Announcement PDF ASX/Media Announcement 15 February 2024 Drilling confirms New Discovery at Mineral Hill • New drill hole hits high-grade mineralisation, mirroring recent discovery in the Southern Ore Zone footwall, and confirming continuity of the mineralised structure. • Significant intersections from drill hole KSNDDH019 include: • • • 21m @ 1.49% CuEq from 254m, including o 2m @ 6.37% CuEq from 255m o 1m @ 2.51% CuEq from 262m o 1m @ 2.52% CuEq from 270m • 4m @ 1.13% CuEq from 383m, including o 2m @ 1.86% CuEq from 385m Discovery less than 200m from existing underground development, opening the door for rapid resource expansion and mine life extension. Strong potential to extend Mineral Resources into these areas and extend the life of mine. Kingston Resources Limited (ASX: KSN) (Kingston or the Company) is pleased to announce that a second drill hole (KSNDDH019) has intersected the newly discovered structure at the Southern Ore Zone (SOZ). This confirms the presence of mineralisation in this region and strengthens the potential for expanding Mineral Resources into this area. On 1 November 2024, Kingston announced a near-mine discovery in drillhole KSNDDH017, which returned a high-grade intersection within a new lode of 12m @ 3.41% CuEq from 405m. There are two main zones of mineralisation in follow-up hole KSNDDH019: a shallower high-grade zone representing mineralisation within the current Mineral Resource estimate, and a deeper intersection representing the up-dip and along strike extension of the original discovery intersection. Kingston now has two pierce points on the structure, providing the Geology team with increased confidence of the potential for expanding our underground Mineral Resource. Follow up drilling of this zone will be completed from the existing underground development. Kingston Resources Managing Director, Andrew Corbett, said: “We are excited to announce the exceptional results of this follow-up drilling. Mineral Hill has an extensive mineral system, and we have been eagerly working to showcase the vast exploration potential within the mine and nearby expansion opportunities. This achievement marks a significant milestone for Kingston, as it paves the way for further discoveries within the mine.” ASX: KSN Shares on Issue: 498M Market Cap: A$39.8M Cash: A$10.5M (31 December 2023) 202/201 Miller Street, North Sydney, NSW 2060 +61 2 8021 7492 info@kingstonresources.com.au www.kingstonresources.com.au @KSNResources Figure 1: KSNDDH019 (200mN cross-section, +-50m window). * High grade domain shapes are sliced on section and drill holes are projected +/-50m.

This latest drill hole not only provides greater confidence in the continuity of this structure, but it also expands the near mine potential along strike and down dip of SOZ. These intercepts allow us to build our knowledge on the controls on mineralisation at SOZ and broader tenure at Mineral Hill, allowing us to update our deposit-scale geological models across the mineral field and region”.

Proportions are based on KSN forward looking USD$ commodity pricing and are not inclusive of metallurgical recovery. CuEqIS%= (Au_ppm*0.63)+ (Ag_ppm*0.0078)+ (Cu%*1.0)+ (Pb%*0.224)+ (Zn%*0.342) **** Assays and mineralised intercepts for KSNDDH017 are considered as final. Drill hole KSNDDH019 was drilled to test up-dip and along strike extension potential of the new mineralised zone intersected at 405m depth downhole in KSNDDH017. The style of mineralisation intersected by both holes is consistent with the known mineralisation within the SOZ. Mineralised shoot and lode geometry at the SOZ broadly changes from a flatter orientation near surface, to a steeper dip at depth. The intercept at 385-387mdh in KSNDDH019 confirms the interpretation that this mineralised structure is dipping approximately 70° to the south-west. Intersecting mineralisation ‘on target’ is encouraging with respect to down dip and along strike potential of this new zone. Further delineation of this lodes is best achieved with flatter inclined underground originating drilling from the existing underground access. Next Steps Kingston is incorporating all new and recent drill hole data into an updated geological interpretation as the basis for constructing geological domains as input to a Mineral Resource Estimate update in H2 FY24. www.kingstonresources.com.au 4 Metal Equivalents This announcement quotes metal equivalent grades for significant mineralised intercepts. The process of selecting significant intercepts involves a first pass of calculating In-Situ Copper Equivalent (CuEqIS) by applying factors based on relative metal pricing. The first pass does not include metallurgical recovery. Drill hole intervals are reported as continuous zones at CuEqIS cut off grade of greater than 0.5% and 1.0%, with 2 metres maximum internal waste and minimum interval of 0.3mdh. Price assumptions used are based primarily on consensus forecasts with adjustments based on company expectations. Upon deriving the significant intercepts with CuEqIS, metallurgical recovery is applied to derive copper equivalent (CuEq) factors for reporting. These 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. CuEq (%) = (Cu x 0.810) + (Au x 0.480) + (Ag x 0.005) + (Pb x 0.178) + (Zn 0.205) 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 CIL circuit and is currently reinstating the flotation circuit to produce gold, copper, lead and zinc concentrates as well as gold/silver dore.

