khouse Posted January 30, 2017 Share Posted January 30, 2017 My buddy brought this thing back from a gulch in Colorado. He wasn't having any luck finding gold with is Atgold so he started using his magnet on his pick. He happened upon this thing. I don't know what to call it yet so it's a thing right now! LOL Anyway it stuck like glue to his pick but he told me his machine would not hit on it! I told him he must of had his machine set up wrong. OK. So I bring it home and tried my Atpro on it with my already set GB to 80 and not a peep at full power, Pro zero with no disc! I then lowered my GB to around 60 and there I could get a hit. It would not hit at the center of the coil but would hit as the coil approached and departed the target with an iron tone. The Propointer A/T won't peep even touching this thing but yet it is strongly attracted to a magnet!! It's small and heavy weighing in at 2.7oz. What the heck is it???

Steve Herschbach Posted January 31, 2017 Share Posted January 31, 2017 My guess is magnetite. Link to comment Share on other sites More sharing options...
Glenn in CO Posted January 31, 2017 Share Posted January 31, 2017 I agree with Steve, that is magnetite. Here is a some magnetite found near Badger Flats that we found last year that wasn't water worn. We used a magnet to find the specimens. 1 Link to comment Share on other sites More sharing options...
khouse Posted January 31, 2017 Author Share Posted January 31, 2017 Some magnetite looks like meteorites. So this is close to invisible to my ATpro unless I manually drop the GB way down. Then it still gives a funny iron tone. Anyway if it was intact a meteorite would it then give a positive hit beings it should have some nickel in it? Also are there meteorites will little to no nickel? Just trying to get all my facts strait before I tell my buddy it isn't worth $50,000.

Lunk Posted February 1, 2017 Share Posted February 1, 2017 Logically, if your specimen is in fact a meteorite with very little or no nickel, it would only be very weakly attracted to a magnet. The fact that it is strongly attracted to a magnet, gives a null response on your detector and has no discernible fusion crust or regmaglypts (thumbprints) points to a terrestrial origin - magnetite. Also, only freshly fallen meteorites are black, and they have a smooth, uniform surface, never broken up and pitted as the surface of your specimen shows. Example of a freshly fallen stony meteorite: 3 Link to comment Share on other sites More sharing options...
