February 28, 2011 – Vancouver, BC: Riverside Resources Inc. ("Riverside" or the "Company") (TSX-V: RRI)is pleased to announce that CLI Resources Inc. (“CLI”) and Riversides Resources Inc. have entered into an option agreement whereby CLI can acquire a 100% interest in the Company’s Sugarloaf Peak Project in Arizona (the “Property”). In order to exercise the option CLI must issue Riverside an aggregate 13,600,000 CLI shares, make total cash payments of $1,750,000 to Riverside, and incur $5,500,000 in exploration expenditures on the Property within 36 months of the agreement. The issuance schedule of CLI common shares will be such that Riverside will maintain a significant ownership interest in CLI Resources’ issued and outstanding shares. CLI must complete a National Instrument 43-101 compliant independent resource estimate on the Sugarloaf Peak Project within two years and a preliminary independent scoping study within three years of the agreement to fulfill the closing of the option. The independent resource estimate and preliminary scoping study requirements are both subject to an acceleration clause as detailed in the Additional Agreement Terms section below.

Riverside advanced the project through initial drilling and is pleased to now see the project de-risked and advanced by working with a partner that will take on major drilling and exploration campaign to test the depth, width, and grades of this large epithermal gold district. CLI will complete metallurgy and move the asset forward toward a compliant 43-101 resource, and immediately take over responsibility for payments to underlying owners such that Riverside would own the project outright should CLI not complete the full option agreement. Riverside will retain 100% interest until earn-in is complete and will hold a major interest in the asset through ownership in the new company should CLI complete earn-in.

“This agreement is another excellent step for Riverside as the Company continues to leverage the strength of its portfolio to unlock value and advance several assets simultaneously. Riverside recently announced a multi-asset JV deal with firm drill commitments in Durango, the commencement of a JV work program in Guerrero, and now the Company has delivered a major deal to advance Sugarloaf Peak,” stated John-Mark Staude, President and CEO of Riverside Resources Inc. “Sugarloaf Peak has a large low grade gold concentration and we are delighted to partner with CLI as they will put the financial resources forward to explore and expand the gold resource and bring it to a NI 43-101 compliancy” comments Staude.

Property Details and Planned Exploration:

The Sugarloaf Peak Project covers over 10 km² located west of Quartzsite, Arizona. Intermittent drilling and small-scale placer gold and lode gold mining occurred on the property during the 1950's and through to the 1990's. The Project is the subject of an historic, non-National Instrument 43-101 compliant mineral resource. In 2009, Riverside completed a drill program on the Property that substantiated a portion of the historic data, while testing the geologic model to twice the depth of previous gold exploration. Drilling targeted the southern portion of a 4 km² surface gold anomaly and left vast areas still open, which will now be the focus of exploration by CLI. Riverside completed five angled diamond core drill holes on the property for a total of 1,125 meters to a maximum true depth of 200 meters in any one hole. The core is now available for CLI to begin metallurgical work as well as target the next phase of drilling.

Previous exploration work by Riverside produced surface assay results from <0.005 g/t to more than 6 g/t gold. The new work by CLI will seek to find this type of higher grade gold in feeder structures through an extensive drill campaign. The planned drilling by CLI could more than quadruple the historic drill testing, and combined with a scheduled aeromagnetic survey and proposed IP program this future work has the potential to outline a much larger system in multiple directions.
