VANCOUVER, BRITISH COLUMBIA–(Marketwired – Sept. 20, 2016) – Riverside Resources Inc. (“Riverside” or the “Company”) (TSX VENTURE:RRI)(OTC PINK:RVSDF)(FRANKFURT:R99) is pleased to provide an exploration update for ongoing work at the Thor Project (the “Project”) in Sonora, Mexico. Thor was staked by Riverside as part of the Company’s copper porphyry exploration alliance (the “Alliance”) with a wholly owned subsidiary of Antofagasta Plc. (“Antofagasta”). The Thor Project is being advanced as a Designated Project (“DP”), with Antofagasta having the opportunity to earn a 65% interest by funding $5,000,000 in exploration over four (4) years (see Riverside’s press release April 13, 2015). Riverside has received mineral title and signed access agreements. Company geologists, working in close collaboration with Antofagasta geologists, have completed initial detailed field mapping, prospecting and rock chip sampling. Results to-date are promising and have resulted in drill targets being defined, with initial drill testing now planned. This most recent phase of exploration was designed to work up target areas on the southern portion of the property.
