Slide 4: A Profitable Near-Term Gold Producer
A Profitable Near-Term Gold Producer … • Near-term production pathway: Low-cost and near-term development of the ~2Moz Grosvenor and Peak Hill gold projects, with high-recovery processing via existing Carbon-in-Leach plant, supplemented by new Heap Leach operations • Compelling financial model: Init
Slide 5: With a Known ~2Moz Gold Inventory
With a Known ~2Moz Gold Inventory … • JORC compliant gold resources of ~2Moz: The current resource base has clear potential to expand by extensional and step-out drilling of known deposits • Significant scope for near-mine discoveries: The district has proven gold mineralisation but is under-explore
Slide 6: And Significant Exploration Potential
… And Significant Exploration Potential • Dominant 1,866km2 holding in a proven mineralised province: RNI has consolidated six well-defined project areas in the Bryah Basin to build a dominant tenement package • Projects supported by historical geological data sets covering ~25 years of exploration
Slide 7: The Near-Term Pathway to Gold Production
The Near-Term Pathway to Gold Production • Independent feasibility studies confirm low-cost and near-term gold production pathway for the ~2Moz Grosvenor and Peak Hill gold projects • Studies confirm robust & sustainable returns (EBITDA ~$260m) over first 8 years, averaging 68koz with low cash opex
Slide 8: Feasibility Studies – Key Outcomes
Feasibility Studies – Key Outcomes • Parallel processing options including conventional CIL through RNI’s existing Grosvenor gold plant and HL processing of lower-grade material • Grosvenor CIL nameplate ~1Mtpa, project processing rate is ~1.4Mtpa over 8 years (CIL and HL) • First production schedul

Grosvenor CIL Gold Plant • 1Mtpa nameplate Grosvenor CIL gold processing plant - 100% owned by RNI • Low completion capex – Just ~$3.8m required to restart • Permitting processes almost complete , major approvals from WA Government received • Supporting infrastructure in place including camp, airfie
Slide 14: Exploration Overview
Exploration Overview • A dominant 1,866km2 regional portfolio in a known exploration hot spot • Six key consolidated project areas – all prospective for copper and gold • Pipeline of well-defined priority targets, including Forrest Gimp, Wodger, Big Billy, Orient, Horseshoe Lights East, Morck’s Well
Slide 15: Bryah Basin Copper - 120km of VHMS Targets
Bryah Basin Copper - 120km of VHMS Targets • RNI tenement package includes ~120 strike km of VHMS target horizons, highly prospective for copper 15
Slide 16: Forrest Gimp – An Exciting Copper-Gold Discovery
Forrest Gimp – An Exciting Copper-Gold Discovery • Copper-gold discovery of up to 5.4% Cu beneath gold rich cap • Open in all directions. Within a priority 8km VHMS trend • Based on re-evaluation of historical drilling. No previous Cu assays 16 • Geochemistry consistent with VHMS deposit
Slide 17: The 12km Corridor of Riches – Priority Targets
The 12km Corridor of Riches – Priority Targets • High-grade copper results up to 13.8% on an 8km geological VHMS trend stretching from Big Billy to Forrest Gimp. Anomalous base metal results encountered a further 4km north at Callies for a total 12km strike length • Priority drilling and exploration
Slide 18: Bryah Basin – Strategic Exploration Proposition
Bryah Basin – Strategic Exploration Proposition • Prospectivity of the Bryah Basin to host quality copper deposits is proven (DeGrussa, Horseshoe Lights, Horseshoe etc) • Corporate consolidation of tenement ownership is accelerating (SFR, IGO, TLM, VRX, ALY) • RNI is the dominant tenement holder and
