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 Mineral 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 Qualified Person ("QP") calculating the resource estimate. 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 of recent production by DynaMexico from San Pablo of some 42,000 tonnes plant feed at an average 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 for SJG 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 of ore processed 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 gram 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.
Mr. Luna initially visited the San Jose de Gracia Project in November 2010, and conducted site inspections at SJG 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 José 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 José de Gracia's core logging and storage facilities.
K.D. Diepholz, Chairman and CEO of DynaResource, Inc., and President of DynaMexico stated:
"The 2012 DynaMexico Luna-CAM SJG 43-101 Technical Reports and the 2012 DynaMexico-CAM SJG Mineral Resource Estimate were commissioned by DynaMexico in the best interests of DynaMexico and SJG in order to correct a previous technical report and resource estimate for SJG which were released without authorization by Goldgroup Mining Inc. on November 23, 2011, and filed by Goldgroup with SEDAR on January 3, 2012; and which technical report and resource estimate were released and filed by Goldgroup without approval from DynaMexico. Goldgroup is a shareholder of DynaMexico and as such has no authority to independently commission or release a technical report or resource estimate for SJG.
