Riverside Resources Receives Additional $300,000 in Target Definition Funding from Alliance Partner Hochschild Mining to Advance Riverside's Clemente Project, Sonora, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sep 9, 2013) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI) (PINKSHEETS:RVSDF) (FRANKFURT:R99), is pleased to announce that an additional $300,000 has been received from its alliance partner, Hochschild Mining plc ("Hochschild"), for target definition at the Company's Clemente project in Sonora, Mexico. The additional funds will be used to carry out further mapping, geochemistry and trenching work this fall to refine targets ahead of potential drill testing in early 2014. Target Definition funding will provide Riverside and Hochschild an opportunity to further evaluate and advance Alliance properties as potential Designated Projects (DP's) before entering the earn-in stage of the agreement. Once a project is selected as a DP, Hochschild can earn a 65% interest by spending $5M in exploration over four years and making a one-time cash payment to Riverside of $3M.

Riverside's President and CEO, John-Mark Staude stated, "Riverside is pleased to be forwarding the Clemente Project and following up on initial exploration work previously completed by Riverside geologists. Previous work identified strong gold and silver values and we are confident that this current target definition program will outline quality drill targets for future testing. This area of Sonora has good surface access, is readily workable year round, and is in sight of open pit gold mines."

Exploration Program Details:

There are several important structural intersections at Clemente which require detailed attention from mapping and sampling to understand the structural controls on mineralization. The current field program will include detailed mapping and rock chip sampling, which will quickly identify areas for soil sampling lines and ground mag geophysics. These will guide the placement of trenches to expose mineralized zones of interest. Detailed mapping of surface and trench exposures will include lithological, structural and alteration mapping to understand the character, distribution, and controls on mineralization. Drill targets will be developed based on the resulting data.

About the Clemente Project:

The 100% Riverside-owned Clemente Project was identified and acquired using Riverside's 66,000 mineral location proprietary database. The Project is located in the heart of the Sonora Megashear and only 7 km from the Cerro Colorado Mine. Previous field work completed by Riverside discovered high-grade silver exceeding 2 kg/t (58 oz/t) in outcrops.

The previous work program (News release September, 28, 2010) consisted of 152 rock chip samples and returned silver assay values from <5 g/t up to 2,900 g/t Ag and gold values from <5 ppb up to 5.4 g/t Au. Numerous rock chip samples returned values over 50 g/t silver, which is uncommon for this region of Mexico and warrants further follow-up work to refine initial target concepts and develop a proposed plan for potential drilling. The Project has excellent infrastructure with power, water and road access making the targets easily accessible and cost effective for future exploration and development.
