Trading in Australian iron ore miner (and Jubak’s Pick) Fortescue Metal (FSUMF.PK) has been halted in anticipation of the release of news on Monday that the company has completed a  ”commercial negotiation”.

Speculation in Australia is that the news will be that China’s sovereign wealth fund, China Investment Corp. (CIC), has decided to invest $1 billion into Fortescue. CIC, rumors go, will get convertible bonds in exchange for its cash.

The new money would go a long way toward funding Fortescue’s goal of expanding producton to an annual 95 million metric tons by sometime in 2012. Production is now running at a rate of about 35 million tons a year.

Reaching production of near 100 million tons (which would put the company a solid third among the world’s iron miners behind Vale (Vale) and BHP Billiton (BHP)) is essential for the company to reach a scale that it would let it bring down production costs to the levels now enjoyed by its bigger competitors.

Industry analsyts estimate that reaching a 95 million ton annual production rate would cost Fortescue$3 billion. Right now the company has about $650 million in cash.
