OTCQX: DYNR WWW.DYNARESOURCE.COM DynaResource Announces Favorable Ruling in Amparo Proceedings

IRVING, TX / August 5, 2026 / DYNR-DynaResource, Inc. (OTCQX:DYNR) (“DynaResource”, or “the Company”, inclusive of its subsidiaries) is pleased to announce that the Federal District Court in Mexico (the “Court”) has issued a favorable ruling in the Amparo proceedings by the Company’s subsidiary, DynaResource de México, S.A. de C.V. ("DynaMéxico”), relating to eight mining concessions (the "Impacted Concessions”) associated with the San José de Gracia Project in Mexico.

The Court granted constitutional protection (“Amparo”) to the Company, concluding that DynaResource was not properly notified of the administrative proceedings that resulted in the claimed cancellation of the mining concessions posted to the Mexican Secretariat of Economy’s (Secretaría de Economía) website, and, as a result, was denied its constitutional right to due process and an opportunity to defend its interests. The Court further ordered the authorities to recommence the notification process in accordance with applicable legal requirements before continuing any administrative proceedings.

"This ruling represents an important procedural milestone in protecting the Company's legal rights in Mexico," stated Rohan Hazelton, President and CEO of DynaResource. "While the judgment is not yet final and remains subject to appeal by the relevant authorities, we are encouraged that the Court recognized the Company's fundamental right to due process. We will continue to protect our interests while remaining focused on operational improvements and long-term value creation at San José de Gracia."

The ruling is subject to the applicable appeal process under Mexican law, and the respondent authorities may seek review of the decision. The Company, together with its legal counsel, will continue to monitor the proceeding and will provide further updates as material developments occur.

As previously disclosed on July 18, 2025, the Company initiated the Amparo proceeding to protect its legal rights in connection with the inactive claim on its Impacted Concessions. While this favorable ruling does not finally resolve the underlying administrative matter, it restores the Company's procedural rights and requires the authorities to comply with constitutional due process requirements before any further administrative action may be taken.

The ruling covers the following mining concession titles held by DynaMéxico:
