Riverstone intersects 2,39 g / t gold on 24 meters at Kao
Riverstone Resources Inc. (TSX-V: RVS) ("Riverstone" or the "Company") is pleased to announce the results of 17 diamond drilling at its 100% proprietary Kao deposit ("Kao"), which is part of the company's flagship gold project Karma (the "Karma Project") in Burkina Faso (West Africa) is to announce. These holes are part of a drill program in the northeastern extension of the Kao Main Deposit to further investigate the extent of the eastward-impacting mineralization (See map on the Riverstone website for drilling location: http://www.riverstoneresources.com/i /maps/120911-120713_Kao_PortPlan.JPG).
Significant study sections of these holes include:
• 2,39 g / t Au on 24 m in DD-12-130
• 2,22 g / t Au on 16 m including 3,28 g / t on 8 m in DD-12-139
• 2,10 g / t Au on 12 m in DD-11-069
• 2,02 g / t Au on 12 m in DD-12-149
• 31,8 g / t Au on 2 m and 2,42 g / t on 6 m in DD-12-131
• 1,84 g / t Au on 14 m in DD-12-72
The mineralization at Kao extends over 1.400 meters from northeast to southwest and at least 900 meters along the dip to the east. These recent holes confirm the continuity of the higher grade ore along strike to the northwest and in depth. The deposit is still open to the north, south and eastward.
"Kao's extension drilling continues to yield grades above the modeled average grade of the deposit," said Dwayne L. Melrose, President and CEO of Riverstone. "This is expected to have a positive impact on the upcoming resource estimate, which is on track to be completed by the end of September, 2012. The updated resource model has the potential to extend mine life or increase annual gold production. These parameters were determined in the recently published results of the initial economic evaluation. "
For a more complete summary of the significant results of these holes, see the table below:
KAO's 100% proprietary deposit is part of the Karma Company's in-pit Whittle 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 Gold in 18,9 includes millions of tonnes grading 0,93 g / t gold (see 9 January 2012 press release and NI 43-101 "Technical Report" entitled "Technical Report and Resource Estimate on the Karma Project, Burkina Faso,"). West Africa ", which was submitted to SEDAR (www.sedar.com) on 23 February 2012). The Company has completed more than 85.000 meters of drilling on the Karma Project since the resource estimate date. The results of these drillings are expected to expand the overall resource of the Karma project deposits. Recently, the results of a Preliminary Economic Assessment (see 20 News Release August 2012) highlight that the Karma project is robust from an economic point of view.
Riverstone applies a rigorous quality control program that includes repetitive testing, the addition of blanks, and the use of certified standard samples from accredited Canadian laboratories. All samples were processed in the independent laboratory Abilab Burkina SARL (part of the ALS Chemex Group) in Ouagadougou (Burkina Faso) and investigated by means of an industry-standard fire assay with atomic absorption completion. Samples containing more than 1 grams of gold per tonne were re-analyzed with a gravimetric finish in Burkina Faso or at the ALS Chemex facility in North Vancouver, British Columbia, Canada.
Riverstone is primarily involved in Burkina Faso, West Africa, where the company has four high quality exploration projects spanning more than 2.000 square kilometers.
