Arrow Minerals Limited (ASX: AMD) reports that assay results from the first reverse circulation (RC) drilling at the Divole East project in Burkina Faso have confirmed the extension of known and interpreted gold-bearing structures.
Arrow’s Chief Executive Officer, Howard Golden, said the 24 hole RC drilling programme (total 2,385m, average 99m) intersected gold mineralisation at each of the three targets tested:
- a sheared porphyry intersected in first-pass 2017 drilling;
- an interpreted N-S shear zone; and
- laminated quartz veins.
“Three distinct types of mineralisation were interpreted by the Arrow technical team at Divole East,” Mr Golden said.
‘All three gold-bearing structures were confirmed in widely spaced drilling, and all three yielded gold values that warrant aggressive follow-up programmes. Nine of the holes returned over 2g/t Au, with the best hole, DERC19002, intersecting 2m @ 4.8g/t Au.
“In addition, drilling at Divole Main has significantly extended the mineralised porphyry discovered by diamond drilling in 2017, which intersected up to 9.9m @ 4.3g/t Au.
“The porphyry remains open in all directions and Arrow has applied for a licence extension covering the western extension of the gold-bearing porphyry.
“When the drilling season in Burkina Faso returns in 4Q 2019 we will be looking to increase the area of continuous gold mineralisation in all three Divole East target areas.
“We will also expand our exploration efforts to our other Burkina Faso licenses, commencing with an RC drill programme at Divole West.”
The maiden RC drill programme at Divole East was designed to test multiple zones in a prospective Birimian Greenstone Belt in Burkina Faso that was acquired after regional analysis. Soil geochemistry, auger drilling, geophysics and geological mapping all contributed to the definition of the three targets drilled in July 2019.
