VANCOUVER, BRITISH COLUMBIA — (Marketwire) — 06/21/12 — Riverside Resources Inc. (“Riverside” or the “Company”) (TSX VENTURE:RRI)(PINKSHEETS:RVSDF)(FRANKFURT:R99) reports that the option agreement whereby Mexigold Corp. (“Mexigold”) could earn an interest in the Catrina, Pedernal and Escondida projects (the “Durango Properties”) is being terminated and Riverside will retain 100% interest in the projects. Riverside is pleased to move ahead with the Durango Properties, while Mexigold has elected to pursue other business opportunities during these difficult market conditions. Two of the properties, Catrina and Pedernal, have been drilled with an aggregate $1.83 million in exploration funding from Mexigold, which builds upon the earlier exploration investment made by Kinross and Riverside.

Pedernal is located east of Silver Standard’s Pitarilla Mine and north of Argonaut’s open pit gold production at the Castillo Mine. Drilling at the Pedernal Project intersected the upper levels of a low-sulfidation epithermal system and demonstrated the potential for improved mineralization down-dip and along strike. Pedernal can be further drill tested based on the extensive trenching, sampling, and IP completed over the past year. All permits are in place and the property is easily accessible for low cost, efficient drilling to carry the next exploration discovery step with Riverside’s experienced team available to assist in the exploration process.

The Catrina Project is located east of the Santo Domingo Mining district and immediately west of the Km 66 silver gold resource and former mining area in the topographically flat Altiplano region of northern Durango. Only two of the seven drill targets at Catrina were drilled by Mexigold, and other high priority targets on the project are ready for a partner who wishes easy, cost effective, drive up exploration with all the access agreements in place, mineral title and extensive work completed to begin drilling within weeks of completing an option agreement.

The third property in the agreement, Escondida, has access permits, positive geology and a planned exploration and drill program ready for implementation. Due to Mexigold’s shareprice and the market conditions, Mexigold chose to not pursue the program, although the project has been worked up and is ready to go. Escondida is all set for a new partner interested in a turn-key discovery opportunity west of the Fresnillo mining district along a major mineralized geologic corridor. This property has strong IP conductors, surface gold and silver mineralization, former small prospects and magnetic highs typical of other precious metal systems in Mexico’s world class Silver Belt.

President and CEO of Riverside Resources, John-Mark Staude, commented: “We are pleased to have worked over the past year with Mexigold and now welcome these projects back into our portfolio as they have been advanced through this recent exploration. Collectively the targets have been refined, and mineralization characterized through field focused, cost effective exploration efforts.” Staude added, “Permits are in place to move ahead and there are a number of quality drill targets on these three properties. This is one of the more readily accessible and prolific mining terranes in North America. We look forward to unlocking the potential of this portfolio through new exploration partnerships.”
