I have been walking through my woods on our property we own and found what I call a trail...Like a blood hound I followed the clues and started noticing rock on the surface shown below..My question is could these rocks lead to me finding larger crystals?

I have heard what is in our area..fluorite..hematite..thorite...magnatite and some more...and I do not believe it is just in the one area I heard so I have been searching around our land seems to me we are surround by these prospects and old mines I do not see it missing us lol...mind you I have been begging for the backhoe but hubby says no so shovels it is...I am going to clear up the leaves and such and see what is around and if I find some that would make it worth a trip and with his permission...as it is not just my land..see about who would like to come and find out what we have up here in the stix lol
