These assays are consistent with those of the A4 vein found and mined in the lower levels of the active portions of the Santa Juana mine, 1,200 meters (3,937 feet) above these intercepts but over a wider true width of 6 meters compared to the 0.5 to 2.0 meters normally encountered in the mine workings. The zone is situated at the contact between a green garnet skarn unit and a quartzo-monzonitic intrusive, both of which are mineralized with small quantities of chalcopyrite.
As the hole continued, it cut more intrusive and green skarn and a second less extensive mineralized zone of a nature similar to the first one. It was sampled and assays are pending.
From a geological point of view, the two most important aspects of the geological sequence found is the nature of the intrusive rock, a quartzo-monzonite instead of the diorite found in the active mine, and disseminations of chalcopyrite instead of sphalerite in the green garnet skarn. In the geological model, developed by the geologists of various companies who worked in the area which is a variation of the general Sierra Madre model, the mineralization is associated with acid stocks and dykes that intruded the sedimentary limestones. These intrusive are aligned in a NE-SW trend for 15 kilometers stretching from the Santa Maria mine to the San Diego property. At both extremities of the trend, the San Diego property and the Santa Maria mine, significant Zn-Pb-Ag mineralization was mined, over average widths of 3.5 meters at the Santa Maria mine, at the contact between aslaskite/quartzo-monzonite dykes and skarn or limestone. In the NE section of the center, the mineralization at the Reina del Cobre mine has less zinc and lead but more silver and copper, again associated with the contact between acid intrusive and the host rocks, with average widths of 4 meters. In the SW section of the center, the mineralization in the upper sections Santa Juana mine is predominantly thin epithermal veins cutting through all the local host rocks, limestone, skarn and dioritic intrusive. The information from this new hole, SJ-18-21B, seems to indicate that the mineralization is evolving to a type similar to that found at Reyna del Cobre with thicker veins, current cuts of 4 and 6 meters of true widths, quartzo-monzonitic or granitic intrusive and pervasive chalcopyrite (copper sulfide) disseminated in the veins and the skarn. The main difference is that the mineralization at Santa Juana includes gold.
On June 24th, the Company announced that it had entered into an agreement to merge with Golden Minerals Company ("Golden Minerals") to create an exciting new junior precious metals mining company. The details of the proposed merger have been documented in detail and have been sent out to the respective shareholders of each company. Securityholder votes will be registered at a special meeting of shareholders for both companies to occur on August 30, 2011.
Cautionary Statements
Readers are cautioned that until a prefeasibility study is completed, there are no assurances these latest mineralized zones will be economically viable.
All lengths are core lengths and all widths are true widths. Samples were assayed at the ERSA laboratory in Torreon, Coahuila, Mexico which is currently in the process of being certified. Mr. Michel Roy, P. Geo., a "qualified person" within the meaning of NI 43-101, prepared the technical information disclosed in this news release.

Although the Company believes that such statements are reasonable, it can give no assurance that such expectations will prove to be correct. Forward-looking statements are typically identified by words such as: believe, expect, anticipate, intend, estimate, postulate and similar expressions, or are those, which, by their nature, refer to future events. The Company cautions investors that any forward-looking statements by the Company are not guarantees of future results or performance, and that actual results may differ materially from those in forward looking statements as a result of various factors, including, but not limited to, variations in the nature, quality and quantity of any mineral deposits that may be located, significant downward variations in the market price of any minerals produced, the Company's inability to obtain any necessary permits, consents or authorizations required for their activities, to produce minerals from their properties successfully or profitably, to continue their projected growth, to raise the necessary capital or to be fully able to implement their business strategies.
