Announcement PDF Rules 4.7.3 and 4.10.3 ASX Listing Rules Appendix 4G (current at 17/7/2020) Page 1 Appendix 4G Key to Disclosures Corporate Governance Council Principles and Recommendations Name of entity IMPACT MINERALS LIMITED ABN/ARBN Financial year ended: 51 119 062 261 30 JUNE 2026 Our corporate governance statement1 for the period above can be found at:2 ☐ These pages of our annual report: ☒ This URL on our website: https://impactminerals.com.au/esg The Corporate Governance Statement is accurate and up to date as at 30 June 2026 and has been approved by the board. The annexure includes a key to where our corporate governance disclosures can be located.3 Date: 21 October 2026 Name of authorised officer authorising lodgement: Arron Canicais (Company Secretary) 1 “Corporate governance statement” is defined in Listing Rule 19.12 to mean the statement referred to in Listing Rule 4.10.3 which discloses the extent to which an entity has followed the recommendations set by the ASX Corporate Governance Council during a particular reporting period. Listing Rule 4.10.3 requires an entity that is included in the official list as an ASX Listing to include in its annual report either a corporate governance statement that meets the requirements of that rule or the URL of the page on its website where such a statement is located. The corporate governance statement must disclose the extent to which the entity has followed the recommendations set by the ASX Corporate Governance Council during the reporting period. If the entity has not followed a recommendation for any part of the reporting period, its corporate governance statement must separately identify that recommendation and the period during which it was not followed and state its reasons for not following the recommendation and what (if any) alternative governance practices it adopted in lieu of the recommendation during that period. Under Listing Rule 4.7.4, if an entity chooses to include its corporate governance statement on its website rather than in its annual report, it must lodge a copy of the corporate governance statement with ASX at the same time as it lodges its annual report with ASX. The corporate governance statement must be current as at the effective date specified in that statement for the purposes of Listing Rule 4.10.3. Under Listing Rule 4.7.3, an entity must also lodge with ASX a completed Appendix 4G at the same time as it lodges its annual report with ASX. The Appendix 4G serves a dual purpose. It acts as a key designed to assist readers to locate the governance disclosures made by a listed entity under Listing Rule 4.10.3 and under the ASX Corporate Governance Council’s recommendations. It also acts as a verification tool for listed entities to confirm that they have met the disclosure requirements of Listing Rule 4.10.3. The Appendix 4G is not a substitute for, and is not to be confused with, the entity's corporate governance statement. They serve different purposes and an entity must produce each of them separately. 2 Tick whichever option is correct and then complete the page number(s) of the annual report, or the URL of the web page, where your corporate governance statement can be found. You can, if you wish, delete the option which is not applicable. 3 Throughout this form, where you are given two or more options to select, you can, if you wish, delete any option which is not applicable and just retain the option that is applicable. If you select an option that includes “OR” at the end of the selection and you delete the other options, you can also, if you wish, delete the “OR” at the end of the selection. See notes 4 and 5 below for further instructions on how to complete this form.
