Silver rock ore?

[CrazyAcres]

We just bought land in Tennessee in the Appalachian Mountains. As we were exploring our creeks we found these two rocks. Just wondering if anyone could give us an idea on what these rock are?

Both are shiny silver on the outside. I did manage to break one open and have posted pictures of that as well.

Found in the creek at the back of our property:




The part I chipped off of the above one:


The one from our creek at the front of our property:

Is it kind of light for the size? I think it is melted aluminum. Silver would be black.

What does the assay say?

Time for more coffee.

They are about the average weight a rock would be that size. Not really light weight nor heavy really.

First thought is Galena, which can be found in your state.

Try a streak test. Most of the images are to blurry on zoom to see any detail except around the fringes where things came in focus. I suspect its quartz with very fine mica schist in it or possibly pyrite. If there was galena, ore of lead, it'd be heavier so a streak test will help, also look at what the break up of the streak looks like because if its mica it'll leave little glittery bits in the streak.

Slag most likely, unless you provide some better pictures.
