Basis of preparation [Abstract]
Basis of preparation	Section 1. Basis of preparation INTRODUCTION - What’s New in this Report 1.1. Reporting entity The financial report of ioneer Ltd for the year ended 30 June 2024 was authorised for issue in accordance with a resolution of the Directors on September 18, 2024. ioneer Ltd is a for profit company limited by shares and incorporated in Australia whose shares are publicly traded on the Australian Securities Exchange under the ticker code “INR” and on Nasdaq under ticker code “IONR”. The registered office of the Company is suite 16.01, 213 Miller Street, North Sydney, NSW 2060 Australia. The Company is principally engaged in the development of the Rhyolite Ridge lithium-boron deposit in the state of Nevada, United States of America. Further information about the nature of the Group’s operations and activities is provided in the directors’ report. Information on the group structure is set out in Section 8 of this report and information on other related party disclosures of the Group is provided in Section 9. 1.2. Basis of preparation • These financial statements comply with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board ('IASB'), including new or amended accounting standards effective for reporting periods beginning July 1 2022. • Unless otherwise stated, the accounting policies disclosed have been consistently applied. • The financial report has been prepared on a historical cost basis. • The financial statements have been presented in US dollars which is the Groups presentation currency. • The financial statements have been prepared on the going concern basis which assumes the company and consolidated entity will have sufficient cash to pay its debts as and when they become payable for a period of at least 12 months from the date the financial report was authorised for issue. 1.3. New and amended accounting standards and interpretations The Group has adopted all the new or amended Accounting Standards and Interpretations issued by the International Accounting Standards Board (“IASB”) that are mandatory for the current reporting period. Any new or amended Accounting Standards or Interpretations that are not yet mandatory have not been early adopted. The adoption of these Accounting Standards and Interpretations did not have any significant impact on the financial performance or position of the Group. The following standards and interpretations that have recently been issued but are not yet mandatory, have not been early adopted by the Group for the annual reporting period ended June 30, 2024. The Group’s assessment of the impact of these new or amended Accounting Standards and Interpretations, which are most relevant to the Group are set out below: Classification of Liabilities as Current or Non-current (IAS 1) A liability is classified as current if the entity has no right at the end of the reporting period to defer settlement for at least 12 months after the reporting period. The IASB issued amendments to IAS 1 Presentation of Financial Statements to clarify the requirements for classifying liabilities as current or non-current. Specifically: • The amendments specify that the conditions which exist at the end of the reporting period are those which will be used to determine if a right to defer settlement of a liability exists. • Management intention or expectation does not affect classification of liabilities. • In cases where an instrument with a conversion option is classified as a liability, the transfer of equity instruments would constitute settlement of the liability for the purpose of classifying it as current or non-current. These amendments had no material impact on the financial statements. Amendments to IAS 8 – Disclosure of Accounting Estimates The definition of a change in accounting estimates is replaced with a definition of accounting estimates. Under the new definition, accounting estimates are “monetary amounts in financial statements that are subject to measurement uncertainty”. Entities develop accounting estimates if accounting policies require items in financial statements to be measured in a way that involves measurement uncertainty. These amendments had no material impact on the financial statements. Amendments to IAS 12 - Deferred Tax related to Assets and Liabilities arising from a Single Transaction The initial recognition exemption has been narrowed such that it no longer applies to transactions that, on initial recognition, give rise to equal amounts of taxable and deductible temporary differences. These amendments had no material impact on the financial statements. 1.4. Basis of consolidation Controlled entities Controlled entities are entities controlled by the Company. Control exists when the Company has the power, directly or indirectly to govern the financial and operating policies of an entity so as to obtain benefits from its operations. The financial statements of controlled entities are included in the consolidated financial statements from the date control commences until the date that control ceases. With the exception of the wind up of three Canadian entities during the financial year there has been no change in the control of any subsidiaries during the financial period. All subsidiaries are 100% owned by the Company (2023: 100%). Transactions eliminated on consolidation All inter-company balances and transactions, including unrealized profits arising from intra-group transactions, have been eliminated in full. Accounting policies The financial statements of subsidiaries are prepared for the same reporting period as the parent company, using consistent accounting policies. 