In this Explanatory Memorandum, unless otherwise indicated all dollar amounts are expressed in Australian dollars. Unless otherwise stated, the information contained in this Explanatory Memorandum is as of the date of the Notice.

The directors recommend that Shareholders read this Explanatory Memorandum in full before making any decision regarding the matters set forth in the Notice.

Representatives of the Company’s auditors, PwC, will be present to take questions and comments from Shareholders about the conduct of the audit and the preparation and content of the audit report.

Companies are no longer required to mail out a hard copy of their annual report to shareholders except to those shareholders who have elected to receive a hard copy and notified the Company to that effect. Shareholders who have not already made such an election may obtain a hard copy of the Annual Report by contacting the Company. Alternatively, the Annual Report is available on the Company’s website at www.perseusmining.com and may be downloaded or read online.

2. Resolution 1 - Adoption of Remuneration Report

Pursuant to section 250R(2) of the Corporations Act, the Company submits to Shareholders for consideration and adoption, by way of a non-binding resolution, its remuneration report for the year ended 30 June 2025 (the “ Remuneration Report ”). The Remuneration Report is a distinct section of the Annual Report which deals with the remuneration of directors and executives of the Company.

By way of summary, the Remuneration Report:

• (b) addresses the relationship between the Company’s remuneration policy and the Company’s performance; and

• (c) sets out the remuneration details for each director and executive officer named in the Remuneration Report for the financial year ended 30 June 2025.

ABN 27 106 808 986

==> picture [85 x 27] intentionally omitted <==

The directors recommend that Shareholders vote in favour of the adoption of the Remuneration Report. As previously stated, this resolution is advisory only and does not bind the directors or the Company. However, the Board will take the outcome of the vote on this resolution into consideration when reviewing the remuneration practices and policies of the Company in the future. The Chair will provide Shareholders with reasonable opportunity at the Meeting to ask questions about, or to make comments on, the Remuneration Report.

If at least 25% of the votes cast at the Meeting on Resolution 1 are voted against adoption of the Remuneration Report, and then again at the Company’s next annual general meeting, the Company will be required to put to Shareholders a resolution at that meeting proposing the calling of a general meeting to consider the appointment of new directors of the Company (“ Spill Resolution ”). If more than 50% of Shareholders vote in favour of the Spill Resolution, the Company must convene a general meeting (“ Spill Meeting ”) within 90 days of the Company’s next annual general meeting. All of the directors who are in office when the Company’s 2025 Directors’ Report is approved, other than the managing director of the Company, would cease to hold office immediately before the end of the Spill Meeting but may stand for re-election at the Spill Meeting.

Chairman authorised to exercise undirected proxies : Where Shareholders have appointed the Chair as their proxy, the Chair will vote in favour of Resolution 1 “Adoption of Remuneration Report” unless the Shareholder has expressly indicated a different voting intention. This is so notwithstanding that the resolution is connected directly or indirectly with the remuneration of a member of key management personnel, which includes the Chair.

3. Resolutions 2 and 3 - Re-Election of Mr Rick Menell and Mr John McGloin as Directors

In accordance with the requirements of the Company’s Constitution and Listing Rules 14.4 and 14.5, one-third of the directors of the Company (excluding the managing director), and those who were last re-elected more than three years ago, must retire from office at the Meeting but if they are eligible, may offer themselves for re-election. In accordance with these requirements, Mr Menell and Mr McGloin retire at the Meeting. Being eligible, both Mr Menell and Mr McGloin have offered themselves for re-election.

Details of Mr Menell’s and Mr McGloin’s qualifications and experience are available in the Annual Report. Mr Menell has been a director of the Company since 2024. Mr McGloin has been a director of the Company since 2016. In accordance with Company’s Board Charter, if re-elected, this would be Mr McGloin’s final term given the maximum 10-year term requirement in the Charter. The Board considers both Mr Menell and Mr McGloin to be independent.

