Strange object found with Mineoro 205

[Esteban]

I found this strange metalic-stone object, very heavy, with Mineoro 205 two controls. Produce few beeps, and search the small area of the beeps and found this. I try with my Bounty Hunter detector and the tone is the high, White's detector also show like precious item as dollar coin silver-size. Also I try with strong magnet and nothing, isn't ferrous.

My question is: in the zone no rocks, only regular soil: Can be non-ferrous meteorite?
