Mineral Hill Processing Plant 2 KINGSTONRESOURCES.COM.AU | ASX:KSN KINGSTONRESOURCES.COM.AU | ASX:KSN 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 forward- looking statements included in this announcement. The detailed reasons for that conclusion are outline throughout this presentation.

Mr. Stuart Hayward is a full-time employee of Kingston Resources Limited. Mr. Hayward has sufficient experience relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking 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’. 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 this report of the matters based upon the information in the form and context in which it appears. The Company confirms that the form and context in which the Competent Person’s findings are presented have not been materially modified from the original report. 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. 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 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. Mr Wyche consents to the inclusion in this report of the information pertaining Mineral Hill Pearse open pit Ore Reserves in the form and context in which it appears. The Competent Person signing off on the overall underground SOZ Ore Reserves Estimate is Mr Steven Weckert BE ME (Min) CP, of Australian Mine Design and Development Pty Ltd, who is a Member of the AusIMM and who has sufficient relevant experience in operations and consulting for underground metalliferous mines. Mr Weckert consents to the inclusion in this report of the information pertaining to the Mineral Hill SOZ Ore Reserve in the form and context in which it appears. Kingston is not aware of any new information or data that materially affects the information included in this announcement. All material assumptions and technical parameters underpinning the Mineral Resource estimates and production targets continue to apply and have not materially changed. 17 Mineral Resource Ore Reserve Deposit JORC Ed.

Price assumptions used are based on market consensus forecasts with adjustments to account for reasonable prospects for eventual economic extraction (RPEEE), as guided by JORC reporting guidelines. Gold equivalent (AuEq) and copper equivalent (CuEq) conversion factors are used within the presentation and are calculated by multiplying the grades for each contributing metal by their respective metal price and recovery and dividing by the multiplication of the primary metal’s price and recovery (gold or copper for AuEq and CuEq respectively). 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 is currently producing metal concentrates and dore (from the CIL) on site. Upon the commencement of underground polymetallic production, the Company will have a Cu flotation circuit, Pb flotation circuit and Zn flotation circuit to produce three different concentrates as well as precious metal dore.
