4. Resolution 1 – Remuneration Report

4.1 General

In accordance with section 250R(2) of the Corporations Act, the Company must put the Remuneration Report to the vote of Shareholders. The Directors' Report for the year ended 31 December 2025 in the 2025 Annual Report contains the Remuneration Report which sets out the remuneration policy for the Company and the remuneration arrangements in place for the executive Directors, specified executives and non-executive Directors.

In accordance with section 250R(3) of the Corporations Act, Resolution 1 is advisory only and does not bind the Directors. If Resolution 1 is not passed, the Directors will not be required to alter any of the arrangements in the Remuneration Report.

If the Remuneration Report receives a 'no' vote of 25% or more (Strike) at two consecutive annual general meetings, Shareholders will have the opportunity to remove the whole Board, except the managing director (if any).

Where a resolution on the Remuneration Report receives a Strike at two consecutive annual general meetings, the Company will be required to put to Shareholders at the second annual general meeting a resolution on whether another meeting should be held (within 90 days) at which all Directors (other than the Managing Director, if any) who were in office at the date of approval of the applicable Directors' Report must stand for re-election.

The Company's Remuneration Report did not receive a Strike at the 2025 annual general meeting held on 29 May 2025. If the Remuneration Report receives a Strike at this Meeting, Shareholders should be aware that if a second Strike is received at the 2027 annual general meeting, this may result in the re-election of the Board.

The Chair will allow a reasonable opportunity for Shareholders as a whole to ask about, or make comments on the Remuneration Report.

4.2 Additional information

Resolution 1 is an ordinary resolution.

Given the personal interests of all Directors in the outcome of this Resolution, the Board declines to make a recommendation to Shareholders regarding this Resolution.

5. Resolution 2 – Election of Director – Nathan Marr

5.1 General

Article 7.2(b) of the Constitution and Listing Rule 14.5 both provide that there must be an election of directors at each annual general meeting of the Company. In accordance with Article 7.2(b)(iv) of the Constitution, if no person or Director is standing for election or re-election in accordance with Articles 7.2(b)(i) to (iii) of the Constitution, then this requirement can be satisfied by any Director who wishes to retire and stand for re-election.

Page 8


Article 7.3 of the Constitution provides that a retiring Director holds office until the conclusion of that meeting at which that Director retires but is eligible for re-election. All the Directors (excluding the Managing Director) were last elected at the Company's 2025 annual general meeting held on 29 May 2025. Nathan Marr has agreed to retire as a Director at this Meeting and, being eligible and offering himself for election, seeks re-election pursuant to Resolution 2.

If Resolution 2 is passed, Mr Marr will be elected as a Director of the Company with effect from the conclusion of the Meeting.

If Resolution 2 is not passed, Mr Marr will not be elected as a Director of the Company.

5.2 Nathan Marr

Nathan Marr is a mining executive who holds a Bachelor of Science – Metallurgy and Chemistry. He has over 32 years' mining experience across process engineering, design, construction, commissioning, project management, operations and corporate asset management for gold/silver, gold, gold/copper, nickel, copper, iron ore (magnetite and hematite), tungsten projects across the globe.

Mr Marr was the senior process engineer for the development of Manantial Espejo silver project in Argentina, producing 4.1Moz of silver and 60,000oz of gold per year, and the Hidden Valley Silver Gold project in Papua New Guinea, producing the equivalent of 3.5Moz of silver and 250,000oz of gold per year.

Mr Marr does not currently hold any other material directorships, other than as disclosed in this Notice.

Mr Marr is considered by the Board (with Mr Marr abstaining) to be an independent Director. Mr Marr is not considered by the Board to hold any interest, position or relationship that might influence, or reasonably be perceived to influence, in a material respect his capacity to bring an independent judgment to bear on issues before the Board and to act in the best interests of the entity as a whole rather than in the interests of an individual security holder or other party.

Mr Marr has acknowledged to the Company that he will have sufficient time to fulfil his responsibilities as a Director.

5.3 Board recommendation

The Board (other than Mr Marr who has a personal interest in the outcome of this Resolution) supports the election of Mr Marr for the following reasons:

(a) Mr Marr's technical skills and significant experience across process engineering, design, construction commissioning, project management, operations and corporate asset management for gold/silver, gold, gold/copper, nickel, copper, iron ore (magnetite and hematite), tungsten projects is an important component to the Board's skills and experience; and

(b) Mr Marr's contribution to the Board's activities to date have been invaluable and Mr Marr will continue to enhance the Board's ability to perform its role.

5.4 Additional information

Resolution 2 is an ordinary resolution.

Page 9


Page 10

6. Resolution 3 – Approval of 7.1A Mandate (additional 10% placement capacity)

6.1 General

Broadly speaking, and subject to a number of exceptions, Listing Rule 7.1 limits the amount of equity securities that a listed company can issue without the approval of its shareholders over any 12 month period to 15% of the fully paid ordinary securities it had on issue at the start of that period.

