February 7, 2011 – Vancouver, BC: Riverside Resources Inc. ("Riverside" or the "Company") (TSX-V: RRI) is pleased to report that its prospect generation business model is growing with the recently IPO listed Guerrero Exploration Inc (TSX-V: GEX) now beginning work on Riverside’s Cerro Azul Gold-Copper Project in Guerrero, Mexico. Guerrero Exploration Inc. hopes to commence drilling at Cerro Azul upon the successful completion of an initial $200,000 work program with Riverside acting as the operator. The Cerro Azul program will continue the generative exploration work already completed by Riverside, which identified multiple high grade copper-gold zones. These zones will now be tested further through prospect scale geological mapping, hand trenching, ground geophysics, and rock chip and soil sampling.

This joint-venture program is another positive step for Riverside as the Company continues to advance its portfolio with a shared-risk business strategy that exposes shareholders to upside and discovery, while not adversely draining its financial resources. During 2011 the Company expects to see a flow of new technical programs conducted on Riverside projects and new joint venture deals.

Agreement Details:

Guerrero Exploration Inc may earn a 60% interest in the property by incurring $300,000 in exploration expenditures, paying Riverside $90,000 in cash and issuing the Company a total of 1,600,000 shares within 24 months of signing the option agreement.

Previously released property details highlighted a mapping and sampling program that defined more than seven target areas including several epithermal gold targets and at least two porphyry copper-type target zones (Press Release March 4, 2009). Riverside’s earlier work outlined various high grade copper targets, particularly in the southern region of the property which will be a focus for further exploration work at the Cerro Azul Project.
