July 19, 2010 � Vancouver, BC: Riverside Resources Inc. ("Riverside" or the "Company") (TSX-V: RRI) is pleased to announce that its partner Geologix Explorations Inc. (�Geologix�) has intersected gold in the first two drill holes of a proposed 2,000 metre (�m�) program on Riverside�s Libertad Gold Project in Sonora, Mexico. Geologix, who has the Project under option from the Company, announced initial drill assay results from the first two Diamond drill holes of the first ever drill program on the property (Geologix News Release July 19, 2010). As reported by Geologix, assay results include intercepts of 26.05 m of 1.02 grams/tonne (g/t) gold and 65.10 g/t silver starting at 45.65 m depth in the first hole, and 50.80 m of 0.51 g/t gold and 32.30 g/t silver starting at 48.6 m depth in the second hole. Drill holes 001 and 002 were collared along the northern extent of the 1.6 kilometre exposed gold and silver surface structure.

John-Mark Staude, President & CEO of Riverside, stated, �These are the first drill results from the Libertad Gold Project and we are excited to see thick intervals of shallow gold mineralization with significant upside along strike, width and depth. If the subsequent drilling successfully identifies consistent results there is potential for the identification of a mineable open pit oxide ore body. The project has excellent infrastructure, which could make exploration and drill out delineation rapid and cost effective.  We look forward to further results from the project as Geologix continues to drill the structure along strike to the south.�

On July 19, 2010 Geologix stated that the drill program will continue to trace the structure along strike, �the drill program at Libertad includes a proposed 2,000 metres of Diamond drilling. Initial holes have been designed to test the northern portion of the structure to determine the style and character of the mineralization, while subsequent holes will seek to trace the structure along strike to the south with additional shallow holes. Based on initial results, drilling will then test the structure at depth where geophysical surveys indicate the presence of a geophysical (IP) anomaly that widens to 700 metres at a depth of 125 metres.�

Assay results from the highlight intercepts from the first two holes include:

About the Project:

The Libertad project is located 250 km north-west of Hermosillo, Mexico.  The project represents an early stage exploration project hosting a gold-silver mineralized vein system that has seen no prior systematic advanced exploration or drill testing, and only limited previous rock grab and chip sampling.  Riverside acquired the property, staked more ground and developed targets then, as a Prospect-Generator company, brought in Geologix as a partner to move forward with the exploration program.

Geologix has completed its first year commitment of the first option on the Libertad Project and is accelerating its work on the project due to positive results. By spending $3,000,000 and paying Riverside $400,000 over four years Geologix can earn 60% of the project. Once the initial option is complete, Geologix has a second option to earn an additional 25% by spending another $2,000,000 on the Libertad property and making payments totaling $500,000 to Riverside within an additional two years.
