Riverstone Continues to Extend and Intercept Higher Grade Gold Results at Kao

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 12, 2012) - Riverstone Resources Inc. (TSX VENTURE:RVS)(OTCQX:RVREF)(FRANKFURT:3RV) ("Riverstone" or the "Company") is pleased to report results from fifteen diamond core drill holes on the 100% owned Kao 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 confirm and extend the deposit to depth, upgrade the resource category and to collect material for metallurgical testing. (See Map on Website for the location of the holes: http://www.riverstoneresources.com/i/maps/120611-091112_Kao_Plan_MAP-lg.jpg).

Significant assay intervals in these core holes are as follows:

  • 2.58 g/t Au over 14 m in DD-11-060
  • 2.10 g/t Au over 16 m in DD-11-059
  • 2.03 g/t Au over 14 m in DD-11-064
  • 1.62 g/t Au over 16 m in DD-11-055
  • 1.60 g/t Au over 10 m, 1.42 g/t Au over 14 m and 1.20 g/t Au over 18 m in DD-11-066

Mineralization at Kao extends over 1,100 metres north-south and at least 900 metres down-dip to the east. The deposit remains open to north and south, as well as down-dip.

"We are pleased with these above average grade assays from core drilling at Kao," commented Dwayne L. Melrose, President and CEO of Riverstone. "These results show that our drilling has been successful in extending the strike and vertical extent of the deposit, which could allow for up-grading of the next resource model."

A more complete summary of significant results in these drill holes is presented in the following table:

The 100% owned Kao deposit is part of the Company's Karma Project which comprises a NI 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 gold and an inferred resource of 0.6 million ounces of gold in 18.9 million tonnes grading 0.93 g/t gold (see news release dated January 9, 2012 and NI 43-101 Technical Report titled "Technical Report and Resource Estimate on the Karma Project, Burkina Faso, West Africa" filed on Sedar (www.sedar.com) February 23, 2012.) Since the data cut-off for the resource estimation, the Company has completed in excess of an additional +80,000 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 the use of 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 gram per tonne gold re-assayed with a gravimetric finish, at the independent Abilab Burkina SARL laboratory in Ouagadougou, Burkina Faso, which is part of the ALS Chemex Group.

Riverstone is active in Burkina Faso, West Africa, where it holds a portfolio of four high quality exploration projects covering in excess of 2,000 square kilometres.
