VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 23, 2010) - Riverstone Resources Inc. (TSX VENTURE:RVS - News; FRANKFURT:3RV - News) is pleased to announce the commencement of the drilling program at its promising Nami artisanal site in Burkina Faso. The program will comprise 9,000 metres of RC drilling in approximately 70 holes. An initial 3,000 metres will be drilled at the Nami site and the rig will then be mobilized to the Company's nearby Rambo and Goulagou gold deposits to drill about 1,000 metres. Once the results from the initial drilling at Nami have been received the rig will be re-mobilized to the site to complete the RC drilling program. The drilling will take about two months to complete with first assays expected in mid-April.
Drilling will commence in the central portion of the artisanal site and proceed southerly on lines spaced 50 metres apart. At least three holes will be drilled on each line. The drilling will be testing a breccia body identified during the Company's recent shaft sampling program. The breccia body appears to strike northwesterly and to dip gently to the southwest. Overlying the breccia is a granodiorite and underlying the breccia is either granodiorite or volcano-sedimentary rocks. There is some evidence that the breccia body may consist of more than one breccia stacked on top of each other.
Quartz veining is prevalent within the breccia body and to a lesser extent in the overlying granodiorite. Quartz veining within the breccia appear to have the same dip as the breccia. In the overlying granodiorite, the quartz vein and stockworks are at a high angle.
The Company maintains a rigorous quality control program involving the use of repeat assays, inserted blanks, and the use of certified standards from an accredited Canadian laboratory. All rock samples were assayed using standard fire assay with atomic absorption techniques, with samples grading in excess of 2.00 g/t gold re-assayed with a gravimetric finish, at the independent Abilab Burkina SARL laboratories in Ouagadougou, Burkina Faso, which is part of the ALS Chemex group.
Riverstone Resources Inc. is active in gold exploration in Burkina Faso, West Africa, where the company holds an extensive portfolio of six high quality exploration permits covering 2,300 square kilometres.
