Ardea Resources Limited & controlled entities Annual Report 2023 Chairman’s Letter to Shareholders 2023 Dear Shareholders, It is a pleasure to be able to share with you Ardea Resources Limited (Ardea or the Company) 2023 Annual Report. The 2023 financial year has been transformational for the Company as the Ardea Team have delivered on objectives, including the following milestones: 1. 2. 3. The Kalgoorlie Nickel Project (KNP or Project) Mineral Resource Estimate now exceeding 6 Million Tonne Contained Nickel (ASX release 30 June 2023). Completion of the KNP Goongarrie Hub Ore Reserve and Pre-Feasibility Study (PFS) which has defined a +40 Year Operation with Strong Financial Metrics (ASX release 5 July 2023). KNP Goongarrie Hub – Non-binding Memorandum of Understanding (MOU) with Sumitomo Metal Mining, Mitsubishi Corporation, and Mitsui & Co. Ltd (Japanese Consortium or Consortium) which demonstrates the high calibre of the Strategic Partners with whom Ardea has been engaging (ASX release 5 July 2023). The Ardea Team are working closely with the Japanese Consortium to define a scope of work for the Definitive Feasibility Study (DFS) and jointly complete this undertaking, with the Consortium funding the DFS upon the parties agreeing on the DFS scope before the end of the September Quarter 2023. Following the completion of the DFS, Ardea and the Consortium will work towards making a Final Investment Decision (FID) and securing project development funding, with a focus on Australian and foreign Export Credit Agency (ECA) long tenor, low interest rate debt. The Consortium will look to ultimately earn a significant interest in a joint venture which will develop and operate the KNP Goongarrie Hub and will have certain off-take rights. The final binding terms of a proposed joint venture are currently being negotiated between Ardea and the Consortium. The outlook for nickel continues to be incredibly strong with demand growth expected to increase to over 6Mt of contained nickel by 2040. This growth outlook is unprecedented, given that nickel demand was around 2.2Mt in 2020. The strong demand is being driven by traditional uses of nickel in the stainless steel sector and also by the rapidly growing lithium-ion battery sector. The majority of lithium-ion battery (LIB) producers that Ardea has been engaging with are moving towards higher nickel content cathodes to create higher charge density batteries with longer battery life and greater range in electric vehicles. This development is expected to result in even higher demand for nickel, particularly from 2030 onwards. Demand for cobalt to 2030 is forecast to rise by more than 200,000t with the market size more than doubling relative to 2020 to 400,000t according to the Cobalt Institute's Cobalt Market Report. Governments and private investment into Critical Minerals projects via the green energy transition continue to accelerate with the EU Commission noting that the energy transition is set to triple by 2023 from US$1 trillion last year. The US Inflation Reduction Act (IRA) is providing US$500 billion into green energy new spending and tax concessions. This forecast spend will see a greatly increased demand for Critical Minerals. A key feature in favour of the KNP is our location in the Eastern Goldfields of Western Australia, with all KNP tenements located within 150km of the City of Kalgoorlie-Boulder allowing the Company to work with the supportive community and have direct access to key infrastructure, skilled service providers and experienced work force. By completing an equity raise to institutional and sophisticated investors to raise $16,000,000 before costs, the Company is well funded to progress DFS workstreams (ASX release 30 August 2023). All of these factors contribute to the future outlook for Ardea being compelling and I would like to thank all stakeholders for their unwavering belief and support for the Company, as we continue to unlock the full value of our strategic resource base and tenement position. Finally, I would like to thank our dedicated team of employees, directors, and consultants for their hard work which has enabled us to achieve so much and look forward to the next exciting stage of the Company's evolution. Mat Longworth, Chairman Ardea Resources Limited & controlled entities Annual Report 2023 - page 1 Activities Report Environmental, Social and (Corporate) Governance Environmental, Social and (Corporate) Governance (ESG) considerations are at the forefront of Ardea’s operations. Project designs and work practices are based on the Company minimising the project development footprint and CO2 green-house gas emissions when in production. The proposed flowsheet has been enhanced for CO2 mitigation in the neutralisation circuit through introducing an Atmospheric Leach (AL) circuit to assist in neutralising the High Pressure Acid Leach (HPAL) discharge. The AL circuit facilitates upgrade of the site acid plant utilisation and allows Ardea to generate its own site power requirements off-grid, without relying on fossil fuel for power generation. Responsible sourcing of materials, through mechanisms such as mandatory reporting of CO2 footprints for all batteries sold is essential. Traceability is also being implemented with raw materials used in batteries that must be procured according to Organisation for Economic Co-operation and Development (OECD) guidelines for sustainable sourcing. Ardea enjoys strong support from local groups and residents in which we operate, primarily the City of Kalgoorlie-Boulder and the Shire of Menzies as well as nearby First Nations communities. The benign environmental setting, being the Great Western Woodlands, allows excellent post-mining rehabilitation and reafforestation. Ardea’s in-pit tailings disposal strategy, incorporating tailings disposal, waste rock back fill, stockpiled topsoil and finally progressive revegetation, minimises land disturbance and accelerates rehabilitation, concurrent with operations. Critically, at the Goongarrie Hub, mining and processing has no land-use conflict with agricultural activity which occurs in multiple peer nickel laterite centres. During the past year, Ardea has continued to engage with stakeholders who are supportive of the Goongarrie Hub development and is looking forward to the contributions the operation can make to the local community through increased skilled job opportunities, training and enhancing community contributions. In having a West Kalgoorlie Operations Office, Ardea maintains a permanent presence and regular engagement with the local populace within which the Company operates. The Great Western Woodlands environment, within which the KNP is located, allows excellent post-mining rehabilitation and reafforestation. Ardea maintains close relationships with the Department of Mines, Industry Regulation and Safety (DMIRS) and the Department of Biodiversity, Conservation and Attractions (DBCA). Ardea Resources Limited & controlled entities Annual Report 2023 - page 2 Activities Report continued ESG Compliance Internationally accredited Digbee ESG have awarded Ardea an overall ESG rating of “BBB” for both corporate and the Kalgoorlie Nickel Project. For an emergent development company such as Ardea, BBB is a meritorious outcome and an excellent platform to achieve AAA as the Company grows (Figure 1). Figure 1: Digbee ESGTM Assessment Overall Score. Following feedback from Digbee, Ardea is currently working on aspects of its ESG rating that require improvement and will provide Digbee with Ardea’s annual reporting update due for the September Quarter 2023. Ardea envisions a positive improvement to the score attained in 2022. During the year, Life Cycle Assessment (LCA) consultancy and technology company, Minviro, completed a cradle-to-gate LCA of the Goongarrie Hub. Using the KNP Goongarrie Hub’s mass and energy data produced for the 2023 PFS, the expected environmental impacts of Ardea’s nickel and cobalt-containing MHP product have been quantified. The LCA has also undergone third party review and is published in accordance with ISO 14040/2006 and 14044/2006 standards. Minviro reported that the KNP Goongarrie Hub climate change impact is expected to be 11.9kg CO2 eq. per kg nickel in MHP based on Ardea’s Scope 1, 2 and upstream Scope 3 emissions (Figure 2). Ardea’s maiden LCA is deemed relatively low for an HPAL operation primarily due to the use of Mineralised Neutraliser (MN) rather than importing and using nickel- barren calcrete to neutralise acid waste streams. This is also due to the generation of on-site electricity from steam generated as a by-product of burning sulphur within the sulphuric acid plant.

A major requirement for Ardea during the 2023 financial year was to address its obligations under Western Australia’s new Workplace Health and Safety Act 2020 (WHSA) and Regulations which commenced in 2022. An important component of the WHSA is for Ardea to instigate, utilise and comply with the new Mine Safety Management System (MSMS). This MSMS is an overarching framework that brings a mine’s policies, systems, procedures and plans together to help create a safe operation. Ardea has completed this important requirement and is fully compliant. On 30 May 2023 Ardea representatives attended a seminar held by the Association of Mining and Exploration Companies (AMEC) on the changes that occurred during the Work Health and Safety (Mines) Regulations WA 2022 in line with the transitional arrangements now ending and requiring to be in place in the workplace. These changes included the provision of a Mine Safety Management Plan (MSMP) that forms the main requirements for the MSMS. Ardea is also working towards the process of upskilling personnel into required statutory positions (AQF level 5). This will include an examination held by the Department of Mines Industry Regulation and Safety (DMIRS). Clockwise from top left: City of Kalgoorlie-Boulder Electric Vehicle charging station; Part of Ardea exploration field kit; KNP is strategically located close to the City of Kalgoorlie-Boulder; Ardea field support vehicle. Ardea Resources Limited & controlled entities Annual Report 2023 - page 4 Activities Report continued Corporate Objectives Strategy Ardea’s priority is KNP nickel-cobalt laterite project development, commencing with the Goongarrie Hub, as a strategic, long life operation producing battery minerals for the LIB supply chain to further advance the transition to a low carbon future. Development of the Goongarrie Hub will capitalise on the premium goethite ore type and infrastructure-rich location, as highlighted in the recently completed Goongarrie Hub PFS which demonstrated a compelling development opportunity. Once the Goongarrie Hub is in operation, the development of the Kapini and Yerilla Hubs can be considered to unlock further value. Complementary exploration opportunities in nickel sulphides and Critical Minerals within Ardea’s strategic KNP tenement holding will also be pursued, to maximise the value creation from the Company’s internal pipeline of projects. Strategic Partner Process Ardea’s Strategic Partner strategy is linked to DFS and project development funding to enable the KNP Goongarrie Hub to be developed and realise its full potential as a long life (>40 years) source of nickel-cobalt, from the premier resources operating jurisdiction, being the Eastern Goldfields of Western Australia. Ardea is working closely with Sumitomo Metal Mining Co., Ltd, Mitsubishi Corporation, and Mitsui & Co., Ltd, the Consortium (ASX release 5 July 2023), to define a scope of work for the DFS and jointly complete this undertaking, with the Consortium funding the DFS upon the parties agreeing on the DFS scope before the end of the September Quarter 2023. Following the completion of the DFS, Ardea and the Consortium will work towards making a Final Investment Decision and securing project development funding, with a focus on Australian and foreign Export Credit Agency (ECA) long tenor, low interest rate debt. The Consortium will look to ultimately earn a significant interest in a joint venture which will develop and operate the KNP Goongarrie Hub and will have certain off-take rights. The final binding terms of a proposed joint venture are currently being negotiated between Ardea and the Consortium. Ardea and the Consortium have agreed certain exclusivity arrangements, which end before the end of the December Quarter 2023 (unless extended by agreement between Ardea and the Consortium), subject to transaction timelines being met. Under the exclusivity provisions, Ardea may continue discussions with other interested parties that had already commenced due diligence under the Strategic Partner process until the Consortium completes its due diligence, with expected completion before the end of the September Quarter 2023 (unless extended by agreement between Ardea and the Consortium). Multiple potential Partners have been waiting for Ardea to complete the KNP Goongarrie Hub PFS and are now accelerating their due diligence and working with Ardea in trying to secure nickel-cobalt off-take from the KNP Goongarrie Hub. Ardea continues to work with the preferred Partner(s) to refine the scope of work for the DFS, so that the final DFS flowsheet and end-product specifications meet the Partners’ needs. Nickel Market Commentary The market outlook for nickel remains positive and the investment fundamentals continue to strengthen. The Shanghai Futures Exchange is now reportedly accepting class 1 nickel produced from laterite nickel matte and sulphate products. As at late June 2023, nickel LME stocks were around 39,000 tonnes, down from 55,380 tonnes at the start of the year. Ardea Resources Limited & controlled entities Annual Report 2023 - page 5 Activities Report continued Demand for cobalt is forecast to rise by more than 200,000t to 2030 with the market size doubling relative to 2022 to 400,000t according to the Cobalt Institute's Cobalt Market Report. Governments and private investment into Critical Minerals projects via the green energy movement continue to accelerate with the EU Commission noting that the energy transition is set to triple by 2023 from US$1 trillion last year. The US IRA is providing US$500 billion into new spending and tax concessions. This forecast spend will see a greatly increased demand for Critical Minerals. Mineral demand for use in Electric Vehicle (EV) and battery storage is expected to grow at least thirty times to 2040. Battery demand was 353kt Ni in 2022 which was 12% of total nickel demand, but forecast to command 41% of primary demand by 2033 (source: Fastmarkets May 2023). Lithium sees the fastest growth, with demand growing by over 40 times in the Sustainable Development Scenario by 2040, followed by graphite, cobalt and nickel at around 20-25 times (Figure 3). Of note is the scarcity of nickel-cobalt resources compared to other Battery Minerals, such as lithium and graphite. Current producers of nickel will not meet demand forecasts and higher nickel prices will be required to enable new investments to come online. These fundamentals underpin the global significance of the KNP and its international recognition, given the strategic scale of the resource, industry leading low-carbon flowsheet and location in the premium mineral resources operating jurisdiction in the World (Figure 4). With Ardea’s KNP hosting one of the largest nickel-cobalt resources in the developed World, 854Mt at 0.71% Ni and 0.045% Co for 6.1Mt of contained nickel and 386kt of contained cobalt (ASX release 30 June 2023), Ardea is in a prime position to provide essential supplies of sustainably-sourced nickel and cobalt, along with other Critical Minerals (notably scandium).

