Ann: 5EA to Host Special Call for Investors, page-2

I would have a couple of questions.

1) In the previous 2021 eDFS cash costs for Boric Acid were estimated at USD -75. They were negative thanks to USD 578 SOP by product credit. What changed with SOP production assumptions, as it has for now been shelved?

2) Capex estimate has approximately doubled since then. How much is due to a) possibly adding equipment missing in 2021, b) due to cost inflation, c) due to Li by-product d) how much was saved due to no SOP production?

3) Sulfuric acid H2SO4 is now only used to recycle HCl. Is it an option to leach directly with H2SO4 and not use HCl at all, thus simplifying the process?

4) A couple of Li projects in Nevada plan to use monstrous amounts of sulfuric acid, some of them far away from railroad hubs. Could sulfuric acid become a bottleneck in the future?

5) What kind of results from the small scale plant could lead to significantly different, esp. lower capex/opex?