Exemption from TSX Rules

In reliance on Section 401.1 of the TSX Company Manual, the Company has sought and been granted an exemption from the requirements of Section 461.1 to 461.4 of the TSX Company Manual, the effect of which is that (i) not every director of the Company must submit himself for re-election at the Meeting; and (ii) the Company is not required to have a majority voting policy in respect of director elections. Effectively, the re-election of directors for the purposes of this Meeting is subject only to the requirements of the Company’s Constitution, the ASX Listing Rules and the Corporations Act. The Company sought the exemption on the basis that: (i) the Company’s primary listing is the Australian Stock Exchange; (ii) the Company is incorporated in Australia; and (iii) less than 25% of trading volume in the Company’s shares was on Canadian marketplaces. In accordance with the requirement to notify the TSX of its continued reliance on the exemption before each successive annual general meeting, the Company has notified the TSX of such continued reliance.

In view of their respective expertise, experience and contributions already made, the directors (excluding Mr Menell and Mr McGloin in respect of their own re-election) recommend that Shareholders vote in favour of the re-election of Mr Menell and Mr McGloin.

==> picture [85 x 27] intentionally omitted <==

If Shareholders approve Resolutions 2 and/or 3, Mr Menell in the case of Resolution 2, and Mr McGloin, in the case of Resolution 3, will be re-elected as directors of the Company. If Shareholders do not approve Resolutions 2 and/or 3, Mr Menell, in the case of Resolution 2, and Mr McGloin, in the case of Resolution 3, will cease to be directors of the Company.

4. Resolution 4 – Re-election of Mr Jim Rutherford as a Director

In accordance with the requirements of clause 7.1 of the Company’s Constitution and ASX Listing Rule 14.4, directors who have been appointed by the Board since the previous annual general meeting, must retire from office at the Meeting but if they are eligible, may offer themselves for reelection. In accordance with these requirements, Mr Rutherford retires at the Meeting. Being eligible, Mr Rutherford has offered himself for re-election.

Details of Mr Rutherford’s qualifications and experience are available in the Annual Report. Mr Rutherford is a highly experienced investment professional with over 25 years spent working the global mining and metals sector, including senior roles at Capital Group, HSBC James Capel and Credit Lyonnais Securities. He currently serves as a Director of Manara Minerals Investment Co and is a NonExecutive Director of Ecora Resources and Minera Cobre de Colombia. He was previously NonExecutive Chairman of Centamin plc and held Board roles with Anglo American, GT Gold and Dalradian Resources. The Board considers Mr Rutherford to be independent.

In view of Mr Rutherford extensive expertise and experience, the Directors (excluding Mr Rutherford) recommend that Shareholders vote in favour of Mr Rutherford’s re-election.

5. Resolution 5 - Approval of Issue of Performance Rights to Mr Jones

Shareholder approval is being sought for the granting of Performance Rights (“ PRs ”) to Mr Craig Jones, the Managing Director and Chief Executive Officer of the Company.

The Directors (excluding Mr Jones), based on recommendations by the Board’s Remuneration Committee, are seeking approval for the issue of 436,334 PRs to Mr Jones, which, subject to satisfaction of vesting criteria, can convert to up to 436,334 fully paid ordinary shares.

The Shares issuable upon exercise of the PRs to be granted to Mr Jones represent 0.0003% of the issued and outstanding Shares of the Company on the date hereof. The PRs proposed for issue will be subject generally to the terms and conditions of the PR Plan which was approved by Shareholders at the annual general meeting held on 21 November 2023 the material terms of which are summarised in Attachment 1 . A copy of the plan may be obtained by contacting the Company. PRs are contractual rights only and do not entitle the holder to any entitlements Shareholders have, such as voting rights, dividends, return or reduction of capital, participation in surplus profits or assets upon a winding up, participation in new issues unless and until the PRs have vested and have been converted into Shares. The quantum of the PRs is determined by reference to the executive’s total fixed remuneration (“ TFR ”), being $1,060,000 per annum as at 18 August 2025. The “at risk” component of Mr Jones’s remuneration package is allocated into short term incentive (“ STI ”) (target of 75% of TFR) subject to specified vesting criteria to be satisfied in a financial year and payable in cash and long-term incentive (“ LTI ”) (up to 150% of TFR).

