Riverside Resources and Alliance Partner Antofagasta Commence Exploration in Preparation for Drilling at the Swift Katie Porphyry Copper Project in British Columbia, Canada

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 27, 2014) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI)(RVSDF)(R99.F), is pleased to announce that spring exploration work has now begun at the Swift Katie Project (the "Project") located in south-eastern BC, with drilling to follow later in the summer. The first phase of the program has been designed with the goal of identifying new targets, as well as to advance known targets generated through the 2013 exploration program within the 11km x 3km target corridor of favourable geology, geochemistry and geophysics. Of particular focus for the 2014 program is a newly identified, high priority target located 2km south of the historically defined Katie copper-gold porphyry deposit. The newly identified "Swift" porphyry target is characterized by a 2km by 2km multi-element soil anomaly underlain by a favourable geophysical signature. This area has limited outcrop but porphyritic intrusive rocks and altered volcanic rocks were recognized by Riverside geologists within and adjacent to the target area.

This initial phase of 2014 exploration work will include the expansion of the soil grid started in October 2013, and will consist of approximately 300 additional soil samples covering the remaining 5km of strike length of the prospective corridor. Soil sampling will be coupled with prospecting and mapping at the Swift target and at regional targets along the trend. Historic drill core from the Swift and Katie showings will also be relogged as Riverside and Antofagasta work together to refine and rank targets for drill testing.

Riverside's President and CEO, John-Mark Staude, stated: "We are excited to get going with exploration in British Columbia (BC) and look forward to expanding on historic and known mineralization at the Swift Katie Cu-Au-Mo district. We believe there is plenty of exploration upside in the prospective corridor at Swift Katie. Progressing with our alliance partner, Antofagasta, funding the work, provides shareholders with low-cost potential for discovering and owning a major Cu-Au asset in BC."
