Announcement PDF ASX/Media Announcement 3 June 2025 Underground drilling intersects high grade gold and copper Exceptional high-grade gold and copper intercepts confirm growth potential at Mineral Hill’s Southern Ore Zone Highlights: • Outstanding high-grade intercepts returned from first underground drilling at Southern Ore Zone (SOZ), including ounce-per-tonne gold assays. • Significant extensions of mineralisation 50-100m along strike beyond current resource envelope suggest strong potential to increase Mineral Resource tonnage. • High grade intersected in KSNDDH032 (8.8m @ 42.51g/t Au, 1.77% Cu [1.0% CuEq COG]), directly within a planned stope zone. • • Other key intercepts include (0.5% CuEq COG): o 12.15m @ 30.80g/t Au, 1.39% Cu from 58.65m (KSNDDH032) o 8.1m @ 3.69g/t Au, 0.85% Cu from 65.9m (KSNDDH026) o 2m @ 8.57g/t Au, 0.25% Cu from 149.7m (KSNDDH026) o 9.3m @ 2.13% Cu from 43.7m (KSNDDH027) o 5.6m @ 1.82g/t Au, 1.84% Cu from 74m (KSNDDH029) o 2m @ 1.78g/t Au, 13g/t Ag, 4.40% Cu from 70m (KSNDDH035) Results reinforce the high-grade, high-margin potential of SOZ and provide optionality to extend the underground mine plan and improve economic returns. Kingston Resources Limited (ASX: KSN) (‘Kingston’ or ‘The Company’) is pleased to announce the results of the first 13 drill holes from underground drilling at the Southern Ore Zone. Drilling commenced in February 2025 (see ASX announcement on 26 February 2025) and numerous holes are currently being assayed. Drill holes were designed to infill planned stopes for the first 12 months of underground production. Results clearly demonstrate the high grade, high margin nature of the ore at Mineral Hill. KSNDDH032 has intersected outstanding gold and copper grades, with the highest grade being an 8.8m interval grading 42.5g/t gold and 1.77% copper from 62m down hole. Additionally, drillholes KSNDDH024 to KSNDDH026 have extended mineralisation 50-100m north of the current Mineral Resource extents. These holes were targeting the deep A-lode position of the deposit and have intersected mineralisation along the way. The results indicate a potential for material expansion to Mineral Resource tonnage in this area.

It has been a long time since the Southern Ore Zone was drilled from underground and this campaign is showing the untapped potential waiting to be uncovered. What’s particularly exciting is the clear potential to grow our Mineral Resource. Drilling has already extended mineralisation up to 100 metres beyond the current resource boundary, opening the door to a potential uplift in tonnage and mine life. With underground development already in place to access some of these high-grade zones, we’re well positioned to convert these results into early cash flow. These outcomes strengthen our confidence in Mineral Hill as a long-life, high-margin operation and we look forward to unlocking further value as we continue drilling throughout 2025.” Resource Definition Drilling The current underground drilling campaign is being collared at drill drives and off the decline to infill the copper-gold dominant lodes on the western side and the lead-zinc-silver lodes on the eastern side. Twentyone (21) drill holes are complete with final assays received for 13. Results pending (8 holes) are due by the end of Q4. KSNDDH032 has intersected extremely high-grade gold mineralisation in the expected position of a planned stope. Results include 8.8m @ 42.51g/t Au, 1.77% Cu from 62m down hole. Underground development is already in-place to access this lode. MRE Measured MRE Indicated MRE Inferred Assays Received Drilled Hole Planned Hole Figure 1: Long section of the SOZ drillholes looking east. KSNDDH024 to KSNDDH026 were drilled to target the polymetallic A Lode. Prior to reaching the intended target, additional mineralisation was intersected in hole 024 and 025. This zone has previously lacked any substantial drilling information, meaning Mineral Resource interpretations were not extended into this area. The Company will now look at adding more holes here and target an extension to the Mineral Resources up to 100m beyond the current northern extents. 2 www.kingstonresources.com.au Figure 2: Plan view of SOZ drill holes with assay results so far. On Completion of the sale of the Misima Gold Project we intend to ramp up exploration at Mineral Hill. This current drill campaign was initially budgeted to be 3000m of drilling, however it now will be extended to firm up additional production areas and target areas with potential extension to the Mineral Resources.

Price assumptions used are based primarily on consensus forecasts with adjustments based on company expectations. Copper equivalent insitu (CuEqIS) 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). Copper equivalent recovered (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. Metallurgical recoveries are based on historical production (2010-2016) as well as recent metallurgical test work and are applied to the 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 dore.

Criteria JORC Code explanation Sampling techniques • Nature and quality of sampling (eg 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. Drilling techniques • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). www.kingstonresources.com.au Commentary 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 refence line is drawn approximately 15mm offset form 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. • Diamond Core Drilling: - 21 diamond drill holes have been completed to date for a total of 3010 metres • This release refers to 13 diamond drill holes that have been completed in the program for a total of 1332.3 m. • 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 11 Criteria Drill sample recovery Logging JORC Code explanation Commentary • 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. 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. • 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. • Whether core and chip samples have been geologically and geo
