Riverstone Confirms and Extends Higher Grade Zone at the Kao Deposit
(firmenpresse) - Riverstone Confirms and Extends Higher Grade Zone at the Kao Deposit
March 14, 2012 Symbols: TSXV – RVS; Frankfurt – 3RV; OTCQX - RVREF
Riverstone Resources Inc. (TSX-V; RVS) (“Riverstone” or the “Company”) is pleased to report results from seven diamond drill holes on the 100% owned Kao Deposit, which forms part of the Company’s flagship Karma Project in Burkina Faso, West Africa. These holes are part of a program of core drilling designed to confirm and extend the higher grade zone in the middle of the deposit and upgrade the inferred resources to the indicated category (See Map on Website for the location of the holes).
Significant assay intervals in these core holes are as follows:
•2.93 g/t Au over 16 m in DD-035
•2.19 g/t Au over 10 m in DD-036
•7.31 g/t Au over 2 m, 1.39 g/t Au over 20 m and 1.51 g/t Au over 6 m in DD-037
•1.51 g/t Au over 14 m in DD-038
•1.06 g/t Au over 20 m including 2.06 g/t Au over 8 m in DD-040
•2.13 g/t Au over 10 m in DD-041
•1.26 g/t Au over 26 m including 1.68 g/t Au over 12 m in DD-042
Mineralization at the Kao Deposit has now been extended to over 900 metres north-south and over 900 metres down-dip to the east. The deposit remains open down-dip as well as to the north-east, west and to the south. Several satellite zones remain to be drill tested; drilling continues at the Kao Deposit, with one RC and two core rigs active.
“We are pleased with these assays from core drilling at the Kao Deposit”, commented Dwayne L. Melrose, President and COO of Riverstone. “The results from these two sections near the centre of the Kao Deposit, which hosts the higher grade portion of the deposit, have confirmed the results of previous RC drilling with higher than average grade gold intersections, which will allow for up-grading of the resource model and extends the higher grade mineralization down dip by an additional 50 metres.”
A more complete summary of significant results is presented in the following table:

The 100% owned Kao Deposit is part of the Company’s Karma Project which comprises a NI 43-101 compliant in-pit Whittle gold indicated gold resource of 1.6 million ounces of gold in 47.3 million tonnes grading 1.1 g/t gold and an inferred gold 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 completed an additional +43,000 metres of drilling on the Karma Project, and it is expected that the results of this drilling will add to the overall resource of the five 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 core samples were assayed using standard fire assay with atomic absorption techniques, with samples grading over one gram gold per tonne 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.
Riverstone is active in gold exploration in Burkina Faso, West Africa, where it holds a portfolio of four high quality exploration projects covering +2,000 square kilometres.
