Share Purchase Plan


•       Share Purchase Plan to provide eligible shareholders with the opportunity to subscribe for new Shares in
        parcels starting from A$170 (or approximately ZAR2,000)1 up to a maximum of A$30,000 (approximately
        ZAR355,000)2 at an issue price of 1.1 cents per Share (or ZAR13 cents) 1. This will provide eligible existing
        shareholders with the opportunity to participate in the capital raise at the same offer price as the Shares
        issued under the Placement.

•       Funds raised from the Placement and Share Purchase Plan to be used principally to partially fund the
        development of the Upper at the Prieska Copper Zinc Mine (PCZM), including ongoing dewatering and
        site works; for mine development optimisation studies and ongoing site works at the Okiep Copper
        Project; and for general working capital purposes, including work associated with finalisation of off-take
        related funding for the development of the PCZM.

Orion Minerals Limited (ASX/JSE: ORN) (Orion or the Company) announced on 8 July 2025 that it has secured
firm commitments for a Placement of new fully paid ordinary shares (Shares) to sophisticated and professional
investors (Placement) and agreement to convert outstanding loan amounts owed by Orion to equity for a
total aggregate value of ~A$5.8 million (~ZAR67 million)3. Approximately 522 million Shares will be issued under
the Placement and loan conversions, at an issue price (or deemed issue price, as applicable) of 1.1 cents per
Share (ZAR13 cents) (Placement Price).

Orion also announced that it is undertaking a share purchase plan to raise approximately A$4 million (~ZAR46
million) (SPP), providing shareholders an opportunity to increase their shareholding in Orion at the same price
as the Placement Price.

Under the SPP, the Company is offering existing eligible shareholders, being those shareholders with a
registered address in Australia, New Zealand, South Africa, the European Union (Germany and Netherlands),
Jersey (Channel Islands), United Kingdom, Mauritius and Singapore that held Orion shares as at 7.00pm
(Melbourne time) on 7 July 2025 (Record Date) (Eligible Shareholders), the opportunity to purchase Shares
under the SPP.

Purpose of the SPP

The SPP offer will give Eligible Shareholders the opportunity to participate in the Company's capital raising at
the same offer price as the Shares issued under the Placement.

Orion intends to apply the funds raised from the Placement and SPP, principally:

    •   to partially fund the development of the Upper of the Prieska Copper Zinc Mine (PCZM), including the
        ongoing dewatering and site works;

    •   for mine development optimisation studies and ongoing site works at the Okiep Copper Project; and

1 Based on an AUD:ZAR exchange rate of ~11.8.
2 Based on the A$:ZAR exchange rate of approximately 11.8. If you apply in ZAR, the maximum value of New Shares for which you will be able to
apply (being A$30,000) will be determined by reference to the A$:ZAR exchange rate published by Oanda on its website at 7:00pm Melbourne
time on the business day prior to the Closing Date (as that term is defined below).
3 Based on an A$:ZAR exchange rate of approximately 11.5 as at the date of announcement of the Placement.

  •      for general working capital purposes, including work associated with the finalisation of off-take related
         funding for the development of the PCZM.

Details of the SPP

The SPP will open today and is expected to close on Tuesday, 5 August 2025.

Under the SPP, each Eligible Shareholder will be entitled to apply for parcels of new Shares from a minimum
parcel of A$170 (or ZAR2,000) up to a maximum of A$30,000 (or ZAR355,000) without incurring brokerage or
transaction costs. The issue price per Share under the SPP will be 1.1 cents per Share (being ZAR13 cents),
being the same price paid by investors under the Placement (see above). This represents an 8.3% discount to
the 3 July 2025 closing price of the Company's Shares trading on the ASX and a 13.3% discount to the 3 July
2025 closing price of the Company's Shares trading on the Johannesburg Stock Exchange (JSE).

The Company will issue up to ~363.64 million SPP Shares under the SPP at an issue price of 1.1 cents per Share
(ZAR13 cents). The Company is seeking to raise approximately A$4.0 million (or ~ZAR46 million) from the issue
of SPP Shares. The Company, however, reserves the absolute discretion to determine the final amount raised
under the SPP and may accept over subscriptions or scale back any application at the Board's discretion.
Without limiting the Board's discretion, the Board may have regard to the application size of individual
applicants.

