Could you please advise if this is galena, even if attracted weakly by magnet?

Hello everybody ,

 

Could you please advise if this is galena, even if attracted weakly by magnet?

 

The samples are very small, and I would like to know what minerals are they.

I thought that it is galena, but it shouldn't be attracted by magnet, or it could have iron in it. Is any way I can check the composition at home?

Is it iron pyrite?

Thank you in advance for your help.

My first thought was pyrite, but pyrite is more than weakly magnetic.

I have found them both together, are similar by color, but the structure is different. Any chance it could have silver in it?
It is possible, but unlikely, as silver doesn't form in most minerals like that. The structure looks like pyrite, maybe some sort of mix?

It's not galena if its slightly magentic. Some possibilities would include hematite or pyrrhotite.

The crystal structure doesn't look like hematite, at least I've never seen any form of hematite like it. Pyrrhotite does seem more likely, at least in my opinion.
