Lithium exploration and project development company Critical Resources Limited ASX:CRR (“Critical Resources” or “the Company”) is pleased to announce that it has received exceptionally high-grade lithium assay results from the recent field program at the Company’s 100%-owned Mavis Lake Lithium Project (“the Project”) in Ontario, Canada. The discovery of surface extensions and new outcrops was announced in late May (refer to ASX announcement, 29 May 2024). The subsequent receipt of assay results from these areas, with lithium oxide concentrations reaching up to 5.12% Li2O, underscores the exceptional potential of the Mavis Lake Project for continued Resource growth and, ultimately, the ability to deliver on the Company’s recently announced JORC compliant Exploration Target of 18 - 29Mt at 0.81.2% Li2O1. 1. Refer Announcement 22 May 2024. The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. Critical Resources Limited ABN 12 145 184 667 ASX:CRR Level 45, 108 St Georges Terrace, Perth WA 6000 P. +61 (8) 9465 1024 W. criticalresources.com.au E. info@criticalresources.com.au High-Grade Extensions at Main Zone East Field crews spent three weeks prospecting across the Mavis Lake Project Area, resulting in the discovery of 31 new LCT-type pegmatites. A total of 83 grab samples were collected to assess lithium mineralisation from spodumene, as well as fractionation and concentrations of Lithium, Rubidium, Caesium and Tantalum. Key results are shown in Table 1 and Figure 1, with full exploration results provided in Appendix 1. Highlights include: • High-grade lithium results ranging from 2.07% to 5.12% Li2O in grab samples across the ~100-metre extensions of spodumene-bearing Pegmatites 7 and 24. • Up to 1.17% Li2O at the ~250-metre extension of spodumene-bearing Pegmatite 20. • Up to 2.76% Li2O in grab samples from Pegmatite 19.

