Further Directors John Kelly and Patrick Cook have committed to participate in the SPP,, approvals for which is being sought under Resolution 6 & 7. The SPP Securities are being offered under a Prospectus, the Company is not relying on ASX Listing Rule 7.2 (Exception 5). Shareholders can individually participate up to a maximum of $30,000.

Resolution 1: Ratification of prior issue of 46,929,731 Shares and 46,929,731 Options, as part of Tranche 1 Placement

Background

As noted above, the Company is seeking shareholder approval pursuant to ASX Listing Rule 7.4 to ratify the issue of 46,929,731 Shares in the Company. at an issue price of $0.0185 (1.85 cents) per Share and 46,929,731 Options, on 5 May 2025 on the terms as announced on 24 April 2025 ( Tranche 1 Securities ).

7

The Shares and Options were issued without shareholder approval from the Company’s 15% placement capacity pursuant to ASX Listing Rule 7.1.

ASX Listing Rules

ASX Listing Rules 7.1 allow the Company to issue new securities up to 15% of the existing capital of the Company in any 12-month period without the prior approval of Shareholders, unless one of the exceptions in ASX Listing Rule 7.2 applies. The Placement was within the Company’s available placement capacity under ASX Listing Rules 7.1.

Under ASX Listing Rule 7.4 an issue of securities will be treated as having been made with the approval of shareholders for the purposes of ASX Listing Rule 7.1 if the issue did not breach ASX Listing Rule 7.1 at the time and shareholders subsequently approve it. The Company now seeks Shareholder ratification of the issue pursuant to ASX Listing Rule 7.4 in order to retain as much flexibility as possible to issue additional equity securities into the future without having to obtain shareholder approval for such issues under Listing Rule 7.1.

If Resolution 1 is approved, the prior issue of Tranche 1 Securities will be excluded from the calculation of the number of equity securities the Company can issue without Shareholder approval under ASX Listing Rule 7.1. The Company will therefore have the flexibility, if required, to issue additional equity securities without the Tranche 1 Securities counting towards the 15% threshold for the purposes of ASX Listing Rule 7.1.

If this Resolution 1 is not approved, the prior issue of Tranche 1 Securities will be included in the calculation of the number of equity securities the Company can issue without Shareholder approval under ASX Listing Rules 7.1. The Company will therefore have the Tranche 1 Securities, as counting towards the 15% threshold for the purposes of ASX Listing Rule 7.1.

ASX Listing Rule 7.5 requires that the following information be provided to Shareholders for the purpose of obtaining Shareholder approval pursuant to ASX Listing Rule 7.4:

• (a) The Tranche 1 Shares were issued to professional and sophisticated investors who were introduced to the Company by GZ Family Holdings Pty Ltd and through the following brokers: 180 Markets, Bay Financial, and BW Equities. GZ Family Holdings Pty Ltd, a 16.52% substantial shareholder of the Company, were issued shares as part of the Placement. There were no other participants in the Placement that were investors required to be disclosed under ASX Guidance Note 21, such as related parties of the entity, member of the Company’s key management personnel, substantial shareholders of the Company, advisors of the Company and they have not been issued with more than 1% of the current issued capital

• (b) the number and class of securities issued were 46,929,731 Shares fully paid ordinary shares in the Company and 46,929,731 unlisted options, issued on 5 May 2025;

• (c)

• the Tranche 1 Shares were issued at a price of $0.0185 (1.85 cents) per Share;

• (d) the Options were issued to the investors under the Tranche 1 Placement, with an exercise price of 0.04 (4 cents), expiring 36 months from the date of issue. The material terms of Options are as set out in Annexure A;

• (e) the issue of Options will not raise any funds however, if any options are exercised in the future, the funds raised will be used to advance projects or working capital at the time of any such exercise; and

• (f) the purpose of the issue was to raise funds for general working capital, with specific use to be determined upon the board renewal that occurred on 2 May 2025.

