I have reached another level of my Spring archaeological dig and lo and behold I found a copy of my post #75309 (10/05/21) where I recapped the NioCorp MD&A for 9/30/13, not a typo 2013. Thanks again chico for the reference.

My post is worth a re-read (IMHO).

The MD&A is really worth a read

Pages 2 - 12 A wealth of information about the historic drilling, and TREO. Any question concerning whether or not REEs are there should be answered.

The obvious point is that at that time, as well as the time the decision for the current FS was made, and possibly even now, the cost of an underground mine 200 - 300 meters underground for ONLY the REE probably was/is not economic. However, at this time with Ni-Sc-Ti carrying the bulk of the cost of digging the ore out of the underground ore body the REEs should be profitable despite the volatility of REE pricing.


In my post:

Three zones of anomalous REE mineralization were identified outside the core historic niobium resource zone, during the wide-spaced exploration drilling. The results of some of the holes are

[[ Table provided could not be “cut & pasted” summarizing
Drill Holes - 9
Quantity of REE mineralization intercepts - 13
Total meters of REE mineralization - 853.7
Weighted average of TREO % - 1.37%
]]

I couldn't "Cut & Paste" the table on page 5 before but have taken the time to recreate below:

Healthy intervals ( may not be true thickness) and healthy percentages of TREOs.


Pages 7-12 of the MD&A include info, in text and table form, about light, medium, heavy and TREOs.

I don't know how much of the info, and which piece of the info, pertains to the "ore blob" that the current FS plans to mine. Depending on the results of the revised mineral resource the targeted "ore blob" may be changed.



Time to walk in the spring sun and mix the first G&T of the year.
