Hey JD.....as usual, a thoughtful post.....yes DD for sure, you've done yours and one of them is SPQ(me too)......I'm curious about the 'motherload' issue which is brought up quite frequently. Is it possible that there was no 'motherload'?....ie...mineralization got emplaced in the crust slowly, from VERY deep....and there never was a singular 'motherload' but more of a long term 'seepage' before the conduits cooled? OR....is it also possible that the 'motherload' or bulk of the mineralization was eroded by repeated glacial epochs? ...TIA....sambone
