My geo friend agrees with you about the probable size of the plug and the fact that such a small plug cannot generate so much sulfides.

Consequently, these sulfides must come from outside the plug or the
plug is part of a larger differentiated mafic intrusive which lies down below and brought up to surface by the granite intrusion.

Here are some facts and a possible conclusion:

1) This «plug» is located within the granitic batholith;

2) It is not intruding the granite since this granite is the last
intrusive in the area, according to government reports (if we forget
about the younger diabase dikes);

3) It is differentiated (gabbro/norite) and sulfides too are to
differentiated (disseminated to massive);

4) It is too small to have generated that much sulfides;

His theory is that it is a remnant of a larger intrusive, probably the
bottom of the Rocher-Quenonisca differentiated intrusive. There are many such remnants in the SE part of the batholith.

Any comments, mineman?
