EXPLANATORY NOTES

Item 6.F. Disclosure of a registrant’s action to recover erroneously awarded compensation.

As indicated in the Form 20-F/A filed by the Company on October 6, 2025, the Company restated its financial statements for the year ended June 30, 2024 to correct an error. The Company’s Policy for the Recovery of Erroneously Awarded Compensation (the “Clawback Policy”) requires the repayment of certain erroneously awarded incentive-based compensation paid to current or former executive officers in connection with a restatement of financial statements if such compensation exceeded the amount that such executive officers otherwise would have received had it been determined based on the restated financial statements. No Clawback Eligible Incentive Compensation (as such term is defined in the Clawback Policy) was paid during the requisite look-back period and as a result, the Company concluded that no compensation is required to be recouped as a result of the restatement.

Item 18. Financial Statements

The financial statements of Tanbreez required by Rule 3-09 of Regulation S-X are provided as Exhibit 15.1 hereto and incorporated herein by reference.

Item 19. Exhibits

List all exhibits filed as part of the registration statement or annual report, including exhibits incorporated by reference.
