The Company does not consider that the Offers will have a material effect on the financial position of the Company. The expenses of the Offers will be met from the Company’s existing cash reserves.

Please refer to Section 5.10 for further details on the estimated expenses of the Offers.
What are the risks of a further investment in the Company? Potential investors should be aware that subscribing for Quoted Options in the Company involves a number of risks. The key risk factors of which investors should be aware are set out in Section 3, including (but not limited to) risks in respect of: • Future capital requirements: The Company has no operating revenue and is unlikely to generate any operating revenue unless and until its projects are successfully developed and production commences. The future capital requirements of the Company will depend on many factors including its business development activities. Should the Company require additional funding, there can be no assurance that additional financing will be available on acceptable terms or at all. Any inability to obtain additional financing, if required, would have a material adverse effect on the Company's business, financial condition and results of operations. • Title risk: The Company’s tenement portfolio is governed by the_Mining Act 1978_ (Cth), and related subsidiary legislation, which requires annual expenditure and/or reporting commitments, as well as other conditions requiring compliance. • Exploration and development risks: Mineral exploration and development are high-risk undertakings. There can be no assurance that exploration of acquired projects or any other exploration properties that may be acquired in the future will result in the discovery of an economic resource. Even if an apparently viable resource is identified, there is no guarantee that it can be economically exploited. • Operating risks: The operations of the Company may be affected by various factors, including failure to locate or identify mineral deposits, failure to achieve predicted grades in exploration and mining, operational and technical difficulties encountered in mining; difficulties in commissioning and operating plant and equipment, mechanical failure or plant breakdown, unanticipated metallurgical problems which may affect extraction costs; adverse weather conditions, industrial and environmental accidents, industrial disputes and unexpected shortages or increases in the costs of consumables, spare parts, plant and equipment. • Commodity price volatility: The Company's ability to proceed with the development of its rare earth, phosphate and niobium projects and benefit from any future mining operations will depend on market factors, some of which may be beyond its control. It is anticipated that any revenues derived from mining will primarily be derived from the sale of rare earths, phosphate and other minerals. Consequently, any future earnings are likely to be closely related to the price of this commodity and the terms of any off-take agreements that the Company enters into. • Native title and Aboriginal heritage risks:The_Native Title Act 1993_(Cth) recognises and protects the rights and interests in Australia of Aboriginal and Torres Strait Islander people in land and waters, according to their traditional laws and customs. There is significant uncertainty associated with native title in Australia and this may impact on the Company's operations and future plans by delaying, restricting or prohibiting access to tenements.	Section 3

Key Information

Further Information

• Environmental risks: Mining operations have inherent risks and liabilities associated with safety and damage to the environment and the disposal of waste products occurring as a result of mineral exploration and production. The occurrence of any such safety or environmental incident could delay production or increase production costs. Events, such as unpredictable rainfall or bushfires may impact on the Company’s ongoing compliance with environmental legislation, regulations and licences. Significant liabilities could be imposed on the Company for damages, clean-up costs or penalties in the event of certain discharges into the environment, environmental damage caused by previous operations or noncompliance with environmental laws or regulation. • Access, permits and approvals:In order to undertake mineral exploration on the Company’s tenements, the Company has various access deeds in place and will seek to implement others in key areas of the Company’s projects as and when it determines that activities should be undertaken. Certain mineral rights and interests to be held by the Company are subject to the need for ongoing or new government approvals and permits. These requirements, including work permits and environmental approvals, will change as the Company’s activities develop. Delays in obtaining, or the inability to obtain, required authorisations may significantly impact on the Company's operations. The Company’s capacity to undertake future mining operations in its Tenement area will be affected by various factors such as: (i) potential inability to obtain necessary consents and approvals to mine; (ii) delay to obtaining necessary consents and approvals to mine; (iii) increased costs in obtaining necessary consents and approvals to mine; and (iv) limited ground available for mining due to access restrictions and limitations. • Quotation risk:The Company will apply for quotation of the Quoted Options subject to compliance with the requirements of ASX and the Listing Rules. The Company makes no guarantee that any such application for quotation will be successful and there is a risk that the Company will not be able to satisfy the ASX requirements for quotation. In the event that the Company is unable to satisfy the ASX requirements, the Quoted Options will still be issued, but will be Unquoted Options and there will be no public market for the Quoted Options. If the Quoted Options are admitted to official quotation by ASX, the price of the Quoted Options is subject to uncertainty and there can be no assurance that an active market for the Quoted Options will develop or continue after the Offers. • Option risk and dilution:Options are, by their nature, only of value at times when the exercise price is lower than the price of the underlying Shares. There is no guarantee that the Quoted Options offered under this Prospectus will, at any particular time, have an exercise price which is lower than the price of the Shares. There is a risk that the Quoted Options may expire at a time when they have little or no value. On completion of the Offers, assuming the Offers are fully subscribed, there will be up to 106,818,181 Quoted Options on issue. If exercised, these Quoted Options will be converted into Shares, thereby causing the shareholdings of Shareholders to be diluted by up to 9.53% (on the basis that the Offers are fully subscribed and no other Securities are issued or exercised at the date of this Prospectus, other than the issues of Securities approved by Shareholders at the General Meeting as set out in Section 2.1). • General market risks: Share market conditions may affect the value of the Company's Securities regardless of the Company's operating performance.

Only May Placement Participants who participated in the May Placement and were issued May Placement Shares are eligible to participate in the May Placement Options Offer.

Based on the number of Shares issued under the May Placement, 61,363,636 Quoted Options may be issued under the May Placement Options Offer. No funds will be raised from the issue of the May Placement Options under this Prospectus.

Shares issued on exercise of the July Placement Options will rank equally with the Shares on issue at the Prospectus Date. Please refer to Section 4.1 for further information regarding the rights and liabilities attaching to the Shares.

1.4 Conditional Offers

The issue of the Quoted Options under the Offers is subject to ASX agreeing to grant Official Quotation of the Quoted Options on ASX by the time required under the Corporations Act (subject to compliance with the requirements of ASX and the Listing Rules for the quotation of a new class of securities).

