Announcement PDF ASX ANNOUNCEMENT 12 October 2026 Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St Georges Terrace, Perth WA 6000 P: +61 (8) 9465 1024 E: info@criticalresources.com.au ASX:CRR SURINAME GOLD PROJECTS: DUE DILIGENCE ADVANCING TO FAST-TRACK EXPLORATION PROGRAMS Due diligence fast-tracked across both the Gonini and Greenstars Gold Projects to allow immediate execution of the exploration strategy upon satisfaction of the conditions precedent, with management commencing site visits and in-country meetings with key officials. - Management in Suriname. Management is in Suriname visiting the Gonini and Greenstars Gold Projects, progressing legal, title and technical due diligence with the vendors, in-country counsel and advisers, meeting local communities and key officials, and planning the first field programs. - ~199 km² of granted gold mining rights. Gonini lies in the historic Sara Creek district, where gold has been mined for 150 years, approximately 66 km from Newmont’s Merian mine. Greenstars lies approximately 35 km west of Zijin’s Rosebel mine, which has reportedly produced more than 5.65 Moz of gold since 20041,2,6. - Field crew mobilising. The Company is finalising its exploration programs and assembling a field crew to undertake verification sampling at Greenstars and first-pass sampling at Gonini1,2. - Due diligence advancing. Legal, title and technical due diligence is advancing at Gonini (~164 km²) and Greenstars (~35 km²), alongside the preparation of binding agreements with both vendors, to allow exploration programs to start as soon as the conditions precedent are satisfied1,2. - Structural targeting under way. Guiana Shield structural specialists have been engaged to provide structural interpretation that will focus field programs. Suriname's orogenic gold is concentrated along shear zones, fold hinges and greenstone contacts. Mapping these controls is fundamental to effective exploration in deeply weathered terrain, where outcrop is scarce3,9. - Actively growing the land position. CRR continues to actively assess further opportunities across Suriname to expand the ~199 km² of granted gold mining rights, subject to completion of the acquisitions1,2. - A proven gold jurisdiction. Suriname hosts Zijin’s Rosebel and Newmont’s Merian mines, with more than two decades of continuous large-scale gold production. Gold accounted for ~79% of Suriname’s exports (~US$2.0 billion) in 20246,8. - Global gold capital is moving into Suriname. Gold Fields completed a C$77 million investment in Founders Metals in September 2026 to hold ~19.9%, and La Mancha holds 19.9% of both Miata Metals and Greenheart Gold – all Canadian-listed explorers in the same Suriname greenstone belt4,5,7. - Rare ASX exposure to a highly under-explored greenstone belt. The Guiana Shield shares its gold- bearing geology with West Africa’s Birimian greenstone belts, but has seen materially less systematic modern exploration4,9. Critical Resources Limited (ASX: CRR) (Critical Resources or the Company) is pleased to provide an update on its Suriname gold projects interests, following the announcement of the Gonini Gold Project (Gonini) on 23 September 2026 and the Greenstars Gold Project (Greenstars) on 28 September 20261,2. Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St Georges Terrace, Perth WA 6000 P: +61 (8) 9465 1024 E: info@criticalresources.com.au ASX:CRR The Company’s objective in Suriname is to build a portfolio of granted gold projects in one of South America’s most active gold exploration jurisdictions, and to move quickly from securing title to systematic exploration on the ground. Both projects are at an early stage. The coming weeks will be an important period, with management on site and establishing an in-country presence to begin first-pass sampling. Figure 1 – Location of the Gonini and Greenstars Gold Projects and other gold occurrences within Suriname and the greenstone belt. Critical Resources Managing Director, Tim Wither, commented: ‘Suriname is a relatively unknown but proven gold jurisdiction, and is attracting serious capital from some of the world’s leading gold investors. In a matter of weeks, we have secured exclusivity over two granted gold projects, and we are now on the ground. Our meetings with our vendors, partners and service providers give us great confidence that we can build a strong in-country team to rapidly advance systematic exploration across Gonini and Greenstars, and across other projects we may be able to bring into our Suriname portfolio. ‘Our partners have been very supportive, giving us introductions to key personnel, legal counsel, business administrators and bankers, and access to logistics and exploration teams. Our vendors are valuable partners who are equally invested in the success of our projects and in building an experienced in-country team of technical and exploration personnel. ‘This visit lets us meet our vendors and local communities first-hand, and set up the field programs, with a crew being organised to mobilise in the coming weeks, subject to finalisation. We continue to fast-track the due diligence on Gonini and Greenstars so that we can get boots on the ground as soon as practicable, and being here in Suriname with our vendors, counsel and advisers is the most direct way to Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St Georges Terrace, Perth WA 6000 P: +61 (8) 9465 1024 E: info@criticalresources.com.au ASX:CRR do that. It is early days, but we are very excited to be starting exploration in Suriname. We are also actively looking at further opportunities to grow our position in the country – the Gonini and Greenstars projects provide a solid foundation on which to build.’ SURINAME A proven producing jurisdiction. Rosebel (Zijin, in production since 2004) and Merian (Newmont, in production since 2016) have underpinned more than two decades of large-scale gold mining in Suriname. Rosebel reportedly produced 5.65 Moz of gold between 2004 and 2021 and 306,535 oz in 2025, and was acquired by Zijin for US$360 million in 2023. Global gold capital is moving into Suriname. Gold Fields completed a C$77 million investment in Founders Metals in September 2026, lifting its stake to approximately 19.9%. La Mancha holds 19.9% of Miata Metals, following a C$25.2 million financing in August 2026, and 19.9% of Greenheart Gold4,5,7. These transactions show growing investor interest in Suriname’s gold exploration sector, without implying a comparable outcome for CRR. The South American counterpart to West Africa’s Birimian. The Guiana Shield and the West African Birimian Shield are interpreted to have been joined before the Atlantic opened and share comparable gold-bearing geology. The Birimian hosts an estimated 500+ Moz of discovered gold and the Guiana Shield around 100 Moz, reflecting materially less systematic modern exploration4,9. An ASX first mover. Based on the Company’s review, no other ASX-listed Australian company holds rights to granted gold tenure in Suriname, giving Australian investors rare listed exposure to the region2.

Third-party information has not been independently verified by Critical Resources and is provided for regional and jurisdictional context only. Results from other projects are not indicative of mineralisation at Gonini or Greenstars. TWO COMPLEMENTARY GRANTED GOLD PROJECTS Gonini Gold Project (~164 km²). Two granted exploitation rights in the historic Sara Creek district, where gold was discovered in 1876, within the Marowijne greenstone belt, approximately 66 km from Newmont’s Merian mine. Generations of small-scale miners have worked the district, but there is no record of modern systematic exploration on the Gonini rights1,9. Greenstars Gold Project (~35 km²). A single granted exploitation right in the Para District, road-accessible from Paramaribo and approximately 35 km west of Zijin’s Rosebel gold mine, with active small-scale alluvial workings in the project area2. Both acquisitions are staged, with most of the consideration deferred and conditional on completion. The key commercial terms are summarised in the Company’s announcements of 23 and 28 September 20261,2.

DUE DILIGENCE FAST-TRACKED Critical Resources management is currently in Suriname, commencing site visits, in-country meetings with key officials and preparations for the first field programs. The planned activities include: - Gonini site inspection. Inspection of both exploitation rights in the historic Sara Creek district, including the existing artisanal workings, access and camp infrastructure. - Greenstars site inspection. Inspection of the right and its road access from Paramaribo, the small-scale alluvial workings and the two areas identified by the Vendor as prospective, ahead of verification sampling during due diligence. - Field crew and logistics. Planning field logistics, site access and camp arrangements for the field crew being organised to mobilise in the coming weeks. - Stakeholders and set-up. Meeting with the vendors, local communities, relevant government agencies and the Company’s in-country advisers, and progressing the establishment of the Company’s Suriname operating entity. Once mobilised, the field crew will commence verification sampling at Greenstars and first-pass sampling at Gonini. Subject to completion, the Company then intends to run first-pass soil and auger geochemistry across interpreted prospective geological contacts at both projects1,2. The Company’s strategy is to build a portfolio of gold projects in the Suriname greenstone belt that can be explored efficiently and acquired on staged terms. Gonini and Greenstars provide the foundation for that Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St Georges Terrace, Perth WA 6000 P: +61 (8) 9465 1024 E: info@criticalresources.com.au ASX:CRR portfolio. The Company continues to actively review further opportunities across Suriname to expand its interests, and will pursue only those that meet its criteria for title, access and cost of entry. The Company will keep the market informed in accordance with its continuous disclosure obligations.
