Riverstone Intersects 26 Metres Averaging 1.34 g/t Gold at the Kao Zone on the Karma Project

Riverstone Resources Inc. (TSX-V: RVS) is pleased to report additional results from 9 diamond drill holes from the on-going diamond drill program on the Kao Zone, which forms part of the company’s flagship Karma Gold deposit in Burkina Faso, West Africa. (See Maps on Website: http://www.riverstoneresources.com/i/pdf/2011-10-28_NRM.pdf). The diamond drilling program on Kao is designed to test and upgrade known mineralized zones and to explore down dip and to the east from the existing resource. These results confirm the existing mineralization and also extend the mineralized zones up to 150 metres along strike to the east and down dip beyond the existing resource. The deposit remains open along strike to the east and down dip. It is significant that all of the 9 holes have intersected potentially economic grades and widths. Drilling is currently in progress to further confirm and extend the known mineralization.

Significant assay intervals are as follows:

•1.34 g/t Au over 26.0 metres
•1.11 g/t Au over 28.0 metres including 1.59 g/t Au over 14.0 metres
•1.7 g/t Au over 8.0 metres
•1.29 g/t Au over 10.0 metres and 2.18 g/t Au over 8.0 metres
•1.51 g/t Au over 8.0 metres

“These results continue to be very encouraging and exciting to the overall project.” commented M.D. McInnis, CEO of Riverstone. “Kao is a shallow dipping zone and we are confirming and extending the presence of good grade gold mineralization along strike and down dip from the existing known resource. We expect that a substantial increase in the potential open pittable resource can be achieved by drilling that is planned to increase the overall resource.”


The 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 37,000 metres, and it is expected that the results of this drilling will add to the 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.