All SPP Shares will be quoted on either the ASX or JSE (for South African Eligible Shareholders) and will rank
equally with other fully paid ordinary shares on issue. The SPP Shares will be issued in accordance with ASX
Listing Rule 7.2, exception 5 and will not utilise the Company's placement capacity under ASX Listing Rule 7.1.
No shareholder approval is necessary in respect of the Shares issued under the terms of the SPP.

A copy of the SPP booklet containing further details of the SPP and Application Form is attached to this
announcement and is in the process of being dispatched to Eligible Shareholders. Key dates of the SPP are
set out in the timetable below. Eligible Shareholders should read the SPP booklet before deciding whether to

CHAIRMAN'S LETTER

15 July 2025

Dear Shareholder,

Invitation to Participate in Orion Minerals Ltd Share Purchase Plan
On 8 July 2025, Orion Minerals Ltd ACN 098 939 274 (Orion or Company) announced that it is undertaking a
capital raising.

The capital raising is being conducted via a placement to sophisticated and professional investors pursuant to
Section 708 of the Corporations Act 2001 (Corporations Act) to raise approximately A$3.3 million (~ZAR37 million)1
(Placement) and comprises the issue of approximately 289 million fully paid ordinary shares (Shares) in the
Company at an issue price of A$0.011 (being ZAR0.13)2 per Share.

Orion also announced that it would undertake a share purchase plan offer of Shares in the Company to eligible
existing shareholders to raise up to A$4.0 million (Share Purchase Plan or Offer) in connection with the Placement.
On behalf of the board of directors of the Company (Board), I am pleased to offer you, as an Eligible Shareholder
(as that term is defined below), the opportunity to participate in the Share Purchase Plan. The Share Purchase
Plan allows you to apply to purchase up to A$30,000 (approximately ZAR355,000)3 worth of Shares (New Shares)
(subject to scale back at Orion's absolute discretion) without brokerage or other transaction costs. Please give
your urgent attention to this Offer as it closes at 7:00pm (Melbourne time) and 10:00am (South African time) on
Tuesday, 5 August 2025.

The Share Purchase Plan has been designed to allow Eligible Shareholders to subscribe for New Shares from a
minimum application amount of A$170 (approximately ZAR2,000)4, up to a maximum of A$30,000
(approximately ZAR355,000) per shareholder, at the same offer price as the Shares under the Placement, without
having to pay brokerage or other costs that would normally apply to an on-market purchase of Shares. The Offer
applies irrespective of the number of Shares currently held by the Eligible Shareholder.

The amount proposed to be raised under the Share Purchase Plan is A$4.0 million (~ZAR46 million)5 (SPP Amount).
The Company, however, reserves the absolute discretion to determine the final amount raised under the Share
Purchase Plan and may accept over subscriptions or scale back any application at the Board's absolute
discretion. Without limiting the Board's discretion, the Board may have regard to the applicant's shareholding
when determining and applying any scale-back.

The proceeds of the Share Purchase Plan will be used by Orion principally:

    1.    to partially fund the development of the Upper of the Prieska Copper Zinc Mine (PCZM), including the
          ongoing mine dewatering and site works;

    2.    for mine development optimisation studies and ongoing site works at the Okiep Copper Project; and

    3.    for general working capital purposes, including work associated with the finalisation of off-take related
          funding for the development of the PCZM.

The Share Purchase Plan provides the opportunity to increase your investment in Orion at an issue price of
A$0.011 (or ZAR0.13) per New Share (SPP Price), which represents a:

    •    8.3% discount to the 3 July 2025 closing price of the Company's Shares trading on the Australian Securities
         Exchange (ASX); and

    •    13.3% discount to the 3 July 2025 closing price of the Company's Shares trading on the Johannesburg
         Stock Exchange (JSE).

1 Based on an A$:ZAR exchange rate of approximately 11.5 as at the date of announcement of the Placement.
2 Based on an A$:ZAR exchange rate of approximately 11.8.
3 Based on the A$:ZAR exchange rate of approximately 11.8. If you apply in ZAR, the maximum value of New Shares for which you will
be able to apply (being A$30,000) will be determined by reference to the A$:ZAR exchange rate published by Oanda on its website
at 7:00pm Melbourne time on the business day prior to the Closing Date (as that term is defined below).
4 Based on an A$:ZAR exchange rate of approximately 11.5.
5 Based on an A$:ZAR exchange rate of approximately 11.5.

