I had that happen to me i pulled off the side of 85 between Gila Bend and Buckeye to take a leak and looked down and saw a gold nugget when i picked it up you could see it was shaped like a butterfly , it was ground flat on the back side , near as i could tell maybe a piece of jewelry that fell off or out of a mount it was just under 1/4 oz.
No, private. But a neighboring claim is Roadrunner.
I have two adjacent claims in San Domingo and several on Turkey Creek. My partner wants to sell the San Domingo claims and concentrate on Turkey Creek.
I'm having a blast out there in Morristown. The bedrock is mostly visible in the creek beds and vacuuming them is yeilding good gold
Moqui marble is a name for hematite concretions from a specific location. Hematite concretions are quite common all over the world, and are known to be found in Arkansas.
Something else found in Arkansas are spherical pyrite nodules. Over time, pyrite can oxidize into hematite. I suspect that might be what you have here.
That's the right idea, noticing a rock different then the rest, but in general most meteorites will pull towards the magnet, and don't usually find them round. I think you have some native earth rock there my friend. Good luck with your new interest, they are out there. ht