1.5 Current versus non-current classification The Group presents assets and liabilities in the statement of financial position based on current/non-current classification. An asset is current when it is: - Expected to be realised or intended to be sold or consumed in the normal operating cycle - Held primarily for the purpose of trading - Expected to be realised within twelve months after the reporting period Or - Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period All other assets are classified as non-current. A liability is current when: - It is expected to be settled in the normal operating cycle - It is held primarily for the purpose of trading - It is due to be settled within twelve months after reporting period Or - There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period The terms of the liability that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification. The Group classifies all other liabilities as non-current. Deferred tax assets and liabilities are classified as non-current assets and liabilities. 1.6. Critical accounting estimates and judgements The preparation of these financial statements in conformity with International Financial Reporting Standards has required management to make judgements, estimates and assumptions which impact the application of policies and reported amounts of assets and liabilities, income and expenses. These estimates and associated assumptions are based on historical knowledge and various other factors that are believed to be reasonable in the circumstance. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed regularly and revisions to accounting estimates are reviewed in the period in which the estimate is revised. The most significant estimates and assumptions which have a significant risk of causing material adjustment to the carrying amounts of assets and liabilities within the next financial year relate to: Reserve estimates Reserves are estimates of the amount of product that can be economically and legally extracted, processed and sold from the Groups properties under current and foreseeable economic conditions. The group determines and reports reserves under the standards incorporated in the Australian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves, 2012 edition (the JORC code). The SEC generally requires disclosure of mining reserves in accordance with Regulation S-K, Subpart 1300. The determination of ore reserves includes estimates and assumptions about a range of geological, technical and economic factors including quantities, grades, production techniques, recovery rates, commodity prices and exchange rates. Change in ore reserve impact the assessment of recoverability of exploration and evaluation assets. Estimating the quantity and /or grade of reserves requires the size, shape and depth of ore to be determined by analyzing geological data. This process may require complex and difficult judgements to interpret the data. Exploration and evaluation assets The Group’s policy for exploration and evaluation expenditure is set out in note 4.6. The application of this policy requires certain judgements, estimates and assumptions as to the future events and circumstances, in particular the assessment of whether economic quantities of reserves will be found. Any such estimates and assumptions may change as new information becomes available. If, after capitalization of expenditure under the policy, it is concluded that the capitalized expenditure will not be recovered by future exploitation or sale, then the relevant amount will be written off in the statement of profit or loss. Changes in assumptions may result in a material adjustment to the carrying amount of exploration and evaluation assets. Share-based payment transactions The Group measures the cost of equity-settled transactions with employees by reference to the fair value of the equity investments at the date on which they are granted. Additional information is set out in note 7.3, Share-based payments. 1.7. Foreign Currency Transactions and Balances Functional and presentation currency The functional currency of each of the Group’s entities is measured using the currency of the primary economic environment in which that entity operates. The functional currency of the entities in the Group is predominantly US Dollars, with the exception of ioneer Limited, which has a functional currency of Australian Dollars. Transactions and balances Foreign currency transactions are translated at the foreign exchange rate at the date of the transaction. Monetary assets and liabilities denominated in a foreign currency at the end of the reporting period are translated at the year-end exchange rate. Exchange differences arising on the translation of monetary items are recognized in the statement of profit or loss. Non-monetary items measured at historical cost continue to be carried at the exchange rate at the date of the transaction. Exchange differences arising on the translation of non-monetary items are recognized directly in other comprehensive income to the extent that the underlying gain or loss is recognized in other comprehensive income; otherwise, the exchange difference is recognized in profit or loss. Presentation of foreign exchange gains and losses in the statement of profit or loss The Group presents its foreign exchange gains and losses within net financing income /expense in the statement of profit or loss.

Diluted EPS is calculated by dividing the profit attributable to ordinary equity holders of the parent by the weighted average number of ordinary shares outstanding during the year plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares. The effect of dilution from options and rights on issue in the financial year would be 36,820,966 (2023: 35,840,492 and 2022: 35,597,029). The impact the potential ordinary shares is treated as dilutive only when their conversion to ordinary shares would decrease EPS.

Ioneer Ltd is not part of an Australian tax-consolidated group. Current and deferred tax amounts (if any) are measured as a stand-alone taxpayer. There are no tax funding arrangements or tax sharing agreements in place. The group has additional tax value embedded in the Rhyolite Ridge exploration asset. Future deductibility is expected against anticipated assessable income from the Project once in production.

Impairment losses are recognized in the profit and loss. 4.3. Current assets - other 2024 2023 $’000 $’000 Current Prepayments 19 - Total current other assets 19 - 4.4.

