Highlights: — Three drill hole assays received to date; two drill holes (CO-12-60 & CO-12-62)were drilled along strike and one drill hole (CO-12-61) was a confirmation drill hole — Drill hole CO-12-60 intersected high gold grades of 5.89 g/t gold over 3.5 m including 21.9 g/t Au over 0.50m in oxides — Drill hole CO-12-62 intersected wider gold zone grading 1.39 g/t gold over 10.0 m including 3.14 g/t Au over 1.0 m in oxides — Drill hole CO-12-61 confirmed historic drilled mineralized zone — Four Drill holes were drilled into Low-grade gold high sulphidation “lithocap” sitting atop an igneous intrusion-driven hydrothermal system identified by the exploration team this year

Highvista Gold Inc. is pleased to report that it has identified a new large gold, silver and copper target at its 100% owned Canasta Dorada Gold Project, located within the Sonoran Gold Belt, in Sonora State, Mexico.

Mining company, Cayden Resources declared that it has received the latest drilling results from the Las Calles target at the Morelos Sur Gold property in Mexico.

Riverside Resources and Sierra Madre Developments have obtained assay results of a comprehensive soil sampling program that was specifically designed to test the possible west expansions of the oxide gold mineralization, which was identified during the phase I drill program conducted at the El Capitan target in Penoles project.

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.

Arco Resources Corp. announces that based on the recommendation of the board of directors of Argentum Silver Corp., the optionee of Arco’s Lachiguiri, Silacayoapan and Nino Perdido properties located in Oaxaca, Mexico, Arco filed with the General Direction of Mines in Mexico to reduce the size of the Silacayoapan claim from 20,788 hectares to 3,475 hectares. Further, Arco’s land team determined that it will not renew the claims comprising the Nino Perdido property after discussions regarding Argentum’s decision to drop the claims from the option agreement between Arco and Argentum.
