these are some of material from a hydro thermal deposit ,figured i would share what i found. located this pocket the old fashion way,looking for natures billboards,an old timer once told me when i was a kid,always into rocks,he said sometimes nature will point the way for ya, you just got to learn how to read the signs nature gives you,he said of (pockets) some times will have huge signs saying(here i am), he said ,did you ever see a tree growing out of the side of rock wall ,and wonder how does that tree grow where theres no soil ,just solid rock,well trees cant grow out of solid rock ,so whats that tell ya, those roots are going somewhere, sometimes just a crack,but sometimes theres a pocket there,and pockets are natures (goodybag). its held true more often than not! i always listen to old timers, it most often pays off!only this sphalerite,and calcite,and some quartz so far. but i got buckets of it.
