Announcement PDF 22 May 2025 MULTIPLE NEW HIGH GRADE COPPER GOLD DRILLING RESULTS EXTEND MINERALISATION AT NUGENT BEYOND THE RESOURCE  Ongoing underground diamond drilling at Nugent continues to demonstrate strong depth extension of the copper-gold mineralisation, which is now down to 380 metres below the historic open pit and remains open down plunge  Drilling returned multiple outstanding results, including: 8.4m @ 1.3% Cu & 0.23g/t Au (uncut) from 207.2m downhole in 25KVUG0533 26m @ 1.21% Cu & 0.27g/t Au (uncut) from 299m downhole in 25KVUG0534 ▪ 16m @ 1.19% Cu + 0.23g/t Au (uncut) from 200m downhole in 25KVUG0528 ▪ 17m @ 1.11% Cu + 0.38g/t Au (uncut) from 76m downhole in 25KVUG0538 ▪ 5.2m @ 0.89% Cu + 0.07g/t Au (uncut) from 295.8m downhole in 25KVUG0532  Notably hole 25KVUG0532 is 60 metres below the existing 2024 Mineral Resources Estimate 1 and remains open down plunge, which will continue to be tested with further drilling  As recently announced, Hillgrove is fast tracking the development of Nugent to increase throughput and copper production, with first ore from Nugent targeted to be processed through the mill in the December 2025 Quarter Commenting on the drilling results, Hillgrove CEO and Managing Director, Bob Fulker said: “The results of this extensional drilling program at Nugent are material to the Company as they clearly demonstrate the continuity and depth potential of the Nugent copper-gold mineralisation system. In particular, the deepest of the holes that we drilled to the 700mRL(25KVUG0532), which is 380 metres below the Nugent pit – or 60 metres below the existing 2024 Mineral Resource Estimate and the planned development. These results continue to extend the known depth of the Nugent mineralisation and are pleasingly at grades higher than the global Reserve grade of 0.76%. Results such as these continues to reinforce our confidence in the significant resource growth potential at Nugent and more broadly, Kanmantoo. We are well into the process of accelerating the Nugent development and look forward to bringing this deposit into production later in the year” 1 Refer to ASX release on 18 October 2024 titled Maiden Kanmantoo Underground Ore Reserve And 96% Increase In Copper Mineral Resource Endowment Hillgrove Resources Limited ACN 004 297 116 Ground Floor, 5-7 King William Road, Unley SA 5061, Australia | T + 61 8 7070 1698 | E info@hillgroveresources.com.au Figure 1: Nugent towards the NW showing new and key previously reported drilling intersections 2+ 3 Hillgrove Resources Limited (‘Hillgrove’, ‘the Company’) (ASX:HGO) is pleased to provide the following drilling update at its Kanmantoo Copper Mine located at Kanmantoo, 55 kilometres southeast of Adelaide in South Australia. Hole 25KVUG0532 extends the Nugent mineralisation to the 700m RL. This represents the new deepest Nugent intersection 80m below the results released in ASX release on 24 March 2025 titled New High-Grade Copper-Gold Intersections Extend Mineralisation at Nugent which included drilling results to 820mRL. The drilling of the Nugent lode has continued to identify the lode geometry by targeting the lode extremities, identifying the lode plunge and internal geometries resulting in drill holes with no significant intersection returned. Current results are consistent with the hypothesis that the Nugent Mineralisation occurs as pods along the Nugent structural corridor. Hole 25KVUG0533 was stopped earlier than design as a result of the ground water flow rate which impacted drilling conditions.

Figure 2 below shows a plan view of the key drilling results in relation to the planned Nugent Level Development. Drilling is ongoing for both stope definition and Resource expansion drilling along the Nugent copper-gold mineralisation system with the information continuing to provide input into future planning alongside operational requirements for stope and development designs. Drilling from underground is on track to achieve the target of 60,000m including 19,000m of exploration target drilling with 5,045m of diamond drilling completed in April, following the commencement of the third drill rig mid month. Since the previous Mineral Resource Estimate was completed approximately 35,000m has been completed to the end of April. An updated resource estimation will be release in Q4 2025 following a mid year data close off window. Figure 2: Plan view of Significant Nugent holes 56 in relation to planned Nugent development.

Sample intervals from 1.0m to 0.30m as determined by geology through visibly mineralised zones were split from the drill core, with the drill core sawn in half with a diamond core saw. Hole 25KVUG0538 was whole core sampled on-site, where the whole interval of drill core is crushed to 75% < 2m by Hillgrove’s Orbis OM100 Crusher before these crushed pulps were sent to ALS for further preparation and analysis Samples were prepared by ALS Adelaide with each sample being wholly pulverised to >85% passing <75µm. Drilling techniques • All UG drilling is undertaken by external drilling contractor, DRC Drilling. All holes drilled with NQ. NQ Core size is 47.6mm in diameter. Drill sample recovery • Recovered drill core metres were measured and compared to length of drill hole advance to calculate core recovery for every core run. On average sample recovery is >98%. There is no correlation between sample recovery and copper grades in this DDH drill program. • When intersecting the fractured rock aquifers sample recovery has been observed to decrease for a discrete zone before returning to standard conditions Logging • All drill core was logged for lithology, alteration, weathering and mineralisation by Hillgrove geologists in accordance with Hillgrove’s Core Logging Procedure. Colour and any additional qualitative comments are also recorded. • High quality photographs of all drill core before being sampled were taken under controlled light at the HGO core yard at Kanmantoo. • All geological logging is recorded into Geobank (a database product from Micromine) templates and visually validated before being imported into the Hillgrove drill hole database. Additional validation is conducted automatically on import. • In addition, a geotechnical log of all drill core is recorded utilising standard geotechnical logging indexes. RQD is 98-100%. UG drill core is not oriented. Where required, orientation of structure relative to the dominant S2 foliation is recorded. Sub-sampling techniques • For selected intervals the core was sawn in half and the half core despatched to ALS for each sample interval and the entire sample then crushed and 1kg riffle split from the crushed mass and the 1kg sub-sample then pulverised. A sub-split of 200 grams was then split by ALS and retained, and the reject pulverised material returned to Hillgrove. From the 200 gram sub-split a 2 gram aliquot Hillgrove Resources Limited ACN 004 297 116 Ground Floor, 5-7 King William Road, Unley SA 5061, Australia | T + 61 8 7070 1698 | E info@hillgroveresources.com.au and sample preparation • • Quality of assay data and laboratory tests was scooped and weighed by ALS for 4-acid digestion. Hole 25KVUG0538 was whole core sampled on-site, where the whole interval of drill core is crushed to 75% < 2m by Hillgrove’s Orbis OM100 Crusher a 1kg riffle split from the crushed mass and the 1kg sub-sample then pulverised. A sub-split of 200 grams was then split by ALS and retained, and the reject pulverised material returned to Hillgrove. From the 200 gram sub-split a 2 gram aliquot was scooped and weighed by ALS for 4-acid digestion. Hillgrove have detailed sampling and QAQC procedures in place to ensure sample collection is carried out to maximise representivity of the samples, to minimise contamination, and to maintain sample numbering integrity. • The samples were submitted to ALS for analysis. ALS code ME-MS61 using a 4-acid digest with determination by Mass Spectrometry. If the copper result was greater than 1%, the analysis was repeated using a modified acid digestion technique. Gold is assayed by 30g Fire Assay. If > 10 g/t then repeated by fire assay with a gravimetric finish. • The QAQC of sample preparation and analysis processes were via the following samples: o Certified reference materials (CRM’s) inserted by HGO into the sample sequence at a frequency of one in 20. OREAS standard 523B has been used to provide a CRM Standard grade of 1.66% Cu, and 1.05 g/t Au and OREAS standard 924 has been used for copper at a CRM standard grade of 0.512% Cu which are relevant for the expected cutoff grades used for resource estimates across the Kanmantoo deposit.

