BEIJING, March 23 (Reuters) - Australia's Fortescue

, the world's fourth-largest iron ore miner, is looking

at developing its copper resources but has not made a decision

yet, its founder and executive chairman told Reuters on

Saturday.

"The company has choices in front of it ... we have a lot of

copper options on the table. And when we feel the time is right,

we'll pull the trigger," Andrew Forrest said during a visit to

Beijing.

However, he said the company was not looking at First

Quantum's idled Cobre Panama copper mine. Cobre Panama, one of

the world's largest open-pit copper mines, was forced to shut

down in December after Panama's top court ruled that its

contract was unconstitutional.