LTI. The LTI is payable through an issue of securities in the Company by way of participation in the PR Plan. The number of LTI PRs to be issued was calculated by taking the cash amount - 150% of Mr Jones’s TFR for the LTI PRs - and divide that number by the volume weighted average price (“ VWAP ”) of Perseus’s shares on the ASX during the 20 trading days before 1 July 2025, which was $ 3.644. Mr Jones TFR at 18 August 2025 was $1,060,000 which multiplied by 1.5 and then divided by the VWAP of $3.644 results in 436,334 PRs for his LTI. The issue of PRs and their subsequent conversion, if any, to shares in the Company enables the alignment of Mr Jones’s interests with those of the Shareholders. The vesting conditions for the LTI PRs are measured over a three year period (1 July

9

ABN 27 106 808 986

==> picture [85 x 27] intentionally omitted <==

2025 to 30 June 2028) and constitute: (1) a comparison of the three year average total shareholder return (“ TSR ”) of a group of gold explorers, developers and producers which were considered by Perseus to be its peers (based on market capitalization, precious metals and/or West African production focused) (“ Peer Group ”); (2) a measure of Return on Invested Capital (“ ROIC ”) to assess shareholder value creation against Perseus’s weighted average cost of capital; and (3) a growth component based on Group reserves growth over a period of three years. The three vesting criteria are weighted equally at 33.33% each.

In August 2025, the Company issued PRs to a number of its employees and executives (“ 2025 PRs ”). The vesting conditions will be measured over a three year period (1 July 2025 to 30 June 2028). The vesting conditions for the PRs for Mr Jones, for which approval is sought at the Meeting, are the same as those for the 2025 PRs for the TSR and Reserves Growth criteria. A ten percent (10%) internal benchmark has been set as the minimum vesting threshold for ROIC.

Subject to the Board’s discretion described below and provided individual performance is rated as at least satisfactory, the 2025 PRs would vest or be forfeited as follows:

For 33.33% of PRs:

Relative TSR over the Vesting Period	Proportion of Performance Rights vested
(33.33% Weighting)
Below the 50th percentile	0%
At the 50th percentile	50%
Between the 50th and the 75th percentile	Pro-rata between 50% and 100%
Above the 75th percentile	100%

For 33.33% of PRs:

Return on Invested Capital (ROIC)	Proportion of Performance Rights vested
(33.33% Weighting)
ROIC below 10%	0%
ROIC at 10%	50%
ROIC between 10% and 12.5%	Between 50% and 75% vesting, calculated on a linear basis
ROIC between 12.5% and 15%	Between 75% and 100% vesting, calculated on a linear basis
ROIC at or above 15%	100%

10

ABN 27 106 808 986

==> picture [85 x 27] intentionally omitted <==

For 16.67% of PRs:

Reserves Growth Performance	Performance Vesting Outcomes
Reserves depleted	0% vesting
Reserves maintained	50% vesting
Reserves grown by up to 15%	Between 50% and 100% vesting, calculated on a linear basis.
Reserves grown by 15% or more	100% vesting

For 16.67% of LTI PRs: delivery of the Nyanzaga Gold Project in line with the Board approved final investment decision.

However, the Board has the ultimate discretion to vest PRs even if performance conditions have not been met or to not vest PRs even if performance conditions have been met. The Board has exercised this discretion in the past. The Board believes that the grant of PRs with these vesting conditions to Mr Jones will provide him, as the Company’s Chief Executive Officer, with incentive to achieve the long-term performance objectives of the Company by aligning shareholder return objectives with the vesting of his PRs.

The PRs proposed for grant to the executive are subject to the terms and conditions of the PR Plan and are ‘at risk’ in view of the vesting conditions described above.

At the date of this Notice, there are no performance rights issued and outstanding to Mr Jones.

