Bowmore Exploration Ltd. would like to inform its shareholders that the drill campaign at the “Chivas property” is well underway and that three holes have now been completed. The initial drill program experienced some delays due to technical difficulties encountered by the previous drilling contractor. Therefore a second drill company “Major Drilling Group International Inc.” was contracted to complete the campaign. Samples of the first holes have been sent to ALS Chemex lab in Hermosillo, Mexico and results should be available in the following weeks.

Jacinto Martinez is the labor secretary of Section 65 of the Mineros, Mexico’s union for miners and one of the oldest unions in the country. His union has been on strike for five years at the huge Cananea mine, one of the longest strikes in the history of North America. Critical support for this strike has come from the United Steelworkers, and both unions have announced their desire to merge to form a single organization.

El Tigre Silver Corp. is pleased to provide a progress report along with the first assays from the ongoing Gold Hill core drilling program at its 100% owned El Tigre silver project in Sonora, Mexico.

Cayden Resources Inc. is pleased to announce that it has now received over 1,200 assays from its La Magnetita and La Joya soil program (see website for map) which indicate an extensive gold anomalous area that is up to 5 km in an EW direction by 2 km in a NS direction. the soil anomaly strongly suggests that the La Magnetita and La Joya targets are part of the same very large hydrothermal system. Cayden is currently planning a drill program in the western portion of the La Magnetita anomaly where the most extensive surface work has been completed. There are presently over 2,000 meters of trench samples in the assay lab and the Company is creating a detailed geologic map from outcrop and trench exposures that it will use to refine drill targets. The Company anticipates drilling a minimum of 6,000 meters by reverse circulation once all the trench assays have been received.

Arco Resources Corp. is pleased to announce that Micon International Ltd. has completed an independent technical report under National Instrument 43-101 that includes a mineral resource estimate on the Company’s 100%-owned Taviche property located near Oaxaca City, Mexico. The Inferred Mineral Resource estimate is 160,000 tonnes grading 197.8 g/t Silver (Ag) and 0.85 g/t Gold (Au), at a 100 g/t Silver Equivalent (AgEq) cut-off. This equates to 1,017,000 ounces of silver and 4,400 ounces of gold at a 100 g/t AgEq cut-off. This is the first mineral resource estimate ever on the Taviche Property. The report has now been filed on SEDAR and recommends a two-phase property-wide exploration program with a budget of $556,000.

Goldgroup Mining Inc. announces that the technical report on the updated mineral resource estimate on the Cerro Colorado gold mine titled “NI 43-101 Technical Report, Cerro Colorado Gold Mine, Sonora, Mexico” effective February 29, 2012 and dated May 14, 2012, has been filed on the Company’s website and on SEDAR in compliance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects requirements.

Westminster Resources Ltd. has recently completed an extensive program of geological mapping, prospecting and soil and rock geochemical sampling at the Cumbral-San Bartolo property located near Obregon, Sonora, Mexico. The original Cumbral exploration program conducted by Westminster in 2011 included an airborne VTEM/MAG geophysical survey with grid-controlled ground follow-up 2D-IP and MAG geophysical surveys over selective anomalies. These surveys identified a series of coincident IP chargeability-resistivity and magnetic patterns which were further defined with anomalous copper and silver trends from the 2012 soil geochemical sampling program.
