Mine Operations

The Republic of Liberia is situated on the coast along the south-west corner of West Africa, bordered by Sierra Leone, Guinea and Cote d’Ivorie. It is Africa’s oldest republic, founded by freed American and Caribbean slaves in 1847. It has had democratically elected governments since 2006. It has robust mining laws based upon well-established Australian system and a pro-mining government. The region is under-explored for gold.

The company has five operational underground gold mines and one open-pit project is currently in state of development in Liberia.