As required by Listing Rule 2.5 condition 6, the Quoted Options to be issued under this Prospectus will only be admitted to Official Quotation by ASX if the conditions for quotation of a new class of securities are satisfied, which include (amongst other things):

• (i) there being a minimum of 100,000 Quoted Options on issue; and

• (ii) there being at least 50 holders with a marketable parcel (as defined in the Listing Rules).

If the Quoted Options to be issued under this Prospectus are not admitted to quotation within a period of three months from the Prospectus Date, any issue or transfer of Quoted Options in response to an Application made under this Prospectus will be void in accordance with section 723 of the Corporations Act and the Offers will not proceed. In such circumstances, the Company intends to proceed with the issue of these Quoted Options as Unquoted Options and there will be no public market for the Quoted Options.

1.5

Purpose of this Prospectus

Section 707(3) of the Corporations Act generally requires that a prospectus is issued in order for a person to whom securities were issued without disclosure under Part 6D of the Corporations Act to on-sell those securities within 12 months of the date of their issue.

The Corporations Act provides an exception to section 707(3) where an entity issues a ‘cleansing’ notice under section 708A(5). However, the Company is precluded from issuing a ‘cleansing’ notice in respect of the Quoted Options as they are not in a class of securities that were quoted securities at all times in the last 3 months.

Consequently, the Company has issued this Prospectus for the offers of the Quoted Options to May Placement Participants and July Placement Participants.

This Prospectus has also been issued to facilitate secondary trading of the Shares to be issued upon exercise of the Quoted Options to be issued under the Offers. Issuing the Quoted Options under this Prospectus will enable persons who are issued the Quoted Options to on-sell the Shares issued on exercise of the Quoted Options pursuant to ASIC Corporations (Sale Offers That Do Not Need Disclosure) Instrument 2016/80 .

Accordingly, the primary purpose of this Prospectus is to:

• (a) make the offers of Quoted Options under the May Placement Options Offer and the July Placement Options Offer; and

• (b) ensure that the on-sale of the Shares issued on conversion of the Quoted Options do not breach section 707(3) of the Corporations Act.

1.6

Opening and Closing Date

As set out in the Timetable, the Offers will open on 21 October 2025 ( Opening Date ) and are anticipated to close at 5.00pm (AWST) on 21 October 2025 ( Closing Date ).

8

The above dates are indicative only and subject to change without notice. The Company may vary these dates, including to close the Offers early, extend the Closing Date or to withdraw the Offers at any time prior to issue of the Quoted Options. If any of the dates are changed, subsequent dates may also change. You are encouraged to lodge your Application Form as soon as possible after the Opening Date.

The Company will accept Application Forms for the Offers from the Opening Date until 5.00pm (AWST) on the Closing Date or such other date as the Directors in their absolute discretion shall determine, subject to the requirements of the Listing Rules and the Corporations Act.

1.7 Minimum subscription

There is no minimum subscription under the Offers.

1.8 No underwriting

The Offers are not underwritten.

1.9

No rights trading

The rights to Quoted Options under the Offers are non-renounceable. Accordingly, there will be no trading of rights on ASX and you may not dispose of your right to receive some or all of the Quoted Options to any other party. If you do not take up your right to receive the relevant Quoted Options by the Closing Date, the offer to you will lapse.

1.10 Application Forms

Applications must be made using the relevant Application Form attached to or made available with a copy of this Prospectus. The Application Form must be completed in accordance with the instructions set out on the form. To the maximum extent permitted by law, the Directors will have discretion over which Applications to accept.

Completed Application Forms must be received by the Company prior to the Closing Date. Application Forms should be delivered in accordance with the instructions contained in the Application Form.

If the number of Quoted Options subscribed for under an Offer is more than the number of Quoted Options to which the Applicant is entitled under the Offer, the Company reserves the right to return the Application Form and not issue any Quoted Options to the Applicant or to accept it in respect of a lesser number of Quoted Options.

If you are in doubt as to the course of action, you should consult your professional advisor.

Acceptance of a completed Application Form by the Company creates a legally binding contract between the Applicant and the Company for the number of Quoted Options accepted by the Company. The Application Form does not need to be signed to be a binding acceptance of Quoted Options under an Offer. If the Application Form is not completed correctly it may still be treated as valid. The Directors’ decision as to whether to treat the acceptance as valid and how to construe, amend or complete the Application Form, is final.

By completing and returning an Application Form, Applicants will be deemed to have represented and warranted on behalf of themselves or each person on whose account they are acting, that the law in their place of residence and/or where they have been given the Prospectus does not prohibit them from being given the Prospectus and that they:

• (a) agree to be bound by the terms of the relevant Offer;

• (b) declare that all details and statements in the Application Form are complete and accurate;

• (c) declare that they are over 18 years of age and have full legal capacity and power to perform all their rights and obligations under the Application Form;

9

• (d) authorise the Company and its respective officers or agents, to do anything on their behalf necessary for the Quoted Options to be issued to them, including to act on instructions of the Company’s Share Registry upon using the contact details set out in the Application Form;

• (e) acknowledge that the information contained in, or accompanying, the Prospectus is not investment or financial product advice or a recommendation that Quoted Options are suitable for them given their investment objectives, financial situation or particular needs;

• (f) acknowledge that the Quoted Options have not, and will not be, registered under the securities laws in any other jurisdictions outside Australia; and

• (g) meet the eligibility criteria of the expected target market for the Quoted Options outlined in the TMD, a copy of which can be accessed at the Company’s website (https://rarex.com.au/).

1.11 Issue date and dispatch

The Quoted Options will be issued only after ASX has granted permission for the Quoted Options to be quoted. It is expected that Quoted Options will be issued and quoted by ASX in accordance with the dates specified in the Timetable.

It is the responsibility of Applicants to determine their allocation prior to trading in the Quoted Options. Applicants who sell Quoted Options before they receive their holding statements do so at their own risk.

1.12 ASX quotation

Application for quotation of the Quoted Options will be made to ASX in accordance with the Timetable.

