McEwen Mining Inc. is pleased to announce exploration drill results from its 100% owned El Gallo Complex, in Sinaloa State, Mexico. Drilling has extended the known mineralized zones within the Phase 1 production area, where mine commissioning is underway (Fig. 1). The most impressive hole returned 1.1 gpt gold over 71.3 m, including 6.6 gpt gold over 4.9 m, which is believed to be the widest intersection of +1 gpt gold recorded at the property (Fig. 2 & 3).

Excellon Resources Inc. wishes to advise its stakeholders that the recent allegations against the Company by the Justice and Corporate Accountability Project, regarding the Company’s disclosure obligations are in all respects baseless and founded on false information.

MAG Silver Corp. is pleased to announce that exploration drill hole CM12-431 has intersected four distinct, closely spaced zones of massive sulphides ranging from 3.1 metres to 61.6 metres in thickness (See Diagram 1 and Table 1). These new discovery intercepts were drilled approximately 225 metres beneath the strongest mineralization previously drilled in the “Jose Manto-Bridge Zone” and show all of the hallmarks of the near-source part of the Carbonate Replacement Deposit system that MAG has been systematically seeking at Cinco de Mayo. The mineralization in the upper intercept of Hole CM12-431 is likely connected to the 4 kilometre long Bridge Zone-Jose Manto where high grade mineralization of lead, zinc and silver has previously been drilled.

El Tigre Silver Corp. is pleased to provide a drill hole assay report from the most recent four holes from the ongoing Gold Hill core drilling program at its 100% owned El Tigre silver project in Sonora, Mexico.

Riverside Resources Inc. and its partner, Sierra Madre Developments are pleased to announce results of two step-out holes (CDDH 12-12 and CDDH 12-13) drilled approximately 50 meters to the east of the area referred to as the Main Zone of the El Capitan Target (see press release dated October 24, 2011). Results of CDDH-12 and CDDH 12-13 include some of the widest and best grade intervals encountered to date within El Capitan. CDDH 12-13 is a vertical hole drilled from a station approximately 50 meters east of CDDH 11-07 and CDDH 12-11 and intersected mineralization from surface to a depth of 130.20 meters. The entire hole returned an average grade of 0.555 g/t gold, including a 61.15 meter section that averaged 0.919 g/t gold. The hole was stopped in mineralization, which is open at depth below this hole. CDDH 12-12 was drilled at an inclination of 60 degrees from the same pad and intersected mineralization from surface to a depth of 161.8 meters. The entire drill hole averaged 0.329 g/t gold and included a 29.31 meter interval that averaged 0.737 g/t gold. The true thickness of these mineralized intervals is estimated to be approximately 90% of the reported core lengths. The eastern part of the Main Zone has returned the widest mineralized intervals encountered so far at El Capitan and appears to be open for expansion down dip of CDDH 12-13. Additional drilling in this area is planned upon completion of the current program.

Lone Star Gold, Inc. is pleased to provide an update on its Tailings Project operations and expansion near the city of Hidalgo Del Parral in the state of Chihuahua, Mexico.
