Major Suppliers & Offtake Partners

Engineering and Major Suppliers
Ioneer has partnered with best-in-class partners for the engineering, construction and management of the mine, including well known firms such as Fluor who led the work on the Feasibility Study and is EPCM on the Project, Caterpillar, and Veolia.


Lithium offtakers
Our Definitive Feasibility Study released in April 2020, estimated that the Rhyolite Ridge Project would produce an average of 20,600 tonnes annually of lithium carbonate equivalent (LCE) over the projected 26-year life of mine. In June 2021, we announced that South Korean chemicals company, EcoPro, the world’s second largest cathode producer, had signed an offtake agreement with Ioneer for 2,000 tonnes annually, this was uplifted to 7,000 tonnes annually in February 2022. Additionally, in July and August 2022 respectively, offtake agreements were signed with the Ford Motor Company and Prime Planet Energy Solutions – a joint venture between Toyota Motor Corporation and Panasonic Corporation. In May 2023, Ioneer announced an offtake agreement had been signed with Dragonfly Energy Holdings Corp., a Nevada based industry leader in energy storage, for a variable amount of surplus tons available after meeting previously announced offtake commitments.
Boron offtakers
Boron is a very significant co-product, accounting approximately 30% of revenue at Rhyolite Ridge. Its reliable and steady revenue contribution helps secure Rhyolite Ridge at the bottom of the global lithium cost curve.
Ioneer has three offtake agreements in place for its boric acid production, which were announced in FY 2020 and together account for 100% of Ioneer’s first year of boric acid production and over 80% of years two and three boric acid production.
The contracts include:
- A binding offtake agreement with Dalian Jinma Boron Technology Group Co. Ltd for 105,000 tonnes per annum of boric acid for five years and includes a distribution agreement for the territories of China and Taiwan.
- A three-year sales and distribution agreement with Kintamani Resources Pte Limited for the territories of Malaysia, Indonesia, Singapore, Thailand, Vietnam, and the Philippines.
