Hounde South & Nako

The Hounde South and Nako Projects (Figure 1) were acquired in 2017. There is little historical mineral exploration over the project areas, with only broadly spaced regional stream sediment sampling completed in the area by BUMIGEB (Burkina government geological survey).

Gold anomalism was detected in the BUMIGEB survey in the south-eastern segment of the Hounde South project.  Follow up BLEG stream sediment sampling has been completed, however the samples have not yet been submitted for gold analysis.

The Nako project is located in the southern Boromo belt to the north of major gold and copper-gold systems at Batie West (Centamin) and Gaoua (B2Gold).  The project encompasses the major Boromo Shear Zone corridor where it coincides with the eastern flank of a major granitoid batholith.  A large intermediate intrusion complex hosts porphyry-style (Cu-Au) mineralisation in the tenement block.  The Kunche deposit in Ghana is located on a parallel structural corridor some 30km SE of Nako.

Regional stream sediment sampling by BUMIGEB indicates the presence of significant gold anomalism up to 75ppb in the northern part of the project.  Follow-up BLEG stream sediment sampling has been completed, however the samples have not yet been submitted for gold analysis.

Following assaying of the existing BLEG stream sediment samples, Arrow plans on completing soil geochemistry and drilling as appropriate at Hounde South and Nako in late 2019/early 2020.
