Looking at the pics ..... it looks like it has some iron on it . That could make it hot on the MD .
Maybe ... Liroconite ... Hauyne ... Cyprine . Did you find it in an area with limestone ?
This stuff in the following pics has a speck or two of gold on it . Don't look like the same make up ( matrix ) of yours , but I would take a good look at that stuff your on if I were you .
hmmm
we talking about Bosnia and there are things you cannot imagine.. well i will search throw these names and try to recognize some.. but first..
i am on the zone where there is no stones and rocks just soil only samples of many color flint stones ( white, green, blue, gray etc and red..with these res you can easily start the fire)
but mile away we have land with such blue-green-black stones and some yellow limestone as you say.
maybe 50- 50%.
it is like this: in attachment i added same stone but black one and it is difficult to see that is actually blue one.
but these blackish rocks does not beep so well as blue-green!! so if i discriminate this black stones it wont beep..just some noise..on other side this light bright ones have no problems with higher discrimination even smallest pieces..
black rock is also easy to brush and make something out of them while lighter blue ones are more though and they can crack into crystals..
another big thing: on same place people live with no trouble 100 years and there is on same spot a spring of water that we used to drink - all people from villages around.. then some guy took sample of this water to USA and won first price of a 600.000$ and next year also first, then he was second..but with our water he became rich as..well maybe someone knows but Clinton used to drink that water and promoted it like the best one on the world! now a days this water has a name and it is OAZA..
another one: this place has also many other water not only mineral..and there is also some gold..yes gold..but on my site i didn't found it just some red gems??!! not sure if these are from blue rocks because i can see samples of red color. but this creek water i was looking for is not the same. This flows to the north and gold one on the south! Still cannot tell you if it is really golden because i still have to search this one.
Ed T said copper..well there is some mines but more on the south cca 30 Km away.. on this site is only daily surface mine of an Anthracite! We used it like coal but it melts our furs so we rather use plain wood.
shall i look this type of rocks with copper in it??
(Wikipedia) Lapis lazuli is a rock, not a mineral: whereas a mineral has only one constituent, lapis lazuli is formed from more than one mineral. hmmmmmmmmmmmmm
i looked some pictures and i thought that there is only bright blue colors!! but it seems it can be also dark as mine specimens!
could be this solution???
if i remember some other detail i will post.
thank you very much for all help and info!! hope that it turns to be a good stuff
