Ann: Assays Confirm Yin as a High-Grade Rare Earth Discovery, page-59

Hey AWASP, I also like that quote.
I think the similarity they are drawing is only based on the NdPr to TREO ratio at this stage. Yin is floating around 25-31% based on the drill intersections compared to Yangibana which is around 30 to 35% based on their mineral resource statement (up around 50% at Simons Find).
e.g. at Yangibana the combined measured, indicated and inferred resource of 21Mt at 1.17% TREO and 0.4% Nd₂O₃+Pr₆O₁₁ gives 34% NdPr:TREO.

But the difference is for Yangibana we know that’s from an average concentration of 3,150 ppm Nd and 810ppm Pr, as well as knowing all the other REE concentrations. So, can’t really go much further with comparisons at this stage other than to say based on initial drilling the TREO at Yin is a bit higher and the NdPr% is a bit lower, but they both have exceptionally high NdPr% to TREO ratios compared to other major deposits.

At least that’s my take on the similarities without getting into potential tonnage etc.
