ASX:CRR announcement 6 August 2025 ASX:CRR 6 Cap Burn – Rise & Shine Analogue New structural model leverages Santana Minerals’ Rise and Shine discovery Cap Burn Project 2020 drilling Breakthrough factors. Santana Minerals’ Rise and Shine discovery came from a renewed structural model, stepping down plunge from surface arsenic-in-soil anomalies and low-grade mineralisation. Persistence Pays. Rise and Shine was discovered (MDD007) in the third exploration phase2. Committed to drilling through barren cover (TZ3 unit). Untapped Potential. Macraes +10 Moz endowment suggests multiple +1 Moz deposits; only Rise and Shine has been discovered. ‘Power of distribution law’ Shareholder Opportunity. Leveraging learnings from Rise and Shine discovery, testing new geological models through systematic exploration. 2.

Growing Demand vs Concentrated Supply from China and Russia - Antimony is critical for the military, manufacturing and renewable energy sectors. - Essential for the energy transition - Expanding applications in batteries and solar panels have intensified demand pressures. - Primarily used as an alloy hardener, flame-retardant agent and a critical component for solar panel glass efficiency and stability. - Photovoltaics sector to become to largest user of antimony. - Antimony is recognised as a top critical raw material/mineral in the EU, US, UK, India, South Korea, Japan and Australia. Supply constraints - driving a significant rise in pricing. - Fragmented market - 83% of antimony production - China, Russia and Tajikistan. - Recent China export controls and mine closures have tightened global supply. - Lack of alternative supply sources. The U.S. and Europe rely heavily on imports, with no major domestic production. - Mining operations outside China fail to meet the growing demand. - Potential for ongoing supply shortages for many years. Rock sample from Mayview Prospect - 27.5 % Sb (MVS16) ASX:CRR announcement - 16 December 2024 ASX:CRR 14 Mavis Lake Project Lithium ONTARIO - CANADA ASX:CRR Mavis Lake - Lithium Strategically important North American lithium resource - Growing 8Mt @ 1.07% Li2O1 lithium resource with substantial expansion potential - Ontario, Canada. - Strategically located to support the North American battery manufacturers. - World Class Infrastructure – excellent access to multiple transport corridors and Hydro/gas power utility networks. - Extensive land holding with numerous drill-ready targets identified – Tot, Gullwing and Corona Prospects - 1st phase metallurgical test work highlighted recoveries up to 87%2, with significant potential to improve process flowsheet. - Studies paused. Continuing low-cost value-adding work-streams in preparation for when markets improve. - North American regional battery/EV production investment exceeds $47 billion. - Canada’s Government has prioritised initiatives to strengthen its critical mineral supply chains and provide a supportive policy environment, such as Ontario’s ‘fast-track’ bill aimed at streamlining the approval process for mining and infrastructure projects.
