Dia Bras Exploration Inc. is pleased to announce that its board has approved a new exploration/development budget of $7 million primarily to drill the Promontorio, Santa Eduwiges and La India silver deposits in light of recent positive exploration results in these three areas.

Riverside Resources Inc. and its partner, Sierra Madre Developments are pleased to announce positive assay results including greater than 1 g/t gold in soils from a detailed soil sampling program designed to assess potential western extensions of the El Capitan oxide gold zone at the Penoles Project in Durango, Mexico.

The La Negra Mine has successfully completed its second consecutive mine expansion from 1,500 tonnes per day (tpd) to 2,000 tpd capacity on time and on budget for a cost of $4.5M. Production is anticipated to increase from 130,500 tons at 1500 tpd from Q1 2012 to 176,000 tons at 2,000 tpd for Q2 2012.

Goldgroup Mining Inc. is pleased to announce further assay results from the continuation of underground tunnel development at the Company’s 100%-owned Caballo Blanco gold project in Veracruz, Mexico. Both the main tunnel and a new crosscut tunnel to the west of the main tunnel continue to encounter mineralized, massive and brecciated massive silica. Assay results from the channel sampling in the main tunnel returned 49.40 metres of 1.13 g/t gold and 28.25 metres of 1.26 g/t gold from channel sampling in the crosscut tunnel. The average gold grades of the mineralized zones in the tunnel continue to correspond well with the grades of the drill holes completed in the area surrounding the tunnel. These results provide indirect confirmation for a robust resource model, serving to de-risk the Caballo Blanco project.
