Yunnan Aluminium Co Ltd <000807.SZ> plans to raise 1.06 billion yuan by issuing six-year convertible bonds with detachable warrants to help fund an alumina project, the company said in a filing with the Shenzhen Stock Exchange on Monday.

    The project, in Wenshan in southwestern China's Yunnan province, will have annual alumina production capacity of 800,000 tonnes. It will require total investment of 4.5 billion yuan and take three years to complete, the company said.

    Yunnan Aluminium said shareholders had approved the bond issue to domestic investors, with preference to current shareholders.

    It did not specify a price or issuance date. It added that funds raised through the exercise of the warrants would not exceed the amount of funds raised via the bond issuance.
