Riverside Resources and Partner Choice Gold Corp. Intersect 9.91 Metres of 1.76 g/t Gold in Newly Discovered Oxide Zone At the Sugarloaf Peak Gold Project in Arizona, USA

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 10/06/11 -- Riverside Resources Inc. ('Riverside' or the 'Company') (TSX VENTURE: RRI)(PINK SHEETS: RVSDF)(FRANKFURT: R99) is pleased to announce with its partner, Choice Gold Corp. ('Choice') the discovery of a new oxide gold zone at the Sugarloaf Peak Project ('Sugarloaf'), near Quartzsite, Arizona. Diamond drill hole SLG-11-04 returned a 9.91 metre intercept of 1.76 g/t gold between a depth of 5.3 and 15.24 metres. The discovery hole is located approximately 1 kilometer northeast from the core of the historically known mineralized zone.

'The shallow oxide portion at Sugarloaf Peak has identified favourable near surface mineralization and has expanded the potential for the Project moving forward,' stated John-Mark Staude, President and CEO of Riverside Resources Inc. 'The results from Sugarloaf are the first reported from four partner funded drill programs that were undertaken during the summer, and shareholders can now expect a steady flow of drill results throughout the fall,' added Staude.

Riverside currently holds 8.6M shares of Choice Gold (News Release, May 5, 2011), and stand to receive an additional 5M shares over the course of the option agreement pursuant to the deal terms. For more information on Riverside's projects or its partnership network please visit www.rivres.com.

Gold in drill hole SGL-11-04 occurs in a strongly oxidized interval of faulting and tectonic brecciation. Iron oxides are dominated by hematite and jarosite; no sulphides are observed. Some scattered quartz crystals observed along the interval suggest that the host rock could be a strongly altered felsic volcanic rock, the dominant lithology present on the property. Drill holes SGL-11-01 and SGL-11-02 returned anomalous gold values in the top 200 meters with grades averaging 125 ppb hosted by a series of sericitized felsic volcanic units. These values show the strength of the mineralizing system. Sporadic gold values reach 0.78 g/t in hole SGL-11-01 and 0.53 g/t in hole SGL-11-02. The discovery of gold associated with hematite alteration, not previously described on the property, creates a new type of exploration target and will influence the next phase of proposed drilling.
