Some sections for the west end of Crean.

9 15 CREAN SECTIONS WITH GRADE WEST END SELECTED ONLY.pdf


An example with some observations/thoughts.


These are rough and interpretive so DYOR.

• Only assay results at or above 0.2% Nb2O5 (Nbx) have been reported.
• Carbonatite zone softer and/or more deeply weathered. See previous sections 4 & 5 in PDF.
• Grade "smearing" not a major issue with residuals well above 0.5% from figures available.
• Western end likely to be only some 50+- m wide. Maximum 100m but time will tell with RC holes already drilled probably further into bedrock than aircore penetration allowed.
• The high grade zone (>2% Nbx) is some 1 Km long and open, somewhat, to the east albeit at probably lesser grades except locally (1-2+% Nbx) with more results still to come.
• No carbonatite or elevated Nbx grades 200m west of section 1. Nominal hole spacing 40m with most holes drilled to around 80m (range 67-88m) suggesting near overlapping coverage and unlikely to miss a significant sized carbonatite. There is some carbonatite in hole EAL1 (at depth) though no hints from the follow up aircore are mentioned.

============================
Will probably go through the Green data along the same lines as above. Slow process without good software. Hole deviation is seldom an issue with aircore as it is used to take representative samples, most of the time.

As with Crean west I expect there will be some good, but RELATIVELY SMALL ZONES OF HIGH GRADE. Already noted at the west end where spacing is 400m so there is some potential for continuity and size.
Simple observations from collar data/assay data for Green shows holes 432-3 and 487-513 were drilled vertically. For sub horizontal blankets this would make some sense. Eastern end no significant Nbx in assays.




These observations are probably along the lines of what @ozblue is posting about. Devil in the detail. Sometimes some gems tucked away as well so always worth looking in detail beyond the headlines.