• (g) the purpose of the issue of the free-attaching Options was to incentivise participants in the Placement.

Background

ASX Listing Rule 7.1 provides that a company must not, without shareholder approval, issue or agree to issue more securities during any 12 month period than that amount which represents 15% of the number of fully paid ordinary securities on issue at the commencement of that 12 month period.

If Resolution 2 is passed, the Company will issue the 67,448,645 Shares without using any of its placement capacity under Listing Rule 7.1 and retain the flexibility to make future issues of equity securities up to the 15% limit and raise approximately $1.2 before issue costs. If Resolution 2 is not passed, the Company will not be able to issue the 67,448,645 Shares under the Placement.

ASX Listing Rule 7.3 requires that the following information be provided to Shareholders for the purpose of obtaining Shareholder approval pursuant to ASX Listing Rule 7.1:

• (a) The Shares will be issued to professional and sophisticated investors who were introduced to the Company by GZ Family Holdings Pty Ltd and through the following brokers: 180 Markets, Bay Financial, and BW Equities.

There are no other participants in the Placement that are investors required to be disclosed under ASX Guidance Note 21, such as related parties of the entity, member of the Company’s key management personnel, substantial shareholders of the Company, advisors of the Company and they have not been issued with more than 1% of the current issued capital;

• (b) the number and class of securities issued are 67,448,645 fully paid ordinary shares in the Company;

• (d) the issue price of the Shares will be $0.0185 (1.85 cents) per share; and

• (e) the purpose of the issue was to raise funds for general working capital, with specific use to be determined upon the board renewal.

Board Recommendation

The Board believes that this Resolution is in the best interests of the Company and recommends that Shareholders vote in favour of this Resolution.

The Chair of the Meeting intends to vote undirected proxies in favour of this Resolution.

Voting Exclusions

Resolution 3: Approval to issue 67,448,645 Options as part of Tranche 2 Placement

Background

The Company is seeking Shareholder approval pursuant to ASX Listing Rule 7.1, to issue 67,448,645 Options to professional, sophisticated and other exempt investors who participated in the Tranche 2 Placement, on the terms as announced on 24 April 2025.

ASX Listing Rules

ASX Listing Rule 7.1 provides that a company must not, without shareholder approval, issue or agree to issue more securities during any 12 month period than that amount which represents 15% of the number of fully paid ordinary securities on issue at the commencement of that 12 month period.

The proposed issue of 67,448,645 Options does not fall within any of the relevant exceptions set out in Listing Rule 7.2 and exceeds the 15% limit in Listing Rule 7.1. It therefore requires the approval of the Company’s shareholders under Listing Rule 7.1.

ASX Listing Rules

Listing Rule 10.11 provides that unless one of the exceptions in Listing Rule 10.12 applies, a listed company must not issue or agree to issue equity securities to:

10.11.1 a related party;

• 10.11.2 a person who is, or was at any time in the 6 months before the issue or agreement, a substantial (30%+) holder in the company;

• 10.11.3 a person who is, or was at any time in the 6 months before the issue or agreement, a substantial (10%+) holder in the company and who has nominated a director to the board of the company pursuant to a relevant agreement which gives them a right or expectation to do so;

• 10.11.4 an associate of a person referred to in Listing Rules 10.11.1 to 10.11.3; or

• 10.11.5 a person whose relationship with the company or a person referred to in Listing Rules 10.11.1 to 10.11.4 is such that, in ASX’s opinion, the issue or agreement should be approved by its shareholders,

• unless it obtains the approval of its shareholders.

The issue falls within Listing Rule 10.11.1 and does not fall within any of the exceptions in Listing Rule 10.12. It therefore requires the approval of Shareholders under Listing Rule 10.11.

If Resolution 4 is passed, the Company will be able to proceed with the issue of the securities to Director Anthony May.

If Resolution 4 is not passed, the Company will not proceed with the issue of the securities to Anthony May.

