Riverstone Completes Sale of Remaining Interest in Yaramoko, Solna and Bissa West Projects; Acquires 19% Interest in Roxgold Inc.

VANCOUVER, 10/26/11 -- Riverstone Resources Inc. (TSX VENTURE: RVS) (OTCQX: RVREF) (FRANKFURT: 3RV) ('Riverstone' or the 'Company') is pleased to announce the closing of the sale of its remaining interests in the Yaramoko, Bissa West and Solna projects in Burkina Faso, West Africa to Roxgold Inc. ('Roxgold').

Riverstone received consideration having an aggregate value of approximately $36 million, comprising $17 million in cash and 16 million Roxgold common shares having a value of approximately $19 million based on the closing price of Roxgold common shares on October 25, 2011. Riverstone now owns 16,980,000 Roxgold shares representing approximately 19% of the issued and outstanding voting securities of Roxgold, on a non-diluted basis. Additional details of the transaction and the consideration are contained in the Company's news release dated September 21, 2011.

'This is an excellent deal for both companies,' commented M.D. McInnis, Chairman and CEO of Riverstone. 'We have monetized our direct interest in the properties, but will participate in the value creation potential through our 19% equity interest in Roxgold. We look forward to working with Roxgold to unlock that potential.'

Dwayne L. Melrose, President and COO of Riverstone commented, 'The $17 million cash portion received by Riverstone places us in a strong financial position to continue to advance our West African strategy with an immediate focus on growing and developing our flagship Karma asset. We have five drill rigs under contract and we plan to aggressively move Karma forward on a development path.'

Riverstone is active in gold exploration in Burkina Faso, West Africa. The Company's most advanced project is Karma, which comprises a NI 43-101 compliant gold resource of 810,600 ounces of gold in 22,845,000 tonnes grading 1.10 g/t gold in the indicated category and 1,119,100 ounces of gold in 44,100,000 tonnes grading 0.79 g/t gold in the inferred category. (See news release dated February 28, 2011). Since the resource was calculated in February 2011, the Company has drilled in excess of 40,000 additional metres, and it is expected that the result of this drilling will add significantly to the resource.
