Riverstone Reports 38 Metres Grading 5.6 g/t Gold From Karma

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 1, 2011) - Riverstone Resources Inc. (TSX VENTURE:RVS)(OTCQX:RVREF)(FRANKFURT:3RV) is pleased to report exceptional results from two diamond drillholes on the Company's Karma Project in Burkina Faso, West Africa. (See Map and Section on website: http://www.riverstoneresources.com/s/Maps.asp?ReportID=460008). Significant results include intercepts of 38 metres grading 5.60 g/t gold, and 36 metres grading 4.61 g/t gold. The two holes are part of an on-going diamond drill program designed to test the down plunge of high-grade "shoots" within the Goulagou II zone of the Karma Project. Two additional holes have been completed. Results are pending and will be reported when received.

"We are very pleased with the results of these initial holes," commented M.D. McInnis, President and CEO of Riverstone Resources Inc. "The geologic model developed during our recent resource estimate identified several high-grade shoots within the Goulagou II zone, and these results have supported this interpretation. We are particularly encouraged by the stacked nature of the mineralized lenses. Both drill holes have several thick, well-mineralized intervals. We now have six drills under contract and are planning a program of a minimum of 90,000 metres of drilling on the Karma deposit."

Significant intercepts are reported in the table below. Interpreted true widths range from 50% to 70% of drilled lengths. Core recoveries are good to excellent (all in excess of 80%, mostly 100%).

The Goulagou II zone is part of the Company's Karma deposit which hosts a NI 43-101 compliant gold resource of 810,000 ounces of gold in the indicated category and 1,119,100 ounces in the inferred category (see news release dated February 28, 2011). The Goulagou property is subject to an Option to Purchase agreement with Golden Star Resources Ltd.

Riverstone maintains a quality control program involving the use of repeat assays, inserted blanks and the use of certified standards from an accredited Canadian laboratory. All core samples were assayed using standard fire assay with atomic absorption techniques, with samples grading over one gram gold per tonne 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 projects covering 2,300 square kilometres.
