Riverstone Resources Inc. (TSX-V; RVS) (“Riverstone” or the “Company”) is pleased to report results from 14 diamond core (“DD”) drill holes on the 100% owned Kao Deposit (”Kao”), which forms part of the Company’s flagship Karma Gold Project in Burkina Faso, West Africa (the “Karma Project”). These holes are located in the southern portion of the Kao Main zone, and are part of a program of drilling designed to further explore and delineate near surface higher gold grade oxide mineralization.

Significant assay intervals in these drill holes include:

• 2.92 g/t Au over 32 m including 3.63 g/t Au over 14 m in DD-12-160

• 2.09 g/t Au over 32 m in DD-12-154

• 3.11 g/t Au over 18 m in DD-12-163

• 2.39 g/t Au over 8 m in DD-12-161

• 1.84 g/t Au over 28 m in DD-12-155

• 1.73 g/t Au over 14 m in DD-12-164

• 1.19 g/t Au over 22 m including 2.37 g/t Au over 8 m in DD-12-158

Mineralization at Kao now extends over 1,400 metres northeast-southwest and at least 900 metres down-dip to the east. These latest drill holes demonstrate the presence and continuance of zones of higher grade gold mineralization in the near surface oxide material. A large number of additional drill holes have been completed at Kao; assays are pending for this drilling and should be available for release during August and September.

“We are most encouraged by these higher grade assays from drilling at Kao”, commented Dwayne L. Melrose, President and CEO of Riverstone. “These results are exciting because they confirm the continuity of the higher grade near surface oxide material at Kao. We still have not found the limits of the overall Kao Deposit. We continue to expand Kao, and the results will be included in the upcoming resource estimate scheduled for September 2012. 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 100% owned Kao 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 data cut-off for the last resource estimation, the Company has completed an additional +85,000 metres of drilling on the Karma Project, including approximately 54,000 metres at Kao. 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.
