South32 hits IGO with $80 million royalty lawsuit

South32 is requesting a 1.5% soil sample royalty payment on the gross revenue that IGO earned from December 2014 until September 2023, when it had a stake in the mine.

A 2002 deal between South32 and IGO gave the former the right to receive royalty payments if IGO found any minerals from the soil samples it collected under the exploration licences. This is the basis of South32’s claim, IGO said in the statement.

The embattled nickel and lithium miner said it considers South32’s allegations to be without merit.

Tropicana, about 300 kilometres north-east of Kalgoorlie, began operations in 2013 and is now owned by AngloGold Ashanti (JSE: ANG) (NYSE: AU) in partnership with Regis Resources (ASX: RRL).

The open-pit, with a growing underground mining component, produced 437,000 ounces (100%) in 2022.

Regis, which bought its stake in Tropicana from IGO in 2021, went into a trading halt on Thursday before issuing a statement saying it was not a party to the legal action pursued by South32, but “would take appropriate action to defend its position”.

News of the lawsuit came on the heels of IGO announcing it had placed its Cosmos nickel project in Western Australia into care and maintenance due to low prices. The company also lowered its annual lithium production forecast.
