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 forward-looking statements included in this announcement. The detailed reasons for that conclusion are outline throughout this presentation. SOZ Underground diamond drilling 1.

Mr Hayward has sufficient experience in the style of mineralisation and types of deposit under consideration and to the activity he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the ‘Australian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr. Hayward confirms that the information in the market announcement provided is an accurate representation of the available data and studies for the material mining project and consents to the inclusion in the report of the matters based on his information in the form and context in which it appears. All Mineral Resource estimates were prepared and first disclosed under the JORC Code 2004 and are an accurate representation of the available data and studies for the Mineral Hill Mine. This information has not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported. Work will commence on close of acquisition by the Company to bring each of the Mineral Resources into line with the JORC Code 2012. • 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. The other original reports are available through the ASX website. • The Competent Person signing off on the the overall Pearse Opencut Ore Reserves Estimate is Mr John Wyche BE (Min Hon) BComm CP, of Australian Mine Design and Development Pty Ltd, who is a Fellow of the AusIMM and who has sufficient relevant experience in operations and consulting for open pit metalliferous mines.

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 (2010-2016) 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. CuEq Recovered (%) = (Cu x 0.809) + (Au x 0.500) + (Ag x 0.005) + (Pb x 0.178) + (Zn 0.167) Commodity Unit Price Deposit Commodity Recovery (%) CuEq Factor Gold US$/oz 2,236 Underground Gold 76 0.500 Silver US$/oz 27.6 Silver 64 0.005 Copper US$/lb 4.95 Copper 81 0.809 Lead US$/lb 1.09 Lead 79 0.175 Zinc US$/lb 1.37 Zinc 60 0.167 www.kingstonresources.com.au I ASX: KSN Corporate Presentation | July 2025 25 Mineral Hill – Resources & Reserves Attractive commodity base with significant growth potential Total Probable Ore Reserves Measured Resource Inventory Kt Au (g/t) Ag (g/t) Pearse South 140 4.30 85 19 383 Southern Ore Zone 233 2.01 11 1.2% Pearse North 240 3.20 33 25 255 TOTAL 233 2.01 11 1.2% 700 1.40 20 0.8% 1.9% 1.6% 30 450 5.5 13 11 1,080 2.2 31 0.8% 1.9% 1.6% 74 1087 5.5 13 11 Deposit Southern Ore Zone TOTAL Cu % Pb % Zn % Au (Koz) Ag (Koz) Cu (Kt) Pb (Kt) Zn (Kt) Total Mineral Resources Deposit Pearse South • • • • • Kt 204 Au (g/t) 3.77 Ag (g/t) Cu % Pb % Zn % 70 Au (Koz) 25 Ag (Koz) Cu (Kt) Pb (Kt) Zn (Kt) 456 Deposit Kt Au (g/t) Ag (g/t) Cu % Pb % Zn % Au (Koz) Ag (Koz) Cu (Kt) Pb (Kt) Zn (Kt) 0.2% 0.4% 15 80.9 3 1 1 0.5% 0.4% 15 81 3 1 1 450 28 Indicated Resource Inventory Pearse South 164 4.10 85 22 Pearse North 270 3.20 34 28 297 Southern Ore Zone 1,667 1.37 23 1.0% 2.1% 1.7% 73 1,233 16 36 Jack's Hut 608 1.53 7 1.3% 0.5% 0.4% 30 134 8 3 2 Parkers Hill 1,793 0.191 42 1.3% 2.1% 0.9% 11 2,443 23 38 16 TOTAL 4,501 1.13 31 1.1% 1.9% 1.1% 164 #### 47 77 46 Pearse North 292 3.18 34 30 318 Southern Ore Zone 3776 1.83 17 1.0% 1.3% 1.1% 222 2017 37 51 40 Jack's Hut 1640 1.25 20 0.9% 0.8% 0.6% 66 1051 15 14 10 Parkers Hill 1843 0.19 43 1.3% 2.1% 0.9% 11 2520 23 39 17 Inferred Resource Inventory TOTAL 7,755 1.42 26 1.0% 1.4% 0.9% 354 6,364 75 104 67 Pearse South 40 2 5 3 6 Pearse North 22 2.92 29 2 21 Southern Ore Zone 1,876 2.22 12 0.9% 0.8% 0.6% 134 706 18 14 11 Jack's Hut 1,032 1.09 28 0.7% 1.0% 0.8% 36 917 7 11 8 Parkers Hill 50 0.20 48 0.7% 1.8% 2.4% 0.3 77 0.4 1 1 3,020 1.81 18 0.9% 0.9% 0.7% 175 1,727 25 26 20 Corporate Presentation | Nov 2024 26 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 Estimate, which 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 South, Parkers Hill 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.
