DIAMCOR ANNOUNCES APPLICATION FOR A MANAGEMENT CEASE TRADE ORDER

Due to continuing delays in completing financing objectives and associated operational and audit-related delays, Diamcor Mining Inc. will be unable to file its audited financial statements and corresponding management's discussion and analysis for the year ended March 31, 2025 on or before the prescribed filing deadline of July 29, 2025, as required by National Instrument 51-102 (Continuous Disclosure Obligations). The company's South African auditor, PricewaterhouseCoopers, and its Canadian auditor, MNP LLP, require more time to complete the preparation, reviews and audit in respect of the financial disclosure. The delay has been caused by the inability of the company to complete its financing objectives under way and the associated financing transactions due to the well-documented industry-wide supply chain disruptions and the resulting uncertainty surrounding the impact of U.S. imposed tariffs, compounded by the recent actions undertaken by a major creditor, Tiffany & Co. Canada, to enforce its security against all of the company's present and after acquired personal property and all shares held by the company in the capital of its subsidiary DMI Diamonds South Africa Pty. Ltd., as previously announced in the company's news release on June 13, 2025. These issues have disrupted the company's South African operations, which have also contributed to the delays in completing the South Africa portion of the company's annual audit work.

The company is working to complete the financing objectives under way, provide the additional submissions and related items to its auditor, and complete the audit of the financial statements for the year ended March 31, 2025. In this regard, the company has formulated the following remediation plan:

• Finalize arrangements with Tiffany to defer any formal insolvency proceedings to enable the company to complete its financing objectives (target completion: Aug. 15, 2025);
• Complete financing objectives (target completion of Aug. 29, 2025);
• Complete delivery of required submissions and related items to the company's South African and Canadian auditors (target completion: Sept. 2, 2025);
• Complete draft annual filings for review and approval by the company (target completion: Sept. 23, 2025);
• Complete final approval and filing of annual filing (target completion: Sept. 26, 2025).

Based on the foregoing, the company anticipates that it will be in a position to file its financial disclosure before Sept. 29, 2025. The company confirms that it will comply with the alternative information guidelines included in National Policy 12-203 (Management Cease Trade Orders) for so long as it remains in default of a specified requirement.

The company has filed an application with the B.C. Securities Commission and the Alberta Securities Commission requesting that they issue a management cease trade order against the company's directors, officers and/or insiders instead of a cease trade order against the company and all of its securityholders.
