Riverstone Resumes Drilling at Kao Main Gold Zone

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 29, 2008) - Riverstone Resources Inc. (TSX VENTURE:RVS)(FRANKFURT:3RV) is pleased to report that a fourth phase of reverse circulation ("RC") drilling has commenced on its Kao Exploration Permit in Burkina Faso, West Africa. The program will comprise approximately 5,000 metres of drilling in 50 holes. The drilling will target the promising Kao Main zone, which was expanded to 600 metres in length by approximately 300 metres in width during the last drill program in October of 2007. The zone remains open for expansion in several directions. The objective of this phase of drilling is to define the limits of the mineralization so that a resource estimation can commence. Although the majority of the planned drilling will be carried out on the Main Zone, a number of other promising targets on the property will also be drill tested.

The Kao Main Zone is one of three significant gold deposits known to exist on four contiguous exploration permits held by the company. The other two gold deposits are Rambo and Goulagou. The most advanced is the Goulagou deposit where previous work has identified a NI 43-101 compliant indicated resource of 280,000 ounces of gold at a grade of 1.70 g/t and a further inferred resource of 270,000 ounces of gold at a grade of 1.49 g/t (see News Release dated October 11, 2007).

These four contiguous permits: Kao, Rambo, Goulagou and Rounga, have been collectively named the Karma project, after a small village on one of the permits. The company is planning aggressive drilling programs on the Kao, Goulagou and Rambo deposits during the first half of 2008. The company has also identified many untested targets within the Karma project area, and several of these will be drill tested during 2008. The Company's strategy is to develop sufficient gold resources within the project area to support a mining operation utilizing a central processing plant. Management of the company believes it is on track to identify a cumulative gold resource in all categories in excess of 1,000,000 ounces of gold in 2008 within the project area.

Previously reported results from the Phase 3 RC drill program (see News Releases dated November 15, December 12, 2007 and December 9, 2007) are shown in the table below. All holes were drilled at -60 degrees. Intervals reported are drilled intercepts, which may not represent true widths of the mineralized zones.

The Company maintains a rigorous quality control program involving the use of repeat assays, inserted blanks, and the use of verifiable standards from an accredited Canadian laboratory. All RC 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 high quality exploration permits.
