Arrow Minerals Limited (ASX: AMD) has been successful in extending the strike-length at its promising Dassa gold discovery within its Divole West project in western Burkina Faso to over 3km.
The company now has a much clearer understanding of the discover after completing its reverse circulation (RC) drilling campaign at Dassa, along with a campaign of air core sampling of saprolite (weathered bedrock) under transported soil cover.
Managing Director, Howard Golden, said the RC results show that mineralisation extends down-dip to the east, while the air core results confirm continuous gold anomalism extending for >3km and open to the north, south and east.
“This recent round of drilling on the Dassa gold discovery has significantly extended the mineralisation to the east and confirmed a >3 km long continuous zone that hosts significant gold mineralisation,” Mr Golden said.
“The Dassa gold discovery remains open to the north, south, east and down- dip to the east. We look forward to completing further drilling to grow the Dassa gold discovery, still in its early days after the maiden drilling programme just two months ago.”
The now completed, shallow drilling programme at Dassa comprised of 1,961m of RC drilling, following up 4,214 m of RC drilling for a total of 55 holes or 6,175m.
The RC drilling also confirmed that the gold mineralisation at Dassa continues to the northeast, where it remains open towards the northern extension of the Divole West permit. Highly anomalous gold in drill holes to the southwest points to further exploratory work along the >3 km southwestern continuation of the strike direction on the Arrow permit.
Further drilling is now planned early Q2 2020. This next round of drilling will include a mix of auger and air core drilling, which has been shown to be very effective in targeting gold at Dassa. These techniques will be employed to the south of the known Dassa mineralisation in the coming month.
A similar auger/air core program is planned to the north of the Dassa mineralisation within the northern sector of the Divole West permit.
The existing RC profiles will be extended even further to the east and at depth by April 2020 to follow the known continuous gold mineralisation.
The central portion of the Dassa mineralised zone will be tested with deeper RC drilling. This drilling will be completed by April 2020 to infill the remaining portion of the >3 km strike length and demonstrate the potential for Dassa to become a large, coherent, shallow block of mostly oxidised gold mineralisation.
