Announcement PDF ASX/Media Announcement 7 May 2024 Increase in Contained Gold and Silver at Pearse North Updated open pit mineral resource estimate at Mineral Hill Highlights • MRE for Pearse North increased for gold and silver by 30% and 67% respectively to 292kt @ 3.2 g/t Au and 34 g/t Ag for 30 koz of gold and 318 koz of silver. • Greater confidence in the deposit’s continuity: Review of the orientation of mineralisation shows greater spatial continuity than previously modelled. • Optimising the mine plan for current gold prices: The planned pit design is being re-optimised to take advantage of current gold prices. Kingston Resources Limited (ASX:KSN) (“Kingston’, or ‘The Company’) is pleased to announce an updated JORC 2012 Mineral Resource Estimate (MRE) for the Pearse North of 292kt @ 3.2 g/t Au and 34 g/t Ag for 30,000 oz of gold and 318,000 oz of silver. This update is supported by additional drilling data that was acquired in 2023 and the refinement of the geological interpretation. In comparison to the 2022 MRE for Pearse North, contained gold and silver has increased 30% and 67% respectively. This update presents a significant opportunity to take advantage of recent momentum in the gold price. Mining at Pearse North is scheduled to commence in the current quarter. An update of the pit optimisation and mine design with this MRE is currently underway. Gold and silver production from the Pearse pits is expected to have a material impact on Kingston’s balance sheet. Further updates will be provided when the updated mining schedule is finalised. The refurbishment of the processing plant is progressing on time and budget in readiness for treatment of the gold ore from the Pearse deposits.

Kingston Resources Managing Director, Andrew Corbett, comments: “We are excited about the transition from tailings mining to open pit mining at our Pearse North Project. This shift will allow us to significantly expand our gold production over the coming year, while also increasing operating cash flow. The high-grade nature of the pits and the momentum in the gold price provide a strong backdrop for maximising margins from this highly lucrative resource. The entire technical team has done a fantastic job ensuring the Project has access to high-quality Mineral Resources and Ore Reserves necessary to support a successful Mine Plan.” ASX: KSN Shares on Issue: 633.7M Market Cap: A$42.5M Cash: (8 April 2024) A$10.7m 202/201 Miller Street, North Sydney, NSW 2060 +61 2 8021 7492 info@kingstonresources.com.au www.kingstonresources.com.au @KSNResources Mineral Resource Estimate The Pearse North deposit at Mineral Hill is interpreted to be a stacked set of shear-hosted gold-silver (AuAg) lodes within the Late Silurian to Early Devonian Mineral Hill Volcanics. The sulphide mineralisation, comprising predominantly pyrite, arsenopyrite and stibnite, is typically disseminated within quartz-mica (sericite) schist. The modelling of the mineralisation at Pearse North has been revised, using the drill hole data acquired by Kingston in the 2023 geotechnical drilling program. The significant intercepts in this round of drilling showed that the lodes have a steeper dip and greater continuity along strike than previously interpreted. The geometry of mineralisation was interpreted by creating 3D wireframe models using a 0.5g/t Au lower cutoff (previously 2g/t) leading to a better defined lode model and associated significant increase in tonnage and contained metal. Grade estimation was undertaken using ordinary kriging estimate methodology into a 3D block model. Figure 1: Plan view of the Pearse North mineralisation wireframes. www.kingstonresources.com.au 2 Classification of the MRE into confidence categories has been completed based on distance to samples and the average slope of regression. Indicated portions have a distance to the nearest sample of <25m and a slope of regression > 0.7, while Inferred portions have an average distance to samples > 30m and slope of regression < 0.6. Mineral Resources are reported at a 1.0g/t Au cut off within a Whittle optimisation shell using metal pricing of AUD$3200/oz for gold, AUD$37/oz for silver, and cost and recovery data sourced from the operation at Mineral Hill. Drilling methods in the dataset comprise reverse circulation (RC) and diamond core (DDH). Reverse circulation drilling samples were collected at 1m intervals directly from the rig cyclone (with a cone splitter attached). The diamond core was cut and sampled, with half core sample lengths ranging from 0.3m to 1.0m. Samples were analysed at SGS laboratory using Multi element 4-acid digest and gold by Fire Assay technique with an Atomic Absorption Spectrometry (AAS) instrument finish. KSN utilised QAQC in the form of standards, blanks and duplicates to ensure all data was of suitable quality for inclusion in the estimate. No specific metallurgical assumptions were made in the preparation of this MRE. Pearse North is scheduled to be mined in parallel with Pearse South, which also contains a high grade gold and silver resource. The Mineral Resources for Pearse South are shown in Error!

