Riverstone Discovers New Gold Zones on Bouboulou

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 7, 2007) - Riverstone Resources Inc. (the "Company") (TSX VENTURE:RVS) is pleased to report results from a surface mapping and sampling program that was recently completed on the Bouboulou Exploration Permit in Burkina Faso, West Africa. The rock samples were collected within a very large gold anomaly defined by a Rotary Air Blast ("RAB") drilling program conducted in the late 1990's by a previous operator. The rock sampling results confirm and better define this gold anomaly, which covers an area 13 kilometres long by 2 to 6 kilometres in width, and lies entirely within the permit.

The gold zone defined by the historic RAB drilling straddles the projected southwesterly extension of the Sabce shear zone. The Sabce shear zone controls the location of numerous artisanal gold mining sites spread over at least 130 kilometres, as well as the Bissa gold deposit, currently being developed by High River Gold. Riverstone controls seven properties, including the Bouboulou permit, which covers the northeast and southwestern limits of the Sabce shear. The RAB drilling program comprised 664 holes totaling 25,400 metres with an average depth of 38 metres. The holes were drilled on a 500 metre by 500 metre grid with some in-fill drilling on a 250 metre grid.

The recent surface samples were collected from quartz veins and mineralized wallrock, and some of the better results are listed below:



---------------------------------- ----------------------------------
GRADE GRADE
TYPE OF SAMPLE (g/t gold) TYPE OF SAMPLE (g/t gold)
---------------------------------- ----------------------------------
Qtz vein 2.97 Qtz vein 8.24
Qtz vein 3.03 Sediment 2.46
Sediment 2.01 Sediment 3.88
Qtz vein 6.76 Qtz vein 4.83
Sediment 1.79 Qtz vein 1.52
Qtz vein 2.44 Qtz vein 1.63
Qtz vein 1.09 Qtz vein 6.67
Qtz vein 1.12 Qtz vein 1.71
Qtz vein 8.46 Qtz vein 7.47
Qtz vein 19.16 Trench Sample 0.56 g/t over 16m
Sediment 1.24 including 2.38 g/t over 2m
Qtz vein 1.46 Trench Sample 0.49 g/t over 6m
---------------------------------- ----------------------------------


Work to date on this permit by the Company indicates that intersecting shear structures may provide favourable sites for gold mineralization. In addition, several distinct zones of more intense quartz veining have been shown to be gold bearing, as evidenced in the table above. This may indicate that higher-grade gold zones exist within the large gold anomaly outlined by the RAB drilling. Work is continuing on this permit, with the objective of establishing drill targets to be tested later in the year.

The Company maintains a rigorous quality control program involving the use of repeat assays, check assays at independent labs, and the use of verifiable blanks and standards from an accredited Canadian lab. All 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.
