State again recognised as a Top 10 jurisdiction for Mining Investment Attractiveness. Top 10 jurisdiction Mining Investment Attractiveness 6 DELIVERING BENEFIT TO LOCAL COMMUNITY ✓ Community support built over 20 years of genuine engagement 7 EXISTING INFRASTRUCTURE ✓ 3.6Mtpa processing plant. ✓ TSF with sufficient capacity for Stage 1 mine plan plus a further 3Mt. ✓ 360m deep pit enabling fast lowcost access to mineral lodes. ✓ Combined infrastructure at Kanmantoo cost >$200m in ~2010. 8 TWO STAGE STRATEGY - 1. GENERATE CASH, 2. GROW STAGE 1 ✓ Maintain infrastructure in operational state to keep capital hurdle for underground low. ✓ This resulted in underground being one of the lowest capital intensive copper development projects in the world. ✓ Maintaining the plant ready for restart requires high C&M costs so strategy was to spend just enough on drilling to develop a mine plan sufficiently robust to finance and return to cash generation ASAP. 9 TWO STAGE STRATEGY - 1. GENERATE CASH, 2. GROW STAGE 2 ✓ Focus on returning to cash generation quickly limited drilling to only 2 mineral lodes, Kavanagh and Nugent. Current Mine Plan ✓ These areas remain open at depth and along strike. ✓ There are a further 7 areas which were drilled and/or partially mined as part of open pit. ✓ Focus now turns to expanding mine life and annual throughput by converting these areas. 10 STAGE 1 MINE PLAN The mine plan and associated economics is based on the Economic Assessment released to the ASX on 27 February 2023. It does not include an update to the Nugent Resource model reported to the ASX 26 July 2022 which increased the total copper metal from 8.7kt to 15kt as reported in the table above. It also does not include drilling during 2023 and the identification of a fault in Kavanagh which truncates mineralisation to the north, both of which are expected to result in a material change to the Mineral Resource Estimate and project economics in the Economic Assessment. The Production Target and financial forecasts presented in the Economic Assessment are shown on a 100% Project basis. The Production Target underpinning the Base Case financial forecasts included in the Economic Assessment comprises 74% Measured and Indicated Resources, and 26% Inferred Resources. There is a lower level of geological and grade continuity confidence associated with Inferred Resources and there is no certainty that further exploration work will result in the conversion of Inferred Resource estimates to Indicated 11 Resource estimates or return the same grade and tonnage distribution. UNDERGROUND PRODUCTION RAMPING UP ✓ All people & plant on site. ✓ Underground development in line with planned schedule and costs. ✓ Major projects completed on time and budget (ventilation, electricity, dewatering system). ✓ Production profile ramps up as additional work areas open and multiple stopes are mined concurrently. 12 PROCESSING PLANT COMMISSIONED ✓ 3.6Mtpa processing plant commissioned in Q1-24. ✓ Large inventory of critical spares on site mitigates risk of extended downtime. ✓ Long term electricity contract locks in low-cost power until 2027. 13 FIRST COPPER PRODUCTION ✓ Copper sales in Q1-24 return business to cash generation. ✓ 16kt hedging facility available. Currently 3kt hedged at average realised price of $12,500/ tonne. ✓ Copper production profile ramps up as the underground develops. 14 STAGE 2 - GROWING LIFE & COPPER PRODUCTION ✓ Mine life limited by drilling density. ✓ Exploration Target 60 - 100 Mt 0.9 - 1.2% Cu 0.1 - 0.2g/t Au Refer ASX Announcement 11 October 2023. The Exploration Target is conceptual in nature as there has been insufficient exploration to define a Mineral Resource. It is uncertain if further exploration will result in the determination of a Mineral Resource under the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, the JORC Code” (JORC 2012). The Exploration Target is not being reported as part of any Mineral Resource or Ore Reserve. 