KELOWNA, June 18, 2024 - Diamcor Mining Inc. (TSXV:DMI)(OTCQB:DMIFF)(FRA:DC3A), ("Diamcor" or the "Company"), an established diamond mining company focused on developing a supply of ethically sourced, non-conflict, natural rough diamonds to select diamantaires and luxury retailers, announces today that, further to its news release of June 4, 2024, the Company is seeking to extend the closing of the second tranche of its non-brokered revised private placement (the "Offering"). The Company previously indicated that the original Offering, the terms of which can also be found in its news release of May 1, 2024, would be oversubscribed and is seeking additional time to accommodate and finalize the documentation and related required items for several additional interested investors. The second and final tranche of the Offering is now expected to close on or before June 27, 2024, and remains subject to final approval by the TSX Venture Exchange.

As previously announced, the first tranche consisted of 28,120,000 units at a price of CND $0.05 per unit for proceeds of $1,406,000.00. Each unit consists of one Class "A Common share in the authorized capital of the Company (a "Share"), and one non-transferable share purchase warrant (a "Warrant"). Each Warrant will entitle the holder to acquire one additional Class "A" Common share at an exercise price of CND $0.075 for a period of 36 months following the close of the first tranche.

Proceeds from the offering will be used for the continued advancement of the Company's Krone-Endora at Venetia Project (the "Project), the work programmes currently underway, the announced efforts surrounding drilling and bulk sampling on the greater portions of the Project, the advancement of discussions on potential acquisitions of additional opportunities aimed at increasing long-term shareholder value and added growth, and for general corporate purposes. The Company also plans to continue to advance ongoing discussions with financiers and industry related parties on additional funding scenarios which may be beneficial in further supporting the above noted objectives aimed at increasing long-term shareholder value and added growth.

All private placements are subject to regulatory and/or final approval of the TSX Venture Exchange along with completion of all definitive documentation and filings as required. Securities issued pursuant to the Offering are subject to a hold period of four months plus one day following the date of issuance.

The securities sold in the Offering have not been registered under the United States Securities Act of 1933, as amended, or any state securities laws and may not be offered or sold in the United States absent registration under such Act or an applicable exemption from such registration requirements. This press release shall not constitute an offer to sell or the solicitation of an offer to buy securities in the United States or any other jurisdiction nor shall there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction.
