It's been another big year for Perth billionaire Andrew Forrest for both his mining and philanthropic endeavours. But not all his investments have fared well.

Forrest is chairman and major shareholder of Fortescue Metals Group, and in three weeks' time he will receive a $260 million dividend cheque following the iron ore miner posting a net profit after tax of $US985 million in the year to June 30.

The Financial Review Rich Lister received about $200 million from a Fortescue interim dividend payment in February.