15 >100% EXPLORATION STRIKE RATE ✓ Mineralisation continuity down dip has resulted in high strike rate since 2019: 139 holes 163 intersections Cu-Au ✓ Drilling has resulted in >600% increase in Mineral Resource Estimate (MRE) ✓ >25,000 assays from drilling not yet in the MRE (increasing from 16,481 assays to over 41,500 assays) 16 MINERAL RESOURCE ESTIMATE BEING UPDATED ✓ Update to include maiden MRE for Emily Star & North Kavanagh, and update existing Kavanagh MRE. Current Mine Plan ✓ Total MRE expected to increase. ✓ Drilling identified a fault that truncates Kavanagh mineralisation to the north and is expected to reduce the MRE in this area. ✓ Spitfire will partly offset, but net reduction to Kavanagh MRE expected which may materially impact planned mining inventory. ✓ Reviewing Emily Star and North Kavanagh as additional work areas. 17 MINE EXTENSION - KAVANAGH ✓ Mine plan limited by drilling. ✓ Deepest holes more than 200m below the extent of the current mine plan highlight that mineralisation is continuing at depth (800m below surface and open). ✓ Recent Kavanagh holes include: 36.6m @ 3.35% Cu . from 43m downhole (23KVUG064). 40m @ 1.27% Cu . from 43m downhole (23KVUG072). 33.23m @ 1.46% Cu . from 42m downhole (23KVUG083). 18 Refer ASX Announcements 1 September 2021, 11 May 2022, 13 November 2023 MINE EXTENSION - SPITFIRE ✓ 45.4m @ 1.19% Cu, 0.12 g/t Au from 428.5m downhole (KTDD243_W1). ✓ Nearest hole > 100m. ✓ Follow up drilling confirms Spitfire zone extending down dip and along strike. ✓ Spitfire being modelled in MRE update, however drill results to date have already warranted moving the decline further north to accommodate the growing Spitfire mineral lode. Refer ASX Announcement 28 August 2023 19 MINE EXTENSION - EMILY STAR ✓ Mineralisation continues through base off the open pit. ✓ 71.7m @ 0.89% Cu from 132.7m downhole (KTDD239) ✓ 68.7m @ 0.9% Cu from 158.6m downhole (KTDD240), including; ✓ 35m @ 1.29% Cu from 192.2m downhole ✓ Emily Star sits within 300m of the portal, providing opportunity to develop a separate work area. ✓ Maiden MRE being developed. Refer ASX Announcement 3 July 2023 20 MINE EXTENSION - PARINGA ✓ 17m @ 3.6% Cu, 0.6g/t Au from 144m downhole (KTRC954) ✓ 14m @ 2.8% Cu, 0.3g/t Au from 123m downhole (KTRC866); ✓ Mineralisation occurring over 100m down dip and still open. ✓ Immediately adjacent to Emily Star with potential to share underground development infrastructure. Refer ASX Announcement 27 September 2019 21 GAME CHANGER - KANMANTOO DEEPS ✓ Large low resistivity (high conductivity) anomaly coincident with magnetic and gravity highs. ✓ Very similar geophysical signature to the main Kanmantoo zone. ✓ Potential extension of the Kanmantoo mineral system that has been offset down fault. ✓ Within 400m of the underground decline that is being developed. Refer ASX Announcement 11 October 2023 22 SPARE CAPACITY TO RAMP UP COPPER PRODUCTION… ✓ 3.6Mtpa processing plant only ~40% utilised. ✓ Mineralised zones generally characterised by high grade core with lower grade halo. ✓ As price moves up, Hillgrove can quickly respond by widening stopes to present more ore to the process plant that has ample capacity to quickly convert to copper and cash. ✓ Highly leveraged to copper price. 23 …AND CONVERT EXPLORATION SUCCESS ✓ Latent capacity enables Hillgrove to convert exploration success to copper with no processing capex. ✓ Increase in annual copper production reduces AISC. ✓ Majority of operational costs are fixed in nature so any additional copper is high margin and has outsized impact to cash flow. ✓ Plant capacity > 30ktpa. 24 FIRST COPPER PRODUCTION IS JUST THE BEGINNING ✓ Transitioning from Explorer to Producer on schedule and in line with costs demonstrates Hillgrove’s capability to deliver. ✓ Kanmantoo is limited by the extent of drilling with all on-lease mineral zones remaining open down dip and along strike. ✓ Next Steps: increasing mine life and annual throughput. 25 Appendix 26 REFERENCES All exploration drill results, exploration information and Mineral Resource Estimates have previously been reported to the ASX by Competent Person at the time.
