Straits' chief executive Milan Jerkovic said the outlook for Sebuku for the year was very positive and would ensure a strong financial performance for the company.
In the September quarter of last year the Sebuku mine generated sales revenue of $31 million for Straits, via its then 80% stake. Straits has operated the mine since 1998 and increased production to current levels of 2.6 million tonnes per annum.
The deal is still subject to shareholder approval.
