Data importing, compilation, integration and analysis began when key staff returned from annual leave between 20 January and 28 January 2025. Analysis was finalised on 5 February 2025 when management drafted the announcement. See note for Q4 for details. 4. If KAL first became aware of the information referred to in question 1 before the date of the Announcement, did KAL make any announcement prior to that date which disclosed the information? If not, please explain why the information was not released to the market at an earlier time, commenting specifically on when you believe KAL was obliged to release the information under Listing Rules 3.1 and 3.1A and what steps KAL took to ensure that the information was released promptly and without delay. Please answer separately for each of the items in question 1 above and provide details of the prior announcement if applicable. KAL did not make a prior announcement in relation to: • • • The Lighthorse Results - which included those results for: Drill Hole KGAC24152; and Drill Hole KGAC24153’. Information prior to release of the announcement was incomplete and the announcement could not be finalised earlier. Data importing, integration with previously announced results, analysis and interpretation was undertaken immediately upon return of key staff members between 20 January and 28 January 2025. The staggered return of the results, including the return of key multi-element datasets on 24 January 2025 (immediately prior to the Australia Day long weekend), also precluded substantial progress, as the multi-element data is required to undertake and complete a detailed interpretation of the assay results. Essential lithogeochemical analysis of multi-element datasets was completed on 3 February 2025 and a thorough review of textural features of drill chips and their interpretation was also completed on 3 February 2025. This data is not for release but provides the Company additional background information and certainty regarding published results. Inconsistencies and differences between these analyses were interrogated and resolved on 4 and 5 February 2025 during writing of earlier drafts, enabling satisfactory definition of the gold supergene blanket distribution crucial to the Lighthorse interpretation and drafting of the announcement. Other preparatory activities that were initially a focus but were abandoned for timeliness (and are still outstanding) include generation of a geological (lithological and structural) interpretation over the Lighthorse prospect area and integration with lithogeochemical and textural findings. A geological interpretive map was ultimately excluded due to uncertainties from low drill density, some apparent minor lithogeochemical and textural inconsistencies, and lack of diagnostic features in aeromagnetic datasets. These will be addressed upon the Company’s satisfaction of sufficient certainty following collection of greater volumes of data on completion of future drill programs. Final drafts were under review as per standard Company procedure when we became aware of the share price and volume increase. As the announcement was not ready for release at that moment, KAL notified and consulted with ASX before voluntarily requesting a trading halt. 5. Please confirm that KAL is in compliance with the Listing Rules and, in particular, Listing Rule 3.1. Confirmed 6. Please confirm that KAL’s responses to the questions above have been authorised and approved in accordance with its published continuous disclosure policy or otherwise by its board or an officer of KAL with delegated authority from the board to respond to ASX on disclosure matters. Confirmed – This response has been approved by the Board.

G. The definition of “aware” in Chapter 19 of the Listing Rules, which states that: “an entity becomes aware of information if, and as soon as, an officer of the entity (or, in the case of a trust, an officer of the responsible entity) has, or ought reasonably to have, come into possession of the information in the course of the performance of their duties as an officer of that entity.” H. Section 4.4 in Guidance Note 8 Continuous Disclosure: Listing Rules 3.1 – 3.1B titled “When does an entity become aware of information?” ASX Limited [[Listings]] #10861776v1 ASX Customer Service Centre 131 279 | asx.com.au I. Listing Rule 3.1A, which sets out exceptions from the requirement to make immediate disclosure as follows. “3.1A Listing rule 3.1 does not apply to particular information while each of the following is satisfied in relation to the information: 3.1A.1 J. One or more of the following 5 situations applies: • It would be a breach of a law to disclose the information; • The information concerns an incomplete proposal or negotiation; • The information comprises matters of supposition or is insufficiently definite to warrant disclosure; • The information is generated for the internal management purposes of the entity; or • The information is a trade secret; and 3.1A.2 The information is confidential and ASX has not formed the view that the information has ceased to be confidential; and 3.1A.3 A reasonable person would not expect the information to be disclosed.” The concept of “confidentiality” detailed in section 5.8 of Guidance Note 8 Continuous Disclosure: Listing Rules 3.1 – 3.1B. In particular, the Guidance Note states that: “Whether information has the quality of being confidential is a question of fact, not one of the intention or desire of the entity. Accordingly, even though an entity may consider information to be confidential and its disclosure to be a breach of confidence, if it is in fact disclosed by those who know it, then it is no longer a secret and it ceases to be confidential information for the purposes of this rule.” Request for information Having regard to the above, ASX asks KAL to respond separately to each of the following questions: 1.
