Riverstone Intersects 52 m Averaging 1.78 g/t Gold at Kao Deposit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 26, 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 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 an overall program of drilling designed to expand the gold mineralization in all dimensions and to upgrade the resource quality of the central portion of the deposit (see Map on the Riverstone Website for the location of holes: http://www.riverstoneresources.com/i/maps/120622NR-091112_Kao_Plan.jpg).

Significant assay intervals in these core holes include:

  • 1.78 g/t Au over 52 m and 2.20 g/t over 12 m in DD-12-092
  • 2.08 g/t Au over 38 m in DD-12-088
  • 2.13 g/t Au over 32 m in DD-12-089
  • 2.27 g/t Au over 20 m including 4.04 g/t over 8 m in DD-11-071
  • 2.51 g/t Au over 10 m in DD-12-103
  • 2.10 g/t Au over 22 m in DD-12-093
  • 2.97 g/t Au over 8 m in DD-12-085

"The Kao deposit continues to expand in size as the deposit remains open in both strike directions and down-dip," commented Dwayne L. Melrose, President and CEO of Riverstone. "We have not found the limits of the Kao deposit to date and we have consistently continued to intersect gold results which are twice the average grade of the overall deposit."

Mineralization at Kao now extends over 1,100 metres north-south and at least 900 metres down-dip to the east. These results indicate that the deposit remains open to the north and south, as well as down-dip. The holes detailed in this release were designed to extend the down-dip gold mineralization to the east and to upgrade the higher grade gold zone in the central part of the deposit (an interpretive cross-section on the Website shows the geometry of the east-ward dipping mineralized body: http://www.riverstoneresources.com/i/maps/120622NR-120621-KaoXS1497925N.jpg).

Since the data cut-off point for the previous resource estimation (released January 9, 2012), the Company has completed +85,000 metres of drilling on the Karma Project, including approximately 54,000 metres of drilling which have been completed at the Kao deposit. It is expected that the results of this drilling will add to the overall resources of the Karma Project deposits.

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).

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 samples were prepared at the independent Abilab Burkina SARL laboratory in Ouagadougou, Burkina Faso (part of the ALS Chemex Group), 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, either in Burkina Faso or at the ALS Chemex facility in North Vancouver.

Further to the Company's news release of January 13, 2012, the Company is pleased to announce that it has now repaid in full the $5 million secured credit facility, which it received from Sprott Resource Lending Partnership.

Further to the Company's news release of April 4, 2012, the Company is also pleased to announce that with the expiry of the applicable lock-up period thereon, it has completed the sale of its remaining 11,500,000 common shares of Roxgold Inc. through the facilities of the TSX Venture Exchange, receiving gross proceeds of approximately $8.14 million.

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.
