Riverstone Intersects High Grade Gold at Karma
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/23/11 -- Riverstone Resources Inc. (TSX VENTURE: RVS)(FRANKFURT: 3RV) reports results of three diamond drill holes from the Goulagou II deposit, part of the company's Karma Project in Burkina Faso, West Africa. Significant results include intercepts of 30 metres grading 3.70 g/t gold in Hole DD-10-002 and 60 metres grading 2.42 g/t gold in Hole DD-10-007. The holes were drilled in 2010 for geotechnical purposes and the results illustrate the high grade nature of the mineralized shoots that comprise the Goulagou II deposit. A diamond drill has been mobilized to Goulagou II to test these shoots at depth.

002 and 007 appears to be about 30 metres.
'We are pleased with these high grade results,' commented M.D. McInnis, President and CEO of Riverstone. 'They support the geological model developed during the work on our recent resource estimate which shows a number of high grade shoots within the overall Goulagou mineralized zone. These shoots warrant aggressive drilling down plunge. With $6.0 million in our treasury we are well financed to carry out this drill program.'
These three holes were drilled to collect geotechnical information for mine planning purposes within the known mineralized zone. A fourth hole, Hole DD-10-004, was drilled outside the zone to collect geotechnical information for pit wall stability purposes.
The Goulagou II deposit is part of the company's Karma Project 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.
