A Chinese state-owned iron and steel company has acquired the full ownership of a mining project in Sierra Leone.

中国一家国有钢铁公司获得了塞拉利昂一个采矿项目的全部所有权。

Shandong Iron and Steel Group say it has purchased the remaining 75-percent stake in the Tonkolili Iron Ore mine.

The price-tag for the acquisition has not been made public.

However, the company's previous purchase of the first 25 percent of the mine cost it some 1.5-billion US dollars back in 2011.

The mine has been mostly idle since November because of a debt default.
