This release has been authorised by the Board of Talisman Mining Limited. 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. 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.