The fact that ASX may grant Official Quotation of the Quoted Options is not to be taken in any way as an indication of the merits of the Company or the Quoted Options offered pursuant to this Prospectus. ASX takes no responsibility for the contents of this Prospectus.

1.13 CHESS

The Company participates in the Clearing House Electronic Sub-register System known as CHESS. ASX Settlement, a wholly owned subsidiary of ASX, operates CHESS in accordance with the Listing Rules and the ASX Settlement Operating Rules.

Under CHESS, Applicants will not receive a certificate but will receive a statement of their holding of Securities pursuant to their acceptance of an Offer.

Shareholders who are broker sponsored will receive a CHESS statement from ASX Settlement.

The CHESS statement will specify the number of Quoted Options issued under this Prospectus, provide details of your holder identification number, the participant identification number of the sponsor and the terms and conditions applicable to the Quoted Options.

If you are registered on the Issuer Sponsored sub-register, your statement will be despatched by the Share Registry and will contain the number of Quoted Options issued to you under this Prospectus and your security holder reference number.

A CHESS statement or Issuer Sponsored statement will routinely be sent to Security holders at the end of any calendar month during which the balance of their Security holding changes. Security holders may request a statement at any other time; however, a charge may be made for additional statements.

1.14 Residents outside Australia

The distribution of this Prospectus in jurisdictions outside Australia may be restricted by law and persons who come into possession of this Prospectus should observe any such restrictions, including those set forth below. Any failure to comply with such restrictions may constitute a violation of applicable securities laws.

This Prospectus, and any accompanying Application Form, do not, and is not intended to, constitute an offer of Quoted Options in any jurisdiction in which it would be unlawful. In particular, this Prospectus, and any accompanying Application Form, may not be distributed to any person, and the Quoted Options may not be offered or sold, in any country outside Australia except to the extent permitted below.

(a) Canada (British Columbia)

This document constitutes an offering of Quoted Options only in the Province of British Columbia (the “Province”), only to persons to whom Quoted Options may be lawfully distributed in the Province, and only by persons permitted to sell such securities. This document is not a prospectus, an advertisement or a public offering of securities in the Province. This document may only be distributed in the Province to investors that are “accredited investors” (as defined in National Instrument 45-106 – Prospectus Exemptions ).

No securities commission or authority in the Province has reviewed or in any way passed upon this document, the merits of the Quoted Options or the offering of the Quoted Options and any representation to the contrary is an offence.

No prospectus has been, or will be, filed in the Province with respect to the offering of Quoted Options or the resale of such securities. Any person in the Province lawfully participating in the Offers will not receive the information, legal rights or protections that would be afforded had a prospectus been filed and receipted by the securities regulator in the Province. Furthermore, any resale of the Quoted Options in the Province must be made in accordance with applicable Canadian securities laws. While such resale restrictions generally do not apply to a first trade in a security of a foreign, non-Canadian reporting issuer that is made through an exchange or market outside Canada, Canadian purchasers should seek legal advice prior to any resale of the Quoted Options.

The Company as well as its directors and officers may be located outside Canada and, as a result, it may not be possible for purchasers to effect service of process within Canada upon the Company or its directors or officers. All or a substantial portion of the assets of the Company and such persons may be located outside Canada and, as a result, it may not be possible to satisfy a judgment against the Company or such persons in Canada or to enforce a judgment obtained in Canadian courts against the Company or such persons outside Canada.

Statutory rights of action for damages and rescission. Securities legislation in the Province may provide a purchaser with remedies for rescission or damages if an offering memorandum contains a misrepresentation, provided the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s Province. A purchaser may refer to any applicable provision of the securities legislation of the purchaser’s Province for particulars of these rights or consult with a legal adviser.

Certain Canadian income tax considerations. Prospective purchasers of the Options should consult their own tax adviser with respect to any taxes payable in connection with the acquisition, holding or disposition of the Options as there are Canadian tax implications for investors in the Province.

Notes :

1. Subject to the satisfaction of various performance conditions and expiring on various dates between 10 February 2026 and 13 October 2028.

2. 108,500,000 Unquoted Options, comprising:

• (a) 33,000,000 Options exercisable at $0.018 and expiring on 27 December 2027; and

• (d) 15,000,000 Options exercisable at $0.025 each (which vest upon a Prospecting Licence for the Mrima Hill Project being granted to the Consortium) and expiring on 23 September 2028; and

• (e) 41,000,000 Options exercisable at $0.046 each and expiring on 13 October 2028.

• 3. Assumes that the Offers are fully subscribed, and no further Securities are issued, other than as set out below.

4. Assumes that the remaining 681,816 July Tranche 2 Placement Shares and the Director Placement Shares are issued (as approved by Shareholders at the General Meeting).

5. Assumes that the Joint Lead Manager Options are issued (as approved by Shareholders at the General Meeting ).

6. See Section 4.2 for the terms and conditions of the Quoted Options. The issue of the Quoted Options is conditional upon (amongst other things) ASX agreeing to grant Official Quotation of the Quoted Options on ASX by the time required under the Corporations Act (subject to compliance with the requirements of ASX and the Listing Rules for the quotation of a new class of securities). If this condition is not satisfied, then the Offers will not proceed. See Section 1.4 for further information.

14

2.2 Proposed use of funds

No funds will be raised from the issue of the Quoted Options under the May Placement Options Offer and July Placement Options Offer as the May Placement Options and July Placement Options are free-attaching to the May Placement Shares and July Placement Shares issued under the May Placement and July Placement, respectively.

The Company will receive $0.035 for each Quoted Option exercised. If all Quoted Options are issued and exercised, the Company will receive approximately $3,738,636 (before costs). There is no certainty that any of the Quoted Option will be exercised.

It is currently intended that funds raised from the May Placement and July Placement and any funds raised from the exercise of the Quoted Options will be applied towards:

• (a) advancing the procurement process for Mrima Hill, in consortium with Iluka Resources (ASX:ILU);

• (b) Cummins Range gallium definition, heritage agreements and monetisation studies;

• (c) exploration drilling at Mt Mansbridge HRE Khaleesi Nb, Gallium and Cummins Range near-mine anomalies;

• (d) general working capital; and

• (e) costs of the May Placement and July Placement.

