Mesothermal deposit, magma chamber, etc...

FYI: GREAT post by coach247 on KXL board.
For those too lazy to read it... the post talks about the high probability that the Hercules discovery is mesothermal in origin (i.e. "deposits formed by hot water moving through rocks as the surrounding rocks were uplifted from deep in the Earth’s crust") and how such deposits are formed etc.. You really shoud read it. Awesome job.
As I read this post I was immediately reminded of the multiple references SGX made to a 'magma chamber' in previous NRs re: Jacobus Ni-Cu drilling... a phrase first used in the July 24, 2007 NR when SGX drilled 15.15 g/t Au over 0.73 m @ 389m depth and stated: "This gold-bearing horizon represents a new zone of mineralization that is not related to the Ni-Cu mineralization within the gabbro." and "However, the presence of pyroxenitic fragments which are estimated to be 10 per cent of the fragments in the inclusion-breccia mineralization suggests that at least some of the fragments were derived from an ultramafic part of the intrusion or from a magma chamber in the lower crust."
Mentioned aagain in Oct. 4th, 2007 drilling announcement: "The gold occurs in a pyritized carbonate-rich section of chloritic tuff within the andesitic volcanics that overlie the gabbro. Sage has re-examined core sections from previous drilling and has interpreted that the gold-bearing zone is also present in hole 9."
With all the talk of 'mesothermal deposit' and 'magma chambers at depth'... Is it possible SE Jacubus mag high within which is a northwest-trending low, which is interpreted by Sage to be a similar geophysical signature to the Kodiak Golden Mile quartz vein system, represents to source of mineralization? longbomb do you have a map of mag signature of both KXL and SGX properties?
Just thought it was interesting.
