Strongly magnetic, or slightly magnetic? Maybe magnetite. Possibly some pyrite in it for the sparkle.

Strongly magnetic. The larger one weighs 29lbs.

That be my guess.

I have to agree with Blackfoot58 and tamrock. But... don't take my word for it!

I’m thinking pyrite would make sense too, other thought would be hematite but it’s more of a silver sparkle in my experience.

The only common naturally-occurring terrestrial mineral which is strongly attracted to a magnet is magnetite. Native iron is rare in nature and almost exclusively confined to the far northern hemisphere. Neither hematite nor pyrite are magnetic, except when magnetite is also present as a secondary mineral. It's common for iron minerals to be a mixture of oxides, and sulphides such as pyrite may also be present.
