The 2012 DynaMexico Luna-CAM SJG 43-101 Technical Report, and as revised at December 31, 2012 and the 2012 DynaMexico-CAM SJG Mineral Resource Estimate included within the Technical Reports, are the current and only Technical Reports and Mineral Resource Estimate for SJG which have been approved by DynaMexico, the 100 % owner of San Jose de Gracia. I am pleased with the thoroughness and accuracy of the updated 2012 DynaMexico Luna-CAM Technical Report, and I am excited to report again the results of the 2012 DynaMexico-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 DynaMexico's commissioning and completing of a Preliminary Economic Assessment ("PEA") for SJG, and I look forward with excitement to the continuing development of the SJG project in the best interests of DynaMexico."

San Jose de Gracia ("SJG")

The San Jose de Gracia District, covering 69,121 hectares, is 100% owned by DynaResource de Mexico ("DynaMexico"). DynaResource, Inc. ("DynaUSA") currently holds 50% of the outstanding shares of DynaMexico and Goldgroup holds 50% of the outstanding shares of DynaMexico.

In excess of one million ounces gold was reportedly produced from the SJG District in the early 1900's, originating from high grade gold veins, including approximately 470,000 Oz. gold reportedly produced from the La Purisima area of SJG at an average gold grade of 66.7 g/t. In June 2010, the SJG Project was recognized by the State of Sinaloa as the most significant Gold Project in the State for the year 2010.

DynaUSA - DynaMexico

DynaUSA (the "Company") is a Resource Investment and Management Company based in Irving, Texas, with a current focus on the SJG Project in Mexico, targeting growth in the defining and production of predominately gold resources. The Company formed DynaMexico in March 2000 specifically for the purpose of acquiring and consolidating the SJG District; and it completed the consolidation of the entire SJG District to DynaMexico in 2003 (approx. 15 sq. km. at that time), * with the exception of the San Miguel Mining Concession (7 Hectares, which DynaMexico is endeavoring to accomplish the transfer of title to DynaMexico, under previously signed sale and purchase agreements). During the period 2003-2006, DynaMexico conducted Pilot Production operations at the San Pablo area of SJG, reporting production results of: 18,250 Oz. Gold produced; 42,000 tons mill feed; average feed grades of approximately 15-20 g/t Gold; and, average production costs of less than $175./Oz. In September 2006, the Company entered into an Earn In/Option Agreement with Goldgroup, which provided that Goldgroup contribute $18 M. USD in funding to DynaMexico for exploration/development expenditures at SJG, in exchange for 50% of the outstanding shares of DynaMexico.
