VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 08/03/12 -- Riverstone Resources Inc. (TSX VENTURE: RVS)(OTCQX: RVREF)(FRANKFURT: 3RV) ("Riverstone" or the "Company") is pleased to report results from 51 reverse circulation ("RC") drill holes on the 90% owned Goulagou I ("GGI") deposit, which forms part of the Company's flagship Karma Gold Project in Burkina Faso, West Africa (the "Karma Project"). These holes are part of the overall program to extend the GGI deposit along strike and to depth for inclusion in the upcoming resource estimate on the Karma Project, which is scheduled to be available in September 2012 (See Map on the Riverstone Website for the location of the holes: http://www.riverstoneresources.com/i/maps/120802-100504_GGI_Plan-b.jpg).
Significant assay intervals in these drill holes include:
-- 1.43 g/t Au over 40 m in 12-RC-339 -- 1.21 g/t Au over 20 m including 3.48 g/t over 4 m in 11-RC-321 -- 4.53 g/t Au over 4 m in 11-RC-328 -- 1.08 g/t Au over 14 m in 11-RC-330 -- 2.32 g/t Au over 2 m and 4.21 g/t Au over 2 m in 12-RC-236
Mineralization at GGI now extends over 2,200 metres east-west and locally at least 200 metres down-dip. Drilling at GGI is generally testing shallow targets, to about 100 to 150 metres vertical depth and also deeper drilling that test higher-grade shoots that remain open to depth and along strike.
"The results of this drilling will be included in the upcoming resource estimate scheduled for September 2012," commented Dwayne L. Melrose, President and CEO of Riverstone. "The Preliminary Economic Assessment for the Karma Project that is currently being conducted is progressing on schedule and is expected to be released in August 2012."

The 90% owned GGI deposit is part of the Company's Karma Project which comprises a NI 43-101 compliant in-pit Whittle indicated resource of 1.6 million ounces of gold in 47.3 million tonnes grading 1.1 g/t gold and an inferred resource of 0.6 million ounces of gold in 18.9 million tonnes grading 0.93 g/t gold (see news release dated January 9, 2012 and NI 43-101 Technical Report titled "Technical Report and Resource Estimate on the Karma Project, Burkina Faso, West Africa" filed on SEDAR (www.sedar.com) February 23, 2012). Since the cut-off date for the January 9th, 2012 resource estimation, the Company has completed an additional +85,000 metres of drilling on the Karma Project. It is expected that the results of this drilling will add to the overall resources of the Karma Project deposits.
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 samples were prepared at the independent Abilab Burkina SARL laboratory in Ouagadougou, Burkina Faso, West Africa (part of the ALS Chemex Group), and assayed using standard fire assay with an atomic absorption finish, with samples grading over one gram per tonne gold re-assayed with a gravimetric finish, either in Burkina Faso or at the ALS Chemex facility in North Vancouver, British Columbia, Canada.
Riverstone is active in Burkina Faso, West Africa, where it holds a portfolio of four high quality exploration projects covering in excess of 2,000 square kilometres.
