The company was awarded a $60-million contact by OceanaGold to build site accommodation and related earthworks, a tailings storage facility, and the open cut mining for the first phase for the Didipio gold and copper mine.

Leighton Asia also secured a six-year relationship-based contract valued at $170 million to undertake mining operations at the Masbate Gold Mine in the Philippines.

"In addition to mining services, Leighton, in partnership with Lycopodium Limited, is currently designing and constructing the gold processing plant for the project which is scheduled to be completed in early 2009," Leighton said.

"Mining operations are due to commence in September 2008."

Earlier in Hong Kong, Leighton Asia's joint venture with China State Construction Engineering secured an $80-million contract to build an aircraft maintenance hangar at the Hong Kong International Airport (HKIA).

Construction started in March and is expected to be completed in May 2009. (By Yuinmunn Szetoh)
