Announcement PDF ASX Announcement 19 September 2023 Exceptional Lithium Results from Swell Zone Drilling with 65.45m grading up to 1.39% Li2O and 50.2m @ 1.28% Li2O Highlights • Exceptional new results from drilling following up the recently reported results from drill-hole MF23-207 (74.4m @ 1.18% Li2O including 32.95m @ 1.81% Li2O). • Drill holes testing the Swell Zone both East and West of MF23-207 have continued to intersect large, high-grade intervals of mineralisation, providing a greater level of confidence that the thick, high-grade mineralisation extends over a 200m strike. • Assays confirm: - Drill-hole MF23-213 with 50.2m @ 1.28% Li2O from 203.6m down-hole, including multiple meter-wide segments of extremely high-grade spodumene mineralisation, from 2.11% Li2O to 4.18% Li2O. - Drill-hole MF23-214 with 65.45m @ 0.84% Li2O from 186.25m down-hole, including 55m @ 0.95% Li2O from 194m down-hole, including 25.85m @ 1.30% Li2O from 214m down-hole. • Permit approval for further drill pads to continue testing the Swell Zone are expected imminently, allowing follow-up drilling to commence in the coming weeks. • All drilling results are rapidly adding tonnage to the existing Resource, putting the Company on track for a major Resource upgrade in H1 2024. Lithium exploration and project development company Critical Resources Limited ASX:CRR (“Critical Resources” or “the Company”) is pleased to report exceptional new thick, high-grade results from ongoing following drilling around the recent breakthrough drill-hole MF23-207, with assays continuing to validate and expand the recently discovered “Swell Zone” at the Mavis Lake Lithium Project in Ontario, Canada. Critical Resources Managing Director, Alex Cheeseman said: “These outstanding results in terms of both thickness and grade provide further evidence that the Mavis Lake Swell Zone is a game-changing discovery for the Company. “Continued wide, high-grade results make it clear that Mavis Lake is a project with significant potential. Its location, within 10km of the City of Dryden, immediate access to world-class infrastructure and the surrounding automotive industries in Southern Ontario and Michigan State, make this a project of strategic importance.” Critical Resources Limited ABN 12 145 184 667 ASX:CRR Level 50, 108 St Georges Terrace, Perth WA 6000 P. +61 9389 4499 W. criticalresources.com.au E. info@criticalresources.com.au Exploration Overview Drilling has been designed to continue to test the Swell Zone both east and west of Drill Hole MF23207, within the limits of current approved drill pads. Assay results have confirmed that the Swell Zone has a current strike of 200m, showing consistency of mineralisation thickness (from 50m to 74m) and also consistency of grade (from 0.84% Li2O to 1.28% Li2O), including localised peaks of extremely high grade up to 4.18% Li2O. Current drilling forms part of the 2023 resource extension drilling program, seeking to establish Mavis Lake as the largest single-site, JORC Code 2012 Compliant Lithium Resource in Ontario. Full exploration results are provided in Appendix 1. Demonstrating Consistency in the Swell Zone The outstanding high-grade assays and broad zones of mineralisation in MF23-213 and MF23-214 extend the Swell Zone laterally while continuing to solidify the significance of the Swell Zone. Figure 1 shows the Plan view of the key intercepts in the Swell Zone, with Figures 2 and 3, a long section and cross section respectively, showing Swell consistency. Significant assay data can be seen in Table 1. Figure 1 – Plan view of Swell Zone Result with Figures 2 and 3 cross-section reference MF23-213 intersected the Swell Zone approximately 115m west from MF23-207’s 74.4m @ 1.18% Li2O pegmatite intercept. Drill hole MF23-213 provides a high level of confidence in the continuity of the large widths and high grades intersected so far in the Swell Zone while also delineating the trend and geometry of this important new structure towards the West, as shown in figure 2. The Swell Zone trend has a shallow plunge of approximately 10 degrees, trending at 280Az. Page 2 of 17 Figure 2 – Long section of the Swell Zone trend, along the 5518100 northing The Swell Zone remains open towards the west, however current drilling is unable to continue testing the Swell Zone trend at an appropriate angle relative to the pegmatite geometry until submitted permits for new drill pads, located further west and north have been approved, with drill permits expected to be received in the coming weeks. Given the current drill pad limitations for westerly drilling, the focus has turned to assessing and testing the Swell Zone to the east. MF23-214 intersected the Swell Zone approximately 60m east of MF23-207 (Figure 2). This intercept occurs up-dip and provides confidence in the continuity of the Swell Zone. The large width and high-grade results in MF23-207, MF23-213 and MF23-214 confirm the Swell Zone extends over a 200m strike.

The sericite alteration is believed to be localised and, with subsequent drilling designed based on alteration models and the current pegmatite shapes, the Company is very confident in the ability of follow-up drilling to accurately target the Swell Zone mineralisation. Assay results are pending for 15 drill-holes. Current and Future Exploration The Swell Zone remains open laterally to the east and west and continues to demonstrate clear potential for Resource growth at Mavis Lake. Currently drilling continues to delineate the Swell Zone towards the east while simultaneously testing the recently identified pegmatite mineralisation zones beneath the Swell Zone – refer to ASX announcement released 11 September 2023. Further drilling of the Swell Zone will continue both at depth and towards the west once the pending drill permits have been approved. This announcement has been approved for release by the Board of Directors. -endsFor further information please contact Alex Cheeseman Managing Director E: info@criticalresources.com.au P: +61 (8) 9389 4499 Nicholas Read Read Corporate E: nicholas@readcorporate.com.au M: +61(0)419 929 046 ABOUT CRITICAL RESOURCES LIMITED Critical Resources is advancing and developing critical metals projects for a decarbonised future. The Company holds a suite of lithium prospects across Ontario, Canada, including Mavis Lake, Graphic Lake, Plaid and Whiteloon Lake. The Company’s other projects include a copper project in Oman, and a base metals project in Halls Peak NSW, Australia. The Company’s primary focus is the rapid development of its flagship Mavis Lake Lithium Project. Mavis Lake is an advanced exploration project with near-term development potential. The Company completed over 19,500m of drilling in 2022 and has commenced another significant drilling program in 2023. In early 2023, Critical Resources released its maiden JORC Code 2012 Compliant Inferred Mineral Resource Estimate (MRE) for Mavis Lake with 8.0Mt at 1.107% Li2O – making Critical Resources just one of two ASX-listed companies with a JORC Code 2012 compliant mineral resource in Ontario. In parallel, the Company has also commenced initial studies that will underpin the transition from explorer to developer.