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 underway 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.

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. 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 PQ and HQ barrel set up was utilised to maximize recoveries. PQ was used in weathered zone, typically approximately the first 30m followed by HQ3. • Diamond drill core is orientated where orientation tools provided an outcome that is assessed as reliable. • The geologist selects sample intervals based on logged lithology, alteration, mineralisation and structures with a minimum sample length of 0.3m and a maximum of 1.0m. Drill core is sampled only within potentially mineralised zones and extending up to 10m outside of mineralised zones as determined by visual and/or pXRF analysis. • All drill core is sampled using an automated/mechanical core cutting machine with diamond cutting blade. Samples comprise half core for HQ3, and quarter core for PQ3 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 SGS 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 • Multiple whole core samples were collected and dispatched for laboratory based geotechnical and material properties testing and analysis. • Sample intervals were a maximum 0.5m length along the core axis. • Samples were returned to the core yard where tested/destructed samples were submitted in their entirety for crushing and splitting to ensure a representative sample for geochemical analysis. • Partially destructed samples that can be pieced back together, and non-tested samples were cut using the auto core saw and half submitted for analysis in a manner consistent with drill core sampling procedures. 8 Criteria JORC Code explanation Commentary 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). 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 Core Drilling: - 2 Diamond drill holes (KSNDDH018 & KSNDDH019) were completed in the program being reported for a total of 640.3 m of drill hole. • KSNDDH018 was terminated at 195.5m due to extremely poor ground conditions in the unmineralised cover sequence causing the hole to collapse and fail. • KSNDDH019 was located immediately adjacent to KSNDDH018 with rotary mud open hole to 80.3m, then cased off and the drill hole advanced in PQ3 to 225.8m and further reduced to HQ3 to EOH at 444.8m • To increase probability of completion to target depth, drill holes are completed in triple tube diamond core, PQ3 collar followed by HQ3 tail. In areas where ground conditions created a risk of not reaching target depths in HQ3, the core size was reduced to NQ3. • Where possible core was oriented using a Reflex down hole digital orientation tool. • Historical drill holes through the Talingaboolba Fm. Cover sequence utilised either rotary mud, PQ3 core to a competent formation before reduction to either HQ3 or NQ3 diamond core. • 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 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. • Reverse Circulation Drilling • No Reverse Circulation drilling referred to or reported or depicted in the release. • A qualified geologist and engineering geologist logs all drill core from this program. Historical and KSN DDH and RC holes were logged by a qualified geologist. • 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 data. Logging www.kingstonresources.com.au 9 Criteria JORC Code explanation Commentary 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 for all subsampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. • The entire DDH are logged and photographed. • Diamond Core Drilling • PQ diameter core was used in more broken ground close to surface in order to maximize recoveries. Additionally, the driller adjusted the length of runs depending on ground conditions, shorter runs were used in intervals of more challenging ground conditions. The driller used variable penetration rates to maximize recoverable core. • 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 5-100% recovery in mineralised zones. • There is no observed relationship between sample recovery and grade. • • Diamond drill core sampling intervals are determined by the logging geologist and is defined by key geological characteristics such as lithology, alteration, mineralisation style paragenesis etc, and structure. • Drill core is sampled as half core using an automated diamond blade core saw. • Core is sampled from the same half with a cut at approximately 15mm offset from the BOH orientation line that is retained in the core tray for future reference. • Primary sample intervals are note subsampled further. • Routine QAQC was used in the sampling process. Blank material was introduced at 1:20. Certified Reference Material was introduced at a ratio of 1:20 and in areas of identified mineralization. • Samples from the field are dispatched to the sample preparation facility in Orange where they are dried, crushed and pulverised with a 150g pulp subsample collected for analysis. • Sample representivity and quality is assessed using KSN QAQC protocols. • Half core samples are appropriate for the host rock characteristics and mineralisation style. Mineralised veins are on the whole at moderate angles to core axis enabling a representative sample to be achieved through the half core sampling process. Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make www.kingstonresources.com.au • Geochemical analysis is carried out on all samples using a standardised analytical suite and sample preparation protocol. • Gold analysis is determined by fire assay (FA) by using lead collection technique with a 50g sample charge weight and AAS instrument finish. Gold by Fire Assay (FA) is considered a “complete or total” method for total recovery of gold in sample. • A multi (42) element suit was used for full geochemical coverage.

