Riverstone Intersects 4.06 g/t Gold Over 22 Metres at GGII
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 07/09/12 -- Riverstone Resources Inc. (TSX VENTURE: RVS)(OTCQX: RVREF)(FRANKFURT: 3RV) ("Riverstone" or the "Company") is pleased to report results from seven diamond core drill holes on the 90% owned Goulagou II Deposit (the "GGII"), which forms part of the Company's flagship Karma Gold Project in Burkina Faso, West Africa (the "Karma Project"). These holes are part of a program of drilling designed to extend two high-grade "shoots" of mineralization along strike and to depth. (See Map on the Riverstone Website for the location of the holes: http://www.riverstoneresources.com/i/maps/GGIIlocationmap_July5.jpg).
Significant assay intervals in these core holes include:
-- 2.83 g/t Au over 84 m including 4.06 g/t over 22 m and including 3.82
over 28 m in DD-12-077
-- 3.97 g/t Au over 20 m and 7.18 g/t over 4 m in DD-12-073
-- 2.41 g/t Au over 40 m and 2.83 over 10 m in DD-12-058
-- 2.78 g/t Au over 20 m and 1.65 g/t Au over 18 m in DD-12-080
-- 2.41 g/t Au over 46.75 m including 3.43 g/t over 24.75 m in DD-12-081
Mineralization at GGII extends over 2,500 metres east-west and to as much as 250 metres in depth in localized areas of deeper drilling. These drill holes have extended the high grade mineralization from previously drilled holes down dip from 40 to 140 metres and along strike from 50 to 100 metres. These high grade mineralized shoots are open along strike in both directions and to depth as is the entire deposit. Previously drilled holes in these high grade mineralized shoots returned several good grade intersections, including 4.3 g/t Au over 41 m, 3.6 g/t Au over 18 m, and 2.45 g/t Au over 26 m. These holes are listed in the NI 43-101 Technical Report titled "Technical Report and Resource Estimate on the Karma Project, Burkina Faso, West Africa" filed on SEDAR (www.sedar.com) February 23, 2012.
"We are very encouraged with these assays from drilling at GGII as the property consistently continues to intersect high grade gold intersections," commented Dwayne L. Melrose, President and CEO of Riverstone. "We are continuing to expand the size of these higher grade gold mineralized shoots which will be included in the upcoming resource estimate schedule for September 2012. The Preliminary Economic Assessment that is currently being conducted is progressing on schedule and is expected to be released in August 2012."

The 90% owned GGII deposit is part of the Company's Karma Project which comprises a NI 43-101 compliant in-pit Whittle indicated resource of 1.6 million ounces of gold in 47.3 million tonnes grading 1.1 g/t gold and an inferred resource of 0.6 million ounces of gold in 18.9 million tonnes grading 0.93 g/t gold (see news release dated January 9. 2012 and NI 43-101 Technical Report titled "Technical Report and Resource Estimate on the Karma Project, Burkina Faso, West Africa" filed on SEDAR (www.sedar.com) February 23, 2012.) Since the data cut-off for the resource estimation, the Company has already completed +85,000 metres of drilling on the Karma Project. It is expected that the results of this drilling will add to the overall resources of the Karma Project deposits.
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, (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 the ALS Chemex facility in North Vancouver, British Columbia, Canada.
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.
