December 9, 2010 – Vancouver, BC: Riverside Resources Inc. (“Riverside” or the “Company”) (TSX-V: RRI) is pleased to report it has successfully built a portfolio of five drill ready gold-silver projects located in the rich producing Mesa Central region of Mexico. The Durango Gold Properties portfolio has been strategically developed to give Riverside a strong position in one of the most prolific mineral belts in Mexico. These projects add substantial value to Riverside’s property portfolio and were developed at a relatively low cost through a completed Exploration Alliance with Kinross Gold Corporation.

Riverside’s most recent exploration work identified a high potential anomalous target zone at the 100% Riverside owned Escondida Gold Project, in Zacatecas, Mexico. The Company’s completed exploration program on the 160 km² property included detailed mapping, sampling, structural analysis and geophysics. Two east-west striking mineralized trends were identified at Escondida within a 2.1 km by 1.3 km zone defined as the primary drill target area. These mineralized structures were identified through a geophysical IP survey with the target area remaining wide open in multiple directions. The outcropping, cross cutting mineralized structures and projection undercover show many similarities to the nearby Valenciana and San Jose de Reyes mining districts. Several potential drill targets have been delineated for immediate follow up. The table below provides a brief summary of Riverside’s other Durango Gold Properties.

Additional Durango Gold Properties

“The Durango portfolio is the culmination of two and a half years of generative exploration and targeting through the Riverside – Kinross Exploration Alliance, and includes the top projects out of more than 220 anomalous areas that were evaluated.Riverside will consider bundling this portfolio into a major asset deal that could provide upside exposure through a well-funded and accelerated drilling campaign.” stated John-Mark Staude, President and CEO of Riverside Resources Inc.
