(Source: MARKETWIRE)Riverside Resources Inc. (TSX VENTURE: RRI) ("Riverside" or the "Company") is pleased to announce that the Company has commenced drilling on its 100% controlled Sugarloaf Peak Gold Project in Arizona. This drill program will target mineralized zones within the non NI 43-101 compliant historic resource(i) (News Release Nov. 14, 2008) as well as new higher-grade zones (News Release September 9, 2009) outside of the historic resource area. One focus of the current drill program is to compare previous historic reverse circulation drill data with core drilling. This will add to the understanding of the geology and structure, and will further advance the project on its way to potentially becoming known as a significant gold system similar to that of the Mesquite Mine and other active gold mines in the region.

"The Riverside team has been active over the summer collecting samples from the project in order to confirm the presence of a large gold body at the Sugarloaf Peak Gold Project. This drill program will enable Riverside to substantiate some of the historic drill results as well as potentially identify new gold zones.", commented John-Mark Staude, President & CEO of Riverside, "By successfully managing the Company's joint venture business model, adding high potential properties to the portfolio and completing focused drill programs on the most exciting targets Riverside has continued to add value for shareholders."

The company has contracted Brown Drilling of Kingman Arizona to complete the 1000m diamond drill program on the Sugarloaf Peak Gold Project. The project will be drilled to a depth of approximately 200 meters in order to expand the depth of the known gold assays.

Technical Details:

The current drill program consists of five HQ diamond drill holes targeting a recently identified thick horizon of altered sulphidic "welded" rhyolite tuff and is associated with high grade surface gold values. These values have reached upwards of 11.83 g/t in recent rock chip sampling (News Release September 9, 2009). This unit appears to form the southern limb of an overturned anticlinal structure and has been traced for over 1km on surface.

Thus far the Company has encountered oxidation and leached sulfides consistent with surface alteration in the drill core. Samples are now being logged and split and Upon completion of the drill program the drill core will be sent for assay following 43-101 procedures. Results are expected by the end of December.
