Judgment day in court battle for Hancock mining riches

The complex battle pitted Rinehart’s company, Hancock Prospecting, against the heirs of mining pioneer Peter Wright and engineer Don Rhodes amid allegations of decades-old contract breaches.

They fought over the spoils of the huge Rio Tinto-operated Hope Downs mining complex in Western Australia, and a verdict will be handed down today.

Wright Prospecting demanded a share of Hope Downs’ unmined and mined tenements and royalties, amid a claim that Hancock Prospecting had breached a 1980s partnership agreement.

DFD Rhodes also claimed a royalty share in Hope Downs production, due to an alleged deal with Rinehart’s father Lang Hancock and Wright involving the transfer of tenements in the 1960s.

The painful encounter involved Rinehart’s eldest children, John Hancock and Bianca Rinehart, over a claim that their grandfather had left them a sizeable share in the Pilbara mining resources he discovered in the 1950s.

Mining giant Rio Tinto was also a party to the High Court battle as a joint venture partner in Hope Downs and could be on the hook financially depending on which way the judgment goes.

The 51-day trial included sensational allegations against Rinehart – which were vehemently denied – including that she had devised an illegal scheme to defraud her children.

About two dozen of the country’s “brightest legal minds”, costing an estimated $250,000 a day, packed a Perth courtroom for a hearing ending in December 2023.

Judge Jennifer Smith said at the time that the case would “rely on a review of the vast body of historical documents.”

Rinehart inherited her father’s iron ore discovery in the Pilbara region and forged a mining empire after he died in 1992.

It developed mines from tenements at Hope Downs and in 2005 signed an agreement with Rio Tinto, which has a 50 percent stake in the project.

The Hope Downs mining complex near Newman is one of Australia’s largest and most successful iron ore projects, with several open-pit mines.

Rinehart’s net worth is estimated at around $40 billion and she is the executive chairman of Hancock Prospecting.
