Exploration by Other Explorers This presentation contains information sourced from the reports of Other Explorers.

KSN has taken the decision to include this information as it is in the public domain and as we assess it to be of relevance to shareholders and investors. www.kingstonresources.com.au I ASX: KSN Corporate Presentation August 2023 2 Important Notices and Disclaimer Underground Production Target The LOM plan includes Mineral Resource Estimates from the Southern Ore Zone (SOZ) and Jack’s Hut to estimate the Production Target. All Ore Reserves and Mineral Resources underpinning this LOM plan have been prepared by Competent Persons in accordance with the 2012 JORC reporting guidelines. Probable Ore Reserve provides 46% of the total LOM processing plant feed tonnage. The Underground production target is based on Mineral Resource estimates and comprises Measured (7%), Indicated (31%), Inferred (56%) and unclassified (6%) material. There is a low level of confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the production target itself will be realised. The stated production target is based on the Company’s current expectations of future results or events and should not be solely relied upon by investors when making investment decisions. Further evaluation work and appropriate studies are required to establish sufficient confidence that this target will be met. The Company notes that the Project forecasts a positive financial performance and is therefore satisfied that the use of Inferred resources in production target reporting and forecast financial information is not the determining factor in overall Project viability and that it is reasonable to report the LOM plan with Inferred Resources. The Company has concluded that it is has a reasonable basis for providing the forward-looking statements included in this announcement. The detailed reasons for that conclusion are outline throughout this presentation. www.kingstonresources.com.au I ASX: KSN Corporate Presentation August 2023 3 Company vision Becoming a leading ASX-listed mid-tier gold and copper producer, pioneering excellence and delivering sustainable value to stakeholders Producing gold & silver at Mineral Hill, generating excellent cash flows Management team; jurisdictional experience and a track record of success Strategic asset location in NSW, with an operating mill and all MLs/permits.

Parkers Hill 2004 KBL 13/09/2011 Anthony Johnston KBL Competent Person’s Statement – Ore Reserve Reported in Accordance with JORC Code – Mineral Hill The Ore Reserve and Mineral Resources estimates were prepared by a Competent person in accordance with the JORC Code 2012 with exception of the Parkers Hill Mineral Resource Estimates that have been prepared by a Competent Person in accordance with the JORC Code 2004 and have not been updated to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported. Pearse, Parkers Hill, Jacks Hut and the Southern Ore Zone Mineral Resource estimates and Ore Reserves have been adjusted by mining depletion using the production wireframes created by the site survey department at the time of mining. These wireframes represent the mining activities at these deposits to the best of Kingston’s knowledge although they are not to be viewed as complete or accurate in their entirety and therefore mining depletion may be revised when Kingston is able to produce revised determinations on more complete data and verification thereof. Information pertaining to Mineral Resource Estimates (MRE) and Ore Reserves (OR) in this presentation has been previously released to the public. The tables on this page indicate the authors of the historical Resources/Reserves and the dates they were initially published. Kingston is not reporting these estimates as its own with exception of the MRE and OR for the TSF which has not been reported previously by any other company.
