With a strong board and management team that has extensive experience in Africa, the company is well funded for an aggressive exploration program throughout fiscal year 2026. ASX:DY6 Figure: A coarse rutile nugget (~4 cm) exhibiting a massive texture, sub-metallic luster, and black coloration with secondary Fe-oxides and subrounded crystals, suggesting limited lateral transport. It was recovered from residual regolith composed primarily of fine-grained, iron-rich soil and clay near a road cutting at the sample site GRMAU0012 (not assayed). For detailed nugget analysis, refer to ASX announcement: 11 August 2025 - XRF Analysis confirms highquality of natural rutile. Cautionary Statement: The rutile nugget is presented solely as a display specimen and does not reflect in-situ mineralisation or assay outcomes. 4 Investment Snapshot ASX:DY6 100% owned projects with no royalties Access to key infrastructure (rail, ports, power) Central Rutile Project – district scale (~5,900km2) Natural Rutile – purest form of titanium Cameroon – significantly underexplored Strong board & management with significant African experience 3 highly prospective REE projects in Malawi Fully funded for high-impact exploration throughout FY26 Figures: (Top left) – DY6 geologist inspecting auger samples NSIAU000013, (Top right) – Example saprolite material from 8-9m . Refer to ASX announcement: 29 July 2025 Central Rutile Project exploration update (Bottom) – Auger samples being dried prior to despatch for laboratory analysis Cautionary Statement: The images shown are for illustrative purposes only, depicting auger drilling and sampling techniques. This is not indicative of any mineralisation, resources or reserves, and should not be relied upon as a measure of economic potential. Assay results from further the drilling and sampling programmes will be required to understand the grade and extent of mineralisation. Initial assay results are expected in Q4 2025. 5 African Based Portfolio of Critical Minerals Assets Cameroon Rutile Projects: Flagship Central Rutile Project covers approximately 5,900 km², while the Douala Basin Heavy Mineral Sands (HMS) project covers 2,580 km² and is located within 50 km of the deep-water port of Douala. Malawi REE Projects: In Malawi, the company has three highly prospective REE projects: Tundulu (light REEs, gallium, and rock phosphate), Machinga (HREEs and niobium), and Salambidwe (REEs and niobium). High-Value Minerals: Rutile is the purest and most valuable naturally occurring form of titanium, with applications in aerospace, defense, and pigment manufacturing. Global supply is projected to decline sharply, making new deposits highly sought after. ASX:DY6 Cameroon Malawi 6 Rutile: The Most Valuable Titanium Mineral Rutile is a key source of titanium, a highly versatile and high-demand metal. It’s the highest-grade and most naturally occurring form of titanium dioxide. Strong industrial demand: Titanium's exceptional strength-to-weight ratio and high corrosion resistance make it essential for various applications. It's used in pigments (paints and plastics), aerospace, medicine (implants), and technology. Growing Market: The demand for titanium is expected to rise due to increasing global infrastructural development and through increasing industrial applications. Limited Supply: Despite its widespread use, new high-grade deposits of rutile are limited, which could lead to increased value over time. Outside of Sovereign Metals’ Kasiya Rutile Project in Malawi there are limited new deposits forecast to come online in the near term. ASX:DY6 7 Central Rutile Project: World Class Potential The Central Rutile Project in Cameroon has the key ingredients to become a world-class rutile deposit. The project is analogous to Sovereign Metals’ Tier 1 Kasiya deposit in Malawi, the world’s largest primary rutile deposit. District Scale: 14 exploration permits under valid applications covering ~5,900 km². Favourable Geology: The project is underlain by kyanite-bearing mica schist, which is the source rock for the rutile. Deep Weathering Profile: Deep, intense weathering has concentrated and upgraded the rutile into a high-grade layer of saprolite, which is easier to mine. Historical Evidence: Historical production from the area (1935-1955) recorded 15,000 tons of high-purity rutile (>95%). Promising Neighbours: The project