The 4 Acid digest is a total method. Historically Aqua Regia has been used at Mineral Hill. Kingston has decided to use the more robust 4 acid digest for its drilling programs. The sample 0.2g (df=500) is digested with nitric, hydrochloric, hydrofluoric and perchloric acids to effect as near to total solubility of the sample as possible. With most silicate-based material, solubility is to all intents and purposes complete, however, elements such as Cr, Sn, W, Zr, and in some cases Ba, may prove difficult to bring into solution. This digest is in general unsuited to dissolution of chromite, titaniferous material, barite, cassiterite, and zircon. In sulphide-rich samples, some of the sulphur may be lost (as H2S) or is partially converted to insoluble elemental sulphur. Antimony can also partly be lost as volatiles under this digest. Some minerals may dissolve, or partly dissolve and precipitate the element of interest. Examples are silver, lead in the presence of sulphur/sulphate, barium in the presence of sulphur/sulphate, Sn, Zr, Ta, Nb through hydrolysis. GE_ICP40Q20 has lower upper and lower detection limits with ore grade intercepts often exceeding these limits. Over range Cu-Pb-Zn analysis are reassayed using SGS method GE_ICP41Q20 with higher lower and upper detection limits. KSN utilises a standardised QAQC protocol in the form of standards, blanks and duplicates in the diamond drilling program at all prospects and deposits at Mineral Hill. If a 3SD exceedance of Au or Base Metal (Ag, Cu, Pb, Zn) sample was detected, the laboratory was contacted to re-assay the CRM and adjacent samples. There were no QAQC fails in the Pearse North data set.. Internal laboratory QAQC is analysed and reviewed in addition to the Company QAQC. Significant intercepts for base metal (Cu-Pb_Zn) dominant deposits and mineralisation styles is based on In situ Cu equivalent (CuEq) at 0.5%, 1.0%, & 2.5% cut off grades. Both InSitu and Recovered CuEq are calculated using manual (excel) and automated (Micromine) routines. Significant intercepts are calculated using length weighted average grade calculations for all elements reported. Significant intercepts are checked and verified with reference to the drill hole logging data sets and visual checks of the remnant half core in the core tray. In situ CuEq% does not consider recovery and payability for precious and base metals or penalties for potential penalty elements. • CuEqIS% (InSitu) is calculated based on the following economic parameters and formula: • CuEqIS%= (Au_ppm*0.61)+(Ag_ppm*