Shareholder approval is required under ASX Listing Rule 10.14 for the issue of PRs to Mr Jones as he is a Director and therefore a related party of the Company under Listing Rule 10.11.1. ASX Listing Rule 10.14 provides that the Company must not issue equity securities under an employee incentive scheme to a director of the Company without Shareholder approval. As the PR Plan is an employee incentive scheme as referred to in ASX Listing Rule 10.14 and Mr Jones is a director of the Company, Shareholder approval is sought for the issue of PRs to Mr Jones. If such approval is not received, no PRs will be granted to Mr Jones. In such event cash arrangements may be put in place to provide Mr Jones with similar incentives as the Company’s other executives who have been granted PRs under the PR Plan. The Board has considered the application of Chapter 2E of the Corporations Act and has resolved that the reasonable remuneration exception provided by Section 211 of the Corporations Act is relevant in the circumstances and accordingly, the Company will not also seek approval for the issue of PRs to Mr Jones pursuant to Section 208 of the Corporations Act. ASX Listing Rule 10.15 requires the following information to be provided in relation to the PRs proposed to be granted to Mr Jones pursuant to the PR Plan:

• ( a ) The number of PRs (and hence the maximum number of Shares) to be issued to Mr Jones is 436,334.

• (b) No consideration is payable by Mr Jones at the time of issue of the PRs or upon vesting thereof into ordinary shares.

• (c) At the date of this Notice, no PRs have been issued to Mr Jones. No PRs have been issued to non-executive directors.

• (d) Participation in the PR Plan is available to Eligible Participants, as defined in the PR Plan. Mr Jones has been determined to be an Eligible Participant for the purposes of the PR Plan. Non-executive directors are not eligible to participate.

• (e) No loans will be made by the Company in connection with the issue of PRs to Mr Jones or their vesting, if any, into shares.

11

ABN 27 106 808 986

==> picture [85 x 27] intentionally omitted <==

• (f) If the Resolution is approved, it is intended that the PRs will be issued to Mr Jones as soon as possible after the date of the Meeting and in any event no later than one year after the date of the Meeting (or such later date as permitted by ASX by way of a waiver from the Listing Rules). The PRs will have a vesting and measurement period from 1 July 2025 until 30 June 2028. Subject to satisfaction of vesting criteria (detailed elsewhere in this Explanatory Memorandum), conversion of PRs to Shares may occur after the end of the term.

• (g) Refer to page 10&11 of this Notice for details of Mr Jones total remuneration package as well as the value attributed to the PRs by reference to a percentage of Mr Jones’s TFR and the share price.

• (h) All other terms and conditions of PRs proposed for grant to Mr Jones are as described in the PR Plan, summarised in Attachment 1 and on page 10, 11 & 12 of this Notice.

• (i) A voting exclusion statement in respect of Resolution 5 is included in the Notice of Meeting.

• (j) Details of any securities issued under the PR Plan will be published in the Company’s annual report relating to a period in which they were issued, along with a statement that approval for the issue was obtained under ASX Listing Rule 10.14. Any additional persons covered by ASX Listing Rule 10.14 who become entitled to participate in the PR Plan after the Resolution is approved and who were not named in the Notice of Meeting will not participate until approval is obtained under that rule.

The Board, excluding Mr Jones because of his interest in this matter, recommends that Shareholders vote in favour of the issue of PRs to Mr Jones. If Shareholders approve the Resolution, the Performance Rights will be issued to Mr Jones as per the Resolution. If Shareholders do not approve the Resolution, the proposed Performance Rights will not be issued.

INFORMATION FOR CANADIAN HOLDERS

Designated Foreign Issuer Status

The Company confirms that it is a designated foreign issuer as defined in National Instrument 71-102 – Continuous Disclosure and Other Exemptions Relating to Foreign Issuers and is subject to Australian law and the regulatory requirements of the ASX. As a result, the Company does not include a management information circular pursuant to National Instrument 51-102 - Continuous Disclosure Obligations (“NI 51-102”) in this Notice of Meeting.

Advice for Beneficial Holders

Shares may not be registered in the Shareholder’s name but in the name of an intermediary (which is usually a bank, trust company, securities dealer or broker, or a clearing agency in which an intermediary participates). A non-registered Shareholder cannot be recognized at the Meeting for the purpose of voting his Shares unless such holder is appointed by the applicable intermediary as a proxyholder.