Depreciation is calculated on a straight-line basis over the useful life of the asset being between 1-4 years. An item of plant and equipment is derecognized upon disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the item) is included in the statement of comprehensive income in the period the item is derecognized. At each reporting date, the Group assesses whether there is any indication that an asset may be impaired. Where an indicator of impairment exists, the Group makes a formal estimate of recoverable amount. Where the carrying amount of an asset exceeds its recoverable amount the asset is considered impaired and is written down to its recoverable amount. Recoverable amount is the greater of fair value less costs to sell and value in use. 4.5. Right of Use Asset 2024 2023 $’000 $’000 Premises - at cost 368 356 Less accumulated amortization (297 ) (154 ) Total Right of Use Asset 71 202 Reconciliation of the movement Opening balance 202 245 Additions 11 161 Disposals - - Amortization expense (142 ) (206 ) Foreign exchange translation difference - 2 Closing balance 71 202 The Group recognizes right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Unless the Group is reasonably certain to obtain ownership of the leased asset at the end of the lease term, the recognized right-of-use assets are depreciated on a straight-line basis over the shorter of its estimated useful life and the lease term. Right-of-use assets are subject to impairment. 4.6. Exploration and evaluation expenditure Exploration and evaluation expenditure incurred by or on behalf of the Group is accumulated separately for each area of interest. Such expenditure comprises net direct costs and an appropriate portion of related overhead expenditure but does not include general overheads or administrative expenditure not having a specific connection with a particular area of interest. Exploration and evaluation costs in relation to separate areas of interest for which rights of tenure are current are brought to account in the year in which they are incurred and carried forward provided that: • such costs are expected to be recouped through successful development and exploitation of the area, or alternatively through its sale; or • exploration and/or evaluation activities in the area have not yet reached a stage which permits a reasonable assessment of the existence or otherwise of economically recoverable reserves. The types of costs recognized as exploration and evaluation assets include costs to acquire the legal rights to explore in the specific area and costs incurred in respect of the search for mineral resources, determination of technical feasibility and the assessment of commercial viability of an identified resource, in accordance with IFRS 6. A Final Investment Decision (FID) to develop the Project is expected to be made after considering the following key factors: required permits are in place, engineering has reached construction ready status, adequate offtake agreements have been signed to underwrite any debt requirements, and the Project is funded through a mix of equity and debt. In order to attract funding, the Project will need to demonstrate technical feasibility and commercial viability. Once FID has been taken, all past and future exploration and evaluation assets in respect of the area of interest are tested for impairment and transferred to the cost of development. To date, no development decision has been made. The Directors assess at each reporting date whether there is an indication that an asset has been impaired and for exploration and evaluation costs carried forward whether the above carry forward criteria are met. No indicator of impairment has been identified as at June 30 2024. When the above criteria do not apply or when the Directors assess that the carrying value may exceed the recoverable amount the accumulated costs in respect of areas of interest are written off in the Statement of profit and loss and other comprehensive income. 2024 2023 $’000 $’000 Exploration and evaluation expenditure 187,664 152,226 Reconciliation of movement Opening balance 152,226 118,487 Additions - Rhyolite Ridge 35,398 33,579 Exploration expenditure - non core 71 205 Exploration expenditure - written off (31 ) (45 ) Carrying amount at the end of the financial year 187,664 152,226 The above amounts represent costs of areas of interest carried forward as an asset in accordance with the accounting policy described above. The ultimate recoupment of exploration and evaluation expenditure in respect of an area of interest carried forward is dependent upon the discovery of commercially viable reserves and the successful development and exploitation of the respective areas or alternatively sale of the underlying areas of interest for at least their carrying value. Amortization, in respect of the relevant area of interest, is not charged until a mining operation has commenced. All exploration and evaluation costs carried forward relate in large part to the Rhyolite Ridge Lithium–Boron Project in Nevada, USA. Exploration and evaluation expenditure on all other tenements owned by the Company has been fully impaired where applicable. 4.7. Payables 2024 2023 $’000 $’000 Current Trade creditors and other payables 4,056 6,805 Accrued expenses 487 1,535 Lease Liabilities 41 134 Total current payables 4,584 8,474 Non-current Lease Liabilities 42 78 Total non-current payables 42 78 Total current and non-current payables 4,626 8,552 All financial liabilities are recognized initially at fair value net of directly attributable transaction costs. After initial measurement, financial liabilities are subsequently measured at amortized cost. Current payables, other than lease liabilities, due to their short-term nature are measured at amortized cost and are not discounted. The current payables, other than lease liabilities, are unsecured and are non-interest bearing generally on 30-60 day terms. The carrying amounts approximate fair value. At the commencement date of the lease, the Group recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in - substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group and payments of penalties for terminating a lease, if the lease term reflects the Group exercising the option to terminate. The variable lease payments that do not depend on an index or a rate are recognized as expense in the period on which the event or condition that triggers the payment occurs. In calculating the present value of lease payments, the Group uses the incremental borrowing rate at the lease commencement date if the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the in-substance fixed lease payments or a change in the assessment to purchase the underlying asset. 