Riverside Resources and Partner Choice Gold Complete Phase 1B Drill Program With Gold Intersections in an Area of 1 km X 300 m at the Sugarloaf Peak Gold Project in Arizona

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 5, 2012) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI)(PINKSHEETS:RVSDF)(FRANKFURT:R99) is pleased to announce the completion of the Phase 1B drill program, consisting of 13 reverse-circulation drill holes at the Sugarloaf Peak Gold Project, located in southwest Arizona, with partner Choice Gold Corp ("Choice"). The Phase 1B drill program highlights include gold intervals of up to 93 m @ > 0.4 g/t Au (News Release March 14, 2012) and most recently hole SGR-12-13, which intersected a thick sequence of mineralised felsic tuffs returning three mineralised intervals including 10.7 metres at 0.54 g/t Au. This news release highlights the final seven holes of the Phase 1B drill program. Completion of this phase of drilling brings the total number of drill holes completed by Riverside and Choice to 31 holes.

The calculated intervals for drill hole SGR-12-13 are presented in the following table. All intervals were calculated using a 0.15 g/t Au cutoff grade, a minimum thickness of 25 feet or 7.6 metres, and a maximum dilution thickness of 3.0 metres.

RC Hole No From
g/t Au
SGR-12-13 10.7 24.4 13.7 0.25
SGR-12-13 32.0 91.5 59.5 0.29
including 51.8 62.5 10.7 0.54
SGR-12-13 96.0 120.4 24.4 0.31
* Intervals represent drilled length; true thickness is unknown

These results indicate that the central mineralised zone that extends over 1.1 km along a NE-SW strike between SGR-12-09 and SGR-12-11 now has a minimum estimated width of 320 meters and depth up to 120 metres as outlined by core and RC drilling by Riverside and now Choice. RC drill hole SGR-12-13 was collared in strongly argillized tuff units with alteration similar to that observed in hole SGR-12-10, located 325 meters WNW of hole SGR-12-13, which returned 93.0 metres at 0.44 g/t Au, including 21.3 m at 0.53 g/t Au and 33.5 m at 0.51 g/t Au (News Release, March 14, 2012). Other notable drill holes are shown on maps and cross sections for the Sugarloaf Peak Project on the Riverside and Choice Gold websites. These include 114 metres @ 0.41 g/t Au (SGR-12-10), 93 metres @ 0.44 g/t Au (SGR-12-09), 9.9 metres @ 1.76 g/t Au (SLG-11-04), and 11.42 metres @ 0.73 g/t Au (SLP-09-02).

Riverside's President & CEO, John-Mark Staude, stated he was "pleased to see the gold assays from the RC drilling continue to demonstrate continuity of gold mineralization at the Sugarloaf Peak Project." Dr. Staude added, "Riverside looks to progress forward with Choice Gold to drill up a potential >500,000-ounce open-pit gold system."

The other 6 holes SGR-12-14 to SGR-12-19 were not located inside the mineralised area and did not return drill-hole intervals of significant thickness; however, isolated samples returned up to 1.2 g/t gold. The Phase 1B drilling campaign consisted of 13 reverse-circulation holes testing the historically known central mineralised area, as well as new areas to the west, south, and southeast. Results from hole SGR-12-13 show that the mineralised area is still open to the south and east; this area will be the subject of a subsequent drilling campaign.

Assaying and Qualified Person:

According to Choice Gold all of the RC holes were sampled successively from the top to the bottom of each hole following rigorous QAQC procedures. These QAQC procedures include the insertion of blanks, standards, and duplicates. All the samples were shipped to American Assay Lab, Reno, NV, to be pulverised and analyzed for Au by the fire assay method and for a suite of trace elements using the ICP method.
