January 31, 2012 – Vancouver, BC: Riverside Resources Inc. ("Riverside" or the "Company") (TSX-V: RRI) is pleased to report that an initial five hole drill program has commenced at the Pedernal Project in Durango, Mexico. The main focus of the program will be the Tablones Norte Vein, where the recent trenching and soil sampling returned encouraging results (News release January 24, 2012). The program also proposes to test the Milpas Vein structure with at least a single drill hole. Drill holes will vary from 200 to 400 metres in depth with angles of -50° to -60°.

“Drilling at Pedernal is on schedule and will test the second property with Mexigold as we also look forward to upcoming drill results from the Catrina Property. These properties are both in favourable gold-silver regions and show promise as high quality drill targets,” stated John-Mark Staude, President and CEO of Riverside Resources Inc.

Drill Program Objectives and Details:

The large vein sets at the Pedernal Project show indications of the upper portion of a low-sulphidation epithermal precious metal system. The proposed drill program aims to test the Tablones Norte and Milpas structures in zones where the structural setting along with the geochemistry sampling (rock and soils), IP resistivity survey and fluid inclusions study confirms coincident anomalies.