4.8. Borrowings 2024 2023 $’000 $’000 Current Other current debt 1,200 - Total borrowings 1,200 - C urrent debt is comprised of an unsecured loan from Sibanye Stillwater Limited. The loan will mature and be repaid in full 30 days following the termination of the strategic partnership unit purchase agreement (an agreement with Sibanye Stillwater Limited to make an equity investment of $490 million for a 50% share of the Rhyolite Ridge Project as announced on 16 September 2021) by either party, or alternatively, will be deducted from the initial capital commitment ($490 million) under the unit purchase agreement at closing (that is when all conditions precedent to the agreement are met and a final investment decision taken with Sibanye-Stillwater to develop the Rhyolite Ridge Project) . The interest rate is 0% to maturity date. If unpaid by maturity date, then the interest will be accrued at the Secured Overnight Financing Rate (SOFR) plus 8% per annum. The SOFR is the cost of borrowing cash overnight collateralised by Treasury securities. 4.9. Provisions Employee entitlements 2024 2023 $’000 $’000 Current Provision for employee benefits 428 368 Total provisions 428 368 Provision is made for the Group’s liability for employee benefits arising from services rendered by employees to the end of the reporting period. Employee benefits that are expected to be settled within one year have been measured at the amounts expected to be paid when the liability is settled. Employee benefits payable later than one year have been measured at the present value of the estimated future cash outflows to be made for those benefits. In determining the liability, consideration is given to employee wage increases and the probability that the employee may satisfy vesting requirements. Those cash flows are discounted using market yields on high quality corporate bonds with terms to maturity that match the expected timing of cash flows.

There are no restrictions on voting rights. On a show of hands every member present or by proxy shall have one vote and upon a poll each share shall have one vote. Where a member holds shares, which are not fully paid, the number of votes to which that member is entitled on a poll in respect of those part paid shares shall be that fraction of one vote which the amount paid up bears to the total issued price thereof. They have the right to receive dividends as declared and, in the event of winding up the Company, to participate in the proceeds from the sale of all surplus assets in proportion to the number of and amounts paid up on shares held. Incremental costs directly attributable to the issue of new shares, options or rights are shown in equity as a deduction from the proceeds. Management controls the capital of the Group in order to maintain a sustainable debt to equity ratio, generate long-term shareholder value and ensure that the Group can fund its operations and continue as a going concern.

The fair value of such compensation is measured using generally accepted valuation methodologies for pricing financial instruments, and incorporates all factors and assumptions that knowledgeable, willing market participants would consider in setting the price. The fair value of instruments granted is recognized as an expense or capitalized if appropriate over the vesting period with a corresponding increase in equity. The foreign currency translation reserve comprises all foreign exchange differences arising from the following: • The translation of the financial statements of foreign operations where the functional currency is different to the functional currency of the parent entity; and • Exchange differences arise on the translation of monetary items which form part of the net investment in the foreign operation.

Financial instruments [Abstract]
Financial instruments	Section 6. Financial instruments 6.1. Classification and measurement The carrying values of financial assets and liabilities of the Group approximate their fair value. The Group measures and recognizes in the statement of financial position on a recurring basis certain assets and liabilities at fair value in accordance with IFRS 13 Fair value measurement. The fair value must be estimated for recognition and measurement or for disclosure purposes in accordance with the following hierarchy: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2: Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices); and Level 3: Inputs for the asset or liabilities which are not based on observable market data (unobservable inputs). The Group has no financial assets where the carrying amount exceeds net fair values at balance date. The Group’s receivables at balance date are detailed in Section 4.2 of this report. 