www.riverstoneresources.com TSXV: RVS Frankfurt: 3RV 2008.06.10 This presentation may contain “forward-looking information” within the meaning of Canadian securities acts or “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934 of the United States . Forward-looking statements are subject to a variety of risks and uncertainties which could cause actual events or results to differ from those reflected in the forward-looking statements, including, without limitation, risks and uncertainties relating to the interpretation of drill results and the estimation of mineral resources, the geology, grade and continuity of mineral deposits, the possibility that future exploration, development results will not be consistent with the Company’s expectations, accidents, equipment breakdowns, title matters and surface access, labour disputes, the potential for delays in exploration activities, the potential for unexpected costs and expenses, commodity price fluctuations, currency fluctuations, failure to obtain adequate financing on a timely basis and other risks and uncertainties, including those described under Risk Factors in each management discussion and analysis. In addition, forward-looking information is based on various assumptions including, without limitation, the expectations and beliefs of management, the assumed long term price of gold, that the Company will receive required permits and access to surface rights, that the Company can access financing, appropriate equipment and sufficient labour and that the political environment within Burkina Faso will continue to support the development of environmentally safe mining projects. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements. Accordingly, readers are advised not to place undue reliance on forward-looking statements. • Seven attractive gold projects in Burkina Faso, West Africa • Stable political climate with investor-friendly Mining Code • Financing at $0.60 and option rights granted to Teck Cominco • Karma project - current 43-101 total resource of 550,000 ounces gold - target of 1.25 million oz of gold in 2008* - potential for near-term, low cost gold production* • Ligidi project - extensive geochemical soils and rock boulder anomalies - boulders sampled averaged 2.33 g/t gold within a 1 g/t gold contour * This estimate is based on the potential for gold resources in all categories of some 20 to 25 million tonnes containing an estimated average of 1.5 g/t gold which in turn is based on a reasonable projection of the results to date from drilling the mineralized zones on the Goulagou, Kao and Rambo permits and from the existing NI 43-101 resource estimates for the Goulagou deposits. The figures are intended to provide an indication of management’s expectations and are conceptual in nature. To date, insufficient exploration has been undertaken to define this size of mineral resource and therefore it is uncertain whether the target will be delineated as a mineral resource or whether production will ensue. • Other projects Yaramoko, Bissa East, Bissa West, Solna and Tao - all located in greenstone belts with encouraging exploration results to date • 2008 drill programs underway to expand current gold resource and test other targets at Karma and Ligidi • Listed TSX Venture Exchange – RVS and quoted Frankfurt – 3RV • Recent share price ~ C$0.40 • Current market capitalization (fully diluted) ~ C$25.5 million Michael D.
