Riverstone Resources Inc.: New Exploration Permits in Bissa Area of Burkina Faso

VANCOUVER, BRIITSH COLUMBIA--(CCNMatthews - March 22, 2006) - Riverstone Resources Inc. (the "Company") (TSX VENTURE:RVS) is pleased to announce that it has entered into an option agreement to earn a 90% interest in two additional permits in the Bissa area of Burkina Faso. The Tangapella permit, comprising 248 square kilometres, is located on the eastern edge of High River Gold's Bissa property. High River has recently announced drilling results on the Bissa property which include high-grade intercepts of 39.4 g/t gold over 10 metres and 59.2 g/t gold over 9.1 metres. The Bissa deposit is located within the Sabcé Shear Zone which extends northeasterly from High River's property onto Riverstone's Tangapella permit (see attached location map). Sabila, the second permit, is also located on the eastern boundary of High River's property and overlies a 15 kilometre portion of a shear zone which parallels the Sabcé Shear Zone.

"We are very excited to have acquired these two key permits in the promising Bissa area," stated Michael D. McInnis, President of Riverstone. "The Tangapella permit in particular appears to be highly prospective. The permit is transected by about 20 kilometres of the Sabcé Shear Zone. Geochemical soil anomalies discovered by previous operators suggest the presence of gold mineralization and structural folds provide excellent sites for gold emplacement. We plan to commence aggressive fieldwork on these permits next month to develop drill targets."

Under the terms of the Option Agreement the Company can make cash payments totalling US$140,000 over three years for the two permits and incur sufficient exploration expenditures to satisfy the minimum requirement under the Mining Law (approximately US$250,000 per annum). After making the payments and incurring the expenditures, the Company will have earned a 90% interest in the permits. The vendors will retain a 10% interest, which will be carried by the Company until the formation of an Operating Company to take the project into production.

Riverstone holds nine other permits in Burkina Faso, which it has been actively exploring for the past three years.
