It gets attracted towards magnet towards small magnets. It's color is a mixture of brown, black and white particles. When exposed to sunlight the white particles is shining. The streak is white color. Fingernails can scratch the rock. It looks like a pebble.

Sounds like you've found a hot rock.

Rocks that set off metal detectors/pinpointers
Is there a list of rocks & minerals that will set off metal detectors? I found such a stone today--it was infuriating!!!! 🤬 After several minutes of sifting through substrate with my pinpointer expecting to find another rusty square nail, all that was left was one stone. It doesn't set off...

Hi. What type of signal did it give on your detector? Im guessing positive rising sound. Given its attracted to a magnet I'll guess positive and contains naturally occuring iron mineralisation in some form or another. There is also the possibility that a tiny bit of actual iron as it was rusting away oxidised with some surrounding small gravels or sand creating what looks like a pebble or rock. I have found those before.
I don't know what type of hunting scenario you found it in but when I hunt gold nuggets I never discard hotrocks before investigating them. Usually involves a hammer. Often I have found gold in them though more often than not they are just a rock.

It is very weakly magnetic.
