Ann: Broad, High-Grade Assays at Yin REE Discovery - Mangaroon, page-50

An extremely conservative back of the napkin guess. I'm not a competent person in these mineral systems, have only spent maybe an hour on this, and this is only based on data provided in this announcement - which is inadequate for anything but a yawn.

-assumed all holes pending assays are barren, except the infill holes to the south.
-modeled the largest intercepts only, ignoring all the small secondary ones.
-cut off the volumes at 150m depth, even though there are intercepts deeper than that.
-used very conservative interpolations
-assumed density is 2.8 across the board.



Mineralized volume using above modeling parameters is 1.642 million cubic meters, which is about 4.6 million tons using a density of 2.8.






Length-weighted and un-weighted mean for TREO filtered to the above modelled volumes. A kriged block model would probably fall somewhere in between.


Based on some of the cross-sections in the announcement, the holes pending assays to the north and south look to have logged mineralization, presumably informed by pXRF.

My thoughts:
- I suspect the lads might get their first tranche of performance rights by after the maiden resource from Yin alone
- I don't see an obvious 'sweetspot' in the deposit yet (including the area in the south they have drilled out a bit), and by the looks of it this thing could extend both north and south quite a ways with as good or even better grades and thicknesses yet to be found.
-Looking forward to news on the carbonitie prospects.....
