Riverstone Announces New Gold Zone at Karma

Riverstone Resources Inc. announce results from the first twenty three Rotary Air Blast (RAB) drill holes completed on the Company’s Karma gold project in Burkina Faso, West Africa. The holes were drilled in the immediate area of the GG1 deposit, one of four deposits that comprise the Karma project, to test several gold-in-soil geochemical anomalies with the objective of locating new mineralized areas.

Eleven of the twenty-three holes returned anomalous values in gold ranging from 269 ppb to 1.44 g/t over widths ranging from 3.0 metres to 51.0 metres. A number of the anomalous holes require additional offset drilling to determine if there is any continuity of the mineralization. However, six of the holes have established a new 700 metre long zone that is still open to the west. The six holes were drilled to test a gold-in-soil anomaly that is parallel to and south of the known GG1 mineralization and could represent a new area of mineralization.

“We are very encouraged by the results to date from the RAB drilling,” commented M.D. McInnis, President of Riverstone. “The objective of our current drilling program is to locate new zones of mineralization adjacent to our known NI 43-101 compliant resource at Karma. The initial results certainly require a follow-up RC drill test to determine if we have discovered a new zone.”

The ongoing drill program at Karma comprises up to 6,000 metres of drilling, divided roughly equally between reverse circulation drilling (RC) and rotary air blast drilling (RAB). The planned RAB drilling has been completed; 60 RAB holes totaling 2,857 metres were drilled in the area of the Goulagou (GG1 & GG2) deposits and 15 holes totaling 751 metres were drilled near the Rambo deposit. RC drilling has commenced on the Kao Permit.

The Company maintains a rigorous quality control program involving the use of repeat assays, inserted blanks, and the use of certified standards from an accredited Canadian laboratory. All RAB samples were assayed using standard fire assay with atomic absorption techniques, with samples grading in excess of 2.00 g/t gold 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.