Resources from the Goongarrie, Highway and Siberia North laterite nickel-cobalt deposits are planned to be the base load feed for a process operation located at Goongarrie South. resources at Goongarrie are The dominantly the premium goethite style and extend continuously over 25km of strike and at Highway, 30km north, over a length of 6km. All continuous strike Goongarrie Hub mineral resources are located on granted mining leases with Native Title Agreements in place and tenure 100%-controlled by Ardea. The Project also has ready access to high- quality infrastructure with the Goldfields Highway, rail line and power infrastructure passing through the project area (Figure 6). The gas pipeline is located some 25km to the east and there are three port options, these being Esperance, Fremantle and Kwinana, that are well serviced by the KNP road and rail network. Significantly, the KNP is located on the rail connection to the developing battery hub at industrial area the Port of Kwinana immediately south of Perth, as well as east to Port Augusta and developing low-carbon energy hubs on the eastern Australia seaboard. Figure 5: KNP location plan. Projection GDA94 Zone 51. Ardea is actively engaged with Commonwealth and State agencies and statutory authorities who are coordinating the push for a downstream battery industry within Australia through “Team Australia” and the State of Western Australia through “Team WA”. All the LIB feedstocks, including nickel and cobalt, are available in Australia, and WA in particular, at the scales required for World-significant green energy centres of excellence. Ardea Resources Limited & controlled entities Annual Report 2023 - page 7 Activities Report continued Figure 6: Aerial image of Ardea’s KNP Goongarrie Hub at Goongarrie South looking south towards Kalgoorlie- Boulder showing road and rail infrastructure within the granted mining leases upon which the resources are located. Note the semi- arid woodlands environment, ideal for project development, safe tailings management and revegetation post mining. Project Funding The KNP Goongarrie Hub technical and economic fundamentals provide a strong platform for Ardea to source traditional financing through debt and equity markets, in addition to pursuing other financing strategies should this be to the benefit of Shareholders. Whilst no formal funding discussions have commenced, the Company has engaged with multiple financial institutions, including Export Credit Agencies from Australia and abroad, and these financial institutions have expressed a high level of future interest in being involved in funding the KNP Goongarrie Hub. Typical project development financing would involve a combination of debt and equity. Initial indications from financiers are that the debt component of the funding requirement would be significantly greater than the equity funding requirement. The Company is running a Strategic Partner process to select a preferred partner or consortium of partners to provide input into the DFS scope of work, fund this undertaking and also to work with Ardea on securing future project development funding. Now that Ardea have concluded the KNP Goongarrie Hub PFS, interest in this process is at an all-time high, as -take. Project off-take rights will only be awarded to multiple companies express strong interest in securing nickel-cobalt o selected Strategic Partner(s) that commit to making a substantial equity investment in the KNP Goongarrie Hub Project. ff Ardea Resources Limited & controlled entities Annual Report 2023 - page 8 Activities Report continued Feasibility Programs Ardea’s focus remains on development of the KNP Goongarrie Hub. On 5 July 2023 ASX Release ‘KNP Goongarrie Hub Ore Reserve and Feasibility Study Defines +40 Year Operation with Strong Financial Metrics’ provided multiple PFS Highlights, including: • • • • • • • • Ore Reserve – 194.1Mt at 0.70% Ni and 0.05% Co for 1.36Mt of contained nickel and 99,000t of contained cobalt1 Mining optimisation studies have projected production of approximately 30,000t of nickel and 2,000t of cobalt per year for more than 40 years. Year 1 to 5 (post ramp up) production >34ktpa nickel and >3ktpa cobalt1 Conventional low-cost open pit mining methods result in mining costs comprising less than 12% of total operating cost with a very low strip ratio at an average of 1.5 for the first 35 years of mine life1 The project generates2: o o o o Pre-tax NPV7 of A$7,625M and IRR of 30% Post-tax NPV7 of A$4,980M and IRR of 23% Average Annual EBITA of A$800M Project pay back within 3.1 years Direct cash cost after Co by-products of US$3,763/t Ni in MHP during the first five years of operation, and US$5,763/t Ni in MHP over life of mine 2 Total capital cost of A$3,117M, including process plant and infrastructure cost of A$2,264M and sulphuric acid, steam, and power plant cost of $574M 2 LCA is expected to be 11.9 kg CO2 equivalent per kg nickel in MHP based on Ardea’s Scope 1, 2 and upstream Scope 3 emissions3 In-pit tailings disposal minimises environmental footprint and enables mine site rehabilitation, concurrent with steady- state mine operation. The PFS developed the engineering and design definition for the KNP Goongarrie Hub to an expected accuracy of +/-25%. The base case design features two x 1.5Mtpa Goethite HPAL autoclaves. Acid, heat and energy balance is facilitated with the AL circuit with 0.3Mtpa Mineralised Neutraliser Fines, 0.15Mtpa Grind AL and 0.05Mtpa Bene AL feed. The KNP flowsheet follows a proven hydrometallurgical route for treating nickel and/or cobalt laterite ore. It produces mixed nickel-cobalt hydroxide precipitate (MHP) filter cake, from goethite and minor saprolite ores. The process flow diagram is represented in Figure 7. Ardea’s project management philosophy in planning for the next KNP Goongarrie Hub project phases recognises the need for the necessary groundwork ahead of project execution, with examples of the philosophy planned to be adopted including: • • • • Staged study and delivery strategy. A high level of engineering targeted in the DFS. Engagement of key equipment package vendors during the DFS to provide initial engineering and input to the DFS. The design and construction of supporting infrastructure prior to the main process plant construction. 1 2 3 See Section 5 of the 5 July 2023 PFS release for detailed Ore Reserve table and Appendix 1. See Section 14 of the 5 July 2023 PFS release for detailed notes on the financial metrics which include inputs of US$25,000/t nickel price, US$60,000/t cobalt price and exchange rate of 0.67 AUD:USD. Direct cash cost excludes royalties and includes third party freight charges and cobalt credit.

Ardea Resources Limited & controlled entities Annual Report 2023 - page 10 Activities Report continued Resource Modelling The Total Mineral Resource inventory for the KNP has been updated to reflect the most recent resource estimates available for all of Ardea’s nickel laterite deposits and was released to the ASX during the year (‘Kalgoorlie Nickel Project Mineral Resource Estimate Exceeds 6 Million Tonne Contained Nickel’, 30 June 2023). The main purpose of this update was to classify the MN as part of the Mineral Resource Estimate (MRE), to allow this material to be included in the Ore Reserve. As part of the PFS, the Goongarrie Hub MRE was re-evaluated to consider the MN that is captured within optimised open pits, with a grade of less than the 0.5% nickel MRE reporting grade. Once this material has been screened, the coarse magnesium-rich magnesite saprock has been demonstrated to be a viable source of neutraliser and the fine goethite and magnesian clay-rich fraction a viable source of AL feed (Ardea ASX releases 16 November 2022 and 15 June 2023). This extra neutralising material contributes additional project value through its magnesite component being used in the leaching circuit for acid neutralisation, to which it adds nickel-cobalt units at nil extra cost. Additionally, the MN Fines component contribute to the nickel-cobalt production as the dominant feed for the AL circuit. The current PFS optimisation is based on two 1.5Mtpa HPAL autoclaves, along with 0.5Mtpa AL plant feed. The majority of the AL feed will be generated from MN Fines, so pit designs are now essentially agnostic to AL Material Type requirements. The PFS assumes a feed allocation ranking approximately as follows: 69% Grind/HPAL; 17% Beneficiation/HPAL; 8% MN Fines (to Grind/AL circuit); 4% Grind/AL and 2% Beneficiation/AL (which being volumetrically minor can be blended with Beneficiation/HPAL circuit). The MN is the largest source of nickel units to the AL Pregnant Liquor Solution (PLS). The PFS identified that the quantity of MN required for neutralisation could not be supplied using the 0.5% Ni cut-off used for estimating the Goongarrie Hub MRE. Therefore, it was necessary to consider lower grade material to meet supply requirements. Key specifications for the MN were: • • Loss on ignition (LOI) >25% and Ni >0.3%, or LOI >25% and Ni >0.2% and Si <= 23% As this specification was based on the characteristics of the material that demonstrated acid neutralising capacity and not nickel economics, each deposit contained surplus requirements. The preferred source of MN was defined as a subset of this Material Type using pit optimisation and scheduling analysis undertaken as part of the PFS. Compared to traditional nickel laterite operations that transport limestone from the Nullarbor Plains or from Esperance lime sands, the MN cost per tonne benefits have a significant influence on pit optimisations, such that pits may be driven deeper in order to access the saprock MN. A detailed summary of the MN captured in optimised open pits, with a grade of less than the 0.5% Ni, is provided in the section below in Table 1. These estimates represent only the MN within lower grade material and are not included in the Mineral Resources inventory reported at greater than 0.5% Ni cut-off grade, which is shown in Table 2 and Table 3. Only the deposits in the Goongarrie Hub considered in the PFS, referred to as the PFS subset are included in the MN tables below. Other Goongarrie Hub deposits (Ghost Rocks, Siberia South and Black Range), the Kalpini Hub deposits, the Yerilla Hub deposits and Bulong deposits have not been included. Results are based on previously reported resource models at Goongarrie Hub (Ardea ASX releases 15 February and 16 June 2021).

All the resources are constrained within optimised “blue sky” pit shells using appropriate nickel and cobalt prices, mining and processing costs and pit slope parameters to determine the material that could potentially be economically mined in the future. The Mineral Resource has been estimated and reported in accordance with the guidelines of the 2012 edition of the Australia Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves the JORC Code (2012). All the Mineral Resource estimates completed prior to the introduction of the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code 2012) have been reviewed by Ardea Competent Persons and confirmed to comply with JORC Code (2012) guidelines. In 2009 Snowden Mining Industry Consultants (Snowden) completed a resource model for Siberia North utilising Ordinary Kriging (OK), followed by Uniform Conditioning (UC). Previously reported MRE tables have included the OK estimates for Siberia North, while the other five deposits at the Goongarrie Hub all utilise OK followed by Local Uniform Conditioning (LUC) for estimation and are reported as LUC estimates (Table 3). LUC for nickel laterite is considered to provide the most detailed and appropriate model for open pit mining, including dilution, for the Goongarrie Hub deposits. The UC model at SN was the closest to this in terms of methodology and block size, so was deemed the most appropriate and consistent interim fit. As such, the Total MRE has been updated to reflect the change to UC for Siberia North.

