Riverside Expands Exploration Targets at the Glor Gold Project in Sonora, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 4, 2016) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI)(OTC PINK:RVSDF)(FRANKFURT:R99), is pleased to provide an exploration update on recent exploration work at the Company's Glor Gold Project (the "Project"), located approximately 8 km west of Alamos Gold's El Chanate Gold Mine in Sonora, Mexico. Several large scale target areas have been identified over an area covering approximately 25 square kilometres, with further follow up work planned for 2016. Riverside will now seek a partner to advance this prospective gold target.

Riverside has completed several campaigns of exploration work on the property including detailed geologic and alteration mapping, rock chip and channel assays, orientation ground magnetic surveys, reprocessing of regional high resolution airborne magnetic surveys and most recently a soil sampling survey over the southwestern portion of the property. Riverside has collected 155 rock chip samples to-date, with assays from <0.005 g/t to 18.85 g/t gold (see press release September 3, 2015 for more details on past work). The Glor Project was initially optioned by Riverside while under a strategic alliance with Hochschild Mining Plc., and has subsequently reverted to Riverside control.

The recently completed soil sample grid covering the western portion of the property further defined target areas (San Pedro & El Poblado) worthy of additional field work ahead of drill targeting (visit the Glor Project Page to view target maps and figures). Gold assays from the soil sampling identified anomalous values in an area approximately 1,500 metres long by 700 metres wide, along the primary fault system that trends approximately west-northwest, dipping to the southwest. The soil samples were first tested using a handheld XRF Innovex analyser to determine levels of certain base and trace metals typical of these deposit types to identify areas of interest for detailed quantitative assay follow up.

Riverside's President and CEO, John-Mark Staude, stated: "We are encouraged by recent field work and look forward to working with a partner at the Glor Project in the near future."

Project History and Agreement Details:

The Glor Project was previously staked by Pediment Gold, which completed geologic mapping, rock sampling, and soil sampling. Pediment's soil sampling indicated several gold and trace-element anomalies coincident with surface alteration. Argonaut Gold bought Pediment Gold, acquiring Glor in the process. Riverside acquired the option to earn a 100% interest in the Project from Argonaut Gold (see press release March 25, 2015) as part of Riverside-Hochschild Alliance activities and now the Company is looking to advance the project with a new partner.

Soil samples were analyzed at the Bureau Veritas Laboratory (BVL) in Hermosillo Sonora. The samples were screened and pulverized to <140 mesh. BVL is an ISO 9001-2008 certified laboratory formerly known as the Inspectorate Laboratory. A QA/QC program was implemented as part of the sampling procedures for the exploration program. Standard and blank samples were randomly inserted into the sample stream prior to being sent to the laboratory.
