VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 21, 2011) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI)(PINK SHEETS:RVSDF)(FRANKFURT:R99) is pleased to announce that partner Choice Gold Corp. ("Choice") has commenced an initial 5,000 metre diamond drilling program at Riverside's 24 km² Sugarloaf Peak Gold Project ("Sugarloaf" or the "Project") outside of Quartz site, Arizona, USA. The first phase of drilling will target gold-bearing alteration zones and major structures recognized during the recent surface sampling campaign. The program is also designed to include deeper holes to test the 2.5 km long chargeability anomaly identified at depth during April's Titan 24 ground survey.

This is the third partner funded drill program now concurrently underway and Riverside shareholders can look forward to a steady stream of news flow and results ahead," stated John-Mark Staude, president and CEO of Riverside Resources Inc.
