Leighton Holdings had successfully closed a US$600 million syndicated Master Lease Facility, which provides the company’s two operating subsidiaries in Indonesia with additional capacity to fund their expanding mining activities in the country.

Leighton Holdings Chief Financial Officer Peter Gregg said the new 6-year facility, which streamlines Leighton's existing Indonesian leasing arrangements, highlighted the strength of the company and its ability to secure additional funding in the current financial market.

"Leighton is in a very strong position globally with more than $46 billion work in hand and positive exposure to growth markets particularly in the infrastructure and resources sectors in Asia and Australia," Mr Gregg said.

"This new Facility will enable us to take advantage of the many opportunities available to the business in that country," he said.

Last month Leighton subsidiary Thiess was awarded a US$500 million contract extension for the further development and operation of the Teguh Sinar Abadi and Firman Ketaun Perkasa Coal Mines, near Melak in East Kalimantan.

The Master Lease Facility was arranged by the Australian and New Zealand Banking Group Limited (ANZ) and is being provided by a syndicate of nine banks.
