VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 19, 2012) - Riverstone Resources Inc. (News - Market indicators) (OTCQX:RVREF)(FRANKFURT:3RV) ("Riverstone" or the "Company") is pleased to announce that Senet (Pty) Ltd. ("SENET") of Johannesburg, South Africa has been engaged to conduct the independent definitive Feasibility Study for the Company's flagship Karma Gold Project (the "Karma Project") in Burkina Faso, West Africa. The Feasibility Study will entail development of a comprehensive operating plan and cost estimate for a 3 to 4 million tonne per annum ("Mtpa") open pit, heap leach gold mine similar to that described in the independent Preliminary Economic Assessment ("PEA") (see Riverstone news release dated August 20, 2012 and in dependent NI 43-101 compliant technical report titled, "Preliminary Economic Assessment Report for the Karma Project, Burkina Faso, West Africa", with an effective date of August 2, 2012, filed on www.sedar.com ("SEDAR") September 17, 2012) on the Karma Project. The Feasibility Study will be based on a total indicated, in-pit, resource of free-leaching material containing 1.03 million ounces of gold (see Riverstone news release dated October 3, 2012, and independent NI 43-101 compliant technical report titled, "Technical Report and Updated Resource Estimate on the Karma Project, Burkina Faso, West Africa", dated effective October 1, 2012, filed on SEDAR November 7, 2012) and will focus on mining and processing of the free-leaching portions of the deposit only. The Feasibility Study is scheduled to commence November 2012 and is expected to be completed in mid-2013.
SENET has a wealth of experience engineering and building mining projects in Africa. They have demonstrated expertise in heap leach and were engaged in the construction of the Kalsaka Mine, a 1.6 Mtpa heap leach operation located in Burkina Faso, 50 km south of the Karma Project site. SENET proposes to subcontract the mining and heap leach pad and hydrology design portions of the Feasibility Study to SRK Consulting and Knight-Piesold (Pty) Ltd., respectively, also of South Africa.
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 km. Riverstone's flagship project is the Karma Project, which as reported in the PEA, comprises a NI 43-101 compliant in-pit Whittle total indicated resources of approximately 1.9 million ounces of gold in 56.5 million tonnes with an average grade of 1.07 g/t gold and total inferred resources of approximately 492 thousand ounces of gold in 15.4 million tonnes with an average grade of 1.0 g/t gold. The results of the PEA, which highlights the Karma Project to have robust economics, is based on Riverstone's previous January 9, 2012 resource estimate and while relevant and valid in regards of the January 9, 2012 estimate cannot necessarily be extrapolated to the updated resource estimate announced on October 3, 2012.
The PEA is considered preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves and there is no certainty that the production profile concluded in the PEA will be realized. Mineral Resources that are not Mineral Reserves have not yet demonstrated economic viability.
