Ann: Lyons REE Project Maidel Drill Program Update, page-19

Not certain where you got the 17 holes. They certainly prepared more sites than that if the earlier interpretation of Sentinel is correct.

There are undrilled sites at Lyon 11 plus at least 10 more at the north end of Lyon 12 13.



Note this is interpretive. Treat with care.


The small squares were the locations of site preparation interp. The drilled interp sites (white filled circles) are consistently 10-25m off set from these site prep interps. The actual coordinates will be different again. For HC purposes these 10-25m discrepancies are IMO OK as we are dealing with indications rather than needing high levels of precision that is probably not possible with these data.
There will be errors and omissions in what is hopefully a reasonable attempt at interp.

Yesterday I commented that there is a reasonable chance the ironstone is dipping SW.
The number of drill holes (est. at 19) drilled since late Sept (?29th) suggests rapid progress with drilling.

This combined section plan attempts to show what may be happening with the dip of the ironstone.


The blue line would represent a vertical dip for the ironstone. Drilling could be from either side and not impact results greatly. If the drill sites and surface location of the ironstone are reasonable then to drill some 10-20m past this vertical zone would require some 350-400m for this one section. There are some 5 sections with 3 sites so 1500-2000m in 4 days. Extend the period a bit and it is possible but not likely.

The possibility of drilling this number of holes and required metres increases the shallower the dip becomes.

Speculation but IMO a relatively shallow "SW" dip is possible. HAS has similar dips at Fraser's, Simon's and Bald Hill.

===============

No definite implications for grade and thickness from this density of drilling. IMO it was planned to be this dense based on the site preparation. If they were not hitting anything of interest then would the drilling be modified to testing wider spaced lines and leaving out some prepared sites? Probably.

HAS deposits seldom exceed 5-10m down hole length of ironstone and commonly less. Hopefully LNR are seeing this at least and better still Yin first line down hole intersections.


PXRF will give them some idea of what they are seeing but reporting such readings is up to the BOD.

It worked for DRE where PXRF and assays correlated well - even a tad low for the XRF apparently.
