2010 News Releases

Vancouver, British Columbia (September 20, 2010) - Goldgroup Mining Inc. ("Goldgroup" or the "Company"), in coordination with DynaResource, Inc. ("DynaUSA"--"DYNR-OTCBB"), is pleased to announce that drilling from the final 32 holes of the latest 15,600 meter 62 hole diamond drilling program at the San José de Gracia project in Sinaloa, Mexico ("San José de Gracia") has encountered significant mineralization yielding 105.51 g/t Au over 1.72 metres plus many intercepts above the 2.0 g/t Au cut-off grade including 19.80 g/t Au over 5.27 metres. Significant assay results from the remaining 32 holes in the program (SJG-10-157 to SJG-10-188), drilled in the Tres Amigos, La Union, Purisima and La Prieta veins, are presented in the tables below:

Keith Piggott, CEO of Goldgroup stated, "We are very encouraged by these assay results as they are indicative of the overall success of this recent drilling program and point to the Tres Amigos zone as a very promising area. We look forward to the commencement of a new drilling program at San José de Gracia in the very near future".

The holes presented above intersected mineralization in excess of the 2.0 g/t Au cut-off grade used in estimating the inferred mineral resource presented in the San José de Gracia NI 43-101 Technical Report dated March 22, 2010. Prior to this round of drilling, the Tres Amigos vein was estimated to contain 80,000 ounces of gold and 177,000 ounces of silver, hosted in 600,000 tonnes grading 4.13 g/t Au and 9.19 g/t Ag, forming part of a larger overall estimated mineral resource at San José de Gracia. Results from these latest 32 holes and the prior 30 holes announced in the news releases of June 11, 2010 and September 8, 2010 represent the results of new drilling completed since the calculation of the current mineral resource estimate and will be used in the estimation of an updated mineral resource expected to be completed in Q4, 2010. The next phase of drilling is expected to commence after the end of the rainy season in early Q4.

A complete summary of the assay results from drill holes SJG-10-127 to SJG-10-188 and a map of the San José de Gracia property detailing the relative locations of the drill holes used in estimating the current NI 43-101 mineral resource, this latest drill program and future proposed drilling, will be posted on the Company's website under "Projects -- San José de Gracia" at www.goldgroupmining.com.

The San José de Gracia District, covering 99,500 hectares, is 100%-owned by DynaResource de Mexico S.A. de C.V ("DynaMexico"). Goldgroup currently owns 25% of DynaMexico after completing the initial stages of its earn-in and has the right to earn an additional 25% (total of 50%) by expending US$5.5 million by March 15, 2011. The recent drilling expenditures were incurred in connection with the earn-in of the additional 25% of DynaMexico. The remaining interest in DynaMexico is owned by DynaUSA. San José de Gracia is a high-grade advanced exploration project hosting a NI 43-101 compliant mineral resource estimate contained in four separate veins: Tres Amigos, San Pablo, La Union area and the La Purisima trend. Historically, in excess of one million ounces of gold has been produced from the property from high-grade veins grading between 30.0 g/t Au to 60.0 g/t Au. Goldgroup and DynaUSA are targeting a mineral resource estimate capable of sustaining annual production of 100,000 ounces of gold from San José de Gracia.

Assaying and Qualified Person

After project geologists logged and marked the core, technicians cut the individual lengths with a diamond saw, then tagged the bags and secured them with security clips. The samples were then trucked to Hermosillo, Mexico where Inspectorate America Corp. ("Inspectorate") crushed each sample to -150 mesh. The rejects remained with Inspectorate while the pulps were air couriered to Inspectorate's Richmond, BC, Canada facility and analyzed for gold by fire assay with Atomic Absorption ("AA") finish. Samples over 1.0 grams per tonne gold were re-run using fire assay with gravity finish. In addition, a 30 element Inductively Coupled Plasma ("ICP") analysis (aqua regia digest) was conducted on all samples. A QA/QC program was implemented as part of the sampling procedure for the drill program. One standard, one blank or one duplicate was inserted per group of 20 samples sent the laboratory. These standards were purchased commercially from Rocklabs Ltd. of Auckland, New Zealand. The San José de Gracia drill program is under the direct supervision of Kevin Sullivan, B.Sc., MAusIMM, contracted by Mineras de DynaResource S.A. de C.V., the operating entity at San José de Gracia, and the Company's Vice President, Exploration and a qualified person, as defined by NI 43-101. Mr. Sullivan has reviewed the technical information contained in this news release and reviewed the release.
