Mr Munckton is a full-time employee of Talisman Mining Ltd and has sufficient experience relevant to the style of mineralisation and types of deposits under consideration, and to the activities undertaken, to qualify as a Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code). Mr Munckton has reviewed the contents of this presentation and consents to the inclusion of the matters based on his information in the form and context in which they appear. No new information that is considered material is included in this presentation. All Exploration Results referred to have previously been released to the ASX and are appropriately referenced. The Company confirms that it is not aware of any new information or data that materially affects the Exploration Results included in those announcements. JORC Tables are not considered necessary for the purposes of this presentation. Au Equivalent Gold Equivalent calculation is based on Gold and Copper prices as at 30 June 2026 of USD $4,060/ oz of Gold and USD $ 13,400/ tonne of Copper. Metallurgical recoveries are assumed to be equivalent to published recent Cadia Valley recoveries of 80% for gold and 85% for Copper. Au Eq ounces of gold is calculated as ounces of gold plus tonnes of copper * ((13400*0.85)/(4060*0.80)) ounces of gold
