At the end of this video, at the 9:31 point, Jim Sims says Demonstration Plant operations are expected to continue THROUGH the end of this year (meaning 2022 into 2023), although results of various testing, including rare earth recovery rates, are expected to be announced as those tests are completed. Which means in 2023 – very soon, IMHO. They CAN NOT do a Feasibility Study update until they have the data/results.
