Ann: Yin Extended by 1km & 2.5km of High-Grade NdPr Discoveries, page-88

Summary of drilling reported on magnetic base. Orange circles RC and DD holes in this announcement. Planned holes in yellow - most have site preparation visible on Sentinel.

Majority of RC drilling has been on Yin south where two rigs have probably been working in tandem at different prospects/parts of Yin South judging by the sequence of hole numbers.

Starting with the big bend area (my name for reference only). and northern section of Yin far south.




Hole depths show they have expended a lot of meters down here. If they are hitting anything then likely to be deep or multiple zones requiring consistent drilling to 100+m.
Updating a schematic section through hole 213 where assays were reported gives what may be a type section for this area (hole spacing and depths only at this stage) and to the south where there only 3 40m spaced deep holes on all but one line.





The original plan for southern Yin mag follow up was for 2 holes per fence. Spacing is a nominal 40m between collars on the same fence which means holes to 80+m should give overlapping coverage. The above and most to the south far exceeds overlapping coverage. Why?

Drilling at 'big bend' was expanded with another two holes per fence making it 4 in total. The cost of an additional 1000+m or RC hints at some positive results with knowledge gained resulting in a modification of the program south of the Lyon River - Yin 'far south'.

Further south there are some relatively shallow holes.



Missed this drilling on Sentinel. Even knowing where sites are they are mostly subtle. Good from an environmental perspective not to cause a lot of disturbance.
Drilling is targeting a south dipping zone here (becomes west dipping and all over the place to the north....). This SW end is more 'normal' in terms of drill depths but still quite deep. Cover sequence here?
There must be some encouragement to warrant drilling the original 2 plus a 3rd for most fences.
As mentioned above Pxrf is in use even if not used for the announcements.
========
Yin North and Y2
Site preparation has begun on planned holes on magnetic "splays" from the main trend.
The northern area has five fully prepared sites.

Green circles prepared sites. Red mag trends.
Blue circles are proposed infill not prepared....yet.

The southern area is not clear on Sentinel. Something has happened - access and a site or ?more done. Schematically the sites are targeting mag with associated weak TREO rock chips.



Y2 - probably a few more holes planned than shown on the image above.

Schematic sections showing location of diamond holes. Closer to 172 and 173 than shown - basically twinning these RC holes.








Plunging zone to SE??
Getting too deep??

======================
C3 and C7
For detail locations.
c3


Magenta circles are possible drill site interpretations. Other than those the only addition is the diamond holes which, for the most part, are twins of inclined RC holes (CD2 & 6 near vertical holes)


C7

Major change in plans from 160m spaced grid to 40m spacing on two fences. Drilled in mid May - clear enough in hind sight.

========================
Haven't looked at sections based on assay results ...yet.
