The partnership will combine Gold Fields’ Tarkwa gold mine with AngloGold Ashanti’s Iduapriem gold mine, both located near the town of Tarkwa in Ghana. The venture is expected to produce an annual average of 900,000 oz of gold production in the first five years and 600,000 oz over the mine’s estimated lifespan. Gold Fields will hold a two-thirds stake in the JV, AngloGold a one-third stake, and the remaining stake will be held by the Ghanaian government.