The sum of individual amounts may not equal due to rounding. This Ore Reserve estimate is for a subset of the KNP Goongarrie Hub deposits being Goongarrie South, Big Four / Scotia Dam, Goongarrie Hill, Highway and Siberia North. Ardea Resources Limited & controlled entities Annual Report 2023 - page 15 Activities Report continued Mining optimisation studies completed, as part of the PFS have defined production of approximately 30,000t of nickel and 2,000t of cobalt per annum for more than 40 years. This projection comprises the Ore Reserve and the inclusion of a small amount of Inferred Mineral Resource (20Mt or 9% of total MRE) spread over the Life of Mine. Enhancing previous studies, the updated mine plan uses a selective mining approach to maximise economic extraction of the KNP Goongarrie Hub mineral resource by defining ore types to leverage the variability of the mineralisation. This was achieved by maximising higher value ore streams through the HPAL circuit and diverting to the AL circuit lower value streams that would otherwise be stockpiled for end of project processing. Processing Research and Development The Ardea FY2023 Research & Development (R&D) is based upon metallurgical experiments aimed at optimising the plant performance, product range and hence revenue streams from the KNP and its Goongarrie Hub. CSIRO and ARC Ardea continues to work with industry leading research partners, such as Australia’s national science agency CSIRO, and the Australian Research Council (ARC). Ardea actively engages with the CSIRO specifically on the Indicator Minerals for Nickel Sulphide Exploration project, including assessing samples provided from the Kalpini, Goongarrie and Highway projects. The potential for the KNP Walter Williams Formation (WWF) to host magmatic nickel sulphides will be tested in Q3 CY2023 with a diamond drill hole and down-hole EM survey. Ardea is the largest holder of the WWF in the Eastern Goldfields, as this is the dominant unit that has weathered to form the Goongarrie Hub nickel laterite deposits. Ardea has also been actively engaged with ARC, and is a sponsor of the ARC Training Centre in Critical Resources for the Future. Ardea expect the outcomes from the Training Centre to have industry-wide benefits regarding the future of Critical Minerals exploration and extraction leading towards an ESG supply in the future, and for training the next generation of geoscientists in this field. Future Battery Industries – Cooperative Research Centre (FBICRC) The FBICRC is an independent centre where industry, government and researchers can come together to create the tools, technologies, and skills to grow the role of battery storage in Australia’s electricity grids and make Australia a larger downstream player in global battery value chains. The focus of all Ardea R&D is ultimately aligned with the FBICRC objective of developing Australian autonomous, ESG- compliant, renewable energy supply chains. Ardea sponsors and works with the FBICRC team on multiple work streams. Each one of these work streams is aimed at ensuring quality product specifications and ESG compliance for the Australian LIB sector and sustainable and ethical supply from the best-regarded operating jurisdiction in the World, being Western Australia. Ardea has assembled suitable bulk drill sample material from current Goongarrie Hub drilling plus product from the 2018 PFS Goongarrie pilot run as test material for the planned FBICRC pilot plant. Mineralised Neutraliser The key KNP R&D processing break through achieved during 2023 was filing an International PCT Patent Application entitled “Acid Neutraliser Composition” on 13 June 2023 at the World Intellectual Property Office (WIPO). The international application, PCT/AU2023/050520, covers Ardea’s MN R&D which extends from the earlier Australian Provisional Patent Application filed at IP Australia on 11 November 2022 (see ASX releases of 16 November 2022 and 15 June 2023). The filing of this International PCT Patent Application at WIPO gives Ardea the option to pursue patent protection for its MN in over 150 countries, including Australia, and represents a significant step towards gaining patent protection in countries around the World for this major flowsheet enhancement. Ardea Resources Limited & controlled entities Annual Report 2023 - page 16 Activities Report continued Impetus for the MN experiments was to test whether magnesite could replace the calcitic limestone invariably used for Eastern Goldfields nickel laterite sulphuric acid neutralisation and in so doing save on consumable purchase and transport cost and minimise CO2 emissions associated with transporting the limestone to site. Scandium and Rare Earth Elements Key experiments relate to sustainability enhancements for the KNP HPAL and AL flowsheets. In terms of potential by- product revenue streams, opportunities involving the Critical Minerals cobalt, scandium, the Platinum Group Elements (PGE) - Ru, Rh, Os (due to excessive assay cost, using 500ppb Pt-Pd as a pathfinder in pulp re-assay) and the rare earth elements (REE) neodymium, praseodymium, terbium and dysprosium, used in magnets for EV motors and wind-turbine generators. Highly sought Critical Minerals documented within the KNP lateritic enrichment regolith profile include: • • • • • Nickel-cobalt-manganese (NCM) content in LIB including precursor cathode-active material; EV electric motor REE permanent NdFeB magnet metals, most notably Nd-Pr-Tb-Dy. The KNP also has common Ce and La; Scandium for scandium-aluminium lightweight, high-strength fabrication in general and EV chassis in particular; Vanadium for community-scale and larger solid state batteries; Critical Minerals targets at potentially extractable grades identified during KNP R&D include: o o o Gallium (Ga). Ba, Cr, In, Mg, Mo, Te, Ti, Sn, W, Y, Zr; and PGEs - Ru, Rh, Os. All these Critical Minerals can be realistically assessed for recovery because the HPAL process requires complete dissolution of goethite-hosted nickel-cobalt mineralisation, thereby rendering all contained metals into solution and thus amenable to recovery. This does not require each of these metals to individually be in stand-alone economic concentrations. Recovery of these metals relies on nickel and cobalt hydrometallurgical recovery, potentially providing significant credits and upside to the project economics. Metallurgical test work with a consultant desk-top study into the viability of recovering co-product Critical Minerals from the HPAL PLS, focussed initially on scandium. Critical Minerals research and development is predicated on the 60 element Ardea multi-element assay suite used in all sampling programs. The R&D focus for the Company continues to be searching the KNP technical data base to select archived Ardea drilling sample pulps for re-assay for Critical Minerals (notably REE co-products and identifying fertile nickel sulphide multi-element ratios indicative of PGEs). The PGE R&D is a joint CSIRO- Ardea program. A CSIRO-Ardea conceptual nickel sulphide target at Highway has secured WA State Government Exploration Incentive Scheme (EIS) support and core hole commenced. As well as quantifying nickel sulphide prospectivity, a distinctive suite of felsic to intermediate intrusive-hosted regolith mineralisation will be researched. Ardea’s extensive and strategic land holding in the Eastern Goldfields of WA comprises over 170 tenements, covering over 4,100km2 and in addition to the globally significant nickel-cobalt-scandium KNP resource, is highly prospective for nickel sulphides and Critical Minerals (Figure 5). Bench-scale Metallurgy ALS conducted test work on samples from the Highway deposit, finding that ore scrubbing was necessary for good metal recoveries, and that gravity separation of the +200 micron fraction did not yield a viable by-product stream. Proof of concept for the HPAL and AL circuits was confirmed, and the in-pit neutraliser obtained acceptable Acid Neutralisation Capacity (ANC) performance. Final ANC results (at a final free acid of 20 g/L) gave an ANC value of 797 kg H2SO4/t. In the same process, the neutraliser also delivered good nickel and cobalt credits. Metal extractions from the Mineralised Neutraliser scats under simulated process conditions were 86.5% and 75.3% respectively. The patent application was submitted on this basis. Ardea Resources Limited & controlled entities Annual Report 2023 - page 17 Activities Report continued Laboratory batch calcination tests were conducted on Ardea magnesite samples. A simple citric acid reactivity (CAR) test demonstrated that the calcine was not suitable for chemical-grade metallurgical purposes, but remains suited to neutralisation. Potential improvements to Secondary Neutralisation (SN) chemistry were identified through the use of oxidised manganese residues for ferrous iron oxidation. This was scoped for testing at the DFS stage. Sterilisation drilling from the planned process plant site and accommodation village site was completed in Q1 2023. Analytical results returned anomalously high concentrations of REEs and a bulk sample was subject to metallurgical test work to examine the feasibility of REE recovery. The research is low priority compared to the nickel-cobalt studies. To further develop the main flowsheet, a scope of work for bench-scale test work was provided to local metallurgical laboratory IMO (Metallurgy Pty Ltd.). This scope was intended to provide supporting data for the DFS design phase, and concentrated on the hydrometallurgical process, especially around the AL and some novel opportunities for improving the solution purification chemistry efficiency (alternative ferrous iron oxidation process, MHP washing efficiency, Scavenger precipitation residue oxidation). Data from the 2005-2009 Vale Inco PFS ore preparation test work was consolidated and reviewed for further interrogation. A study of alternatives for increasing HPAL productivity was conducted. Options are to increase the ore grade, increase the slurry density or to reduce the autoclave residence time. Options for increasing HPAL autoclave productivity were identified and test work scopes for evaluating these options have been submitted for quotation. These options are to be evaluated in the upcoming metallurgical bench testing program Flowsheet Development Thermal desalination of local bore water using low grade waste heat from the acid plant was selected for desalinated water supply. Initial design values for AL metal extractions were determined after a review of 2023 ALS bench-scale test work, and used in the PFS mine production model. The design criteria value for the HPAL autoclave residence time used in the PFS was 70 minutes. Post PFS a more detailed review of test work and peer project operating data has indicated that 60 minutes is more appropriate. This factor will be used in future DFS mass balance and production projections, subject to ongoing test work. Replacing imported limestone / lime sand and neutraliser with in-pit Mineralised Neutraliser was adopted. This initiative reduces the logistical and reagent costs, while increasing the nickel and cobalt production rates. A third party review of scandium and REE processing technology was conducted. It was concluded that the resource was amenable to scandium recovery and may be included in a future flowsheet. This would be an add-on to the nickel-cobalt flowsheet, and needs to be evaluated in future studies. The REE content of the reviewed material was not suited to assessment. Intellectual Property As previously announced, Ardea lodged patent applications in Australia (AU2022903389) 11 November 2022, and with the WIPO on 13 June 2023. PCT/AU2023/050520 is related to the use of Mineralised Neutraliser in the Ardea process. This intellectual property was developed during investigations into the mineralogical and hydrometallurgical properties of a previously unutilised portion of the lateritic horizon, and enables Ardea to extend the value of the resource and reduce the economic and environmental costs of providing the neutraliser reagent to the flowsheet. Materials of Construction A study reported on the feasibility of using alternative materials for severe service applications. Studies continue. Ardea Resources Limited & controlled entities Annual Report 2023 - page 18 Activities Report continued Hydrogeology At KNP Goongarrie Hub, all nickel-cobalt-scandium mineral resources are located on granted mining leases. As such, Ardea has first rights to any ground water underlying these areas. Past work by Ardea has defined multiple water sources, with water for project development to be sourced from dedicated bore fields. Potential sources of groundwater for the KNP include alluvial sand and gravel deposited in the base of deeply-incised palaeovalleys (“palaeochannels”), the siliceous and vuggy weathering products of ultramafic rocks (“cap-rock”) forming the nickel laterite ore, and fractured mafic bedrock Water exploration drilling during the year included 42 holes for 2,579m testing targets at Siberia North, Siberia South, Goongarrie South, Black Range and Papertalk. This drilling identified a resource of fresh to saline groundwater. Passive seismic surveys were completed in two campaigns in December 2022 and March-April 2023 at several locations in and around the Goongarrie Hub largely in search for palaeovalley aquifers. Results were of high quality and delineated multiple Tertiary palaeochannel targets for potential future testing. The hydrogeology section of the PFS incorporated all results from recent water exploration programs. Three groundwater streams are needed for the KNP: a Raw Water Stream (1.6 GL/a at <70,000 mg/L), which will be treated using thermal desalination primarily for use in the autoclaves; a Process Water Stream (3.1 GL/a at <100,000 mg/L) to be treated by nanofiltration and is primarily for ore preparation; and Camp Water Supply (0.3 GL/a at <40,000 mg/L) for mine construction and camp supply which will be treated using reverse osmosis. As part of the PFS a base case supply option was defined to meet these water demands. Ardea has two water abstraction licences granted over the central Goongarrie Hub and multiple search for water miscellaneous licences granted to provide sufficient long term optionality to source water requirements for future production. Ardea will continue the water supply reviews at the concept level stage to find the best water supply options and then undertake more detailed engineering and cost estimates in the planned DFS. Further exploration drilling and seismic surveys will continue including on the multiple regional palaeovalley targets, as well as, dewater studies around planned pit sites.

