RIVERSTONE CONTINUES TO EXTEND HIGHER THAN AVERAGE GOLD GRADE MINERALIZATION AT GGI

Riverstone Resources Inc. has released results from 19 diamond core drill holes on the 90-per-cent-owned GGI deposit, which forms part of the company's flagship Karma gold project in Burkina Faso, West Africa. 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).

Significant assay intervals in these core holes are as follows:

• 2.15 grams per tonne gold over 40 metres in DD-11-060;
• 2.34 g/t Au over 26 metres and 1.73 g/t Au over 14 metres in DD-11-062;
• 2.15 g/t Au over 18 metres in DD-11-049;
• 1.88 g/t Au over 16 metres in DD-11-031;
• 1.66 g/t Au over 12 metres in DD-11-036;
• 1.37 g/t Au over 24 metres in DD-11-025;
• 1.32 g/t Au over 24 metres and 1.4 g/t Au over 16 metres in DD-11-033.

Mineralization at GGI extends over 2,100 metres east-west and to as much as 200 metres downdip 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 chief executive officer 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 plus metres of drilling since the cut-off date of the last resource estimation."

A more complete summary of significant results in these drill holes is presented in the accompanying table.

Notes: 
Interpreted true thicknesses for these intercepts are between 60 and 
80 per cent.                                                                 
Holes 035 and 048 returned no significant values.                           
Holes 038 to 045, 047 and 050 to 059 were drilled at the nearby GGII       
deposit.                                                  

The 90-per-cent-owned GGI deposit is part of the company's Karma project, which comprises a National Instrument 43-101-compliant in-pit Whittle indicated resource of 1.6 million ounces of gold in 47.3 million tonnes grading 1.1 g/t Au and an inferred resource of 600,000 ounces of gold in 18.9 million tonnes grading 0.93 g/t Au (see news release dated Jan. 9, 2012, and National Instrument 43-101 technical report entitled "Technical Report and Resource Estimate on the Karma Project, Burkina Faso, West Africa," filed on SEDAR Feb. 23, 2012). Since the data cut-off for the resource estimation, the company has completed in excess of an additional 85,000 plus metres of drilling on the Karma project, and it is expected that the results of this drilling will add to the overall resource of the Karma project deposits.

Riverstone maintains a quality control program involving the use of repeat assays, inserted blanks and certified standards from an accredited Canadian laboratory. All core samples were prepared and assayed using standard fire assay with an atomic absorption finish, with samples grading over one g/t Au reassayed with a gravimetric finish at the independent Abilab Burkina SARL laboratory in Ouagadougou, Burkina Faso, which is part of the ALS Chemex Group.