The Share Purchase Plan also provides an opportunity to any existing Eligible Shareholder holding an
unmarketable parcel of Shares on the ASX (being less than A$500 worth of Shares) to increase their holdings
without incurring transaction costs.

Participation in the Share Purchase Plan is optional and is open exclusively to shareholders of the Company in
Australia, South Africa, New Zealand, the European Union (Germany and Netherlands), Jersey (Channel Islands),
Mauritius, Singapore and the United Kingdom who were holders of Shares at 7:00pm (Melbourne time) on
Monday, 7 July 2025 (Record Date) (Eligible Shareholder).

The Offer is personal to you and is non-renounceable and cannot be transferred to another person.

The Offer of New Shares under this Share Purchase Plan is made in accordance with ASIC Corporations (Share
and Interest Purchase Plans) Instrument 2019/547 (ASIC Instrument) and therefore does not require a prospectus
for the purposes of Chapter 6D of the Corporations Act.

Important information regarding potential Scale-back in the Share Purchase Plan

    •    The Share Purchase Plan is intended to raise up to the SPP Amount and entitles Eligible Shareholders,
         irrespective of the size of their shareholding, to purchase up to A$30,000 (approximately ZAR355,000)
         worth of New Shares at the SPP Price. If subscriptions received by Orion under the Share Purchase Plan
         exceed the SPP Amount, or such other amount determined by the Board, Orion may elect to scale
         back the maximum number of New Shares issued to each shareholder to the extent and in the manner
         that it sees fit in its absolute discretion (Scale-back). Without limiting the Company's discretion to scale
         back applications, if you apply for a ZAR amount of New Shares and the exchange rate varies such
         that the dollar amount you applied for exceeds A$30,000 (being the maximum limit under the ASIC
         Instrument), New Shares having a total issue price equal to A$30,000 will be issued to you and you will
         be refunded the excess cash amount (without interest).

    •    You may be allocated New Shares to a value which is significantly less than the parcel which you
         applied for and the difference will be refunded to you without any interest.

    •    Orion may Scale-back the maximum number of New Shares issued to each shareholder in its absolute
         discretion. Without limiting the Board's discretion, the Board may have regard to the applicant's
         shareholding when determining and applying any Scale-back.

    •    Should a shareholder be Scaled-back, the excess application monies will be refunded to the
         shareholder without interest.

    •    Shareholders should keep this potential Scale-back in mind when deciding how much to apply for
         under the Share Purchase Plan.


Important information regarding the maximum limit of A$30,000

     •   Under the ASIC Instrument, the maximum amount an Eligible Shareholder may subscribe for under a
         share purchase plan (or any similar arrangement) in any consecutive 12 month period is A$30,000.

     •   To ensure compliance with this requirement, Eligible Shareholders will be asked to certify in their
         Application Form that, as at the Issue Date under the Share Purchase Plan (expected to be on or
         around Tuesday, 12 August 2025), the total application price for New Shares issued to them under the
         Share Purchase Plan or any similar arrangement in the preceding 12 months does not exceed
         A$30,000 (approximately ZAR355,000).

     •   Eligible Shareholders should take this into account when applying for New Shares under the Share
         Purchase Plan, noting that Shares issued under Orion's 2024 Share Purchase Plan (on 30 July 2024) will
         fall outside the relevant 12-month period and will not be counted towards the A$30,000 limit for this
         Share Purchase Plan.

How to apply

If you are an Eligible Shareholder and wish to participate in the Share Purchase Plan, you may apply to purchase
New Shares up to a maximum of A$30,000 (approximately ZAR355,000) at the SPP Price. The minimum
application amount is A$170 (approximately ZAR2,000).

For non-South African resident Eligible Shareholders, you can apply by either:

    •    completing the application form for the Offer (Application Form) available to download from
         https://events.miraqle.com/orn-spp and making payment in accordance with the details on the
         Application Form; or

    •    making payment directly by BPAY® in accordance with the details on the Application Form.

BPAY® payments must be made from an Australian dollar account of an Australian financial institution.

