Shares in the company behind the shelved $6 billion Oakajee port project in Western Australia have been placed in a trading halt.

Oakajee Corporation, which was managing the project north of Geraldton, announced on Monday its shares would be put into a halt pending a company announcement.

The shares, which last traded at 14 cents, are expected to remain in a halt until the start of trade on Wednesday.

Oakajee, which was backed by Japan's Mitsubishi company, last month suspended the massive deepwater port and rail project, with a lack of funding cited as the reason.