Ardea Resources Limited & controlled entities Annual Report 2023 - page 19 Activities Report continued Infrastructure and Logistics The KNP has access to high-quality infrastructure with the Goldfields Highway, rail line and power infrastructure passing through the project area and the Goldfields Gas Pipeline within 25km. The plant site is planned to be directly located to the southeast of the Pamela Jean pit, which minimises the tramming distance to the process plant during the critical early mining phase. Site sterilisation drilling was conducted over the proposed plant site and the anticipated location of the construction village. This work also provided preliminary geotechnical information, indicated that supporting bedrock lay within 7m of the surface for most of the planned process plant area. The site topography is relatively flat thus minimising earthworks. The manning strategy includes a Kalgoorlie-Boulder office and logistics base, enabling significant pre-assembly in construction, with those personnel not required to be permanently based at site able to make day trips on an as-needs basis. Ardea and the City of Kalgoorlie-Boulder (CKB) liaise regularly on key project development updates, community and accommodation developments. Further CKB continues to support Ardea with hosting Strategic Partner site visits. Logistics provider QUBE completed a high-level scoping study which provided an initial supply chain model of a mine to port solution for the export/import of MHP, magnesia, sulphur and lime that formed the basis for the PFS. This study identified three potential ports (Kwinana, Fremantle or Esperance ports) to import sulphur, bulk lime, magnesia and other reagents and two potential ports (Esperance and Fremantle) for the export of MHP using 20-foot general purpose containers. Haulage options reviewed road trains and rail options and combinations between the port and site. A desktop study identified a viable construction-phase delivery route for the HPAL autoclaves and similar heavy equipment. The overall route from Esperance Port to Goongarrie appears relatively simple. Environment and Rehabilitation All project development within the KNP is aimed at including systematic and rapid rehabilitation concurrent with operations. The KNP is located within the Great Western Woodlands, the largest and healthiest temperate to semi-arid (Mediterranean climate) woodland on Earth. The woodlands cover almost 16,000,000 hectares from the Nullarbor Plain in the east to the Wheatbelt in the west; from Esperance in the south through to the inland mulga country north of Kalgoorlie, including the KNP as a comparative very small component (Figure 5). Due to the 2023 expanded development footprint of the Goongarrie Hub which also reflects Ardea’s current flowsheet, baseline surveys completed in 2018 have been extended and include further surveys to incorporate the latest environmental standards and guidelines. While the Autumn fauna, flora and vegetation surveys have been completed, in addition to the Baseline Ecological Study (rewetting trials) of Lake Goongarrie, Lake Owen North and peripheral wetlands, further baseline surveys will be completed over the 2024 financial year. Ardea’s lead environmental consultant continues to manage all baseline surveys and provides advice and guidance to Ardea for all other baseline studies which are planned to be finalised in early to mid-2024 for subsequent referral to the Environmental Protection Authority. Mine rehabilitation methodology is facilitated through four decades of WA open pit gold mine operations, and the KNP footprint is minimised using mining voids for tailings and mullock disposal. Mining voids will be progressively rehabilitated during operations and returned to their pre mining state, by dressing the back filled open pit voids with topsoil (Figure 8) and then revegetating. In terms of ESG compliance for hydrometallurgical metal processing, the KNP’s benign and manageable environmental footprint contrasts strongly with “wet tropical laterite” projects. The tropical laterites require submarine tailings disposal or valley tailings storage with consequent substantial environmental risk. Tailings disposal in these environments tends to be further complicated by high rainfall and the fact that most tropical laterite deposits are in seismically active regions. Additionally, wet tropical laterite production areas commonly involve non-restorable rain forest habitat destruction. Ardea Resources Limited & controlled entities Annual Report 2023 - page 20 Activities Report continued It is doubtful whether wet tropical laterite hydrometallurgical battery metal sources can comply with the ESG standards required by the Japanese, South Korean, European and North American EV sectors, particularly where submarine tailings disposal is used. Similarly, with more than 3,000mm of annual rainfall in the tropical laterites, it is an immense challenge for long-term tailings stabilisation. The KNP semi-arid climate with robust environmental setting is likely just as important as the premium goethite, high nickel grade and excellent ore rheology for its economic attractiveness. A third party review of tailings storage options and present industry practice was received. It was concluded that in-pit tailings storage provided significant environmental and economic benefits compared to above-ground tailings. Forced evaporation of excess water from the tailings decant water was identified as an alternative to evaporation ponds. A consultant proposal showed a significant capital cost saving, with the bonus of reduced environmental footprint. Rehabilitation of exploration sites at Ardea’s Kalpini, Bulong and Siberia South projects was completed.

Ardea Resources Limited & controlled entities Annual Report 2023 - page 21 Activities Report continued WA Nickel Sulphides and Critical Minerals Ardea’s extensive and strategic land holding in the Eastern Goldfields of WA comprises over 170 tenements, covering over 4,100km2 and in addition to the globally significant nickel-cobalt-scandium KNP resource, is highly prospective for nickel sulphides and Critical Minerals (Figure 9). Ardea Nickel Sulphide Strategy Ardea’s nickel sulphide exploration strategy complements the development of the KNP. The KNP nickel sulphide targets are an asset in a region of multiple nickel sulphide concentrators, with most constrained by insufficient sulphide feed availability. Nickel sulphide also has potential value for a nickel laterite operation, in that it is a potential addition to any goethite autoclave feed for exothermic heating (optimise steam use), Eh reduction to control hexavalent chromium and adding nickel and sulphur units to the autoclave reaction vessel, and typically improving overall nickel recoveries. An additional bonus is that metal concentrations considered deleterious to conventional nickel sulphide flotation concentrator processing do not affect the HPAL process, opening the possibility of mineral extraction from nickel sulphide deposits that may otherwise be overlooked. Figure 9: Ardea tenement plan highlighting the location of the Kalpini Project, Emu Lake Nickel Sulphide Camp with nickel mines and occurrences in the region. Projection MGA 94 Zone 51. Ardea Resources Limited & controlled entities Annual Report 2023 - page 22 Activities Report continued Kalpini Nickel Sulphide Project Ardea’s Kalpini Project is located 70km northeast of the City of Kalgoorlie-Boulder and covers 121km2 of contiguous granted tenure 100%-owned by Ardea (Figure 9 and Figure 10). The Type 1 massive nickel-copper-PGE sulphides discovered at the Binti Prospect at Emu Lake occur in the Kurnalpi Terrane which is significant given there are only a few other Type 1 nickel sulphide occurrences in this Terrane. Ardea hold approximately 25km strike of the prospective Western Komatiite Belt that is largely unexplored and highly prospective for primary magmatic nickel sulphide mineralisation. Regionally there are two distinct Kalpini ultramafic units each with 20-25km strike within Ardea tenure (Figure 10): • • The Kalpini Eastern Komatiite Belt hosts the Wellington East and Acra North nickel laterite deposits containing 75Mt at 0.73% nickel and 0.04% cobalt, for 549.7kt nickel and 32.6kt cobalt (Ardea ASX release 30 June 2023). The ultramafics are typical of the Walter Williams Formation style consisting of a thick 200-600m sheet with olivine orthocumulate upper and lower contacts and core olivine meso-adcumulate (Dunitic Sheet Flows-Layered Lava Lakes) which weathers to nickel laterite. The Kalpini Western Komatiite Belt hosts the Binti nickel sulphide mineralisation. There are at least two fertile nickel sulphide ultramafic flows at Emu Lake being the Western Ultramafic (WU) and Central Ultramafic (CU). The volcanics are characterised by a bi-modal co-magmatic suite, with each cycle having a footwall dacite volcanic overlain by ultramafic volcanic flows. The ultramafics are orthocumulate flows typically 10-40m thick, with massive, matrix, blebby and disseminated nickel sulphides identified in the WU and CU. The 2021-2022 drill testing of the Western Ultramafic at Binti discovered significant komatiite-hosted massive Ni-Cu-PGE sulphides i.e. AELD0003: 2.72m at 5.42% Ni and 0.85% Cu from 391.04m including 1.23m at 8.22% Ni and 0.56% Cu from 391.04m (Ardea ASX releases 3 December 2021 and 14 January 2022). Ardea completed four diamond drill holes for 2,368.5m during the September Quarter 2022, including DHEM surveys on all holes, with three of the diamond holes (AELD0007 - AELD0009) drilled at the Binti prospect (Figure 11). Every drill hole intersected nickel sulphide mineralisation and demonstrated the potential for both high grade massive nickel sulphides and disseminated nickel sulphides: • • • AELD0007: targeted a 100m x 60m off-hole DHEM plate near the basal contact of the Western Ultramafic. The drill hole intersected 0.46m @ 3.09% Ni, 0.49% Cu and 0.65g/t PGE (Pt+Pd) from 491.69m and three zones of disseminated nickel sulphides with the best 4m @ 0.63% Ni from 510m AELD0008: targeted a 280m area with minimal previous drilling between Binti South and Binti Central (Figure 11). The drill hole intersected nickel sulphides in the Central Ultramafic (0.2m @ 1.31% Ni from 371.29m and 2m @ 0.47% Ni from 383m) and blebby-matrix/breccia sulphides in the Western Ultramafic (5.83m @ 0.6% Ni from 508.17m including 0.55m @ 2.05% Ni, 0.23% Cu and 0.57g/t PGE (Pt+Pd) from 511.86m). This drill hole detected a new off- hole conductor (82m x 50m; 5,000 siemens) mostly below and north of the hole (Figure 11) AELD0009: targeted a 30m x 30m off-hole DHEM plate above and south of AELD0004 (Figure 11). The drill hole intersected nickel sulphides in the Central Ultramafic (10m @ 0.47% Ni from 326m) and the Western Ultramafic (3.19m @ 0.62% Ni from 448m) At the Binti Prospect 3D modelling indicated the ‘hottest’ ultramafic flows are at Binti Central at depth. The current interpretation is that the massive sulphide mineralisation at the Binti Prospect may be defined by tight folding around primary lava pathways, with mineralisation on or close to primary basal contact positions. These mineralised lava pathway positions are currently interpreted as moderate to steeply south plunging and are open both up and down plunge (Figure 11). Previous nickel sulphide intersections at the Binti Gossan prospect occur in the Central Ultramafic, whereas thicker intersections at Binti Central and Binti South occur in the Western Ultramafic which is absent at the Binti Gossan. A diamond drill program comprising six holes for 3,210m was planned mostly in the Binti area (Figure 11) which could be executed once current Goongarrie Hub feasibility programs are completed. Ardea Resources Limited & controlled entities Annual Report 2023 - page 23 Activities Report continued An additional hole AELD0010 was drilled targeting a regional magnetic anomaly 6km southeast of the Binti prospect where previous drilling identified broad zones with >100ppb Pd and >200ppm Cu (up to 1,070ppm Cu) in ultramafics. AELD0010 intersected very thick ultramafic stratigraphy (578m in total, open at end of hole) and while assay results showed no obvious nickel sulphide mineralisation there was >50ppb Pt+Pd from 119-125m, 132-138m and 232-242m, the latter two intersections with fine disseminated sulphides. There was no priority DHEM plates associated with AELD0010. During FY23 regional technical targeting using detailed geochemical ratios, geophysical data, geological and structural interpretation was completed, which generated twelve nickel sulphide exploration targets in the ~20km strike Western Komatiite sequence (Figure 10). An RC drill program was designed with 52 RC holes for 11,200m, which could be executed once current Goongarrie Hub feasibility programs are completed. Figure 10: The Kalpini Project showing interpreted geology and Komatiite Belts. The historic nickel laterite resources are located on the Eastern Komatiite Belt, with the Western Belt highly prospective for nickel sulphide mineralisation.

