Dry metric tonnes. 2. Stope cut-off grade 0.8% CuEq (Copper Equivalent) to define development limits, 0.6% CuEq for stopes along defined development. Development cut-off grade 0.4% Copper. Minimum stoping widths of 4m true width. 3. Reported Ore Reserves do not include any diluting Inferred, Unclassified or Sterilised material. The Mine Schedule includes 499kt at 0.35% Cu of non-Reserving material that is mined as unavoidable dilution or is a sterilisation shell around extracted stopes. 4. Reported grades are rounded to two significant figures. Tonnes are rounded to two significant figures. Copper equivalent to one significant figure as for reporting recoveries and payabilities are averaged values and so have a lower accuracy. 5. Any minor apparent discrepancies for sums in the table are due to rounding. 6. The period of economic extraction is from July 2026 to December 2029. 7. Ore Reserves are converted from Mineral Resources based on 2026 Mineral Resources, reported herewith. 8. Competent Person: Huw Wright MAusIMM (#3078867) with technical review by Mark Hamilton FAusIMM (#221080). 9. Over 30 months of mining actual data demonstrates very good ground conditions. It is expected that this will continue, with Geotech modelling demonstrating stability over modelled life of mine. Copper equivalent includes copper and gold. The calculation expresses recovered and payable gold value as an equivalent in-situ copper grade. Driving values are Cu = US$4.20/lb, Au = US$3,250/oz; metallurgical recoveries are Cu Rec = 95.8%, Au Rec = 54.9%; and payabilities are Cu Pay 95%, Au Pay 90%. CuEq (%) = Cu (%) + 100 × [(Au (g/t) ÷ 31.1034 × Au Rec × Au Pay × Au price)] ÷ [Cu price (US$/t) × Cu Rec × Cu Pay]. It is Kantra’s view that all metals within this formula will be recovered and sold. Metallurgical recoveries are based on current plant performance. Metal payability is based on current concentrate quality and contracted marketing terms. 11 As at 30 September 2026 Appendix - Kanmantoo Mineral Resources Mine Area JORC Classification Tonnage (kt) Cu (%) Au (g/t) Ag (g/t) Cu Metal (kt) Au Metal (koz) Kavanagh (including Spitfire) Measured 4,600 0.76 0.11 2.2 35 17 Indicated 2,200 0.70 0.11 2.1 16 7.7 Inferred 1 5,200 0.64 0.13 1.9 33 22 Sub-Total 12,000 0.7 0.12 2.1 84 47 North Kavanagh Measured - - - - - - Indicated 280 0.73 0.16 2.8 2.1 1.5 Inferred 2 240 0.67 0.19 2.4 1.6 1.5 Sub-Total 520 0.70 0.18 2.6 3.7 3.0 Nugent Measured 970 0.76 0.39 1.9 7.3 12 Indicated 2,300 0.75 0.35 2.1 17 25 Inferred 3 3,900 0.78 0.35 2.0 30 44 Sub-Total 7,100 0.76 0.35 2.0 55 81 Valentines Measured - - - - - - Indicated 190 0.65 0.07 1.3 1.2 0.41 Inferred 4 190 0.52 0.06 1.1 1.0 0.40 Sub-Total 380 0.58 0.07 1.2 2.2 0.81 Emily Star Measured 140 0.96 0.09 1.8 1.3 0.38 Indicated 2,000 0.74 0.09 1.7 15 5.9 Inferred5 3,900 0.67 0.07 1.4 26 9.1 Sub-Total 6,000 0.70 0.08 1.5 42 15 Critchley Measured 8.4 0.60 0.06 0.8 0.05 0.02 Indicated 380 0.54 0.10 1.2 2.1 1.2 Inferred 140 0.48 0.06 1.2 0.66 0.25 Sub-Total 520 0.53 0.09 1.2 2.8 1.5 TOTAL 27,000 0.71 0.17 1.9 190 150 Notes: 1.
