With ENR beginning step out/infill drilling at Emily (A & B below) and WA1 becoming active just south of Emily (access (?) lines only so far) here is a summary of Emily.

============
Compiling data on a Google Earth image.
Assays are selective with only higher grades, or the highest in a hole shown to give some idea of Nbx TREO ranges.
Lithologies come from section, previous comments, and a probability that anything above 0.1% Nb2O5 might be related to fenite alteration marginal to carbonatite. Such a zonation is common and also reported at Luni where there are marginal carbonatite dykes and fenite in a complex poorly defined arrangement.
===========
The section, below, shows a thin, relatively shallow (50+-m), sub horizontal blanket of high grade mineralization, some 300m long extending to the WA1 boundary.
Nbx TREO grades are low in holes 94 and 95 with the section showing carbonatite rather than fenite margin so generalizing may not be a good idea based on grade. Hole 229 shows a locally deeper level of transported cover and was probably NSA (no significant assays - not above cut off anyway).
It is open at depth but given aircore generally can't penetrate too far into fresh rock EOH probably represents this interface here. Below this grades are likely to drop off rapidly with only local high grade zones as seen in some of the deeper RC intersections for EAL098 (TD 180m).

==================
Moving forward?
PXRF and logging of lines A & B will determine whether another one or two 200m westerly step outs are necessary. Hopefully will be.
To the east 200 m step outs, as shown above, would be wise to show what, if any, continuity exists between 98-136, and east of 136. These do not need to be long fences and could be visible by the next clear satellite pass given the rate at which the A/C rig has been working at.
Will be fascinating to see the size of the southerly extensions onto WA1 ground.
As a target from geophysics Emily is certainly underwhelming.
However, 300+- m with a shallow 15m thick blanket of +2% Nb2O5 which is open to the south and somewhat to E & W shows possibly why ENR are drilling wide spaced aircore lines across the generally more obvious geophysical targets. Time will tell if it is a wise approach.
