Keith Piggott, CEO of Goldgroup stated, "We are very pleased with these new assay results as they are consistent with the grades and intercepts of previously released results and indicate a consistent pattern of gold mineralization throughout San José de Gracia's high-grade multi-vein system."
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. Results from these latest holes and the prior 62 holes announced in news releases dated June 11, 2010, September 8, 2010, September 20, 2010 and December 7, 2010 represent new drilling completed since the calculation of the current mineral resource estimate and are intended to be used in the estimation of an updated mineral resource.
A complete summary of the assay results from drill holes SJG-10-189 to SJG-10-224 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 advancing a remaining US$4 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. Please refer to the NI 43-101 technical report on San José de Gracia dated March 22, 2010 which is available on SEDAR. 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. Mr. Sullivan is Goldgroup'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.