For South African resident Eligible Shareholders, you can apply by:

      •   completing the enclosed Application Form as instructed and returning it to the address indicated on
          the form; and

      •   making payment in accordance with the details on the Application Form.

Your application and payment must be received by 7:00pm (Melbourne time) and 10:00am (South African time)
on Tuesday, 5 August 2025 (Closing Date).

Raising Amount and Scale-back

The amount proposed to be raised under the Share Purchase Plan is A$4.0 million (~ZAR46 million). The Board,
however, reserves the absolute discretion to determine the final amount raised under the Share Purchase Plan.

The Board may in its discretion accept oversubscriptions above this amount, subject to compliance with the ASX
Listing Rules (including that the number of New Shares issued under the Share Purchase Plan does not exceed
30% of the number of Shares currently on issue) and the ASIC Instrument.

The Board may also in its discretion undertake a Scale-back. When applying under the Share Purchase Plan,
please be aware of the potential for a Scale-back as it may impact the number of New Shares you receive. If
there is a Scale-back, your application monies may be greater than the value of the New Shares you will be
issued. In such event, the excess application monies will be refunded to you without interest.

For example, if you apply for A$20,000 of New Shares and Orion scales back your allocation to A$16,000 of New
Shares (rounded down to the nearest whole number of New Shares), you will receive a refund of A$4,000 without
interest.

                              Dispatch of holding statements (ASX)                  Wednesday, 13 August 2025

                             The timetable is indicative only and Orion may vary any of the above dates in its
                             absolute discretion at any time, subject to the Corporations Act, the ASX Listing
                             Rules and other applicable laws, by lodging a revised timetable with the ASX and
                             JSE. Orion reserves the right to close the Share Purchase Plan early, accept late
                             applications or extend the Closing Date in its sole and absolute discretion, should it
                             be considered necessary to do so, by making an announcement to ASX. The
                             commencement of trading and quotation of Shares offered under the Share
                             Purchase Plan is subject to confirmation from ASX.

5.    How much can I         If you are an Eligible Shareholder and wish to participate in the Share Purchase Plan,
      invest?                you may apply to purchase New Shares up to a maximum of A$30,000
                             (approximately ZAR355,000) at the SPP Price, with the minimum application amount
                             being A$170 (approximately ZAR2,000).

                             Each Eligible Shareholder may only acquire a maximum of A$30,000 (approximately
                             ZAR355,000) worth of New Shares under the Share Purchase Plan, irrespective of the
                             number of Shares they currently hold. This limitation applies even if you receive more
                             than one Application Form, or if you hold Shares in more than one capacity.

                             To ensure compliance with this requirement, Eligible Shareholders will be asked to
                             certify in their Application Form that, as at the Issue Date under the Share Purchase
                             Plan (expected to be on or around Tuesday, 12 August 2025), the total application
                             price for New Shares issued to them under the Share Purchase Plan or any similar
                             arrangement in the preceding 12 months does not exceed A$30,000 (approximately
                             ZAR355,000). Eligible Shareholders should take this into account when applying for
                             New Shares under the Share Purchase Plan, noting that Shares issued under Orion's
                             2024 Share Purchase Plan (on 30 July 2024) will fall outside the relevant 12-month
                             period and will not be counted towards the A$30,000 limit for this Share Purchase
                             Plan.

                             The minimum application amount is A$170 (approximately ZAR2,000).

                             The maximum application amount is A$30,000 (approximately ZAR355,000).

                             The maximum application amount above is an Australian dollar amount. If you apply
                             for a ZAR amount of New Shares, Orion will convert the ZAR amount to an Australian
                             dollar amount at the A$:ZAR exchange rate published by Oanda on its website at
                             7:00pm (Melbourne time) on the business day prior to the Closing Date.

                             If you apply for a ZAR amount of New Shares and the exchange rate varies such
                             that the dollar amount you applied for exceeds A$30,000 (being the maximum limit
                             under the ASIC Instrument), New Shares having a total issue price equal to A$30,000
                             will be issued to you and you will be refunded the excess cash amount (without
                             interest).

                                   holding beneficial interests in such Shares.