Pegmatite 7 and 24 Extension. Field teams completed prospecting and clearing around Pegmatites 7 and 24 and were able to successfully expose both pegmatites towards the east and west by over a strike length of up to ~100m. Assay results have confirmed high-grade mineralisation, up to 5.12% Li2O from grab samples. Pegmatite 7, trending roughly east-west, is up to 4 metres thick with a known strike length of 100 metres and the mineralisation appears to be open laterally in both directions. Notably, Pegmatite 7 exhibits surface features of megacrystic quartz and spodumene, indicating significant exploration potential (refer to Figure 2 and Figure 3). Page 3 of 18 Figure 2 – Large Coare Spodumene samples from Pegmatite 7 (assays confirm grades up to 5.12% Li2O). The surface contacts of these pegmatites revealed unexpected structural deviations, contrary to previous understanding. Pegmatite 7 exhibited a near-vertical dip, while Pegmatite 24 dips shallowly towards the south, contrasting with the typical shallow northward dip of the Main Zone. This structural divergence is now better understood and the newly defined structural trend of these pegmatites has revealed new drill targets with the potential to host significant high-grade mineralisation close to surface. Page 4 of 18 Figure 3 – Coarse Spodumene at Pegmatite 7 (assays confirm grades up to 5.12% Li2O). Pegmatite 19, 20, and Pegmatite 25 Pegmatite 19 was previously mapped in 2009 and 2018 and was identified then to have spodumene-mineralisation. Field crews were able to replicate similar grades of up to 2.76% Li2O. This pegmatite extends over a known strike length of ~250 metres and is up to 3m wide. Pegmatite 19 is an immediate drill target. The mineralisation of Pegmatite 20 was extended by an additional 250 meters to the north, resulting in a total strike length of approximately 535 meters. Assay results revealed grades of up to 1.17% Li₂O. This extension provides several new high-priority drill targets for further exploration and resource definition. Pegmatite 25 hosted altered out relic spodumene minerals however the alteration remobilized the majority of the lithium values. Even with minimum lithium values, this pegmatite remains a priority for drill testing to determine if the alteration is pervasive throughout the pegmatite or if spodumene minerals occur within this area. Page 5 of 18 Highly Fractioned Pegmatites at Northern Prospects During the field program, a total of 113 muscovite samples were collected from known pegmatites across the Northern Prospects – Gullwing, Coates, Drope, East Drope and Little Wing – with reference samples also taken from the Mavis Lake Main Zone. The samples were collected for internal analysis by Laser Induced Breakdown Spectroscopy (LIBS). LIBS analysis is aimed at determining the degree of fractionation of pegmatites, ultimately to better target potential areas of spodumene mineralisation. A muscovite sample is shown in Figure 4. Figure 4 – Muscovite sample tested for fractionation trend using LIBS analysis The Company utilised LIBS analysis on muscovite samples to determine the fractionation of pegmatites in the following way: • Sample Collection: Muscovite samples were collected from different pegmatite bodies in the field. • Preparation: Samples were cleaned and prepared to ensure accurate LIBS analysis. • LIBS Analysis: A high-energy laser pulse is directed at the muscovite samples. This laser pulse ablates a small amount of the sample, creating a plasma. Page 6 of 18 • Emission Spectroscopy: As the plasma cools, it emits light at characteristic wavelengths. The emitted light is collected and analysed to identify and quantify the elemental composition of the sample. • Data Interpretation: A qualified geologist interprets the spectral data to determine the concentrations of elements such as lithium, rubidium, caesium and tantalum. Higher concentrations of these elements indicate higher degrees of fractionation. • Fractionation Assessment: By comparing the elemental compositions across different samples, the Company can assess the degree of fractionation of the pegmatites. More fractionated pegmatites typically show higher concentrations of incompatible elements. • Geological Implications: The results help in understanding the evolution of the pegmatite bodies and can indicate areas with higher potential for lithium (spodumene) minerals. The data allows Critical Resources to map the spatial distribution of mineralisation, guiding drilling efforts to the most promising areas. The ability to immediately adjust exploration strategies based on LIBS results, combined with the correlation of LIBS data with other geophysical and geological information, reduces exploration risks and validates existing models. Ultimately, this comprehensive, iterative and dynamic approach will optimise drill target selection, increasing the likelihood of a successful spodumene discovery and ensuring that drilling metres are optimised to deliver increased value for money. The results revealed multiple locations with a high degree of fractionation within all pegmatites (refer to Figure 5). Typically, a high-degree fractionation is defined by a K/Rb ratio of less than 20 and lithium concentrations exceeding 500 ppm, however these values are dependent on the overall pegmatite system. Critical Resources will compare the values of known spodumenebearing pegmatite’s muscovite and determine what anomalous values to use.

Future Work These assays will further inform and refine the priorities for upcoming drill testing. Based on current assessments, the Tot pegmatite has emerged as the highest priority for immediate follow-up exploration due to its high-grade and consistent mineralisation. To further delineate the Tot pegmatite, a mechanical stripping and channel sampling program is being designed. This program will aim to expose surface extensions of the outcrop and provide comprehensive channel sample results to support future resource definition drilling. The Company has secured the necessary permits for drilling, stripping and channel sampling to facilitate these efforts. The stripping and channel sampling program at Tot is scheduled to commence in early July 2024. Page 8 of 18 In addition to the Tot pegmatite, extensional drilling to the east and south of the Main Zone, as well as drill testing of the Gullwing Pegmatite, remain priorities. These activities are expected to be part of the Company’s CY2024 drilling program, ensuring a comprehensive approach to exploring and evaluating the mineral potential of the entire project area. This announcement has been approved for release by the Board of Directors. -endsFor further information please contact E: info@criticalresources.com.au P: +61 (8) 9465 1024 ABOUT CRITICAL RESOURCES LIMITED Critical Resources is focused on the exploration, development and delivery of the critical metals required for a decarbonized future, underpinned by a portfolio of lithium projects in Ontario, Canada which are ideally positioned to participate in the rapidly growing North American battery materials supply chain.

In cases where ‘industry standard’ work has been done this would be relatively simple (e.g., ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g., submarine nodules) may warrant disclosure of detailed information.
