1.25 km Surface Gold-Silver Anomaly Identified at Riverside Resources Inc.'s Libertad Gold-Silver Project, Sonora, Mexico by Partner Geologix Explorations Inc.

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 16, 2010) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI) is pleased to announce results from the Libertad Gold-Silver Project in Sonora, Mexico as reported by Geologix Explorations Inc. ("Geologix") (TSX VENTURE:GIX). The property is currently under option by Geologix, and as operator, Geologix completed the Phase One geochemical rock sampling and hand trenching program on the 160 km2 property. The program identified a large gold-silver anomaly on surface with a strike length of 1.25 km. Geologix's exploration work discovered significant gold and silver results ranging up to 9.91 grams per tonne (g/t) gold and 230.3 g/t silver over 3.50 metres (m). Highlights also include 2.23 g/t gold and 52.5 g/t silver over 13.10 m, and 1.27 g/t and 42.4 g/t silver over 11.70 m in different trenches that cross the northwest trending mineralized structure. Recent mapping, sampling and trenching work identified consistent geochemical gold results which have assisted in the identification of initial drill targets. These targets are being evaluated through a geophysical survey and mechanical trenching program that Geologix anticipates to complete in the coming months.

John-Mark Staude, President and CEO of Riverside, stated: "We are pleased with Geologix's work on the property and their recent completion of mapping, sampling, trenching, and drill target identification. These gold results expand upon and exceed the gold and silver assay values that Riverside had found and is a positive step for the project. We are pleased to see that drill targets are being identified, and look forward to additional work to further the exploration on the property and to move towards drill testing in order to evaluate the anomalies below surface."

The Libertad project is located 250 kilometres (km) northwest of Hermosillo, Sonora, Mexico, and represents a structurally controlled gold-silver mineralized system. Geologix can earn up to an 85% interest in the project from Riverside through a series of staged payments to Riverside totaling US$900,000 and work expenditures of US$5,000,000 over a period of six (6) years.

Riverside's exploration on the project was limited to rock grab and chip sampling. As reported by Geologix in a news release dated March 16, 2010, the recent systematic program of channel sampling and hand trenching at 50 metre intervals along strike collected a total of 639 samples, with highlights shown in Table 1 below. A map showing the locations of trenches can be found on Geologix's company website (www.geologix.ca).

The hydrothermal mineralized system remains open along strike, and the multiple trenches cut across the system remain open at both ends. Follow up mechanical trenching and sampling to better determine both the width and strike of the system is expected to commence in the coming months. In addition, a central core area focused induced polarity (IP) geophysical survey has been initiated over the 1.8 km by 1.0 km central grid area of the system. Highlight results as reported by Geologix are as follows:
