Riverside Resources Inc. is pleased to announce that partner-funded drilling has now commenced at the Company’s 100-percent-owned Penoles Project in Durango, Mexico. Riverside’s partner, Sierra Madre Developments Inc., is starting a minimum 1,500-meter drill program and is planning to test various parts of the high-grade Jesus Maria silver-gold vein system. The proposed diamond drill program will initially test beneath and adjacent to surface-sampled trench areas and along the structural trend of the vein system, and targets shallow intercepts along strike from high-grade Ag-Pb-Zn historic mine workings. This drilling is on less than 1 square kilometer of the greater than 300 km2 land package, which has more than 10 additional target areas controlled by Riverside in the historic Penoles District in northern Durango state, Mexico.
