Announcement PDF ASX/Media Announcement KINGSTONRESOURCES.COM.AU 202/201 Miller Street, North Sydney, NSW 2060 +61 2 8021 7492 info@kingstonresources.com.au Follow us on X (Twitter) @KSNResources Drilling Extend Upper High-Grade Zone at SOZ, Mineral Hill Kingston Resources Limited (ASX: KSN) (‘Kingston’ or ‘The Company’) has extended the high-grade upper A Lode at the Southern Ore Zone (SOZ), Mineral Hill, with new assay results confirming continuity of mineralisation to the east and south, remaining open in both directions. This is significant because A Lode underpins a large portion of the current Mineral Resource at SOZ — an extension to the east and south increases the potential for additional tonnage in planned Mineral Resource updates. Key Highlights: KSNDDH085 77.10m @ 0.62g/t Au, 0.66% Cu, 4.07% Pb, 2.49% Zn, 53g/t Ag from 154.0m (20m true width or TW), including: • 31.10m @ 2.68% Pb, 2.62% Zn, 24g/t Ag from 165.9m (10m TW) • 22.10m @ 1.62g/t Au, 1.47% Cu, 8.98% Pb, 3.13% Zn, 132g/t Ag from 209.0m (~9m TW) KSNDDH086 7.70m @ 2.39% Cu, 3.37% Pb, 0.26% Zn, 55g/t Ag from 45.0m 7.00m @ 1.43g/t Au, 2.15% Cu, 26g/t Ag from 97.5m KSNDDH079 8.00m @ 2.27g/t Au, 1.50% Cu, 11g/t Ag from 54.0m KSNDDH069 2.35m @ 4.43g/t Au & 1.33% Cu, from 20.3m 4.40m @ 1.09g/t Au & 1.44% Cu, from 72.2m 3.05m @ 4.68g/t Au & 1.28% Cu from 86m KSNDDH068 6.20m @ 0.93g/t Au & 0.92% Cu from 71.2m 10.85m @ 0.39g/t Au & 1.03% Cu from 80.1m Notes on true width: all holes, except for KSNDDH085, are drilled approximately perpendicular to the lode dip plane. 9 July 2026 KINGSTONRESOURCES.COM.AU | ASX: KSN 2 Managing Director and CEO, Andrew Corbett commented: “The Upper A Lode, intersected with KSNDDH085, is one of the highest-grade parts of the Southern Ore Zone. Our geology team is keenly aware of the potential to grow the estimated tonnage here. We’ve got 25,000m of drilling planned for FY27 and a key part of this will be obtaining approvals for surface drilling to target discoveries and extensions adjacent to the existing underground development. These results reinforce our confidence in the scale of the SOZ system and support our pathway to a larger, longer- life underground operation at Mineral Hill.” These results extend the Southern Ore Zone on two fronts. To the east and south, the high-grade, polymetallic Upper A Lode continues to grow and remains open. At the northern end of SOZ, KSNDDH079 has extended the Au-Cu rich G/H Lode further to the north, while KSNDDH068 and KSNDDH069 have infilled and confirmed high- grade mineralisation within the existing model.

Interval highlighted in pink; 3.4m @ 1.09g/t Au, 2.82% Cu, 6.86% Pb, 1.86% Zn, 77g/t Ag from 38.6m . KINGSTONRESOURCES.COM.AU | ASX: KSN 4 KSNDDH085 was designed to infill the upper sections of the A Lode mineralisation at the Southern Ore Zone (SOZ). Immediately north of this drill hole, the mineralisation is interpreted to dip approximately 17° to the west. This drill hole has now extended the extremely high-grade mineralisation in this lode to the south and remains open. This reduces geological risk in areas already included in the Mineral Resource, while the southward extension opens up new mineralised strike length beyond the current resource boundary. The high-grade intersection between 209m and 231.1m has returned high-grade assays for gold, copper, lead, zinc and silver, but is particularly high for lead and zinc. The sections of solid galena (lead mineral) are shown in the core photos in Figure 3 between 223.45 and 228.75m. The highlight intersections for KSNDDH085 include: • 31.10m @ 2.68% Pb, 2.62% Zn, 24g/t Ag from 165.9m (KSNDDH085). • 22.10m @ 1.62g/t Au, 1.47% Cu, 8.98% Pb, 3.13% Zn, 132g/t Ag from 209.0m (4.25m true width) (KSNDDH085). KSNDDH086 was drilled to beneath hole 085, also returning excellent results, confirming the existing Mineral Resource geological model.

KINGSTONRESOURCES.COM.AU | ASX: KSN 6 Figure 4: Strip log of intersection 209m to 231.1m in KSNDDH085. KSNDDH068, 069 and 079 have intersected high-grade copper-gold mineralisation in the G Lode and H Lode areas at the northern end of the Southern Ore Zone. The mineralisation is hosted in quartz-carbonate veins and structures with significant chalcopyrite (copper mineral). Highlight intersections include: • 6.20m @ 0.93g/t Au & 0.92% Cu from 71.2m (KSNDDH068) • 10.85m @ 0.39g/t Au & 1.03% Cu from 80.1m (KSNDDH068) • 2.35m @ 4.43g/t Au & 1.33% Cu, from 20.3m (KSNDDH069) • 4.40m @ 1.09g/t Au & 1.44% Cu, from 72.2m (KSNDDH069) • 8.00m @ 2.27g/t Au, 1.50% Cu, 11g/t Ag from 54.0m (KSNDDH079) Drilling is continuing in the Southern Ore Zone, currently targeting potential extension zones in the G and H Lode area.

Figure 6: Oblique cross section - KSNDDH068 and KSNDDH089. KINGSTONRESOURCES.COM.AU | ASX: KSN 8 Metal Equivalents This announcement quotes metal equivalent grades as defined by Kingston Resources. 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 is currently producing metal concentrates and dorѐ (from the CIL circuit) on site. With polymetallic underground production, the mine's revenue base will broaden across gold, copper, lead, zinc and silver, supporting more stable cash flow through commodity price cycles. 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 dorѐ.

SOZ Underground Drilling - JORC Code Table 1 Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.) 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 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 KINGSTONRESOURCES.COM.AU | ASX: KSN 17 Criteria JORC Code explanation Commentary 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. 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). • Diamond Core Drilling: - 36 diamond drill holes have been completed to date for a total of 4042.6 metres • This release refers to 5 diamond drill holes that have been completed in the program for a total of 844.9 metres. • The holes were collared in two separate sites in existing SOZ underground drives on the 1100 Level. • 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 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. • 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 KINGSTONRESOURCES.COM.AU | ASX: KSN 18 Criteria JORC Code explanation Commentary • 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. 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, KINGSTONRESOURCES.COM.AU | ASX: KSN 19 Criteria JORC Code explanation Commentary • “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. Sub- sampling techniques and sample preparation • If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted • Diamond drill core sampling intervals are determined by the logging geologist and is defined by key geological characteristics such as lithol
