Riverstone Resources has announced the results from 14 diamond core (DD) holes drilled at the Kao Deposit. This deposit forms a portion of the company's flagship Karma Gold project located in West Africa.
Location of the drill holes
These DD holes were drilled in the Kao main zone’s southern parts and form part of a drilling campaign specifically designed to explore and outline shallow, high-grade gold oxide mineralization.
The company encountered 2.09 g/t gold over 32 m in DD-12-154; 1.84 g/t gold over 28 m in DD-12-155; 2.37 g/t gold over 8 m and 1.19 g/t gold over 22 m in DD-12-158; 3.63 g/t gold over 14 m and 2.92 g/t gold over 32 m in DD-12-160; 2.39 g/t gold over 8 m in DD-12-161; 3.11 g/t gold over 18 m in DD-12-163; and 1.73 g/t gold over 14 m in DD-12-164.
Currently, the Kao mineralization expands at least 900 m down-dip to the eastern part and over 1,400 m towards northeastern and southwestern parts. These new holes show the occurrence and continuation of high-grade gold mineralization zones in the shallow oxide material. The company has drilled several additional holes at the Kao deposit and is waiting for these drilling assays, which may become available in August and September.
According to Riverstone’s CEO and President, Dwayne L. Melrose, the company is considerably encouraged with the high-grade assays from the Kao drilling program. These drilling results are quite encouraging as they validate the high-grade shallow oxide material continuity at the Kao deposit. So far, the limits of the deposit have not been identified. Riverstone is striving to extend the deposit. The future resource calculation planned for this September will include these results. The Karma project’s preliminary economic assessment, which is now being performed, is advancing as per schedule and is anticipated to be reported in August 2012.
