Hello Eric
That is the point I made a month or so ago prior to your discussion with Will...
You never know until you drill
In that respect, the ratio of G10's to G9's and/or high Chrome % Chromites is all the information I need to be interested, the rest is academic. Once found, the source kimberlite will and must be drilled... every time!
These G10/G9 ratios are very similar to the nearby Kenady Lake pipes on the same trend and the mag lows are of reasonably interesting dimensions. As you know, the DB/MPV pipe grades are largely economic.
Arguing the rest is like arguing how many angels can you fit on the head of a pin... its pointless.
I don't mean to be argumentative however, regarding the Soblov criteria,.. they/it does not account for or assure the diamond enrichment of the source rock, the efficiency of the kimberlitic scouring of that rock, the relative erosion of the emplaced hard-rock source or the enrichment, angle, depth/quantity of any backwashed and/or segregated tuffacitic backflow. A large pipe or narrow dike could just as easily exhibit G10's of Soblev parameters and still not be economic. Point being,... NO indicators guarantee grade or amount of ore, therefore I am sure you agree that ultimately, the only true indicator is the drilling, logging and ultimate acid dissolution of at least three deep triangulated RC cores.
High chrome % Chromites and/or G10/G9 ratio's always get my interest, but RC cores will always be required for evaluation, and even then, grade may be off by a considerable factor pending bulk sampling.
Regarding the Mag Map, there was no magnetic legend shown and as you know, the choice of cool and warm colours to depict lows & highs is entirely up to the technician with blue more often than not chosen to depict lows. In this case, I don't believe those were intense high's but rather, deep lows.
Best Regards and Happy New Year