The Company is distributing Meeting materials to non-objecting beneficial owners in accordance with National Instrument 54-101 – Communications with Beneficial Shareholders (“ NI 54-101 ”). Persons who are objecting beneficial owners for the purposes of NI 54-101 will not receive Meeting materials unless the beneficial owner’s intermediary assumes the cost of delivery. Non-registered Shareholders who receive meeting materials will be given a voting instruction form (a “ VIF ”) which must be completed and signed by the non-registered Shareholder in accordance with the instructions noted on it. In this case, the mechanisms described above for registered Shareholders cannot be used and the instructions on the VIF must be followed (which in some cases may allow completion of the VIF by telephone or the Internet). The VIF is provided instead of a proxy. By returning the VIF in accordance with its instructions, a non-registered owner is able to instruct the registered Shareholder how to vote on behalf of the non-registered owner. The purpose of these procedures is to allow non-registered Shareholders to direct the voting of the shares that they own but that are not registered in their name. Should a non-registered Shareholder wish to attend and vote at the Meeting in person (or have another person attend and vote on his behalf), the non-registered Shareholder should carefully follow the instructions provided on the VIF.

Proxies returned by intermediaries as “non-votes” because the intermediary has not received instructions from the non-registered Shareholder with respect to the voting of certain shares or, under applicable stock exchange or other rules, the intermediary does not have the discretion to vote those Shares on one or more of the matters that come before the Meeting, will be treated as not entitled to vote on any such matter and will not be counted as having those Shares voted in respect of any such matter.

ATTACHMENT 1

KEY TERMS OF THE PERSEUS MINING LIMITED PERFORMANCE RIGHTS PLAN

The current version of the PR Plan was approved by shareholders at the AGM in November 2023 and applies to all Performance Rights currently on issue.

• (i) Participation: The Performance Rights Plan is available to Eligible Participants, as defined below, of the Company and its related bodies corporate, as such term is defined in the Corporations Act (collectively, the “ Group ” and each a “ Group Member ”). Eligible Participants are full and part-time employees and directors of a Group Member, and Eligible Contractors (collectively, “ Eligible Participants ”). An Eligible Contractor means an individual, or company, that has performed work for a Group Member for more than 12 months and received 80% or more of its income from a Group Member. No payment is required for a grant of Performance Rights, nor for the conversion of the Performance Rights to ordinary shares.

• (ii) Maximum Number Issuable: An invitation to apply for Performance Rights will not be made where the grant of Performance Rights contemplated by the invitation would result in the Company exceeding the limit that applies under any applicable law from time to time. The limit that currently applies is 5% of the issued capital of the Company. The Performance Rights Plan also provides that the maximum number of Shares that may be issuable pursuant to Performance Rights under the Performance Rights Plan, together with all of the Company’s other previously established or proposed security based compensation arrangements, shall not exceed 10% of the Company’s total issued shares from time to time. The Performance Rights Plan does not set out a maximum number of Performance Rights that may be granted to insiders of the Company or to any one person or company.

• (iii) Vesting: Vesting conditions may be determined by the Board at the time an invitation is made and may include a minimum employment term. Performance Rights may not be exercised until vesting conditions, as specified in the invitation, have been met. The Board has the discretion not to impose vesting conditions. As described further in item (xi) below, the Board has the power to amend or waive vesting conditions.

• (iv) Lapse: Unless the Board determines otherwise in its absolute discretion, a Performance Right will lapse on the earliest to occur of: (a) a purported transfer, assignment, mortgage, charge, disposition of or encumbrance of the Performance Right, other than with the prior written consent of the Board; (b) the holder of such Performance Right (a “ Performance Rights Holder ”) ceasing to be an Eligible Person for any reason, subject to the provisions described below; (c) a determination by the Board that a Performance Rights Holder has acted fraudulently or dishonestly or is in breach of his or her obligations to any Group Member; (d) subject to any automatic vesting in accordance with the Performance Rights Plan, if applicable vesting conditions have not been met in the prescribed period; (e) the expiry date set out in the related invitation; or (f) the seventh anniversary of the grant of the Performance Right.

• (v) Cessation of Entitlement – Death or Ill Health: Subject to any invitation’s terms and conditions, if a holder of a Performance Right ceases to be an Eligible Person due to ill health or death, then (a) if all relevant vesting conditions are met or no vesting conditions are imposed, Performance Rights may be exercised (by the personal representatives in the case of death) until it lapses in accordance with the terms of the Performance Rights Plan; or (b) if any relevant vesting conditions have not been met, the Performance Rights will automatically lapse immediately upon the Performance Rights Holder ceasing to be an Eligible Participant, unless the Board determines otherwise that all or a portion of those Performance Rights immediately vest, notwithstanding non-fulfilment of the vesting conditions.