     OTHER TERMS AND CONDITIONS

     IMPORTANT NOTICE

     If you apply to participate in the Share Purchase Plan, you should be aware, and accept the risk, that the market
     price of Shares may change between the date of the Share Purchase Plan offer and the date when New Shares
     are issued to you under the Share Purchase Plan. As such, it is possible that, up to or after the date you receive
     New Shares under the Share Purchase Plan, you may be able to buy Shares on the ASX/JSE at a lower price than
     under the Share Purchase Plan. We encourage you to seek your own professional advice regarding your
     participation in the Share Purchase Plan.

     By returning an Application Form or submitting your payment via BPAY® for New Shares under the Share Purchase
     Plan, you certify and represent to the Company that, as at the Issue Date under the Share Purchase Plan
     (expected to be on or around Tuesday, 12 August 2025), the total of the application price for New Shares or
     Shares under current and previous plan purchases (as that term is defined below) is not more than A$30,000
     (approximately ZAR355,000). Eligible Shareholders should take this into account when applying for New Shares
     under the Share Purchase Plan, noting that Shares issued under Orion's 2024 Share Purchase Plan (on 30 July
     2024) will fall outside the relevant 12-month period and will not be counted towards the A$30,000 limit for this
     Share Purchase Plan.

(v)    you agree not to send any materials relating to the Share Purchase Plan to any person in the
       United States or a person acting on the account of a person in the United States;

(w)    you agree that if in the future you decide to sell or otherwise transfer the New Shares you will only
       do so in "regular way" transactions on the ASX or the JSE where neither you nor any person acting
       on your behalf knows, or has reason to know, that the sale has been pre-arranged with, or that
       the purchaser is, in the United States;

(x)    you agree to be bound by the constitution of Orion (as amended from time to time);

(y)    you acknowledge that none of Orion, its advisors, its agents, the ASX Registry or JSE Registry has
       provided you with investment advice or financial product advice, and that none of them has
       any obligation to provide this advice, concerning your decision to apply for and buy New Shares,
       and that this Booklet has been prepared without taking into account the objects, financial
       situation, tax position or needs of individuals;

(z)    you declare that you are at least 18 years of age and have full legal capacity and power to
       perform all your rights and obligations in respect of the Offer; and

(aa)   you are aware, and accept the risk, that the market price of Shares may change between the
       date of the Share Purchase Plan offer and the date when New Shares are issued to you under
       the Share Purchase Plan, and that the SPP Price may exceed the market price of Shares on the
       Issue Date.

2.    Joint holders / multiple holdings

       If you are a joint holder of Shares, you are taken to be a single registered holder of Shares for the purposes
       of determining whether you are an Eligible Shareholder and joint holders are entitled to participate in
       the Share Purchase Plan in respect of that single holding only. If, as a joint holder, you receive more than
       one offer under the Share Purchase Plan due to multiple registered holdings, you may still only apply for
       one maximum parcel of A$30,000 worth of New Shares in aggregate.

3.    Custodians

3.1    Eligible Shareholders who hold Shares as a "custodian" (as defined in the ASIC Instrument) (Custodian)
       may participate in the Share Purchase Plan on behalf of one or more persons whom the Custodian holds
       Shares on behalf of (Custodian Beneficiaries). If a Custodian applies for New Shares on behalf of a
       Custodian Beneficiary, Orion may not issue New Shares to the Custodian under the Share Purchase Plan
       with a total application price exceeding A$30,000 (approximately ZAR355,000) in any 12-month period
       unless the Custodian certifies the following in writing to Orion:

       (a)    either or both of the following:

              (i)      that the Custodian holds the Shares on behalf of one or more persons that are not
                       custodians (Participating Beneficiaries); or

              (ii)     that another custodian (Downstream Custodian) holds beneficial interests in Shares on
                       behalf of a Participating Beneficiary, and the Custodian holds the Shares to which those
                       beneficial interests relate on behalf of the Downstream Custodian or another custodian,
             on the Record Date and that each Participating Beneficiary has subsequently instructed the
             following persons to apply for New Shares under the Share Purchase Plan on their behalf:

             (iii)   where sub-paragraph (a)(i) applies – the Custodian; and

             (iv)    where sub-paragraph (a)(ii) applies – the Downstream Custodian;

      (b)    the number of Participating Beneficiaries;

      (c)    the name and address of each Participating Beneficiary, and that each Participating
             Beneficiary's address is located in Australia, South Africa, New Zealand, the European Union
             (Germany and Netherlands), Jersey (Channel Islands), Mauritius, Singapore or the United
             Kingdom;

      (d)    that each Custodian Beneficiary is not in the United States, or a person acting for the account or
             benefit of a person in the United States and that the Custodian has not sent any materials relating
             to the Share Purchase Plan to any person in the United States;

      (e)    in respect of each Participating Beneficiary:

             (i)     where sub-paragraph (a)(i) applies – the number of Shares that the Custodian holds on
                     their behalf and the number or dollar amount of New Shares they instructed the
                     Custodian to apply for on their behalf; and

             (ii)    where sub-paragraph (a)(ii) applies – the number of Shares to which the beneficial
                     interests relate and the number or dollar amount of New Shares they instructed the
                     Downstream Custodian to apply for on their behalf;

      (f)    as at the Issue Date under the Share Purchase Plan (expected to be on or about Tuesday, 12
             August 2025), there are no Participating Beneficiaries in respect of which the total of the
             application price for the following exceeds A$30,000 (approximately ZAR355,000):

             (i)     the New Shares applied for by the Custodian under the Share Purchase Plan in
                     accordance with the instructions referred to in sub-paragraph (e); and

             (ii)    any other Shares issued to the Custodian in the previous 12 months as a result of an
                     instruction given by them to the Custodian or the Downstream Custodian to apply for
                     Shares on their behalf under an arrangement similar to the Share Purchase Plan;

      (g)    that a copy of this Booklet was given to each Participating Beneficiary; and

      (h)    where sub-paragraph (a)(ii) applies – the name and address of each Custodian who holds
             beneficial interests in the Shares held by the Custodian in relation to each Participating
             Beneficiary,

      (Custodian Certificate).

3.2   Custodians must request a Custodian Certificate template when making an application on behalf of
      Custodian Beneficiaries. To request a Custodian Certificate template or for further information about the
      custodian application process, a Custodian should contact Orion on +61 3 8080 7170 (Australia) or
      0861472644 (local South Africa) and +27 11 0290112 (international South Africa).

3.3   Applications received from Custodians must be accompanied by a duly completed and signed
      Custodian Certificate.

3.4   In providing the Custodian Certificate, the Custodian may rely on information provided to it by the
      Participating Beneficiary and any Downstream Custodian.

3.5   For the purposes of the ASIC Instrument, you are a "custodian" if you provide a custodial or depositary
      service in relation to shares of a body or interests in a registered scheme who:

      (a)    holds an Australian financial services licence covering the provision of custodial or depositary
             service;

      (b)    is exempt from the requirement to hold an Australian financial services licence covering the
             provision of a custodial or depository service;

      (c)    holds an Australian financial services licence covering the operation of an IDPS or is a responsible
             entity of an IDPS-like scheme;

      (d)    is a trustee of a self-managed superannuation fund or a superannuation master trust; or

      (e)    is a registered holder of shares or interests in the class and is noted on the register of members of
             the body or scheme as holding the shares or interests on account of another person.

3.6   If you hold Shares as a trustee or nominee for another person, but are not a Custodian, you cannot
      participate for beneficiaries in the manner described above.

3.7   Nominees and custodians may not distribute this Booklet, and may not permit any beneficial shareholder
      to participate in the Offer, in any country outside Australia, South Africa, New Zealand, the European
      Union (Germany and Netherlands), Jersey (Channel Islands), Mauritius, Singapore or the United Kingdom
      except, with the consent of the Company, to beneficial shareholders resident in certain other countries
      where the Company may determine it is lawful and practical to make the Offer.

3.8    The Company is not required to determine, and will not determine, the identity or residence of any
       beneficial owners of Shares. Each Custodian will need to determine for itself whether its beneficiaries are
       Custodian Beneficiaries.

4.    Raising Amount and Scale-back

4.1    The Share Purchase Plan is intended to raise up to the SPP Amount of A$4.0 million (~ZAR46 million). The
       Company, however, reserves absolute discretion to determine the final amount raised under the Share
       Purchase Plan.

4.2    The Company may in its discretion accept oversubscriptions above this amount, subject to compliance
       with the ASX Listing Rules (including that the number of New Shares issued under the Share Purchase
       Plan does not exceed 30% of the number of Shares currently on issue) and the ASIC Instrument.