AELD0003: 2.72m at 5.42% Ni and 0.85% Cu from 391.04m including 1.23m at 8.22% Ni and 0.56% Cu from 391.04m (ARL ASX 14 Jan 2022). Ardea Resources Limited & controlled entities Annual Report 2023 - page 25 Activities Report continued An aircore program of twenty-four vertical holes for 1,077m was completed on E27/524 in the December Quarter 2022. The program was designed along three traverse lines with 80m centres (Figure 12) to infill previous laterite drilling and as a first pass assessment of nickel sulphide potential. Assay results returned significant nickel sulphide anomalism in AELA0022: 14m @ 0.52% Ni, 231ppm Cu and 129ppb Pt+Pd from 24m including 4m @ 0.62% Ni, 310ppm Cu and 177ppb Pt+Pd from 32m (Figure 12; ASX Release 2 May 2023). Textures including presence of distinctive weathered pits in the drill chips indicate weathered nickel sulphide mineralisation in saprock ultramafic. The intersection is close to eastern basal contact of the interpreted Western Ultramafic 1km south-southeast of Binti South (Figure 12). The combination of the anomalous geochemistry, flank of magnetic anomaly, the stratigraphic interpretation and absence of surface EM in this area make this a compelling nickel sulphide target to follow up with the planned regional RC drill program. Regional mapping and rock chip sampling at Kalpini has continued. Significant outcrop was identified in M28/205 with a similar stratigraphic sequence interpreted as at the Binti prospect ~10km to the north (Figure 10). This indicates the geology is likely consistent across this section of the belt and gives greater confidence that potential mineralised nickel sulphide channels exist within the entire Western Komatiite Belt.

Ardea Resources Limited & controlled entities Annual Report 2023 - page 26 Activities Report continued Lithium Exploration Consultant CSA Global completed a desktop review of Lithium-Caesium-Tantalum (LCT) pegmatite potential over Ardea’s tenements including a project ranking (ASX release 22 November 2022). The Perrinvale Project (Figure 5) ranked as the highest priority area for pegmatite-hosted LCT mineralisation. During FY23 lithium exploration has focused on testing LCT pegmatite targets at the Perrinvale project and also the Ghost Rocks project (Figure 5). The Perrinvale Project had no previous exploration for LCT pegmatites. During FY23 multiple mapping and sampling programs were completed with a total of 91 samples of extensive outcropping pegmatites taken, with some pegmatites extending >200m along strike, up to 20m thick and with variable mineralogy. Assay results were received from 82 samples from the LCT pegmatite rock chip sampling programs and await detailed interpretation. Further mapped pegmatites are still to be sampled, mostly in the northern and western part of the tenement. Sampling of the untested komatiite ultramafic at Perrinvale that extends for over 8km strike was also completed. Initial assay result interpretation showed an increase in MgO values across the unit heading east (possibly indicating the eastern contact is the base of flow). At the Ghost Rocks Project multiple field sampling and mapping programs were completed during FY23, with a total of 132 samples of extensive outcropping pegmatites taken, with some pegmatites >10m thick, up to 500m long and with variable mineral species. Initial assay results were received from 64 samples from the LCT pegmatite rock chip sampling and await detailed interpretation. To date assay results show the southern pegmatites as most prospective. Additional pegmatite swarms have recently been identified outside this prospective zone on the east side of the internal granite and await sampling. As for Perrinvale, detailed interpretation of the Ghost Rocks LCT potential will be completed once all assays are to hand. .

The Remuneration Report provides information about the remuneration of Ardea Resources Limited’s key management personnel (‘KMP’), being those executives with authority and responsibility for planning, directing, and controlling the activities of the Consolidated Entity, and its non-executive directors. The Remuneration Report has been prepared in accordance with the requirements of the Corporations Act 2001 and contains the following sections: Section 1 Remuneration at Ardea Resources Limited Section 2 Performance and Executive Remuneration Outcomes Section 3 Non-Executive Director Remuneration Section 4 Statutory Remuneration Disclosures This section of the Remuneration Report provides an overview of Ardea Resources Limited’s remuneration principles and the structure of remuneration for KMP. This section details the remuneration outcomes for Ardea Resources Limited’s KMP in the financial year.

Ardea Resources Limited & controlled entities Annual Report 2023 - page 36 Directors’ Report continued Section 1: Remuneration at Ardea Resources Limited The Board of Directors is responsible for approving the compensation arrangements for the Directors and KMP. The Board has formed the view that given the number of Directors on the Board, this function could be performed just as effectively with full Board participation. Accordingly, it was resolved that there would be no separate Board sub-committee for remuneration purposes and Remuneration Committee meetings would be made up of the full board. The Board regularly assesses the appropriateness of the nature and amount of emoluments of such officers on a periodic basis by reference to relevant employment market conditions, with the overall objective of ensuring maximum stakeholder benefit from the retention of a high-quality Board and executive team. Compensation levels are set to attract and retain appropriately qualified and experienced directors and executives. As and when required the Board has access to independent advice on the appropriateness of compensation packages given trends in comparative companies and the objectives of the compensation strategy. Non-executive director remuneration consists of fixed directors’ fees and an equity-based component (Committee fees are included in the base fee). KMP remuneration is structured to consist of fixed and variable remuneration. The KMP compensation structures explained below are designed to reward the achievement of strategic objectives, align performance with shareholder interests and create the broader outcome of creating value for shareholders. The compensation structures take into account: (i) The relevant person’s duties and responsibilities; and (ii) Ensure that total remuneration is competitive by market standards. KMP remuneration and incentive policies and practices are performance-based and aligned to the Consolidated Entity’s vision, values and overall business objectives. They are designed to motivate KMP to pursue the Consolidated Entity’s long-term growth and success. Compensation packages include a mix of fixed and variable compensation and short and long-term performance-based incentives. In addition to salaries, the Consolidated Entity may also provide non-cash benefits to its directors and key management personnel and contributes to post-employment superannuation plans on their behalf. Fixed remuneration Total Fixed Remuneration (‘TFR’) consists of base compensation (which is calculated on a total cost basis and includes any fringe benefits tax charges related to employee benefits), as well as leave entitlements and employer contributions to superannuation funds. Compensation levels are reviewed at least annually by the Board through a process that considers individual, segment, and overall performance of the Consolidated Entity. An external consultant had been engaged during the financial year to review the compensation level of the Non-Executive Director, Executive Director, Managing Director and CEO, and the CFO. The 2023 Remuneration Review was independently conducted by specialist consultant, The Reward Practice (TRP).TRP is a remuneration consulting practice based in Western Australia, specialising in board, executive and employee reward and recognition programs. The 2023 Remuneration Review noted that the total fixed remuneration and equity grant are within the average range of comparator companies. Ardea Resources Limited & controlled entities Annual Report 2023 - page 37 Directors’ Report continued Performance-linked remuneration Ardea Resources Limited’s approach to remuneration is to ensure that remuneration received by KMP is closely linked to the Consolidated Entity’s performance and the returns generated for shareholders. Performance-linked compensation, as outlined in the Consolidated Entity’s Employee Securities Inventive Plan (ESIP), includes long- term incentives, and is designed to incentivise and reward employees for meeting or exceeding Company-wide and individual objectives. The long-term incentive (’LTI’) is provided as performance rights over ordinary shares of the Company and cash bonuses. The LTI plans provide for the Board to be able to exercise discretion on the award of performance rights. Within the established remuneration framework, each employee is assigned a level that reflects the seniority and responsibility associated with their role. This level determines an employee’s participation in the LTI, and therefore, the proportion of their total remuneration which is linked to performance. Senior executives of the Company have a higher proportion of their total potential remuneration ‘at risk’. The Board considers that the performance-linked compensation structure outlined in the ESIP will generate the desired outcome in respect of attracting and retaining high-calibre employees and aligning employee performance with shareholder interests. Refer to Section 2 of this Remuneration Report for an analysis of the Consolidated Entity’s performance in the financial year ended 30 June 2023 and link to overall remuneration. Short Term Incentive The STI will be considered in future years to link employee remuneration to key business outcomes which drive value creation in the short to medium term. It is proposed that each year, all employees have individual key performance indicators (‘KPI’s’) agreed with their manager. The Board approves the individual KPI’s for the MD/CEO based on the recommendation of the RC. The MD/CEO approves the individual KPI’s for the KMP with endorsement from the RC. The individual performance objectives are designed to focus employees on goals and objectives specific to their roles and typically include financial performance compared to budgeted amounts as well as non-financial metrics which vary with position and responsibility and include measures such as completion of specific tasks and projects as well as health, safety and environment outcomes and staff development. Long Term Incentive The LTI has been adopted to align employees’ interests directly with shareholders by linking employee remuneration to the Company’s share price performance over the medium to longer term. The LTI comprises grants of performance rights to all employees, and cash bonuses to certain senior executives, pursuant to the Company’s ESIP Rules which were approved by shareholders at the 2017 and updated at the 2020 and 2022 AGM. The ESIP provides for certain key executives and employees to receive, for no consideration, performance rights. The performance rights convert to shares of the Company at specified exercise prices as determined by the Board. The grant of performance rights is intended to align the interests of senior executives and employees with other owners of the Company over the medium to longer term and to increase those senior executives’ and employees’ proportion of ‘at risk’ remuneration. The ability to exercise the performance rights is conditional upon each key executive’s ongoing employment by the Company and other applicable vesting hurdles determined by the Board from time to time. Ardea Resources Limited & controlled entities Annual Report 2023 - page 38 Directors’ Report continued Section 2: Performance and Executive Remuneration Outcomes During the financial year ended 30 June 2023 the Consolidated Entity made good progress towards achieving its strategic objectives, resulting in the Company’s Share price reaching the required performance right vesting conditions. STI Performance and Outcomes During the financial year, there were nil STI issued (2022: nil). LTI Performance and Outcomes During the financial year a portion of granted Performance Rights vested on 30 November 2022 due to the completion of the performance periods. Those tranches of Performance Rights met the performance hurdles and have been converted to shares. Performance Criteria for Performance Rights The performance criteria for the tranches of new performance rights granted to KMP during the financial year are detailed below.

