Tanzania’s government is in talks with mining companies to raise royalty payments on gold exports as well as negotiating other possible tax hikes. African Barrick Gold has four gold mines in Tanzania while Australia’s third largest gold miner, Resolute Mining and South Africa’s Anglogold Ashanti (with a listing also in London) also have gold mining operations there. British mining company African Eagle Ltd is raising funds for its nickel project in Tanzania.
