Riverstone Intersects 14 Metres Averaging 2.44 g/t Gold at the Kao Zone on the Karma Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 5, 2011) - Riverstone Resources Inc. (TSX VENTURE:RVS)(OTCQX:RVREF)(PINKSHEETS:RVREF)(FRANKFURT:3RV) is pleased to report results from a further seven diamond 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 on website: http://www.riverstoneresources.com/i/maps/111202-091112_Kao_Plan.jpg). This drilling is part of a major on-going 90,000 metre Karma Project drill program designed to confirm the results of reverse circulation ("RC") drilling, confirm the continuity of mineralization and also extend the mineralization to depth and along strike.

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

Significant assay intervals are as follows:

  • 1.52 g/t Au over 20 m, including 5.80 g/t Au over 4 m in DD-028
  • 1.06 g/t Au over 38 m, including 1.70 g/t Au over 10 m in DD-030
  • 1.37 g/t Au over 18 m in DD-033
  • 2.44 g/t Au over 14 m in DD-034

"We are happy to see that the diamond drilling of the KOA mineralization is so consistent along strike and down dip, and confirmed and upgraded the RC results," commented M. D. McInnis, CEO of Riverstone. "The design of the drilling program is part of the future plan to complete a Preliminary Economic Study in 2012."

Significant results are presented in the following table:

Hole number Interval (m) Intercept Average
From To (metres) Grade (g/t Au)
KAO-DD-11-028 80 100 20 1.52
including 80 84 4 5.80

and 80 90 10 0.50
and 98 108 10 0.56

Note: Interpreted true thicknesses for these holes are between 95 and 100 percent.

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 six high quality exploration projects covering 2,300 square kilometres.
