VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 11, 2011) - Riverstone Resources Inc. (News - Market indicators)(OTCQX:RVREF)(FRANKFURT:3RV) has received further results from the drill program on the Company's Karma Project in Burkina Faso, West Africa (see map on website: www.riverstoneresources.com/i/maps/110706v2-100504_GGI.jpg). The ten holes are part of an on-going RC drill program on the Goulagou I zone. The program is designed to both fill-in and expand the known mineralization at Goulagou I, which remains open in all directions, especially to the west and at depth. Highlights include:

• 12.0 metres grading 1.65 g/t Au in Hole 200;

• 36.0 metres grading 1.05 g/t Au in Hole 201; and

• 36.0 metres grading 1.14 g/t Au in Hole 202.

"We are very pleased with the results we have been receiving from the drill program at Goulagou I," commented M.D. McInnis, President and CEO of Riverstone. "The deposit continues to expand in size and new mineralization is being discovered as the drilling progresses."

Results have been received from Holes 192 to 202. Significant intervals are reported in the table below:

"True thicknesses" are not known with certainty, but are estimated to be about 70% of drilled lengths.

The Goulagou I zone is part of the Company's Karma deposit which hosts a NI 43-101 compliant gold resource of 810,000 ounces of gold in 22,845,000 tonnes grading 1.10 g/t gold in the indicated category and 1,119,100 ounces in 44,100,000 tonnes grading 0.79 g/t gold in the inferred category (see news release dated February 28, 2011). 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.