If approvals are given under ASX Listing Rule 10.11, approvals are not required under ASX Listing Rule 7.1.

The following information is given under ASX Listing Rule 10.13 in respect of the proposed issues of Shares to Director under Resolutions 4:

• a) the proposed recipient is Mr Anthony May;

• b) the proposed recipient is a related parties of the Company, being a Director and thus fall into ASX Listing Rule 10.1.1;

• c) the number and class of securities to be issued are 540,541 Shares and 540,541 Options;

• d) the date by which the Company will issue the securities will be no later than one (1) month after the date of this Meeting (or such later date as may be approved by ASX).

• e) the issue price of the Shares will be $0.0185 (1.85 cents);

• f) the Options are to be issued, with an exercise price of 0.04 (4 cents), expiring 36 months from the date of issue. The material terms of Options are as set out in Annexure A;

Resolution 5: Approval to issue up to 54,054,054 Shares and 54,054,054 Options, as part of the Share Purchase Plan

Background

As announced on 24 April 2025, the Company proposes to raise up to $1 million by way of the issue up to 54,054,054 Shares in the Company at an issue price of $0.0185 (1.85 cents) ( SPP Shares ), together with up to 54,054,054 free-attaching Options on the basis of one Option for every one SPP Share subscribed for and issued under the SPP ( SPP Options ), exercisable at $0.04. expiring 36 months from the date of issue, as part of the Share Purchase Plan ( SPP ). The SPP Shares and SPP Options are together the " SPP Securities ".

By the date of the Meeting, the Company expects to have despatched to eligible shareholders at Prospectus for the proposed issue of the SPP Securities. The SPP offer is expected to open on 20 May 2025 and close on 23 June 2025, though the Company reserves the right to vary these dates.

ASX has granted to the Company a waiver from Listing Rule 7.3.9 to the extent necessary to permit the Company to not include in Resolution 5 a voting exclusion statement that excludes the votes of persons who may participate in the SPP, on the condition that the SPP is not underwritten, or if it is underwritten, the Company excludes any votes cast in favour of that resolution by any proposed underwriter or sub-underwriter of the SPP.

The SPP is not underwritten, however the Company has reserved the right to place any shortfall in the subscription for the SPP Securities under the SPP ( SPP Shortfall ). The Company has also reserved the right to accept oversubscriptions in the event that it receives valid applications for more than $1 million worth of Shares, however it must have sufficient placement capacity in order to do so. The Company may also elect to undertake a scale back, which it would do on a pro rata basis.

ASX Listing Rules

Broadly speaking, and subject to a number of exceptions, ASX Listing Rule 7.1 provides that a Company must not, without shareholder approval, issue or agree to issue more securities during any 12 month period than that amount which represents 15% of the number of fully paid ordinary securities on issue at the commencement of that 12 month period.

Listing Rule 7.2 (Exception 5) provides an exception to the Listing Rule 7.1 for the issue of securities pursuant to a share purchase plan. However, this exception is only available in relation to share purchase plans that satisfy all of the criteria of the exception, including that the share purchase plan must be conducted in accordance with ASIC Corporations (Share and Interest Purchase Plans) Instrument 2019/547 (the ASIC Instrument ). The Company's SPP does not fall within the ASIC Instrument as it includes the offer of both Shares and Options (rather than merely fully paid ordinary shares).

Accordingly, the proposed issue of up to 54,054,054 Shares and up to 54,054,054 Options under the SPP does not fall within the usual SPP exception and exceeds the 15% limit in Listing Rule 7.1. It therefore requires the approval of the Company’s shareholders under Listing Rule 7.1.

If Resolution 5 is passed, the Company will be able to proceed with the issue of the SPP Securities and their issue may be treated by the Company as having been excluded from the calculation of the number of equity securities that the Company can issue without Shareholder approval under Listing Rule 7.1. The Company will therefore have the flexibility, if required, to issue additional equity securities without the SPP Securities counting towards the 15% threshold for the purposes of ASX Listing Rule 7.1 over the 12-month period following the issue of the Placement Options.

