Mineral Hill Gold Bar KINGSTONRESOURCES.COM.AU | ASX:KSN 2 Important notices and disclaimer Exploration by Other Explorers This presentation contains information sourced from the reports of other Explorers. References to the original reports are provided as footnotes where the information is cited in this presentation. KSN does not vouch for the accuracy of these reports. 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. Production Target The LOM plan includes Mineral Resource Estimates for Pearse pits, the Southern Ore Zone (SOZ) and Jack’s Hut to estimate the Production Target1. All Ore Reserves and Mineral Resources underpinning this LOM plan have been prepared by Competent Persons in accordance with the 2012 JORC reporting guidelines. The Production Target comprises 51% Ore Reserves, 11% Measured & Indicated Resources and 38% Inferred Resources. The first 12 and 36 months of the Production Target are underpinned by 89% and 80% of Measured and Indicated Resources respectively. 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 forwardlooking statements included in this announcement. The detailed reasons for that conclusion are outline throughout this presentation. See ASX Announcements dated 27 June 2023, 2 April 2024 and 30 Sept 2024, for further detail and key assumptions.

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. The other original reports are available through the ASX website.

KINGSTONRESOURCES.COM.AU | ASX:KSN 21 Metal equivalents This presentation quotes metal equivalent grades for the life of mine plan, Mineral Resources and Ore Reserves. Price assumptions used are based primarily on consensus forecasts with adjustments based on company expectations. Gold equivalent (AuEq) and copper equivalent (CuEq) conversion factors are used within the announcement and are calculated by dividing price/unit for each commodity (Cu/t, Au/oz, Ag/oz, Pb/t, Zn/t) and multiplying by the metallurgical recovery. Since the metallurgical recovery varies according to deposit type, the metal equivalent factors are unique for each deposit (i.e. Open Pit, and Underground). Metallurgical recoveries are based on historical production (20102016) as well as recent metallurgical test work and are applied to the Resource and Reserve calculated grades for each commodity. The Company is of the opinion that all the elements included in the metal equivalent calculations have a demonstrated potential to be recovered and sold. Mineral Hill has a CIL circuit, Cu flotation circuit, Pb flotation circuit and Zn flotation circuit to produce three different concentrates as well as gold doré.
