Hi all!

I found this with my metal detecting pinpointer in a park here in the UK. It was just beneath the soil (about an inch down). I couldn't believe the strength of the signal given how tiny it is (maybe 4mm on the longest side). I initially thought it was iron or lead but after closer inspection - I have absolutely no idea!

It's 0.24g, and doesn't react at all to a very strong neodymium magnet. It does however make my pinpointer scream from an inch away! Any ideas?

Cheers,
John

It reminds me of some aluminum foil that someone had thrown onto a fire to burn.

Other than that I have no idea, sorry.

Good luck on finding out what it is.

Thanks for the replies guys! Visually - I see what you mean regarding melted aluminium but I think it's probably too heavy. Could very well be copper although I thought it might be greener? I honestly don't know enough about this subject so filing it is a good idea!

Do you have a standard discriminating metal detector you can check the digital Target ID (gTID) with and report back?  Also, what is the pinpointer you are using?  That red color seems odd&interesting to me, as that color isn't typical among common naturally occurring materials, in my experience.  And even if man-made I don't think it's common, particularly if this has been exposed to (or created from) high heat.

More data needed!

      Out detecting the other day and had a signal on the Monster that sounded like your typical hot rock but when I dug the hot rock out it didn't look like my typical hot rocks in this area?  So I took the time to flip the rock over and ran the coil over the other side of the rock and the Monster said GOLD!  So after some scraping I see nothing and I'm too busy hunting and throw the rock in my pouch to bust it open later at home.  Needed to go into my pouch for something tonight and found the rock I'd already forgot about and scraped the piss outta it and saw nothing, ran coil over scrapings and the rock and still a gold signal but no sight of gold?  Took rock inside and took the steel wool to it and finally saw the glint of a little gold so proceeded scrubbing cautiously and found the little flake.  This guy almost got away.  Moral of the story...if it sounds like gold you might want to pack it home for a THOROUGH check.....

      Found this brass tire stem and cap down deep. I don't know what it is off of or how old it could be. Strange it was in the water.

      Can any of you tell me what this is?  A gift from my father when I was young.  He traveled all over the world so his location does not help.  It is about the size of a large hand.

      Meteorite or rock?

      Found this today kind of looks like possibly a Chromite meteorite but not sure so hoping some one could help. Browsed some pictures of
      small Chromite meteorites on google images and seen some similar.

      Dimension is about 1.5" diameter and about 40 grams heavy.
      Not magnetic checked with magnet and my Garrett Pro-Pointer II detects nothing
      Found in London, Ontario, Canada

      Any help would be great
      Thanks
      John

      Morning!
      Can you tell me what it is? I found this in Central Florida and the only "rocks" we have here are fossilized corals. But it was near the "landscaping rocks" pile people in FL buy and litter their property with, so it could be part of this pile and in that case brought from out of state. It is very heavy and feels solid. 2 corners are chipped and some different yellow material shows through.
