AC drilling (Figure 3 and Figure 4) shows a broad zone of near-surface gold mineralisation which contains a coherent zone of higher grade intersected in five consecutive holes, SYAC0040 to SYAC0044.

The Western Line higher grade zone spans a distance of approximately 60m (true width not known) and contains both higher grade intersections (9m at 1.05g/t Au from 30m in SYAC0041 and 15m at 1.10g/t Au from surface in SYAC0043) which correspond to a zone of altered, quartz veined, pyrite-rich and sheared sediments interpreted to be a NE-SW trending shear zone emanating from the interpreted position of the Erimeran Granite contact, located approximately 600m south-west of the Western Line of AC drilling

Interpretation and Next Steps in the Exploration Program

The Western Line of AC drilling indicates significant widths of near-surface gold mineralisation containing zones between 6m and 15m wide (true width not known) of >1.0g/t Au gold mineralisation within the broader 60m zone. The higher-grade zones intersected to date are interpreted to trend NE-SW.

The overall trend of the 4.5km-long anomalous soil geochemistry within the greater Walkers Hill area trends NWSE and is proximal to and strongly associated with the mapped contact between the large Erimeran Granite intrusion and the host rock Girilambone Sediments.

Additional mapping and soil geochemical sampling programs are planned at Maroonbah 3km north-west of Sheepyard to bring further detail to this association.

A follow-up program of two additional lines of AC drilling further west of the Western Line will be undertaken once access to Maroombah and additional soil geochemical programs have been completed later in 2026 to test the extent of the higher-grade mineralisation intersected to date.

Management Comment

Talisman’s Managing Director, Andrew Munckton, said: “We are very encouraged by the recent shallow AC drilling results at Sheepyard. Both lines of AC drilling intersected shallow zones of gold mineralisation that coincide with sheared and altered sediments, rich in quartz veining and pyrite mineralisation. These zones are interpreted as a late-stage, NW-trending fault zone that is mapped by surface quartz veining and the strongest arsenic and gold anomalies seen in the soil geochemistry.

“Importantly, in the Western Line of AC drilling, the broader zone of gold mineralisation contains a number of higher-grade intersections such as 15m at 1.1g/t Au from surface in SYAC00043 that indicate both the presence of ore grade mineralisation at surface and the potential for these higher-grade zones to persist along strike to the south-west and at depth below the oxide zone tested in this round of drilling.

“The next steps in the exploration program at the greater Walkers Hill project include additional geological mapping and soil geochemistry surveys at Maroonbah followed by further lines of AC drilling at Sheepyard, stepping-out in a westerly direction to confirm the extent of the higher grade near-surface mineralisation as we approach the regionally important contact with the Erimeran Granite to the west.

“This AC drilling program has shown significant zones of ore grade gold mineralisation at surface and opened up the entire 4.5km-long zone of surface gold anomalism stretching from Sheepyard to Maroonbah, and which follows the Erimeran Granite contact, for follow-up exploration.

“Sheepyard remains a small part of the much larger Walkers Hill soil anomaly. The Maroonbah Prospect to the north-west of Sheepyard appears to be the larger and stronger soil anomaly and we are looking forward to accessing this for initial exploration work in 2026.”

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 1040 km[2] of highly prospective tenure in South Australia’s Gwaler 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. Mabel Creek is surrounded by similar tenure owned and being actively explored by Australia’s biggest resource companies including BHP, Rio Tinto and FMG.

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 (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. • 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.
