Rio Novo Gold Inc. Announces 30 Year Concession Contract Award at Toldafria

TORONTO, Sept. 6, 2011 - Rio Novo Gold Inc. (TSX: RN) (TSX: RN.WT) ("Rio Novo" or the "Company") is pleased to announce that the Permit Holder, Nestor Gutierrez has successfully converted the Toldafria 10 year mining license into an Ingeominas (the Colombian Institute of Geology & Mining) registered 30 year Concession Contract, a key 2011 goal of the Company. Rio Novo is working expeditiously with the Permit Holder to finalize the process that will transfer 100% of the Concession Contract to Rio Novo.

As expressed at the time of the acquisition (June 1, 2011), Rio Novo policy determines that strict adherence to local procedures and respect for local processes is a key to successful permitting of mining projects in any country and Colombia is no different in this respect.

David Beatty, Chief Executive Officer of Rio Novo said "this key development came within 75 days of our agreement to option the Toldafria property and substantially enhances its value to Rio Novo. The successful conversion to the Concession Contract advances our overall objectives in Colombia".

The Company now intends to move forward on initial base line environmental studies and an environmental management plan and is fully committed to improving environmental standards in the area as a matter of Corporate Policy. Concurrently, Rio Novo will be implementing additional tunnel sampling and preparing for future exploration efforts such as trenching, drilling and comprehensive analysis efforts.

Exploration efforts to date have been focused on channel sampling of existing underground workings. To date, approximately 15% of the total land package area has been sampled. Over the next few months Rio Novo will extend underground channel sampling to the north and south to further delineate the size of the system.

Rock chip samples have been taken in a first pass reconnaissance program covering the northern portion of the project area. The sampling has identified a number of surface anomalies outside of the known area of mineralization (please see figure on the following link: http://media3.marketwire.com/docs/rn_f1.pdf).

Rio Novo is currently following up with mapping and additional surface sampling to further define these anomalies. A trenching program is planned to better understand the structure and gold distribution of the system.

Although the property has been worked by small-scale artisanal miners, there is no drilling on the property at present. Rio Novo is currently in the planning stage for a first pass of surface and underground drilling. This drilling is planned to commence in first quarter of 2012 after receipt of permits.

Finally, the Company is evaluating potential further acquisitions in the region and in Colombia.
