African Minerals Ltd. (AMI), studying a $2 billion iron-ore mine expansion in Sierra Leone, is considering acquisitions in commodities such as copper and steelmaking raw materials.

“There are significant opportunities in West Africa, across commodities and across countries, that we will be extremely well-positioned to take advantage of,” Chief Executive Officer Keith Calder said in a phone interview from London today, adding that his primary focus is the existing Tonkolili mine and Pepel expansion project.
