March 11 (Reuters) – Australian mining major Rio Tinto said on Wednesday it had secured ​a $1.175 billion financing package from ‌four international lenders to support development of its Rincon lithium project in Argentina’s Salta province.

The package includes ‌loans ​from the International ⁠Finance Corporation, a member ⁠of the World Bank Group, IDB Invest, Export Finance Australia and the Japan Bank for ​International Cooperation.

Proceeds from the financing will support development of ⁠the $2.5 billion Rincon ⁠project, which is targeting ​annual production of about 60,000 tonnes ​of battery-grade lithium carbonate, the ‌company said.

Rio said the financing package would diversify funding sources for the project as the ⁠miner advances its lithium growth pipeline to meet demand linked to the global ⁠energy ‌transition.

The Anglo-Australian mining company, ⁠on Tuesday, announced its ​first ‌commercial shipment of lithium ​carbonate produced ⁠at the Rincon project, marking the formal start of exports from the northern mine.
