Copper at the Cerro Azul Project in Guerrero, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 26, 2011) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI)(PINK SHEETS:RVSDF)(FRANKFURT:R99) is pleased to announce that rock chip and soil samples returning copper values as high as 10% Cu and 1.8% Cu respectively were identified within a 5.3 by 0.8 km anomalous target zone at the Cerro Azul Project in Guerrero, Mexico. The high-grade copper results were found primarily within the southern portion of the Cerro Azul Project, which includes the Loma Coyote, La Minillas and Las Trojas target areas. Another target area for drill testing, Coacoyul, was identified in the northern part of the 260 km^2 property during this first phase of the 2011 work program at Cerro Azul. Riverside's technical team has collected more than 200 rock samples and 1850 soil samples thus far. Copper values for the rock sampling ranged from <5ppm Cu to >100,000ppm Cu (10%), while the soil sampling program reported results that ranged from <5ppm Cu to >18,000ppm Cu (1.8%). Riverside and Guerrero Exploration Inc. continue to jointly advance the Project towards drill testing.
Detailed maps and figures that highlight multi-element geochemistry results and drill target areas have been posted on the Riverside website. These maps show scale of individual targets and the trend of copper mineralization that appears to be spatially related to aeromagnetic anomalies.
"The recently completed work at the large Cerro Azul Project has better defined drill target areas that each show individual potential, and collectively has started to outline an intriguing trend of metallic mineralization," said John-Mark Staude, President and CEO of Riverside Resources.
Further Property and Exploration Program Details
The 260 km^2 copper-gold Cerro Azul Project is located in the Guerrero Terrane of the highly productive Southern Mexican Gold Belt. The 2011 work program at Cerro Azul has better defined target zones that Riverside previously identified through initial reconnaissance exploration. The first phase exploration program found the Loma Coyote area to show alteration zoning and soil geochemistry that could be interpreted as a potential porphyry related copper-gold type target. The aeromagnetic highs coincident with andesitic porphyry and volcanic rocks could be the upper reaches of a shallowly covered possible porphyry system which will be further prospected during IP and drill testing in the coming months.
Assaying and Qualified Person:
The scientific and technical data contained in this news release were prepared under the supervision of Locke Goldsmith, P. Eng., P. Geo., an independent qualified person to Riverside Resources, who is responsible for ensuring that the geologic information provided in this news release is accurate and acts as a "qualified person" under National Instrument 43-101 Standards of Disclosure for Mineral Projects.
Samples were taken to Hermosillo, Mexico where ALS Laboratory Group's mineral division ALS Chemex crushed and pulverized each sample. The rejects remained with ALS Chemex while the pulps were transported to ALS Chemex's ISO 9001-2008 certified laboratory in North Vancouver, BC, Canada for analysis. A QA/QC program was implemented as part of the sampling procedures for the exploration program. Duplicate, standard and blank samples were randomly inserted into the sample stream prior to being sent to the laboratory.
About Riverside Resources Inc.:
Riverside is a well-funded prospect generation team of focused, proactive gold discoverers with the breadth of knowledge to dig much deeper. The Company currently has approximately $10,000,000 in the treasury and fewer than 34,000,000 shares issued. Riverside's model of growth through partnerships and exploration looks to use the prospect generation business approach to own resources, while partners share in de-risking projects on route to discovery.
