The greater the pressure the greater the release of subsurface minerals. In the HM case these spider web of sulfates where forced above via great pressure over a vast area which is expressed by what i could see looked like spider webbing vienlets of gasous vienlets thus solidified into a mass by the cooling off of the mioneralization. These webbings should give JB*BOD the roadmap needed to aid in staying in ore source if the pattern is a constant. Meaning they need to stay in the constant until it leads to a higher quality roadmap. eventuall all of the spider webbing should lead to SOURCE/ magnetic high. For such a web to be so far from the deep magnetic high would say great pressure was needed to travel so far. Which indicates that a lot got left behind, down there in the deep stuff, the stuff which looks real good on ZTEM! So lets follow the web, 2 miles and just getting on the road!