The above is a statement of current intentions at the Prospectus Date. Intervening events and new circumstances have the potential to affect the manner in which the funds are ultimately applied. The Board reserves the right to alter the way the funds are applied on this basis.

The application of any funds from the exercise of Quoted Options will depend on when Quoted Options are exercised and the status of the Company’s projects and requirements at the relevant time.

2.3

Effect on control of the Company

The Company is of the view that the Offers will not affect the control (as defined by section 50AA of the Corporations Act) of the Company. No investor or existing Shareholder will have a voting power greater than 20% as a result of the completion of the Offers.

The maximum number of Quoted Options proposed to be issued under the Offers is 106,818,181. If all of these Quoted Options are exercised, the Shares issued on exercise will constitute approximately 9.53% of the Shares on issue following completion of the Offers (assuming the Offers and fully subscribed and no further Securities are issued or exercised at the date of this Prospectus, other than the issues of Securities approved by Shareholders at the General Meeting as set out in Section 2.1).

2.4 Substantial Shareholders

Based on the substantial shareholding notices that have been provided to the Company and ASX, no persons which together with their associates have a voting power in 5% or more of the Shares on issue.

2.5 Financial effect of the Offers

The Company does not consider that the Offers will have a material effect on the financial position of the Company.

2

If all Quoted Options are issued and exercised (which is not certain), it would have the effect on the Company's financial position of increasing the cash balance by approximately $3,738,636 (before costs).

The expenses of the Offers will be met from the Company’s existing cash reserves. The Offers will have an effect on the Company's financial position of reducing the cash balance by approximately $51,763. Please refer to Section 5.10 for further details on the estimated expenses of the Offers.

3. Risk factors

An investment in Quoted Options offered by this Prospectus should be regarded as speculative. Activities in the Company, as in any business, are subject to risks which may impact on the Company’s future performance. The Company has implemented appropriate strategies, actions, systems and safeguards for known risks, however some are outside its control.

The Directors consider that the following summary, which is not exhaustive, represents some of the major risk factors which prospective investors need to be aware of in evaluating the Company’s business and the risks of investing in the Company. Prospective investors should carefully consider the following factors in addition to the other information presented in the Prospectus.

The principal risks include, but are not limited to, the following:

3.1 Risks specific to the Company

(a) Future capital requirements

The Company does not have operating revenue and is unlikely to generate any operating revenue unless and until a project or projects are successfully developed and production commences. The future capital requirements of the Company will depend on many factors including its business development activities.

In order to successfully develop its projects and for production to commence, the Company will require further financing in the future. Any additional equity financing may be dilutive to Shareholders, may be undertaken at lower prices than the then market price or may involve restrictive covenants which limit the Company's operations and business strategy. Debt financing, if available, may involve restrictions on financing and operating activities.

No assurances can be made that appropriate capital or funding, if and when needed, will be available on terms favourable to the Company or at all. If the Company is unable to obtain additional financing as needed, it may be required to reduce the scope of its activities and this could have a material adverse effect on the Company's business, financial condition and results of operations.

The Company may undertake additional offerings of Securities in the future. The increase in the number of Shares issued and outstanding and the possibility of sales of such shares may have a depressive effect on the price of Shares. In addition, as a result of such additional Shares, the voting power of the Company's existing Shareholders will be diluted.

(b) New projects and acquisitions

The Company will actively pursue and assess other new business opportunities in the resources sector. These new business opportunities may take the form of direct project acquisitions, joint ventures, farm-ins, acquisition of tenements / permits, and/or direct equity participation.

The acquisition of projects (whether completed or not) may require the payment of monies (as a deposit and/or exclusivity fee) after only limited due diligence or prior to the completion of comprehensive due diligence. There can be no guarantee that any proposed acquisition will be completed or be successful. If the proposed acquisition is not completed, monies advanced may not be recoverable, which may have a material adverse effect on the Company.

If an acquisition is completed, the Directors will need to reassess at that time, the funding allocated to current projects and new projects, which may result in the Company reallocating funds from the projects and/or raising additional capital (if available).

4

Furthermore, notwithstanding that an acquisition may proceed upon the completion of due diligence, the usual risks associated with the new project / business activities will remain.

(c) Market risk

The Company currently maintains the following investments in listed companies as at the Prospectus Date:

• (i) 10,000,000 shares in the capital of Cosmos Exploration Limited (ASX: C1X);

• (ii) 4,498,333 shares in the capital of Kincora Copper Limited (ASX & TSXV: KCC); and

• (iii) 24,064,658 shares in the capital of Canada Rare Earth Corp. (TSXV: LL),

(together, the Investment Shares ).

The value of the Investment Shares is influenced by market factors, including, for example, changes in economic conditions, changes in interest rates and economic activity, changes to legislative and political environment as well as changes in investor sentiment.

In addition, exogeneous shocks, natural disasters, acts of terrorism and financial market turmoil such as the global financial crisis can add to the equity market volatility as well as impact directly on individual entities.

As a result, there is no guarantee that can be given in respect of the performance of the Company’s Investment Shares.

(d) Mrima Hill application risk

As announced to the ASX on 22 April 2025, the Company and Illuka Resources Limited (ASX: ILU) have entered into a consortium agreement to apply for the Mrima Hill rare earth-niobium-phosphate-manganese project licence in Kenya ( Mrima Hill or Mrima Hill Project ) ( Consortium Agreement ), and that the consortium has made a formal application to the National Mining Corporation of Kenya ( NAMICO ), which is aimed at securing approval to form a strategic partnership with NAMICO via a joint venture, into which the project licence ( Prospecting Licence ) will transfer ( Mrima Hill Application ). NAMICO has confirmed receipt of the application and is currently reviewing the proposal in parallel with the State Department for Mining.

At present, there are no guarantees that the consortium’s application for the Mrima Hill Project will be accepted and that the consortium will be invited to negotiate with NAMICO and the State Department for Mining the terms on which the proposed Prospecting Licence will be granted. The grant of the Prospecting Licence remains subject to discretion of NAMICO and the Cabinet Secretary and therefore investors are cautioned not to place undue reliance on the grant of the Prospecting Licence.

