FOR IMMEDIATE RELEASE 

DynaResource de Mexico receives Permission for the Rehabilitation and Operation of the Pilot Mill Facility at San Jose de Gracia

(Permission Issued by the Federal Environmental Authority in Mexico-SEMARNAT)

Irving, Texas (June 28, 2013) OTCQB: DYNR – DynaResource, Inc. (“DynaUSA”, and “the Company”) is pleased to announce that DynaResource de Mexico S.A. de C.V. (“DynaMexico”), the 100 % owner of the San Jose de Gracia Property in northern Sinaloa, Mexico (“SJG”), received on June 17, 2013 from the Secretaria de Medio Ambiente Y Recursos Naturales, the Federal Environmental Authority in Mexico (“SEMARNAT”), the approval and permission which allows for the rehabilitation and operation of the pilot mill facility at SJG (“the Semarnat-SJG Mill Permit”, and, the “Semarnat Permit”). Under the terms of the Semarnat-SJG Mill Permit, DynaMexico will be responsible to maintain the SJG pilot mill facility, and including the adjacent tailings pond area, in compliance with the regulations described in la Norma Oficial Mexicana (“NOM-141-SEMARNAT-2003).

Mr. K.D. Diepholz, Chairman-CEO of DynaUSA, said: “I am pleased to receive notice of this significant, milestone accomplishment by DynaMexico. I would like to recognize Dr. Jose Vargas Lugo, President of Mexico Operations, for his commitment and diligence towards accomplishing the Semarnat-SJG Mill Permit. I would also like to recognize and give thanks for the support and assistance contributed to DynaMexico by the Office of Sinaloa State Governor Mario Lopez Valdez, including assistance provided by senior state government officials from Sinaloa, including: Lic. Roberto Cruz Castro-Secretario de Desarrollo Económico; Lic. F. Eloy Gonzalez Shinagawa-Subsecretario de Fomento Económico de La Secretaria de Desarrollo Económico; Lic. Marco Cesar Alejo-Director de Fomento Minero; and Lic. Víctor Duarte Ruiz–Asesor de la Secretaria de Fomento Económico. I would recognize also the professional work contributed by Biol. Ruben Rodriguez Navarro-Director General, Estudios Ambientales Para La Sustentabilidad, S.C., consulting engineer to DynaMexico.

Dr. Vargas, accompanied by his team of supporters for DynaMexico, met with Federal Semarnat Officials at the Semarnat Federal offices in Mexico City on June 1, 2013, and during the meeting submitted application documents on behalf of DynaMexico. I am pleased to realize the prompt response and permission issued by Semarnat to DynaMexico on such a fast track basis.

Accomplishing the Semarnat Permit by DynaMexico on this fast track is further confirmation of the strong support and assistance received by DynaMexico from senior officials within Sinaloa state government on a consistent basis over the past 10 years. I believe that the current regime of Sinaloa State Governor Lopez Valdez offers the prime support and opportunity for foreign investment in Sinaloa, Mexico. And, I sincerely appreciate the professional respect and support received in Sinaloa and in Mexico by DynaMexico.

Considering that DynaMexico now has the Semarnat-SJG Mill Permit in hand, and considering that Mineras de DynaResource S.A. de C.V. (“Mineras”) is the exclusive operating entity at San Jose de Gracia under operating agreement with DynaMexico, I expect Mineras to make immediate plans for the rehabilitation and subsequent operation of the pilot mill facility at SJG. The SJG pilot mill facility (a gravimetric-flotation circuit) is projected to process bulk samples to be mined from selected target areas of SJG. Operations at SJG will be managed by Mineras, and are projected to be similar to those conducted by DynaMexico during the 2003-2006 Period.” (See DynaUSA-DynaMexico Paragraph below.)

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.

These statements relate to future events or future performance and reflect the Company’s expectations regarding the future growth, results of operations, business prospects and opportunities of DynaResource. These forward-looking statements reflect the Company’s current internal projections, expectations or beliefs and are based on information currently available to DynaResource.

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. Forward-looking information is not a guarantee of future performance and actual results and future events could differ materially from those discussed in the forward-looking information.
