Announcement PDF 6 September 2023 RC Drilling Commences Across Multiple Lachlan Copper-Gold-Base Metal Targets in NSW Initial 7,200m of drilling planned across four large-scale targets Highlights: • Reverse Circulation (RC) drilling has commenced at four priority targets at the Lachlan Project. • Targets include the Rip & Tear, Noisy Ned, Carpina North and Durnings prospects. • Deeper RC drilling with holes up to 400m depth, will test the potential for large-scale coppergold and VMS copper-lead-zinc-silver deposits, supported by elevated soil geochemistry, geophysical anomalies and structural mapping. • The drilling campaign is designed to provide a follow-up drill test of anomalous soil geochemical results with prospective coincident geophysical anomalies generated during Talisman’s 2022 and early 2023 regional surveys, marking the beginning of an exciting and potentially transformational new phase of exploration for the Company. Figure 1 – Strike Drilling Rig mobilised to the Rip N Tear prospect. 1 Talisman Mining Limited (ASX: TLM, Talisman) is pleased to advise that it has commenced a 7,200m Reverse Circulation (RC) drilling campaign to test four high-priority prospects at its 100%owned Lachlan Project in NSW. The Lachlan Project spans the Canbelego-Mineral Hill Volcanic Belt between Condobolin and Canbelego in NSW and is prospective for large scale porphyry copper-gold and VMS style copperlead-zinc-silver deposits (see Figure 2). Figure 2 – Lachlan Project location plan highlighting prospect locations along the Canbelego Mineral-Hill Volcanic Belt. 2 Drilling has commenced initially at the Rip & Tear prospect (Figure 3), the first target to be tested for Cobar-style VMS copper-lead-zinc-silver mineralisation. The Rip & Tear prospect contains strongly anomalous base metal soil geochemistry and a series of conductive plates in interpreted structural positions adjacent to a large granite intrusion. Figure 3- Rip & Tear Prospect Oblique View looking north-east. The program will also provide an initial test of the Noisy Ned prospect, located to the north-west of Rip N Tear. Noisy Ned contains a series of strongly anomalous base metals intersections such as 112m at 0.16% Zn from surface and 21m at 0.33% Cu from 22m in NNRC00031, which require follow-up. In addition, a moderate sized Induced Polarisation (IP) geophysical anomaly has been defined below the current drilling. The Noisy Ned prospect sits within a recently surveyed large gravity low, interpreted to mark a large intrusion (see Figure 4). 1 Refer to Talisman ASX release dated 30 November 2018 for further information and JORC tables. 3 Figure 4 – Noisy Ned gravity survey anomaly target. Follow-up RC programs are also planned at the Carpina North gold prospect and the Durnings/Kaolin Shaft poly-metallic mineralised trend. Best intervals at Carpina North include 132m at 0.31g/t Au from surface in CNRC00122, while best results at Durnings/Kaolin Shaft include 8m at 6.3 g/t Au and 0.77% Cu from 82m in DRRC00013. Talisman has received the required regulatory approvals for the program areas from the relevant NSW Government authorities to progress drilling sequentially across the planned areas. Regulatory approvals have been planned and submitted based on drilling success to allow immediate follow-up of positive drill results. Talisman looks forward to completing this program by approximately late October 2023 and utilising the datasets to identify further walk-up drill targets for a second phase of drilling. 2 3 Refer to Talisman ASX release dated 26 July 2022 for further information and JORC tables. Refer to Talisman ASX release dated 15 May 2023 for further information and JORC tables. 4 Management Comment Talisman’s Managing Director, Andrew Munckton, said: “We are pleased to announce the recommencement of RC drilling at our Central Lachlan Project in NSW. The geological team have completed reviews of the Company’s larger and most attractive targets across our extensive, highly prospective gold and base metals tenure. We will test these targets with this initial phase of RC drilling before moving to other targets in the assessment pipeline.” “I anticipate that we will have a steady stream of news-flow for the remainder of 2023 as we work through the program along with ground-based geophysical and geochemical surveys designed to add and rank further targets for testing following the initial phase of drilling.” “I am confident that the renewed focus on larger, more compelling targets will stand us in good stead to deliver a significant new discovery for the Company and our shareholders.” Ends For further information, please contact: Andrew Munckton - Managing Director on +61 4 3563 5598 Nicholas Read (Media inquiries) on +61 4199 29046 This release has been authorised by the Board of Talisman Mining Limited.

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.
