SYDNEY, Dec. 7, 2022 /PRNewswire/ -- Ioneer Ltd ("Ioneer" or "the Company") (ASX: INR, Nasdaq: IONR), an emerging lithium-boron supplier, announces the signing of a non-binding Memorandum of Understanding (MOU) with Shell Canada Energy ("Shell") for sale of sulphur to Ioneer for its Rhyolite Ridge Lithium-Boron Project ("the Project") in Esmeralda County, Nevada.

Securing the supply of key reagents for ore processing is an important step along the critical pathway to developing the Rhyolite Ridge Project. Under the MOU, Ioneer will purchase up to 500,000 tonnes of high-quality sulphur annually from Shell, which would fulfil the estimated annual sulphur requirement for the Project.

The signing of the MOU builds upon the Letter of Intent (LOI) signed in December 2019 and, with a binding commitment to negotiate exclusively with one another, it is the intention of both parties to advance the MOU into a Definitive Agreement at the appropriate time.

Ioneer and Shell also intend to collaborate through strategic initiatives focused on accelerating the energy transition.

Ioneer's Managing Director, Bernard Rowe, said:

"With this MOU, Ioneer takes another key step to secure sulphur for the Rhyolite Ridge Lithium-Boron Project. Sulphur is a primary input for our process as it will be converted into the sulphuric acid required for leaching the ore as well as releasing heat which is recovered to produce carbon free power and steam for the facility.  Shell is an ideal partner for this effort, and we look forward to furthering our partnership together on additional decarbonisation solutions while providing materials for a sustainable future."

Peter Zissos, GM Global Sulphur & Thiogro from Shell, highlighted:

"We are excited to expand our partnership with Ioneer to include the sale of sulphur while collaborating on various decarbonisation solutions. Sulphur's second largest use is for mining, including for the extraction of EV metals like lithium. With safe and reliable delivery of sulphur to customers like Ioneer, Shell Sulphur Solutions is delivering inputs critical for renewable energy production and management."

This ASX release has been authorised by Ioneer Managing Director Bernard Rowe.