Ardea Resources Limited & controlled entities Annual Report 2023 - page 48 Directors’ Report continued ASX CHAPTER 5 COMPLIANCE AND PFS CAUTIONARY STATEMENT The Company has concluded that it has a reasonable basis for providing the forward-looking statements and forecast financial information included in this announcement. The detailed reasons for that conclusion are outlined throughout this announcement and all material assumptions, including the JORC modifying factors, upon which the forecast financial information is based are disclosed in this announcement. This announcement has been prepared in accordance with the JORC Code (2012) and the ASX Listing Rules. The actual results could differ materially from a conclusion, forecast or projection in the forward-looking information. Certain material factors were applied in drawing a conclusion or making a forecast or projection as reflected in the forward-looking information. The KNP Goongarrie Hub Project is at the PFS phase and although reasonable care has been taken to make sure that the facts are accurate and/or that the opinions expressed are fair and reasonable, no reliance can be placed for any purpose whatsoever on the information contained in this document or on its completeness. Actual results and developments of projects and the scandium market development may differ materially from those expressed or implied by these forward- looking statements depending on a variety of factors. A key conclusion of the PFS, which are based on forward looking statements, is that the Goongarrie Hub is considered to have positive economic potential. The Mineral Resource used for the PFS was classified under JORC Code (2012) Guidelines and announced by the Company on 30 June 2023. The cut-off grades adapted for the PFS and reported in Table 2 are the basis of the production target assumed for the PFS. The Company believes it has a reasonable basis to expect to be able to fund and further develop the KNP Goongarrie Hub. However, there is no certainty that the Company can raise funding when required.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The principal accounting policies adopted in preparing the financial report of the Company, Ardea Resources Limited and its controlled entities (“Ardea” or “Consolidated Entity”), are stated to assist in a general understanding of the financial report. These policies have been consistently applied as presented, unless otherwise indicated. Ardea Resources Limited is a Company limited by shares incorporated and domiciled in Australia whose shares are publicly traded on the official list of the Australian Securities Exchange. The financial statements are presented in Australian dollars which is the Consolidated Entity’s functional currency. (a) Basis of Preparation This general purpose financial report has been prepared in accordance with Australian Accounting Standards (including Australian Interpretations) adopted by the Australian Accounting Standards Board and the Corporations Act 2001. Ardea Resources Limited is a for-profit entity for the purpose of preparing the financial statements. The financial report has been prepared on the basis of historical costs and does not take into account changing money values or, except where stated, current valuations of non-current assets. The financial report was authorised for issue by the Directors. (b) Use of Estimates and Judgements The preparation of financial statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and reported amounts of assets and liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised and in any future periods affected. The only significant estimate in the financial report is the R&D incentive rebate accrued which is based on management’s estimate of the eligible expenditure incurred in the year. (c) Basis of Consolidation Controlled Entities The consolidated financial statements comprise the financial statements of Ardea Resources Limited and its subsidiaries as at 30 June 2023. The financial statements of the subsidiaries are prepared for the same reporting period as the parent company, using consistent accounting policies. In preparing the consolidated financial statements, all intercompany balances and transactions, income and expenses and profit and losses resulting from intra-group transactions have been eliminated in full. The subsidiaries are fully consolidated from the date on which control is transferred to the consolidated entity and ceases to be consolidated from the date on which control is transferred out of the consolidated entity. The acquisition of the subsidiaries have been accounted for using the purchase method of accounting. The purchase method of accounting involves allocating the cost of the business combination to the fair value of the assets acquired and the liabilities and contingent liabilities assumed at the date of acquisition. Accordingly, the consolidated financial statements include the results of the subsidiaries for the period from their acquisition. (d) Income Tax The income tax expense or revenue for the period is the tax payable on the current period’s taxable income based on the income tax rate adjusted by changes in deferred tax assets and liabilities attributable to temporary differences between the tax bases of assets and liabilities and their carrying amounts in the financial statements, and to unused tax losses. Deferred tax assets and liabilities are recognised for temporary differences at the tax rates expected to apply when the assets are recovered or liabilities are settled, based on those tax rates which are enacted. The relevant tax rates are applied to the cumulative amounts of deductible and taxable temporary differences to measure the deferred tax asset or liability. An exception is made for certain temporary differences arising from the initial recognition of an asset or a liability. No deferred asset or liability is recognised in relation to those temporary differences if they arose in a transaction, other than a business combination, that at the time of the transaction did not affect either accounting profit or taxable profit or loss. Ardea Resources Limited & controlled entities Annual Report 2023 - page 55 Notes to the Financial Statements continued Deferred tax assets are recognised for deductible temporary differences and unused tax losses only if it is probable that future taxable amounts will be available to utilise those temporary differences and losses. Current and future tax balances attributable to amounts recognised directly in equity are also recognised directly in equity. (e) Revenue Recognition Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Consolidated Entity and the revenue can be reliably measured. The following specific recognition criteria must also be met before revenue is recognised: Interest income Interest revenue is recognised on a time proportionate basis that takes into account the effective yield on the financial asset. (f) Cash and Cash Equivalents Cash and short-term deposits in the balance sheet comprise cash at bank and in hand and short term deposits with an original maturity of three months or less. For the purposes of the Consolidated Statement of Cash Flows, cash and cash equivalents consist of cash and cash equivalents as defined above, which are readily convertible to cash on hand and which are used in the cash management function on a day-to-day basis. (g) Employee Entitlements Liabilities for wages and salaries, annual leave and other current employee entitlements expected to be settled within 12 months of the reporting date are recognised in other payables in respect of employees’ services up to the reporting date and are measured at the amounts expected to be paid when the liabilities are settled. Liabilities for non-accumulating sick leave are recognised when the leave is taken and measured at the rates paid or payable. Other long-term employee benefits The Consolidated Entity’s net obligation in respect of long-term employee benefits is the amount of future benefit that employees have earned in return for their service in the current and prior periods plus on-costs; that benefit is discounted to determine its present value. The discount rate is the yield at the reporting date on AA credit-rated (Corporate bond rate) bonds that have maturity dates approximating the terms of the consolidated entity’s obligations. Contributions to employee superannuation plans are charged as an expense as the contributions are paid or become payable. (h) Property, Plant and equipment Each class of property, plant and equipment is carried at cost or fair value less, where applicable, any accumulated depreciation and impairment losses. Property, plant and equipment and Motor Vehicles Property, Plant and equipment, and Motor Vehicles are stated at cost less accumulated depreciation and any impairment in value. The carrying values of property, plant and equipment and Motor Vehicles are reviewed for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. For an asset that does not generate largely independent cash flows, the recoverable amount is determined for the cash-generating unit to which the asset belongs. If any such indication exists where the carrying values exceed the estimated recoverable amount, the assets or cash generating units are written down to their recoverable amount. Depreciation Depreciable non-current assets are depreciated over their expected economic life using either the straight line or the diminishing value method. Profits and losses on disposal of non-current assets are taken into account in determining the operating loss for the year. The depreciation rate used for each class of assets is as follows: Plant & equipment and Motor Vehicles 20 - 33% (i) Goods and Services Tax (GST) Revenues, expenses and assets are recognised net of the amount of goods and services tax (“GST”), except where the amount of GST incurred is not recoverable from the Australian Taxation Office (“ATO”). In these circumstances the GST is recognised as part of the cost of acquisition of the asset or as part of an item of the expense. Receivables and payables are stated with the amount of GST included. GST incurred is claimed from the ATO when a valid tax invoice is provided. The net amount of GST recoverable from, or payable to, the ATO is included as a current asset or liability in the balance sheet. Cash flows are included in the statement of cash flows on a gross basis. The GST components of cash flows arising from investing and financing activities which are recoverable from, or payable to, the ATO are classified as operating cash flows. Ardea Resources Limited & controlled entities Annual Report 2023 - page 56 Notes to the Financial Statements continued (j) Payables These amounts represent liabilities for goods and services provided to the Consolidated Entity prior to the end of the financial period and which are unpaid. The amounts are unsecured and are usually paid within 30 days of recognition. (k) Contributed Equity Issued capital is recognised as the fair value of the consideration received by the Company. Any transaction costs arising on the issue of ordinary shares are recognised directly in equity as a reduction of the share proceeds received. (l) Exploration and Evaluation Expenditure Mineral exploration and evaluation expenditure incurred is accumulated in respect of each identifiable area of interest and is subject to impairment testing. These costs are carried forward only if they relate to an area of interest for which rights of tenure are current and in respect of which: (cid:183) (cid:183) such costs are expected to be recouped through the successful development and exploitation of the area of interest, or alternatively by its sale; or exploration and/or evaluation activities in the area have not reached a stage which permits a reasonable assessment of the existence or otherwise of economically recoverable reserves and active or significant operations in, or in relation to, the area of interest are continuing. In the event that an area of interest is abandoned or if the Directors consider the expenditure to be of reduced value, accumulated costs carried forward are written off in the year in which that assessment is made. A regular review is undertaken of each area of interest to determine the appropriateness of continuing to carry forward costs in relation to that area of interest. Where a mineral resource has been identified and where it is expected that future expenditures will be recovered by future exploitation or sale, the impairment of the exploration and evaluation is written back and transferred to development costs. Once production commences, the accumulated costs for the relevant area of interest are amortised over the life of the area according to the rate of depletion of the economically recoverable reserves. Costs of site restoration and rehabilitation are recognised when the Consolidated Entity has a present obligation, the future sacrifice of economic benefits is probable and the amount of the provision can be reliably estimated. The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the reporting date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows. Exploration and evaluation assets are assessed for impairment if: (i) (ii) sufficient data exists to determine technical feasibility and commercial viability, and facts and circumstances suggest that the carrying amount exceeds the recoverable amount. For the purpose of impairment testing, exploration and evaluation assets are allocated to cash- generating units to which the exploration activity relates. The cash generating unit shall not be larger than the area of interest. Once the technical feasibility and commercial viability of the extraction of mineral resources in an area of interest are demonstrable, exploration and evaluation assets attributable to that area of interest are first tested for impairment and then re-classified from intangible assets to mining property and development assets within property, plant and equipment. (m) Earnings per Share Basic earnings per share (“EPS”) are calculated based upon the net loss divided by the weighted average number of shares. Diluted EPS are calculated as the net loss divided by the weighted average number of shares and dilutive potential shares. (n) Financial risk management The Board of Directors has overall responsibility for the establishment and oversight of the risk management framework, to identify and analyse the risks faced by the Consolidated Entity. These risks include credit risk, liquidity risk and market risk from the use of financial instruments. The Consolidated Entity has only limited use of financial instruments through its cash holdings being invested in short term interest bearing securities. The primary goal of this strategy is to maximise returns while minimising risk through the use of accredited Banks with a minimum credit rating of A1 from Standard & Poors. The Consolidated Entity has no debt, and working capital is maintained at its highest level possible and regularly reviewed by the full board. Ardea Resources Limited & controlled entities Annual Report 2023 - page 57 Notes to the Financial Statements continued (o) Leases The Group as lessee At inception of a contract, the Group assesses if the contract contains a lease or is a lease. If there is a lease present, a right-of-use asset and a corresponding lease liability are recognised by the Group where the Group is a lessee. However, all contracts that are classified as short-term leases (i.e. a lease with a remaining lease term of 12 months or less) and leases of low-value assets are recognised as an operating expenses on a straight-line basis over the term of the lease. Initially the lease liability is measured at the present value of the lease payments still to be paid at the commencement date. The lease payments are discounted at the interest rate implicit in the lease. If this rate cannot be readily determined, the Group uses the incremental borrowing rate. All lease payments are included in the measurement of the lease liability. The right-of-use assets comprise the initial measurement of the corresponding lease liability, any lease payments made at or before the commencement date and any initial direct costs. The subsequent measurement of the right-of-use assets is at cost less accumulated depreciation and impairment losses. Right-of-use assets are depreciated over the lease term or useful life of the underlying asset, whichever is the shortest. (p) Share-based payment transactions The Company provides benefits to employees (including Directors and consultants) of the Consolidated Entity in the form of share-based payment transactions, whereby employees render services in exchange for shares or rights over shares (“Equity–settled transactions”). There is currently a plan in place to provide these benefits being an Employee Share Option Plan (“ESOP”) which provides benefits to Directors, consultants and senior executives. The cost of these equity-settled transactions is measured by reference to fair value at the date at which they are granted. The fair value is determined by an external valuer using either the Black - Scholes or Binomial model. In valuing equity-settled transactions, no account is taken of any performance conditions, other than conditions linked to the price of the shares of Ardea Resources Limited (“market conditions”). The cost of equity settled securities is recognised, together with a corresponding increase in equity, over the period in which the performance conditions are fulfilled, ending on the date on which the relevant employees become fully entitled to the award (“vesting date”). Where the Consolidated Entity acquires some form of interest in an exploration tenement or an exploration area of interest and the consideration comprises share-based payment transactions, the fair value of the equity instruments granted is measured at grant date. The cost of equity securities is recognised within capitalised mineral exploration and evaluation expenditure, together with a corresponding increase in equity. (q) Financial instruments Recognition, initial measurement and derecognition Financial assets and financial liabilities are recognised when the Company becomes a party to the contractual provisions of the financial instrument, and are measured initially at fair value adjusted by transactions costs, except for those carried at fair value through profit or loss, which are measured initially at fair value. Subsequent measurement of financial assets and financial liabilities are described below. Financial assets are derecognised when the contractual rights to the cash flows from the financial asset expire, or when the financial asset and all substantial risks and rewards are transferred. A financial liability is derecognised when it is extinguished, discharged, cancelled or expires. Classification and subsequent measurement of financial assets Financial assets at fair value through profit and loss are limited to holdings of listed securities and are valued based on the quoted share price at the relevant reporting date with the associated changes in fair value through profit and loss. Other financial assets are measured at amortised cost. Classification and measurement of financial liabilities Financial liabilities are initially measured at fair value, and, where applicable, adjusted for transaction costs unless the Company designated a financial liability at fair value through profit or loss. All interest-related charges and, if applicable, changes in an instrument’s fair value that are reported in profit or loss are included within finance costs or finance income. (r) New accounting standards and interpretations AASB 2020-1: Amendments to Australian Accounting Standards – Classification of Liabilities as Current or Non-current The amendment amends AASB 101 to clarify whether a liability should be presented as current or non-current. Ardea Resources Limited & controlled entities Annual Report 2023 - page 58 Notes to the Financial Statements continued The Group plans on adopting the amendment for the reporting period ending 30 June 2024 along with the adoption of AASB 2022-6. The amendment is not expected to have a material impact on the financial statements once adopted. AASB 2022-6: Amendments to Australian Accounting Standards – Non-current Liabilities with Covenants AASB 2022-6 amends AASB 101 to improve the information an entity provides in its financial statements about liabilities arising from loan arrangements for which the entity’s right to defer settlement of those liabilities for at least 12 months after the reporting period is subject to the entity complying with conditions specified in the loan arrangement. It also amends an example in Practice Statement 2 regarding assessing whether information about covenants is material for disclosure. The Group plans on adopting the amendment for the reporting period ending 30 June 2024. The amendment is not expected to have a material impact on the financial statements once adopted. AASB 2021-2: Amendments to Australian Accounting Standards – Disclosure of Accounting Policies and Definition of Accounting Estimates The amendment amends AASB 7, AASB 101, AASB 108, AASB 134 and AASB Practice Statement 2. These amendments arise from the issuance by the IASB of the following International Financial Reporting Standards: Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2) and Definition of Accounting Estimates (Amendments to IAS 8). The Group plans on adopting the amendment for the reporting period ending 30 June 2024. The impact of the initial application is not yet known. AASB 2021-5: Amendments to Australian Accounting Standards – Deferred Tax related to Assets and Liabilities arising from a Single Transaction The amendment amends the initial recognition exemption in AASB 112: Income Taxes such that it is not applicable to leases and decommissioning obligations – transactions for which companies recognise both an asset and liability and that give rise to equal taxable and deductible temporary differences. The Group plans on adopting the amendment for the reporting period ending 30 June 2024. The impact of the initial application is not yet known. AASB 2021-7b & c: Amendments to Australian Accounting Standards – Effective Date of Amendments to AASB 10 and AASB 128 and Editorial Corrections AASB 2021-7b makes various editorial corrections to AASB 17 Insurance Contracts which applies to annual reporting periods beginning on or after 1 January 2023, with earlier application permitted. AASB 2021-7c defers the mandatory effective date (application date) of amendments to AASB 10 and AASB 128 that were originally made in AASB 2014-10: Amendments to Australian Accounting Standards – Sale or Contribution of Assets between an Investor and its Associate or Joint Venture so that the amendments are required to be applied for annual reporting periods beginning on or after 1 January 2025 instead of 1 January 2018. The Group plans on adopting the amendments for the reporting periods ending 30 June 2024 and 30 June 2026. The impact of initial application is not yet known. AASB 2022-7: Editorial Corrections to Australian Accounting Standards and Repeal of Superseded and Redundant Standards AASB 2022-7 makes editorial corrections to the following standards: AASB 7, AASB 116, AASB 124, AASB 128, AASB 134 and AASB as well as to AASB Practice Statement 2. It also formally repeals superseded and redundant Australian Account Standards as set out in Schedules 1 and 2 to the Standard. The Group plans on adopting the amendments for the reporting period ending 30 June 2024. The amendment is not expected to have a material impact on the financial statements once adopted. 2.

