This Amendment No. 7 to Schedule 13D (this “Amendment”) relates to shares of Series E Convertible Preferred Stock, which shares are convertible on a one-to-one basis into shares of common stock, par value $0.01 per share (the “Common Stock”), of DynaResource, Inc., a Delaware corporation (the “Issuer”). This Amendment amends the Schedule 13D, as previously amended (as amended, the “Schedule 13D”), filed with the Securities and Exchange Commission (“SEC”) by Golden Post Rail, LLC, a Texas limited liability company (“Golden Post”), Matthew K. Rose, a United States citizen and MKR 2022 Grantor Retained Annuity Trust by furnishing the information set forth below. Except as otherwise specified in this Amendment, all previous Items are unchanged. Capitalized terms used herein which are not defined herein have the meanings given to them in the Schedule 13D, as previously amended, filed with the SEC.

Item 3. Source and Amount of Funds or other Consideration

Item 3 is hereby amended and supplemented as follows:

“Between August 16, 2023 and December 4, 2023, Mr. Rose expended an aggregate of approximately $497,416.76 of his personal funds to purchase 200,000 shares of Common Stock in the open market at various purchase prices.

On June 26, 2024, the Issuer entered into a Stock Purchase Agreement (the “SPA”) with Golden Post. The SPA is the definitive agreement contemplated by the Memorandum of Understanding (the “MOU”) dated June 3, 2024 (as disclosed in the Issuer’s Form 8-K filed with the Securities Exchange Commission on June 7, 2024) with Ocean Partners Holdings Limited (“Ocean Partners”) to memorialize Golden Post’s intent to purchase shares of stock from the Issuer for a purchase price of $2,500,000 in a private placement transaction.

Pursuant to the SPA, as discussed below, the Issuer adopted a Certificate of Designations creating the Series E Convertible Preferred Stock (the “Series E Preferred Stock”) that is junior to the Issuer’s outstanding Series C and Series D Preferred Stock and pari passu with the Issuer’s Common Stock. On June 27, 2024, the Issuer issued 1,552,795 shares of Series E Preferred Stock to Golden Post in exchange for a payment of $2,500,000, at a price of $1.61 per share as contemplated by the MOU and the SPA.

As contemplated by the MOU, at closing of the SPA, Golden Post waived certain preemptive and antidilution rights that would otherwise have been triggered by stock issuances contemplated by the MOU and employment-related transactions undertaken contemporaneously with the MOU.

The foregoing summary is qualified in its entirety by reference to the full text of the SPA, a copy of which is attached hereto as Exhibit 99.21 and incorporated herein in its entirety by reference. The representations, warranties and covenants contained in the SPA were made only for purposes of the SPA and as of specific dates, were solely for the benefit of the parties to the SPA, and may be subject to limitations agreed upon by the contracting parties.”