(e) Financing Agreement – GEM

As announced on 24 September 2025, the Company has executed a financing agreement with GEM Global Yield LLC SCS ( GEM ) under which GEM will make available funding of initially A$25 million in the form of a Share Subscription Facility ( SSF ), with a subsequent tranche made available if requested and if extension conditions are met ( Financing Agreement ). Funds will only be made available under the Financing Agreement if and when the Consortium is granted the Prospecting Licence for the Mrima Hill Project (refer to Section 3.1(d) for further details) and there is no guarantee that this condition will be satisfied.

5

The ability of the Company to utilise the funding to cover the Consortium’s year 1 – 3 work program will be subject to there being sufficient liquidity in the Company’s Shares to satisfy the drawdown requests in a timely manner. There are no guarantees that there will be sufficient liquidity in the Company’s Shares to satisfy the drawdown requests in full in the timeframes required to sole fund the year 1 – 3 work program.

(f)

Sovereign risk

Pursuant to the terms of the Consortium Agreement and subject to the Mrima Hill Application being successful, the Company will hold an interest in the Mrima Hill Project located in Kenya and will be subject to the risks associated in operating in a foreign country. These risks may include economic, social or political instability or change, hyperinflation, currency non-convertibility or instability and changes of law affecting foreign ownership, government participation, taxation, working conditions, rates of exchange, exchange control, exploration licensing, export duties, repatriation of income or return of capital, environmental protection, labour relations as well as government control over natural resources or government regulations that require the employment of local staff or contractors or require other benefits to be provided to local residents.

Any future material adverse changes in government policies or legislation in foreign jurisdictions in which the Company has projects that affect foreign ownership, exploration, development or activities of companies involved in exploration and production, may affect the viability and profitability of the Company.

(g)

Quotation risk

The Company will apply for quotation of the Quoted Options subject to compliance with the requirements of ASX and the Listing Rules, however, the Quoted Options will only be admitted to official quotation by ASX if the conditions for quotation of a new class of securities are satisfied (which include, amongst other things, there being a minimum of 100,000 Quoted Options on issue, with at least 50 holders with a marketable parcel (within the meaning of the Listing Rules)).

The Company makes no guarantee that any such application for quotation will be successful and there is a risk that the Company will not be able to satisfy the ASX requirements for quotation. In the event that the Company is unable to satisfy the ASX requirements, the Quoted Options will still be issued, but will be Unquoted Options and there will be no public market for the Quoted Options. If the Quoted Options are admitted to official quotation by ASX, the price of the Quoted Options is subject to uncertainty and there can be no assurance that an active market for the Quoted Options will develop or continue after the Offers.

(h) Option risk and dilution

Options are, by their nature, only of value at times when the exercise price is lower than the price of the underlying Shares. There is no guarantee that the Quoted Options offered under this Prospectus will, at any particular time, have an exercise price which is lower than the price of the Shares.

There is a risk that the Quoted Options may expire at a time when they have little or no value.

On completion of the Offers, assuming the Offers are fully subscribed, there will be up to 106,818,181 Quoted Options on issue. If exercised, these Quoted Options will be converted into Shares, thereby causing the shareholdings of Shareholders to be diluted by up to 9.53% (on the basis that the Offers are fully subscribed and no other Securities are issued or exercised at the date of this Prospectus, other than the issues of Securities approved by Shareholders at the General Meeting as set out in Section 2.1). However, each Quoted Option has an exercise price of $0.035 which means that the Company will receive additional funds of up to $3,738,636 (before costs) upon exercise

6

of the Quoted Options, assuming all Quoted Options the subject of the Offers are issued and subsequently exercised. There is no certainty that Quoted Options, if issued, will be exercised in full, or at all.

3.2 Mining industry risks

(a) Resource risks

There is inherent uncertainty with mineral resource and ore reserve estimates. Regardless of JORC Code or other status, there is a risk that actual mining performance will not deliver performance in line with mineral resource and ore reserve estimates.

(b) Exploration and development risks

Mineral exploration and development are high-risk undertakings. There can be no assurance that exploration of the projects or any other exploration properties that may be acquired in the future will result in the discovery of an economic resource. Exploration in terrains with existing mineralisation endowments and known occurrences may slightly mitigate this risk.

Even if an apparently viable resource is identified, there is no guarantee that it can be economically exploited due to various issues including lack of ongoing funding, adverse government policy, geological conditions, commodity prices or other technical difficulties.

The future exploration activities of the Company may be affected by a range of factors including geological conditions, limitations on activities due to seasonal weather patterns, unanticipated operational and technical difficulties, industrial and environmental accidents, native title process, changing government regulations and many other factors beyond the control of the Company.

The success of the Company will also depend upon the Company having access to sufficient development capital, being able to maintain title to its projects and obtaining all required approvals for its activities. In the event that exploration programs are unsuccessful this could lead to a diminution in the value of its projects, a reduction in the cash reserves of the Company and possible relinquishment of part or all of its projects.

(c) Native title and Aboriginal heritage risks

The Native Title Act 1993 (Cth) recognises and protects the rights and interests in Australia of Aboriginal and Torres Strait Islander people in land and waters, according to their traditional laws and customs. There is significant uncertainty associated with native title in Australia and this may impact on the Company's operations and future plans by delaying, restricting or prohibiting access to tenements.

(d)

Operating risk

The operations of the Company may be affected by various factors, including failure to locate or identify mineral deposits, failure to achieve predicted grades in exploration and mining, operational and technical difficulties encountered in mining; difficulties in commissioning and operating plant and equipment, mechanical failure or plant breakdown, unanticipated metallurgical problems which may affect extraction costs; adverse weather conditions, industrial and environmental accidents, industrial disputes and unexpected shortages or increases in the costs of consumables, spare parts, plant and equipment.