If Resolution 5 is not passed the Company will not be able to issue the SPP Securities at all and will not be able to raise the $1 million targeted by the SPP.

If the Company is able to issue all of the SPP Shares (and assuming that Resolutions 2 and 4 are also passed enabling the Company to proceed with the issue of up to 67,989,186 Shares under tranche 2 of the Placement on or about the same time), the dilutionary effect of the SPP (if fully subscribed) is expected to be 9.91%. If the Company is not able to issue the tranche 2 Placement Shares, the dilutionary effect of the SPP is expected to be 7.88%.

ASX Listing Rule 7.3 requires that the following information be provided to Shareholders for the purpose of obtaining Shareholder approval pursuant to ASX Listing Rule 7.1:

12

• (a) the SPP Securities will be issued to eligible shareholders who subscribe for securities under the SPP. Eligible shareholders are those shareholders who have a registered address in Australia (as shown on the Share Register) as at the Record Date. To the extent there is a SPP Shortfall, the Company has reserved the right to place the SPP Shortfall at its discretion (refer to Resolution 6);

• (b) the number and class of securities issued are up to a maximum of 54,054,054 fully paid ordinary Shares and up to 54,054,054 Options (with Options to be issued on the basis of one free-attaching Option for every Share subscribed for and issued under the SPP), having an exercise price of 0.04 (4 cents) and expiring 36 months from the date of issue. The material terms of Options are as set out in Annexure A;

• (c) the date by which the Company will issue the SPP Securities will be no later than three (3) months after the date of this Meeting (to the extent permitted by any ASX waiver or modification of the Listing Rules). The Company expects the SPP Securities to be issued on or around 27 June 2025, as set out in its indicative timetable announced on 24 April 2025;

• (d) the issue price of the Shares will be $0.0185 (1.85 cents) per share. The Options are free-attaching and will therefore be issued at a nil issue price.

• (e) the Company will raise up to $1 million from the issue of the SPP Shares which will be used for general working capital, with specific use to be determined upon the board renewal, and to fund costs of the offer;

• (f) the issue of Options will not raise any funds however, if any options are exercised in the future, the funds raised will be used to advance projects or working capital at the time of any such exercise; and

• (g) the purpose of the proposed issue of the free-attaching Options is to incentivise participants in the Placement.

Board Recommendation

The Board believes that this Resolution is in the best interests of the Company and recommends that Shareholders vote in favour of this Resolution, for the following reasons:

• allowing the SPP to proceed enables the Company's existing Shareholders to have the opportunity to participate in fundraising on the same terms offered under the Placement; and

• it allows the Company to raise up to an additional $1 million.

The Chair of the Meeting intends to vote undirected proxies in favour of this Resolution.

Voting Exclusions

The Company has been granted a waiver by ASX under Listing Rule 7.3.9 to permit any person who has an interest in Resolution 5 and ordinarily excluded from voting in favour of this Resolution to vote, on the condition that the Company excludes any votes cast on this Resolution by any proposed underwriter or sub-underwriter of the SPP (which there is none).

Resolution 6 & 7: Approve the participation of Director John Kelly (or his nominee(s)) and Director Partick Cook (or his nominee(s)) in the Share Purchase Plan

Background

As part of the SPP, the Company is seeking Shareholder approval pursuant to ASX Listing Rule 10.11, to issue a total of 2,162,162 Shares in the Company at an issue price of $0.0185 (1.85 cents) and 2,162,162 Options exercisable at $0.04 expiring 36 months from the date of issue, to Mr John Kelly, Managing Director and Mr Patrick Cook, a Non-Executive Director, on the terms and conditions set out below. The details of the Shares proposed to be issued under Resolutions 6 & 7 are as follows:

