VANCOUVER, BRITISH COLUMBIA–(Marketwired – May 5, 2015) – Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI)(PINKSHEETS:RVSDF)(FRANKFURT:R99) announces that its partner Morro Bay Resources Ltd. ("Morro Bay") has exercised the option on the Peñoles Project (the "Project") by making the final payment of 15,000,000 common shares of Morro Bay. As a result, Riverside now has ownership and control over 28,841,109 common shares of Morro Bay, representing approximately 35% of Morro Bay's issued and outstanding shares.

The 15,000,000 common shares were issued by Morro Bay and acquired by Riverside pursuant to Morro Bay's exercise of its option to acquire a 51% interest in Riverside's Peñoles property, Mexico, under an Option Agreement dated January 22, 2014, and amended June 30, 2014, January 8, 2015, and March 31, 2015 (the "Option Agreement"). Accordingly, the 15,000,000 common shares were issued for a consideration equivalent to the percentage value that they represent of the total value of the payments, expenditures and other consideration required to exercise the option, as a function of the value of the mineral property interest acquired. No formal valuation has been conducted of the mineral property interest acquired, however the value ascribed to the 15,000,000 common shares in the Option Agreement was $750,000 in the aggregate, and equivalent to $0.05 per share.

Moving forward, Riverside will receive a $1,250,000 USD and $100,000 CAD credit towards initial Joint Venture Expenditures. Morro Bay will be required to incur a minimum of $750,000 CAD in Joint Venture Expenditures for each of the first three years. In the event that Morro Bay fails to meet the minimum required Joint Venture Expenditures, Riverside will have the right to take back 100% ownership of the Project, subject to certain conditions (see Agreement Details section in Riverside press release dated January 20, 2015).

Riverside's President and CEO, John-Mark Staude, stated: "Riverside looks forward to further partner funded exploration work and drilling to expand on the recently filed NI-43-101 Resource Estimate. We are pleased to be a major shareholder in Morro Bay and believe the collaborative advancement and de-risking of the Peñoles Project has positioned Riverside shareholders to participate in future upside at the Project and Morro Bay corporate level, while also allowing Riverside to focus on many other growth opportunities simultaneously. Riverside won't have to commit towards JV expenditures at Peñoles until approximately $2,700,000 in further work is funded by Morro Bay."
