IRVING, TX -- (Marketwired) -- 06/21/13 -- (OTCQB: DYNR) -- DynaResource, Inc. ("DynaUSA", and "the Company") is pleased to announce that its 100 % owned subsidiary, Mineras de DynaResource S.A. de C.V. ("Mineras") has entered into an Exploitation Amendment Agreement with DynaResource de Mexico S.A. de C.V. ("DynaMexico"), the 100 % owner of the San Jose de Gracia Property in northern Sinaloa, Mexico ("SJG", and the "SJG Property").

The Exploitation Amendment Agreement ("EAA") grants to Mineras the right to finance, explore, develop and exploit the SJG Property, in exchange for: (A) Reimbursement of all costs associated with financing, maintenance, exploration, development and exploitation of the SJG Property, which costs are to be charged and billed by Mineras to DynaMexico; and, (B) After Item (A) above, the receipt by Mineras of 75 % of gross receipts received by DynaMexico from the sale of all minerals produced from SJG, to the point that Mineras has received 200 % of its advanced funds; and, (C) After Items (A) and (B) above; the receipt by Mineras of 50 % of all gross receipts received by DynaMexico from the sale of all minerals produced from SJG, and throughout the term of the EAA; and, (D) In addition to Items (A), (B), and (C) above, Mineras shall receive a 2.5 % NSR on all minerals sold from SJG over the term of the EAA.

The Exploitation Amendment Agreement is dated May 15, 2013, and was ratified on the same date in the presence of a Notary Public in Mazatlan, Sinaloa for giving full legal effect. The EAA is the third and latest Amendment to the original Contract Mining Services and Mineral Production Agreement (the "Operating Agreement"), which was previously entered into by Mineras with DynaMexico in April 2005, wherein Mineras was named the Exclusive Operating Entity at SJG. The Operating Agreement was previously amended in September 2006 (the "First Amendment"), and amended again at July 15, 2011 (the "Second Amendment"). The Term of the Second Amendment is 20 years, and the EAA provides for the continuation of the 20 Year Term from the date of the Second Amendment (July 15, 2011).

Mr. K.D. Diepholz, Chairman-CEO of DynaUSA, said: "I am pleased to report the signing of the Exploitation Amendment Agreement between DynaMexico and Mineras. The provisions of the EAA, and including the continued exclusive operating arrangements granted to Mineras, provide for a clear path forward for Mineras to advance, develop and exploit the SJG Property. And, the provisions of the EAA provide a fair, competitive opportunity to Mineras and DynaUSA (which continues to provide cash advances to Mineras), as Mineras and DynaUSA have maintained and advanced the SJG Property in recent years. In addition, with operations at SJG continuing under Mineras, the SJG Property is well positioned to receive the benefits and continuing support from professional and strategic relationships developed in Sinaloa State and Mexico which DynaUSA, its subsidiaries and personnel have established over the past 10 years. With the EAA in full force and effect, and recognizing that DynaUSA owns 100 % of Mineras, I expect DynaUSA and its shareholders to realize the benefits of future advance and development of the SJG Property, which is now being planned by Mineras."

IMPORTANT CAUTIONARY NOTE REGARDING CANADIAN DISCLOSURE STANDARDS

The Company is an "OTC Reporting Issuer" as that term is defined in BC Instrument 51-509, Issuers Quoted in the U.S. Over-the-Counter Markets, promulgated by the British Columbia Securities Commission. Accordingly, certain disclosure in this news release or other disclosure provided by the Company has been prepared in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of United States securities laws. In Canada, an issuer is required to provide technical information with respect to mineralization, including reserves and resources, if any, on its mineral exploration properties in accordance with Canadian requirements, which differ significantly from the requirements of the United States Securities and Exchange Commission (the "SEC") applicable to registration statements and reports filed by United States companies pursuant to the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended. As such, information contained in this news release or other disclosure provided by the Company concerning descriptions of mineralization under Canadian standards may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the SEC and not subject to Canadian securities legislation. This news release or other disclosure provided by the Company may use the terms "measured mineral resources", "indicated mineral resources" and "inferred mineral resources". While these terms are recognized and required by Canadian regulations (under National Instrument 43-101, Standards of Disclosure for Mineral Projects), the SEC does not recognize them. United States investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted to reserves. In addition, "inferred mineral resources" have a great amount of uncertainty as to their existence and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian securities legislation, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, although they may form, in certain circumstances, the basis of a "preliminary economic assessment" as that term is defined in National Instrument 43-101, Standards of Disclosure for Mineral Projects. U.S. investors are cautioned not to assume that part or all of an inferred mineral resource exists, or is economically or legally mineable.

Certain assumptions have been made regarding the Company's plans at the San Jose de Gracia property. Many of these assumptions are based on factors and events that are not within the control of DynaResource and there is no assurance they will prove to be correct. Such factors include, without limitation: capital requirements, fluctuations in the international currency markets and in the rates of exchange of the currencies of the United States and Mexico; price volatility in the spot and forward markets for commodities; discrepancies between actual and estimated production, between actual and estimated reserves and resources and between actual and estimated metallurgical recoveries; changes in national and local governments in any country which DynaResource currently or may in the future carry on business; taxation; controls; regulations and political or economic developments in the countries in which DynaResource does or may carry on business; the speculative nature of mineral exploration and development, including the risks of obtaining necessary licenses and permits, diminishing quantities or grades of reserves; competition; loss of key employees; additional funding requirements; actual results of current exploration or reclamation activities; changes in project parameters as plans continue to be refined; accidents; labor disputes; defective title to mineral claims or property or contests over claims to mineral properties. In addition, there are risks and hazards associated with the business of mineral exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold bullion losses (and the risk of inadequate insurance or inability to obtain insurance, to cover these risks) as well as those risks referenced in the Annual Report for DynaResource available at www.sec.gov.
