He has worked on the ground in the Guiana Shield, he built the geological and structural model at Oko West, and he has taken projects from first-pass targeting through to resource drilling. With Mauricio in place, we can move quickly – planning is already under way to have soil samplers on the ground at Gadu Manda in December, so we start 2027 with results in hand as our in-country team starts. Our approach is simple: secure good ground on sensible terms, explore it systematically and at low cost, and let the results decide where we drill. We look forward to updating shareholders as the program gets under way.’ Figure 1 – Location of the Gadu Manda, Greenstars and Gonini Gold Projects and other gold deposits within the Suriname greenstone belt.

APPOINTMENT OF EXPERIENCED STRUCTURAL GEOLOGIST Mr Felmer is a professional geologist with more than 23 years’ experience in mineral exploration, mine geology and structural geology. He has worked on more than 70 exploration projects and mine sites, mostly in remote and challenging environments, in Brazil, Chile, Guyana, Suriname, Mozambique, Zimbabwe, South Africa, Zambia, Saudi Arabia and Pakistan. His track record includes three mineral discoveries from regional targets (gold and nickel-PGE in Brazil, and copper in Pakistan).

His earlier gold experience in the Brazilian Amazon includes the Volta Grande gold project (Belo Sun Mining), where he planned and supervised a 250,000 m infill resource drilling program, the Aurizona gold mine (Luna Gold, now Equinox Gold) and the Tucano gold mine (Beadell Resources). Since 2025 he has provided project evaluation services across the Guiana Shield, including in Suriname. Mr Felmer holds a Bachelor of Science in Geology from the University of São Paulo and a Master of Science in Economic Geology from the Federal University of Minas Gerais. He is a Member of the Australian Institute of Geoscientists (MAIG) and the Society of Economic Geologists, and is fluent in Spanish, Portuguese and English. STRUCTURAL TARGETING – GEXPLORE GexplOre’s structural study over the Company’s Suriname projects is under way. GexplOre is a team of Guiana Shield exploration specialists who have worked on around 20 gold projects across the Shield, including structural work at Oko West in Guyana and Antino in Suriname. The study is led by Dr Brice Lacroix, PhD, P.Geo., co-founder of GexplOre (see ASX announcement dated 5 October 2026). Gold in Suriname’s greenstone belts is mainly controlled by shear zones, fold hinges and granitoid–greenstone contacts. Deep weathering and forest cover mean outcrop is scarce, so satellite-based structural interpretation is a fast, low-cost first filter before field programs begin. GexplOre is processing SRTM elevation data and ASTER multispectral data to map host rocks, shear and fault corridors, and later folding events. The work is in two stages: – Stage 1: a detailed, property-scale interpretation of two priority areas at the Gonini Gold Project, expected in mid-November 2026. – Stage 2: a regional, lower-resolution review of more than 6,000 km² of the surrounding greenstone belt. This will help the Company rank its projects and screen further opportunities. Mr Felmer will combine GexplOre’s interpretation with historical data, GMD regional mapping and the locations of artisanal workings to rank targets. Those rankings will set the soil sampling grids, mapping and auger programs from 2027. INITIAL EXPLORATION PROGRAM Planning is under way for the Company’s first field program in Suriname, a first-pass sampling program scheduled to start in December 2026 at the Gadu Manda Gold Project. Third-party small-scale alluvial workings are present on the Gadu Manda right; the program is designed to identify where gold anomalism in soils may point to bedrock sources beneath the weathered profile. The program will use hand-auger sampling into the B horizon (approximately 1 m depth) on a systematic grid, with sampling, QA/QC and data management protocols. Fieldwork will be carried out with local contractors. Results from the December program are intended to guide follow-up mapping, infill soil sampling and auger drilling from January 2027, when the Company’s field team mobilises across the portfolio.

Figure 2 – Third-party small-scale alluvial gold workings and camp on the northern block of the Gonini Gold Project, looking east. SURINAME AND PROJECT OVERVIEW Suriname lies on the north-east coast of South America, between Guyana and French Guiana. It sits within the Guiana Shield, a Palaeoproterozoic granite–greenstone terrane that hosts Zijin Mining’s Rosebel and Newmont’s Merian gold mines in Suriname, and the Oko West gold deposit in neighbouring Guyana. Gold is one of Suriname’s principal exports, and mineral rights are granted under the Mining Decree 1986. Despite its production history, large parts of Suriname’s greenstone belts have seen limited modern, systematic exploration. Critical Resources Limited – www.criticalresources.com.au Level 45, 108 St George's Tce, Perth WA 6000 P: +61 (8) 9465 1024 E: info@criticalresources.com.au ASX:CRR Subject to completion of the announced transactions, the Company’s Suriname portfolio will comprise of three gold projects covering approximately 228 km² of granted gold rights: – Gonini Gold Project (90% acquisition): two granted rights of exploitation covering approximately 164 km² in the Sara Creek district, valid to August 2030. – Greenstars Gold Project (90% acquisition): a granted gold right covering approximately 35 km² in the Para district, west of the Saramacca River. – Gadu Manda Gold Project (90% acquisition): a granted right of exploration covering approximately 29 km² in the Brokopondo district, approximately 4 km west of the open pits of the Rosebel gold mine. Further details of each project are set out in the Company’s ASX announcements of September and October 2026. SURINAME STRATEGY The Company’s objective is to build a significant gold exploration and development business in Suriname. It aspires to grow the portfolio from three to four or five gold projects, focused on two exploration centres: the Sara Creek district and the area west of the Rosebel gold mine. Exploration will be systematic and low-cost, testing targets with soil sampling, mapping and auger drilling before committing to drilling. The work will be carried out by a small in-country technical team working with local contractors and existing camp infrastructure, through a Suriname subsidiary the Company is establishing. There is no certainty that future discussions will result in new project acquisitions. APPOINTMENT TERMS The Company has entered into a Consulting Services Agreement with Mr Felmer, under which geological services are provided on a consultancy basis for a monthly retainer. The Company intends to offer Mr Felmer full-time employment as Exploration Manager – Suriname, with a target start in January 2027, subject to Board approval and agreement of employment terms. Mr Felmer may be invited to participate in the Company’s Employee Share Incentive Plan, subject to any required shareholder and regulatory approvals. No securities are being issued in connection with the appointment. Mr Felmer is not a Director or related party of the Company.
