Riverstone Resources Inc. (TSX VENTURE:RVS)(FRANKFURT:3RV) has reported results from the first five holes from the diamond drill program on the Kao deposit, part of the Company's Karma project in Burkina Faso, West Africa.
Significant results include an intercept of 38 metres grading 3.32 g/t gold in Hole DD-10-004 and 16 metres grading 5.08 g/t gold in Hole DD-10-005 which ended in mineralization. The significant result of the drilling is that the holes intersected deeper extensions of the lowermost easterly dipping lens which opens up further exploration potential below the known mineralization. In addition, the holes confirmed the grades of the previously drilled RC holes and collected sufficient material for metallurgical purposes. Eight additional holes have been drilled and results are pending.
"We are excited about these diamond drill hole results," commented M.D. McInnis, President and CEO of Riverstone Resources. "The Kao deposit previously had only been tested to a depth of approximately 85 metres and these results demonstrate a clear potential for additional mineralization at depth. We will continue to drill this deposit aggressively." The Kao deposit consists of a series of stacked mineralized lenses, which dip shallowly to the east. All of the holes were designed to confirm intersections in previously drilled RC holes, to provide material for metallurgical testwork, and to test for deeper extensions of easterly dipping zones.
The Kao deposit is part of the Company's Karma project which 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. The resource estimate is being updated and will be released to the public by the end of February.
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.
