Item 8.01 Other Events.

On July 17, 2025, the Board of Directors (the "Board") of DynaResource, Inc. (the "Company") authorized Company management to commence a legal process under Mexican law referred to as "amparo" in order to protect the Company's rights with respect to the following nine mining concessions (the "Impacted Concessions") related to the Company's San José de Gracia mine project:

During a review by the Company's executive management of information related to the Company's mining concessions, the Company became aware that a public website hosted by the Mexican Secretariat of Economy (Secretaría de Economía) (the "Website") includes information indicating that the Impacted Concessions are not currently active. Although the Website also indicates that the published information is for informational purposes only and that such information is not officially valid, and the Company has not received any formal notification from any Mexican authority asserting adverse action that could result in the nullification or cancellation of the rights under any of the Impacted Concessions, the Board determined it prudent, as a precautionary measure, to authorize the Company to commence the amparo process to challenge the inactive status of the Impacted Concessions indicated on the Website and any related administrative action(s) taken in violation of the Company's due process rights.

The Company continues to review information available to it and intends to take appropriate action to protect its rights to the Impacted Concessions; however, no assurance can be provided regarding the outcome of its actions or the availability of the Impacted Concessions to the Company in the future.
