Almaden Minerals Ltd. is pleased to announce further results from the on-going 4 drill exploration program on the Company’s 100% owned Tuligtic project, Mexico with holes TU-12-133, 138, 139, 141 through 144 and 146 through 150. Holes TU-12-138, 143, 144 and 146 were drilled into the Ixtaca North Zone a developing parallel zone to the Main Ixtaca Zone. Results from these holes continue to show that this zone, as presently interpreted, exists over a strike length of nearly 700 meters. Highlights from the current group of assays include the following intercepts (a more complete list of intercepts is shown in the table below):

Cotton & Western Mining, Inc. — The Qin Hai Bulk Cargo Vessel sailed out of the Pacific Ocean Port of Ensenada, Baja California, Mexico on June 13, 2012, with a full maximum load 43,829 WMT of Raw Crude Iron Ore sized 1-10mm under contract with Bao Steel. 45,000 WMT remains stockpiled at the port pending dispute resolution with the Mexican Authorities over time lapse in customs. The company began trucking on Oct 24, 2011 through Nov 11, 2011 for a shipping date of Dec 21, 2011; during the month of December, 2011, all iron ore export permits were canceled country wide, and new export regulations became effective overnight. The new iron ore export regulations not only required an iron ore export permit from the Secretary of Economy, but also included a Customs iron ore exporters listing; this entailed a series of Government audits, from the Tax Office, Mining Office, Environmental Agency and from Customs if the company had any prior exports of Iron Ore. Panamerican Minerals Ventures, S.A. de C.V., the Mexico Iron Mining Operator, begin the process of re-qualification to meet the stringent and rigorous new regulations. The Company received the new Secretary of Economy Export Permit in January 2012; however, the audits and other time consuming efforts for Customs listing resulted in the Company becoming one of only a few mining companies authorized to export iron ore from Mexico, on March 6, 2012.

Goldgroup Mining Inc. is pleased to announce final assay results from the completed underground tunnel development at the Company’s 100%-owned Caballo Blanco gold project in Veracruz, Mexico. Both the recently completed main tunnel and crosscut tunnel west of the main tunnel encountered mineralized, massive and brecciated massive silica. Assay results from the channel sampling in the main tunnel returned 24.2 metres of 1.09 g/t gold and the crosscut tunnel returned 19.35 metres of 1.48 g/t gold. The average gold grades of the mineralized zones in the tunnel correspond well with the grades of the drill holes completed in the area surrounding the tunnel, and demonstrates strong gold grade continuity through this section of the Caballo Blanco mineralized zone. These results provide confirmation of a robust resource model, further de-risking the Caballo Blanco project. A sufficient supply of mineralized material has been stockpiled from the underground tunnel development for all anticipated remaining metallurgical test work at Caballo Blanco.

Primero Mining Corp. is pleased to announce the discovery of a new high-grade vein in the West Block which has been named the Alexa vein. The discovery currently comprises five high-grade intercepts that include 16.0 grams per tonne (g/t) of gold (Au) and 508 g/t of silver (Ag) over 2.9 metres, 13.4 g/t of Au and 543 g/t of Ag over 2.9 metres and 7.4 g/t of Au and 188 g/t of Ag over 4.1 metres.

Paramount Gold and Silver has reported that it has validated the mineralization continuity along the Guazapares Megastructure, through the results obtained from four new near-surface holes drilled at its San Miguel Project, Mexico.

International Northair Mines Ltd. is pleased to announce that it has reached an agreement to purchase the surface rights to approximately 1,098 hectares adjoining the La Cigarra Project, located in the north central Mexico.

Riverside Resources Inc. reports that the option agreement whereby Mexigold Corp. could earn an interest in the Catrina, Pedernal and Escondida projects is being terminated and Riverside will retain 100% interest in the projects. Riverside is pleased to move ahead with the Durango Properties, while Mexigold has elected to pursue other business opportunities during these difficult market conditions. Two of the properties, Catrina and Pedernal, have been drilled with an aggregate $1.83 million in exploration funding from Mexigold, which builds upon the earlier exploration investment made by Kinross and Riverside.

Para la exploración y barrenamiento que realiza la empresa Minera Frisco SA de CV, en Tetela de Ocampo, no es necesario que cuente con el manifiesto de impacto ambiental, ya que la actividad se encuentra bajo la Norma Oficial Mexicana NOM-120-SEMARNAT-2011.

Paramount Gold and Silver Corp. reported today that results from four new shallow core holes on its 100%-owned San Miguel Project in Mexico confirm the continuity of mineralization along the 7.5 km. long Guazapares Megastructure. These holes were drilled into the 1.2 km untested gap separating the San Antonio and La Veronica deposits. (See maps below) The results demonstrate that San Miguel’s Guazapares is one of the longest continuously mineralized structures in the Sierra Madre Metallogenic Belt.

Soltoro Ltd. has completed in excess of 10,000 metres of this year’s planned 20,000 metre drill program at its El Rayo primary silver project in Jalisco, Mexico. Results from the latest round of drillinginclude high-grade silver intercepts of 1.2 metres of 706 g/t silver at the La Soledad West deposit and 4.5 metres of 378 g/t silver in a newly discovered zone east of the Matachines mine at the south end of the Las Bolas structure. Drilling continues in order to expand existing silver resources along extensions of known resource areas and at newly identified prospective exploration target areas.
