Rwanda has signed a five-year mining contract worth $39-million with a unit of Oman’s Mawarid Mining to extract tin, tantalum and niobium, the mining ministry said on Tuesday. Mining, which the government says contributes about 1.5% of Rwanda’s $7.9-billion gross domestic product, is the East African country’s second-biggest source of foreign exchange behind tourism, with metallic ore coltan bringing in the most earnings.
