Riverstone Defines Large Open Footprint for the Nami Gold Discovery

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 16, 2010) - Riverstone Resources Inc. (TSX VENTURE:RVS)(FRANKFURT:3RV) is pleased to announce the results from the sampling of the waste dumps at the Nami artisanal site in Burkina Faso, West Africa. The waste dumps comprise material left behind by the artisanal miners after high grading the quartz veins, and they are considered by them to carry no gold grade. The size of the mineralized footprint, as defined by the 0.3 gpt contour, is 500 metres by 300 metres. The zone is open for extension to the northwest, southwest and southeast. The average of all samples greater than 0.3 g/t is 1.36 g/t with a high of 8.6 g/t (Link to map: http://www.riverstoneresources.com/i/maps/Rambo_NASDS.jpg).

"We are very pleased with the results from the waste dump sampling," commented M.D. McInnis, President and CEO of RVS. "We knew from our sampling of the quartz veins and quartz breccias that they carry exceptionally high values of gold but we had very little information on the gold content of the host rock surrounding the quartz bearing material. The average grade of 1.36 g/t returned from the waste dump material certainly exceeded our expectations and is a very positive development for the project."

The Nami artisanal site is part of the Company's Karma gold project. The site comprises several hundred 1 metre by 1 metre vertical shafts that have been dug by the artisinal miners to depths of up to 60 metres. Quartz bearing material from the shafts is separated by hand by the miners and the waste rock is piled adjacent to the shafts. Previous sampling by the Company of the quartz bearing rock returned numerous values in excess of 10 g/t gold with a high of 98 g/t. (See News Release dated Jan. 18 and Feb 23, 2010). These high grade values should elevate the average grade of the Nami site to a value well in excess of the 1.36 g/t background value defined by the dump sampling.

Sampling of the waste dumps was carried out by establishing a 25 metre by 25 metre grid over the entire artisanal site. At each sample site a 10 to 13 kg sample was collected randomly from the waste dumps nearest the sample site.

The Company maintains a rigorous 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 in excess of 2.00 g/t gold 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.
