African Gold (ASX:A1G) said drilling at its Blaffo Guetto prospect, part of the Didievi gold project, in the Ivory Coast, continues to extend mineralisation along strike and at depth, according to a Monday Australian bourse filing.

The results show a robust and expanding system with strong grade continuity, the filing said.

A resource update is currently underway, and follow-up variability and optimisation programs are being planned at the project, the filing added.
