VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec 20, 2013) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI)(PINKSHEETS:RVSDF)(FRANKFURT:R99) is pleased to announce that through its wholly owned subsidiary, Riverside Resources Mexico, S.A. de C.V., the Company has signed an agreement with Paget Southern Resources S. de R.L. de C.V. ("Paget"), a wholly owned subsidiary of Pembrook Mining Corp., granting Paget the option to earn up to a 100% interest in the Coatan Gold Project (the "Project"). In order to earn an initial 70% interest, (the "Initial Option"), Paget will have to incur $1,800,000 in exploration expenditures over four (4) years and make $27,460 in cash payments to Riverside. Upon exercising the Initial Option, Paget will have the option to acquire the remaining 30% by paying $1,500,000 in cash to Riverside within one (1) year (the "Additional Option"). In the event that Paget acquires a 100% interest in the Project, Riverside would retain a 2% Net Smelter Return (NSR) royalty, or if either party's interest falls below 10% it will be converted to a 2% NSR.

The 131 km² Coatan Project is located in Chiapas, the southernmost state in Mexico. Riverside staked the property and completed initial reconnaissance exploration work in 2011. Mineralization on the Project displays vuggy quartz, alteration minerals, and trace elements that suggest high-sulfidation epithermal precious-metals systems. There are three main zones of interest on the Project so far; Naranjo, Mirador and Vereda. These anomalous zones were identified by anomalous stream sediment samples, whose drainage basins are about 5 kilometres long by 3 kilometres wide. Initial field exploration on the Project has returned several noteworthy float samples of greater than 1 g/t and up to 5.2 g/t gold with textures indicative of high-sulfidation style mineralization in these samples.

Riverside President and CEO, John-Mark Staude, commented: "We are pleased to have the Coatan Gold Project move ahead with partner-funded exploration focused on delineating the highest priority drill targets for future testing and to carry the exploration and concession costs. Riverside continues to focus its efforts in north and central Mexico where the Company maintains its Mexico head office (Hermosillo, Sonora) and has major funding support from its alliance partners Antofagasta and Hochschild."
