Riverstone Resources Inc.is pleased to report results from seventy-one reverse circulation ("RC") drill holes adjacent to the 100% owned Kao exploration permit ("Kao") deposit, which forms part of the Company's flagship Karma Gold Project in Burkina Faso, West Africa (the "Karma Project").
These holes were drilled to explore for new mineralized zones similar to that discovered at Kao, and lying to the north, north-east and south of the main deposit area (see map on the Riverstone website for the location of the holes: http://www.riverstoneresources.com/i/maps/120920R3-120713_Kao_PortPlan.jpg).
Significant assay intervals in these RC holes include:
For the south extension area:
- 1.80 g/t Au over 8 m in RC-325
- 1.58 g/t Au over 10 m in RC-336
- 1.20 g/t Au over 26 m in RC-265
- 1.05 g/t Au over 14 m in RC-269
- 16.0 g/t Au over 2 m in RC-282
- 3.94 g/t Au over 2 m in RC-279
For the north-east reconnaissance area:
- 3.67 g/t Au over 2 m and 1.16 g/t over 2 m in RC-297
- 1.38 g/t Au over 2 m and 0.90 g/t over 10 m in RC-308
- 0.96 g/t Au over 6 m including 1.72 g/t over 2 m in RC-216
- 0.75 g/t Au over 10 m including 1.48 g/t over 4 m in RC-215
Mineralization in the main Kao deposit now extends over 1,500 metres in a northeast-southwest direction and at least 900 metres down-dip to the east. The recent drilling to the south has extended the mineralized zone by about 100 metres. The Kao deposit is remains open in all directions.
Drilling to the north and north-east of the main deposit was widely spaced, and was more reconnaissance in nature. A newly defined zone of mineralization occurs some 500 metres east of the northern extent of the main Kao deposit as presently understood. Several of the holes within this 300 metre by 300 metre area returned shallow intersections of material in excess of the presently projected cut-off grade for oxide material. Further drilling will be completed to expand and define this new zone.
"We are very pleased with the discovery of the new mineralized zone as the size of the Kao deposit continues to grow," commented Dwayne L. Melrose, President and CEO of Riverstone. "We have not yet found the limits of the Kao deposit and there is very good potential to expand the mineralization to the north as the gold in soil anomaly extends 4 kilometres further to the north. We expect to have these results reflected in the upcoming resource update, slated to be available for released this quarter."