borders Lion Rock Mineral’s Minta Rutile Project, where initial sampling has shown high-value mineral assemblages with valuable heavy minerals (VHM) up to 93% of total heavy minerals (THM) and with the dominant VHM’s being rutile (up to 69.8%), monazite (up to 35.6%) and zircon (up to 21.5%). ASX:DY6 DY6’s Central Rutile Project comprises 14 licence blocks in Cameroon’s central region 8 Central Rutile Project: First pass reconnaissance assay results Significant Mineralisation Confirmed • Initial reconnaissance sampling confirmed high grade residual rutile mineralisation • Validation of geological model targeting Tier 1 residual rutile deposits • Ultra-high grade rutile including 1.57% and 2.1% rutile • Several ore-grade rutile occurrences (>0.7%+) • Notable assays: o 2.25m @ 8.7% HM incl. 0.6% rutile o 3.5m @ 5.29% HM incl. 0.78% rutile o 5.8m @ 6.98% HM incl. 0.47% rutile o 4.8m @ 4.99% HM incl. 0.3% rutile o 0.8m @ 2.81% HM incl. 0.66% rutile o 1.35m @ 1,23% HM incl. 0.84% rutile ASX:DY6 Figure : Zoomed in geological map of the Nsimbo and Alamba licences showing the recently completed reconnaissance sampling campaign and 41km strike of high-grade mineralisation. 9 Central Rutile Project: Assay Results Continued District Scale Potential Confirmed • Samples comprised channel samples of roadcutting exposures and very shallow auger holes • District scale of rutile mineralisation – 41km distance between mineralised samples • 24-hole, 237.9m reconnaissance drilling campaign completed (9.9m average hole depth) • Holes displayed same weathering profile as Kasiya, with visual HM in panned samples • Samples currently being prepped; assays expected in 6 weeks Figure: Weathering profile at the Bounde licence showing a classic residual “Kasiya-type” profile ASX:DY6 10 Central Rutile Project Seeing the right ‘ingredients’ Figure: Fine-grained heavy mineral (HM) and rutile grains (~1 mm) recovered from a panned concentrate of auger hole GRMAU0004 (not assayed).

The tenements are all located within 50km of the deep-water port city of Douala. Geologically the Douala Basin is a coastal sedimentary basin consisting of a package of mainly marine sedimentary formations The Diwong licence was previously known as the Missole Project which was held by the French multinational Eramet. Historical sonic drilling at Douala by Eramet delivered significant intercepts from the Diwong licence, including: o 10m @ 5.0% THM from surface (DIB_S00024) o 12m @ 4.7% THM from surface (DIB_S00018) o 7.7m @ 4.0% THM from surface (DIB_S00022) o 18m @ 3.7% THM from surface, ending in mineralisation (DIB_S00010) ASX:DY6 DY6’s Douala Basin Project comprises 6 licence blocks proximal to the port city of Douala along Cameroon’s coast 09 12 Rutile Peers Sovereign Minerals Sierra Rutile Lion Rock Minerals DY6 Metals Market Cap $440m N/A ~$163m ~$19m Country Malawi Sierra Leone Cameroon Cameroon Ownership 100% 100% 80% 100% Landholding Size ~786km2 559km2 8,800km2 5,901km2 Stage of development DFS – pre-development Operating Exploration Exploration Bedrock geology High-grade mica-schist Alluvial placer High-grade mica-schist High-grade mica-schist Style of mineralisation Saprolite-hosted, residual rutile Alluvial placer Saprolite-hosted, residual rutile Saprolite-hosted, residual rutile Resource Grade/Size 1.8Bt @ 1% rutile 0.78Bt @ 1.04% rutile N/A N/A Notable residual intercepts N/A N/A • 4m @ 1.57% HM, inc 1.05% rutile • 5.65m @ 5.2% HM • 7m @ 5.1% HM • 5.8m @ 6.98% HM, inc 0.47% rutile (channel) • 3.5m @ 5.29% HM, inc 0.78% rutile (channel) • 2.25m @ 8.7% HM, inc 0.6% rutile (auger) Market caps - as at 2 September 2025 Resources / grades: • Sovereign Metals - https://api.investi.com.au/api/announcements/svm/a75dced1-d48.pdf • Sierra Rutile - https://sierra-rutile.com/media/nqcbj0ij/srx-2022-resources-and-reserves-statement-final.pdf • Lion Rock - https://cdn-api.markitdigital.com/apiman-gateway/ASX/asx-research/1.0/file/2924-02963007-6A1271135&v=c2533a54e2514fb77a8f93f84db686e1125273e9 and https://cdn-api.markitdigital.com/apiman-gateway/ASX/asx-research/1.0/file/2924-029487336A1265374&v=c2533a54e2514fb77a8f93f84db686e1125273e9 • Dy6 - https://investors.dy6metals.com/announcements/7135080 ASX:DY6 13 Cameroon – Next steps DY6 is fully-funded to undertake an aggressive exploration programme across the Company’s Central Rutile and Douala Basin projects.
