Riverside Resources Files for 350 Km2 Concession Covering Much of the Penoles District, Durango, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 19, 2008) - Riverside Resources Inc. (TSX VENTURE:RRI) is pleased to announce that it has filed for a 350 km2 exploration concession in the Penoles Mining District, Durango, Mexico. The claim surrounds the previously announced El Capitan mineral property and nearly doubles the Company's total land position in Mexico.

"The addition of 35,000 hectares to our existing El Capitan mineral concession represents a significant opportunity for Riverside," said John-Mark Staude, President and Chief Executive Officer, Riverside Resources. "The Penoles District is located in central metalliferous belt of Durango where the very successful Penoles Mining Company made its first discovery. Our El Capitan property has high potential for a hot spring gold deposit and our exploration team has identified a number of exploration targets within the new concession."

The El Capitan property is a hot spring type gold property in Durango, Mexico located near recent discoveries at San Augustin (Geologix), Penasquito (Goldcorp), Juanicipio (MAG Silver) and Camino Rojo (Canplats) in the same Durango-Zacatecas metalliferous belt. Previous drill programs have intersected gold mineralization at Capitan and surface programs have identified gold-bearing surface samples extending more than a kilometer. Riverside is completing an IP field survey and undertaking surface sampling and mapping in preparation for a drill campaign.

The Penoles Mining District has a diversity of deposit types, including the Jesus Maria Pb-Zn-Cu vein system, San Rafael Ag sulfosalts vein system and El Capitan hot spring and gold veining system. Skarn-type mineralization is also found at the La Purisima mine in the district. This type of superposition of diverse mineralization styles is common in major mining districts of Mexico (Staude and Barton, 2001).

Riverside operates with a generative exploration business model using experienced local prospectors, explorers and geologists to identify and acquire high quality mineral opportunities. Riverside looks for the most cost effective ways to build share value. To date, Riverside has announced four property acquisitions in Mexico which are summarized at www.rivres.com, and continues building a diverse mineral property portfolio.
