Announcement PDF 1 of 18 01 OCTOBER 2026 HIGH-GRADE INTERSECTIONS EXTEND NUGENT MINERALISATION Kantra Copper Limited (Kantra or Company) (ASX:KAN) is pleased to provide an update on the drilling activities at the Kanmantoo Copper Mine in South Australia. High grade Copper-Gold (Cu-Au) mineralisation continues to be intersected in underground drilling at Nugent, including: • 70m @ 1.18% Cu + 0.24g/t Au from 507m downhole in 26KVUG0949, including1 ; o 38m @ 1.46% Cu + 0.18g/t Au from 507m downhole o 9m @ 0.67% Cu + 0.21g/t Au from 546m downhole o 21m @ 0.96% Cu + 0.37g/t Au from 556m downhole • 13m @ 0.92% Cu + 0.06g/t Au from 376m downhole in 26KVUG0950 • 7.2m @ 1.12% Cu + 0.09g/t Au from 589.8m downhole in 26KVUG0948 • 7m @ 1.74% Cu + 0.02g/t Au from 530m downhole in 26KVUG0947 • 4.8m @ 1.3% Cu + 0.21g/t Au from 104.2m downhole in 25KVUG0819 • 8.44m @ 0.83% Cu + 0.95g/t Au from 237m downhole in 25KVUG0632 Figure 1: View towards the North showing key Copper grades intersected in Nugent in relation to the 2025 Mineral Resource Estimate (MRE) 1 Due to drill angle not true width 2 of 18 Commenting on the drilling results, Kantra CEO and Managing Director, Bob Fulker said: “These results continue to demonstrate the growth potential of the Nugent lode, with drilling confirming mineralisation well below the current mining horizon and highlighting opportunities to further expand resources at depth.” Figure 2: Plan view showing key Copper grades intersected Nugent Geological Context, and Recent Drilling The Nugent lode is positioned on the south-west edge of the Kanmantoo deposit, and is characterised by a single, structurally controlled mineralised corridor containing discrete mineralised pods along its strike extent. Nugent is distinguished by generally higher gold grades relative to other areas of the Kanmantoo deposit. Deep diamond drill fans collared from the 910 Backfill Stockpile targeted extensions of the Nugent lode below the 2025 MRE drilling between 600m RL and 480m RL. This drilling has confirmed the continuity of the Nugent system, 70m below the 2025 Mineral Resource Estimate (MRE) and 370m below the current stoping horizon at the 950 Level. Upper drill fans collared from the 950 and 920 Diamond Drill Cuddies (DDCs) were designed to test the northern extent of the early stoping panels, and have provided evidence of geological continuity and improved understanding of localised geometries. The recent drilling was designed to collect both geotechnical and geological information. Geological logging has refined the interpretation of a significant brittle joint zone at the north-eastern extent of the Nugent system, associated with the contact between contrasting lithological units. This work has further defined the structural 3 of 18 complexity of the Nugent lode and provided important geotechnical information to support future stope design and mine planning. Mineralisation widths have varied in comparison to the 2025 MRE as the increased data density has provided better clarity on the individual mineralised pods. The Saddle Zone was also intersected within holes 26KVUG0950, 26KVUG0949 and 26KVUG0958 while drilling to target Nugent. A change in the behaviour of the Nugent structure was also identified within the deep drill fan at approximately 640m RL. The observed geometry is interpreted to represent a possible second mineralised lens sub-parallel to the main Nugent structure. This interpretation is supported by drillhole 26KVUG0949, which intersected 70m at 1.18% Cu and 0.24g/t Au from 507m downhole. Further drilling is planned to test this interpretation and improve the understanding of the structural architecture of the system at depth. 2026 underground diamond drilling completed to the end of August totals 38,535m, including 12,024m of Nugent drilling across both grade control and resource definition programs. Assay results received by the 3rd of August have been incorporated into the 2026 MRE update. Results from 26KVUG0958 and 26KVUG0959 were received after the MRE cut-off date and have not been included. The 2026 MRE is expected to incorporate approximately 80,000m of drilling inclusive of drilling completed during H2 2025, and is scheduled for release in late October.

APPENDIX B – JORC TABLE 1 Section 1 Sampling Techniques and Data Criteria Commentary Sampling techniques • The Diamond Drill Hole (DDH) sampling was conducted as per the Kantra procedures and QAQC protocols. • Sample intervals from 1.2m 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. • 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, structure, weathering and mineralisation by Kantra geologists in accordance with Kantra’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 KANTRA 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 Kantra 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 97% illustrating competent ground conditions. UG drill core is selectively oriented. Where required, orientation of structure relative to the dominant S2 foliation is recorded. Sub-sampling techniques and • 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 Kantra. From the 200 gram sub-split a 2 gram aliquot was scooped and weighed by ALS for 4-acid digestion. 14 of 18 Criteria Commentary sample preparation • Kantra 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. Quality of assay data and laboratory tests • 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 KANTRA 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. Results from all returned QAQC samples provide reasonable confidence as to the accuracy of the assay results used in the estimation. 100% of assays fall within 2SD of the expected CRM mean grade for Cu and 92% of assays fall within 2SD for Au. All anomalous Au standards were checked and attributed to a 15 of 18 Criteria Commentary poor standard following the return of all surrounding samples aligning with originally assay values. o Laboratory inserted QAQC samples were inserted with a minimum of two standards and one blank for every batch of 40 samples. • Quartz flushes with <60ppm Cu are introduced to the crushers and bowl pulverisers within every high sulphide interval. 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. • Kantra‘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 Kantra 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. Location of data points • The map projection of Map Grid of Australia 1994 - Zone 54, (MGA94-54) is used for all work undertaken for this drilling. • Height is reported in Mine Relative Level (RL) which is ASL +1000m • The UG rigs set ups are aligned by qualified surveyors setting up the drill rigs in the UG drill access. • All drill hole collars are set out with a Leica survey total station. The accuracy of this instrument is 0.01m. All location information is reported in MGA94-54 coordinate system. When drilling is completed from this pivot point the hole reported will have the collar point adjusted via pick up with the total station. • Downhole surveys were determined using a gyro survey instrument at 30m 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 • All holes are angled drill holes, dipping between -21 to -57 deg. Drill holes are orientated towards the South East from 105deg to 175deg (MGA Grid North). • All down hole surveys are by Reflex or Axis Gyro. • Dominant mineralisation trends as measured from in-pit and Underground mapping are strike between 020-040deg and dip -75deg to east. 16 of 18 Criteria Commentary geological structure • 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 Kantra employee is responsible for collecting and organising the samples ready for assay. Kantra has a detailed sample collection/submission procedure in place to ensure sample security. • Drill core is transported from the UG drill site to Kantra’s core yard at Kanmantoo under the supervision of Kantra staff. • Transport of the 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 Kantra 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.