The Company’s objective is to establish itself as a midtier gold and base metals company with multiple producing assets. Mineral Hill Mine, NSW (100%) • • • • • Mine plan out to the end of 2027: Open pit and underground mining. Significant upside: Current life of mine only utilises 22% of the current 8.9Mt of Mineral Resources. Infrastructure excellence: Extensive existing infrastructure with all permits and approvals in place. Exploration potential: Exceptional upside within current Mining Leases (ML) and Exploration Licenses (EL). Current Focus: Completion of the Tailings Project gold production, transitioning to open pit mining at Pearse and production of concentrate for sale. Misima Gold Project, PNG (100%) • • • • • DFS Validation: potential for a robust, scalable, and low-cost open pit operation. Production Potential: Anticipated gold production of ~2.4Moz over a 20-Year Mine Life (Avg. 128kozpa). Strong Financial Viability: Pre-Tax Net Present Value (NPV) of A$956 Million (based on a US$1,800/oz Gold Price). Gold Price Upside: Highly leveraged to the upside of the gold price, amplifying potential returns. Current Focus: Prioritising ESIA reports, strategic funding & development strategies. Mineral Hill is a gold and copper mine located in the Cobar Basin of NSW. In June 2023, the company updated its life of mine plan, including both open pit and underground mining until 2027. The processing plant currently operates a CIL, and work is well advanced to recommission the existing crushing, grinding and flotation circuits for copper, lead and zinc concentrate production. In addition to current production, the company is focused on meeting near mine production targets located on the existing MLs. The aim is to extend the mine’s life through organic growth and consider regional deposits that could be processed at Mineral Hill’s processing plant. Misima hosts a JORC Resource of 3.8Moz Au and an Ore Reserve of 1.73Moz. Placer Pacific operated Misima as a profitable open pit mine between 1989 and 2001, producing over 3.7Moz before it was closed when the gold price was below US$300/oz. The Misima Project also offers great potential for additional resource growth through exploration success targeting extensions and additions to the current Resource base.

JORC Code explanation Criteria Mineral tenement and land tenure status • • Commentary Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. • • Quintana holds a 2% Net Smelter Return (NSR) royalty over production at the Mineral Hill Mine. Exploration done by other parties • Acknowledgment and appraisal of exploration by other parties. • Coincident Au-As soil anomalism and low-grade Au-Ag mineralisation was discovered at Pearse North by Triako Resources Ltd in the 1990s. 50m+ spaced drilling at the prospect by Triako during the period 1999-2005 included several intercepts of significant Au grade. Follow-up drilling by KBL Mining Ltd in 2010 served to better define a number of high grade lenses at the prospect. KBL released a Resource and Reserve in 2016 incorporating new drill results and geology modelling. JORC Code explanation Criteria Commentary Geology • Deposit type, geological setting and style of mineralisation. • The Pearse North deposit at Mineral Hill is interpreted to be a shear-hosted Au-Ag within the Late Silurian to Early Devonian Mineral Hill Volcanics, a pile of proximal rhyolitic volcaniclastic rocks with minor reworked volcaniclastic sedimentary rocks. The sulphide mineralisation, comprising predominantly pyrite, arsenopyrite and stibnite, is typically disseminated within quartz-mica (sericite) schist. At the Pearse deposit to the south, analysis by Laser Ablation ICP-MS has found that fine-grained gold is mostly concentrated in arsenopyrite and fine-grained ‘spongy’ (melnikovite) pyrite with lower concentrations of gold hosted by crystalline pyrite. Petrological analysis of drill core confirms that mineralisation at Pearse North has similar characteristics to that at Pearse South. Drill hole Information • A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.

The assumptions used for any reporting of metal equivalent values should be clearly stated. These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or Commentary • 98% of drilling was approximately perpendicular to the overall strike of mineralisation. • Geotechnical drill holes were orientated at oblique angles to the mineralised trend but normal to potential pit wall design orientations. • Exploration results not being reported • See the body of reports for maps, diagrams, and tabulations. • Exploration results not being reported • Arsenic, Antimony and Sulphur are deleterious elements at Pearse North.

