Riverstone Announces Update of Gold Mineralization at Karma Project
(firmenpresse) - VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 10/03/12 -- Riverstone Resources Inc. (TSX VENTURE: RVS)(OTCQX: RVREF)(FRANKFURT: 3RV) ("Riverstone" or the "Company") announces an updated independent NI 43-101 compliant Mineral Resource estimate, that shows an increase of 27% for the Indicated in-pit mineral inventory and 23% for the global mineral inventory compared to the January, 2012 resource estimate at its flagship Karma gold project (the "Karma Project") in Burkina Faso, West Africa (See Riverstone's news release dated January 9, 2012). The NI 43-101 compliant resource estimate has been completed by P&E Mining Consultants Inc. ("P&E") of Brampton, ON. The estimate was completed on the Goulagou I, Goulagou II, Kao, Rambo and Nami deposits, which are all in close proximity to each other.
HIGHLIGHTS (resources are contained within five Whittle open pit shells)
"We are very encouraged with the increase of resources at Karma," commented Dwayne L. Melrose, President and CEO of Riverstone Resources Inc. "This will provide a solid base for going forward with engineering and economic studies in 2012/2013 to establish Karma as one of the premier gold projects in West Africa. There also remains significant potential to continue to increase the gold resource with further drilling in the future."
The Karma Project consists of five separate deposits, which are located in close proximity to each other. A summary of the resource estimates within a Whittle pit shell for each deposit is presented in the table below:
The resource estimation is based on a total of 1,220 diamond and reverse circulation drill holes for 183,374 metres. Subsequent to the January 2012 resource estimation, a total of 383 new diamond and reverse circulation holes for 77,641 metres are credited to the resource update.
Riverstone will continue with the on-going drill program to further extend and upgrade the resource quality of the 5 deposits and also to test regional targets throughout the remainder of 2012 and into 2013.
All reported resources fell within the limits of the mineralized wire frames. All interpolated grade blocks or partial blocks within the resource wire frames need to have at least three composites from two holes within 50 metres to be classified as Indicated Resource. Inferred Resources were determined from the remaining blocks, or partial blocks that lie within the wire frames.
Assay data used as a basis in these resource estimates have been independently verified from original assay lab certificates.
The mineral resource estimates in this press release were prepared by Eugene Puritch, P.Eng., Antoine Yassa, P.Geo., and Yungang Wu, P.Geo of P&E, each an independent qualified person, as defined by National Instrument 43-101 ("NI 43-101").
Mr. Puritch has reviewed and approved the contents of this news release. Paul G. Anderson, MSc. P.Geo., the Company's Vice-President of Exploration, is Riverstone's Qualified Person for the purposes of NI 43-101 and has approved the technical content of this news release.
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. The Company's flagship project is the Karma Project. The results of a Preliminary Economic Assessment have recently been released (see Company news release dated August 20, 2012 and NI 43-101 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 SEDAR () September 17, 2012), highlighting the Karma Project to be a robust project.
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, West Africa (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 an ALS Chemex facility in North Vancouver, British Columbia, Canada, or in Johannesburg, South Africa.
