Riverside Resources and Alliance Partner Antofagasta Commence Spring Exploration Program in British Columbia

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 6, 2012) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI)(PINKSHEETS:RVSDF)(FRANKFURT:R99) and its partner, Antofagasta Minerals S.A. ("Antofagasta"), are pleased to announce that exploration work is now underway at the Flute and Lennac Designated Properties located near Smithers in Central British Columbia (BC). The airborne magnetics, field sampling, logging of drill cores and targeting work are all designed to follow up on known porphyry copper mineralization and extend toward new copper porphyry targets.

Fieldwork for the 2012 season has now commenced on the Flute and Lennac Properties, with initial geological mapping and geochemical rock sampling being undertaken over prospective areas within the claims. Riverside has also retained contractors for diamond drilling, Induced-Polarization (IP) ground geophysics and Reverse-Circulation (RC) drilling to be completed on select areas within the Designated Properties. Applications for permits for the 2012 work-program have been submitted and mechanized work - RC drilling, ground geophysics and diamond drilling - will commence once permits are received.

An airborne geophysical survey has been flown by Aeroquest Limited over the Flute and Lennac Properties, for a total of 4532.4 line kilometers of airborne magnetics coverage over the full extent of both properties. Preliminary results have been received from Aeroquest, and several key structures and lithological domains not seen in regional geological maps have been delineated. Riverside has retained the services of Mira Geoscience to complete 3D unconstrained magnetic inversions on the data to create a 3D magnetic susceptibility model in MAG 3D from UBC-GIF.

Riverside and Antofagasta have planned a 2012 exploration program on the Flute and Lennac Properties consisting of both targeted diamond drill testing of areas of known copper-porphyry mineralization and of regional exploration throughout the claims. Highly prospective regional targets delineated through geological and geophysical interpretations will be tested with shallow, base-of-till/top-of-bedrock RC drilling and with widely spaced, reconnaissance-style lines of IP ground geophysics.