The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. • The geological confidence is considered to be moderate to high. • The mineralised volume at Pearse North has been based on a drill section interpretation of mineralisation defined by a lower limit gold grade of 0.2 g/t Au, along with the observed close association between mineralisation and the structural interpretations. • Nine mineralisation domains have been defined including a low-grade domain defined by all Au assay values above a 0.2 g/t cut-off. Internal to this domain are eight high-grade domains included Au values above a 0.5 g/t cut-off. These domains represent clearly defined breaks in the mineralisation and represent the spatial geometry and continuity of mineralised structures. • Drill hole spacing within the main resource area was mostly completed on a 20 metre by 20 metre drill pattern. • The factors affecting continuity both of grade and geology are most likely to be associated with structural controls and local complexity. The broad approach to the mineralisation modelling is an attempt to model an unbiased interpretation. • The geological model has improved since the 2022 MRE through a process of implicit modelling of Au-As-Sb and other associated elements, that was conditioned by geological mapping, drill core observations, and orientated structures in drill core; followed by explicit modelling/domain interpretation. A greater degree of confidence has been achieved. • The high grade gold mineralisation identified varies from 5 m to 50 m in width and goes to a depth of 150 m below surface along the 225 m strike length drilled to date. The zone strikes 5⁰ to the north-east and dips steeply to the west. 11 Criteria JORC Code explanation Estimation CRITERIA and modelling techniques • • • • • • • • • • • www.kingstonresources.com.au The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points.

Commentary • Grade estimation for Gold, Silver, Arsenic, Sulphur and Antimony were completed using Micromine software. Geostatistical analysis and variography were completed using Snowden’s Supervisor v8 software. • Using parameters derived from modelled variograms Au, Ag, As, S and Sb grade data were interpolated into 10 mE x 10 mN x 5 mRL sized panels using Ordinary Kriging (OK). Surpac software was used for the estimations. Three dimensional mineralised wireframes were used to domain the data. Sample data was composited to 1 m down hole lengths using the best fit method. • The influence of extreme grade values was addressed by reducing high outlier values by applying top-cuts to the data and constraining their influence to 15m during estimation. These top-cut values were determined through statistical analysis (histograms, log probability plots, coefficients of variation and summary multi-variate and bi-variate statistics). A visual 3D inspection of the relative location of grade outliers and highergrade samples was conducted. • Down hole and directional variograms were modelled using normal score transformations of the skewed data sets for each element. Nuggets were low to moderate. Variogram analysis was confined to the main lodes with parameters applied to adjacent lodes and search ellipse parameters adjusted to match the individual lode geometry. • Scatter plots and regression analysis was completed on the main domains to review the relationship between the Au and Ag, As, S and Sb variables. Due to the low-to-moderate correlation Cube has used separate variograms for the variables for each domain; however, the search parameters are the same to ensure some level of consistency between Au, Ag, As, S and Sb interpolations. • Work was undertaken in the previous estimate using kriging neighbourhood analysis (KNA) on several test areas within the domains to determine the optimal parent block size and number of informing samples for estimation. A minimum of 8 and maximum of 16 samples per block were used for the estimation The ellipsoid search parameters were based on the variogram ranges, with the search ellipse dimensions similar to the variogram range, with anisotropies retained. Hard boundaries were used between the high and low grade domains for the estimate. • Octant restrictions were not used, and estimates were into parent blocks, not sub-blocks. Search ellipse rotation directions were the same as for the variograms. A first pass of 40 m was used with 82% of blocks in the main lodes estimating on the first pass. A second pass was used to fill remaining blocks which doubled the search distance but maintained all other parameters. Distance limiting (15m) was used to ensure high grade values didn’t have a greater spatial influence than is warranted. • A three-step process was used to validate the model. A qualitative assessment was 12 Criteria JORC Code explanation Commentary completed by slicing sections through the block model in positions coincident with drilling. A quantitative assessment of the estimate was completed by comparing the average grades of the declustered composite file input against the block model output for all the resource objects. A trend analysis was completed by comparing the interpolated blocks to the sample composite data within the main lodes. This analysis was completed for strike, cross-strike and elevations across the main lodes at each deposit. Validation plots showed good correlation between the composite grades and the block model grades. CRITERIA Moisture • Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. • Tonnages and grades were estimated on a dry in situ basis. No moisture values were reviewed. Cut-off parameters • The basis of the adopted cut-off grade(s) or quality parameters applied. Mining factors or assumptions • Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis • A nominal lower cut-off grade of 0.2 g/t Au was used to define the mineralised envelope that encompasses the complete mineralised distribution and produce a model that reduces the risk of conditional bias that could be introduced where the constraining interpretation and data selection is based on a significantly higher grade than the natural geological grade cut-off. • The cut-off grade for reporting (above 1.0 g/t Au) was used in line with the previous resource reporting and is based on the results of Whittle optimisation shells using cost and recovery data sourced from the operation at Mineral Hill. • Open pit mining optimi
