Riverstone Continues to Extend Higher Than Average Gold Grade Mineralization at GGI

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 18, 2012) - Riverstone Resources Inc. (TSX VENTURE:RVS)(OTCQX:RVREF)(FRANKFURT:3RV) ("Riverstone" or the "Company") is pleased to report results from nineteen diamond core drill holes on the 90% owned GGI Deposit, which forms part of the Company's flagship Karma gold project in Burkina Faso, West Africa (the "Karma Project").

These holes are part of a program of drilling designed to extend and confirm the deposit to depth, and to collect material for metallurgical testing. (See Map on Website for the location of the holes: http://www.riverstoneresources.com/i/maps/120614-100504_GGI_Plan.jpg).

Significant assay intervals in these core holes are as follows:

• 2.15 g/t Au over 40 m in DD-11-060
• 2.34 g/t Au over 26 m and 1.73 g/t Au over 14 m in DD-11-062
• 2.15 g/t Au over 18 m in DD-11-049
• 1.88 g/t Au over 16 m in DD-11-031
• 1.66 g/t Au over 12 m in DD-11-036
• 1.37 g/t Au over 24 m in DD-11-025
• 1.32 g/t Au over 24 m and 1.40 g/t Au over 16 m in DD-11-033

Mineralization at GGI extends over 2,100 metres east-west and to as much as 200 metres down-dip in areas of deeper drilling. The deposit remains open in both directions along strike, as well as to depth; there is only very limited drilling below 200 metres vertical depth.

"We are very encouraged with these assays from drilling at GGI as the property continues to produce good gold intersections," commented Dwayne L. Melrose, President and CEO of Riverstone. "Not only have we continued to intersect good grade gold mineralization here at GGI but we have also continued to intersect above average grade gold intersections at our GGII (May 29, 2012) and Kao (June 12, 2012) deposits. Riverstone has also completed +85,000 metres of drilling since the cut-off date of the last resource estimation."

Notes: Interpreted true thicknesses for these intercepts are between 60 and 80 percent.

Holes 035 and 048 returned no significant values.

Holes 038 to 045, 047, and 050 to 059 were drilled at the nearby GGII deposit. To read the entire news release follow the link below:
