Kingston Resources Limited (“Kingston” or “Company”) (ASX: KSN) is pleased to report updated drilling and assay information from recent resource definition drilling at Mineral Hill’s underground mine, intercepting individual grades as high as 25.03g/t gold, 295g/t silver, 6.45% copper, 29.70% lead and 34.71% zinc. Drilling was designed as infill in areas of potential early production and extension to the northwest.

The mineralisation within the “A Lode” in the Southern Ore Zone (SOZ) is continuous over a 400m strike length, with mineralisation remaining open to the northwest and southeast. This highly successful drilling campaign has not only increased our confidence on the geological continuity, but also identified new zones of mineralisation (“new lode”) in the footwall of SOZ and enhanced our understanding of the controls of the orebody. We’ve already pinpointed additional target areas to expand SOZ with further drilling.” Currently, the Southern Ore Zone (SOZ) underground mineral resource, stands at 3.8 million tonnes. This round of drilling has increased the understanding of and confidence in the controls of the orebody, which will aid in future exploration and resource expansion activities. Drill holes KSNDDH020, 21, 22 and 23 were drilled to infill the upper areas of the underground resources. Mineral Hill has existing underground development in place, allowing for a rapid restart of underground mining. The company released an underground production target in June 2023, which outlined a life of mine out to 2027 (see ASX Announcement on 29 June 2023). Access to the deeper parts of the underground mine has been reestablished and the development has been fully rehabilitated by pumping out water and installing ground support. Follow up drilling on these results will commence later this year from the underground drill platforms. Figure 1: Cross section for drill holes KSNDDH020 and 21. * High grade mineralisation shapes are sliced on section and drill holes are projected +/-20m. This may create apparent discrepancies between mineralised intercepts and domain shapes. ** See Table 3 for the full assay information that constitutes the assay component of CuEq calculation. Metallurgical recoveries and metal pricing used for the CuEq calculation is shown under Metal Equivalents below. www.kingstonresources.com.au 2 MINERALISATION The mineralised intersections are typical of the Mineral Hill polymetallic deposit style. The deposit is characterised by metal zonation with some areas being more copper-gold rich and others being more leadzinc-silver dominant. The intersections in this round of drilling are characterised by intensely altered lodes 540m wide with chalcopyrite, sphalerite and galena rich veining and breccia fill, with multi-generational quartzcarbonate-sulphide veining and breccias. Selected zones are very high in gold concentration, delivering highly elevated metal endowment overall in copper equivalent terms. Orientated drill core measurements confirm interpretations that the A lode mineralised lodes are steep west dipping consistent with the orientation and distribution of the other SOZ lode zones. A-lode breccia zones 540m true width remain open along strike and down dip with current extents informed by drilling as standing at approximately 400m strike length and 200-250m down dip.

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.

Strong Financial Viability: Pre-Tax Net Present Value (NPV) of A$956 Million (based on a US$1,800/oz Gold Price). Gold Price Upside: Highly leveraged to the upside of the gold price, amplifying potential returns. Current Focus: Prioritising ESIA reports, strategic funding & development strategies. 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.
