We first started discussing this tenement when I mentioned it in August 2016.. this particular post may shed some light on the legal proceedings for you: https://hotcopper.com.au/threads/an...pdate-thx-ax.2826201/page-14?post_id=18423778

in terms of your other questions, sorry I didn't notice them, good questions, I'm not sure why the entire GG area has so many separate leases, its not hard to imagine though that over many years of prospectors in the area, various companies held different parts at different times.. I think its reasonable to accept the story THX have stated in terms a strategy to bring them all together.

Correct me if I'm wrong... and I may be wrong. But I've seen you mention Kyarra a few times.. I'm not sure that the location of Kyarra is key, but based on a few snippets that I have read it's that the geology first encountered at Kyarra was unique and very profitable. You might read in some places that the geology at Lydia resembled the Kyarra style. There's old docs around that mention the Kyarra group and schists. Check them out in articles like this:
