Riverstone Doubles Size of Main Gold Zone at Kao

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 9, 2008) - Riverstone Resources Inc. (the "Company") (TSX VENTURE:RVS)(FRANKFURT:3RV) is pleased to report final results from the Phase 3 drill program recently completed on its Kao Exploration Permit in Burkina Faso, West Africa. The Phase 3 reverse circulation ("RC") drilling has doubled the size of the large, near surface gold-bearing system that was discovered in the Phase 1 drilling program. The Kao Main zone is now 600 metres long, averages approximately 300 metres in width and is open for expansion in several directions.

M.D. McInnis, President of Riverstone commented, "We are extremely pleased with the results of Phase 3 drilling. We are delineating a substantial gold zone, which will add to the known gold resource on our adjacent Goulagou property. We are confident that further work in 2008 on the Kao, Goulagou and contiguous Rambo permits will result in a cumulative gold resource in all categories in excess of 1,000,000 ounces of gold."

New results include a 28 metre thick intersection of 1.42 grams per tonne (g/t) gold in Hole 092, including 10 metres of 2.78 g/t gold. Additional selected gold intercepts include 10 metres of 1.62 g/t gold and 18 metres of 1.15 g/t gold in Hole 094, as shown in the table of results below and on the attached sketch.

The Kao permit is contiguous with the Company's Rambo and Goulagou permits. The Goulagou permit is held by the Company under an option to purchase, and 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).

The Phase 3 drill program at Kao comprised 5,703 metres in 57 drill holes. Previously reported results (see News Releases dated November 15 and December 12, 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 Phase 3 drill program was designed to extend and infill drill a 300 metre by 300 metre portion of the permit area now called the Kao Main Zone, which had been identified in previous RC drill programs in 2007. The main axis of the Kao Main Zone is now 600 metres long, and it remains open in several directions, particularly to the north and northwest. It is also open below 85 metres vertical depth. In addition, a separate gold zone appears to be developing in the vicinity of Hole 008, which assayed 21.46 g/t gold over 2 metres within a much wider lower grade gold zone. There is a strong possibility that other gold zones can be developed on the property, as the Kao Main Zone lies within a strong, 4 kilometre long gold-in-soils anomaly that is virtually untested.

The Company maintains a rigorous quality control program involving the use of repeat assays, check assays at independent labs, 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.
