But the core of the business remains iron ore, with shipments of 48.9 million tonnes in April to June contributing to record shipments of 192 million tonnes for the financial year.
"Building on another year of record performance, our guidance for FY24 is for total shipments in the range of 192 to 197 million tonnes," chief executive Fiona Hick said in a statement to the ASX on Thursday.
Fortescue said it was focused on ramping up Iron Bridge in the Pilbara region of Western Australia, while the Belinga iron ore project in West Africa has had its first ore loaded and delivered to port during the quarter.
Decarbonising iron ore operations are also a focus along with a rebranding of Fortescue's global green energy division as Fortescue Energy, which comprises Fortescue Future Industries (FFI) and WAE Technologies.
Unaudited operating expenditure for big-spending FFI was $US440 million for FY23, exclusive of expenditure incurred on behalf of Fortescue Metals for decarbonisation.
"The group will continue to invest in green metals, green energy and green technologies, supported by our strong balance sheet and disciplined capital allocation," Ms Hicks said.
Iron ore exploration in the Pilbara included resource definition drilling in the Eastern Hamersley with a focus on Nyidinghu and Mindy South.
Other exploration activity in Australia is focused on copper, including in South Australia where geophysical data processing and modelling is being finalised for drill testing by the end of calendar 2024.
Fortescue's cash balance increased to $US4.3b at June 30, from $US4.0b at March 31.
