Riverstone Continues to Expand the Goulagou Gold Deposits on its Karma Project

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 07/20/10 -- Riverstone Resources Inc. (TSX VENTURE: RVS)(FRANKFURT: 3RV) is pleased to report more positive results from the drill program at its Goulagou gold deposits in Burkina Faso, West Africa (See Map on Website: http://www.riverstoneresources.com/i/maps/100719_GGI_Plan.jpg). The goal of the continuing drill program is to upgrade and expand the current resource at the Goulagou deposits, as well as the other two deposits that comprise the Company's Karma gold project.

'These latest results from the Goulagou I deposit extend the mineralization significantly to the east,' said M.D. McInnis, President & CEO of Riverstone. 'We continue to be very encouraged by the expansion potential of this deposit.'

The Goulagou deposits are part of the Company's Karma project which, in addition to the Goulagou deposits, comprises the Rambo, Kao and the promising new Nami site. Since March 2010, the Company has drilled over 15,000 metres of RC drilling and over 2,000 metres of diamond drilling, in addition to over 7,000 metres of RAB drilling at Nami. A large number of drill samples are currently still in the analytical laboratory with results expected to be reported over the next few weeks.

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 rock samples were assayed using standard fire assay with atomic absorption techniques, with samples grading over two grams 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 permits covering 2,300 square kilometres.
