I would also point out that Tasman has a fair bit of eudialyte in their ore. Eudialyte can definitely be leached with sulfuric acid. In the past, though, the problem was that the eudialyte produced a gel-like effect in the leach. Matamec has a eudialyte, as well. That may be related to their recent announcements regarding Toyota’s involvement, I don’t know. But eudialyte is not generally regarded as positive. All the issues related to eudialyte are relatively easy to deal with on the bench, much less easy at commercial scale.
