Lincoln Mining Corporation reports that in December 2011 it completed 5,091.3 m of core drilling in 20 angle holes at its 100% owned La Bufa property in Chihuahua State, Mexico. The property is located in the Guadalupe y Calvo mining district which encompasses a large, northeast-trending epithermal gold-silver system. Gold-silver mineralization is hosted in quartz-breccia veins and stockworks that are localized in a complex zone of high-angle structures. Core drilling focused on two target areas which were defined by geologic mapping, surface sampling, and geophysics. Drilling commenced in mid July 2011 and was completed in early December. Core recovery was excellent. All assays have been received. Drill hole intercepts reported here are apparent and do not represent true thicknesses.

Aurcana Corporation is pleased to report silver production for Q1 2012 of 287,486 ounces compared to 240,275 in Q1 2011 , the largest quarter for silver production in Aurcana’s history. Silver production for the first quarter of 2012 increased 19.6% compared to Q1, 2011. Silver Equivalent increased 29.3% to 492,864 for Q1 2012, compared to 381,146 in Q1 2011.

Kootenay Silver Inc. is pleased to announce results from an additional 10 holes from its current 25,000 meter drill program on its Promontorio Silver Project in Sonora, Mexico. The Company reports the two-phase 35,000 meter in-fill drill and resource definition program, comprised of 25,000 meters of core drilling and 10,000 meters of RC drilling is now complete. Work on an independent NI 43-101 resource update to incorporate results from drilling is underway.

Westridge Resources Inc. announces that drilling at its Charay Project in Mexico has extended high grades in the El Padre Vein to depths of approximately 150 meters down dip (2.4m at 10.15 gpt Au, including 1.4m at 15.25 gpt Au and 127 gpt Ag). Drilling has also intersected additional high grade veins not previously known (1.0m at 20.6 gpt Au). Surface sampling has identified high grade gold values (up to 12.5 gpt Au) in new additional epithermal veins and extensions of the El Padre system.

Parlane Resource Corp. announced that it has given notice terminating its option agreement to earn a 100% interest in the Mercedes Property located in Hermosillo in the state of Sonora, Mexico. (See press release dated February 22, 2011.)

Arian Silver Corporation, a silver exploration, development and production company with a focus on projects in the silver belt of Mexico, today announced the release of a Mineral Resource Report dated 23 April 2012 and entitled “Arian Silver Corporation, Resource Estimate 43-101 Technical Report, San José Project, Zacatecas, Mexico” prepared by CSA Global (UK) Limited relating to the updated mineral resource estimates contained in Arian’s press release dated 12 March 2012 entitled “Arian Silver Increases Contained Silver at San José by 32% to More Than 117 Million Ounces in Updated Mineral Resource Estimate”.

International Northair Mines Ltd. is pleased to announce that an additional core drill rig is on site to expedite the drill program underway at its La Cigarra silver project, located in north central Mexico.

Garibaldi Resources Corp. is pleased to announce results of exploration drilling on its 100% owned Tonichi Project. The ongoing drill program was designed to evaluate the potential of the Locust Target that was defined by surface soil and rock chip sample anomalies (see press releases of June 2, 2010 and October 9, 2009). To date, four diamond drill holes have been completed using the Company’s drill, for a total of 905.8 meters drilled. A fifth hole is in progress. Assay results have been received for the first four holes. Hole LCT-11-03 has encountered gold mineralization of 1.25 g/t over 13.95 meters, and hole LCT-12-04 encountered 6.4 meters of 1.12 g/t Au. The table below includes assay results for the drill holes received to date.

Canasil Resources Inc. announces that Pan American Silver Corp. has elected to terminate the option agreement on Canasil’s Carina silver-gold project in Durango State, Mexico. At the time of entering into the agreement, Pan American was required to assign the agreement to the La Preciosa joint venture between Pan American and Orko Silver Corp. As previously announced by Orko on April 5, 2012, Pan American has relinquished its right to earn a 55% interest in the La Preciosa project and the Carina option will not be continued by the La Preciosa joint venture company. As a result Canasil now retains 100% interest in the Carina project.

Impact Silver Corp. is pleased to announce additional high grade silver values and wide zones of mineralization from the second phase drill program on the Oscar Project. Highlights include 1,875 g/t Silver across 1.00 meters and 115 g/t Silver across 23.39 meters. Oscar is located only 2.5 kilometers east of IMPACT’S operating 500-tonne-per-day Guadalupe processing plant in the 423 square kilometer Royal Mines of Zacualpan District of central Mexico. These results are in addition to previously announced results from the Oscar Project, which included multiple intersections over 1,000 g/t Silver (see IMPACT News Releases dated October 20 and 26, 2011).
