Murchison Metals is discussing selling its stake in the Jack Hills iron ore mine and troubled Oakajee Port and Rail project in WA's midwest.
Murchison halted trading in its shares before the market opened on Monday, after receiving an offer.
The $6 billion project hit a hurdle in June when joint venture partner Murchison admitted it could not fund its share of one of Australia's biggest infrastructure schemes.
Murchison's shares last traded at 27.5 cents after trading at $1.27 in January.
