High Grade KINGSTONRESOURCES.COM.AU | ASX: KSN 3 Managing Director and CEO, Andrew Corbett commented: “KSNDDH105 is an excellent high-grade copper-gold intersection and the standout result from this drilling. More broadly, the drilling intersected the D, G and H Lodes in their interpreted positions across northern SOZ, supporting our geological model and the potential for further Mineral Resource growth. “Mineralisation remains open to the north, with assays pending from further step-out holes. These results will be incorporated into the SOZ Mineral Resource update targeted for the March quarter of 2027, which will then inform subsequent mine planning and Ore Reserve conversion work.” Figure 1: Plan view of the recent northern extension drilling targeting D, G and H Lodes These drill holes mark the first completed program for the FY27 period and were designed to test the northern boundaries of the D, G and H Lode mineralisation at SOZ. The holes have successfully intersected the interpreted position of the main lodes and the mineralisation remains open to the north. Additionally, very high-grade mineralisation has been intersected in deeper hanging wall lodes, with KSNDDH105 returning 3.00m @ 4.73% Cu, 6.08g/t Au, 16g/t Ag (11.92% CuEq) from 119m, including 1.00m @ 8.71% Cu, 9.90g/t Au, 30g/t Ag and 1.00m @ 3.88% Cu, 8.14g/t Au, 15g/t Ag.

KINGSTONRESOURCES.COM.AU | ASX: KSN 9 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 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.

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 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 KINGSTONRESOURCES.COM.AU | ASX: KSN 17 Criteria JORC Code explanation Commentary 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 11 diamond drill holes for a total of 2,399.8 metres. • The holes were collared in a drill drive just off the main SOZ access drive. Plans and cross-sections are included in the body of this announcement. • 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. • 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 • 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 KINGSTONRESOURCES.COM.AU | ASX: KSN 18
