Riverstone Plans 15,000 Metres of RAB Drilling on Burkina Properties

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - June 6, 2006) -


Riverstone Resources Inc. (the "Company") (TSX VENTURE:RVS) is pleased to report that the summer work program on the Company's gold projects in Burkina Faso, West Africa has commenced. The Company has planned an integrated program of geological mapping, geochemical rock and soil sampling and 15,000 metres of RAB drilling on three of its properties as described below. The Phase I program is budgeted at CDN$1.3 Million and will be completed by the end of August. Phase II follow-up work on these properties and the Company's other permits will be carried out during the period September to December.


The Ligidi property is located about 125 kilometres southeast of the capital city of Ouagadougou. Geochemical soil sampling in 2004 established an extensive area anomalous in gold approximately 13 kilometres long and 3 kilometres wide. Within this broad area, numerous linear anomalous zones, each between 1 and 2 kilometres in length, were subsequently delineated. Three broad areas were designated - the Three Hills area, the Wayalguin area and the Dassoui area. Trenching and eight RC holes were completed within the Three Hills and Wayalguin areas only. At Three Hills, trench LM-TR-04 returned 111 metres grading 0.63 grams/tonne gold (g/t), including two intervals of 1.52 g/t over 18 metres and 1.43 g/t over 17.5 metres. RC Hole LM-05-05, which undercut the trench, returned 16.5 metres grading 1.245 g/t gold.

The 2006 program at Ligidi consists of extensive rock sampling within the areas of the geochemical soil anomalies followed by 5,000 metres of RAB drilling. The sampling is underway and the RAB drilling is scheduled to commence by June 15.


The Company holds six permits in the active Bissa area located in north-central Burkina Faso. The Company's permits are adjacent to High River Gold Mines Ltd Bissa project. High River recently announced an independent resource estimate for the Bissa project of 81,980 ounces of gold in the measured category, 580,270 ounces in the indicated category and 679,470 ounces in the inferred category.

The Bissa deposit is located within the Sabce Shear Zone which extends northeasterly from High River's property onto Riverstone's Tangapella permit. The Bissa deposit is approximately 6 kilometres from the boundary of the Tangapella permit. The Sebila permit is also located on the eastern boundary of High River's property and overlies a 15 kilometre portion of a shear zone which parallels the Sabce Shear Zone.

The Tangapella permit in particular appears to be highly prospective. The permit is transected by about 20 kilometres of the Sabce Shear Zone. Geochemical soil anomalies discovered by previous operators suggest the presence of gold mineralization and structural folds provide excellent sites for gold emplacement.

A geochemical soil-sampling program covering a grid measuring 10 kilometres in length and 7 kilometres in width is currently underway on the Tangapella permit. A follow-up RAB drilling program comprising approximately 5,000 metres is scheduled to commence around August 1.


The Tao permit adjoins the Essakane project on its southern boundary. The Essakane project is a joint venture between Orezone Resources Inc. and Gold Fields Limited. Orezone recently announced that Gold Fields has approved a US$9.3 million budget to complete a pre-feasibility study.

Geochemical soil sampling on the TAO permit by a previous operator outlined several large gold anomalies that aggregate greater than 10 kilometres in length. Trenching and RC drilling completed by a former operator on one of the geochemical anomalies outlined a mineralized zone approximately one kilometre in length. Nine RC Holes were drilled and returned grades ranging from 0.949 g/t gold to 4.982 g/t over widths ranging from 1.5 metres to 13.5 metres.

Riverstone staff is compiling all of the previous data and will be initiating a 5,000 metre RAB drilling program commencing around mid-July.

Riverstone has 6 project areas comprising 12 permits in Burkina Faso, which it has been actively exploring for the past three years.
