Fortescue Metals is mulling to issue bonds worth around $1 billion, The Wall Street Journal reports. The bond sale will be part of the iron-ore miner’s plan to spend on its major expansion in Western Australia.

The Australian miner will focus on the U.S. bond markets, but will also be open to offers from Chinese lenders. Fortescue is also considering spending $8.4 billion during the next two years to increase its production three times in Pilbara.
