July 8 (Reuters) - Australian lithium miner Ioneer said on Wednesday that it has signed separate non-binding memorandums of understanding with South Korea's KIND and Hyundai Engineering to help advance its Rhyolite Ridge lithium-boron project.

Here are some details:

o Under the MOUs, Korea Overseas Infrastructure & Urban Development Corporation (KIND) is considering an equity investment in the project, and Hyundai Engineering is evaluating the provision of certain procurement-related activities for the project.

o The MoUs were signed by the firms' executives at the U.S. Department of Energy offices in Washington.

o "With the entry into MOUs with KIND and Hyundai Engineering, we are one step closer to a Final Investment Decision," Ioneer Executive Chairman James Calaway said.

o Once operational, Rhyolite Ridge will process ore into final products entirely on-site and create and support 275 to 300 permanent positions in rural Nevada, Ioneer said.

o Ioneer said there can be no certainty that the MOUs will lead to legally binding agreements.
