Western Ethiopia Project

The Western Ethiopia project is divided into four prospects - Ashashire-Dul, Menghe, Agusha West and Agusha East - with dedicated teams to develop the program. 

  • License is located in core of Tuludimtu Orogenic Belt, a c.500km long and 200km wide zone of deformation that forms part of the greater East African Orogen
  • The NS trending Tuludimtu Orogenic Belt is of Neoproterozoic age and forms part of the Arabian-Nubian Shield
  • Interpreted to be a collision belt formed during assembly of Western Gondwana
  • Known gold mineralization is associated with hydrothermal fluids resulting in precipitation of Au in quartz veins
  • Au is also associated with structural contacts between granitic terrains and mafic volcano-sedimentary sequences (“typical” greenstone belts)
  • Au mineralization is known to be related to D1 and D3 deformations during tectonic events
  • The structural deformations have been mapped in all the targets, with the Menghi prospect being the most structurally complex (potentially highest interest)
  • The Azale target presents a third style of mineralization : VMS (Volcanogenic Massive Sulphide) (License application)
  • Gold “particles” commonly observed in the field in quartz samples

Mineralization styles

  • Structurally shear hosted mineralization consisting of low to moderate sulphide (disseminated pyrite, chalcopyrite, sphalerite) and rare fine gold specks. Alteration consists of silicification and carbonatization, sericitisation and tourmalinsation
  • Massive mineralized quartz ribbon vein, probably boudinaged. Mineralization comprises of pyrite, chalcopyrite and gold
  • Gold bearing quartz stockwork comprising tensional and flat veins

Agusha West

Two key areas have been identified in Agusha West – Tsilfa and Hulook. While neither is a priority target for Aurigin Resources, they represent significant growth potential for the company and detailed early-stage exploration has been completed. Geochemical soil results confirm the presence of Au in both areas.

    Tsilfa

  • N-S trending quartz vein hosted in sulfide bearing silicified meta-volcanics
  • Results of chip samples in quartz vein: 7.65, 3.85, 6.15, 5.30, 3.44, 1.94, 2.81 g/t Au
  • 140m wide by 220m long Au anomaly with peak values of 121, 106, and 365 ppb Au in soil samples

    Hulook

  • N-S trending Hulook quartz veins hosted in sericitized-silicified meta-volcanics
  • 5 and 8 Au grains in 2 out of 3 crush samples from quartz veins
  • 160m wide by 340m long Au anomaly (with peak values of 500, 740, and 1,540 ppb Au) in soil samples

 

Agusha East

  • Regional geochemical sampling 
  • Outstanding gold-in-soil anomaly (6.5km x 250m)
