(Due to rounding the numbers in the above may not check exactly. Tonnes and contained metal are reported to nearest tonne, troy ounce or kilogram for comparative purposes only and do not imply this degree of precision or accuracy. This is an estimate of in situ resources only and there is no assurance that any part of these resources can be converted to reserves)

Data used in the CAM SJG Mineral Resource Estimate was provided and reviewed by Mr. Ramon Luna of Servicios y Proyectos Mineros, a Qualified Person as defined under NI 43-101. Resources were estimated by CAM, Mr. Sandefur QP, within wireframes constructed by technical personnel of Minop SA de CV ("Minop"), a subsidiary of Goldgroup Mining Inc. ("Goldgroup"). Minop was contracted by Mineras de DynaResource SA de CV. ("Mineras"), a 100% subsidiary of DynaUSA and the operating entity at SJG under agreement with DynaMexico. DynaUSA holds 50% of the outstanding shares of DynaMexico and Goldgroup holds 50% of the outstanding shares of DynaMexico.

An NI 43-101 compliant technical report will be filed on SEDAR (www.sedar.com) within 45 days of this news release.

Parameters Used to Estimate the Mineral Resource

The data base for the San Jose de Garcia Project consists of 372 drill holes of which 361 were diamond drill holes and the remaining 11, drilled in 1992, were reverse circulation holes, with a total drilling of 75,878 meters. The CAM SJG Mineral Resource Estimate concentrates on four mineralized vein systems at SJG: Tres Amigos, San Pablo, La Union, and La Purisima. Of the 372 drill holes, 368 were drilled to test these four vein systems and the remaining four holes tested the Argillic Zone. Technical personnel of Minop built three dimensional solids to constrain estimation to the interpreted veins in each swarm. The 172 holes most recently drilled, 2009-2011, were allocated as follows: Tres Amigos (64 holes), San Pablo (49 holes), La Union (24 holes), La Purisima (32 holes) and the Argillic Zone (3 holes).

Servicios y Proyectos Mineros performed a database review and considers that a reasonable level of verification has been completed, and that no material issues have been left unidentified from the drilling programs undertaken.

A total of 5,540 pieces of core were measured for specific gravity using the weight in air vs. weight in water method. This represents an additional 3,897 measurements taken in the 2009-11 drill seasons with density measurements taken from all mineral zones. Dried samples were coated with paraffin wax before being measured. The results tabulated have been sorted by lithology and mineralized veins. The average specific gravity of 5,051 wall rock samples is 2.59 while the average specific gravity for 489 samples of vein material is 2.68. CAM and Servicios y Proyectos Mineros have reviewed the procedures and results, and opine that the results are suitable for use in mineral resource estimation.

Explanation of Resource Estimation

Resource estimation was done in MineSight and MicroModel computer systems with only those composites that were inside the wireframe used in the estimate. Estimation was done using kriging with the omni-directional variogram derived from all the data in each area for gold using the relative variogram derived from the log variogram. High grades were restricted by capping the assays at a breakpoint based on the cumulative frequency curves. Estimation was done using search radii of 100 x 100 x 50 m oriented subparallel to the general strike and dip of the vein system in each area. A sector search, corresponding to the faces of the search box with a maximum of two points per sector was used in estimation. A density of 2.68 based on within vein density samples was used in the resource estimate. Within each of the four areas there are approximately 20 to 40 veins in the vein swarm. Resources were estimated by kriging using data from all veins in the swarm. In general, gold accounts for at least 80% of the value of contained metal at the project, so the variograms for gold were used in estimation of the four other metals. Resources at Tres Amigos and San Pablo were classified as Indicated as follows:

1)

they were within a vein within the swarm which contained at least 7 drill holes;

2)

they are within 25 m of the nearest sample point; and,

3)

they were estimated by at least three drill holes.

All other resources were classified as Inferred. Because there are no precise quantitative definitions of measured, indicated and inferred, resource classification is subjective and depends on the experience and judgment of the QP doing the resource. CAM, Mr. Sandefur QP, allowed indicated material at Tres Amigos and San Pablo because of (1) the similarity of the variograms, and (2) the fact that there was recent production by DynaMexico from San Pablo of some 42,000 tonnes at a feed grade of approximately 15 g/t. Three of the individual veins at La Purisima satisfied criterion (1) above but Mr. Sandefur elected not to include this material in indicated because of the shorter first range at La Purisima. This mineral resource estimate does not include any ore loss or dilution outside wireframes, and as currently defined, is probably most appropriate for a highly selective, small equipment underground operation.