• (vi) Cessation of Entitlement – Termination for Cause: Subject to any invitation’s terms and conditions, if the holder of a Performance Right is terminated for cause, then (a) if all relevant vesting conditions are met or no vesting conditions are imposed, the right to exercise Performance Rights is immediately suspended for a period of 10 Business Days, during which period the Board may determine to lift the suspension and allow such Performance Rights to be exercisable for a period of 20 Business Days after the holder ceases to be an Eligible Participant, following which such Performance Rights will lapse (however, if the Board does not determine to lift the suspension, the Performance Rights will automatically lapse at the end of the 10 Business Day suspension); or (b) if any relevant vesting conditions have not been met, the Performance Rights will lapse on the day the holder ceases to be an Eligible Participant.

ABN 27 106 808 986

• (vii) Cessation of Entitlement – Termination by Consent or Cessation of Employment for Other Reasons: Subject to any invitation’s terms and conditions, if a holder of a Performance Right ceases to be an Eligible Participant (a) by their own volition, with the written consent of the Board; (b) by reason of redundancy; or (c) for reasons other than ill health or death, termination for cause or by consent, or redundancy, then: (A) if all relevant vesting conditions are met or no vesting conditions are imposed, the Performance Rights may be exercised for a period of 20 Business Days after the holder ceases to be an Eligible Person, following which such Performance Rights will lapse; or (B) if any relevant vesting conditions have not been met, the Performance Rights will lapse on the day the Performance Rights Holder ceases to be an Eligible Participant, unless the Board determines otherwise that all or a portion of those Performance Rights immediately vest, notwithstanding non-fulfilment of the vesting condition. The PR Plan makes provision for Termination by Consent or redundancy occurring between the end of the vesting and measurement period and the vesting of a Performance Right. The PR Plan provides for the continuation of a Performance Right until the Board determines that the Performance Right may be exercised (in which case the Performance Right automatically vests) or may not be exercised (in which case the Performance Right will automatically lapse).

• (viii) Change of Control: Subject to the terms and conditions of a grant of a Performance Right, unvested Performance Rights automatically vest and are automatically exercised on the occurrence of a change of control.

• (ix) Winding up/Reorganisation: The Board may, in its absolute discretion, permit the exercise of Performance Rights, irrespective of whether the relevant vesting conditions have been met, during such period as the Board determines where the Company passes a resolution for voluntary winding up or an order is made for the Company’s compulsory winding up. In the event of any reorganisation (including consolidation, subdivision, reduction or return) of the issued shares, the number of Performance Rights to which each Performance Rights Holder is entitled will be adjusted in the manner provided for in the listing rules applicable at the time the reorganisation comes into effect.

• (x) Assignability: Performance Rights will be transferable or assignable only with the prior written consent of the Board, which may be withheld in its absolute discretion. If a holder of a Performance Right purports to transfer, assign, mortgage, charge or otherwise dispose of or encumber any Performance Rights without Board consent, the Performance Rights immediately lapse. Performance Rights are transferable to the extent necessary to allow exercise by personal representatives pursuant to the Performance Rights Plan in the event of death of the holder.

• (xi) Amendments: Subject to the rules of the TSX and ASX, the Board may at any time amend or add to all or any of the provisions of the Performance Rights Plan, or the terms or conditions of any Performance Right granted under the Performance Rights Plan, including vesting conditions. Specifically, the Board may amend provisions of the Performance Rights Plan, or the terms or conditions of any Performance Right, for the purposes described as items (a), (b) or (c) below and amend or waive vesting conditions, without shareholder approval. Despite the foregoing, no amendment may be made to the terms of a Performance Right without the consent of the holder of the Performance Right if the effect of the amendment is to reduce the rights of the holder of such Performance Right, other than an amendment introduced primarily (a) for the purpose of complying with present or future legislation or regulations applicable to the Company or the Performance Rights Plan; (b) to correct any manifest error or mistake; or (c) to take into consideration adverse tax implications in respect of the Performance Rights Plan.
