Announcement PDF Talisman Mining | Suite 1, Ground Floor, 33 Colin St, West Perth 6005 ABN 71079 536 495 talismanmining.com.au ASX: TLM 15 October 2026 ASX Announcement 1 Aircore Drilling Commences at East Peak Hill Gold Prospect, NSW Follow-up drilling underway to test ~5km gold mineralised corridor adjacent to the Peak Hill and Tomingley gold districts Highlights Macquarie Projects, NSW: East Peak Hill Gold Prospect ● 2,500m follow-up aircore (AC) drilling program has commenced at Talisman’s 100%-owned East Peak Hill (EPH) Prospect, NSW. ● EPH is located to the immediate east of the Peak Hill Gold District, and south of Alkane Resources’ (ASX: ALK) Tomingley Gold Project1 (1.36Moz at 2.2g/t Au). ● This phase of AC drilling is designed to further evaluate a ~5km long gold mineralised corridor that has been identified in the previous drilling programs. Previously reported results include 3m @ 1.75g/t from 33m (EPAC0003)2 . ● The gold mineralisation has been defined along the prospective contact between a package of volcaniclastic rocks and the sedimentary Cotton Formation. This is interpreted as the same stratigraphic succession that hosts Tomingley and Peak Hill. ● The drilling program is scheduled to be completed by the end of October, with first results expected by early December. Talisman Mining Limited (ASX: TLM, ‘Talisman’ or the ‘Company’) is pleased to advise that a 2,500m AC drilling program has commenced at the Company’s 100%-owned East Peak Hill Gold Prospect, part of its Macquarie Project in NSW (Figure 1). Preparations are now also underway to commence Reverse Circulation (RC) drilling at the Company’s Sheepyard Gold Prospect, within its Lachlan Fold project portfolio, to test the deeper IP anomaly generated previously by Talisman. An RC rig has been secured, and further updates will be provided in due course on the expected commencement of this next phase of drilling. Management Comment Talisman Mining Managing Director, Todd Ross, said: “We are pleased to be back on the ground at East Peak Hill following weather-related delays that restricted access to parts of the project area for an extended period. With conditions now improved, we can progress systematic testing of this high value target along the ~5km gold mineralised corridor, a contact that hosts major deposits in the district. First results are expected in early December.” 1 Tomingley Gold Project – Geological Setting and Mineralisation. Chalmers, Ransted, Kairatis and Meates 2015.

Regional geology plan of the Junee-Narromine Volcanic Belt illustrating the gold and copper-gold deposits of the region. Talisman tenure in the belt consists of four ELs. The East Peak Hill Project is located on EL9395, approximately 10km south-east of the Tomingley Gold Operation. Aircore Drilling Program Details The current AC program will comprise up to five drill lines to test two key target areas (shown in Figure 2). EPH1 Target The EPH1 Target was defined by previous AC programs completed by Talisman. Drilling across the prospective contact intersected strongly anomalous gold values in a position that is interpreted as an area of structural complexity (“jog” structure) (Figure 3). The follow-up drill testing will step out to the north and south to test for extensions of the gold mineralisation.

Previous attempts to drill this area were impeded by significant rain events. Figure 2. Target summary plan showing previous and current drill programs.

Talisman Mining | Suite 1, Ground Floor, 33 Colin St, West Perth 6005 ABN 71079 536 495 talismanmining.com.au ASX: TLM 15 October 2026 ASX Announcement 5 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 Licences. 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 also has a significant tenement holding in both the Molong and Junee-Narromine belts within the Macquarie Arc geological domain. The Macquarie Arc hosts several of Australia’s largest gold and copper-gold discoveries and operations including Cadia Valley, North Parkes, Cowal and Tomingley. Talisman believes there is significant potential for the discovery of substantial copper and gold mineralisation within this land package and is undertaking active exploration to test a number of these targets.