7

(e) Title risk

The Company’s tenement portfolio is governed by the Mining Act 1978 (WA), and related subsidiary legislation, which requires annual expenditure and/or reporting commitments, as well as other conditions requiring compliance. In order to mitigate risks associated with tenure, the Company designs exploration programs that will meet minimum expenditure requirements and advance the development of the tenements in a timely manner.

(f)

Access, permits and approvals

In order to undertake mineral exploration on the Company’s tenements, the Company has various access deeds in place and will seek to implement others in key areas of the Company’s projects as and when it determines that activities should be undertaken.

Certain mineral rights and interests to be held by the Company are subject to the need for ongoing or new government approvals and permits. These requirements, including work permits and environmental approvals, will change as the Company’s activities develop. Delays in obtaining, or the inability to obtain, required authorisations may significantly impact on the Company's operations. The Company’s capacity to undertake future mining operations in its Tenement area will be affected by various factors such as:

• (i) potential inability to obtain necessary consents and approvals to mine;

• (ii) delay to obtaining necessary consents and approvals to mine;

• (iii) increased costs in obtaining necessary consents and approvals to mine; and

• (iv) limited ground available for mining due to access restrictions and limitations.

• (g) Resources, reserves and exploration targets risk

Reserve and resource estimates are expressions of judgment based on knowledge, experience and industry practice. Estimates which were valid when initially calculated may alter significantly when new information or techniques become available. In addition, by their very nature resource and reserve estimates are imprecise and depend to some extent on interpretations which may prove to be inaccurate.

(h)

Metallurgy

Metal and/or mineral recoveries are dependent upon the metallurgical process, and by its nature contain elements of significant risk such as:

• (i) identifying a metallurgical process through test work to produce a saleable metal and/or concentrate;

• (ii) developing an economic process route to produce a metal and/or concentrate; and

• (iii) changes in mineralogy in the ore deposit can result in inconsistent metal recovery, affecting the economic viability of the project.

(i)

Regulatory compliance risk

The Company’s operating activities are subject to extensive laws and regulations relating to numerous matters including resource licence consent, environmental compliance and rehabilitation, taxation, employee relations, health and worker safety, waste disposal, protection of the environment, native title and heritage matters, protection of endangered and protected species and other matters. The Company requires permits from regulatory authorities to authorise the Company’s operations. These permits relate to exploration, development, production and rehabilitation

8

activities. Obtaining necessary permits can be a time-consuming process and there is a risk that Company will not obtain these permits on acceptable terms, in a timely manner or at all.

The costs and delays associated with obtaining necessary permits and complying with these permits and applicable laws and regulations could materially delay or restrict the Company from proceeding with the development of a project or the operation or development of a mine. Any failure to comply with applicable laws and regulations or permits, even if inadvertent, could result in material fines, penalties or other liabilities. In extreme cases, failure could result in suspension of the Company’s activities or forfeiture of its projects.

(j)

Land access risk

The Company’s rights in the tenements may be obtained by grant by regulatory authorities or be subject to contracts with third parties. The Company may lose its rights to exclusive use of, and access to any, or all, of the tenements.

Land access is critical for exploration and/or exploitation to succeed. It requires both access to the mineral rights and access to the surface rights. Mineral rights may be negotiated and acquired. In all cases the acquisition of prospective exploration and mining licences is a competitive business, in which proprietary knowledge or information is critical and the ability to negotiate satisfactory commercial arrangements with other parties is often essential. The Company may not be successful in acquiring or obtaining the necessary approvals or consents to conduct exploration or evaluation activities within or outside of the tenements. Additionally, the Company may not be able to access the tenements due to natural disasters or adverse weather conditions, political unrest, hostilities or failure to obtain the relevant approvals and consents.

(k)

Environmental risk

The operations and proposed activities of the Company are subject to environmental regulation under the laws in Australia. The costs of complying with these laws and regulations may impact the development of economically viable projects. As with most exploration projects and mining operations, the Company's activities are expected to have an impact on the environment, particularly if advanced exploration or field development proceeds. It is the Company's intention to conduct its activities to the highest standard of environmental obligation, including compliance with all environmental laws.

The cost and complexity of complying with the applicable environmental laws and regulations may prevent the Company from being able to develop potentially economically viable mineral deposits.

Although the Company believes that it is in compliance in all material respects with all applicable environmental laws and regulations, there are certain risks inherent to its activities, such as accidental spills, leakages or other unforeseen circumstances, which could subject the Company to extensive liability.

Government authorities may, from time to time, review the environmental bonds that are placed on permits. The Directors are not in a position to state whether a review is imminent or whether the outcome of such a review would be detrimental to the funding needs of the Company.

Further, the Company may require approval from the relevant authorities before it can undertake activities that are likely to impact the environment. Failure to obtain such approvals will prevent the Company from undertaking its desired activities. The Company is unable to predict the effect of additional environmental laws and regulations, which may be adopted in the future, including whether any such laws or regulations would materially increase the Company's cost of doing business or affect its operations in any area.

9

There can be no assurances that new environmental laws, regulations or stricter enforcement policies, once implemented, will not oblige the Company to incur significant expenses and undertake significant investments in such respect which could have a material adverse effect.

(l)

Commodity price volatility

The Company's ability to proceed with the development of its rare earth, phosphate and niobium projects and benefit from any future mining operations will depend on market factors, some of which may be beyond its control. It is anticipated that any revenues derived from mining will primarily be derived from the sale of rare earths, phosphate and other minerals. Consequently, any future earnings are likely to be closely related to the price of this commodity and the terms of any off-take agreements that the Company enters into.

The world market for rare earths is subject to many variables and may fluctuate markedly. These variables include world demand, forward selling by producers and production cost levels in major mineral-producing regions. Rare earth prices are also affected by macroeconomic factors such as general global economic conditions and expectations regarding inflation and interest rates, as well as geopolitics. These factors may have an adverse effect on the Company's exploration, development and production activities, as well as on its ability to fund those activities. The Company may undertake measures, where deemed necessary by the Board to mitigate such risks.

(m)

Joint venture risk

The medium to long term plans and strategies of the Company may evolve over time due to review, analysis and assessment of results from its planned exploration activities. This is consistent with other entities conducting mineral exploration similar to the Company.

As with most exploration entities, the Company may sell or dispose of its interests in any of its existing and future projects which are no longer of strategic importance to the Company and its objectives. Such a disposal may, for example, take the form of a tenement sale. The Company may also wish to develop its projects or future projects through joint venture or farm-in arrangements. Any joint ventures entered into by, or interests in joint ventures assigned to, the Company, could be affected by the default of any of the joint venture participants or their failure to act in the best interests of the joint venture, which in either case would likely have an adverse effect on the interests and prospects of the Company.

(n)

Third party risk

The operations of the Company will require involvement of a number of third parties, including suppliers. With respect to these third parties, and despite applying best practice in terms of precontracting due diligence, the Company is unable to completely avoid the risk of:

• (i) financial failure or default by a participant in any joint venture to which the Company may become a party; and

• (ii) insolvency, default on performance or delivery by any operators, contractors or service providers.

These contracts typically contain provisions providing for early termination of the contracts upon giving varying notice periods and paying varying termination amounts. The early termination of any of these contracts, for any reason, may mean that the Company will not realise the full value of the contract, which is likely to adversely affect the growth prospects, operating results and financial performance of the Company.

10

(o) Competition risk

The industry in which the Company will be involved is subject to domestic and global competition, including major mineral exploration and production companies. Although the Company will undertake all reasonable due diligence in its business decisions and operations, the Company will have no influence or control over the activities or actions of its competitors, which activities or actions may, positively or negatively, affect the operating and financial performance of the Company's projects and business.

Some of the Company's competitors have greater financial and other resources than the Company and, as a result, may be in a better position to compete for future business opportunities. Many of the Company's competitors not only explore for and produce minerals, but also carry out refining operations and other products on a worldwide basis. There can be no assurance that the Company can compete effectively with these companies.

(p) Reliance on key personnel

The Company will be reliant on a number of key personnel and consultants. The loss of one or more of these key contributors could have an adverse impact on the business of the Company.

It may be particularly difficult for the Company to attract and retain suitably qualified and experienced people given the current high demand in the industry and relatively small size of the Company, compared with other industry participants.

(q) Occupational health and safety

Exploration and production activities may expose the Company’s staff and contractors to potentially dangerous working environments. Occupational health and safety legislation and regulations differ in each jurisdiction. If any of the Company’s employees or contractors suffers injury or death, compensation payments or fines may be payable and such circumstances could result in the loss of a licence or permit required to carry on the business. Such an incident may also have an adverse effect on the Company’s business and reputation.

(r) Insurance

The Company intends to continue to insure its operations in accordance with industry practice. In certain circumstances, the Company’s insurance may not be of a nature or level to provide adequate insurance cover. The occurrence of an event that is not covered or fully covered by insurance could have a material adverse effect on the business, financial condition and results of the Company. Insurance against all risks associated with mining exploration and production is not always available and where available the costs can be prohibitive.

3.3 General risks

(a) Infectious diseases

The price of the Company’s Securities may be adversely affected by the economic uncertainty caused by infectious diseases. Measures to limit the transmission of infectious diseases implemented by governments around the world (such as travel bans and quarantining) may adversely impact the Company’s operations and may interrupt the Company carrying out its contractual obligations or cause disruptions to supply chains.

(b) Discretion in use of capital

The Board and the Company's management have discretion concerning the use of the Company's capital resources as well as the timing of expenditures. Capital resources

11

may be used in ways not previously anticipated or disclosed. The results and the effectiveness of the application of capital resources are uncertain. If they are not applied effectively, the Company's financial and/or operational performance may suffer.

(c)

Investment in capital markets

As with all stock market investments, there are risks associated with an investment in the Company. Securities listed on the stock market have experienced extreme price and volume fluctuations that have often been unrelated to the operating performances of such companies. These factors may materially affect the market price of Shares regardless of the Company's performance.

(d) General economic conditions

The operating and financial performance of the Company is influenced by a variety of general economic and business conditions, including levels of consumer spending, commodity prices, inflation, interest rates and exchange rates, supply and demand, industrial disruption, access to debt and capital markets and government fiscal, monetary and regulatory policies. Changes in general economic conditions may result from many factors including government policy, international economic conditions, significant acts of terrorism, hostilities or war or natural disasters. A prolonged deterioration in general economic conditions, including an increase in interest rates or a decrease in consumer and business demand, could be expected to have an adverse impact on the Company's operating and financial performance and financial position. The Company's future possible revenues and Share prices may be affected by these factors, which are beyond the control of the Company.

(e) Changes in government policies and legislation

Changes in government, monetary policies, taxation and other laws can have a significant impact on the Company’s assets, operations and ultimately the financial performance of the Company and its Shares. Such changes are likely to be beyond the control of the Company and may affect industry profitability as well as the Company’s capacity to explore and mine.

The Company is not aware of any reviews or changes that would affect its permits. However, changes in community attitudes on matters such as taxation, competition policy and environmental issues may bring about reviews and possibly changes in government policies. There is a risk that such changes may affect the Company’s development plans or its rights and obligations in respect of its permits. Any such government action may also require increased capital or operating expenditures and could prevent or delay certain operations by the Company the future performance of the Company or any return on an investment in the Company.

(f) Force majeure

The Company, now or in the future, may be adversely affected by risks outside the control of the Company including labour unrest, civil disorder, war, subversive activities or sabotage, extreme weather conditions, fires, floods, explosions or other catastrophes, epidemics, or quarantine restrictions.

(g) Unforeseen expenditure risk

Expenditure may need to be incurred that has not been taken into account in the preparation of this Prospectus. Although the Company is not aware of any such additional expenditure requirements, if such expenditure is subsequently incurred, this may adversely affect the expenditure proposals of the Company.