Listing Rule 7.1A enables an eligible entity to issue Equity Securities up to 10% of its issued share capital through placements over a 12-month period after the annual general meeting (10% Placement Facility). The 10% Placement Facility is in addition to the Company's 15% annual placement capacity under Listing Rule 7.1.

Resolution 3 seeks Shareholder approval to provide the Company with the ability to issue Equity Securities under the 10% Placement Facility during the 10% Placement Period (refer to Section 6.2(f) below). The number of Equity Securities to be issued under the 10% Placement Facility will be determined in accordance with the formula prescribed in Listing Rule 7.1A.2 (refer to Section 6.2(c) below).

If Resolution 3 is passed, the Company will be able to issue Equity Securities up to the combined 25% limit in Listing Rules 7.1 and 7.1A without any further Shareholder approval.

If Resolution 3 is not passed, the Company will not be able to access the additional 10% capacity to issue Equity Securities without Shareholder approval provided for in Listing Rule 7.1A and will remain subject to the 15% limit on issuing Equity Securities without Shareholder approval in Listing Rule 7.1.

6.2 Listing Rule 7.1A

(a) Is the Company an eligible entity?

An eligible entity for the purposes of Listing Rule 7.1A is an entity that is not included in the S&P/ASX 300 Index and has a market capitalisation of $300 million or less.

The Company is an eligible entity as it is not included in the S&P/ASX 300 Index and has an undiluted market capitalisation of approximately $276.0 million, based on the closing price of Shares $1.500 on 16 April 2026.

(b) What Equity Securities can be issued?

Any Equity Securities issued under the 10% Placement Facility must be in the same class as an existing quoted class of Equity Securities of the eligible entity.

As at the date of this Notice, the Company has one quoted class of Equity Securities, being Shares.


(c) How many Equity Securities can be issued?

Listing Rule 7.1A.2 provides that under the approved 10% Placement Facility, the Company may issue or agree to issue a number of Equity Securities calculated in accordance with the following formula:

$$
(A \times D) - E
$$

Where:

A = is the number of Shares on issue at the commencement of the Relevant Period:

(A) plus the number of fully paid Shares issued in the Relevant Period under an exception in Listing Rule 7.2 other than exceptions 9, 16 or 17;

(B) plus the number of fully paid Shares issued in the Relevant Period on the conversion of convertible securities within Listing Rule 7.2 exception 9 where:

(1) the convertible securities were issued or agreed to be issued before the commencement of the Relevant Period; or

(2) the issue of, or agreement to issue, the convertible securities was approved, or taken under the Listing Rules to have been approved, under Listing Rule 7.1 or Listing Rule 7.4;

(C) plus the number of fully paid Shares issued in the Relevant Period under an agreement to issue securities within Listing Rule 7.2 exception 16 where:

(1) the agreement was entered into before the commencement of the Relevant Period; or

(2) the agreement or issue was approved, or taken under the Listing Rules to have been approved, under Listing Rule 7.1 or Listing Rule 7.4;

(D) plus the number of partly paid Shares that became fully paid Shares in the Relevant Period;

(E) plus the number of fully paid Shares issued in the Relevant Period with approval under Listing Rules 7.1 and 7.4; and

(F) less the number of fully paid Shares cancelled in the Relevant Period.

Note that 'A' has the same meaning in Listing Rule 7.1 when calculating the Company's 15% annual placement capacity.

D = is 10%.

E = is the number of Equity Securities issued or agreed to be issued under Listing Rule 7.1A.2 in the 12 months before the date of the issue or agreement to issue, where the issue or agreement has not been subsequently approved by Shareholders under Listing Rule 7.4.

Page 11


(d) What is the interaction with Listing Rule 7.1?

The Company's ability to issue Equity Securities under Listing Rule 7.1A will be in addition to its 15% annual placement capacity under Listing Rule 7.1.

(e) At what price can the Equity Securities be issued?

Any Equity Securities issued under Listing Rule 7.1A must be issued for a cash consideration per Equity Security which is not less than 75% of the VWAP of Equity Securities in the same class calculated over the 15 Trading Days on which trades in that class were recorded immediately before:

(i) the date on which the price at which the Equity Securities are to be issued is agreed by the Company and the recipient of the Equity Securities; or
(ii) if the Equity Securities are not issued within 10 Trading Days of the date in paragraph (i) above, the date on which the Equity Securities are issued, (Minimum Issue Price).

(f) When can Equity Securities be issued?

