Riverstone Continues to Intersect Numerous Higher Grade Gold Zones at the Kao Zone on the Karma Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 12, 2011) - Riverstone Resources Inc. (TSX VENTURE:RVS)(OTCQX:RVREF)(FRANKFURT:3RV) is pleased to report results from nineteen reverse circulation ("RC") drill holes on the 100% owned Kao Zone, which forms part of the company's flagship Karma Gold project in Burkina Faso, West Africa. (See Map at http://www.riverstoneresources.com/i/maps/111208-091112_Kao_Plan.jpg). This drilling is part of a major on-going 90,000 metre Karma Project drill program designed to confirm the continuity of mineralization and also extend the mineralization to depth and along strike. These results have extended the known mineralization along strike in both directions and also down dip.

Mineralization at Kao has now been defined over a distance in excess of 850 metres north-south and 800 metres down-dip to the east. The deposit remains open down-dip and to the north-east and to the south. Several satellite zones remain to be drill tested.

Significant assay intervals are as follows:

  • 1.49 g/t Au over 28 m in RC-222
  • 2.10 g/t Au over 16 m in RC-229
  • 1.42 g/t Au over 12 m and 1.15 g/t Au over 12 m in RC-230
  • 1.45 g/t Au over 18 m in RC-240
  • 1.06 g/t Au over 16 m in RC-242
  • 1.63 g/t Au over 10 m, 1.84 g/t Au over 8 m and 1.42 g/t Au over 24 m in RC-247

"We are happy to see that numerous higher grade gold zones are extending the deposit along strike in both directions and down dip", commented Dwayne L. Melrose, President and COO of Riverstone. "The company will continue to extend and upgrade the resources for future engineering and economic studies that will be completed within 2012".

A more complete summary of significant results is presented in the following table:

Note: Interpreted true thicknesses for these holes are between 85 and 100 percent. Holes RC-225, RC-227 and RC-238 reported only low grade values. Assays are pending for holes RC-231 to RC-237 inclusive.

The 100% owned Kao deposit is part of the company's Karma Project which comprises a NI 43-101 compliant gold resource of 810,600 ounces of gold in 22,845,000 tonnes grading 1.10 g/t gold in the indicated category and 1,119,100 ounces of gold in 44,100,000 tonnes grading 0.79 g/t gold in the inferred category. (See news release dated February 28, 2011). Since the resource was calculated in February 2011, the company has drilled an additional +40,000 metres on the Karma project, and it is expected that the results of this drilling will add to the overall resource.

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 three high quality exploration projects covering +1,400 square kilometres.