Resolution	Name of Director	Number of Shares	Issue Price	Options	Fund Raised
Resolution 6	Mr John Kelly	1,621,622	$0.0185	1,621,622	$30,000
Resolution 7	Mr Patrick Cook	540,541	$0.0185	540,541	$10,000
Total		2,162,162		2,162,162	$40,000

ASX Listing Rules

Listing Rule 10.11 provides that unless one of the exceptions in Listing Rule 10.12 applies, a listed company must not issue or agree to issue equity securities to:

• 10.11.1 a related party;

• 10.11.2 a person who is, or was at any time in the 6 months before the issue or agreement, a substantial (30%+) holder in the company;

• 10.11.3 a person who is, or was at any time in the 6 months before the issue or agreement, a substantial (10%+) holder in the company and who has nominated a director to the board of the company pursuant to a relevant agreement which gives them a right or expectation to do so;

• 10.11.4 an associate of a person referred to in Listing Rules 10.11.1 to 10.11.3; or

• 10.11.5 a person whose relationship with the company or a person referred to in Listing Rules 10.11.1 to 10.11.4 is such that, in ASX’s opinion, the issue or agreement should be approved by its shareholders,

• unless it obtains the approval of its shareholders.

The issue falls within Listing Rule 10.11.1 and does not fall within any of the exceptions in Listing Rule 10.12. It therefore requires the approval of Shareholders under Listing Rule 10.11.

If Resolutions 6 & 7 are passed, the Company will be able to proceed with the issue of securities to Directors John Kelly and Patrick Cook. If any of Resolution 6 & 7 are not passed, the Company will not proceed with the issue, of securities to the applicable parties.

If approvals are given under ASX Listing Rule 10.11, approvals are not required under ASX Listing Rule 7.1.

The following information is given under ASX Listing Rule 10.13 in respect of the proposed issues of Shares to Director John Kelly and Patrick Cook:

• (a) the proposed recipients are Directors John Kelly and Patrick Cook;

• (b) Mr John Kelly and Mr Patrick Cook are related parties of the Company, being Directors and thus fall into ASX Listing Rule 10.1.1.

• (c) the number and class of securities to be issued are as described in the table above;

• (d) the date by which the Company will issue the securities will be no later than one (1) month after the date of this Meeting (or such later date as may be approved by ASX).

• (e) the issue price of the Shares will be $0.0185 (1.85 cents);

• (f) the Options are to be issued, with an exercise price of 0.04 (4 cents), expiring 36 months from the date of issue. The material terms of Options are as set out in Annexure A;

• (g) the issue of options will not raise any funds however, if any options are exercised in the future, the funds raised will be used to advance projects or working capital at the time of any such exercise;

• (j) the purpose of the proposed issue of the free-attaching Options is to incentivise participants in the Placement.

Board Recommendation

The Board (with Mr John Kelly and Mr Patrick Cook abstaining with respect to their respective issue), believes that these Resolutions are in the best interests of the Company and recommends that Shareholders vote in favour of these Resolutions.

The Chair of the Meeting intends to vote undirected proxies in favour of Resolutions 6 & 7.

Voting Exclusions

A voting exclusion statement for these resolutions is set out in Note 6 above.

Resolution 8: Approval to issue up to 54,054,054 Shares and 54,054,054 Options, as part of the SPP Shortfall Placement

Background

As noted above, the Company is seeking to raise funds through an SPP to raise up to a maximum of $1,000,000. The SPP is not underwritten, and accordingly, there is no guarantee that it will be fully subscribed. If it is not fully subscribed, the Company will offer any SPP Shortfall by way of a placement participants identified by the Company.

This Resolution seeks shareholder approval to place the SPP Shortfall. The company is therefore seeking Shareholder approval pursuant to ASX Listing Rule 7.1, to issue as the case may be, up to 54,054,054 Shares in the Company at an issue price of $0.0185 (1.85 cents) and 54,054,054 free-attaching Options, exercisable at $0.04. expiring 36 months from the date of issue, ( SPP Shortfall Securities ).

