Jubilee Metals (JUB) is hoping to follow in Central Asia Metals’ (CAML) footsteps by buying into a copper tailings resource. The Africa-focused company won’t get full ownership of the waste deposit but is also only putting up $600,000 (£481,000) in cash, on top of $4.4m in shares for 75 per cent of earnings from the project until 1.5 times its investment is paid off.
