Riverstone Intersects 1.33 g/t Au over 52 Metres on the Karma Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 7, 2011) - Riverstone Resources Inc. (TSX VENTURE:RVS)(OTCQX:RVREF)(FRANKFURT:3RV) is pleased to report results from a further 21 Reverse Circulation ("RC") drill holes on the Goulagou I Zone, which forms part of the Company's flagship Karma Gold project in Burkina Faso, West Africa. (See Map at www.riverstoneresources.com/i/maps/111206-100504_GGI_Plan.jpg). This drilling was designed to infill the deposit at 50 metre spacing and also to expand the mineralized zone along strike. These latest results have extended the Goulagou I deposit a further 150 metres to the west, and the deposit remains open along strike in both directions and at depth. Mineralization has been extended to a distance in excess of 2,100 metres on this deposit and the width of the mineralized zone varies from 50 metres at the east end up to 300 metres in the west.

Significant assay intervals are as follows:

  • 1.33 g/t Au over 52 m, including 2.38 g/t Au over 12 m, in RC-254
  • 1.10 g/t Au over 16 m in RC-252
  • 1.05 g/t Au over 12 m, 2.37 g/t Au over 6 m and 1.39 g/t Au over 10 m in RC-234
  • 1.55 g/t Au over 10 m and 0.79 g/t Au over 18 m in RC-237
  • 1.40 g/t Au over 8 m in RC-244

"We are impressed to see higher grade gold mineralization that extends the overall strike length of the Goulagou I deposit which continues to be expanded and it is still open along strike," commented Dwayne Melrose, President of Riverstone. "Riverstone is systematically expanding and defining the deposit for the upcoming future resource estimation."

Significant results are presented in the following table:

Note: Drill holes RC-238, RC-239, RC-240, RC-241, RC-245, RC-246, RC-248, RC-249 and 253 reported either low grade values or no significant results. Interpreted true widths for RC-234 to RC-237, RC-250 and RC-251 are between 90 and 100 percent, for RC-252 and RC-254 are between 70 and 80 percent, and for RC-242 and RC-247 are uncertain but probably between 50 and 60 percent.

The Goulagou I deposit is part of the Karma Project which comprises six contiguous permits. The Company has a 100% interest in two of the permits and has an option to acquire an indirect 90% interest in the remaining four permits. The Karma Project has 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 in excess of an additional 40,000 metres at Karma, and it is expected that the results of this drilling will add to the resource. 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 RC 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 1,452 square kilometres.
