The holes reported in this release are all from the Bagassi Central target in an area referred to as the '55 Zone'. The 55 Zone has been tested over a strike length of 300 metres with holes drilled on 25 metre fences. Assays are pending for an additional 9 holes drilled in the 55 Zone. The zone is open on strike and to depth. A second zone, the 35 Zone, is located 175 metres to the west of the 55 Zone and has been tested with 10 drill holes. Assays are pending for this zone.

In July 2010, Riverstone entered into an option agreement with Roxgold Inc. whereby Roxgold could earn a 60% interest in the Yaramoko property by incurring exploration expenditures of $1.5 million and issuing a total of 360,000 Roxgold shares and a total of $100,000 to Riverstone over the three year term of the agreement (see news release dated July 13, 2010). On September 21st, 2011, Riverstone Resources and Roxgold entered into a binding letter agreement pursuant to which Roxgold has agreed to acquire the remaining interests in each of the Yaramoko, Bissa West and Solna projects from Riverstone (See news release dated September 21st). Under the terms of the agreement, Riverstone will receive total consideration of approximately $33.5 million, comprising $17 million in cash and 16 million Roxgold common shares valued at $1.03 per common share (based on the closing share price of Roxgold common shares on September 20, 2011). Upon closing of this transaction, Riverstone will own approximately 17.0 million Roxgold common shares, representing 19.3% of Roxgold's outstanding shares.

Riverstone Resources Inc. is active in gold exploration in Burkina Faso, West Africa, where the company holds an extensive portfolio of six high quality exploration projects covering 2,300 square kilometres. 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 to the resource.


QUALITY ASSURANCE/QUALITY CONTROL

Roxgold is the operator of this drill program and maintains a quality control program involving the use of repeat assays, inserted blanks and the use of certified standards from an accredited Canadian laboratory. In order to avoid delays associated with assaying facilities in Burkina Faso, all Yaramoko assays reported in this press release were assayed at TSL Laboratories in Saskatoon, Saskatchewan using metallic screening techniques with duplicate assays performed on every fortieth sample. These samples were selected based on the presence of visible gold and/or increased silicification and sampled at one metre intervals. The remainder of each drill hole has been sampled on two metre interval and samples grading over one gram gold per tonne in initial fire assay/atomic absorption assays will be re-assayed with a gravimetric finish, at the independent Abilab Burkina SARL laboratories in Ouagadougou, Burkina Faso, which is part of the ALS Chemex group. A high level of exploration and development activity in the gold sector in Burkina Faso has resulted in an increase in the turnaround time for receiving all gold assays.