6.2. Financial risk management Framework The Group is involved in activities that expose it to a variety of financial risks including: a) Credit risk b) Liquidity risk c) Capital management risk d) Market risk related to commodity pricing, interest rates and currency fluctuations. The Board of Directors has overall responsibility for the establishment and oversight of the financial risk management framework of the Group. Management is responsible for monitoring the financial risks. The objective of the financial risk management strategy is to minimize the impact of volatility in financial markets on financial performance, cash flows and shareholder returns. This requires the identification and analysis of relevant financial risks and possible impact on the achievement of the Group’s objectives. The Group does not undertake any hedging activities. a) Credit risk Credit risk is the risk of sustaining a financial loss as a result of the default by a counterparty to make full and timely payments on transactions which have been executed, after allowing for setoffs which are legally enforceable. Credit risk arises from investments in cash and cash equivalents with banks and credit exposure to customers and/or suppliers. Receivables and cash and cash equivalents represent the Group’s maximum exposure to credit risk. There are no trade receivables past due or impaired at the end of the reporting period (2022: Nil b) Liquidity risk Liquidity risk is the risk that the Group will not have sufficient liquidity to meet its financial obligations as they fall due. The Group manages liquidity risk by continually monitoring forecast and actual cash flows and matching maturity profiles of financial assets and liabilities. Short and long-term cash flow projections are prepared periodically and submitted to the Board. Less than 1 year 1-2 years 2-5 years More than 5 years Total Contractual cash flows Note $’000 $’000 $’000 $’000 $’000 Consolidated – 2024 Payables 4.7 4,614 - - - 4,614 Lease Liabilities 4.7 41 29 13 - 83 Borrowings 4.8 1,200 - - - 1,200 Total 5,855 29 13 - 5,897 Consolidated – 2023 Payables 4.7 8,340 - - - 8,340 Lease Liabilities 4.7 138 38 43 - 219 Total 8,478 38 43 - 8,559 c) Capital management risk The overriding objective of the Group’s capital management strategy is to increase shareholder returns whilst maintaining the flexibility to pursue the strategic initiatives within a prudent capital structure. The primary objective of the capital management policy is to ensure the Group maintains a strong credit rating and appropriate capital ratios to support the development of the Company’s assets. The Company manages its capital structure and adjusts it in light of economic conditions. During the financial year the company undertook a capital raise through the issue of new shares. The Board believes that this capital raise secures the Company’s financial position until the ‘decision to mine’ stage of the Rhyolite Ridge Lithium-Boron Project. d) Market risk The method and assumptions remain consistent with prior periods. Foreign exchange risk Foreign exchange risk arises from the commercial transactions and valuations of assets and liabilities that are denominated in a currency that is not the entity’s functional currency. The Group has monetary items, including financial assets, denominated in currencies other than the functional currency of the entity. These are primarily US$ cash and intercompany loan balances in the holding company, which has an A$ functional currency. These items are restated to A$ equivalent at each period end, and the associated gain or loss is taken to the income statement. The US$ equivalent of these FX balances is reported in the group income statement as the functional currency financial statements are translated to US$ reporting currency for group reporting purposes. The Group operates in a predominantly USD environment. The majority of the Group’s financial position is managed and reported in US$. There is a foreign exchange exposure where the Group holds financial assets and liabilities in A$. These positions are summarised in the table below. Average rate for the Spot rate at the end of the Exchange rates applied during the year: AUD / USD 0.6557 0.6674 2024 2023 Financial instruments denominated in United States dollars US$’000 US$’000 Financial assets Cash 11,513 11,988 Trade and other receivables 105 103 Financial liabilities Trade and other payables (120 ) (857 ) Provisions - - Lease liabilities (251 ) (201 ) An increase in the AUD:USD foreign exchange rate of 10% would result in a: • $1,151,297 increase in A$ cash balance (June 30, 2023: $1,199,000) with nil impact on current year loss because the impact is taken to foreign currency translation reserve. • $10,492 increase in A$ receivables (June 30, 2023: $10,000) with nil impact on current year loss because the impact is taken to foreign currency translation reserve. • $11,981 increase in payables (June 30, 2023: $86,000) with nil impact on current year loss because the impact is taken to foreign currency translation reserve. • No change to lease liabilities (June 30, 2023: nil • $25,081 increase in provisions (June 30, 2023: $20,000) with nil impact on current year loss because the impact is taken to foreign currency translation reserve. A decrease in the AUD:USD foreign exchange rate of 10% would result in: • $1,151,297 decrease in A$ cash balance (June 30, 2023: $1,199,000) with nil impact on current year loss because the impact is taken to foreign currency translation reserve. • $10,492 decrease in A$ receivables (June 30, 2023: $10,000) with nil impact on current year loss because the impact is taken to foreign currency translation reserve. • $11,981 decrease in payables (June 30, 2023: $86,000) with nil impact on current year loss because the impact is taken to foreign currency translation reserve. • No change to lease liabilities (June 30, 2023: nil • $ 20,081 20,000 Interest rate risk The Company’s exposure to interest rate risk, which is the risk that a financial instrument’s value will fluctuate as a result of reasonable possible changes in the market interest rates arise in relation to the Company’s bank balances. The Company does not engage in any hedging or derivative transactions to manage interest rate risk. An increase of interest rates of 1% will result in a $308,000 (June 30, 2023: $687,000) decrease in the current year loss and an increase in interest income related to cash deposits. A decrease of interest rates of 1% will result in a $308,000 (June 30, 2023: $687,000) increase in current year loss and decrease in interest income related to cash deposits. Commodity price risk The Company is exposed to future commodity price risk. This risk arises from its activities directed at exploration and development of mineral commodities. If commodity prices fall, the share price for companies exploring for these commodities is affected. The Company does not hedge its exposures.

The Company has entered into indemnity deeds to indemnify executives of the Company against certain liabilities incurred in the course of performing their duties. 7.3. Share-based payments Share-based compensation is provided to employees via rights or options to acquire shares in the Company. As described in note 5.1 Share capital, the Company has two share schemes in operation. Under these plans, options or performance rights which may be converted into ordinary shares have been granted to non-executive directors, senior executives, employees and a number of consultants. The cost of these equity-settled transactions is determined by reference to the fair value at the date at which they are granted. The fair value of the options granted is determined using the Black & Scholes option pricing model. The fair value of the performance rights granted with time based hurdles is determined by using the 10 day Volume Weighted Average Price (VWAP) of the Company’s fully paid share capital, up to and including the date the performance rights are granted, and for the performance based performance rights the fair value is determined by using a Monte Carlo model for the valuation of the performance rights subject to the relative performance hurdle and for those rights subject to the business objectives, the valuation is equal to the value of the share price at grant date, multiplied by the number of shares anticipated to vest. The cumulative expense recognized for equity-settled transactions at each reporting date reflects: i. the extent to which the vesting period has expired, and ii. the number of awards that, in the opinion of the directors of the Company, will ultimately vest. This opinion is formed based on the best available information at balance date. Where an equity-settled award is cancelled, the estimate is treated as if it had vested on the date of cancellation, and any expense not yet recognized for the award is recognized immediately. Each plan is described in more detail below. Equity Incentive Plan – established at the 2018 AGM A new Equity Incentive Plan was established following the Annual General Meeting (AGM) held on October 31 2018. The purpose of the new Equity Incentive Plan (“the Plan”) is to provide eligible persons the opportunity to participate in the growth and profits of the Company and to attract, motivate and retain their services to promote the Company’s long-term success. Under the terms of the Plan, the Board may at its discretion invite eligible persons to participate in a grant of awards. An award may be either an option or performance right, to acquire a share in the capital of the Company in accordance with the Plan rules. Options and rights issued under the terms and condition of the new ioneer Equity Incentive Plan are as follows: Type Key terms Expiry Date Options Non-Executive Directors The options were issued at an exercise price equal to the VWAP for the Company’s shares over the 10 trading days immediately before the date of the AGM. The options vest after 12 months and expire 60 months from the date of issue. Tranche 1: Nov 9, 2023 Tranche 2: Nov 14, 2024 Performance rights – time-based Retention on Employment • Agreements with early recruits included vesting in equal instalments after 12 24 36 months 3 years • Conditional on the achievement of continuing employment N/A Deferred STI • 12 month • Conditional on the achievement of continuing employment N/A LTI grants • 36 month • Conditional on the achievement of continuing employment N/A Type Key terms Expiry Date Performance rights – performance-based LTI grants • 36 month • The Board will employ discretion in assessing Project results and determining vesting of performance units; below, at or above targets: o HSE: Top quartile HSE & Community performance (compared to North American Mining Projects) o Construction: Construction delivery compared to schedule at FID o Ops Readiness: Operational and business readiness on track (recruiting, systems, training etc.) o Cost Control: Project spend within margin established at FID o Share price: INR shareholder return compared to competitors • Unlike producing organizations with established operations that typically aim to deliver performance conditions tied to anticipated revenues, production levels and growth objectives, ioneer has a single pre-production project with less certainty or control over key deliverables. Providing the Board with the discretion to assess the extent of delivery, the importance/value of the various targets delivered (or not) allows the ability to balance shareholder expectations and KMP reward, motivation and retention. • The Board will employ discretion in assessing Project results and determining the vesting of performance units; below, at or above targets (up to 200 N/A Key features include: • The Board may at its discretion make invitations to or grant awards to eligible persons. • Award means an option or a performance right to acquire a Share in the capital of the Company. • Eligible Persons include executive directors or executive officers of the Group, employees, contractors or consultants of the group or any other person. • A participant may not sell or assign awards. • Within 30 days after the vesting date in respect of a vested performance right, the Company must either allocate shares or procure payment to the participant of a cash amount equal to the market price of the shares which would have otherwise been allocated. • At any time during the exercise period a participant may exercise any or all their vested options by paying the exercise price. Whilst there are a number of options and performance rights remaining on issue under the terms and conditions of previous schemes, no further options or rights will be issued under these pre-existing schemes which are described below. Share Option Plan The Group established a Share Option Plan in 2010 (and reconfirmed it at the 2016 AGM) to assist in the attraction, retention and motivation of KMP and in the retention of key consultants. Key features include: • Full or part time employees or consultants of the Group are eligible to participate. • Options issued pursuant to the plan will be issued free of charge. • Options are time based and there are no performance conditions. • Options cannot be transferred and are not quoted on the ASX. • Options expire if not exercised 90 days after a participant resigns from the Company. • The exercise price of the options, at grant date, shall be as the directors in their absolute discretion determine, provided the exercise price shall not be less than the weighted average of the last sale price of the Company’s shares on ASX at the close of business on each of the 5 business days immediately preceding the date on which the directors resolve to grant the options. • The directors may limit the total number of options which may be exercised under the plan in any year. A summary of options and performance rights on issue is set out in note 5.1.