(h) Climate change risks

The climate change risks particularly attributable to the Company include:

12

• (i) the emergence of new or expanded regulations associated with the transitioning to a lower-carbon economy and market changes related to climate change mitigation. The Company may be impacted by changes to local or international compliance regulations related to climate change mitigation efforts, or by specific taxation or penalties for carbon emissions or environmental damage. These examples sit amongst an array of possible restraints on industry that may further impact the Company and its profitability. While the Company will endeavour to manage these risks and limit any consequential impacts, there can be no guarantee that the Company will not be impacted by these occurrences; and

• (ii) climate change may cause certain physical and environmental risks that cannot be predicted by the Company, including events such as increased severity of weather patterns and incidence of extreme weather events and longer-term physical risks such as shifting climate patterns. All these risks associated with climate change may significantly change the industry in which the Company operates.

(i) Taxation

The acquisition and disposal of Securities will have tax consequences, which will differ depending on the individual financial affairs of each investor. All potential investors in the Company are urged to obtain independent financial advice about the consequences of acquiring Securities from a taxation point of view and generally.

To the maximum extent permitted by law, the Company, its officers and each of their respective advisers accept no liability and responsibility with respect to the taxation consequences of applying for Securities under this Prospectus.

(j) Litigation risk

The Company is exposed to possible litigation risks including native title claims, tenure disputes, environmental claims, occupational health and safety claims and employee claims. Further, the Company may be involved in disputes with other parties in the future which may result in litigation. Any proven claim or dispute may adversely impact the Company's operations, financial performance and financial position. As at the date of this Prospectus, there are no material legal proceedings affecting the Company.

The above list of risk factors ought not to be taken as exhaustive of the risks faced by the Company or by investors in the Company.

The above factors, and others not specifically referred to above, may in the future materially affect the financial performance of the Company and the value of its Securities. Investors should consider that the investment in the Company is high risk and should consult their professional adviser before deciding whether to apply for Quoted Options pursuant to this Prospectus.

4. Rights attaching to Securities

4.1 Rights and liabilities attaching to Shares

A summary of the rights attaching to Shares in the Company is below. This summary is qualified by the full terms of the Constitution (a full copy of the Constitution is available from the Company on request free of charge) and does not purport to be exhaustive or to constitute a definitive statement of the rights and liabilities of Shareholders. These rights and liabilities can involve complex questions of law arising from an interaction of the Constitution with statutory and common law requirements. For a Shareholder to obtain a definitive assessment of the rights and liabilities which attach to Shares in any specific circumstances, the Shareholder should seek legal advice.

(a) General meetings

Shareholders are entitled to be present in person, or by proxy, attorney or representative to attend and vote at general meetings of the Company. Shareholders may requisition meetings in accordance with section 249D of the Corporations Act and the Constitution.

(b)

Voting rights

Subject to any rights or restrictions for the time being attached to any class or classes of Shares, at general meetings of Shareholders or classes of Shareholders:

• (i) each Shareholder entitled to vote may vote in person or by proxy, attorney or representative;

• (ii) on a show of hands, every person present who is a Shareholder or a proxy, attorney or representative of a Shareholder has one vote; and

• (iii) on a poll, every person present who is a Shareholder or a proxy, attorney or representative of a Shareholder will, in respect of each fully paid Share held by him, or in respect of which he is appointed a proxy, attorney or representative, have one vote for the Share, but in respect of partly paid Shares will have such number of votes as bears the same proportion to the total of such Shares registered in the Shareholder's name as the amount paid (not credited) bears to the total amounts paid and payable (excluding amounts credited).

(c)

Dividend rights

Subject to and in accordance with the Corporations Act, the Listing Rules, the rights of any preference Shareholders and to the rights of the holders of any shares created or raised under any special arrangement as to dividend, the Directors may from time to time declare a dividend to be paid to the Shareholders entitled to the dividend which will be payable on all Shares according to the proportion that the amount paid (not credited) is of the total amounts paid and payable (excluding amounts credited) in respect of such Shares.

No dividend will carry interest as against the Company.

The Company must not pay a dividend unless the Company’s assets exceed its liabilities immediately before the dividend is declared and the excess is sufficient for the payment of the dividend. The Directors may capitalise any profits of the Company and distribute that capital to the Shareholders, in the same proportions as the Shareholders are entitled to a distribution by dividend.

(d) Winding-up

If the Company is wound up, the liquidator may, with the authority of a special resolution of the Company, divide among the shareholders in kind the whole or any part of the

14

property of the Company, and may for that purpose set such value as the liquidator considers fair upon any property to be so divided, and may determine how the division is to be carried out as between the Shareholders or different classes of Shareholders.

(e) Further increase in capital

Subject to the Corporations Act and the Constitution, the Board may, on behalf of the Company, issue, grant options over or otherwise dispose of unissued shares to any person on the terms, with the rights, and at the times that the Board decides. The Company must not issue shares or grant options if the issue or grant would result in a breach of the Listing Rules.

(f)

Transfer of Shares

Shares can be transferred upon delivery of a proper instrument of transfer to the Company or by a transfer in accordance with the ASX Settlement Operating Rules. The instrument of transfer must be in writing, in any usual or common form or in any other form that the Directors approve.

Until the transferee has been registered, the transferor is deemed to remain the holder, even after signing the instrument of transfer.

In some circumstances, the Directors may refuse to register a transfer if upon registration the transferee will hold less than a marketable parcel. The Board may refuse to register a transfer of Shares upon which the Company has a lien. The Company must refuse to register a transfer of Shares where the Corporations Act, Listing Rules or ASX Settlement Operating Rules or a law about stamp duty requires the Company to do so.

(g) Variation of rights

Pursuant to section 246B of the Corporations Act, the Company may, with the sanction of a special resolution passed at a meeting of Shareholders vary or abrogate the rights attaching to shares.

If at any time the share capital is divided into different classes of shares, the rights attached to any class (unless otherwise provided by the terms of issue of the shares of that class), whether or not the Company is being wound up, may be varied or abrogated with the consent in writing of the holders of three-quarters of the issued shares of that class, or if authorised by a special resolution passed at a separate meeting of the holders of the shares of that class.

(h) Alteration of Constitution

The Constitution can only be amended by a special resolution passed by at least three quarters of Shareholders present and voting at the general meeting. In addition, at least 28 days written notice specifying the intention to propose the resolution as a special resolution must be given.