The veins at San Jose de Gracia have been historically mined for many years and historic mined volumes are not available. The one exception is the approximate 42,000 tonnes mined by DynaMexico during its pilot production activities in 2003-2006. The resource table is not adjusted for any historic mining. To validate that historic mining had not significantly reduced the resource, CAM reviewed the database for all assays greater than 1 g per ton gold that were next to missing values at the bottom of drill holes. Only four assays satisfying this criterion were found, and on the basis of this review, CAM does not believe that significant mining has occurred within the volumes defined by the wireframes.

Data Verification

Mr. Luna visited the San Jose de Gracia Project in November 2010, and conducted site inspections in November 2011 and January 2012. Mr. Sandefur conducted a site inspection of the SJG Project in January 2012. While at the Property in November 2011, Mr. Luna inspected the areas of Tres Amigos, La Prieta, Gossan Cap, San Pablo, La Union, and La Purisima, and historic mining sites. In January 2012, Mr. Sandefur and Mr. Luna inspected the areas of Tres Amigos, San Pablo, La Union, and La Purisima. Pictures of the areas were taken. Many of the drill pads for the drilling programs of 2007 to 2011 were clearly located and identified. Mr. Luna also inspected San Jose de Gracia's core logging and storage facilities, the geology offices, the meteorological station, the plant nursery, and the mill. Mr. Sandefur also inspected San Jose de Gracia's core logging and storage facilities, the plant nursery and the geology offices.

A total of 10 rock samples were collected by Mr. Luna in November 2011, including 1 rock sample of quartered core from drill hole number SJG DDH 10-179 at Tres Amigos (from 176.17 to 177.5 meters), 2 rock samples of quartered core from drill hole SJG DDH 08-051 at San Pablo (from 183.6 to 184.6 meters) and drill hole number SJG DDH 10-203 at San Pablo (from 36.05 to 36.75 meters), plus 2 ore dump samples from underground workings at the same two drill holes, 0 samples from quartered core from the drill holes from La Prieta, 3 rock samples from quartered core from drill hole number SJG DDH 10-223 at La Union (from 62.25 to 63.90 meters, from 63.9 to 65.40 meters, and from 65.40 to 66.15 meters) and 0 rock samples from quartered core from the drill holes at La Purisima. All of these rock samples were hand delivered to ALS Chemex Labs of Hermosillo, Mexico for analysis. Mr. Luna suggests that the 10 check samples described support the fact that gold mineralization can be verified from the 5 "point" locations, in five areas namely, Tres Amigos, La Prieta, San Pablo, La Union and La Purisima.

K.D. Diepholz, Chairman and CEO of DynaResource, Inc., and President of DynaMexico stated:

"The CAM SJG Mineral Resource Estimate was commissioned in the best interests of DynaMexico in order to correct a previous resource estimate for SJG which was released prematurely by Goldgroup Mining Inc. on November 23, 2011, and released without approval from DynaMexico. Goldgroup is only a shareholder of DynaMexico and as such has no authority to independently commission or release a resource estimate for SJG. The major differences between the premature, non-approved resource estimate released by Goldgroup and the CAM SJG Mineral Resource Estimate as reported here in this news release are shown in the table below:

The CAM SJG Mineral Resource Estimate is the current and only resource estimate for SJG which has been approved by DynaMexico, the 100 % owner of San Jose de Gracia. I am pleased with the results of the CAM SJG Mineral Resource Estimate as it confirms the first major milestone for defined resources at SJG, and it confirms the confidence in the resources defined by recent drilling at Tres Amigos and San Pablo.

I look forward to receiving and releasing the NI 43-101 technical report for SJG, Mr. Sandefur and Mr. Luna – QP's, and subsequently I look forward to DynaMexico's commissioning and completing of a Preliminary Economic Assessment ("PEA") for SJG. Further, I look forward with excitement to the continuing development of the SJG project in the best interests of DynaMexico."

IMPORTANT CAUTIONARY NOTE REGARDING CANADIAN DISCLOSURE STANDARDS

The Company is or about to be 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.