Exploration license expenditure requirements In order to maintain the Company’s tenements in good standing with the various mines departments and comply with the underlying option agreements, the Company will be required to pay annual claim maintenance fees. It is likely that the granting of new licenses and changes in license areas at renewal or expiry will change the expenditure commitment to the Company from time to time. 9.2 Contingent liabilities Settlement of Rhyolite Ridge The Company entered an option agreement to purchase Rhyolite Ridge from Boundary Peak Minerals LLC on June 3, 2016. The Company has made 4 progress payments to Boundary Peak under the agreement. A final payment will fall due following Board making a ‘decision to mine’ the Rhyolite Ridge property. Once this decision is made, the Company is required under the terms of the contract to either: • Pay Boundary Peak LLC US$3 million, or • Issue shares (or a mix of both shares and cash) to Boundary Peak LLC, to the equivalent of US$3 million at a fixed exchange rate of USD $0.75 = AUD$1.00. At the date of this report the decision to mine has not yet been made by the Company. There are no other known contingent liabilities as at June 30, 2024. 9.3 Related Party disclosures Non-key management personnel disclosures The Group has a related party relationship with its controlled entities, refer to note 8.2. The Company and its controlled entities engage in a variety of related party transactions in the ordinary course of business. These transactions are conducted on normal terms and conditions. Key management personnel disclosures For all related party transactions with key management personnel, refer to note 7.2, Key management personnel disclosures. 9.4 Events after reporting date In the period since June 30, 2024 and up to the date of this report, there has not been any other item, transaction or event of a material and unusual nature likely in the opinion of directors, to substantially affect the operations of the Group, the results of those operations or the state of affairs of the Group in subsequent financial years.

Basis of preparation [Abstract]
Basis of preparation	1.2. Basis of preparation • These financial statements comply with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board ('IASB'), including new or amended accounting standards effective for reporting periods beginning July 1 2022. • Unless otherwise stated, the accounting policies disclosed have been consistently applied. • The financial report has been prepared on a historical cost basis. • The financial statements have been presented in US dollars which is the Groups presentation currency. • The financial statements have been prepared on the going concern basis which assumes the company and consolidated entity will have sufficient cash to pay its debts as and when they become payable for a period of at least 12 months from the date the financial report was authorised for issue.
New and amended accounting standards and interpretations	1.3. New and amended accounting standards and interpretations The Group has adopted all the new or amended Accounting Standards and Interpretations issued by the International Accounting Standards Board (“IASB”) that are mandatory for the current reporting period. Any new or amended Accounting Standards or Interpretations that are not yet mandatory have not been early adopted. The adoption of these Accounting Standards and Interpretations did not have any significant impact on the financial performance or position of the Group. The following standards and interpretations that have recently been issued but are not yet mandatory, have not been early adopted by the Group for the annual reporting period ended June 30, 2024. The Group’s assessment of the impact of these new or amended Accounting Standards and Interpretations, which are most relevant to the Group are set out below: Classification of Liabilities as Current or Non-current (IAS 1) A liability is classified as current if the entity has no right at the end of the reporting period to defer settlement for at least 12 months after the reporting period. The IASB issued amendments to IAS 1 Presentation of Financial Statements to clarify the requirements for classifying liabilities as current or non-current. Specifically: • The amendments specify that the conditions which exist at the end of the reporting period are those which will be used to determine if a right to defer settlement of a liability exists. • Management intention or expectation does not affect classification of liabilities. • In cases where an instrument with a conversion option is classified as a liability, the transfer of equity instruments would constitute settlement of the liability for the purpose of classifying it as current or non-current. These amendments had no material impact on the financial statements. Amendments to IAS 8 – Disclosure of Accounting Estimates The definition of a change in accounting estimates is replaced with a definition of accounting estimates. Under the new definition, accounting estimates are “monetary amounts in financial statements that are subject to measurement uncertainty”. Entities develop accounting estimates if accounting policies require items in financial statements to be measured in a way that involves measurement uncertainty. These amendments had no material impact on the financial statements. Amendments to IAS 12 - Deferred Tax related to Assets and Liabilities arising from a Single Transaction The initial recognition exemption has been narrowed such that it no longer applies to transactions that, on initial recognition, give rise to equal amounts of taxable and deductible temporary differences. These amendments had no material impact on the financial statements.
