ioneer signs binding lithium offtake agreement with Toyota / Panasonic JV PPES

Australia-based ioneer, an emerging lithium–boron supplier, signed a binding offtake supply agreement with the Prime Planet Energy & Solutions (PPES) joint venture between Toyota Motor Corporation and Panasonic Corporation, in which ioneer will supply PPES with lithium carbonate from its Rhyolite Ridge Lithium-Boron Project in Nevada. (Earlier post.)

PPES is a battery production company established through joint-investment between Toyota and Panasonic.

Under the agreement, ioneer will deliver 4,000 tons per annum (tpa) of lithium carbonate to PPES over a 5-year term. PPES will utilize ioneer’s lithium carbonate to produce batteries for use in US electric vehicles.

ioneer is expected to produce an annual average of approximately 20,600 tonnes of lithium carbonate/hydroxide along with approximately 174,400 tonnes of boric acid per year over the Rhyolite Ridge project’s 26-year life. The dual production of lithium and boric acid allows ioneer to not only produce lithium in the US, but to do so at the very bottom of the global cost curve. ioneer anticipates commencing production in 2025 to support urgent requirements for battery materials in the United States.

This agreement follows two earlier binding offtake agreements with Ford and EcoPro and, in total, represents the completion of pre-production lithium carbonate supply commitments the company currently intends to make for Rhyolite Ridge.

Key terms of the agreement with PPES include:

  • Product: Lithium carbonate

  • Contract Duration: 5 Years

  • Volume: 4,000 tpa

  • Price: Adjusted quarterly based on agreed price formula

  • Currency: USD per metric ton

  • Conditions Precedent: ioneer’s Final Investment Decision