Both the offer of the SPP Securities and the SPP Shortfall Securities will be made pursuant to a Prospectus to be despatched on or about 20 May 2025. Accordingly, the offer of the Shortfall Securities is open to both retail and exempt investors.

ASX Listing Rules

Broadly speaking, and subject to a number of exceptions, ASX Listing Rule 7.1 provides that a company must not, without shareholder approval, issue or agree to issue more securities during any 12 month period than that amount which represents 15% of the number of fully paid ordinary securities on issue at the commencement of that 12 month period.

The proposed issue of the SPP Shortfall Securities does not fall within any of the relevant exceptions set out in Listing Rule 7.2 and exceeds the 15% limit in Listing Rule 7.1. It therefore requires the approval of the Company’s shareholders under Listing Rule 7.1.

If Resolution 6 is passed, the Company will be able to proceed with the issue of the SPP Shortfall Securities to participants other than 'Eligible Shareholders' for the purposes of the SPP, and the issue of the SPP Shortfall Securities may be treated by the Company as having been excluded from the calculation of the number of equity securities that the Company can issue without Shareholder approval under Listing Rule 7.1. The Company will therefore have the flexibility, if required, to issue additional equity securities without the SPP Securities counting towards the 15% threshold for the purposes of ASX Listing Rule 7.1 over the 12-month period following the issue of the SPP Shortfall Securities.

If Resolution 6 is not passed, and there is an SPP Shortfall, the Company will not be able to issue the SPP Shortfall Securities, which would limit the Company's ability to meet its funding raising target of a further $1 million from the SPP. The Company will not know the extent of any SPP Shortfall (if any), until the closing date for the SPP (being Monday 23 June 2025). However, its dilutionary impact will be limited to no more than the dilutionary impact of the SPP as set out above in respect of Resolution 4.

ASX Listing Rule 7.3 requires that the following information be provided to Shareholders for the purpose of obtaining Shareholder approval pursuant to ASX Listing Rule 7.1:

• (a) the Company has not yet identified who the participants of any SPP Shortfall Securities will be. However, they will be persons other than 'Eligible Shareholders' for the purposes of the SPP (being those Shareholders with a registered address in Australia as at the Record Date). Further, as the Company is offering the SPP and the SPP Shortfall Securities under a Prospectus, the SPP Shortfall Securities may be offered to retail investors, as well as to professional, sophisticated and other exempt investors, who do not participate in the SPP;

• (b) the number and class of securities issued are up to 54,054,054 Shares and up to 54,054,054 Options (with Options to be issued on the basis of one free-attaching Option for every Share subscribed for and issued under the Shortfall Offer);

• (c) the date by which the Company will issue the SPP Securities will be no later than three (3) months after the date of this Meeting (to the extent permitted by any ASX waiver or modification of the Listing Rules);

• (d) the issue price of the Shares will be $0.0185 (1.85 cents) per share. The Options are free-attaching and will therefore be issued at a nil issue price.

15

• (e) the purpose of the issue of the SPP Shortfall Securities it to raise funds and enable the Company to raise its target of $1 million under or in connection with the SPP. The funds will be used for general working capital, with specific use to be determined upon the board renewal, and to fund costs of the offer;

• (f) the issue of Options will not raise any funds however, if any options are exercised in the future, the funds raised will be used to advance projects or working capital at the time of any such exercise; and

• (g) the purpose of the proposed issue of the free-attaching Options is to incentivise participants in the Placement.

Board Recommendation

The Board believes that this Resolution is in the best interests of the Company and unanimously recommends that Shareholders vote in favour of this Resolution, for the following reasons:

• allowing the SPP Shortfall Securities may enable the Company to raise its $1 million target in the event that the SPP is not fully subscribed.

The Chair of the Meeting intends to vote undirected proxies in favour of this Resolution.

Voting Exclusions

A voting exclusion statement for this resolution is set out in Note 6 above.
