A measurement, not an estimate Faster, larger, cleaner and automated CHRYSOS CORPORATION LIMITED | 4 True bulk measurement of large samples, typically 300-500 g Minimal sample preparation e.g. crush to 2-3 mm top-size Non-destructive; no chemical reagents required Quantitative results in as little as two minutes Independent of sample matrix, chemistry or mineralogy Excellent sensitivity: detection limit 0.01 ppm - 10,000 ppm 1. GHD assessment at SGS Kalgoorlie, August 2025 2. Average Emissions (Scope 1+2) Per Sample (kgCO2-e/sample) PhotonAssayTM vs. Fire Assay¹ Fire Assay PhotonAssayTM Time per Sample ➔ ~3-4 Hours ~2 Minutes Sample Size ➔ 10-50g 300-500g CO2 per Sample2 ➔ 2.3kg 0.9kg Hazardous Waste per Sample➔ ~215g 0g Energy Use per Sample ➔ ~8.9kWh ~1.7kWh Automation ➔ No Yes

PhotonAssay removes lead risks from the assay lab No level of lead exposure is acceptable CHRYSOS CORPORATION LIMITED | 5 PhotonAssayTM improves OH&S outcomes through the elimination of hazardous chemicals, lead exposure and the ultra-high temperatures used in conventional fire assay. “There is no known safe blood lead concentration; even blood lead concentrations as low as 3.5 µg/dL may be associated with decreased intelligence in children, behavioural difficulties and learning problems.” WHO, Lead Poisoning - www.who.int/news-room/fact-sheets/detail/lead-poisoning-and-health Fire assayers require routine testing to monitor levels of lead in their blood Fire assayers are routinely rotated through other laboratory tasks to prevent a build-up of lead in their bodies ESG advantages A 2025 GHD study at SGS Kalgoorlie identified three key environmental advantages of PhotonAssay over fire assay: Zero Scope 1* CO₂ emissions ➔ 0 kg of Scope 1 CO₂ emissions ➔ ~2.6x lower emissions per sample across the full process Energy use up to 90% lower ➔ ~10x less energy used during analysis ➔ ~5x less across the full assay process Eliminates lead- contaminated waste ➔ ~215g of contaminated waste per fire assay sample ➔ PhotonAssay generates none * Scope 1 = direct emissions from owned or controlled sources, e.g. on-site furnaces and measured during routine operations Improved OH&S for operators

Partner labs reach many miners; direct deployments embed us at the mine Two routes to market, both driving sample volume Quarterly PhotonAssayTM samples analysed Direct to Mine Deployments bring PhotonAssayTM technology directly to major gold producers, improving mining efficiency with high-quality data. Our Technical Services Team of metallurgists and geologists offers value-added services - ore body analysis, multi-sample testing, and gold, silver, and copper applications - to maximise the benefits of PhotonAssay TM and drive incremental volume. Laboratory partnerships support adoption by local miners and explorers. Sales Managers engage local miners and explorers near hub-and- spoke labs, driving sample volume and PhotonAssay TM adoption. Higher utilization drives gross profit, EBITDA margin, and further lab adoption. Hub & Spoke Deployment Strategy Minesite Deployment Strategy PhotonAssayTM deployed direct to the mine site PhotonAssayTM deployed to hub and spoke laboratories - Miner adoption supported via endorsement by major lab companies - Impacted by macro trends with potential volatility in sample volumes - Samples span the breadth of a miner; exploration, mining, processing - Strong relationships with the miner and upside volume potential Two-pronged sales approach CHRYSOS CORPORATION LIMITED | 9 - 500,000 1,000,000 1,500,000 2,000,000 2,500,000 3,000,000 3,500,000 Laboratory Mine Site
