At a total guess, the top line of cores might be weathered bastnaesite bearing ores but that is just a guess,  and the bottom appears to be a different carbonatite REE bearing ore type (albeit if follow the rows it is almost that within that drill core, and by that look at the last line in the top row, assuming it comes from the same core) it might indicate , note might as not sure whether we are looking at one core but assumption is we probably are,  encountering two different REE bearing laterite types (as per the graph in that Ann).   Obviously need to do your metalurgical testing for TREO and that is the question here – REE content and assaying is what will determine that.   If it is the same drill core and assuming each row is 1 metre that is 40 metres of drilling, 80 metres if each row is 2 metres.

Anyway for others that is just a guess but thought the following links might help.  Obviously high risk/reward here, but of interest appears they are drilling more holes than previous Ann.   This Ann suggests now 21 holes will be drilled whereas the initial Ann  on drilling stated  "The initial drill program will comprise ten (10) HQ diamond holes (or 1,000m of drilling).  Additional drill holes will be drilled if required."   So doing more holes than planned so you decide what that means and IMO that means two things – either 1) happy with what they are seeing so drilling more holes or 2) alternatively they are drilling at less depth than anticipated so can drill more holes with their allocated budget (Refer previous Ann here- Post #: 34765575):

Anyway, have a look at page 3 of the link below - Figure 2 drill cores might be of interest as a comparison to the cores here – top row in particular and make up your mind on comparison to these cores:

Have a look at page 8 of this link – the top picture in that page in particular:

Anyway you decide, risk/reward, could be wrong, but will be interesting what the TREO looks like.  Obviously market hasn't budged with this Ann.

All IMO
