The drilling was designed to increase drill density and confirm the existing geological interpretation in areas being evaluated for potential future underground mining. 8 September 2026 2 KINGSTONRESOURCES.COM.AU | ASX: KSN The results summarised in Table 1 support the existing geological interpretation and provide additional confidence in the location, continuity and grade tenor of mineralisation around the conceptual stope areas targeted by the program. Managing Director and CEO, Andrew Corbett commented: “We are aiming to make Jack’s Hut our second underground ore source at Mineral Hill. These results confirm the location of the mineralisation where we expected it and give us greater confidence in the existing conceptual stopes. We will now incorporate the drilling results into an updated resource model and mine-planning work. The surface drilling we are about to undertake is very exciting! The holes are a large step out from the existing resource and will test the potential down dip extensions. We see an opportunity to test Jack’s Hut for extensions at depth and along strike. Jack’s Hut has its own underground portal and decline, separate from the Southern Ore Zone and we see this as a significant operational benefit and something that could support an expansion in production.” Table 1: Selected significant intersections from Jack’s Hut infill drilling.

The key zones along the Jack’s Hut trend (north to south) consist of: • Ashes - gold-silver-arsenic sulphide mineralisation hosted in shears and breccias within the hanging wall of Jack’s Hut. • Jack’s Hut - copper-gold sulphide mineralisation hosted in veins and breccia infill, commonly associated with quartz, pyrite and chalcopyrite. • Iodide - polymetallic lead-zinc-silver-copper-gold mineralisation occurring as vein and breccia infill and replacement mineralisation. The drilling reported in this announcement is located at the southern end of Jack’s Hut, approaching the Iodide zone. The results support the existing interpretation of two components to the main lode: an eastern copper-gold-dominant component and a western component with elevated lead, zinc and silver. Chalcopyrite, galena and sphalerite are the dominant economic minerals often occurring in bands. Mineralisation and alteration are frequently associated with shearing and quartz veining. The program returned significant downhole intersections of up to 15m, broadly supporting the interpreted location and grade tenor of mineralisation in the targeted areas. KSNDDH093 illustrates the style of polymetallic mineralisation encountered in the area, as shown in the core photographs in Figure 5. The hole returned 9.30m @ 3.08% Pb, 3.62% Zn, 0.97% Cu, 0.71g/t Au, 15g/t Ag from 180.1m (3.2% CuEq). The surface drill rig is expected to arrive at Mineral Hill in October 2026 to test potential extensions below the existing Jack’s Hut Mineral Resource. The infill results will be incorporated into an updated geological model, with an updated Jack’s Hut Mineral Resource estimate targeted for the March quarter of 2027. 4 KINGSTONRESOURCES.COM.AU | ASX: KSN Figure 1: Plan view of the Jack’s Hut Infill drill holes.

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. Copper equivalent (CuEq) conversion factors are used within the announcement 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 copper price and copper recovery. 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 fully approved mine and processing plant, capable of producing metal concentrates and dorѐ (from the flotation and CIL circuits). The Company is targeting a recommencement of mining and processing to produce copper, lead and zinc concentrates as well as precious metal dorѐ.

Jack’s Hut Underground Drilling - JORC Code Table 1 Section 1 Sampling Techniques and Data Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. Diamond Drilling Sample Collection • A diamond core drill rig was used to produce rock samples of core. Run length was variable between 3m and 1m depending on the ground conditions and any expected mineralisation. • Triple Tube HQ and NQ barrel set up was utilised to maximize recoveries. • Diamond drill core is orientated where orientation tools provided an outcome that is assessed as reliable. • The geologist selects sample intervals based on logged geology (lithology, alteration, mineralisation, structures) with minimum sample length of 0.3m and maximum of 1.5m. Half core samples were taken from start to end of hole. All drill core is sampled using an automated/mechanical core cutting machine with diamond cutting blade. Samples comprise half core with sample intervals determined by the geologist and recorded as a cut sheet. • For orientated drill core a cutting reference line is drawn approximately 15mm offset from the orientation line. Drill core is cut along the cut line with the orientation line not sampled and returned to the core box for future reference. • Non-orientated drill core is cut along a reference line that is the best approximation of the extensions of the orientation reference line with the intent of ensuring the same half core is sampled. • Samples are placed in calico bags and dispatched to ALS laboratory where they are received and registered with a sample receipt document provided as a record of the chain of custody process. Analysis of Geotechnical Samples • Field point load testing (PLT) was conducted on solid pieces of core >100mm in length from every 3rd core tray. Different rock type samples were selected to collect a range of data reflecting varying rock mass strengths throughout each hole. Drilling techniques • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). • This release refers to 8 diamond drill holes that have been completed in the program for a total of 1686.5 metres. • The holes were collared in a stockpile off the Jack’s Hut decline. • All holes were diamond cored with HQ3 with the option to reduce to NQ3 where adverse ground conditions were encountered. • All holes were oriented using an Axis North-seeking Gyroscopic tool. During drilling a collar check survey and a 15m survey was taken, followed by surveys every 30m from 30m depth to end of hole. Prior to completing each hole, a multi-shot continuous gyro survey was taken. Each single shot and EOH multi-shot was then uploaded to the cloud-hosted Axis database KINGSTONRESOURCES.COM.AU | ASX: KSN 15 Criteria JORC Code explanation Commentary for retrieval and review by Geology. • Reverse Circulation Drilling • No Reverse Circulation drilling was completed as part of the program being reported or depicted in the release. Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. • Diamond Drill Core • Diamond drill core is recovered on a run-by-run basis where the length drilled, and axial length recovered is recorded by the drilling crew. Run length and recovery are remeasured and calculated in the core processing area. No significant discrepancies have been noted between driller and KSN determined runs and recovery. • Diamond drill core is sampled as half core using a diamond blade auto saw. • Core loss zones have not been sampled. These ‘gaps’ in sampling have been assigned zero (0) grade for the purposes of significant interval calculation. • Reverse Circulation Drilling • No Reverse Circulation drilling referred to or reported or depicted in the release. Logging • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. • A qualified geologist logs all drill core from this program. • Logging captured, lithological, alteration, mineralisation, structural and weathering information. Drill core also provided geotechnical data based on physical counts of and physical measurement of angles, hardness, roughness, of discontinuities and visual assessment and description of structural features. • Geological logging is generally qualitative in nature noting the presence of various geological features and their intensities using a numerical 1-5 scale. Quantitative features of the logging include structural alpha and beta measurements captured as well as magnetic susceptibility and bulk density data. • Bulk density intervals were chosen to represent the range of lithology/alteration and mineralisation within the hole. The test can only be completed on competent core, so areas of broken or clayey core are not represented in the bulk density measurements, • “Dry weight” and “Wet weight” measurements were taken every 3 trays for pieces of core >= 10cm and bulk density calculated using the Archimedes Principal: • Bulk Density = (Sample Weight in Air) *(Fluid Density) / (Sample Weight in Air) – Sample Weight in Water). • The entire set of holes are fully logged and photographed. • Diamond Core Drilling • Recoveries were measured by the driller and/or offsider whilst in the splits on the rack at the rig site using a handheld tape measure. Recoveries were written in permanent marker on a core block placed in the core tray. The Geologist and/or field assistant measured the length of recovered core in the trays when meter marking the core. Recovery is recorded as a percentage per run. • Drill core recoveries across the drill holes average >95% with 95-100% recovery in mineralised zones. • There is no observed relationship between sample recovery and grade.