These are monitored and where Cu contamination of the quartz flush occurs the batch is repeated. For the holes reported there are no examples of sulphides contaminating successive samples via sample preparation processes. • Hillgrove‘s quality policy is that at a minimum of 5% of all samples are CRM’s, and 5% of samples submitted are blanks thus ensuring that as a minimum, 10% of all samples submitted for analysis are Hillgrove QAQC samples. Verification of sampling and assaying • Sample data sheets are prepared in Geobank Field Teams and printed for technicians use. All core is marked for sampling and confirmed by the logging geologist. Sample Sheets also include the sample number sequence and the sample numbers to be assigned to the QAQC samples. Sample intervals input from the excel spreadsheet into an SQL database via Geobank. Data was visually checked by the Geologist prior to import and additional validation was carried out by the database upon import. Copper results were reported in ppm units from the laboratories and then converted to a % value within the database.

The accuracy of this instrument is 0.01m. All pick-ups were reported in MGA94-54 coordinate system once the drill rig is moved from the collar pivot point. The hole reported will have the collar point adjusted at the conclusion of drilling from this site. • Downhole surveys were determined using a gyro survey instrument at 12m intervals and recorded in Grid North. Data spacing and distribution • See Table 2 above and Figures 1 and 2 in the body of the text for drill hole locations. Orientation of data in relation to geological structure All holes are angled drill holes, dipping between -55 to +10 deg. Nugent holes are oriented towards the South from 098deg to 177deg (MGA Grid North) • All down hole surveys are by Reflex or Axis Gyro. There is no oriented UG drill core. • Dominant mineralisation trends as measured from in-pit mapping are strike 045deg and dip -75deg to east. • It is important to note that current drill holes are all at various strike and dip angles to section, and that the true width varies for each intersection. Sample security • A Hillgrove employee is responsible for collecting and organising the samples ready for assay. Hillgrove has a detailed sample collection/submission procedure in place to ensure sample security. • Drill core is transported from the UG drill site to Hillgrove’s core yard at Kanmantoo under the supervision of Hillgrove staff. • Transport of the half-sawn drill core samples for ALS assaying is by dedicated road transport to the Adelaide sample preparation facility. All samples are transported in sealed plastic bags and are accompanied by a detailed sample submission form. • At ALS, on receiving a batch of samples, the receiving laboratory checks received samples against a sample dispatch sheet supplied by Hillgrove personnel. On completion of this check a sample reconciliation report is provided for each batch received. Audits or reviews • There has not been an external review of this DDH drilling program. Previous audits of the Hillgrove sampling methods were reviewed by independent consultant and were considered to be of a very high standard. • Hillgrove Resources Limited ACN 004 297 116 Ground Floor, 5-7 King William Road, Unley SA 5061, Australia | T + 61 8 7070 1698 | E info@hillgroveresources.com.au Section 2 Reporting of Exploration Results Criteria Commentary Mineral tenement and land tenure status • The Kanmantoo Cu-Au mine is situated on Mining Lease ML6345 + ML6436 and is owned 100% by Hillgrove Resources Limited (HGO). • HGO owns the land covered by the Mining Lease. The Mine Lease is encompassed on all sides by EL6526 also owned 100% by Hillgrove Resources. All drill holes were drilled on land owned or rented by Hillgrove Resources. Exploration done by other parties • Hillgrove Resources commenced exploration drilling in 2004 and since then has completed a number of exploration sampling and mapping campaigns which have resulted in defining the drill targets. Geology • Mineralisation occurs as an epigenetic system of structurally controlled veins and disseminations of chalcopyrite, pyrrhotite, pyrite, magnetite, within a quartz + biotite + andalusite ± garnet ± chlorite +/- staurolite schist host rock. Structural studies suggest the mineralisation is within brittle structures that have been re-activated. Drill hole Information • Drill collars, surveys, intercepts are reported in the body of this release. Data aggregation methods • Intercepts tabulated in the table are amalgamated over a minimum down hole length of 3m > 0.3% Cu with a maximum of 2m internal dilution < 0.3% Cu. Or a minimum down hole length of 3m > 0.3g/t Au with a maximum of 1m internal dilution < 0.3g/t Au. No assays were cut before amalgamating the intercept Mineralisation widths • Table of downhole mineralised intercepts is reported in the body of this release. Diagrams • Diagrams that are relevant to this release have been included in the body of the release. Balanced reporting • All drill holes have been reported. Other exploration data • Insitu rock density has been measured by wet immersion method. The results indicate that the bulk rock density of 3.1t/m3 as used at the Kavanagh mine site is still a reasonable representation of bulk density for all mineralisation.
