"The numbers all look right to me personally, it appears the confusion came from Mineral Resource Estimate vs Ore Reserve Estimate, the latter being what you are using, so thanks for clarifying."

Yes this version of the chart was specifically for comparing reserves. I have another version which compares Total Resources and another for Measured & Indicated only.

Thanks for letting me know that the Authier ownership is the same as NAL. My information had come from the 10/11/2022 Noosa Mining presentation (and possibly presentations before this):


Presentations after this do not mention the ownership of Authier until the presentation on the 26/5/2023, which is consistent with what you are saying (though I couldn't easily see any announcements which reflected the change in ownership - perhaps it was just an error in the earlier presentations):

The latest Noosa mining presentation 20/7/2023 goes back to not being specific about it - which is unfortunate because clarity on ownership structure is important and (selfishly) ambiguity makes my life difficult... not to worry. Here is the updated version of the same reserves chart with the 75% ownership of Authier now accounted for which also impacts the PLL resource size and valuation:


This is the chart for Total Resources:


Which is based on the following:


Again, let me know if you spot anything else that I need to look into.
