Riverstone Resources Inc. (TSX VENTURE:RVS)(FRANKFURT:3RV) has announced that additional results from the Reverse Circulation drilling at the Kao gold deposit in Burkina Faso, West Africa, has extended the gold bearing zone further along strike and at depth.
The deposit remains open to the north, to the east-northeast and at depth to the east along the shallowly plunging mineralized zone. The Kao deposit is one of four that collectively comprise the Company's advanced stage Karma gold project.
Significant results were received from the holes drilled at depth to the east, which were designed to intersect the down-dip extension of the mineralized zone at a vertical depth of 100 metres below surface. Drill hole RC-207 intersected 0.77 g/t gold over 44 metres, including 0.96 g/t gold over 28 metres. Drill hole RC-208 to the south intercepted two zones grading 1.24 g/t gold over 12 metres and 1.08 g/t gold over 6 metres respectively. The Kao deposit is an approximately 40 metre thick tabular zone which dips 25 degrees to the east. The shallow dip potentially means that the deposit could be traced at greater depths than presently outlined and still be amenable to open pit mining.
On the north-eastern edge of the deposit, drill hole RC-206 intersected 1.30 g/t gold over 26 metres, including 2.39 g/t gold over 10 metres. The deposit is open to the northeast and to the east beyond this intercept, and it also remains open to the north, based on previously reported results (see News Release dated Dec 6, 2010).
The RC drilling at Kao which commenced in October totalled 3,346 metres, mainly on a series of fences to the north and northeast of the current NI 43-101 compliant gold resource.
The drilling on Kao is part of a 25,000 metre drill program on Karma, which commenced in October and will continue until March 2011. The program consists of at least 15,000 metres of Reverse Circulation (RC) and 10,000 metres of diamond drilling. In addition to the RC drilling on Kao, RC drilling will be carried out on Goulagou I in an effort to expand the strike length of the mineralized zone. The majority of the diamond drilling will be carried out at the Company's Nami gold zone where artisanal miners are actively working an area of approximately one kilometer by 500 metres.
The Company is currently updating the gold resource estimate on the Kao gold deposit and on the other three deposits, Goulagou I, Goulagou II and Rambo Main, which comprise the Karma resource, and anticipates that a new resource estimate will be completed in Jan 2011. The Karma project currently comprises a NI 43-101 compliant gold resource of 820,500 ounces of gold in the indicated category and 322,300 ounces of gold in the inferred category.
