Do they have samples?

What were the main findings of the Definitive Feasibility Study (DFS) completed in 2020?
The DFS concluded that we would develop an open pit mine operation. We have a hard rock deposit, and we will use conventional mining methods to extract the rock. That rock will be processed on-site to extract the lithium and boron from it. Then, these will be refined and processed to make the end-product lithium chemicals at the site, which is very unique among hard-rock operations around the world. The DFS also confirmed our ability to produce approximately 22,000 mt/y of lithium carbonate or lithium hydroxide, and 174,000 mt/y of boric acid for 26 years.

How did ioneer’s pilot plant help to understand the most effective way of processing the boron-lithium ore?
We constructed a full simulation pilot plant, where we reproduced each part of the process from the rock to the end product. Rather than using new technology, we adopted technologies from existing copper, lithium and boron mining operations, bringing them together in one process plant to suit our unique deposit. We decided to use a large-scale pilot plant instead of working with small samples in a lab because this allowed us to observe how things will behave more precisely at commercial scale, without large variations.