Shareholder approval of the 10% Placement Facility under Listing Rule 7.1A will be valid from the date of the Meeting and will expire on the earlier of:

(i) the date that is 12 months after the date of the Meeting;
(ii) the time and date of the Company's next annual general meeting; or
(iii) the time and date of Shareholder approval of a transaction under Listing Rules 11.1.2 (a significant change to the nature or scale of activities) or 11.2 (disposal of main undertaking),

(10% Placement Period).

(g) What is the effect of Resolution 3?

The effect of Resolution 3 will be to allow the Company to issue the Equity Securities under Listing Rule 7.1A during the 10% Placement Period without further Shareholder approval or using the Company's 15% annual placement capacity under Listing Rule 7.1.

6.3 Specific information required by Listing Rule 7.3A

Pursuant to and in accordance with Listing Rule 7.3A, the following information is provided in relation to the 10% Placement Facility:

(a) Final date for issue

The Company will only issue the Equity Securities under the 10% Placement Facility during the 10% Placement Period (refer to Section 6.2(f) above).

Page 12


(b) Minimum issue price

Where the Company issues Equity Securities under the 10% Placement Facility, it will only do so for cash consideration and the issue price will be not less than the Minimum Issue Price (refer to Section 6.2(e) above).

(c) Purposes of issues under the 10% Placement Facility

The Company may seek to issue Equity Securities under the 10% Placement Facility for the purposes of raising funds for continued investment in the Company's current assets, the acquisition of new assets or investments (including expenses associated with such an acquisition), and/or for general working capital.

(d) Risk of economic and voting dilution

Shareholders should note that there is a risk that:

(i) the market price for the Company's Equity Securities may be significantly lower on the date of the issue of the Equity Securities than on the date of the Meeting; and

(ii) the Equity Securities may be issued at a price that is at a discount to the market price for the Company's Equity Securities on the issue date,

which may have an effect on the amount of funds raised by the issue of the Equity Securities.

If this Resolution 3 is approved by Shareholders and the Company issues Equity Securities under the 10% Placement Facility, the existing Shareholders' economic and voting power in the Company may be diluted as shown in the below table (in the case of convertible Securities, only if the convertible Securities are converted into Shares).

The table below shows the dilution of existing Shareholders based on the current market price of Shares and the current number of Shares for Variable 'A' calculated in accordance with the formula in Listing Rule 7.1A.2 (refer to Section 6.2(c) above) as at the date of this Notice (Variable A), with:

(i) two examples where Variable A has increased by 50% and 100%; and

(ii) two examples of where the issue price of Shares has decreased by 50% and increased by 100% as against the current market price.

100% increase in Variable A Funds raised $27,601,788 $55,203,576 $110,407,152

Notes:

  1. The table has been prepared on the following assumptions:

(a) The issue price is the current market price ($1.500), being the closing price of the Shares on ASX on 16 April 2026, being the latest practicable date before this Notice was signed.

(b) Variable A comprises of 184,011,922 existing Shares on issue as at the date of this Meeting, assuming the Company has not issued any Shares in the 12 months prior to the Meeting that were not issued under an exception in Listing Rule 7.2 or with Shareholder approval under Listing Rule 7.1 and 7.4.

(c) The Company issues the maximum number of Equity Securities available under the 10% Placement Facility.

(d) No convertible Securities (including any issued under the 10% Placement Facility) are exercised or converted into Shares before the date of the issue of the Equity Securities.

(e) The issue of Equity Securities under the 10% Placement Facility consists only of Shares. If the issue of Equity Securities includes quoted Options, it is assumed that those quoted Options are exercised into Shares for the purpose of calculating the voting dilution effect on existing Shareholders.

  1. The number of Shares on issue (i.e. Variable A) may increase as a result of issues of Shares that do not require Shareholder approval (for example, a pro rata entitlements issue, scrip issued under a takeover offer or upon exercise of convertible securities) or future specific placements under Listing Rule 7.1 that are approved at a future Shareholders' meeting.

  2. The 10% voting dilution reflects the aggregate percentage dilution against the issued Share capital at the time of issue. This is why the voting dilution is shown in each example as 10%. The table does not show an example of dilution that may be caused to a particular Shareholder by reason of placements under the 10% Placement Facility, based on that Shareholder's holding at the date of the Meeting.

  3. The table shows only the effect of issues of Equity Securities under Listing Rule 7.1A, not under the 15% placement capacity under Listing Rule 7.1.

(e) Allocation policy

The Company's allocation policy is dependent on the prevailing market conditions at the time of any proposed issue pursuant to the 10% Placement Facility. The identity of the allottees of Equity Securities will be determined on a case-by-case basis having regard to the factors including but not limited to the following:

(i) the methods of raising funds that are available to the Company, including but not limited to, rights issues or other issues in which existing Shareholders can participate;

(ii) the effect of the issue of the Equity Securities on the control of the Company;

(iii) financial situation and solvency of the Company; and

(iv) advice from corporate, financial and broking advisers (if applicable).
