Adamera closes $815,000 non-brokered placement

Vancouver, British Columbia – August 20, 2026 – TheNewswire – Adamera Minerals Corp. (TSX-V: ADZ; OTC: DDNFF) ("Adamera" or the "Company") announces today it has closed the non-brokered private placement as announced on July 29, 2026 and August 11, 2026.

The Company raised $815,000 from the sale of 8,150,000 Units (“Units”) at $0.10 per Unit. Each unit consists of one common share and one warrant. Each warrant is exercisable at a price of $0.15 for a period of three years from the date of issuance. If the closing market price of the Company's common shares on the TSX Venture Exchange (the “Exchange”) is $0.20 or more over a period of 10 consecutive trading days at any time after the date that is four months and one day after the respective closing, the warrants will expire on the 30th day (the "Accelerated Expiry Date") after the 10 consecutive trading days at or above $0.20 unless exercised by the holder on or before the Accelerated Expiry Date (the “Accelerated Provision”).

A director and an officer of the Company together purchased or acquired direction and control over a total of 650,000 Units under the private placement. The placement to these people constitutes a “related party transaction” within the meaning of the Exchange Policy 5.9 and Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions (“MI 61-101”) adopted in the Policy. The Company will rely on exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a) of MI 61-101 in respect of related party participation in the placement as neither the fair market value (as determined under MI 61-101) of the subject matter of, nor the fair market value of the consideration for, the transaction, insofar as it involved the related parties, exceeded 25% of the Company's market capitalization (as determined under MI 61-101).

All securities associated with the private placement are subject to a four-month hold and will become free trading on December 21, 2026. No finder’s fee was paid for this private placement. The Company intends to use the proceeds of the private placement for exploration work on its various tungsten, gold and copper projects and for general working capital.
