Riverside Resources Inc. has commenced an initial 2,000 m diamond drill program at the Cuarentas Gold Project with exploration partner Hochschild Mining Plc. The initial drilling campaign will consist of 10 holes over the historical Santa Rosalia Mine and Santa Rosalia Sur gold vein target areas. These targets are located 1 km apart and form part of a large epithermal vein system. Other notable epithermal vein systems in the district include Premier Gold Mines, Mercedes Mine, immediately to the west and Silvercrest Metals, Las Chispas Mine, to the southeast. Riverside's program will test the strike and depth continuity of the gold-bearing veins from the historical mine workings. Riverside's recent exploration work defined the Santa Rosalia target as part of a bigger system with a total of 5 parallel geophysical resistivity anomalies, which are interpretated as possible hidden quartz vein zones along the northern part of the property. To the best of Riverside's knowledge, the Santa Rosalia Mine area has never been drilled. The company has contracted Globexplore out of Hermosillo, Sonora to carry out the drill program. As part of the drilling program Riverside will be using oriented core technology that should add significant understanding on the downhole vein and fault orientations allowing for more detailed interpretations and targeting for subsequent drilling campaigns. The current drill program will form part of Hochschild's USD 700,000 minimum exploration commitment in year one.
