Broken bit off a sledge hammer? :lol:
If it's magnetic then it could be magnetite with some impuities like pyrite. Ore wise it depends on the levels of impurities as to it's viability for iron extraction. It probably will attract iron filings being magnetic itself and have crystalline structure but it looks small. It should leave a black streak across the back of a tile etc. but polished should be a bit of a dull metallic finish.
It does look very shiny steel like unless that is just the angle of the shot. Meteorites can be almost mirror like and have no crystal structure. From memory it would not leave a black steak.
Test its streak colour and look for crystals under a magnifier. Is that goldy colour pyrite?
