Vienna, Austria

Riverstone Resources Inc. (TSX-V; RVS) (“Riverstone” or the “Company”) is pleased to report results from seventy-one reverse circulation (“RC”) drill holes adjacent to the 100% owned Kao exploration permit (“Kao”) deposit, which forms part of the Company’s flagship Karma Gold Project in Burkina Faso, West Africa (the “Karma Project”). These holes were drilled to explore for new mineralized zones similar to that discovered at Kao, and lying to the north, north-east and south of the main deposit area. (See Map on the Riverstone Website for the location of the holes).

Significant assay intervals in these RC holes include:

For the south extension area:

• 1.80 g/t Au over 8 m in RC-325
• 1.58 g/t Au over 10 m in RC-336
• 1.20 g/t Au over 26 m in RC-265
• 1.05 g/t Au over 14 m in RC-269
• 16.0 g/t Au over 2 m in RC-282
• 3.94 g/t Au over 2 m in RC-279

For the north-east reconnaissance area:

• 3.67 g/t Au over 2 m and 1.16 g/t over 2 m in RC-297
• 1.38 g/t Au over 2 m and 0.90 g/t over 10 m in RC-308
• 0.96 g/t Au over 6 m including 1.72 g/t over 2 m in RC-216
• 0.75 g/t Au over 10 m including 1.48 g/t over 4 m in RC-215

Mineralization in the main Kao deposit now extends over 1,500 metres in a northeast-southwest direction and at least 900 metres down-dip to the east. The recent drilling to the south has extended the mineralized zone by about 100 metres. The Kao deposit is remains open in all directions.

Drilling to the north and north-east of the main deposit was widely spaced, and was more reconnaissance in nature. A newly defined zone of mineralization occurs some 500 metres east of the northern extent of the main Kao deposit as presently understood. Several of the holes within this 300 metre by 300 metre area returned shallow intersections of material in excess of the presently projected cut-off grade for oxide material. Further drilling will be completed to expand and define this new zone.

“We are very pleased with the discovery of the new mineralized zone as the size of the Kao deposit continues to grow”, commented Dwayne L. Melrose, President and CEO of Riverstone. “We have not yet found the limits of the Kao deposit and there is very good potential to expand the mineralization to the north as the gold in soil anomaly extends 4 kilometres further to the north. We expect to have these results reflected in the upcoming resource update, slated to be available for released this quarter.”

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. The Company’s flagship project is the 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 Company's 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 resource estimation, the Company has completed in excess of an additional 85,000 metres of drilling on the Karma Project, and it is expected that the results of this drilling will add to the overall resource of the Karma Project deposits for which a new resource estimate is expected to be released this quarter. The results of a Preliminary Economic Assessment have recently been released (see Company news release dated August 20, 2012 and NI 43-101 Technical Report titled, “Preliminary Economic Assessment Report for the Karma Project, Burkina Faso, West Africa”, with an effective date of August 2, 2012, filed on SEDAR (www.sedar.com) September 17, 2012), highlighting the Karma Project to be a robust project.

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.

Forward-looking information is based on various assumptions including, without limitation, the expectations and beliefs of management, the assumed long term price of gold, that the Company will receive required permits and access to surface rights, that the Company can access financing, appropriate equipment and sufficient labour and that the political environment within Burkina Faso will continue to support the development of environmentally safe mining projects. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements. Accordingly, readers are advised not to place undue reliance on forward-looking statements.