(e) Terms and Conditions of Contributed Equity Ordinary Shares The Company is a public Company limited by shares. The Company was incorporated in Perth, Western Australia. The Company’s shares are limited whereby the liability of its members is limited to the amount (if any) unpaid on the shares respectively held by them. Ordinary shares have the right to receive dividends as declared and, in the event of the winding up of the Company, to participate in the proceeds from the sale of all surplus assets in proportion to the number of shares held. Ordinary shares which have no par value, entitle their holder to one vote, either in person or by proxy, at a meeting of the Company. The Company’s objectives when managing capital are to safeguard their ability to continue as a going concern, so that they may continue to provide returns for shareholders and benefits for other stakeholders.

CONTRIBUTED EQUITY (Continued) (f) Capital Risk Management Due to the nature of the Consolidated Entity’s activities, being mineral development and exploration, the Consolidated Entity does not have ready access to credit facilities, with the primary source of funding being equity raisings. Therefore, the focus of the Consolidated Entity’s capital risk management is the current working capital position against the requirements to meet exploration programmes and corporate overheads. The Consolidated Entity’s strategy is to ensure appropriate liquidity is maintained to meet anticipated operating requirements, with a view to initiating appropriate capital raisings as required.

FINANCIAL INSTRUMENTS The Consolidated Entity’s activities expose it to a variety of financial risks and market risks. The Consolidated Entity’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimise potential adverse effects on the financial performance of the Consolidated Entity. (a) Interest Rate Risk The Consolidated Entity’s exposure to interest rate risk, which is the risk that a financial instrument’s value will fluctuate as a result of changes in market, interest rates and the effective weighted average interest rates on those financial assets, is not significant. Cash and cash equivalents are the only assets effected and the average interest rate received is 4.23% (2022: 0.24%). (b) Credit Risk The maximum exposure to credit risk, excluding the value of any collateral or other security, at balance date, is the carrying amount, net of any provisions for doubtful debts, as disclosed in the balance sheet and in the notes to the financial statements. The Consolidated Entity does not have any material credit risk exposure to any single debtor or group of debtors, under financial instruments entered into by it, and hence no credit loss allowance is required. (c) Commodity Price Risk and Liquidity Risk At the present state of the Consolidated Entity’s operations it has minimal commodity price risk and limited liquidity risk due to the level of payables and cash reserves held. The Consolidated Entity’s objective is to maintain a balance between continuity of exploration funding and flexibility through the use of available cash reserves. (d) Net Fair Values For assets and other liabilities, the net fair value approximates their carrying value. No financial assets and financial liabilities are readily traded on organised markets in standardised form. The Consolidated Entity has no financial assets where the carrying amount exceeds net fair values at balance date. The aggregate net fair values and carrying amounts of financial assets and financial liabilities are disclosed in the statement of financial position and in the notes to the financial statements. 22. EMPLOYEE ENTITLEMENTS AND SUPERANNUATION COMMITMENTS Employee Entitlements The aggregate employee entitlement liability is disclosed in Note 12. Superannuation Commitments The Consolidated Entity contributes to individual employee accumulation superannuation plans at the statutory rate of the employees’ wages and salaries, in accordance with statutory requirements, to provide benefits to employees on retirement, death or disability. Accordingly no actuarial assessments of the plans are required. 23. CONTINGENT LIABILITIES There were no material contingent liabilities not provided for in the financial statements of the Consolidated Entity as at 30 June 2023 other than: Native Title and Aboriginal Heritage Native title claims have been made with respect to areas which include tenements in which the Consolidated Entity has an interest. The Consolidated Entity is unable to determine the prospects for success or otherwise of the claims and, in any event, whether or not and to what extent the claims may significantly affect the Consolidated Entity or its projects. Agreement is being negotiated with various native title claimants in relation to Aboriginal Heritage issues regarding certain areas in which the Consolidated Entity has an interest.

EVENTS SUBSEQUENT TO BALANCE DATE There has not arisen since the end of the financial period any item, transaction or event of a material and unusual nature likely, in the opinion of the Directors of the Consolidated Entity to affect substantially the operations of the Consolidated Entity, the results of those operations or the state of affairs of the Consolidated Entity in subsequent financial years except for the following: On 30 August 2023 the company completed an equity raising to institutional and sophisticated investors with 22,767,143 new shares issued at 70 cents per share to raise $16,000,000 before costs. 25.

(ii) (b) there are reasonable grounds to believe that Ardea Resources Limited will be able to pay its debts as and when they become due and payable. The Directors have been given the declarations required by section 295A of the Corporations Act 2001 from the Managing Director and the Company Secretary for the year to 30 June 2023. This declaration is made in accordance with a resolution of the Directors. Signed at Perth this 27th day of September 2023. Mathew Longworth Chairman Ardea Resources Limited & controlled entities Annual Report 2023 - page 70 Independent Audit Report INDEPENDENT AUDITOR’S REPORT TO THE MEMBERS OF ARDEA RESOURCES LIMITED Report on the financial report Opinion We have audited the financial report of Ardea Resources Limited (“the Company”) and its controlled entities (“the Group”), which comprises the consolidated statement of financial position as at 30 June 2023 the consolidated statement of comprehensive income, the consolidated statement of changes in equity and the consolidated statement of cash flows for the year then ended, and notes to the financial statements, including a summary of significant accounting policies, and the directors’ declaration. In our opinion, the accompanying financial report of the Group is in accordance with the Corporations Act 2001, including: i) giving a true and fair view of the Group’s financial position as at 30 June 2023 and of its financial performance for the year then ended; and ii) complying with Australian Accounting Standards and the Corporations Regulations 2001. Basis for opinion We have conducted our audit in accordance with Australian Auditing Standards. Our responsibilities under those Standards are further described in the Auditor’s responsibilities for the audit of the financial report section of our report. We are independent of the Group in accordance with the auditor independence requirements of the Corporations Act 2001 and the ethical requirements of the Accounting Professional and Ethical Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) that are relevant to our audit of the financial report in Australia. We have also fulfilled our ethical requirements in accordance with the Code. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. Key Audit Matters Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial report of the current period. These matters were addressed in the context of our audit of the financial report as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. Ardea Resources Limited & controlled entities Annual Report 2023 - page 71 Independent Audit Report continued Key Audit Matter How our audit addressed the key audit matter Capitalised mineral exploration expenditure (refer note 10) Our audit procedures included: The Group operates as an exploration entity and its primary activity is the exploration for and evaluation of economically viable mineral deposits. All exploration and evaluation expenditure incurred has been capitalised and recognised as an asset in the Statement of Financial Position. The closing value of this asset is $35,426,032 as at 30 June 2023. The carrying value of capitalised mineral exploration assets is subjective and is based on the Group’s intention and ability, to continue to explore the asset. The carrying value may also be affected by the results of ongoing exploration activity indicating that the mineral reserves and resources may not be commercially viable for extraction. This creates a risk that the asset value included within the financial statements may not be recoverable. (cid:183) ensuring the Group’s continued right to explore for minerals in the relevant exploration areas including assessing documentation such as exploration and mining licences; (cid:183) enquiring of management and the directors as to the Group’s intentions and strategies for future exploration activity and reviewing budgets and cash flow forecasts; (cid:183) assessing the results of recent exploration activity to determine whether there are any indicators suggesting a potential impairment of the carrying value of the asset; (cid:183) assessing the Group’s ability to finance the planned exploration and evaluation activity; and (cid:183) assessing the adequacy of the disclosures made by the Group in the financial report. Research and Development Tax Incentive (refer notes 6 and 10) Our audit procedures included: Management and their advisors have applied in judgements, determining refund recognised for the 2023 year. assumptions the R&D Tax estimates Incentive and (cid:183) evaluating the assumptions, methodologies and conclusions used by the Group in preparing the R&D Tax Incentive estimate; and (cid:183) assessing the adequacy of the disclosures made by the Group in the financial report. Deferred Taxation (refer note 5) The Company relies on the use of an expert to prepare the taxation disclosures which are included in the financial statements. In accordance with Australian Auditing Standards, we relied on the work of management's expert with respect to the assumptions used in the calculation of deferred taxes. Our audit procedures included: (cid:183) examining the qualifications, objectivity and experience of management's expert; (cid:183) evaluating the assumptions, methodologies and conclusions used by the Group in preparing their estimate of deferred taxes; and (cid:183) assessing the adequacy of the disclosures made by the Group in the financial report. Ardea Resources Limited & controlled entities Annual Report 2023 - page 72 Independent Audit Report continued Equity and Capital Structure Refer note 13 During the year, the Company issued ordinary shares on the conversion of performance rights as well as various performance rights of which some have been exercised. Our audit procedures included an examination of the issue of ordinary shares during the year as disclosed in note 13. We also assessed whether share-based payments should have been recognised in relation to performance rights. Furthermore, we reconciled the third-party share registry to information announced to the public. Other information The directors are responsible for the other information. The other information comprises the information in the Group’s annual report for the period ended 30 June 2023, but does not include the financial report and the auditor’s report thereon. Our opinion on the financial report does not cover the other information and accordingly we do not express any form of assurance conclusion thereon. In connection with our audit of the financial report, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial report or our knowledge obtained in the audit or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard. Directors’ responsibilities for the financial report The directors of the Company are responsible for the preparation of the financial report that gives a true and fair view in accordance with the Australian Accounting Standards and the Corporations Act 2001 and for such internal control as the directors determine is necessary to enable the preparation of the financial report that gives a true and fair view and is free from material misstatement, whether due to fraud or error. In preparing the financial report, the directors are responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so. Auditor’s responsibilities for the audit of the financial report Our objectives are to obtain reasonable assurance about whether the financial report as a whole is free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Australian Auditing Standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the financial report. As part of an audit in accordance with the Australian Auditing Standards, we exercise professional judgement and maintain professional scepticism throughout the audit. We also: (cid:183) Identify and assess risks of material misstatement of the financial report, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient Ardea Resources Limited & controlled entities Annual Report 2023 - page 73 Independent Audit Report continued and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. (cid:183) Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s internal control. (cid:183) Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the directors. (cid:183) Conclude on the appropriateness of the directors’ use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the financial report or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Group to cease to continue as a going concern. (cid:183) Evaluate the overall presentation, structure and content of the financial report, including the disclosures, and whether the financial report represents the underlying transactions and events in a manner that achieves fair presentation. (cid:183) Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the financial report. We are responsible for the direction, supervision and performance of the Group audit. We remain solely responsible for our audit opinion. We communicate with the directors regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit. We also provide the directors with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, actions taken to eliminate threats or safeguards applied. From the matters communicated with the directors, we determine those matters that were of most significant in the audit of the financial report of the current period and are therefore key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh public interest benefits of such communication. Report on the remuneration report Opinion We have audited the remuneration report included on pages 36 to 47 of the directors’ report for the year ended 30 June 2023. In our opinion, the remuneration report of Ardea Resources Limited, for the year ended 30 June 2023, complies with section 300A of the Corporations Act 2001. Ardea Resources Limited & controlled entities Annual Report 2023 - page 74 Independent Audit Report continued Responsibilities The directors of the Company are responsible for the preparation and presentation of the remuneration report in accordance with section 300A of the Corporations Act 2001.

Ardea Resources Limited & controlled entities Annual Report 2023 - page 81 Glossary ASIC ASIC means Australian Securities and Investments Commission ASX means ASX Limited (ABN 98 008 624 691) or the Australian Securities Exchange, as appropriate Australian Registry means Security Transfer Registrars Pty Ltd of 770 Canning Highway, Applecross WA Ardea or ARL or Company means Ardea Resources Limited (ABN: 30 614 289 342) ARL : ASX is the Ardea code on ASX AL means Atmospheric Leach (being a hydrometallurgical process done at atmospheric pressure, in contrast to high pressure leach HPAL) Au means Gold Anomaly means a value higher or lower than expected, which outlines a zone of potential exploration interest but not necessarily of commercial significance Austrade - Australian Trade and Investment Commission Co means Cobalt CMO means Australian Federal Government - Critical Minerals Office Critical Minerals means metals and non-metals that are considered vital for the economic well-being of the world's major and emerging economies, yet whose supply may be at risk due to geological scarcity, geopolitical issues, trade policy or other factors. The minerals ranked by Geoscience Australia: Rare-earth elements (REE), gallium (Ga), germanium (Ge), graphite, hafnium (Hf), helium (He), indium (In), tungsten (W), platinum-group elements (PGE) including platinum (Pt) and palladium (Pd), cobalt (Co), niobium (Nb), magnesium (Mg), antimony (Sb), beryllium (Be), bismuth (Bi), lithium (Li), rhenium (Re), vanadium (V),tantalum (Ta), titanium (Ti), chromium (Cr), scandium (Sc), zirconium (Zr) and manganese (Mn). Cu means Copper DFAT means Australian Federal Government - Department of Foreign Affairs and Trade DHEM means downhole electromagnetics DWER means WA Department of Water and Environmental Regulation EFA means Export Finance Australia EM means electromagnetics EV means Electric Vehicle ESG means Environmental Social and Governance principles Feasibility study means a study with three progressively more detailed stages: Scoping Study means a first pass estimate of engineering requirements and costs of a mining operation, processing plant and plant infrastructure. Included in the cost estimates will be infrastructure, tailings disposal, power supply, and owner's costs. The plant design may change as a result of test work analysis, optimisation studies and engineering improvements performed during execution of the follow-up Pre-feasibility Study. Operating and capital cost estimates are to an order of magnitude accuracy of ± 30%. Pre-feasibility Study (PFS) means an engineering and cost study of a mining operation, processing plant and plant infrastructure. Included in the cost estimates will be infrastructure, tailings disposal, power supply, and owner's costs. The plant design may change as a result of test work analysis, optimisation studies and engineering improvements performed during execution of the Pre-feasibility Study. Operating and capital cost estimates are to an accuracy of ± 25%. Definitive Feasibility Study (DFS) means a feasibility study undertaken to a high degree of accuracy which may be used as a basis for raising finance for the construction of a project. Typically operating and capital cost estimates are to an accuracy of +/- 15-20%. A DFS is the standard of report required by primary debt funders to demonstrate the technical and commercial viability of a project. FBICRC means Future Batteries Industry Co-operative Research Centre of which Ardea is a member Goethite means the dominant nickel cobalt ore type at Goongarrie, which is free dig and has a low energy requirement for comminution along with low acid consumption during processing. GWL means groundwater extraction licences HPAL means High-Pressure Acid Leach Ardea Resources Limited & controlled entities Annual Report 2023 - page 82 Glossary continued KNP means Kalgoorlie Nickel Project, a nickel cobalt laterite project located through an arc 30 to 150km north-north west to east of Kalgoorlie. It is comprised of the: Goongarrie Hub – Goongarrie South, Goongarrie Hill, Highway, Ghost Rocks, Big Four, Scotia, Black Range and Siberia deposits Kalpini Hub – Kalpini and Bulong deposits Yerilla Hub – Jump Up Dam, Boyce Creek, Aubils and Lake Rebecca deposits LIB means Lithium Ion Battery LCA means Life Cycle Assessment m means metre and km means kilometres Mt means Million tonnes Mineralisation means in economic geology, the introduction of valuable elements into a rock body Mineralised Neutraliser means a specific plant feed unique to the Goongarrie Hub for which the fine component is AL feed and coarse component is a neutraliser MHP means Mixed Hydroxide Precipitate MPFA means Australian Federal Government - Major Projects Facilitation Agency MPS means Major Project Status - KNP was award MPS in March 2022 by the Prime Minister of Australia MSP means Mixed Sulphide Precipitate Ni means Nickel Nickel Laterite means Nickel occurring as an oxidised hydrated iron oxide, ferruginous clay, smectite clay, chlorite and serpentine assemblage overlying weathered ultramafic rock Nickel Sulphide means nickel occurring in an un-oxidised sulphide assemblage associated with fresh ultramafic rock NCM means Nickel-Cobalt-Manganese OEM mean Original Equipment Manufacturers OECD means Organisation for Economic Cooperation and Development PCAM Precursor Cathode-active Material PGE means Platinum Group Metals - Ruthenium (Ru), Rhodium (Rh), Palladium (Pd), Osmium (Os), Iridium (Ir), and Platinum (Pt) PLS means Pregnant Liquor Solution Project means a grouping of prospects within a specific geographic location, often with a common geological setting Prospect means a target upon which exploration programs are planned or have commenced R&D means Research and Development RC means Reverse Circulation drilling method employing a rotating or hammering action on a drill bit which returns a sample to the surface inside the rod string by compressed air. Sample quality is very good, particularly if the drill hole is dry. REE means Rare Earth Elements, notably Neodymium (Nd), Praseodymium (Pr) and Cerium (Ce). Reserves or Ore Reserves or Mineral Reserves as defined by JORC Code. Proven or Proved Ore Reserve means the economically mineable part of a Measured Mineral Resource. It includes diluting materials and allowances for losses which may occur when the material is mined. Appropriate assessments, which may include Feasibility Studies, have been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified. The term "economic" implies that extraction of the Ore Reserve has been established or analytically demonstrated to be viable and justifiable under reasonable investment assumptions. Probable Ore Reserve is the economically mineable part of an Indicated Mineral Resource. Ardea Resources Limited & controlled entities Annual Report 2023 - page 83 Glossary continued Resource or Mineral Resource (MRE) means a Mineral Resource Estimate as defined by JORC Code and is a concentration or occurrence of material of intrinsic economic interest in or on the earth’s crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction. Mineral Resources are further sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories. Measured Resource means a ‘Measured Mineral Resource’ is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit. Geological evidence is derived from detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes, and is sufficient to confirm geological and grade (or quality) continuity between points of observation where data and samples are gathered. A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proved Ore Reserve or under certain circumstances to a Probable Ore Reserve. Indicated Resource means an ‘Indicated Mineral Resource’ is that part of a Mineral Resource for which quantity, grade (or quality), densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes, and is sufficient to assume geological and grade (or quality) continuity between points of observation where data and samples are gathered. An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Ore Reserve. Inferred Resource means an ‘Inferred Mineral Resource’ is that part of a Mineral Resource for which quantity and grade (or quality) are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade (or quality) continuity. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to an Ore Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continue exploration. JORC (2012 edition) means the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves and is a professional code of practice that sets minimum standards for Public Reporting of minerals Exploration Results, Mineral Resources and Ore Reserves. The JORC Code provides a mandatory system for the classification of minerals Exploration Results, Mineral Resources and Ore Reserves according to the levels of confidence in geological knowledge and technical and economic considerations in Public Reports. Sc means Scandium SSB means Static Storage Battery V means Vanadium WA means Western Australia WWF means Walter Williams Formation, the dominant host unit that has weathered to form the Goongarrie Hub nickel laterite deposits and potentially prospective for hosting magmatic nickel sulphide WU, CU, EU means ultramafic units Western Ultramafic, Central Ultramafic and Eastern Ultramafic at the Kalpini nickel sulphide project. The WU and CU units are the prime nickel sulphide targets.