Basis of consolidation	1.4. Basis of consolidation Controlled entities Controlled entities are entities controlled by the Company. Control exists when the Company has the power, directly or indirectly to govern the financial and operating policies of an entity so as to obtain benefits from its operations. The financial statements of controlled entities are included in the consolidated financial statements from the date control commences until the date that control ceases. With the exception of the wind up of three Canadian entities during the financial year there has been no change in the control of any subsidiaries during the financial period. All subsidiaries are 100% owned by the Company (2023: 100%). Transactions eliminated on consolidation All inter-company balances and transactions, including unrealized profits arising from intra-group transactions, have been eliminated in full. Accounting policies The financial statements of subsidiaries are prepared for the same reporting period as the parent company, using consistent accounting policies.
Current versus non-current classification	1.5 Current versus non-current classification The Group presents assets and liabilities in the statement of financial position based on current/non-current classification. An asset is current when it is: - Expected to be realised or intended to be sold or consumed in the normal operating cycle - Held primarily for the purpose of trading - Expected to be realised within twelve months after the reporting period Or - Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period All other assets are classified as non-current. A liability is current when: - It is expected to be settled in the normal operating cycle - It is held primarily for the purpose of trading - It is due to be settled within twelve months after reporting period Or - There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period The terms of the liability that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification. The Group classifies all other liabilities as non-current. Deferred tax assets and liabilities are classified as non-current assets and liabilities.
Critical accounting estimates and judgements	1.6. Critical accounting estimates and judgements The preparation of these financial statements in conformity with International Financial Reporting Standards has required management to make judgements, estimates and assumptions which impact the application of policies and reported amounts of assets and liabilities, income and expenses. These estimates and associated assumptions are based on historical knowledge and various other factors that are believed to be reasonable in the circumstance. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed regularly and revisions to accounting estimates are reviewed in the period in which the estimate is revised. The most significant estimates and assumptions which have a significant risk of causing material adjustment to the carrying amounts of assets and liabilities within the next financial year relate to: Reserve estimates Reserves are estimates of the amount of product that can be economically and legally extracted, processed and sold from the Groups properties under current and foreseeable economic conditions. The group determines and reports reserves under the standards incorporated in the Australian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves, 2012 edition (the JORC code). The SEC generally requires disclosure of mining reserves in accordance with Regulation S-K, Subpart 1300. The determination of ore reserves includes estimates and assumptions about a range of geological, technical and economic factors including quantities, grades, production techniques, recovery rates, commodity prices and exchange rates. Change in ore reserve impact the assessment of recoverability of exploration and evaluation assets. Estimating the quantity and /or grade of reserves requires the size, shape and depth of ore to be determined by analyzing geological data. This process may require complex and difficult judgements to interpret the data. Exploration and evaluation assets The Group’s policy for exploration and evaluation expenditure is set out in note 4.6. The application of this policy requires certain judgements, estimates and assumptions as to the future events and circumstances, in particular the assessment of whether economic quantities of reserves will be found. Any such estimates and assumptions may change as new information becomes available. If, after capitalization of expenditure under the policy, it is concluded that the capitalized expenditure will not be recovered by future exploitation or sale, then the relevant amount will be written off in the statement of profit or loss. Changes in assumptions may result in a material adjustment to the carrying amount of exploration and evaluation assets. Share-based payment transactions The Group measures the cost of equity-settled transactions with employees by reference to the fair value of the equity investments at the date on which they are granted. Additional information is set out in note 7.3, Share-based payments.
Foreign Currency Transactions and Balances	1.7. Foreign Currency Transactions and Balances Functional and presentation currency The functional currency of each of the Group’s entities is measured using the currency of the primary economic environment in which that entity operates. The functional currency of the entities in the Group is predominantly US Dollars, with the exception of ioneer Limited, which has a functional currency of Australian Dollars. Transactions and balances Foreign currency transactions are translated at the foreign exchange rate at the date of the transaction. Monetary assets and liabilities denominated in a foreign currency at the end of the reporting period are translated at the year-end exchange rate. Exchange differences arising on the translation of monetary items are recognized in the statement of profit or loss. Non-monetary items measured at historical cost continue to be carried at the exchange rate at the date of the transaction. Exchange differences arising on the translation of non-monetary items are recognized directly in other comprehensive income to the extent that the underlying gain or loss is recognized in other comprehensive income; otherwise, the exchange difference is recognized in profit or loss. Presentation of foreign exchange gains and losses in the statement of profit or loss The Group presents its foreign exchange gains and losses within net financing income /expense in the statement of profit or loss.
