Riverside Develops High Grade Silver Targets at Recently Staked Clemente Project

RIVERSIDE DEVELOPS HIGH GRADE SILVER TARGETS AT RECENTLY STAKED CLEMENTE SILVER-GOLD PROJECT IN SONORA, MEXICO
September 28, 2010 – Vancouver, BC: Riverside Resources Inc. ("Riverside" or the "Company") (TSX-V: RRI) is pleased to announce that it has completed an initial field work program on its newly staked, 100% Riverside-owned Clemente Silver-Gold Project in NW Sonora, Mexico and discovered high grade silver exceeding 2 kg/t (60 oz/t) in outcrops. Portions of the old workings and neighbouring outcrops were chip sampled early in the summer season. The program consisted of 152 rock chip samples and returned assay values from < 5 g/t up to 2,900 g/t silver and gold values from 5 ppb up to 5.4 g/t. Multiple samples returned values over 500 g/t silver, which is uncommon for this region of Mexico and indicates a potentially highly significant target. The drill ready exploration targets on the 142 km2 area property are shown on the maps provided in this release and on the Riverside website.
Riverside’s exploration team acquired the project in the Megashear Gold Belt of Sonora, Mexico through its Prospect Generation Program using its mineral property databases and proprietary targeting approaches. The Mojave-Sonora Megashear, on which Clemente is located, is one of North America’s major gold producing belts. The belt is relatively underexplored and has been a strong focus for Riverside’s technical team, having worked over the past two years to build a strong land position, including the Tajitos-Tejo and other properties. The Clemente Project is a mere seven (7) kilometers northwest of the Cerro Colorado mine operated by Goldgroup Mining Inc. and is within 100 kilometers of four other active gold-silver mines. The Project has exceptional infrastructure with power, water and road access making the targets easily accessible and relatively inexpensive for future drill testing and potential mining.
“With Clemente, we continue to expand our property portfolio, acquiring high potential assets that build shareholder value. Following our prospect generator business model, we look forward to partnering the Clemente Project and hope to have drilling begin quickly in hopes of exposing shareholders to discovery,” stated John-Mark Staude, President and CEO of Riverside Resources Inc. Staude added “finding multi-gram gold and multi-kilogram silver from outcropping targets is something we dream of and we are pleased to own this project for Riverside.”
The Project is dominated by strong hydrothermal alteration, breccias and veining in a basement rock sequence of Precambrian / Cambrian meta-sediments and Precambrian granites that have been multiply sheared with abundant stockwork quartz veining, similar to other areas of the Mojave-Sonora Megashear. Mineralization hosting sediments are primarily dolomites and arenites that have varying extents of alteration suggesting different depths of possible emplacement of mineralization. The Precambrian granites are composed of a 1.8 Ga and a 1.1 Ga suite, reflected in textural variations. These wall rocks act as brittle and locally reactive hosts to epithermal and mesothermal hydrothermal metal bearing fluids that deposited abundant silver along with gold and local base metals.
The primary metallic exploration target is adjacent to abandoned mines and along major through-going shears with extensive silver mineralization. The silver values are of particular note because of pure precious metal zones, as well as silver with base metal target zones. Results were drawn from numerous stockwork veins with variable strikes and dips that indicate high potential for stockwork with wider disseminated mineralization along the greater than 10 km long Clemente master shear and mineralized structure. The veins have historic workings only within the upper oxide zones with minor relict sulfides. The veins can now be tested further through geophysics, trenching, and follow up drilling.
The western Sonora districts have high potential to host orogenic, epithermal and replacement styles of mineralization. Clemente shows evidence of all three styles. The new 142 km² property has three outcropping target areas, each of which has previous mining history and one alluvium-covered silver-gold target. The two main mineralized zones that have been identified at Clemente, known as Nuevo Mundo and Santa Elena, are clearly outlined on the map below. The third high potential target area has a magnetic anomaly under shallow cover just north of the high grade gold and silver outcrops. Clemente has the potential to host a bulk tonnage deposit of silver and gold as well as high grade veins and replacement bodies similar to other mines in the region, and typical of what has made Mexico a world leader in silver production for over four centuries.

QA-QC Procedures: The Company has maintained a quality control program to ensure best practices in sampling and analysis in all its exploration programs. Duplicates, standards and blank samples are randomly inserted into the sample stream. Samples were delivered in secure, sealed bags to the assay labs for analysis. Gold is determined by fire assay with atomic absorption finish. The assay results were produced by Inspectorate Laboratories Ltd.