4.3    If subscriptions received by Orion under the Share Purchase Plan exceed the SPP Amount, or such other
       amount determined by the Board, Orion may also elect to scale back the maximum number of New
       Shares issued to each Eligible Shareholder to the extent and in the manner that it sees fits in its absolute
       discretion. Without limiting the Board's discretion, the Board may have regard to the applicant's
       shareholding when determining and applying any Scale-back. Further, without limiting the Company's
       discretion to scale back applications, if you apply for a ZAR amount of New Shares and the exchange
       rate varies such that the dollar amount you applied for exceeds A$30,000 (being the maximum limit
       under the ASIC Instrument), New Shares having a total issue price equal to A$30,000 will be issued to you
       and you will be refunded the excess cash amount (without interest).

4.4    If a Scale-back occurs, you may receive less than the parcel of New Shares for which you have applied.
       If a Scale-back produces a fractional number of Shares when applied to your issue of New Shares, the
       number of New Shares you will be allocated will be rounded down to the nearest whole number of New
       Shares.

4.5    If there is a Scale-back, your application monies may be greater than the value of the New Shares you
       will be issued. In such event, the excess application monies will be refunded to you without interest, by
       direct credit (to your nominated account as recorded on Orion's Share register) or cheque (to your
       address as shown on Orion's share register) or such other manner as Orion may determine in consultation
       with you, as soon as practicable.

5.    Number of New Shares to be issued and Rounding

5.1    If you apply for New Shares under the Share Purchase Plan, you agree that you are applying for a certain
       value at the SPP Price, rather than a certain number of New Shares.

5.2    If your application is accepted, Orion will divide the value of your application monies by the SPP Price
       (as outlined in section 1 of the "Frequently Asked Questions" section above) in order to determine the
       number of New Shares which, subject to Scale-back, will be issued to you.

5.3    Fractional Shares will not be issued and any fraction of a share will be rounded down to the nearest
       whole number of Shares.

5.4    If the amount of money tendered with your application is less than the minimum application amount of
       A$170 (approximately ZAR2,000), the Company reserves the right to reject your application and refund
       your payment (without interest) and not issue any New Shares to you, with any refund being by direct
       credit (to your nominated account as recorded on Orion's Share register) or cheque (to your address as
       shown on Orion's Share register) or such other manner as Orion may determine in consultation with you,
       as soon as practicable.

6.    ASIC Instrument compliance

       A registered holder of Shares will be ineligible to participate in the Share Purchase Plan if their
       participation would be in breach of the ASIC Instrument.

7.     Dispute resolution, waiver, withdrawal, suspension, and termination

       Orion may settle in any manner it deems appropriate any difficulties, anomalies, or disputes which may
       arise in connection with the operation of the Share Purchase Plan and its decision shall be conclusive
       and binding on all participants and other persons to whom the determination relates. Orion reserves the
       right to waive strict compliance with any provisions of this Booklet, to amend or vary the terms and
       conditions set out in this Booklet and to suspend or terminate the Share Purchase Plan at any time. Any
       such amendment, variation, suspension or termination will be binding on all Eligible Shareholders even
       where Orion does not notify you of that event. In the event that the Share Purchase Plan is terminated
       prior to the issue of New Shares, all application monies will be refunded to you, without interest, by direct
       credit (to your nominated account as recorded on Orion's Share register) or cheque (to your address as
       shown on Orion's Share register) or such other manner as Orion may determine in consultation with you
       as soon as practicable.

10.   Governing Law

       This Booklet and offer under the Share Purchase Plan is governed by the laws in force in Victoria,
       Australia.


Before you apply for New Shares under the Share Purchase Plan, you should seek professional financial and/or
taxation advice to assist you in determining whether or not, and the extent to which, you wish to participate in
the Share Purchase Plan (taking into account your own financial situation, needs and objectives). Orion and its
officers make no recommendation about whether or not you should apply for New Shares under the Share
Purchase Plan, and nothing in this Booklet (including the Application Form) or any other accompanying
documentation constitutes investment or financial product advice or is intended to influence your decision
whether or not to participate in the Share Purchase Plan.
                                                                                                       All Registry communications to:
