Exploration and Deposit Types
The Arabian-Nubian Shield is believed to be the next major exploration frontier in Africa, like West Africa's mineral exploration boom. The ANS mineral potential has yet to be fully explored and extends into the countries Egypt, Sudan, Eritrea, Ethiopia, Djibouti and Saudi Arabia. It is host to a variety of deposit types, mesothermal gold or polymetallic, quartz vein gold and volcanogenic massive sulfide ore deposits ("VMS"). The mineral types are many, and is host to gold, copper, zinc, tantalum, silver and potash. The dominant deposit types are volcanogenic massive sulfide ore deposits and gold quartz vein deposits.
A list of VMS deposits in the Arabian-Nubian shield
- Bisha VMS deposit in Eritrea - Nevsun Resources
- Hassai VMS deposit in Northern Sudan - La Mancha Resources
- Jabal Sayid in Saudi Arabia - Barrick Gold
- Hamama VMS deposit in Egypt - Alexander Nubia International
The polymetallic nature of VMS deposits typically mean substantial capital costs to explore and develop than gold only deposits in the Arabian-Nubian shield such as the Sukari gold mine in Egypt.
