Arrow Minerals encouraged by results that extend Dassa gold discovery
Arrow completed 2,215 metres of RC drilling in July and August 2020
Arrow Minerals Ltd (ASX:AMD) is encouraged by results returned from recently completed reverse circulation (RC) drilling that extends Dassa gold discovery within the Divole West project in western Burkina Faso.
The drilling was aimed at expanding known mineralisation and now, gold mineralisation has been discovered in two zones, each over 600 metres long, with both remaining open along strike and down-dip.
Significant shallow gold intersections include:
- 6 metres at 1.1 g/t from 61 metres;
- 4 metres at 1.1g/t from 113 metres; and
- 1-metre at 1.9g/t from 35 metres.
Arrow’s managing director Howard Golden said: “The drilling was curtailed due to the intensity of the seasonal rains. Nevertheless, 2,215 metres of RC were completed.
“The results were encouraging, bringing into focus the two zones of significant shallow gold mineralisation.
“Further, the mineralised zones continue into untested areas both north and south where drilling will continue when drier conditions return in Q4 2020.”
Arrow completed 2,215 metres of a planned 3,500 metres program of RC drilling in July and August 2020 at the Dassa discovery.
Nine of the 21 completed holes contained shallow intervals greater than one gram-metre gold and seven holes were abandoned before they reached the target depth.
Results are valuable and will allow Arrow to pursue a targeted program of drilling in the December quarter to extend the known gold mineralisation.
There is good potential for mineralisation to extend down-dip to the southeast, where the deeper sediment-granite contact target zone was difficult to reach due to the significant water inflow.
The results showed that gold is present all along the 3-kilometre strike drilled to date, the highest grade and thickest gold mineralisation is resolving into two large bodies separated by a structurally offset zone hosting lower grades of gold.
Next steps in Burkina Faso
Dassa remains open and further drilling is planned next quarter aimed at growing the discovery with a focus on expanding the north and south zones of mineralisation
Deeper drilling down-dip to the southeast to determine the extent of mineralisation along the contact target zone will allow the company to deepen some holes that it was unable to intersect due to unfavourable drilling conditions during the rainy season.
Arrow also plans surface mapping and geochemical sampling on its expanded Divole permits as well as on the Boulsa and Nako permit blocks.
The company will undertake an airborne electromagnetic survey of volcanogenic massive sulphide (VMS) copper-gold anomalies on its Strickland project in Western Australia, which is expected to be completed before mid-October.
